Hello all , i have a xiaomi mi6 . I have changed the battery with a new one twice , but the mobile turns off in 1 -2 hours of very regular and not very consuming use. I mean not 1-2 hours of gaming or watching videos , but just a phone call , or messenger and stand by. It doesnt go to 0% . It turns off at about 30-40% and needs about 15 minutes to be charged to 100%. Because it is the 2nd new battery I change I feel that the battery is not calibrated with the mobile. I mean , when I see 100% , it is not 100% in the reality but less and the phone when it is showing 40% it is 0% or something like that . May you help me ? I have done many factory resets , I have eliminate all the apps that run in the background . There is nothing that runs in the background and from battery stats doesnt seem something weird. I use the facebook ? It says facebook. Whatever I use , it is corect in bat stats. Is there any way of complete format the miui and not factory reset ? Or any way to complete calibrate the battery or any other solutio you can thing of ?
