Hi, a month ago I changed the battery on my cell phone iPhone X.
At that time the system was running on iOS 13.7.
Everything was alright.
Then i updated the ios 14 system and the problems started.
My phone restarted twice a day.Battery dropped to 10%.
When I restarted my phone, the battery was 100% charged.
It also sometimes happened to me that the brightness of the display dropped to the bottom.
Battery condition is 100%.
I also tried to set the settings in the battery or reset the mobile phone to the factory settings
Nothing helped.
Where is the problem?
Non-original battery?
Can't the new ios work with her?
Or a bug on the motherboard?
Thank you for answer
