I prefer to keep my screen set at the brightest level as it helps me see it better. Purely a preference and a choice I choose to make. However, I notice that after an 45 minutes of use, my battery will drop from 100% down to around 25% while using 3G. I do have other things running such as push for email, a weather widget, and gps. I am only set to run on 3G/cdma. The battery stats state that my screen uses >60% of the battery. Given that information, does the 75% drop sound about right? I also notice now that when I am using my phone while plugged into the wall charging....I will notice a slow decrease in the charge % as opposed to increasing battery life. I have swapped out three batteries with the same results. Any insight would be appreciated. I am aware of the many things I can do to improve battery life. I am just curious if this sounds like a separate problem. Thanks!!
