Greetings, I have an alcatel one touch with lollipop. Yes I know this is a cheap phone. I thought I would take a chance on it as I got it at a great price. I have had no problems with it. I downloaded too many apps, and decided to do a factory reset to wipe it as I had too many meaningless photos on there also. Before the factory reset, I would charge it to 100% and get 30-36 hours of use. SINCE I did the factory reset, when I charge it to 100%, my battery monitors says I have about 17 hours of use, or about 1/ 2 of what I used to get. I am a very busy person and don't have time to spend charging this thing for 2 hours to use it for 15 hours and charge it again. I am about to toss it in the garbage. I am not a heavy user. I don't have it on all day texting and reading email and blah blah...just once every few hours I look at it. I have turned down my screen brightness, closed running apps, checked the battery usage which is normal (40% screen 60% OS) even pulled it apart to physically check the battery. All seems fine...but I have lost 17 hours of usage time! any ideas??? pls and thank you!!!
