\n<\/a>Simple question \u2013 how\u2019s your battery life<\/a> under iOS 4? We keep wanting better hardware and more features \u2014 and better battery life at the same time. How did iOS 4 deliver for you?<\/p>\n

If the answer is not too well, we\u2019ve got some steps you can use to try and help. We did this last year for iPhone<\/a> 3.0, and it\u2019s worth doing again.<\/p>\n

Now, if your battery<\/a> drain is caused simply by use \u2014 you\u2019re running background music or navigation like a fiend, for example, your only choice is to get a few more charging cables or battery extenders<\/a>. If, however, you\u2019re doing roughly the same things you\u2019ve always done and getting substantially less battery life for your troubles, there\u2019s a chance a few troubleshooting steps might just help get your power problems back under control.<\/p>\n

Reboot iPhone<\/h3>\n

If, all of a sudden, your iPhone starts burning through Dell Inspiron 1300<\/strong> Laptop Battery<\/a> and getting hot at the same time, there could be a \u201crogue process\u201d just churning away in the background. The answer to that is a good old-fashioned power cycle.<\/p>\n

Hold down the sleep button until the red \u201cSlide to power off\u201d arrow appears. If your iPhone is frozen or otherwise in dire straights, you can hold down the home button at the same time as the sleep button to force quit all applications and bring up the red arrow. Then just swipe, let the iPhone turn off, wait a few seconds, and hold down the sleep button again to turn your iPhone back on.<\/p>\n

Redo Push<\/h3>\n

Since iPhone 2.0 we\u2019ve seen Push gone wrong really cause a hit to HP 441425-001<\/strong> Battery<\/a> life. With 3.0, Push Notification means not only could mail, calendar, and contacts start misbehaving in the background, but your IM, Twitter, games, and all sorts of other apps can as well. In iOS 4 we can even have multiple ActiveSync accounts so push can hit twice as hard.<\/p>\n

Apple<\/a> says Push can cause a 20% drop in battery life, but if you think yours is worse then it should be, the next step is to redo anything that involves Push, including MobileMe, Exchange, and Google Sync accounts, and apps using Push Notification. Now, you might want to try doing one at a time, check your battery life, and if you don\u2019t notice any improvement, try the next one. If you find the culprit quickly, that approach could save you some time. If you just want to get it over with, you might want to do them all at once.<\/p>\n

For the accounts, go to Settings > Mail, Contacts, Calendars, choose your MobileMe and\/or Exchange accounts, scroll down to the bottom and hit delete<\/em>. For apps<\/a>, go to Settings > Notifications and look at the list of any apps using Push Notification. Go back to the Home Screen, hold down the home button until the icons start to jiggle, and delete the Push Notification app.<\/p>\n

Then, for accounts, go back to Settings > Mail, Contacts, Calendars, hit Add Account\u2026, choose Mobile Me and\/or Exchange, and re-enter your settings. For Push Notification apps, either sync them back from iTunes or go to the App Store app and re-download them.<\/p>\n

My 3GS was getting warm and draining fast after I added Google Sync. Once I deleted and added it again, everything was great. So don\u2019t skip this step.<\/p>\n

Restore as New iPhone<\/h3>\n

We won\u2019t lie to you \u2014 this is the nuclear option. It\u2019s scorched earth. But to be frank, we at TiPb almost always<\/em> default to this step because it almost always<\/em> \u201cjust works\u201d. We do this every time we get a new firmware and every time we notice something just isn\u2019t right, and we have excellent battery life<\/a> to prove it.<\/p>\n

To restore your iPhone as new and get a fresh, clean start, attach it to your Windows or Mac machine via the USB cable and launch iTunes. A Restore button should be front and center on the screen. Hit it, then wait as iTunes goes through the laborious process of wiping your iPhone and installing the firmware again from scratch.<\/p>\n

IMPORTANT: When iTunes asks if you want to restore your data from backup or set up as a new iPhone, choose NEW iPHONE.<\/p>\n

Yes, you will lose your settings and any data saved in apps that don\u2019t provide some sort of sync functionality, but it\u2019s possible (even likely) some corruption in those settings or data is contributing to your poor Toshiba PA3166U-1BRS<\/strong> Battery<\/a> life, and with an appliance like the iPhone, this is the only way to get rid of it.<\/p>\n

This will also kill your Jailbreak, if you\u2019re jailbroken. But if something in your Jailbreak was killing your battery life, like backgrounder gone awry, trying out your iPhone without the Jailbreak is a good way to establish that.<\/p>\n

Once your iPhone is set up as new, you can sync your info and media back over using the iTunes tabs as normal, and\/or setup accounts and download apps on the iPhone itself.<\/p>\n

Conclusion<\/h3>\n

iOS 4 should give you around the same battery life as previous versions. Even multitasking on iPhone 3GS shouldn\u2019t be a huge hit given Apple\u2019s implementation. If you\u2019re getting substantially less, there could be a problem with your setup or install.<\/p>\n

Rebooting the iPhone, redoing Push-enabled applications, and restoring your iPhone as new are three escalating steps you can try to fix your battery problems<\/a>.<\/p>\n

Let us know how they work for you.<\/p>\n
