Apple

i’ve had an iphone 12 pro max for about 3 years. for the last 5ish days it’s been telling me there’s water in the charging port (there’s not) and i’ve just been overriding the notification with no problems. tonight i put it on the charger and it started charging for half a second, but when i went to go check on it 20 mins later, it hadn’t charged a bit. its not an issue with the charger. i’ve tried two of them and they both work on other devices. i’ve restarted my phone 3 times, cleaned out the charging port, etc etc. google also said a software update might work but i can’t charge it to download the update. is there anything else i can try or should i just give up and go get a new phone? the back is shattered and i have an upgrade available anyway, so that is a viable option for me.
