Nothing but problems ever since the ICS "upgrade" Now my battery seems to drain for no apparent reason fairly rapidly. I have background data turned off the only way you seem to be able to via ICS. (Into Data usage then set limit then restrict background data.), but my phone eats the battery like there is no tomorrow now & it sits on my desk all day hardly being used. No, I have not added any new apps or programs. I am doing the same things I have always done. Anyone else have this problem?
