iPhone 15 Pro AppleCare battery replacement 80% or 79%

My battery was great too when it had that few cycles on it. Wait till it hits like 800. I promise you you’re going to be seeing dramatically lower battery life.

If you update iOS, sure. If you don’t, no.

iPhone 6s with 1400 cycles, 10 years, and health about 63%. Running iOS 10. Like-new battery life.

7-year-old iPhone Xʀ. iOS 12. Like-new battery life. I’ve never replaced a battery.

If you don't update your phone, it's just an MP3 player. No one should be getting on the internet or entering a password into anything on iOS 10 or 12. Security nightmare.

The luddite in me would like to believe you, but I have to call you out on "like-new" in both of those scenarios. There's simply no way. Unless you've just uncovered the largest scam/conspiracy by a company ever. 😉

Well, I’ve been calling iOS updates malware since the beginning. The fact that they’re required for compatibility is the problem.

In any case, Apple might need it to drop to 79% first.

But it is like-new. I’ve tested the battery and unlike practically 100% of users, I have the original battery on the original version. It’s the same battery.

OP probably runs iOS 26, which is garbage, that’s why they’re seeing reduced (battery) performance.

As battery health begins to approach 83% I won’t worry too much about replacing the battery however once the battery health reaches 81% I will replace the battery in my device. I just performed a battery swap on my 15 Pro last month because its battery health reached 81%.

I now have a 3422 mAh battery providing my device with 105% battery health. Since my battery swap I now have 26 charge cycles on it. Since I have the Apple certified tools to do this type of work I change out my own batteries when I need to.
