Does turning off touch screen save battery

If youвЂ™re busy spending the next 8 hours playing Angry Birds, there might not be a good reason to have internet access, so you can consider using Airplane Mode, which turns off both Wi-Fi and the regular wireless radio. Use Airplane Mode When You DonвЂ™t Need Internet (iPad/iPhone) This makes a big difference if you are always picking up your phone and putting it back into your pocket without turning the display off. Head into General -> Auto-Lock to set the screen lock to happen as quickly as your device will let you. Head into Settings -> Brightness & Wallpaper to adjust the default level of brightness, which you can probably keep as low as 30% most of the time.Д®ven if youвЂ™ve adjusted the screen brightness, thereвЂ™s still no substitute for having it turn off quickly when youвЂ™re not using it. If you keep the screen at maximum brightness all the time, youвЂ™re wasting a lot of battery life-and the screens these days are so bright anyway that you donвЂ™t really need to, especially at night. The same thing holds true for any really hot environment: try and store your device in a cool place. Whatever you do, donвЂ™t leave your iPhone or iPod sitting in a hot car-heat kills batteries faster than any other factor, and your device that used to keep a charge for hours will eventually barely hold a charge, and youвЂ™ll have to pay Apple to get it replaced.
