Improve Android mobile battery life with a simple techneque
Most of these cases will be somewhat difficult for someone who is not so familiar in gadgets. What I have noticed is, main reason for the battery running out of juice is due to the mobile data connection. If we are enabling and disabling the mobile data connection whenever required, then it is going to make a lot of difference(it helped me to improve battery life by around 4-6times). Disabling mobile data does not just means disabling of background data. But nobody wants to always go to the settings menu and disable or enable mobile dat frequently.
In this case we can use some simple application which provides a widget to enable and disable the mobile data. Toggle Data Widget, Data Enabler Widget are two application which I found while searching on android market which are free.
Another option is to add the power widget to enable/disble WiFi, GPS.
