My 12 Pro Max has been at 82% for a few months now. I was going to stop paying AppleCare+ once I receive my 14 Pro Max and just pay the $69 out of warranty fee for a battery replacement. I have to charge my 12 Pro Max 2-3 times a day. I either listen to music or talk on the phone for 8 hours at work. I browse social media for an hour or 2 before bed. This all happens 6 days a week. The other day I’m on social media a little more than normal.
