Lasts noticeably longer than two samsung factory batteries. More capacity at a lower price. Honestly, it's about the same as the stock battery.

No tight fit, now it needs a gentle push before it wedges into the compartment. Also, the pins on the bottom of the lightning connector are exposed. This battery is *, lasts for about 4 hours and dies after just scrolling facebook and instagram.

Overall a fantastic buy. The only issue i have is minor. This thing is just amazing.

It is a great charging device but not good if you drop your phone a lot like i do. Hopefully in the future battery case can be a little slimmer and lighter in weight.

I had to return this case, it has a big big flaw, wireless charging works great.
