my **** battery discharges as thanks to the **** flash 6.1.2 upgrade, the best of all was 6.0.1
I hope to resolve it as quickly as possible to the battery with updates but it cost me to buy the Nexus 4
iPhone 4S, iOS 6.1.2
I believe setting as new phone will fix the battery issue. Since you have icloud backups, i hope. 😉
