Android phone hardware are getting more and more powerful. Now we get over 2G frequency cpu, over 400M frequency GPU. Here comes the most important, larger screen. For example, Samsung Galaxy SIII has a huge 4.8′ screen, not to mention note II’s incredible 5.5 display. However we have to charge our battery once everyday with the development of the hardware until we see some breakthrough in battery technology.
It’s more important to learn how to save battery life before we could
see any significant increase in mobile battery capacity. Here are a few
tips on saving your battery life,
1. Reduce display brightness. Turn down the brightness is up till now
the most effective way to save your battery life. If you go see your
battery usage, screen always eats the most battery, this is very true if
you have a large screen. If you reduce the display brightness by 30% or
50%, the battery life will be drastically prolonged. For instance, my
phone has a 4.7′ display, and I set the brightness from 40% to 20% and I
can use my phone for another day (from 24 hours to 48 hours or more).
2. Turn off auto sync. Auto sync is the essential feature of modern
Smartphone, and it drains your battery quickly too. If you have to sync
your phone book, or picture or anything else, do it yourself. Do not let
auto sync stays on. Besides, it helps save your data.
3. Turn off Bluetooth, WiFi and GPS until you need to use them. We
generally do not use Bluetooth or GPS, so it’s strongly recommended to
4. Turn off your cell phone during the night while you sleep. It will
reserve some battery power for you, but if you have emergency calls at
night, this might not be applicable.
5. Disable vibration, keypad sound and backlight. While some prefer
vibration and need backlight to read, but these features requires much
battery power to work, if your disable them, your battery will surely
6. Reduce the apps running in the background
(you need to root your phone to do this). Unnecessary features like
camera and mobile internet are those features will tremendously consume
your battery power. If you have a task killer installed, you will be
able to see how many apps are running in the background for no purpose.
So I would like advice you delete those unnecessary auto-start entries,
remove those unnecessary apps or system services. Always remember to
7. Use WiFi instead of 3G to access the internet. 3G consumes more
power than WiFi. So if you have access to WiFi network, just disable 3G.
8. Set your network mode correctly. If you have a 3G cell phone, you
have three options: Dual mode, UMTS and GSM (depending on the cell phone
you have), if you are using 3G or 2G, select the mode accordingly,
never select dual mode. Because every time you turn of your cell phone
or lost signal, it has to search for the network and this process
consumes battery power a lot.
