Hi, I have been trying to extend the battery for my HTC Inspire 4G by following the tips on this forum. But I don't know what to do about the display (4.3" LCD screen), other than decreasing the brightness (set at 10%). The battery usually dies in 5-6 hours of moderate usage and every time the culprit is Display (consumes 80-90 % of the battery). Any thoughts / advise on this issue? Are there any battery-friendly wallpapers or themes I can use ? Will rooting the phone make a huge difference?
