Samsung got some flak from consumers for reducing battery capacity in last year's S6. It seems they took the hint and made up for it by including this 3000 mAh battery in the S7.

Although the battery upgrade means more time to binge on apps and games, the battery itself is well wedged and adhered in place, making extraction a little tough.

If it wasn't designed to be readily removed, then it wasn't intended to be repaired or replaced. Boo.
