iPhone OS Battery Drainage Problem Fixes Cont.

Ok as promised I will be writing about other possible solutions for the iPhone battery drainage problem and how to fix it these possible solutions the I will list below after the break are usable on both the Jailbroken iPhones as well as the official non-jailbroken iPhones.

To make things clearer these methods also apply to hacktivated iPhones that weren't fixed in my previous post about how to solve the battery drainage issue in iPhones, so if you tried my previous solution and have a hactivated iPhone and still facing the battery drainage problem you should also think about trying below solutions before giving up.

Methods in solving battery drainage issue with iOS 4.x updates:
1. Check Internet tethering. Some reports indicate that the iPhone may be persistently attempting to establish a tethering connection, thereby draining the battery. Navigate to Settings > General > Network and tap Internet Tethering, then tap “cancel” if you it is trying to connect, or turn off tethering altogether. You may need to turn Wi-Fi off then back on to stop the tethering connection attempts.


2. Bad apps to blame? Anecdotal evidence suggests that apps incompatible with iOS 4.0 or otherwise problematic under the new release can cause battery drain issues. Backup your iPhone in iTunes, then delete apps from the device in groups (you can always sync them back from iTunes later). After each group, restart your iPhone and check for the battery drain problem. Via this method, you can isolate the problematic app and remove it permanently.

Also, make sure all apps are up to date; developers have released a flurry of iOS 4.0-compatible app editions in the past few days.

3. Turn off Push. Navigate to Settings > Mail, Contacts, Calendars and tap “Fetch New Data.” Turn off Push. for this if you see an improvement in battery drainage and want to also activate the mail push if supported, you can remove all your mail accounts and add them one by one again as it might be that the mail certificate in use for the mail accounts is no longer valid or expired, also check if contacts syncing is enabled and disable it reboot your iPhone and then re-enable it as this might also help.

4. Calibrate the battery. Fully charge your iPhone, then allow it to drain until completely empty (device powers off on its own and displays a spinning progress indicator). Then recharge your phone and check for excessive battery drain.

5. Close open Safari windows. One iOS application that consumes memory and processor time (and therefore battery life) in the background is Safari. Close all unused windows in the application by pressing the page switch button in the lower right portion of the screen then clicking the X at the top left of each page. See this page for screenshots.

6. Restore, but not from a backup (use as a last resort). As is the case with some other iOS 4.0 problems, one less-than-ideal fix for the battery drain issue involves restoring the iPhone as a new device rather than from a backup. It appears that bad holdover data from iPhone backups can cause excessive battery use. Restoring as a new phone will delete contacts and other data, but may resolve this problem.

For hactivated, jailbroken iPhone users please refer to my previous post on how to transfer your push certificates using nimble before attempting this, in order not to overload push doctor (Nerv) servers as it might just take longer to get new push certificates because the demand is just too high with limited amount of certificates available.

To do so, connect your iPhone or iPod touch to your computer, click “Restore” in iTunes, then choose “setup as new phone.”
