I haven't looked at Apple's training stuff in a while but I believe below 80% is when Apple's "performance management" kicks in. Either way you can disable it in Settings under the battery options.
I appreciate this. I'll let my friend who got my old phone know. She had a
5 (!) that she was still using until she was told the
carrier would no longer support it a few months ago. Talk about getting your monies worth out of a phone.
By that point I'd probably be ready for a new phone though. My 3 year-old iPhone XR was still at about 91% when I traded it for a 13. I know how to take apart an iPhone but battery replacements are huge pain in the ass because they're held in with adhesive that snaps if you look at it funny, plus there's the issue of Apple's cloud-based calibration software.
Despite all of that, Apple phones are still child's play to fix compared to Samsung, although much of that is due to how Apple documents their repair process very well. Literally every repair type has a step-by-step guide from disassembly to post-repair testing. Granted, none of this is accessible unless you have access to their systems, but maybe they'll make it more publicly available when they roll out that self-repair stuff they've been teasing.
I haven't done anything with the hardware side of things, I've never been good with hardware, but I really do like the way Apple generally does things. There's things I don't like, but they do things that are objectively better than Android - at least Android when I last used it six-seven years ago.
Like using third party keyboards, Android/Samsung would keep using the third party keyboard when putting in a username/password in an app or web page. That's arguably a security vulnerability, because a shady keylogging keyboard can see what you're typing. Apple switches back to the Apple keyboard when it detects a password is being entered. Even if it isn't actually more secure, it feels like it is. Of course, I'm based and use a password manager, but still. It's a nice touch.
Android may have changed that, I don't know, like I said, it's been years and Mr Substitute doesn’t use third party keyboards.
I would switch to MacOS, but they don't really support games. I don't play a lot of games, but the major one I do doesn’t have Mac support. Sucks, because an alternative to Windows that isn't Linux for people who aren't just normies would be awesome. Plus the prices are too much, even for me to justify, even after buying a gaming machine.
