iFixit rates it “Difficult” for the Steam Deck OLED and says the time required is 2-3 hours:

This is a slight improvement from the original Deck’s estimated 2-4 hours:

It requires removing quite a few parts but the most annoying part is getting rid of the adhesive. It doesn’t have easy-to-access pull tabs or whatever.
They can certainly improve this. Either add pull tabs to the adhesive strips, or better yet use the mechanism from the iPhone 16 where you apply voltage to the adhesive to make dissolve/no longer stick. Or even better make it a screw-in battery without any glue whatsoever. Then update the routing of several cables so they aren’t in the way of removing the battery.
Include adding kernel level anti cheat to that. This should just give us an option to get a full refund.
