Q
3 Battery runs out too fast.
1. As the phone is far from the network in a shadow area(few antenna markers
appear), more battery power is needed and consumed to exchange the phone's
location info.
. If the screen(LCD Back Light) is turned on, more electric currents are consumed,
and thus battery runs out faster. For example, if the LCD back light's electric
current is 100mA/h, a 1500-mA battery can keep the LCD on for 15 hours. A long
screen timecut causes battery power to run out as much as the screen is turned on
. So it is good to set a short screen timecut.
3. Even when an app running is ended and the Home Key is pressed, the app keeps
running in the background invisibly, which accelerates battery consumption. You
are advised to end apps or programs using the Clear/Back key.
4. Rooting leads to a Super User authority over Android system domain, which may
in turn changes data in the battery management domain and thus the battery runs
out fast.
A
5. Apps regularly updating data like Dodolphone, NateOn, Kakaotalk and stock/
weather widgets accelerate battery consumption if the app update cycle is short.
6. When installing multiple apps at a time, it is good to reboot the system. Battery is
also consumed fast due to many widgets installed on the wallpaper.
