About iPhone 4S Sim Failure & Batter Usage

There are hundreds of posts & thousands of page views about iPhone 4S Batter Life at Apple Support Forums. A few days, I’ve faced same problems a few days like I had no sim and sim failure errors, network losses and a few hours with full charge ! It seems problem is related directly with Apple but still there are solutions, at least two things worked for me;

1 – Changing SIM card with new one ( currently 64Kb micro sim ) solved network loss and sim failure errors.
2 – Turning off a few location based services;

  • Settings -> Location Services On -> Siri Off
  • Settings -> Location Services -> System Services -> Cell Network Search & Compass Calibration is On and everything else Off.

The result is surprising, my iphone batter is 70 % with 1 day standby and 1 hour usage.


You can still have 2 days standby with a few hours usage.
