Once upon a day, phones had replaceable batteries. I'm still holding on to my ancient phone specifically because of that.

Quite a few of the replaceable battery devices I’ve had over the years got old, and then I had to be careful to not flex them badly, or the battery would momentarily disconnect and drop the power. Or you loose the battery cover, or the little plastic tab breaks and now it’s held on with tape or a rubber band.

The phone battery is hard to replace, not impossible.

Most phones are 10 minutes to replace the battery, or 30 mins if you've never done it before.

I think that's about the right tradeoff for something that will be done once every 2 years.
