Viber - battery killer
I came across to the G2 from a nexus 4 which had 'meh' battery life. I have had the G2 for a few weeks and the battery life is awesome, I've really been blown away. I was running my nexus alongside with viber on it just because I had'nt got round to installing it or taking my music off the nexus. Finally got round to installing viber and four days in with viber on the G2 and it is absolutely murdering the battery. I'm losing 15% overnight and that is with viber set to follow wifi rules, that is, wifi goes to sleep when switched off.
I have done nothing else to the phone, no other settings changed, no other apps added. Viber is squarely responsible for crippling the battery. I lost 30% battery today with it just sat on my desk with the occasional check of my emails.
So anyone with poor battery results, if you have viber, take it off and test it for a while.
