So I bought mine new back when it came out and I've taken good care of it since. However, lately my phone has had the white logo screen pop up for a few seconds, then it takes me to my lock screen. Today I pulled it off the charger at 8am and I haven't touched it since. It's now 10am and I picked it up and I'm at 36% and it's super warm. I know I can take it in, but I don't have Apple Care or anything like that, so is it even worth it? Any idea on how to fix it?
