How to Improve Battery Life of an Android Device

Buying an Android phone has become so common now as the Android OS has made itself the most powerful platform all over the world. It has got millions of free and entertaining apps, games and tons of breath taking features in it. The task management and multitasking features in it keeps on getting smarter and smarter day by day. But it is always said that every good thing has its some or the less drawbacks. Android too have them. The most common drawback in Android observed is its fast draining Battery power. You can check the battery status of your phone by following the path:
Settings-> About Phone -> Battery use

Many of the new expensive flagship devices show a long lasting battery life, but not everyone is capable of buying them. In the early days, task killers and app managers helped a lot clearing some memory thus prolonging the life of your Android’s battery. But over time, Android has become more efficient in its processes and just by clearing memory will no longer help to save battery life. Thankfully, there are many Android developers who are working and looking for ways to improve the life of a Smartphone’s battery.In this article we have tried to highlight some main basic points which can help your device to extend its battery life by a good chunk.

• Reduce the brightness of your device

The brightness of your device consumes a lot of battery life at a devastating pace as compared to any other component. Although you must be loving the brighter, colorful and large display of your device, but remember that this is the only point that your device battery life drains quickly. You can adjust the brightness by following the path
Settings-> Display->Brightness

Scroll the slider all the way to the left (as far as necessary to view the display comfortably) for reducing the brightness. Many of the new flagship devices have an Auto-brightness feature included which helps to automatically adjust the Screen’s brightness and lengthens your battery dramatically.

• Use only 2G networks

If you do not want to access to networks like 3G or 4G network, or in case you don’t have any access to high speed data network, then you must tick the option of using only 2G network in the settings. It can be done by following the path Settings-> Wireless and networks->mobile networks->Use only 2G networks. This can help to save certain amount of battery. You can still have access to EDGE network data and Wi-Fi if needed.

• Set shortest length of screen timeout

With these settings, your device screen will be automatically turned off after a certain interval of in-activity. The shorter the interval, the less power will be used by your device. It can be done by following the path Settings->Display->Screen timeout.

Each and every second counts here, so set the screen timeout to the shortest available time. Android has the minimum of 15 seconds and maximum of 30 minutes timeout. Set that figure to 30 sec or less for better results.

• Turn off Bluetooth and Wi-Fi when not needed

When the Bluetooth is turned on, it searches for devices having Bluetooth thus consumes much of battery and is the major battery drain culprit. Same like Bluetooth, Wi-Fi also drains more amount of battery.  When turns on, the wireless networking transmitter uses quite a bit of power. Even when it is kept on, it automatically starts searching for open network. Hence it strongly recommended to turn off your Bluetooth and Wi-Fi when not in use. It can be done by following the path Settings->Wireless and networks.

• Turn off GPS when not needed

When the GPS is turned on, it automatically looks for satellites and prepares information that needs to be send to any app, without knowing whether an app that uses GPS is running or not. In case if you are not navigating you must definitely turn the GPS off, so that your device can use any other location services that your network provider offers. For turning if off, use the path Settings->Location and Security->Use GPS satellites.

• Turn Off the Vibration mode

Most of the peoples prefer to use Vibration mode instead of playing a ringtone. But unfortunately this causes the battery to drain quickly. As in Vibration mode, the vibration motor present in your device rotates a small weight that makes your device shake. In contrast to that, a ringtone doesn’t consume much power. If you don’t want to be disturbed audibly, then turn off all the modes and keep the device in your view. For turning it off, use the path Settings->Sound.

• Close the Apps running in the background

Android shows the best multitasking feature that has the ability to run more than one app at a time. But this can drain much of your battery as each app burns a lot of energy by using some of your phones processor share. Thus you must kill the apps that you don’t need which in turn will help to reduce some load from your CPU and also the power consumption. The apps can be killed by long pressing on the screen which will show you all the running application. From them you can select those to be killed. In Android, there is an app called Advanced task killer, free and easily available on Google Play Store for killing the running applications. Background Apps can also be killed by following the path Settings->Applications->Running Applications and Stop those not needed.

 All the above points may not have much impact on your battery power, but altogether can definitely minimize some battery draining problems.
