Hey guys, I’m having the strangest issue with my personal XS max (to the point I replaced it). Ill give you as much background as I can incase anyone has any ideas. The phones a bit beat (cracked screen and a dent or two) but gave me no issues when suddenly I woke to my phone dead. Unable to charge it or even get the dead battery logo. Trying the normal nee cable etc to no prevail (I mean every trick and cable, cleaning etc) so I stuck it on my wireless charger and watched it immediately light up, charge, and turn on. The next day the lighting port was still completely dead and confused continued to use wireless charging for another day. Suddenly after maybe 48 hours the port works flawlessly again. All that might have nothing to do with it but roughly a week or two later the phone suddenly slow and crashing. When I say slow I mean once it’s booted to open the phone app would take around 30-45 second. It also would soft reset about every 5 mins with use or without. Everything hardware wise still worked (camera etc) but the phone was unusable. It was so unstable and slow that I could airdrop a photo or backup and even trying a computer restore the phone would reset long before ever getting close. I’ve done tons of iPhone repairs and have seen a battery failure slow a phone to a crawl but this was extreme and the charging port issue 2 weeks earlier made me think a main board could be the issue. I proceeded to take the phone into a local but questionable repair shop to ask them to swap the main board into a different shell to see if it’s ok. They got back to me later that day explaining that the board worked flawless in a different shell and they suspected the charging port (which I thought strange). I ordered a new Battery that day and installed it in confidence the problem would be solved. Unfortunately no luck and I ordered a charging port assuming the repair shop might have actually know something I didn’t. I have no replaced the battery and charging port just to have the same issue. I tried systematically disconnecting hardware (with a restart) to see if something could change but there was no difference. So currently the only thing I haven’t scratched off the list is the screen being the problem or maybe the repair shop just lied and sent me on my way down a rabbit hole. I really want / need to fix this phone but I can’t afford to throw parts at it just to have a paper weight. Has anyone experienced anything like this or can give me some insight.
I know that was a lot of text, sorry
If anyone can help thank you in advance
