Compatible with Galaxy J7 Battery, 3300mAh Replacement Battery Compatible with Galaxy J7 J727 J727A J727V J727R4 J727T J727T1

Battery came charged 45%, so turned off the phone and charged it. It only charged upto 85%, so I unplugged and replugged and it charged to 100%. Just to make sure I looked up how to reset Galaxy battery replacement and a website said to punch in code *#9900# and which gave me an option toward the bottom to "Batterystat Reset" So I did, followed by drain battery to 0%. Already it lasted over a day with 53% still remaining. But as instructed, I drained the battery to 0% then charge to 100% then Batterystat Reset again just to be sure. I'll update on how well battery works.

Fit perfectly,exactly as described

This battery works great. It made my old phone new again.

the shipping was fast it was a good not excellent buy, There is a OEM that is actually 2.00 cheaper on Amazon. Installed battery time will tell if it is going to last. All in all it is still cheaper than most places you buy a battery from. The only reason I did not give 5 stars is I have to see how it lasts, and it is not OEM.

This purchase saved my mom’s Dunasour phone so she didn’t have to buy another new phone. She is very pleased.

Never held a full charge. completely dies at 70% .

Works ok

My phone would no longer charge. I knew if I went to AT&T and they saw how old my phone is they would hard sell me to buy a new one. I DO NOT LIKE NEW phones!!! Found the battery on Amazon for a minimum cost of $12. It works just like a new phone now!!!!! Thank you Amazon!!! You saved me many hundreds of dollars and a ton of frustration!
