Iphone 13 mini heating up, then stopping
I recently got a refurbished iphonie 13 mini.
For the first two days it kept having issues with wifi connection and heating up. Like it saw the wifi, but just acted as if it couldnt connect and the internet didnt work. When i tried using it, it was heating up a lot. Id say like 50 degrees cedlsius, but didnt have a way to measure it properly, im just going off the feeling of how much warmer it was compared to my body temperature.
Then overnight it stopped. Now there is no problem with connection and its not heating up. As far as i know, no updates happened and i didnt do anything else than contact the store where i bought it.
Is it possible that the problems were related to reinstalling everything and being used after a long time? Im really worried about safety especially with the heating up. It should have a brand new battery and according to my research the swapping could have damaged the wifi antenna and possibly bad installation of the battery could lead to the heating up. But why did all the issues stop after three days?
