The app is offered free of charge by the developers. Some of the most useful features of this app are different profiles including power saving, power saving, and battery monitoring. The app allows you to establish and program these profiles on your own.


With the help of this application, you can check the battery level status of your phone with ease. At the same time, you can also track the specific applications as well as the functions that are draining the battery of your mobile device. Not only that, you can customize quite a few battery-draining settings like Wi-Fi, brightness, mobile device data, Bluetooth, GPS, and many more.

#2 GSam Battery Monitor

Rating 4.5 (68,262) | Installs: 1,000,000+

The next battery saver app you can consider is the GSam battery saver. However, the app is not going to do anything to save your phone's battery life on its own. Instead, what it will do is provide you with specific details about battery usage. At the same time, it will also help you identify the particular applications that drain your battery life the most. With this newly found information, you will be able to easily take preventive measures and increase the battery life of your cell phone.


Some of the useful data it shows are waking time, waking locks, CPU and sensor data, and many more. Not only that, but you can also view usage statistics, past usage, search time estimate for current battery status, and time intervals.

The app doesn't work as well on the latest versions of Android. However, to make up for it, it comes with a root companion that you can use to get more information.


  • Data to show which apps drain your cell phone battery the most
  • It gives you access to a lot of information, helping you make an informed choice

#3 Greenify

Rating 4.4 (300,115) | Installs: 10,000,000+

The next battery saver app that I am going to talk about is Greenify. The app is offered totally free by its developers. What it does is put all the apps that drain your cell phone battery into hibernation. This, in turn, does not allow them to access any bandwidth or resources. Not only that, they can't even run background processes. However, the genius of this application is that after they have hibernated, they can still use them.


Therefore, it is your choice when you want to use all the applications and when you want to put them to sleep. The most important ones like email, messenger and alarm clock, any other application that gives you essential information can keep you running as usual.


  • It doesn't need a lot of the phone's resources i.e CPU / RAM
  • You can modify the setting according to each different application
  • You don't need to give any personal information at all
  • Compatible with Android and iOS operating systems


  • Sometimes it's hard to figure out which apps need hibernation the most
  • Managing the app is a bit difficult and takes time and effort
  • In the free version, the app is not compatible with system applications
