Indeed I easily installed the battery through a tutorial, but the battery does not charge more than the previous original. if I use the phone normally, that is to say a few calls, and SMS succession mails ... I'm in the red and forced to recharge my battery. So in my case this purchase is perfectly unnecessary damage. I turn now to another 2680 mAh. I'll see if it holds or not. case to follow. Regarding the delivery time however it is perfect as usual with amazon.
