First charge, impeccable. The battery life even surprised me in good ... But from the second charge, over. the duration was reduced so very important and after a few days, it was no longer possible to turn on the X8. The battery was HS !!! Since I put the original battery that works better. I sent a request to return, but given destination, Germany, and I think the price of the battery, I may spend more on postage ...
