my HTC One is a battery drinker.
I mount Viper ROM + ElementalX Kernel.
With 2G all time, 2 hours of WiFi and all extra off (gps, bluetooth, sync, widgets ecc) if i unplug it on 8 am he will live max untill 7 pm with mid usage,
The only apps that can eat my battery are: Facebook messenger, Couple, Go Locker, Twitter and the double tap to wake function.
I have to bring it to warranty?
