HTC Desire HD :: Bug Which Causes The Battery To Run Down Quickly?

Not sure if this has been mentioned on here before, there is a bug which makes the operating system power hungry all the time, it seems to cause the phone to lag if you try to run more than one thing at once, another thing you might notice is when opening the Gallery the pictures take ages to load. If you want to try changing the setting which cures all the above go to: menu, settings, applications, development then select USB Debugging. Give it a try, you can always change it back again if you're not convinced, I've found Gallery now loads almost instantly, boot up time is really quick, all screens are completely smooth when navigating around, never lags, Iplayer works much better and best of Battey life is massively better. There is another app to show how much power various parts of the phone is using, before the operating system was always around 35% for me, now its always around 2%. Just thought people might like to give it a try!
