I have this problem with my iPhone X where throughout the day, even at say 53% battery left, it randomly switches itself off. I wouldn’t mind so much if I could just switch it back on but the issue is that I can’t switch it back on by it’s own power, it has to be plugged into a power source, whether it be a PC or by a plug socket. Any ideas what might be causing this issue? I had thought of possible a faulty battery connector but if I switch it off normally and then switch it on normally it’s fine. Thanks.
I would take a look at the maximum capacity in the battery health tab. Typically when it gets below 85% is when I recommend a replacement as that’s roughly when people notice battery trouble. But it could be an issue with the port as well. The iPhone X and above are picky when it comes to charging ports. If it’s not connected, functioning properly, or it was replaced with an aftermarket port, it can cause issues like this.
