WiFi Napping – An Adorable Way To Double Mobile Phone Battery Life

Way To Double Cell Phone Battery Life WiFi Napping   An Adorable Way To Double Mobile Phone Battery LifeA Duke University student named Justin Manweiler has created a way to extend the battery life of mobile devices by making changes to WiFi technology. He calls it “SleepWell.”

The more wireless devices there are in a space, the higher the drain is on each one’s mobile phone battery as they access the internet. Downloading a movie in a city uses more battery power than downloading a movie in a rural area over a public WiFi network.

Manweiler’s system embraces this — when your WiFi-enabled device is in standby and it detects other WiFi devices that are actively using the network, it puts its connection to sleep. This saves battery life both for your own device and for the one using the connection.

Nokia unveils Symbian Belle-powered smart phones

Nokia has showcased an update for its Symbian platform, along with three soon-to-land handsets running the operating system.

Dubbed Symbian Belle, the revamped OS boosts the number of homescreens available on a phone from three to six to allow users more space to store apps, as well as providing more scope to customise their layouts with new, different sized live widgets.

Nokia has also added an Android-style pull down menu and taskbar to access notifications from any of the home screens. And perhaps most excitingly, it has brought Near Field Communications (NFC) tech to the phones for the first time to enable Nokia phone owners to use their handsets to pay for low ticket items by swiping them over a reader.

Contacts, videos and images can also now be shared with other NFC-enabled devices too and there’s the option to unlock new content in games by touching two Symbian Belle devices together.

Heading Nokia’s Symbian Belle charge are three handsets, dubbed the 600, 700 and 701.

Billed as Nokia’s smallest-ever smartphone with dimensions of 110 x 50.7 x 9.7mm, the 700 teams a 1GHz processor with a 3.2 inch AMOLED screen ClearBlack display, expandable memory of up to 32GB via microSD card support and a five-megapixel camera.

Toshiba pa3331u-1bas battery – Brand New 4400mAh Only AU $59.71

Despite the similarity of their titles, the 701 is a real step up. Features include an eight-megapixel camera, secondary snapper for video calls and a 3.5-inch touchscreen that Nokia claims is the “brightest-ever mobile phone display”.

And completing the triumvirate is the 600. Designed for music fans, this is Nokia’s loudest phone so far and offers the option to stream music wirelessly to NFC-enabled accessories. It’s also home to a five-megapixel camera and a 1GHz processor and will be available at a lower price point to the 700 and 701.

Battery extenders for HTC, Samsung, Blackberry smart phones

powerskins battery extenders batteries company.com  300x167 Battery extenders for HTC, Samsung, Blackberry smart phonesBattery cases are no longer the exclusive domain of iPhones, as Android-based phones ramp up in popularity.

One of the most annoying aspects of travelling is running out of battery on your smartphone just when you really need it — when checking emails just after getting off a long flight, or trying to access maps in a foreign city.

iPhone users have had a good range of options to bump up their battery life, but there haven’t been any for people getting inadequate battery life from handsets like the HTC Desire HD, Samsung Galaxy S2, Google Nexus S or BlackBerry.

A new range of smartphone battery skins from XPAL is now addressing that gap in the marketplace.

XPAL says it is tackling the challenge of making battery cases for a broader range of handsets head-on, even though Android/BlackBerry/Windows Phone 7 handsets often have a shelf life of less than six months.

Currently, XPAL has cases available for:

  • HTC HD7
  • HTC HD2
  • Samsung Galaxy i9000 / i9003
  • HTC Desire HD
  • Samsung i9020T
  • Google Nexus S
  • BlackBerry 8520

Above: a PowerSkin on an HTC Desire HD.

The PowerSkins all have a capacity of between 1200mAh and 1620mAh, depending on the phone model, which means that they deliver roughly the battery life of the handset’s inbuilt battery again.

Because charging the handset’s inbuilt battery too often can wear it out prematurely, PowerSkins also come with an on/off switch so you can decide when to start giving your handset additional juice — the best strategy is usually to only do so when the handset’s inbuilt laptop battery is about to run out.

Lithium-Ion Batteries Market Set for Boom Courtesy of Hybrid and Electric Vehicles

batteries1 Lithium Ion Batteries Market Set for Boom Courtesy of Hybrid and Electric VehiclesDriven by plunging prices and accelerating demand from the electric and hybrid automobile market, lithium-ion will emerge as the world’s leading rechargeable battery technology and achieve 350 percent revenue growth from 2010 to 2020, according to a new IHS iSuppli Rechargeable Batteries Special Report from information and analysis provider IHS (NYSE: IHS).

Global lithium-ion battery revenue is expected to expand to $53.7 billion in 2020, up from $11.8 billion in 2010, as presented in the figure below. Revenue will rise to $31.4 billion in 2015, allowing lithium-ion to surpass the current dominant rechargeable battery technology, lead acid.r banner2 Lithium Ion Batteries Market Set for Boom Courtesy of Hybrid and Electric VehiclesWhile lithium-ion will find wide usage in mobile electronics products such as cellphones and notebook PCs, usage in cars will fuel the bulk of sales growth.

“Lithium-ion at present is much more expensive than alternative technologies, costing two to three times as much as sodium-sulfur, lead-acid and nickel-metal-hydride rechargeable batteries,” said Satoru Oyama, principal analyst of Japan electronics research for IHS. “However, lithium-ion pricing will decline much more rapidly than the other technologies, coming close to cost parity in 2015, and then becoming the least expensive type of rechargeable battery in 2020. Combined with the inherent advantages of the technology, the increasingly competitive cost of lithium-ion will cause car makers to employ it as their battery technology of choice in future electric and hybrid vehicles.”

Lithium: Just What the Doctor Ordered for Automotive

Lithium-ion delivers several enhancements compared to other rechargeable battery technologies.

These advantages include more flexible form factors and lighter weight. Furthermore, lithium-ion devices have no memory effect, meaning they maintain their full capacity even after a partial recharge. Finally, lithium-ion laptop batteries are considered to be more environmentally safe than other technologies.

These features make lithium-ion particularly attractive for electric vehicles, hybrid electric vehicles and plug-in hybrid electric vehicles.

Because of this, the automotive segment will be the leading market for lithium-ion batteries by 2015, surpassing the current top application, notebook PCs.

Lithium’s Elements of Success in Electric and Hybrid Cars

The dominant battery technology used in hybrid cars now is nickel-metal-hydride. More than 1 million hybrids with nickel-metal-hydride batteries were shipped in 2010, led by the Toyota Prius.

However, shipments of nickel-metal-hydride batteries to the hybrid market will not grow in the future as the use of lithium-ion begins to take off.

One concern regarding the use of first-generation lithium-ion batteries in cars is safety. There can be a risk of fire using existing lithium-ion battery materials due to the high temperatures involved. There have been documented incidents of lithium-ion battery fires in smaller devices, such as PCs and mobile phones.

To achieve acceptable safety levels for hybrid and electric vehicle batteries, lithium-ion battery makers must take steps to prevent internal short circuits which can cause external damage. These steps include improving control of power generation during discharges and enhancing the management of rapid charging.

While automotive will be the dominant market for lithium-ion batteries, notebook PCs and cellphones will remain major markets for the technology, accounting for $12.3 billion in revenue in 2010, up from $7.8 billion in 2010.

Other major uses for lithium-ion batteries include use in solar power systems, smart electricity grids and electric tools.

Battery Breakthrough Could Revolutionize Mobile Computing

Battery Breakthrough Could Revolutionize Mobile Computing batteries company.com  Battery Breakthrough Could Revolutionize Mobile ComputingResearchers at Stanford University have just made a major breakthroughthat may impact the technology industry for years to come: they’ve built a better battery. The project, an attempt to use lithium-sulfur in place of the lithium-ion technology that is used in batteries today, has been in development since 2007. Recently, the scientists’ efforts were rewarded when they created a battery that lasts four times as long as its lithium-ion counterparts while also having the benefit of being “significantly safer” than today’s batteries which occasionally explode after short-circuiting.

Although still a ways off from commercial viability (and availability), the lithium-sulfur batteries promise advances like 80% more capacity, 10 times the power density and, theoretically, the ability to last four times as long as modern batteries.

The new battery technology represents the final step in our quest for always-on connectivity to the mobile web. We already have Wi-Fi hotspots, 3G and 4G networks for Internet everywhere and a host of mobile gadgets from netbooks to iPads and mobile phones to notebook computers. But what we haven’t had yet is a way to keep our gadgets powered up for more than a day or so without a charge. That may be soon about to change.

An Always-On Mobile Web

With these sorts of improvements, lithium-sulfur batteries could lead the way in the next phase of the mobile revolution. They could allow us to fully enjoy the web from anywhere in the world, without having to worry about dying batteries, access to power outlets or having to carry around replacement battery when planning long-lasting mobile computing sessions.

battery%20tech Battery Breakthrough Could Revolutionize Mobile Computing

Far more than just a convenience, better battery technology would impact how our mobile devices are designed and how they behave. For example, Apple currently imposes numerous restrictions on members of their mobile device lineup for the sake of battery performance. On Apple iPhones, iPod Touches and the forthcoming iPad, applications aren’t permitted to run in the background and Adobe Flash technology has been banned altogether, supposedly for its CPU usage which rapidly drains battery juice. Other mobile smartphone makers, while not necessarily as restrictive as Apple, still have to weigh the benefits of providing these same types of features with the performance hit their gadgets will take if they do so. And as anyone who regularly fires up their smartphone web browser knows, too much Internet surfing during the day means a phone that dies out before nightfall.

bn nook logo oct09 Battery Breakthrough Could Revolutionize Mobile ComputingAnother example of the technology’s potential impact: e-Readers. Today, if you want to pack your Kindle or Nook device to take with you on vacation, you still have to go through the thought process: how long will I be gone? Will my battery last? Should I pack the cord? Now imagine that you could just throw your e-Reader into your bag without a second thought, just as if you were packing the paperback novel or newspaper these sorts of gadgets aim to replace. Would that encourage more people to make the switch from the analog formats to digital?

The Impacts of Better Laptop Batteries

What if, in the future, concerns like these were no longer a worry? What if phones, netbooks, e-Readers and other mobile devices could be used for days on end without the need for a charge? That would radically impact the way we think about and use our mobile devices.

There are a million other use cases that could benefit from this technology change, too, including sensor networks, computing from remote areas, faster news dissemination from areas impacted by disasters (either natural or man-made) where power outages have occurred, gadgets for hikers, campers and other explorers who spend weeks away from civilization and, therefore, away from electricity, mobile location-based services that run in the background on smartphones and other personal mobile gadgets and – OK, we’ll admit it – the ability to Twitter all day long without a recharge.

For the nitty gritty technical details about this new battery technology, MIT’s Technology Review explains everything from the cathodes to the conductivity as well as the challenges still ahead for this breakthrough technology. Most notably, the scientists still need to figure out how to maintain capacity. After five discharge/recharge cycles, the batteries lost one-third of their initial storage capacity and after 40 to 50 cycles, they ceased to function altogether. However, if the researchers can overcome that final hurdle and a few others, the new technology could one day become commercially viable. It’s too soon to know if that will actually occur, but as gadget lovers ourselves, we’re hopeful.

Top 10 smartphone facts you may not know

What role does a Viking king have in the evolution of smartphones? What’s the connection between Samurais and iDesigner Jony Ive? And what’s so fruity about BlackBerrys? Check out top ten rundown of telecoms trivia to find out.

1 BlackBerrys were almost called Strawberries

blackberry bold 9900 official 520x300x24 fill Top 10 smartphone facts you may not know

A marketeer at Research In Motion initially wanted to call the company’s iconic business blowers ‘strawberries’. The thinking was that the physical QWERTY keyboards they feature reminded him of the seeds you find in the summer fruit.

He was overruled by his boss, though, who favoured ‘BlackBerry’ because the alliteration meant it had more of a ring to it. It’s hard to argue with him.

2 Microsoft’s Kin sold just 500 units

microsoft kin phones 520x300x24 fill Top 10 smartphone facts you may not know

The Kin was launched in a blizzard of hype. But in the face of mass indifference from consumers, Microsoft pulled its social networking focussed Kin phones from the market after just six weeks. In that time a trifling 500 units were sold.

Of all the handsets once touted as iPhone killers (an ignominious list that also takes in the Palm Pre and the Nokia N8), none fell as short as the Kin.

3 The first mobile phone call was in 1973

One afternoon in 1973, Motorola General Manager Martin Cooper took to the streets of New York with a prototype mobile phone. It was a monolithic device that snaps reveal was every bit as obelisk-like as you’d expect.

But it worked well enough for Cooper to make a call. And what a call. The first number he rang was Dr Joel S Engel of Bell Labs phone company. When Engel, who was head of research at Moto’s deadly rival, picked up, Cooper was delighted to be able to inform him that Moto had beaten them to the punch with the first functional mobile phone.

4 Cameraphones in Japan & Korea must make a shutter sound by law

camera illustration 520x300x24 fill Top 10 smartphone facts you may not know

The rise of voyeuristic photography in Japan and Asia was an unwelcome side effect of the boom in cameraphone ownership. It’s now such a problem that handset makers are now legally bound to make handsets that do not allow users to turn off the shutter sound.

5 Bluetooth was named after a Viking King

viking warrior 520x300x24 fill Top 10 smartphone facts you may not know

Bluetooth technology, which enables smartphone owners to swap data wirelessly, landed in smartphones back in 2000 with Ericsson’s T36. But the name ‘Bluetooth’ goes much, much further back.

The tech, which was developed jointly by Scandinavian tech giants Ericsson and Nokia, takes its name from King Harald Bluetooth of Norway. Unlike other potentates of the 10th century, the Danish king favoured negotiation with his foes over bloodletting. And it’s for that propensity to talk first and fight later that his name was chosen for the communications technology.

6 ‘App store’ was patented by Sage Networks back in 1988

app store business 520x300x24 fill Top 10 smartphone facts you may not know

Patent battles are ten-a-penny in the tech sector right now. But few are as intriguing as the ongoing spat between Apple and Amazon over the latter’s use of the term ‘app store’ for its Android applications market.

In fact, the phrase ‘app store’ was originally coined in 1998 by Sage Networks. And a cursory look at its patent filing reveals that it was thinking along similar lines to Apple way back then. Not least in the way that the application details plans for a service to host computer software applications over a global computer information network. Sound familiar? It gets even more uncanny later on, when we’re informed it planned to allow “multiple users to rent software applications developed by applicant or third parties”.

Alas, although Sage was granted the patent, it didn’t complete the final stage needed for it to be binding. In 2002, a rebranded Sage, now in the hands of new owners, attempted to reapply for it and was rejected out of hand.

7 Nokia phones’ tone for receiving texts is Morse Code

text illustration 520x300x24 fill Top 10 smartphone facts you may not know

Or to be more specific, it’s Morse Code for the letters ‘SMS’. That’s ‘short messaging service’ to you and me.

8 Nokia once claimed there was no market for touchscreen phones

 Top 10 smartphone facts you may not know

Back in 2006, Nokia bestrode the mobile phone world. But if you cared to look close enough, the seeds of its decline were already in evidence. Nowhere was that more evident than a survey it conducted into sector trends.

According to Nok Nok, poll participants had left them in little doubt there was ‘no market for touchscreen phones”. So for its Nseries phones it retained physical QWERTY keyboards in keeping with their billing as pocket PCs.

A year later, the touchscreen-toting first iPhone appeared. And as the world went for the tech in a big way, Nokia was left floundering. As Apple and Android eat away at its market share month by month, the company’s movers and shakers must rue their “faster horse” moment more each day.

9 HTC stands for High Tech Computer Corporation

htc logo large 520x300x24 fill Top 10 smartphone facts you may not know

As anyone who knows phones will tell you, HTC wasn’t always the fun consumer brand it is now. For aeons, their functional phones were the sole preserve of geeks and technocrats.

But while the gadget-maker’s MO has changed, in the form of the moniker ‘High Tech Computer Corporation’ (HTC) it’s stuck with a name every bit a sawdust-dry as its handset offerings once were. Although in a funny kind of way, we actually think that it’s meta-boringness almost makes it cool.

10 iPhone takes its cues from samurai swords

 Top 10 smartphone facts you may not know

Apple design doyenne Jonathan Ive is Apple’s not so secret weapon in the smartphone wars. And his weapon of choice is the samurai sword.

Or at least, it’s an inspiration. In search of an insight into ensuring his products stay light while retaining an integral toughness, Ive once travelled to Japan to see how the sword-creating craftsmen have been forging the blades since time immemorial.

The purpose? To see metal pushed to its absolute limit. The sword makers are experts in creating blades with soft, light inner layers while ensuring the outer, business end is super sharp and robust. It’s a process that involves folding and re-folding steel over and over again and is a tradition that’s been handed down for centuries.

How far the techniques he’ll have learnt in the Land of the Rising Sun actually feed into Ive’s drive to create ever-thinner-but-robust kit is hard to quantify. But given the man’s meticulous attention to detail, you can be sure that the experience will have fed in somehow.

Sony new Vaio SA and SB-series with docking stations and battery slices

Sony is equipping its new Vaio SA-series and SB-series with docking stations and battery slices. The laptop battery life is going to double, and the annoying plugging in of power cables will be a thing of the past.
Sony laptop battery Sony new Vaio SA and SB series with docking stations and battery slicesSony Vaio VPC-SB1Z9EB with Battery Slice VGP-BPSC24 on the Docking Station VGP-PRS20

Who hasn’t stared jealously at the extensive docking and battery options available for the business class models from HP, Lenovo or Dell? Now Vaio users can profit from these features too. The mainstream consumer series, Vaio SA and SB, come with docking stations and battery slices, granting the user the ultimate battery life experience.

Docking Station VGP-PRS20

The docking station, VGP-PRS20 (about 129 Euros), uses a power adapter cable which is similar to that of the notebook (mixing the two up won’t cause any problems). As the user will have two power cables which serve the same purpose, he/she can leave the cable of the docking station plugged in during a trip for simplicity sake. The docking station can be used to recharge batteries (including the battery slice) and the slider on the right side allows the user to switch to “Extended Laptop Battery” mode.

The docking port offers HDMI, VGA, 4 USB ports (no USB 3.0; those are only available on the notebooks themselves) and 2 x RJ45 (LAN) ports. As soon as the Vaio is placed on the docking port, the HDMI, VGA and RJ45 ports of the laptop can no longer be used, and to prevent anyone from doing so, the docking station has two plastic flaps on the side which block these ports effectively.

The placement of the device does not involve the use of any latches or locks. This means: place the laptop on the two protruding bumps and you’re done. The subnotebook will not slip due to two securing hooks (silver) which stick out of the base unit and secure the model so that it doesn’t fall.

Battery Slice VGP-BPSC24

The VGP-BPSC24 battery slice is a flat battery (Li-Polymer, 6 cell), which fits under the base unit of the Vaio SA- and SB series models. It has a capacity of 4.400 mAh or 49 Wh (11.1V). The notebooks have have a connector on the bottom which allows them to attach themselves to the slice battery. However, this connector is not the same as the one found on the docking port. This additional battery slice VGP-BPSC24 costs around 130 Euros and weighs 520 grams.

During notebook use, the laptop batteries are designed in such a way that the slice battery will be used first. The slice battery can be charged via the notebook or  through a small charging dongle (while the battery is not connected), so theoretically, the 13.3 inch device can run the entire day without internet.

The black battery slice looks good when attached to the notebook, even though its colour only fits to that of the black Vaio SB. The latch has two metal hooks on the locking side. The holes for these hooks, on the other side, are made of synthetic material. To prevent an accidental unlocking, the security mechanism is two-fold (lock and release). The perpendicular hole in the middle of the slice battery is for the docking station (without this hole, the slice HP COMPAQ Business Notebook NC6400 Battery would raise the laptop enough to free the non-functioning ports).

For our test we used the series model VPC-SB1S1E/W with an i5-2410M processor. This model comes with a 50 Wh battery (4.540 mAh). We dimmed the brightness to roughly 100 cd/m² during our test. The CPU load was low while surfing on the web (no videos, only websites). One downside is that the charging of the duo packet (notebook battery + battery slice) takes a while: 5:46 hours.

WLAN-Test @50 Wh + 49 Wh: 648 minutes (10:48h)

Thanks to the docking station and battery slice, the user is spared the chaos of  cables all over the place, and the mobility is doubled. These two additional features are fully compatible with each other, which means that the Vaio notebook can still sit on the docking station, even if the slice battery is attached. These features are sure to immensely increase the comfort of the user, as both the Vaio SA (not available yet) and the Vaio SB can connect within one second to these peripheral devices.

How To Maximize Battery Life Of HTC Thunderbolt

thunderbolt battery life batteries company.com  How To Maximize Battery Life Of HTC ThunderboltEven though the HTC Thunderbolt didn’t make our longest-lasting smartphones list, that doesn’t mean owners have to settle for short battery life. It is possible to squeeze all-day power out of the phone. We’ve found a slew of simple things you can do to get more hours off the charger without making your phone pointless as a mobile computing device (that don’t involve a bulky battery).

Remember, the HTC EVO 4G had some longevity issues, too, and we suggested you check out these tips over at Good and Evo (25+ at last count) to make it last longer. Several of these apply to the Thunderbolt as well. The forum-goers over at Android Central have a monster thread about the topic. And, of course, we have our own (general) battery tips for Android phones. After mining these tips for my own Thunderbolt, I’ve been able to get 12 – 16 hours on a regular basis.

Here are the tips:

  • I lowered my default screen brightness to 25%. Your needs may vary, especially if you spend more time outdoors.
  • I leave my WiFi radio on constantly. This doesn’t drain much battery when it’s not within range of a network it knows and isn’t constantly searching for networks to connect to because I disabled WiFi notifications. This keeps the phone from updating me every time a network comes in range, which is every 3 feet in NYC. By leaving the WiFi on, I don’t have to remember to connect to a network when I’m at home or work or other places I frequent. This saves a lot of battery power.
  • I also changed the WiFi sleep policy to Never so that the phone uses WiFi (when connected) even if the screen is off.
  • I disabled Always On mobile data. All of my services still sync just fine. Background Data is still on.
  • I disabled data roaming. Most of the time I’m in a normal service area.
  • I usually turn off my screen when I don’t need it out of habit, so my screen timeout time is long — 5 minutes. However, if you tend to just leave your phone off to the side when you’re done, set this lower.
  • I’ve turned off auto-sync for services I don’t use (News, Stocks) and upped the sync interval for apps and services I don’t check very often. Be sure to go into individual apps that sync data to do this as well.
  • Every now and then I poke my head into Settings > About Phone > Battery > Battery Level to see what’s using the most power. Sometimes it’s a system setting or component, but sometimes it’s an app updating too frequently. Then I can adjust.
  • The only home screen widget I use is the HTC clock/weather app. I deleted FriendStream first thing.
  • I disabled “Movie Updates” in the BlockBuster app.

I didn’t condition or bump charge my battery, though that’s a step I might take in the future depending on how badly this battery degrades over time.

Anyway, this is just 10 things out of around 30 tips all told. I’m not sacrificing any functionality I desire, I’m getting all the data I need/want in a timely manner, and I have all-day battery life. Win. Check the sources for more tips to see which ones you can deploy to add some life to your Thunderbolt. And if you have any new battery usage tips, let us know in the comments!
