Fairphone 3 user here. My main reason to choose this phone a few years ago was because the battery could easily be replaced.
Too many phones are perfectly functional but the battery is half dead. Another boon of non-glued batteries : You can carry two (or more) batteries to easily switch when the first one is KO. Meaning no need for portable charger and useless cables in your pocket. Phone at 10% ? Just change it, bam 100% in a second. Easy as that.
I'll probably not be the target of such regulations because I wouldn't choose an anti-consumer phone brand anyway, but at least it's going in the right direction.
I own an older flagship Android phone that is almost as good as anything that currently exists on the market. It even has a capacity that outperforms every single new phone I've looked at. The only issue is that now, after about 4 years, the battery only lasts me about a day. If I can replace my battery, I'll end up likely keeping this phone for another two years. It's still in perfect physical condition.
