Best battery saver apps for Android phones


How to tell when your phone's battery life is overDid you know that some Android apps can help extend battery life? There are several applications which will disable the Wi-Fi radio when you turn off the phone's screen, and reactivate your Wi-Fi connection as soon as you turn it on, for example. Without further ado, here are some of the best battery saving apps in Google's Play Store.


Surprisingly, Kaspersky, the popular antivirus maker, has designed a battery saver application as well. Titled Kaspersky Battery Life: Saver & Booster, the app has been downloaded by over 1,000,000 people, has a stellar rating of 4.8 and is 100% free without having any in-app purchases or other nasty surprises.


Use this app to discover the amount of energy that's being used by each app, evaluate the remaining battery life, estimate the time that's needed to charge your phone to 100% and disable power-hungry applications, while keeping your favorites active at all times, if needed.


I like this app a lot because it can alert you as soon as a particular app starts to use too much energy. Then, it gives you the option of stopping it, or allowing it to run.


DU Battery Saver Pro is another great option. It discovers the applications that run in the background, increasing CPU load, and thus battery consumption, and then gives you the option of shutting them down. If you are interested in getting an app that shows you battery temperature, voltage, charging level, and more, this piece of software may be exactly what you are looking for.


To keep things as simple as possible, DU Battery saver Pro offers several 1-click optimization options: automatic RAM cleanup, automatic screen brightness reduction, automatic Wi-Fi and Bluetooth on/off triggers, and so on. One of the app's unique features is its ability of creating a fast charging routine that's fully optimized for your phone and battery.


The usage graphs are very helpful, and the program will also offer you several smart battery optimization tips.


Greenify is another versatile app which has an impressive set of features. It allows you to create a list which includes the apps that will be forced to hibernate as soon as the screen is turned off, while keeping the ones that need to run in the background active no matter what happens. It's got a powerful app analyzer which determines which applications are run behind the scenes, detecting the ones that will drain the battery, and then giving you the option to turn them off.


Greenify can work on rooted and non-rooted phones as well; it is a lightweight app which uses very few CPU and memory resources. In fact, its makers claim that the app will make your smartphone run as fast as it did when you purchased it.


GSam Battery Monitor is the last software on this list. It's another powerful app which helps you discover those evil battery draining applications, sorts them according to CPU usage, required sensors, wake time, and more. If you like widgets, GSam allows you to display the battery status and the remaining time on your home screen. And if you want to create alarms that will be triggered when charging levels reach certain percentages or the temperature of your battery exceeds a set value, GSam has got you covered as well.


My recommendation is to test all these apps, and then keep the one that works best for you.
