Since my original battery of HTC at just under 3 days by holding even though I seldom Make calls, and only now and then ship a message, I ordered a nine in the hope that this somewhat longer stops than the originals. Unfortunately, I was wrong. The Ersatzkakku keeps just as long or as short as my original battery. So I decided this again to send back because I saw no reason to keep this if my HTC hold out no longer as with the original battery. The shipment by the seller was very fast and the Retoureabwicklung so far without problems. Let me just be surprised how long the refund ... In my opinion, the purchase is not worthwhile.
