Battery arrived in Box with the information "Capacity: Large", on the Battery stands 4150mAh, I ordered 3000mAh and became ~2000mAh.
According to AccuBattery based on one charge from 3% to 100%, the capacity is around 1970mAh. That might change over time but there is no chance that this will go up to anything promised...
The wrapping of the Battery looks very cheap, but the Battery it self fits just fine into the phone.
In the end it is quite a disappointment getting not even more than 2000 mAh
You should buy from this reseller...
