Own Galaxy S2 which I love and a Nexus 7 which I also like a lot.
In last couple of months same telco has pushed out FOTA updates on both which have completely ruined the battery performance on both devices.
I've tried pretty much every fix I can find including full restore from scratch on more than one occasion but no good. Battery on both are good and this has only become a problem since upgrading to latest jellybean.
Any thoughts before I biff both in favour of an iPad mini and a 5S?
