There is a chance, not a great chance but worth a solid shot, that Apple will replace the battery for free or the special $30 rate they offered for the class action lawsuit they covered for any iPhone still being supported. My friend had a her iPhone 11's battery replaced after 2.5 years for $30 because the Battery Health got down into the 70's.
Just because the battery health decreased by 2% in a month does not mean that the same will happen the following month. It isn’t until below 80% where a battery replacement will result in a noticeable improvement in how long the phone can last between charging sessions. First 5-6 hours of screen on time for a phone is still pretty good.

I tested this before on an older iPhone X, when I swapped the battery and charged it in a way so it doesn’t count a “cycle” and kept it at 100% health for two years. iPhone 11 battery replacement tag on flex issues. I’m using a core battery that comes with a tag on flex. Watched the video and it showed no programmer is required to reset the battery stats. Did the welding of the original bms to the new one with no issues. Attached the tag on flex, connected to the phone and plugged in the lightning cable

Apple support would consider that battery condition degraded enough to warrant replacement. Your usage and other factors would effect how significant an improvement replacing it would be, but it would be significant.

Seems a bit early for an iPhone 12 battery replacement. 86%. I’m going off of charge cycle, which is over 500 now. As long as it's over 80% it's fine. Got an 11 pro max at home with 81% and it holds up pretty good, below 80% it gets throttled so will need a replacement then. Yeah, it works fine. Iphone 11 pro battery replacement Hi everyone. Just wanted to take feedback from those who have replaced their iphone 11 pro battery. My phone is 3+ years now and the battery has gone down to 70% health. The phone is in very good condition but the battery life is quite bad with frequent temperature warning during charging.
I wrote to iFixit and they mailed me another fix kit with the replacement battery including the waterproof adhesive. It could just be that my first battery was at slightly less than 100% and the battery was good apart from that. I will update after installing the replacement. Hx_5 • 1 yr. ago.
