  • Some apps like the Battery Doctor will allow you to disable those apps (multitasking) which are running in the phones’ background and occasionally syncing the data.
  • Many times the applications perform the background tasks and that so without ever alarming the user.
  1. Checking Phones

One more way to check the health of the battery of your phone is through the ‘hidden menu’ which is built in.

  • The monitor will also tell you which functions of the app can drain most of the battery.
  1. Clean Master

Rounding out the tools of our battery health is the Clean Master.

  • This application shines in its ability and adaptability in order to provide user notifications about various aspects of the life of their phone.
  • For example, if an application is consuming too much battery life or CPU power, you will receive a notification (subtle).
  • This information will let you know when you are using an app that is consuming or reducing the life of your battery.
  • Using these types of apps can give you a fair idea of what are the things that are draining your battery, and what you exactly can do in order to fix those issues.
