Since the upgrade to iOS 6.1, the battery of my iPhone 4 last less as 8 hours without charging.

 

I have seen, that the 3G is less stable and that the battery discharge much quicker when there is less or no network (gsm, edge or 3g).

 

Have you such experience ? What could I do to prevent that without plane (offline) mode ?

 

Thanks.


iPhone 4, iOS 6.1
