ASDAWN Galaxy J7 Prime Battery Replacement, [3300mAh] for Samsung SM-J710, SM-J727, J7 Perx, J7 Sky Pro, J7(2017 Ver), EB-BJ710CBC EB-BJ710CBE EB-BJ710CBU EB-BJ710CBZ EB-BJ710CBK Battery

Looked and worked great in my Cellphone.

do the initial charge properly ( do NOT charge it, just use it until its dead, then charge to 100%, and use it until it's dead, then 1 more time., do not charge until its dead and then charge it to 100%) and it's amazing, lasts 2 days with constant use.

Fit well works great

Seems like it runs down fast for a new battery.

I keep an old phone in my bathroom for streaming music, but when I was cleaning I found it was bulging. I got this replacement as a Warehouse find and it works perfectly!

Charges to 100% but battery life isn't any better than the one it replaced.

Not charge to 100%

I purchased this battery when my Samsung J7 phone original battery stopped charging. I also purchased a replacement charging cord just in case. After testing combinations of old and new parts, I found that (1) old battery was fine, (2) old cord was defective, reason charging ability deteriorated.Based on my brief use of replacement battery, I’d say unscientifically that I find no marked difference in performance between original and replacement.
