Hello, I had to save money for a long time to buy an expensive smartphone (HTC Sensation). In contradiction to my old phone (Nokia 3310), which had to charge only once a week, I now have to charge my HTC Sensation at least once a day. I can imagine that the battery life shortens after each charge cycle, so I'm looking to find ways to enlarge my battery life. I can attach my phone about 10hrs a day USB connected to my PC, but I don't know if this helps to enlarge my battery life? Some even say it's bad for my battery, so I don't know anymore if it helps or not, and/or if it's good or bad? Any batterylife-experts over here to help me out? I can't afford to buy a new battery within the next few years. Thanks!
