I have a iphone 6s 64GB. The iphone also is fully resetted but operate very slowly (like open setting or adjusting the volume take some time) the sim card take time to be detected and have a calling failure sometime. I think it could need a CPU reballing but what component could be'?
Also the battery drain very quickly
