iPhone 4S Battery Issue

I hate it! It drained in less than 5 hrs without any significant usage! My iPhone 4 was updated with the iOS 5 but the battery life was fine. I already have very few location services ON and most of my apps are not in notification center…  So now I’ll try the following:

1. Switch off Siri.

2. Switch off Automatic time zone setting.

3. Switch off  iCloud Backup.

Let’s see if this will help.
