Maximum Capacity 88% for over a year... does Maximum Capacity get stuck? (alien.top)

I don't believe it to be accurate. Months ago, I turned off Optimized Battery Charging to see if I could "use it up" at all, nope.

Here's someone else in a similar situation, trying to get their battery health below 79%.

https://www.reddit.com/r/iphone/comments/zkhggx/trying_to_get_battery_health_to_79_percent/

Does anyone know if there's a reset on Battery Health, so however the Battery Health is calculated, it re-calculates from scratch?

This is the best info I've found so far...

https://www.reddit.com/r/ios/comments/a6ter0/reset_battery_health/

I had 84% of maximum capacity and I did a calibration of the battery (Charged to 100% --> draining all battery --> waiting 8 hours --> charged again to 100% waiting another 8 hours --> and a forced restart) and after the calibration the maximum capacity shows me 78%.

Not looking forward to that, but is what I'll be doing that unless someone knows of a software/ui means of achieving the same?

(I've been holding on to AppleCare+ for a full extra year until the battery drained to 79%, so I could then get the battery replaced. At this rate, I wish I'd let AppleCare+ expire. I'd assumed I could use-up 8% in a year, but it literally hasn't dropped a single percentage. I think it is stuck, and as soon as I let AppleCare+ expire, it is going to plummet.)

Mine was stuck at 81% for two years. After the iOS 17 update it immediately dropped to 78%

Mine stayed at 100% for over a year and has lost about 2% a month since then, it's currently at 88% so I'm hoping it stays there for a while.

My X dropped at a fairly fast-ish rate, but stayed at 80% for like a solid 2 years. I finally went in to the Apple Store last November and said that and said, ‘I want a replacement, it’s at 80%, but I want it anyway,’ and they let me do it. YMMV, but for my (new replaced) X, I physically couldn’t drop it below 80%.

You could of just paid for the extra battery and stopped apple care and you would of saved money lol

there’s no way it’s an accurate metric - my XR was showing 82% 1 year ago and would only stay on for 2 hours. All while the apple rep is making me sign waivers that my battery is in an acceptable state and i’m going against their advice to switch it out.
