Superb battery well worth the price
Blows the new Samsung stock battery 2600mah we bought
Out of the water
The 3050 mah gutts perfectly
And rather than the new stock battery we bought needing supposedly 4 to 5 recharge cycles to calibrate which I'm.dubious about
The 3050 man.battery provided amazing power from.day one
Or still has 70+% left after a days use
