Of course it can. Why do the English not have separate words for (ordinary) battery and a rechargeable battery
But as you know these rechargeable loose capacity over time.

And wouldn't it be nice if it last from getting up to bedtime

Or is there built in obsolescence

The rechargeable as such is the obsolescence.

With some smartphones it's really difficult to change the battery and you usually loose the waterproof/watertight feature (IP 67 or the like) because the housing has to be opened. Remember the times when the battery could simply be unplugged?

Yes so do I, it seems easier than getting the phone out and performing a few swiping motions or whatever is required. The pics above make it look like they make it especially difficult to do a battery replacement....can't they be recharged like the phone? Or is there built in obsolescence...which makes buying one a mugs game!

Looks good to.
