How long will my iPhone 14 battery last at 87% health?

Hi! I got my iPhone 14 in April 2023 and for many months it was 100%, now it’s 87% and I’m stressing. I use it a lot lot, games etc so no wonder it got so low. Question is: how long will it survive, when should I change the battery and if I lose any phone storage after I change the battery!

You can expect your iPhone to drop about an average of 1% battery health per month. Note that the decline is not always linear and that you can lose a few more or less percent on a monthly basis. Your iPhone is designed to retain 80% of its battery health after 2 years, under ideal conditions.


In fact, your iPhone battery is doing very well, much exceeding the manufacturers average. You have gone about 21 months with your iPhone, meaning you would be at 79% battery health. Instead you are still at 87%!


When the battery health reaches 80%, be sure to have it replaced at the Genius Bar or an Authorized Service Provider. You won’t lose any phone storage with the battery replacement as that is built into the system.
