    Battery Life of iPhone 4S Draining Too Fast? Try Calibrating the Battery
    [​IMG]

    Some users are indicating the iPhone 4S battery isn’t lasting as long as expected, this comes alongside separate reports of iOS 5 battery life draining quicker than usual. While some of the 4S battery life complaints could be attributed to the aforementioned iOS 5 issues (most of which are easy to fix by adjusting settings), there could be an even simpler explanation, the battery needs to be calibrated.

    In a post comparing the iPhone 4S and iPhone 4 battery life, MacRumors reports that calibrating the battery can make a substantial difference in battery life, as “some [iPhone 4S users] have found their battery gauge to be inaccurate until this is performed.”

    That recommendation is in line with Apple’s official battery life tips, and they specifically suggest charging the battery to 100% and then completely running it down at least once a month:

    For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

    Apple also recommends turning off features within iOS that you don’t use, which we can confirm makes a substantial difference for all iOS devices, not just the 4S.

    Of course there could also be some technical reasons that the 4S battery may not last quite as long. The iPhone 4S tech specs show a significantly faster processor and GPU unit, in addition to an improved battery. The added power of the CPU could be impacting battery life, but in real world tests performed by iLounge, the difference is not particularly significant. Specifically, they measured the iPhone 4 and 4S, and found that in many cases the iPhone 4 has slightly better battery life, although they caution that ultimately how long your battery lasts largely depends on how you use it.

    iOS 5.0.1 Beta Resolves Battery Life Issues for iPhone 4S & iOS 5,Public Release soon
    [​IMG]

    Apple has acknowledged battery draining issues with iOS 5 and has since released a beta version of iOS 5.0.1 to developers, indicating a public release is due soon. The update aims to fix iOS 5 battery problems without modifications of settings, bring multitasking gestures to iPad 1 without the third party tweak, and resolve several other bugs and issues that shipped with iOS 5.

    Currently iPhone 4S can disable Location Services like Reminders and Time Zone to improve their battery life, but the official fix from Apple will appear soon and should allow 4S users to re-enable such features.

    Some battery life issues with the iPhone 4S and iOS 5 were confirmed directly by Apple in a short statement to The Loop, saying:

    "A small number of customers have reported lower than expected battery life on iOS 5 devices. We have found a few bugs that are affecting battery life and we will release a software update to address those in a few weeks."

    This was quickly confirmed by developers indirectly, with the release of the iOS 5.0.1 beta update. The primary fixes in the developer build 9A402 are:

    - Fixes bugs affecting battery life
    - Adds Multitasking Gestures for original iPad
    - Resolves bugs with Documents in the Cloud
    - Improves voice recognition for Australian users using dictation
    - Contains security improvements

    The beta release is available for all models of iPad and iPad 2, iPhone 4 CDMA & GSM, iPhone 4S, iPhone 3GS, and iPod touch 3rd and 4th generations.

    If you are not a developer, try some of these tips to regain battery life until the 5.0.1 update becomes publicly available.
