Falsely advertised and poorest quality
This battery says 6000mAh , new and upgraded and is literally much worse than my 6 year old 3000 man battery. 3% down every 10 minutes just sitting inactive. Ridiculous. This is the 2nd battery that I have purchased from Amazon through different sellers and is again falsely advertised. Like I warned other prospective buyers with the other seller , do not waste your time or money buying anything from this seller .

Seems like a good, solid battery.
After three weeks it's still going strong, holding a charge very well. Installation wasn't too hard, except for getting the flex cable back on the fingerprint reader ... but that's not a function of the battery, so it isn't a fault. The tools were a definite help. If you've got the patience to do the work yourself (and it isn't that hard) you'll save a lot of money over taking it to a technician.

It was easy because the old battery swelled up and took the back off all on its own, but the actual swap was done in under 10 minutes and the phone booted immediately.

The power shows 3000 mAh on the S9, brand new battery charged up after installation, not 6600 mAh as advertised. The original Samsung S9 battery was 6 years old and needed charging 3 times per day. This new 6600mAh battery still needs a minimum of 2 charges, and sometimes 3 charges per day. I was hoping for a single charge per day that the Samsung S9 battery delivered when new. The fit is fine, and they provide 2 strips of double sided tape to secure the battery in the case. Installation instructions are poor. I bought 2 batteries to replace in 2 Galaxy S9's. I tore the GPS antenna connection on one phone when opening the case. It rendered Google Maps, Waze and other apps utilizing the GPS as useless....unfortunate. We loved our S9's, but in the end decided to purchase two new Samsung S24's.
