This may be somewhat obvious advice but it makes a huge difference. If your iPhone says the battery is degraded (under 80% battery health) then take it to a repair center and replace the battery. Even if your phone says it’s at “Peak Performance” despite the battery health.
For context, my iPhone 13 mini (purchased at launch in 2021) was at 74% battery health and the battery menu said it was degraded and to seek service despite also saying “Peak Performance Capability”. I could tell because my phone would become hotter than the surface of the sun if I used it for more than 10 minutes. It would also become so slow if trying to use the internet as it struggled to load all the JavaScript and ads and such when loading websites.
I decided to get the battery replaced at the Apple Store (and they decided to replace the screen as well for no additional charge) for a total of $89 before tax. It runs like it is brand new and I could totally see me getting another 3 years out of it.
If anyone is considering buying a new device or just repairing their existing device, I can’t recommend replacing the battery enough. It really made an impact in my experience
lol my son is acting like this is the worse thing that ever happened to him. (It might, he’s lived a pretty privileged life)
