Perfectly normal. If your iPhone 11 was 100% after a year, there was something wrong with the circuitry that measured the batteries health.


Batteries degrade over time with usage due to chemical aging, that's just how they work.

You can expect about a 1% drop per month with average use on an iPhone.

Apple recommends replacing it when it reaches 80%. To check your battery health, go to Settings > Battery > Battery Health.

Hello, I’m so sorry to hear about this. I’m experiencing the same thing. I just unboxed my 14pro max 6 days ago. And now the battery health is 99%. I’m really sad about it. Also, do you mean you don’t charge your phone to 100%? You unplug once it’s 80? Also, what other measures will you advice I take please. Should my phone always be on battery saver? I also don’t press it when I’m charging. Please help. I’ll appreciate any response
