I have a strange problem with my HTC One.
Until last night, I was getting even 2 days of battery life if my screen was off.Last night, I fully charged my phone (100 %) and then went to sleep.When I woke up my phone was at 50 %, and untl 4 pm it was almost empty so I had to charge it again.The screen was off almost all the time, because I don't really use the phone in weekends since I'm home.
I was normally loosing max. 5-10 % of the battery over the night, so why the big change to 50-55 % ? Not to mention that since my phone fully charged like 2 hours ago, I lost almost 20 % of battery life, and the screen was off all this time.
I don't remember changing any settings so I don't understand what the hell happened.Why I suddenly loose so much battery ? And yes, I rebooted the phone twice.
