Saner Hi Capacity Battery,
Verified Purchase(What is this?)
This review is from: SANER High Capacity Li-ion Battery for Samsung Galaxy S II Galaxy S2 GT-I9100, i9100, Galaxy S II 9100G, EB-F1A2GBU - 1800mAh (Electronics)
I bought this item as a spare battery for my Galaxy S2. It's staying power is marvellous. My normal phone usage and music and camera usage has more than doubled! However, the battery will not charge in the phone itself. Not sure why, whether this is a problem with the phone (though the original battery is fine) or the Battery itself.
However I also bought a multi point charger and the new battery charges fine in that and holds its charge excellently.
