An Android Smartphone offers huge advantages over any other phone. However, it is known to have a very poor battery life. There are various ways by which the user can extend the battery life- turning off the auto sync, disabling 3G network, reducing the screen brightness etc. Reducing the brightness of the screen is the most common way used by the Android users to save the battery life. The brightness can be increased/decreased by going in settings. There is an alternative and a much easier way of reducing the screen brightness for the people running on Touchwiz, CyanogenMod and the AOKP based ROMs.
