I’m using the phone since one month, the phone is pretty awesome. I update it last week & I got battery problem but now after a week it’s working fine. I have done a factory reset, after M update lots of app are not working fine because they all need update also. l uninstall my all unnecessary crap like speed booster, battery doctor or other apps they only consume battery. now it’s giving me 4.5-5 hours screen on time with heavy uses, and a good 1 day backup with my daily uses. I request plz charge your phone when it goes down to 25-20% or plz plug out after 100% immediately. it keeps your battery or phone healthy. you can battery optimisation for apps it’s also save battery.
after update that was only one problem with me but it’s now gone. M update gives me lots of other feature. I noticed the camera shutter sound control is missing but when I search I got it’s a legal fact so it’s not a defect. The phone is damm impressive & smooth after update. so believe yourself & update, I guess you will face a little bit problem but after uses of few days you feels awesome. good luck. sorry for my last disfavour comment to M update. Now I’m simply loving my moto.
