How to Save Battery on Android Manually

Put your Android phone or tablet in a place that not blocking any telephone signals

We recommend you to not store or carry your device in place that potentially blocking the signals. For example, deep in the thick bags, closed desk drawer, inside refrigerator :D, etc. Because if you put your phone in that place, it will cause the phone is always looking for signals and that process is drain battery fast.

Adjust your phone display brightness to minimum levels

You can change display brightness by doing this: press the HOME button > press the MENU button > click Settings > click Display > drag Brightness slider to minimum level. Do not thick the “automatic brightness”

Use wallpaper, background, and themes with dark color.

This method will improve Android battery life, but it’s only work in a cellphones or tablet that uses AMOLED screens. If this method used on non AMOLED screen, there will be no difference in the battery usage.

Turn off Wi-Fi, Bluetooth and GPS when not in use

To activate or deactivate Bluetooth or Wi-Fi can be done by pressing HOME Button > press the MENU button > click Settings > select Wireless & Networks > to turn it off, clear the check mark on the Bluetooth or Wi-Fi.

To turn off GPS can be done from Settings > Location & Security > uncheck the GPS and A-GPS (assisted GPS).

Turn off Animation

Animation does look beautiful, but it use CPU that can drain battery. To save battery on Android, it’s better to turn off all animation, include the live wallpaper.

To turn off animations can be done by pressing the HOME button > press the MENU button > select Settings > select Display > Click Animation > select No Animation.

Turn off sound button and haptic feedback

When not needed, you should turn off the button sound and vibration. You can turn it off from this menu: Settings > Sound > clear the check mark from the following options:

• Audible touch tones (play tone when using dial pad)
• Audible Selection (play sound when making screen selection)
• Screen lock sounds (play sounds when locking and unlocking screen)
• Haptic Feedback (Vibrate when soft keys are pressed and on certain UI interactions)

Remove widget

To save battery life on Android, its better if you remove widget that animate and also the one that use internet connection. For example, weather widget forecast is looks cool, but if you rarely use it, it’s better if you remove it because it will drain the battery.

Set your data connection in 2G mode (GPRS / EDGE)

We suggest you to set 2G only connection whenever the signal condition in your area is not so good. For the record, if the connection is set to 2G only, the Android’s battery life will be more efficient, but the internet connection speed will be reduced. Therefore, if you want to download a large file, it’s better if the 3G connection is activated because if it still in 2G connection, the download time will be longer and it will draining battery more.

Turn off synchronization and background data

If you turn off this feature, it will greatly improve Android battery life, but of course it also has its disadvantages. For more information about this topic, you can read article: how to turn on and off synchronization and background data on Android (click here)

Completely turn of internet connection

If you done this, your android battery can last up to two times longer compared to when you always activate the data connection. If you don’t use internet or you don’t wait some urgent email, then it’s better to turn off internet while you sleeping. To do this, you can read article: “how to turn off internet connection on Android” (click here)

Remove (uninstall) rarely used applications

By removing applications that you rarely used, it will free up phone memory space that will make the system work more efficiently thus will safe battery on Android. Less application also means fewer problems. If you rarely use the application but you don’t want uninstall it because you think someday maybe you’ll need that app and you don’t want to re-download the app, then you can back up the application first.

Set the screen time out

The screen is one of the hardware that consumes battery a lot. You should set the screen time out as fast as possible and always to turn off the screen when it is not needed. Why we have to set the screen time out? Because when you carry your device on your pocket, there is a chance the power button is accidentally pressed and it will turn on the screen. Therefore, if you not set the screen time out, the screen will stays on and you not knowing it.

To set screen time out, you can do it through Settings > Display > click Screen Time Out

Log out from applications

If you not use it, you should log out from any applications that use services or background data. For example, if you use social networking apps such as Facebook occasionally and you don’t need active notification, then you should log out from your Facebook accounts. If you don’t do it, the apps will continually use internet connection on the background and it will consume the battery.

Always press the BACK button instead HOME button
If you already done using Android application, always click exit button from the app menu or always press the BACK button instead the HOME button to exit from the app. By pressing BACK button, in most case, it will completely terminate the app. But if you use the HOME button, the Android apps will run in the background and sometimes it’s still use the CPU (processor) thus drain the battery slowly.

How to prolong standby time using the best android battery saver apps

Below are some applications that I already tried that can prolong battery life.

Watchdog Task Manager

This app is actually not an Android battery saver application. However, it is really handy to monitor Android application that running in the background. The function is to notify you every time some apps use CPU excessively. When there is one of the app use CPU more than normal, you will be informed immediately through the notification panel + vibration and you will be given the option to turn off  (kill) the app, ignore it, or put it in a white list (you let the app use CPU as much as needed).

If you know which applications that are often use CPU while running in the background, you can make the decision to remove (uninstall) the app to save your Android battery or you can keep it, but at least you know that apps is the one that drain your battery.

Watchdog Task Manager

Above picture shows that the 6.7% CPU is used by applications that running in the background. To find out what apps that are using CPU, you can simply click the “CPU” tab as below picture.

Watchdog Task Manager CPU Tab

You can also directly kill Android applications when you thing not necessary. However, if the application is running in the background but it doesn’t use the CPU, then it doesn’t need to be turned off. For further information about this matter, you can read: “Don’t use automatic task killer Android” (click here). Also, we suggest you to not turn off the “system” apps and also any apps that contain word “Google”. For example, you can look at the red circled apps in the above picture.

Just for note, all the monitoring apps (just like Watchdog Task Manager) is using CPU a little bit, so if you already install this application and you don’t get notification at all for a long time, then you can uninstall this app. But, it you often installing many applications or just update it, then it’s better if you keep the Watchdog Task Manager to make sure you don’t have any bad application.

ShutUpBatterySaver

This application is quite unique and pretty helpful in saving Android battery life. It has a function to activate auto synchronization only at the specified time. For example, you can set auto sync feature active every one hour for ten minutes. This means that every hour, Android phones will synchronize with Google server (or with any applications server) and after ten minutes the auto synchronization is turned off. You are free to determine when and how long you want to active auto sync. It also has a feature to automatically turn off internet connection if the phone signal in your area is weak.

ShutUpBatterySaver

Caption:

Autosync Scheduler:

• Autosync scheduler enable: click to activate or deactivate Auto sync scheduler.
• AutoSync OFF Interval: Click to set when you want to activate auto sync. If you choose 1h, then its means autos sync will active every hour
• AutoSync ON Interval: Click to set how long the phone is allowed to do synchronization

Low Signal Control:

• Low Signal Master Switch: click to turn off and turn on this feature. This allows you to turn off the Auto Sync feature and / or internet connection if the signal is weak
• Autosync threshold: Sliding the bar to the right means more powerful signal. This means if you slide the bar full to the right, then if the signal just drop a little, it will turn off the auto sync.
• Mobile internet threshold: Slide to the right to turn off internet connection whenever the signal is bad.

The side effects of using this application is you will be late receiving notification or data from any application that requires auto sync feature. For example, if there is a new email, you will get a notification at the next synchronization schedule. But in other hand, it will improve Android battery life quite a lot.

Quick Settings

Quick Settings

This application is just a shortcut to access Android settings. To use this application, you can simply install it then put the application icon on the main screen. Each time you press the application icon, the settings will appear as shown below:

Conclusion

Actually there are still a lot off other Android battery saver application that you can try. But based on my personal experience, the best way to save battery on Android is by doing manual settings just like in the above article. Currently I only use Quick Settings and Watchdog Task Manager (because I often install many applications), I don’t use ShutUpBatterySaver because I don’t need auto sync feature that much hence I only activate internet when I needed. If I find other useful tips in this matter, I will update this page. If there is something you want to ask, feel free to fill out comments form bellow, I will respond you as soon as possible.
