This battery is certainly not just a representative of the cheaper variety, but certainly one of the better ones. After several crashes and then restart at absolutely changed display of the battery charge state and in some cases very massive "warming" in the field of my S3 battery with the come in the day original battery I have chosen, despite the compared to other providers slightly more expensive battery this. The only criterion in purchasing: compatibility, capacity and buyers reviews.
Fully compatible in shape and charge or charge level detection, very long duration (ie probably "real" 2200mAh) and finally back trouble-free functionality of my cell phone as the initial start-up time have consoled me well over the slightly higher price.
The decision for this product was definitely worth it for me.
