This seems like a bad thing, any changes to make battery replacements significantly easier will almost certainly come at a significant cost. And in any case, it’s already really easy to replace the battery if you can get your hands on one.
My current 3 year old phone is also a dying breed where when the time comes, I can buy a genuine Moto battery for $AU16 delivered and replace it myself in under 30 seconds.
Some other phones need to be taken completely apart for a battery replacement
You need three different, weird, screwdrivers, have to keep track of many different tiny almost-identical screws (say goodbye to your motherboard if you get them mixed up), and prise off a very fragile connector.
That’s aside from the fact the battery is glued so firmly that there’s a good chance it’ll go up like a firework while trying to get it unstuck.
Possible, yes. Really easy? Hell no.
