As if afraid the battery might run away, Samsung really didn't hold back on the glue.

Fear not! We've seen this before, and developed a secret formula for just this sort of sticky situation.

Remember when Samsung made a waterproof smartphone with a battery that you could swap in 10 seconds with no tools?

Although smaller than the S9+, the S9's battery is no slouch, and packs 3000 mAh at 3.85 V, for 11.55 Wh.

This is exactly the same as the S8, and a little larger than competitors like the Pixel 2 (10.39 Wh) and iPhone X (10.35 Wh).
