100. Checklist for battery use 1 Where few antenna bars are displayed shadow zones the phone is considered to be located far from the network To send and receive the phone s positioning information more power is needed Thus batter power is consumed faster 2 When the screen LCD Back Light is turned on battery power runs out faster For example when the electric current of the LCD Back Light is 100mA h a 1500 mA battery can last for 15 hours with the LCD being turned on The longer the screen timeout is set the faster the battery runs out So shorter duration of screen timeout is advisable 3 Even when ending an app by pressing the Home key the app keeps running in the background consuming battery power You are advised to end apps using the Clear Back key 4 Rooting leads to a Super User Authority in Android system domain which may cause data modification over the battery control domain consuming the battery power faster 5 Apps subject to regular data updates e g Dodol Phone NateOn Kakao Talk and Stock Weather Widgets may consume the battery power faster if the update cycle is short 6 On Android phones cancelling real time synchronization will save the battery power Unless you need real time mail checks or contact synchronization you are advised to undo the Auto Sync item in the Setup Menu Then you can use the synchronization only when you want it and thus extend the battery power use 7 To install multiple app
