    My Mobile OnePlus 3T experiences freaky and horrible Battery Drain... the battery shows 31% consumption, going down from 100 to 69 just in one hour... even though I didn't use heavy apps and I activated battery save mode ..
    kindly help me to get my battery mobile fixed ...

    battery use depends on phone use, both active and background. check the battery use screens in settings.
    also, the 3T is coming up for 3 years old, depending on the number of battery charge cycles, the battery may be starting to degrade (all rechargeable batteries degrade over time).

    I've been having this issue for a long time and been doing numerous tests on my 3T. And finally I may have found a solution. I tried factory resetting the whole phone, erased EVERYTHING (make sure to backup before you do it), then tested in places where i get the most drains (eg 100 to 20 in 6 hours), and the battery drain is gone. I urge everyone to give this method a shot, although its a pain in the *** to re-setup your phone after the reset. It works for me so results may vary.

    That only fixes the idle data battery drain problem. As for screen on time, this phone is rather old now, so it is consider lucky to get even 3 hours out of it

    Mater of fact I was thinking to do factory reset and I'm afraid to lose the photos & videos .... So now I will definitely go for it after back up the data ... Thanks alot
