It works
About 17 hours "normal" use. About 4 hours "gaming". Had to manually bend the ribbon into place, but not other issues.

Perfect!
Rebuilt my sons S21 plus front to back... Installed this battery easily during rebuild.. He has had it for 2 months now and it is working great...keeps all charge and lasts... Perfect direct fit...and a good value for the money. P.s....S21 plus had original battery glued in place...its a bit of a pain to get out! 4.9 out of 5!
