What is the game?

That’s called “being true to his character”.

The Galaxy S5 was the last of the mainline series to have a removable battery, and was thinner than the S9 which came out four years later. It also had a pretty good water resistance rating.

Any “downsides” to a replaceable battery are a myth.

Was this on a laptop? My Thinkpad running Mint slows down a lot when it’s charging, but as soon as I unplug it, it’s fine.

Oh, good.
