Saving the Battery Life of your Android Smartphone / Tablet / Note:

First of all you need to check in Settings > Battery about what’s eating the battery at most. You’ll probably find “Screen” at top, so we’ll begin optimizing the Display settings for your Android device.



Always use as low brightness as you can. This is highly recommended as high brightness produces more light out of your phone’s screen and stresses the battery and results in battery drain.        Screen

Solution:  To adjust the brightness on your phone, follow these steps:

    • Tap Settings.
    • In Settings tap Display.
    • In Display tab Brightness.
    • Now in Brightness > Untick -Automatic Brightness / Auto Adjust and set the lowest brightness. Auto Brightness

Screen Time-out:

Always use minimum screen time-out. Sometimes when you’re done using your Android device, the screen remains on for a duration of 30 seconds or more. You can set this time-out to the minimum available time and unstress your device’s battery.

Solution:  To adjust the Screen Time-Out goto Settings > Display > Screen Time-out > Set it to to the lowest available option.Screen Timeout

Auto-rotate Screen:

Auto-rotate uses the G-Sensor of your Android device to determine in what direction you’re holding your Android smartphone and helps you to view your screen in that direction. Use of G-Sensor is also linked with the battery life of your device, so always turn off Aut-rotate screen and turn it only when you need it.

Solution: To turn off Auto Rotate goto Settings > Display > Untick Auto Rotate.Auto Rotate


Always use a static wallpaper. That means you got to avoid Live wallpapers on your Android smartphone. Live wallpapers include screen animations, graphics are high. These animations and graphics probably use CPU and GPU of your device as well and the processing results in more battery usage.

Solution:  To set a static wallpaper, goto Setting > Display > Wallpaper > Pick a Static wallpaper and ignore Live wallpapers.Wallpaper2

Framework Animations: 

Disabling Framework Animations is another way to increase the battery life and also improve the speed of your Android device. These animations work when you open an app, switch between apps or you go back to the home page or press the home key to come back to your device’s home. These animations definitely eat battery while processing.

Solution:  To turn off these animations goto Settings > Developer Options > Scroll down to Drawing Section and turn off following three:

      • Window Animation Scale
      • Transition Animation Scale
      • Animator Duration Scale

Set all these three to “Animation Off”.

In case your device is running on Android 4.2.2 and you can’t find Developer Options in Settings then goto Settings > About Device > Tap build number for 7 times and you will get Developer Options activated in Settings. You can proceed once activated.Animations


Try to ignore the use of Widgets on your phone’s screen. Widgets keep updating em’ regularly, whether you’re using a Weather update widget, or a Social Feeds widget or any other. These widgets can use the CPU at any time and start a process on your phone that directly affects the battery life of your device.

Use light themes on LCD displays:

Always use light/brighter themes on the devices having LCD displays. This is effective when you want to keep your phone’s brightness as low as possible and you still want to keep everything visible, a brighter theme maybe a lot helpful while keeping the device’s brightness at the lowest level.


Use Dark Themes / Graphics / Effects on AMOLED & Super AMOLED Screens:

Using lighter themes on AMOLED and Super AMOLED screens consumes more power and results in more battery usage. Using dark themes / dark graphics on AMOLED or Super AMOLED powered devices will effect the battery. Basically using dark themes on these screens uses less pixels and doesn’t put much burden on the system, so keeping everything as dark as possible will be a life savior for your phone’s battery.


Optimizing the System:

Turn of Auto – Sync:

Auto-Sync consumes your smartphone’s battery to the worst extent. Basically this feature keeps on checking all your synced accounts with your cloud storage or with your gmail / email and other such services and displays / updates the missing data. Disabling Auto-Sync may save your battery a life.

Solution:  To disable Auto-Sync goto Settings > Accounts > Google > Untick All ticked Sync options.

Similarly unsync the options for other accounts that are not in use.Auto Sync

Turn of NFC & Bluetooth:

Keeping NFC and Bluetooth and other such wireless connectivity options is a lot helpful as well. NFC uses your phone’s screen and results in consuming the battery, similarly Bluetooth stresses the system as well and eats a lot of battery.

Solution:  Goto Settings > Connect & Share or Connectivity > Disable Bluetooth & NFC.

It is always wiser to enable these options only for a while when you actually need em’.NFC

Turn of Mobile Data:

Believe me or not, Mobile Data eats more battery then the WiFi. You may use Mobile data only when it’s needed otherwise it will definitely result in battery drain.

Solution:  To disable Mobile Data, goto Settings > Network Connections > Mobile Networks > Disable Mobile Data.Mobile Data

Use Airplane Mode When Possible:

Always turn on Airplane mode when it’s possible and when you don’t need your Network. Enabling Airplane mode stop the Modem / Radio of the phone from working and gives rest to your smartphone and results in more battery life.

Solution: To turn on Airplane Mode goto Settings > Airplane Mode > Check it.AirPlane

Stop Clearing Your Device’s RAM:

Sounds weird, but that’s right. Most of the Android smartphones do not know about this fact and they keep on opening the task manager on their Android device and clear it’s RAM again and again. This is basically known among the users as clearing the device’s RAM always wipes the applications running at background and leaves a positive effect on the device’s battery, while this assumption is totally wrong.

RAM (1) RAM (2)

Android device’s RAM uses the same amount of battery whether it’s full or empty, so clearing it again and again won’t help your device’s batter at all. Basically what happens is, when you close an application or clear your device’s RAM and open that application again, the app opens up from scratches, starts it’s necessary process and uses the CPU. Use of CPU = Use of Battery, so if you leave it opened and use Home Button to turn back to your phone’s home screen or come out of that application, then accessing it from recent applications will be surely helpful as it won’t load from scratch and won’t start all process once again.

Charge Your Device’s Properly:

Charge your Android device properly and carefully always. Do not wait for the battery to drain to 0%. Always plug the charger in as soon as your device falls to 50%. This will help the battery life cycles, and help the battery to remain efficient.

Always Use Correct Charger:

Always use the correct charger to charge your Android device. Do not use a charger with invalid voltages, or invalid power to charge your device. You may use a slow charger for this purpose when you’ve time, specially when you’re sleeping. Using a slow charger keeps the battery calm. While use of fast charger is only efficient when you’re in a hurry.

It is always preferred to use the Stock Charger of your Android device.

Use ART in Android 4.4:

ART stands for Android Runtime that is replacement for Dalvik Runtime in Android 4.4 KitKat. Quite similar to Dalvik, it basically helps the phone to handle apps.

Use of ART pre-compiles the apps, so that whenever you open an app you don’t disturb the CPU of your phone that much.  As mentioned, less use of CPU always results in less use of Battery.

Solution: To use ART goto Settings > Developer Options > Select Runtime > Use ART > Reboot.

Rooted Users:

If you’ve rooted your Android smartphone, the root access may be of a lot worth when it comes to saving the battery life of your device. You can undervolt and underclock your device’s CPU and make it use as less battery as possible. Following links may help you:
