Most Android users know that the factory settings on their device tend to drain the battery quickly. Some Android models have a power-saving option, but for those that don’t, you can still considerably lengthen the life of a battery charge by modifying the following settings.

1) Turn down the brightness of your display

You can save battery power by setting the brightness of your display to automatic. When the display brightness is set to automatic, your device will choose the optimum brightness depending on the conditions. Because most Android users spend a large amount of time indoors, this setting will be quite low. However, if you would like more control over how much power you save, the recommended setting for display brightness is 20 percent. To adjust the brightness of your display go to Menu > Settings > Display > Brightness.

2) Connect to Wi-Fi at home

Android devices use 2G or 3G mobile networks when on the move. If you are staying at home, however, you can save battery power by connecting your device to your home Wi-Fi. Android devices use less power when connected to a local area network. One more thing you will need to do is to change the Wi-Fi setting to stay connected in sleep mode. This is necessary to avoid being disconnected when not using the device. When the device disconnects from Wi-Fi, it will automatically reconnect to 2G or 3G, and this will drain the battery much faster. To modify this advanced Wi-Fi setting, go to Menu > Settings > Wireless and Networks > Wi-Fi >  Menu > Advanced. Here you can change the Wi-Fi sleep policy to never.

3) Adjust application synchronization settings

Many Android applications continue to work in the background when not in use. This is called background synchronization. If your synchronization settings are set to automatic, applications will continually check for fresh data, which uses a large amount of power. While you can change basic synchronization settings from the Settings menu on your device (go to Menu > Settings > Accounts and Sync ), the settings of an application offer a much higher degree of control. Applications like Twitter and Facebook allow users to set a sync interval time. For Twitter and Facebook the maximum sync interval you can set is four hours. This means that your device will load in fresh data every four hours. The minimum sync interval is 30 minutes. Facebook also enables users to set synchronization to manual. That way, you have to retrieve new posts yourself by refreshing the screen. Adjusting the synchronization settings of your most important applications will stop the battery from draining so quickly.

4) Turn off the GPS

The GPS (global positioning) function of your Android device doesn’t just require a lot of power to run, it can also prevent your phone from going into sleep mode. That is why it is a good habit to switch of the GPS function when you don’t need it. Switching it off will keep applications that are working in the background from activating the GPS. If you don’t switch off the GPS, your device will keep using battery power while it is trying to locate satellites to connect to. The GPS settings can be found under Menu > Settings > Security and Location > Enable GPS satellites.

5) Don’t use task killers

Task killers are applications from which you can stop other applications from working in the background, thus improving the performance of your Android device and saving the battery at the same time. Unfortunately, in all but a few older versions of Android these task killers are no longer effective. Android devices are designed to use mainly RAM (random access memory). Many Android users think that if their device’s RAM looks full, it will impact on performance, but that is not true. Performance is determined by the device’s CPU (central processing unit), and task killers have no effect on this. Instead the task killer is just another application using up CPU cycles and eating away at your battery life.

Tweaking the settings on your Android device can dramatically improve the life of your battery. You can use these tips separately, or together, in any combination. It is also worth it to look at each application individually to see if you can improve settings there. Of course you can always keep a portable power pack handy for emergencies, but by applying these tips you should be able to get through a full working day with your device.
