Battery Capacity 73% and not changing on my iPhone 11

You can't recalibrate the battery. But if your battery health is 73% it should have been replaced when it dipped to 80%. Either have the battery replaced or trade it in for a new phone if you don't want to pay to replace the battery.

Hi guys, my iPhone's battery capacity number has been stuck at 73% for over a year. I feel it is incorrect because it last noticebally shorter... The iOS is 18.1.1. Is there a way to refresh or recalibrate it? The reason for that is if it can display lower capacity, I might be able to acquire a new phone. Thanks!

The battery needs to be replaced. It should have been replaced as soon as it dropped below 80%.

Hello,

I do not know if it would be available to fix it without purchasing something. You could change the battery though https://getsupport.apple.com/repair-locations?caller=grl I am new and am not an expert.

All that you can do is charge the battery up to 100%.....or as high as it will go....a few times, which might help with the battery calibration, or change the displayed number.

I wouldn't expect anything to change, but it's at least worth a try.

Your phone needs a new battery. It should have been replaced a long time ago.
