Iphone X iOS 14.0 restart the phone

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
