How to overcome battery bug issues in iPhone 4S

It’s hardly a month ago when Apple introduced the new model iPhone 4S and users have already flooded the web with complaints about its rapidly draining battery and overheating issues.

A thread on this battery bug issues on Apple’s own forums has had almost 2200 replies and more than 140,000 views.

The major suspect of being the cause of rapid battery drain in Apple’s new iOS 5 was found in its location services system and in the Calendar sync. The Notification Centre is also suspected the culprit behind battery running out. Calendar items kept jumping and refreshing while Google Calendar doesn’t seem to bother user as well as the battery.

However, some tweaks and settings can overcome to these issues and make your iPhone back to the track.

Stop the location service. Go to Settings > Location Services > System Services > turn off “Setting Time Zone”. Leave the rest of the location settings as it is. Doing this would significantly improve battery performance.

As you can see in this post from iDownload there is significant improvement.

below is the picture taken before that little adjustment.

And that picture is after disabling ‘Setting Time Zone’.

Secondly, it appears that Notification Center has an endless loop in collecting the calendar events from Exchange and this is causing draining 4S batteries. Once you disable Notification Center, your iPhone 4S will perform well as before. So go to Settings > Notifications > Calendar > disable Notification Center. You can still have the alert style set to Banners, or Alerts and you will still receive notices about your events, obviously it will not build a summary in the Notification Center window.

If the problem still persists, you can have the ultimate and effective option to restore your 4S as a “New Device” (Not from a Backup). Be sure you have backed up the appropriate directory or backup files before choosing to set up as new.

Connect your iPhone to your PC and click “Restore”. Make sure you set it up as a new device. Restoring device creates another backup, you have to be sure to choose the right backup file from the list (the one before factory restore), it will prompt telling you there is a newer restore point. Ignore and click USE OLDER RESTORE POINT. (Note: This procedure may cause loss of data so just be careful).

The step by step guide for backup and restore to new device is here.

These methods worth a try before Apple finally make a stable solution. Lets fingered crossed.
