Just a quickie to say that since I received my HTC Desire HD last week, and after reading through the many tips on this excellent forum, I have just managed to last 34 hours on one charge!! Sounds sad I know, but when I received the phone and left things pretty much as they were, it only lasted about 6 hours! So by doing the following I have done myself a huge favour without stopping me using it the way I want. 1. Using a Static Wallpaper. (My own Union Jack pic) 2. Turned off Sync on all Apps. (Manually done now when needed) 3. Enable USB Debugging mode. 4. Installed Juice Defender. 5. Turned down the Brightness setting to about 1/4 of the way across. (was at 100% when I received the phone. Way too bright!) 6. Bluetooth and GPS are disabled. (When I need to use either, I toggle them on/off using a Widget on one of my screens. Wifi is always on.) Quite happy now. I have also ordered a 1800 battery from ObiStore as a few people say they are worth it. We shall see! By the way. I tried to put a pic of my screen on here, (via Imageshack) but I can't seem to do it?
