GREENIFY can be used on rooted and non-rooted devices. It will help to keep your device running smoothly with the optimum amount of battery life, by identifying apps using a high level of power consumption and placing them into hibernation when not in use. This way you’ll avoid battery drain and the annoying lag that sometimes occurs with smartphones and tablets. Usefully you can still conveniently run apps in the foreground as usual.

New features include Doze on the Go as well as Aggressive Doze, to be used with devices running Android 6.0 or later. One important thing to note with Greenify is that you should not ‘greenify’ essential apps that you rely on, for example, instant messaging or alarm clock apps.


This is an excellent Android battery saving app with a wealth of features to make use of. Like many of these types of apps, it enables users to track down the apps that are most draining on their devices, this time with an App Sucker feature.

7. BATTERY SAVER 2017 (free)

This is a relatively new app on Google Play and is already rated 4.6 stars by users. It works well, although we think the user interface could be more appealing, that’s merely a personal view, and you might think entirely differently. It will help you to get the most out of the battery life of your device with one-click optimization, and also features an app monitor with reminders about those most battery-hungry apps, and charge status in real time that estimates the remaining charge time with accuracy.

We also liked the phone cooler alert feature that reduces your phone temperature to a safe level by monitoring, managing and disabling processor-intensive apps.

A neat touch here is that it uses advanced cloud data technology for analysis in the cloud rather than using up further battery power on your smartphone. It’s an all round good app but doesn’t offer much in the way of configuration.

Our penultimate choice is the subject of over 10 million downloads, and all those users can’t be wrong. This efficient app can avoid your phone dying on you by extending the battery life with intelligent Internet connection management.

A nice touch with this app is that if you place your phone face down on a table or into a pocket, it will automatically turn off the screen. Most of the features of 2Battery are free, although in-app purchases are available for some extras. These include no ads, support for night mode and more.


This popular app will optimize the settings of your device to save battery life as well as stopping apps that are running in the background.
