You may be excited that only one app uninstallation will do it but don’t get excited and read below.
Well, if you are normal user (no social media freak) then this trick is not for you.
And now for those who wanted really to save their battery up to 20 percent – you people have to uninstall the app “Facebook”.
Yeah, you heard right. The official Facebook app consumes huge battery as well as RAM.
The trick was first tested by Android Central writer Russell Holly, and then it was followed by several others. And all of them concluded that “uninstalling Facebook app really works”.
Luckily, Facebook’s messenger app doesn’t consume this much of battery, so you can use it.
