Without being able to witness the batteries sold by others, the one I bought from M & L Mobile is simply excellent. My old HTC holds again more than two days without needing to be recharged. The full charge is as quick again, around an hour I would say. It was time that this had not happened. In fact, it had not happened either with the previous spare battery I bought from another vendor. Obviously, it is good.
Moreover, it is a battery for the HTC Desire tout court, not the Desire HD, Z or other derivative version.
