Iphone x battery degrading anormally

[gabrielbogatu]

Hello! I have a problem with my phone. Why my battery degraded from 88 to 85 in just 11days? I don`t understand..

Because that's how batteries work, they degrade. How quickly depends on a ton of variables and everyone's are different. I'd say if you're going to keep the phone, a battery replacement is in your future
