22 Q Battery consumption is too fast.
* 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
A
when you want it, and thus extend the battery power use.
7) To install multiple apps at one time, you may as well reboot the system. Many widget apps
on the wallpaper may accelerate battery power consumption.
8) Battery lasts less on live screen background than on ordinary background screen.
9) When Wi-Fi is turned on, the smartphone automatically seeks any Wi-Fi routers or zones
around, which consumes the battery power. Turn on Wi-Fi only when you are in any Wi-
Fi-available zones and turn it off when it is not necessary. It would be better to cancel the
Internet phone 070, which browses Wi-Fi constantly.
10) It is advisable to turn off Bluetooth when it is not in use. Once it is turned on, it looks for
devices preparing for automatic operation, which may consume the battery power faster.
11) Power Control widget will help you manage battery power consumption effectively. You
can set or block screen brightness and block Bluetooth in the Main Setup Menu. Android
smartphones are basically fitted with the 'Power Control' widget, which guarantees
viewing at a glance and easier control over each power-consuming item based on the
status of use.
12) You can lessen the battery power consumption by setting up battery-saving display
modes with 25% of screen brightness, minimizing screen timeout and unsetting
animation and illuminance sensor.
