I have an HTC HD2. The main problem in my phone is that it loses its battery life very quickly. For most of the times I have to keep it for charging so as to get it going. I would like to know from the people whether applications and programs in my phone could be responsible for sucking battery life of my phone. If yes then, can I turn off my HTC HD2 application? Is it possible to turn off HTC HD2 applications in order to save some battery life? How can I do it? Please advice. Thanks.
