I’ve not read the actual legislation, but it sounds like you could be compliant with these rules as long as it’s theoretically possible to replace the battery with a screwdriver - manufacturers wouldn’t have to go as far as old-style swappable batteries that you just pull out and plug a new one in.

Same here. Fairphone 3 from first shipment, second battery, and I keep the old one around as a replacement on hikes. Way better then a power bank.

I also dunked my phone more than once in wash water and bathtubs (small children) and never had to do more than pull out the battery and spread the parts to dry for a day.

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.
