that's funny - because mine's been 94% for some time but in the last few weeks it's been acting way worse than it was a month ago. I'm still at 94%. Mine gets super super hot very very easily now. And when it's super hot the battery drains quick. Does yours do the same?
i haven't noticed any faster than normal battery drainage or my phone getting abnormally hot.

Don't over think it. It's been a year by now, which assuming charging once a day means ~360 cycles on a 500 cycle battery (Apple guarantees 500 cycles o 80%). So by all accounts, you are fine.
Correction here: You'd be right with 360 cycles if you would charge the phone from 0 to 100 every time. But if you're only charging 50 % every time because you had 50 % charge left when plugging in, you'll suddenly have only 180 cycles. Beware!

For batteries, the fact that you go from 50% to 100% is the same. It still reverses for good while the charge and chemical reaction to hold a charge. That said, going from 50% to 100% is worse.

No, it's not the same. A full cycle is charging 100 percent, and charging only 25 percent is 0.25 cycles.

My mini is at 91% health, it also has periods where it runs hotter than it used too.

Mine runs pretty hot from time to time too. Particularly if I'm in a place with poor reception but generally it's hotter than it used to be. I'm at 93% as of today.

If you use a lot of quick charges or wireless charge this builds up heat and makes the battery last a lot less. This is why with all my phones I use the old 5w charger because its SLOW and SAFE. I just leave my phone while I sleep and that's it.

13 mini bought in October 2021. I charge daily but rarely get below 50% at the end of the day. I use the MagSafe charger 99% of the time. I just checked and my battery health is at 100%. I’m not sure why.

Any others with launch day 13 minis that feel the battery is really on its last legs? Despite battery health showing 85% I find myself charging the mini at least once in the middle of the day. On vacations I need to charge it twice during the day.

I have a feeling that this is exactly why Apple stopped offering the mini.

13 mini bought in June 2022, I have only used wireless charging and have 94% battery health.

Optimized charging is on.

Mine is showing 89% bought in Oct 2021. I usually charge it by wire when it gets like 25%, not using optimised charging.

Mine is still showing 100% after running it exclusively between 40-80 from day one. Even though some will tell you it makes no difference, it clearly does 👍
I wish Apple would allow a hard 80% rule in iOS rather than just the “optimised” option as I’d be happy to limit myself to 80%.

Mine is launch day age thereabouts and is at 84% despite me avoiding charging it above 80% (although it does still get there occasionally).

Almost looking forward to it getting to below 80% so I can get Apple to replace it. Last time I tried to change an iPhone battery above 80% they said no - is that still the case?
