This has increased my battery life considerably (the old HTC supplied battery was beginning to swell and need charging twice a day). The battery life now is miles better than the original one was when the phone was first bought. It is thicker and chunkier but that is not a problem compared with the fact that I can now have all processes running on my phone continuously and still only have to charge once every two days.
