Battery life is probably the biggest annoyance that most Android users experience every day. There a hundreds of applications available on Google Play that promise to optimize system performance and extend battery life of your Android phone or tablet. Alas, there is no ultimate solution to this complex issue. We have spent a lot of time testing numerous battery-saving apps and may I say that most of them are useless at best. Today we present you our list of nine Android applications that can really prolong your smartphone’s battery life.


The following applications are covered in this roundup:

  1. Auto Pilot Mode
  2. BetterBatteryStats
  3. Deep Sleep Battery Saver
  4. Gravity Screen
  5. Greenify
  6. Intelli3G
  7. LeanData
  8. OnePowerGuard Pro
  9. Wireless Manager

Auto Pilot Mode

  • Application: Auto Pilot Mode
  • Developer: ProjectZed
  • Reviewed version: 7.3
  • Price: Free!

Auto Pilot Mode is a lightweight and free utility that automatically enables airplane mode for a specified amount of time if cellular signal drops below a certain threshold. This common sense trick saves a lot of battery life by preventing phone from repeatedly searching for signal. You can define for how long airplane should be turned on and whether airplane mode should affect WiFi and Bluetooth connection. Auto Pilot Mode can be automatically started when the phone boots on and the service will be paused if you are receiving or initiating phone call, thus preventing call drop.

Auto Pilot Mode supports Android versions 2.3.3 and up. The app supports Android versions 2.3.3 – 4.1 without root requirements. Android 4.2 and above require root access, since it is not possible to toggle Airplane mode without root access on Android 4.2+.

  • Application: BetterBatteryStats
  • Developer: Sven Knispel
  • Reviewed version:
  • Price: $2.76 / Free!

BetterBatteryStats is an application that will help you analyze the behavior of your Android device and identify programs causing the phone to drain battery. Once you have installed it, just let it run in background and collect data on battery usage. The app is using standard Android’s “batteryinfo” service to retrieve data and won’t consume any additional battery power to gather stats. After a day or two of typical device usage BetterBatteryStats will give you plenty of battery history data including kernel wakelocks, partial wakelocks, CPU states, network and process stats.

BetterBatteryStats is available for $2.76 on Google Play, but you also can download it for free from the project’s thread on XDA Developers.

Deep Sleep Battery Saver

Deep Sleep Battery Saver will help prevent battery from draining by putting your device into power-saving “deepsleep mode”. During deep sleep WiFi and 3G connections are turned off, and background apps, such as Facebook or Google Service are stopped. The app will then wake your phone at specified time intervals to check for new mail and notifications.

The application comes with five pre-defined profiles: Gentle, Balance, Strong, Aggressive, Slumberer. For example, when using Gentle profile your device will go deepsleep for 30 minutes and then will wake for one minute to grab new messages. And if your switch to Slumberer profile, the app will keep your phone in deep sleep all the time while the screen is off.

The Pro version ($2.59) of the app allows you to set up your own custom profiles and customize more parameters. There are options to disable Bluetooth and GPS connectivity or even put your phone into Airplane mode while sleeping. Deep sleep duration can vary between 5 minutes and 4 hours. And you can also set up different sleep schedule for weekdays and weekends.

Gravity Screen

  • Application: Gravity Screen
  • Developer: Plexnor
  • Reviewed version: 1.81.0
  • Price: $1.97 / Free

It’s no secret that display is the most power-consuming part of any smartphone. With Gravity Screen you can automatically turn the screen on when you grab your device, and then turn the screen off, when you place the phone back into your pocket or put it on a table.

The application uses gravity sensor to monitor the orientation of the device. When your phone is pointing downward by its top, below a certain angle, it’s likely to be out of use. In this situation the proximity sensor is activated to determine if it is covered. If so, the screen turns off because probably you placed the phone into your pocket or onto a table.

With Pro version ($1.97) you can set Table sensor options more precisely. There is also an Exclude App list, which pauses Gravity Screen if certain apps are running.

  • Application: Greenify
  • Developer: Oasis Feng
  • Reviewed version: 2.2
  • Price: Free! / $2.99 (Donation)

Greenify is a handy utility that hibernates selected apps and prevents them from running in the background and thereby saving battery life. Hibernated apps remain accessible, they are allowed to run in the foreground when explicitly called upon and you can share data with them as if they were running.

The only thing you have to do to set up Greenify is to select the applications you want to hibernate. Then, if you’re using rooted device, Greenify will automatically hibernate background apps for you. On non-rooted phones it isn’t possible to auto-hibernate apps and you have to do it manually using ‘Hibernate Now’ shortcut on your home screen.

Free version of Greenify is fully functional and does not include advertising. If you like the application, consider purchasing Donation version ($2.99) that includes some experimental features (note that these features require root access).

  • Application: Intelli3G
  • Developer: Voidv Apps
  • Reviewed version: 2.14
  • Price: Free!

** NOTE: Intelli3G requires rooted Android 4.1+ device with Xposed framework installed **

3G and LTE are useful when you require fast Internet connection, but they are much more power-consuming than 2G and often we simply do not need them. Intelli3G is an application that manages your Android phone’s connections and disables 3G/4G networks when you are not using them. Intelli3G will put your phone on 2G network whilst it’s in your pocket or within range of WiFi network. The program will automatically switch back to 3G connection after lighting up device’s screen.

LeanData – Automatic Connectivity Manager

  • Application: LeanData
  • Developer: TeqTic
  • Reviewed version: 1.2.2
  • Price: Free!

LeanData is a lightweight application that automatically manages your device’s battery-consuming wireless connections. The app can disable Bluetooth, WiFi, and 2G/3G/LTE data connections after a certain period of inactivity. Once you turn the screen back on (or unlock device) the app will make available all previously disabled connections. LeanData is an intelligent application and will neither turn off Bluetooth if there are connected devices, nor disable data connection when you’re listening internet radio.

OnePowerGuard Pro

** NOTE: OnePowerGuard Pro requires root access **

OnePowerGuard Pro is another application that is aimed at extending stand-by time and battery life of your device. The program optimizes system kernel and CPU usage to improve phone performance. Integrated Battery Doctor module detects power-consuming processes so you can shut down programs that cause battery drain. OnePowerGuard Pro comes with six pre-defined power-saving modes which turn on or off selected services depending on day time, usage, or other personal preferences.

Wireless Manager

  • Application: Wireless Manager
  • Developer: RYO Software
  • Reviewed version: 1.4.33
  • Price: Free!

Most people do not turn WiFi off even when they are in an area where there is no available wireless network. At this time your phone starts to continuously search for known networks and consume a lot of power. Wireless Manager is an application that allows you to set an interval between WiFi network checks thus reducing battery usage. When the app detects that you has been disconnected from a wireless network, and after waiting a certain period of time, it will turn off WiFi connectivity. A few minutes later the WiFi is reactivated, so the system can search for available networks again.
