I found a bug that kills battery.

When you have calendar displaying in notification center you will notice you average %60 CPU usage regardless of what your doing. The CPU load is also above 3 which if your familiar with how load works is not a good thing.

Simply turning off calendar in notification center fixed all my problems. My phone no longer heats up in my pocket and I can last a day now.

This may not apply to non exchange calendars but it sure did for me. I also saw that the word calendar and mail would flip flop back and forth when viewing in notification center this may be related.
 
No issues with the battery life here. Leave the house at 730 am every day, make a phone call or two on the way into work, ask Siri some dumb questions, and stream music via BT to my car radio. Once in work I am really too busy to touch my phone, but do use it as an iPod for an hour or so. 430 pm rolls around, it is time to leave and I still have about 40-50% battery life remaining.

I think that is close to the same as my 32 gig ip4, it might be a little worse, but not by much.
 
Seems to be a common issue with the iP4s.

As seen in the Batterygate?? thread in this very forum, there is a huge amount of people having issues with very poor battery life. You will always get people saying how they manage to get 1 weeks usage out of theirs, but that is totally missing the point. A lot of people that simply don't use forums, are having a very bad experience at the moment because of the new updates.

It seems that Apple in trying to catch up to Android, have made the battery a very week point of the iPhone. It's good having a lot of processing power and features, but pointless if you can't really use them.

Battery used to be a strong point of Apple vs Android, that has pretty much evaporated with this release.
 
Ever since I have got my 4S, the battery life has been terrible. I have been lucky to get 2 hours of battery life a day. The only way to squeeze a few extra hours are to do all of this:

  • Disable Weather and Stock widgets in Notifications.
  • Disable Location Services for Reminders.
  • Go to Settings - Location Services - System Services and set Setting Time Zone, Location-Based iAds, Diagnostics & Usage to OFF.
  • Disable spotlight search.
  • Check your locations services settings.
  • Ping used to cause battery drains
  • Diagnostics & usage and select Don't send.
  • Use fetch rather than push for you email accounts.
  • Turn off bluetooth
  • Turning "Raise to speak" for Siri off.

After doing all the above I finally got some normal battery range. However, doing all those steps turns the phone from being a smart phone to being a dumb phone. The iPhone 4S has some serious issues and a full scale recall is the only option I can think of. It's not like the can give away free batteries...

Ever consider that your phone might be bad?

Take to an Apple store and let then test it/review your issues.
 
Lol at full scale recall. No over-dramatisation in this forum at all. I've had a 4S since day 1 and I've always easily got 1.5 days use out of it with texts/calls/Internet/games.

But you are having a problem - I better go and give mine back.
