Illinois professor Paul Braun’s lab look like any others, but they pack a surprise inside.
Electric car charging. Aside from quick-charge consumer electronics, batteries that can store a lot of energy, release it fast and recharge quickly are desirable for electric vehicles, medical devices, lasers and military applications.
Braun’s group developed a three-dimensional nanostructure for battery cathodes that allows for dramatically faster charging and discharging without sacrificing energy storage capacity. The researchers’ findings will be published in the March 20 advance online edition of the journal Nature Nanotechnology.
Aside from quick-charge consumer electronics, batteries that can store a lot of energy, release it fast and recharge quickly are desirable for electric vehicles, medical devices, lasers and military applications.
“This system that we have gives you capacitor-like power with battery-like energy,” said Braun, a professor of materials science and engineering. “Most capacitors store very little energy. They can release it very fast, but they can’t hold much. Most laptop batteries store a reasonably large amount of energy, but they can’t provide or receive energy rapidly. This does both.”
The performance of typical lithium-ion (Li-ion) or nickel metal hydride (NiMH) rechargeable batteries degrades significantly when they are rapidly charged or discharged. Making the active material in the battery a thin film allows for very fast charging and discharging, but reduces the capacity to nearly zero because the active material lacks volume to store energy.
Braun’s group wraps a thin film into three-dimensional structure, achieving both high active volume (high capacity) and large current. They have demonstrated battery electrodes that can charge or discharge in a few seconds, 10 to 100 times faster than equivalent bulk electrodes, yet can perform normally in existing devices.
This kind of performance could lead to phones that charge in seconds or laptops that charge in minutes, as well as high-power lasers and defibrillators that don’t need time to power up before or between pulses.
Braun is particularly optimistic for the batteries’ potential in electric vehicles. Battery life and recharging time are major limitations of electric vehicles. Long-distance road trips can be their own form of start-and-stop driving if the Dell Vostro 1520 Battery only lasts for 100 miles and then requires an hour to recharge.
“If you had the ability to charge rapidly, instead of taking hours to charge the vehicle you could potentially have vehicles that would charge in similar times as needed to refuel a car with gasoline,” Braun said. “If you had five-minute charge capability, you would think of this the same way you do an internal combustion engine. You would just pull up to a charging station and fill up.”
All of the processes the group used are also used at large scales in industry so the technique could be scaled up for manufacturing.
They key to the group’s novel 3-D structure is self-assembly. They begin by coating a surface with tiny spheres, packing them tightly together to form a lattice. Trying to create such a uniform lattice by other means is time-consuming and impractical, but the inexpensive spheres settle into place automatically.
Then the researchers fill the space between and around the spheres with metal. The spheres are melted or dissolved, leaving a porous 3-D metal scaffolding, like a sponge. Next, a process called electropolishing uniformly etches away the surface of the scaffold to enlarge the pores and make an open framework. Finally, the researchers coat the frame with a thin film of the active material.
The result is a bicontinuous electrode structure with small interconnects, so the lithium ions can move rapidly; a thin-film active material, so the diffusion kinetics are rapid; and a metal framework with good electrical conductivity.
The group demonstrated both NiMH and Li-ion laptop batteries, but the structure is general, so any TOSHIBA Satellite A200-180 Battery material that can be deposited on the metal frame could be used.
“We like that it’s very universal, so if someone comes up with a better battery chemistry, this concept applies,” said Braun, who is also affiliated with the Materials Research Laboratory and the Beckman Institute for Advanced Science and Technology at Illinois. “This is not linked to one very specific kind of TOSHIBA PA3356U-1BAS Battery, but rather it’s a new paradigm in thinking about a Dell XPS M1330 battery in three dimensions for enhancing properties.”
The U.S. Army Research Laboratory and the Department of Energy supported this work. Visiting scholar Huigang Zhang and former graduate student Xindi Yu were co-authors of the paper.

Top 20 Ways To Extend Your Laptop Battery Life
10 Must Have iPad 2 Apps For New And Existing Users
What 10 years of Apple did to its main product
The gadgets you love don’t always love you back—at least when it comes to battery life. But you can get more from your laptop, your iPod, your phone, and other devices with these 10 techniques.
10. Turn C batteries into Ds with quarters
Only a few things ever need D batteries, but who has them handy when you need those things? If you’ve got some slightly more handy C batteries around, you only need a few quarters to turn them into makeshift Ds. You won’t get the same longevity, and you’ll have to part with up to $1.50 for a bit, but it works, and it might just turn you into the family hero when you rescue that seemingly useless big-lens flashlight.
9. Keep your iPod “held” and updated
If you haven’t hit the “Update” button since you got your iPod, old or new, fire up iTunes and do so—the newest firmware, in many cases, can boost your battery life. Once you’ve done that, run through Playlist Magazine’s battery saving tips, which include keeping backlighting, the equalizer, and Sound Check features off when they’re not needed. Also, keeping the “Hold” switch in place when you’re not actively using it saves you from accidentally playing your whole collection, and wasting another charge cycle.
It’s a help to the environment, and your checking account, to use rechargeable laptop batteries instead of letting your Wii remotes and other gadgets eat through AAs. But the grocery store brands and accessories often don’t seem worth the hassle. Blogger Jeff Atwood does know what works, though, and he details the circuit science and recommends the good stuff in the post linked above. If you’re stuck with Energizer and Duracell choices, though, here’s Gizmodo’s faceoff of the big brands.
7. Turn off your digital camera’s screen
Having a view of the whole scene you’re shooting is one of the digital camera‘s big advantages over film-based models, but powering that tiny little LCD takes quite the toll on your little camera batteries. If you’re running low, or know you’re going to be without a recharge for some time, turn the screen off and shoot through the optical viewfinder. You’ll save battery time, and might find a new perspective on focus and framing.
6. Watch movies from hard drives, not DVDs
Simple, sure, but not always obvious. On many planes and trains, laptops serve as little more than portable DVD players with bigger screens, but forcing your laptop to spin the discs and read from them eats up more power than reading a file off a hard disk—or, perhaps even better, a USB drive. How to get there? We recommend HandBrake for most any system, though Adam’s got a pretty good thing going with his (Windows-based) one-click DVD ripping solution.
5. Extend your not-so-hot iPhone life
A lot of lists out there offer to help extend your iPhone‘s battery life. This one’s a lot like them, except it’s written by our sibling site Gizmodo and based on extensive testing done during the run-up to the iPhone’s launch. And it goes so far as to suggest what the others don’t—playing games with 3D and vibrate, for example, is a power killer, both in actual juice and in how long you’ll end up playing without realizing you’ve been sucked in. And if you’re just checking weather, emailing, and making calls, keep your 3G switched off until it’s needed.
4. Stash your gadgets out of your pockets
It’s the most natural place in the world for your cellphone or iPod, but the heat your pocket picks up from, well, your hips can decrease the overall life of lithium-ion fujitsu laptop batteries. Not so much that you absolutely have to get one of those I’m An Important Person belt clips, but if you’ve got a coat, purse, or other place to put a battery-powered gizmo, consider offering it a little more ventilation than your body-warmed cotton wraps. While you’re thinking cool, try stashing your notebook batteries (just your batteries, mind you) in the freezer if you’re trying to conserve every last drop while you’re away from your batteries charger.
3. Get long-term battery life
An inquiring reader asked how to keep his batteries delivering on-the-go power for the long haul, rather than watch his investment be eaten away by age. As is so often the case, our readers came right back with answers. A MetaFilter thread linked by one helpful reader suggests using the battery fully if you’re going to use it, then re-charge when it runs down. A Battery University link offers more tips, and Apple’s guide to batteries suggests a few tips on what to do with unused or spare batteries—store them in a cool place at about 50 percent charge, for instance.
2. Make your system smarter about power
Windows and Mac OS X both know when you’re using a laptop, and presumably want to help you save power. Except, in the case of the Mac, sleeping and hibernating isn’t done with remaining battery power in mind, and on Vista, well, all those Aero effects and background processes suck up power too quickly. Enter Vista Battery Saver, which kills the Aero effects, sidebar widgets, and other power sinks, and SmartSleep (OS X), which gradually transitions from sleep, to sleep-and-hibernate, to full-on, session-saving hibernate as you start winding down from 20 percent charge. Both are nearly necessary downloads for road warriors lugging either OS around.
1. Recalibrate a laptop battery to regain life
Fujitsu laptop battery >> Fujitsu lifebook t4210 battery
It’s a shame, but laptop batteries can lie to you about how much juice they have, or can really hold. The New York Times explains in a Q & A (look halfway down the page) the most straight-forward means of getting the real truth. Turn off all your interrupting apps, like screensavers and the like, put your computer to sleep, and plug it in until you know it’s good and charged. Then turn it back on, make sure your power settings are such that the system won’t try to sleep or hibernate, then run your computer all the way down on battery power. Charge it back up one more time, and you’ll know whether you really need to start shopping at Laptop Batteries Company, Discount Laptop Batteries Shop or check with your batteries manufacturer to get a new lithium stick.
How do you get more power from your battery-powered gadgets? Whether it’s a laptop, a phone, or something we haven’t covered here, tell us (and link the how-tos) in the comments!

20 Ways To Improve Your Laptop Batteries Life
Being an optimistic type of guy, I had hoped to pen a Five of the best from Computex 2012 feature. Alas, there’s not a great deal to write about. Not in terms of new tablets and smartphones, anyways.
Indeed, one of the biggest stories out of this year’s Computex was HTC’s absence from the first wave of Windows 8 tablets. Supposedly Microsoft had reservations about HTC’s prior performance in the tablet field, not to mention a recent cut in sales forecasts. Oh dear.
But I digress. Let’s get back to these new devices. Windows 8 was the star of the show, and that’s exactly what these three chaps rock.
Asus Transformer AiO
We haven’t written anything about the Asus Transformer AiO just yet, and with good reason. See, it straddles the boundary between tablet and desktop, with a massive 18.4in display. Not exactly the kind of tablet you’d use to play Angry Birds on the train.
Asus is a big fan of convergence, and the Transformer AiO – as I mentioned – doubles as a desktop, with a big fat base station type thing.
At the moment, Asus Transformer AiO specs remain elusive. Not even a whisper on resolution. However, we do know that the Asus Transformer AiO will rock Windows 8 and Android Tablet.
A dual-booting tablet/desktop hybrid? It could only be Asus.
Acer Iconia W510
Taiwan-based Acer revealed two Windows 8 tablets at Computex 2012, namely the Iconia W510 and Iconia W700.
You know sometimes you see a tablet or a smartphone or whatever, and you just want it? That’s exactly how I felt when reading about the Acer Iconia W510. No offense, Iconia W700.
Not exactly a unique concept, but the Acer Iconia W510 has a keyboard dock, extending battery life to a juicy 18 hours. The tablet portion can dock either way, so you can use the keyboard as a, uhm, keyboard, or as a stand.
Other than a 10.1in IPS display and 8MP rear camera, exact Acer Iconia 510 specs are fairly guarded. It’s thought to host an Intel chip, so that’ll be Windows 8 as opposed to ARM’s Windows 8 RT.
On the poop side, Acer Iconia 510 price will be somewhere in the region of $599 to $799. Hmm.
Back to Asus for the final in our top three from Computex 2012, and yes – it’s another hybrid beast. The Asus Taichi is part laptop, part tablet. But wait; it gets better.
The Asus Taichi doesn’t have just one display. That’d be ridiculous. Nope, it has a standard laptoppy display above the keyboard, and a second – effectively a touchscreen tablet, of sorts – on the back.
Both Asus Taichi displays boast a resolution of 1920 x 1080, with IPS goodness for angled viewing. There’ll be two options when it comes to size, namely 11.6 and 13.3in.
Other Asus Taichi specs of note include an Intel Core i7 processor (again that means Windows 8 as opposed to RT), 4GB of RAM, a pair of USB 3.0 ports, micro HDMI and a mini DisplayPort.
According to sources of good old DigiTimes, the Asus Taichi is estimated to have a Build of Materials (BOM) value of $900, which means price could – in theory – start around $1,300. Good lord.
Speaking at Dell’s Technology Camp event in London, the company’s vice president of End User computing, Erik Dithmer, said that the new products were all built around a “purpose-driven design,” based on the needs of customers.
“End-user computing is not just about the device any more; it’s about multiple devices, an ecosystem, and a set of solutions that give full functionality for the user, depending on what they want to do,” he said.
Designed primarily for mobile business users, the new Latitude laptops come in a range of sizes, with the E6230, E6330, E6430 and E6530 offering 12.5-inch, 13.3-inch, 14-inch and 15.6-inch screens respectively. All of the models offer up to 32.7 hours Dell Latitude X300 Battery life and multiple connectivity options – including LTE and Bluetooth 4.0.
The Latitude E6430s has many of the same features, but was singled out for its design, pairing a 13.3-inch chassis with a 14-inch HD display. The laptop has a tri-metal casing and is 18% lighter than any comparable product from HP, according to Dell.
Meanwhile, the 14-inch ruggedised Latitude E6430 ATG comes with a handle and is designed for extreme weather conditions – including vibration, dust and high altitudes – while the 14-inch E5430 and 15.6-inch E5530 are aimed at professionals looking for a more budget-friendly mobile platform.
On the desktop side, the new OptiPlex 3010, 7010, 9010 PCs feature wireless connectivity, microphone and headset mini-jacks, and Microsoft Unified Communications certification. They support up to three digital native monitors and up to four front or side USB ports.
Dell latitude d531 battery brand new 4400mAh Only AU $55.08
Finally, the OptiPlex 9010 All-in-One has an 23-inch monitor, integrated power supply, VESA mounting and optional wireless mouse and keyboard.
All of Dell’s new products offer 2GB of memory, integrated graphics and optional 128GB SSD. They also come with version 8 of Intel vPro systems management, to which Dell has added remote BIOS management and remote hard drive wipe.
“The whole concept of bring your own device is very appealing to the end user, but it’s also something that the IT executive has to be very focused on being able to deliver from a cost perspective, a support perspective and a complexity perspective,” said Bryan Jones executive director of Europe public large enterprise marketing at Dell.
“If you look at the products we’re launching today, we’ve embedded a lot of security features and capabilities that really drive that discussion around data sovereignty, data protection and all the things that go along with that.”
Pricing and availability details of the new Latitude and Optiplex models have not been announced.
Leveraging its efficient chip design, Apple says the latest iPad batteries can still run for 10 hours, like the iPad 2, and for nine hours on the 4G LTE cellular network.
Even with a big boost in display resolution, the latest iPad will still have 10 hours of battery life and nine hours on the 4G LTE cellular network.
During the launch of the new iPad, Apple announced a high-definition Retina Display powered by a quad-core A5X chip, along with other features such as an improved camera and high-definition video recording.
The enhanced graphics add a substantial processing load on the iPad and thus demand for battery power, Apple executives said during the launch. But the new iPad will continue to have 10 hours of battery life.
Even on the 4G network, the iPad will have nine hours of Apple A1185 Battery life, which would be a big improvement to many smartphones that don’t last a full day using the cellular network. Apple didn’t elaborate on how it was able to improve the power efficiency of the device, but it’s no doubt rooted in the A5X chip design and how it’s optimised for graphics.

The standard battery lasts about eight hours, which is just enough for the phone to last until the nightly commute home on a normal work day, but when travelling (or even if you forget to charge the phone overnight) that limited battery life is annoying.
We’ve taken a look at three of the latest iPhone battery cases available to discover their pros and cons.
All the cases share some attributes in common: they all charge via a micro USB connector so you won’t be using your iPhone dock cable any more. All the cases come with a micro-USB cord that you can plug into your existing iPhone wall charger. The case and the iPhone battery charge at the same time using the single micro-USB connector.
They all have a dock connector inside the case for your iPhone to plug into, and of course, this connects to the Dell vostro 1510 battery inside the case to keep your smart phone full of juice.
Mophie Juice Pack Air 4
It provides good protection for all sides of the iPhone, with the back fully covered and a protective ridge standing above the edges of the front screen so that if you drop it flat on a pavement the screen won’t make contact.
It has holes in the case to allow direct access to the iPhone’s metal buttons, which makes adjustments easy. The Energizer case, in comparison, makes you press through the silicon case, which requires more effort.
One annoying thing about the Juice Pack Air is that its bright, flashing charging status lights and micro USB charging connector are both at the bottom of the case, so no matter which way you lie it down, your bedroom will be turned into a disco overnight.
There’s a charging on/off switch on the case, which is there to help preserve the life of the battery in the case. Mophie suggests you only switch it to charge when your iPhone is actually low on juice, as the battery case can only be recharged 500 times before its battery will start to fail (and of course, the more often you empty the battery into your iPhone, the more frequently you’ll have to charge the case).
The capacity of the Mobile battery is 1500mAh, which gives a little more than twice the battery life of the iPhone 4′s internal battery, which is rated at 1420mAh.
The Juice Pack Air sells for between $75-$100 at the time of writing.
Padacs PowerCase for iPhone 4
It has holes in the side of the case to allow direct access to the iPhone’s buttons.
The styling of the case is somewhat BlackBerry Torch-esque — gloss black on all sides, with sculpted edges that disguise the heft of the battery. As a result, even the 2200mAh case looks pretty good despite its true bulk.
The fact that the case is sculpted and shiny also makes it the easiest of the three cases to slip in and out of your pocket.
The blue charging indicators are on the back of the case, but unfortunately also on a sculpted part of the case, so even if you lie it flat, it will illuminate your bedroom with a bright, rapidly flashing blue light overnight.
One quibble we had with the case is that by default it does not charge your iPhone — you have to hold down a button on the back of the case for it to start charging. Presumably it has been designed like this so you don’t use the case’s battery unnecessarily for the same reason Mophie puts a switch on its case (see above), but it still feels like the decision has been taken out of your hands a bit.
The other minor downside of the PADACS cases is that the case rim sits flush with the iPhone 4 glass screen, providing very minimal protection for the screen if your drop it hard on its face on an uneven surface like bitumen.
You can buy the PowerCases for $49.95 or $59.95 (depending on capacity) directly from PADACS’ website.
Energizer AP1201 iPhone 4 battery case
The charging indicator for this case is on the back — a series of small, deep blue lights. As a result, if you leave the case on its back overnight, the charging light won’t keep you awake. You can get a read on remaining NOKIA 3310 Mobile Phone Battery life by pressing a small button on one of the corners of the case.
One problem with the Energizer case is that it mostly encloses the phone, so if you want to use the volume buttons on the side or the lock button at the top of the phone, you have to squish them through the silicone, which requires considerably more effort than just pressing the buttons directly. The silent on/off switch is still exposed through a hole, though.
The case also picks up a lot of dust and fluff due to its silicone construction.
Unlike the Padacs or Mophie cases, the Energizer case constantly charges the iPhone — there is no option to turn off its charging to keep the case battery in the best possible condition.
In our testing of these three cases, the clear winner is the PADACS PowerCase. It provides greater HP 484784-001 battery life than any of the other cases, has a shape and texture that makes it super-easy to slip in and out of your pocket, and manages to disguise the bulk of the battery with clever industrial design.

Have you ever run out of battery power on your laptop, notebook, or netbook during a meeting or a class? Sufficient battery life is a persistent challenge for mobile PC users. You can take simple maintenance steps to extend the life of your laptop battery. TheWindows operating system also offers several ways to help maximize the battery life of your mobile computer.
In this article, I’ll introduce some tips that you can use to recharge a battery and extend laptop battery life, and I’ll discuss how to take advantage of Windows settings to manage power more efficiently.
For on-the-go computing, your battery is your best friend. Knowing how it likes to be treated is the first step to keeping both of you happy.
- Keep battery contacts clean. Battery contacts can get dirty or corroded over time, reducing the effective delivery of power. With your mobile PC turned off and unplugged from its external power source, remove the battery. Use a cotton swab dampened with rubbing alcohol to wipe the metal contacts on the battery and inside the device. Allow them to dry completely before reinstalling the battery and reconnecting to a power source. Repeat this procedure every two to three months.
- Charge your battery correctly. When you’re on the road, be sure to carry a power cord and plug your computer in whenever you have the chance. Unlike the older-generation rechargeable batteries like nickel-based (NiMH) batteries (see next paragraph), modern lithium ion batteries can be partially discharged and recharged repeatedly with no harmful effects, but you should avoid fully discharging lithium ion batteries. Consult your owner’s manual for more specific tips on charging, and never use an AC adapter (power cord) or battery charger not approved by your device’s manufacturer.
- Completely drain nickel-based batteries periodically. If you’re using an older laptop (at least three years old) with a nickel-metal hydride (NiMH) battery, be sure to completely drain it and recharge it (every one to three months—consult your owner’s manual) to ensure that it will hold a full charge. (Most newer mobile PCs use lithium ion batteries, which don’t need to be drained to maximize their capacity.) To drain a NiMH battery, simply turn on your computer, unplug it from its external power source, and let the computer run. To speed things up, you could start several applications, turn the screen brightness to its highest level, and ignore all of the great power-saving strategies below. After the power is completely drained, recharge the battery fully. This may take up to 12 hours.
- Cool it. Your mobile computer generates heat, and higher operating temperatures reduce your device’s efficiency, which in turn demands more battery power and can shorten Toshiba satellite pro a120 batterry life. Make sure that your computer can “breathe”: Don’t let clothing, lint, or other obstructions block the cooling vents.
- Carry a spare. Buying an extra battery is a good investment for your peace of mind. Battery prices vary widely. You can significantly increase the power available to you if you’re willing to splurge a little. Contact the manufacturer of your mobile PC to find a replacement laptop battery.
- Store it properly. If you don’t expect to use your mobile computer for a week or more, it’s a good idea to store the battery, discharged to about 40 percent of full capacity, in a cool place. Click the battery status icon in the notification area of the Windows taskbar to check the current charge. Avoid storing a fully discharged—or fully charged—lithium ion battery for extended periods, as this can diminish battery life.
Optimize your power settings
The display and hard disk on your mobile PC are the two biggest consumers of battery power. By choosing a power plan (called a power scheme in Windows XP) you can extend your battery life by automatically lowering screen brightness and reducing other power-hungry functions. A power plan is a collection of hardware and system settings that control how your mobile PC manages power.
You can also create a custom power scheme to suit your specific needs. You can create as many custom power schemes as you want.
Take advantage of low-power states
The different versions of Windows provide the following battery-saving states:
- Windows 7. Sleep and hibernation (which is like deep sleep)
- Windows Vista. Sleep and hybrid sleep (which is a combination of sleep and hibernation)
- Windows XP. Standby (which is like sleep) and hibernation (which is like deep sleep)
In a sleep state (standby), your display and hard disk turn off, and all open programs and files are saved in random access memory (RAM)—your computer’s temporary memory—rather than to the hard disk. Information stored in RAM is cleared when the computer turns off, so it’s a good idea to save your work before placing your system in sleep or standby mode. Otherwise you may lose data if you lose power or swap batteries or if your system crashes.
Sleep (standby) is particularly useful when you’re using your mobile PC intermittently during the day. For example, when driving between clients’ offices, put your computer to sleep or on standby to maximize the life of your Acer As07b31 laptop battery and to maintain quick access to open programs, files, and documents. When you want to use your computer again, it wakes up quickly, and your desktop is restored exactly as you left it.
In hibernation, your computer saves everything to your hard disk and then shuts down. When you restart the computer, your desktop is restored exactly as you left it. Hibernation uses less power than the sleep state (standby), but it takes a bit longer to resume.
Hybrid sleep is a power-saving feature designed primarily for desktop computers. Hybrid sleep saves any open documents and programs to random access memory and to your hard disk and then puts your computer into a low-power state.
Adjust screen brightness
You can also conserve battery power by reducing the screen brightness. To adjust your screen brightness, refer to the instructions from your mobile PC manufacturer. Every computer is slightly different, but you can usually use a combination of keys, a function key, or a software tool to dim the screen.
Even better than dimming the screen is blanking it completely when you’re not using your computer. You can further minimize power consumption by reducing the amount of time the computer is idle before the screen goes blank. The power schemes and power plans in Windows let you adjust your power settings to turn off the display after as little as one minute of inactivity. In addition, a number of third-party software developers offer free applications that enable you to turn the display off and on at will.
Turn off wireless
Another significant drain on your battery power is your wireless card. You should turn off your wireless device when you’re using your mobile PC but are not connected to a wireless network. You can either remove your Wi-Fi card or press the manual hardware button (or switch) on your computer, if you’re using a Centrino-based mobile PC. Refer to the instructions from your mobile PC manufacturer to learn where the manual hardware button is. Other computers may require that you turn off the wireless connection using software settings. Again, consult your instruction manual for details.
Additional power-saving tips
In addition to adjusting power settings to maximize battery life, consider the following tips to minimize power consumption when you’re away from electrical outlets.
- Turn off scheduled tasks. If you use scheduled tasks to run programs or scripts, or if you schedule other tasks to occur automatically at a preset time, specify that these tasks won’t be performed when the computer is running on battery power.
- Keep the use of tools in the notification bar to a minimum. Try to minimize your central processing unit (CPU) usage. Look at the notification area of the taskbar and close any tools (or utilities) that are not necessary. Often, these tools are installed on the computer when you first receive it. Windows 7 users can also click the up arrow at the end of the notification area to see tools and utilities that are hidden but available. The notification bar, shown below, is on the bottom right of your computer desktop.
- Limit power-intensive activities. Avoid watching a DVD, listening to a CD, or playing online games on your mobile PC when you need to conserve battery power.
- Add memory. You can minimize the reliance of Windows on virtual memory and reduce power consumption by adding memory (RAM) to your laptop computer.
By adjusting your mobile PC settings to conserve battery power and by implementing these tips, you can relieve the stress and inconvenience of running out of battery power.
The very sturdy Dell Latitude XT3 is an enterprise-class laptop that comes with a twist: You can quickly fold it into a tablet PC by rotating its screen on its single central hinge. Such so-called convertible PCs often land in large organizations, including those in the health care, education, and law enforcement fields. This kind of machine needs to perform well both as a laptop and as a tablet, hold up well in hectic environments, and deliver good battery life. For the most part, Dell’s third-generation Latitude XT fits the bill nicely.
The hefty but attractive midlevel model I tested sells for an equally hefty $3003 (as of April 12, 2012). The moment I picked up the XT3, I knew that it was made to take some knocks. The case is constructed of thick, stiff plastic with magnesium-alloy reinforced corners. I found almost no flex in the PC case or the display panel. Dell claims that it made the XT3 spill-resistant; I didn’t test that, but the thin rubber gaskets that line the keyboard, the screen bezel, and the perimeter of the computer’s top panel are reassuring.
My main rap on the XT3: It weighs too much. With the internal nine-cell internal battery pack, this convertible laptop weighs 5.2 pounds–not something you’ll want to hold in the crook of your arm for long. Its accessories bump the total travel weight to 6.7 pounds, making this portable a tough sell to road warriors. On the upside, the batteries just won’t quit. The internal pack lasted for 8 hours, 23 minutes in lab tests, 3 hours longer than the average all-purpose laptop. When we popped on the optional nine-cell slice ($199), it pumped battery life up to a marathon 19 hours, 46 minutes. However, that extra pack raises the total weight to 8.1 pounds. I’d hate to have to hoist the XT3 up into overhead baggage compartments on a regular basis, but I could easily shuttle it around the office between cubicles and meeting rooms.
The XT3 is very smooth to use, with few snags. The 13.3-inch multitouch capacitive screen is a pleasure to view and tap on. Even though it’s smaller than many all-purpose laptop screens, it offers a decent 1366-by-768-pixel resolution, and I could read text on it even in bright light. The keyboard comes with the usual Chiclet-style keys, but they’re very crisp and comfortable to type on. As for pointing devices, you get both an eraserhead pointer nested in the middle of the keyboard and a touchpad. I have two nitpicks: It’s too easy to hit the Page Up and Page Down keys accidentally, and the hypersensitive eraserhead pointer sends the cursor dashing off in all directions. I stick with the touchpad, which works fine.
In tablet mode, the screen responds nimbly to finger touches. Brushing to scroll documents, pinching and unpinching documents to shrink and expand them…it all works quickly and effortlessly. The stylus works very well, but not perfectly. I had no trouble tapping menu items with it, but I started wishing for a little more screen stickiness during my inking test – the stylus glides a tad too easily. If you need to navigate the screen while wearing gloves, Dell offers a resistive touchscreen option.
One notable issue: When I rotate and lay the screen down on the keyboard, whether I’m closing the laptop or folding it into a tablet, the panel doesn’t easily lock into place. I often have to fiddle with the panel to get it to latch, and I don’t hear that reassuring click.
You pay a big premium for the XT3′s toughness and its dual laptop-tablet nature. On our WorldBench 7 test suite, this PC posted a score of 108, in line with its mostly midrange silicon (an Intel Core i5-2520M dual-core processor, 4GB of DDR3 memory, and a 128GB solid-state drive). You can buy as much oomph on some ultraportables costing under $1000. Our test results confirm that the XT3 is geared more for work than play: Although the XT3 cranked through image editing and video and audio encoding, gamers need not apply. This PC uses Intel’s HD Graphics 3000 chipset, handling games well only at low detail and resolutions. You can upgrade to a Core i7 dual-core processor and 8GB of memory for another $295.
The audio from the internal stereo speakers sounds exceptionally clean and vibrant. Bass is weak – typical for small speakers – but they don’t sound tinny. The webcam, embedded in the screen’s top panel between the array microphones, records remarkably sharp video at its maximum 1280-by-720-pixel resolution, and you get lots of controls to adjust the recording levels, including gamma. The array mics clearly recorded my voice even when I stood 6 feet away. The XT3 makes an excellent station for conducting VoIP calls, such as over Skype.
Typical of enterprise PCs, the XT3 comes loaded with slots and ports, offering extra security options (such as SmartCard access and an optional fingerprint reader) and ensuring broad compatibility with different site installations. The XT3 comes with three dedicated USB ports plus a combo USB/eSATA port. My main beef: The USB ports max out at 2.0. For video, you get VGA and HDMI ports, but no DisplayPort. Other slots and ports include those for a 34mm ExpressCard, SD Card or MultiMediaCard, FireWire, and a headset.
Calibrate Battery On Android Devices With Battery Calibration
Experienced ROM flashers of Android devices will be quite familiar with the concept of clearing the battery stats every time in order to calibrate the HP probook 4510s replacement battery. This is mostly needed when a new ROM is flashed with the battery at less then 100 percent. Earlier, we covered the manual method on how to fix the battery drain issue on rooted Android devices, but this manual re-calibration can be quite cumbersome depending on your device type as it requires you to boot into recovery mode, and more. Not anymore, thanks to XDA-Developers forum member marosige, who has come up with an app named, Battery Calibration. This app allows you to clear those battery stats rather more conveniently through a simple user interface. Read on for more on this app and to download it.
Now, the question many would be asking is, “What’s the advantage of using this app over clearing battery stats from recovery and then fully charging and discharging your phone?”. The answer is a threefold one.
- This app first of all, eliminates the need to boot into recovery and rocking a few hardware keys.
- Secondly, the app will only let you delete the battery stats when and only the battery is charged at 100 percent, thereby eliminating any false calibration that may or may not occur when going through recovery.
- That said, this app can be really handy for users with stock recoveries but rooted devices where you can’t clear the battery stats via recovery. This app will still allow you to do that.
But one thing this app will not do for you is discharge the phone completely and then charge back to 100 percent. Yes, in order to truly calibrate your Dell inspiron 1545 battery, you will have to do that manually. There is no automated way out of that for now.
You can see below a few screenshots of the very simple interface that only requires you to hit the Battery Calibration button once the phone is charged at 100 percent. The app shows you the current battery level as well for convenience.
