Hey Everybody !
I have a silver HTC One 32gb which is unlocked and I am from the UK. I have to say ever since I received the Android 4.2 update (A while ago) my battery life has gone down. Before I would go to sleep with 100% and on a good night with nothing on the multi tasking bar, I would wake up to 96 - 99% sometimes still 100% but after the update it goes down to 90%. I remember before the update I could check my phone a few times before it drops just 1% and now it goes to quickly. I attributed it to me accidentally taking the "Power Saver" mode off but ever since its switched on again, the story is the still the same. I am expecting Android 4.3 update soon and 4.4 KitKat a while from now but can someone help ?!
