I have had my huawei p20 pro for about 3 months and a month of it was in reperatur. The first time nothing was done on the phone only with ner app checked if everything is OK, which I can do at home myself. The second time were supposedly parts replaced. Now I bring the phone over for the third time today.
The reason is that my mobile always freezes against and crashes and mitlerweike also hot. In addition, I noticed that jenavhdem which app I had opened everything gelöscbt was (eg game data, login, etc.) I've already updated my mobile phone and completely reset, the problem continues. The store where I bought it (dicitec) I would like to give any neuea gerät because it seems "all is okay"
Weis ev someone of you what the reason is and someone has the same problem.
I had exactly the same problem, your battery is probably broken.
For me, it has also expressed by the percentage of the battery has suddenly fallen down, then the phone was simply out and in between it went back to, because it has somehow "self" charged. Very weird.
It's best to change the handyman and have the battery checked
