The battery is just a standard replacement battery, identical to the original. It's the excellent price that makes the difference! My phone now lasts up to two days without charging. Some people say that their battery is still discharging fast. The cause is probably their apps running in the background. Turn off your WiFi and location when not using your phone and see if your battery's life increases.
I bought this because I heard it might solve my phone's problem of randomly restarting. Since I've been using this battery my phone has not restarted once and it saved me from having to buy a new phone.
