Hi guys, I have a new Desire HD on orange, it is only a week or so old. I find the phone to be laggy and unresponsive a lot of the time. I installed System Task Manager Lite so I could do some monitoring. The CPU is almost always at 100% usage, even when I have just rebooted the phone (so no apps running etc). There are also an absolute crap ton of apps running in the background or whatever, stuff that came with the phone and that I will never use. If I root and remove, how much of a difference will this make? I am getting average of 7 hours to a full charge, with light to moderate use (no games etc but some GPS / navigation). This is not acceptable, it doesn't even get me through a working day. Any suggestions or ideas? Do live wallpapers make much of a difference as I am using Thunderstorm.
