Good afternoon mates.
When I upgraded my iPhone 6s Plus to iOS 11.2 it seemed that the battery and keyboard were already working well at last (updated by OTA). Now after a few days with this version, I see that everything goes back to practically the same as before, the keyboard with some improvement but the annoying lags follow and the battery also falls faster than the account.
The question is, do you think that with a clean restoration and from scratch (without backup) these problems will be solved?
Thanks in advance and greetings!
