Battery drain after battery replacement
So, i ordered an iphone 6 battery from amazon and replaced it properly without any damage.
Everything went perfectly but after a few days the battery started draining VERY fast. It loses about 50% in an hour.
I checked the battery capacity using different tools and they all say that battery is at 100% capacity.
I even did the geekbench test to see the performance and the performance increased to the new iphone 6 level.
I'm currently running ios 11.2.6.
Tried everything from calibration to complete restore. Nothing works!
What to do?
PS: Also, I'm not able to see the battery usage statistics since replacement.
Is this a good question?
