I’ve had an iPhone 12 mini since launch and the battery life has become pretty abysmal. However, I’m reluctant to replace it with a newer, bigger model. My battery health is sitting at 86%, which really doesn’t sound that bad, but I feel like the actual battery life is way worse than when I bought it. Has anyone replaced their battery around this percentage, and did it give a noticeable boost?
I replaced the battery for an iPhone 6s after 3 years (75%) and it lasted another 3 years. I took it to an Apple Store.
I also purchased a kit from ifixit and replaced the battery on my daughter’s 6s. Wasn’t too difficult, but I do wish it was easier. Her phone lasted about 5 years.
