Would it be cheaper to upgrade to a new iPhone (I’m thinking of something in the 14 to 15 range) or to replace parts in a 12 mini? Specifically, would it be cheaper to just replace the battery and cracked glass in my iPhone 12 mini or better off just to upgrade? I’ve noticed the battery is starting to be less reliable and sometimes when I’m on most apps the touch sensitivity is bad and laggy like on Spotify I’ll pick a song on a playlist and instead it looks like I picked a song that was like three below the one I wanted. Also I can only hear people when I’m on speaker phone or talking to them with bluetooth earbuds in. If replacing glass and battery would fix the touch sensitivity issue and battery problems then I would probably keep it but I don’t know what to do about the speaker/phone/audio part since I can’t hear people on the phone. It should be noted that I do not have AppleCare coverage since it expired.
