Unable to test due to my own failure
I messed up the repair and broke the phone myself so giving a automatic 5 stars as I was unable to test the product. No fault to the product though it was my fault for sure!

Good replacement. Need to get adhesive for after installation
Works well and fits. Just wish that there was new adhesive that came with it. My phone is in a case so it's not a big deal but the backplate comes off easily now cause the adhesive isn't there anymore.

works for now will keep updated
so far so good. ill keep this review updated as time goes on. i used the screwdriver included it was magnetic enough to make reassembly much easier with those tiny screws. taking the out is the easy part. they are so tiny and short that inserting them by finger is exceptionally difficult. but the magnetic tipped drivers made it a breeze.

New battery: Sure. "Upgraded" mAh: Not so much.
Does the trick in terms of being a fresh new battery. However, I'm not at all convinced it's actually an "upgrade" saying it kicks the battery size up to 4,500 mAh. I have Accubattery Pro installed on my Samsung S21 and, ever since installing this battery, it's only reporting a max. voltage of up to 3,300 mAh. That's a shortfall of over 1,000 mAh in comparison to what's advertised... :/

Great replacement battery
Had 4 new company phones that sat in file cabinet for over a year. Samsung S21, the phones would not take a charge or power up at all. Installed these batteries and was up and running in under 30min. Saved me the cost of not having to buy 4 new phones.

Satisfactory
Good quality, everything was as described. Perefect fit and function. Samsung galaxy s21 sm-g991u My factory battery was years old and died super fast. This replacement is equivalent to a brand new factory battery. Restored normal battery life, but definitely not "upgraded" at all. These s21s just drain the battery really fast. No way around it.
