About this app

Boost mobile battery life – for every charge… with our FREE battery life extender app

Now, you can boost mobile battery life… spend less time with your Android device attached to its battery charger… and get more out of your mobile life – without constant concerns about low battery level.

Kaspersky Battery Life is the FREE battery saver tool that helps you boost mobile battery life for your Android phones and tablets. It automatically monitors every app that’s running on your devices… lets you know which apps are consuming the most energy… tells you how many minutes of battery life are left… and helps you shut down unnecessary apps.

The battery saver that puts you in control
Every app that’s running on your device is continually monitored – even apps that are running in the background. You can stop any apps that are using too much energy – while ensuring your favorite apps keep running. With Kaspersky Battery Life, you can spend more time getting on with the things you want to do… and less time worrying about low battery level.

Watches out for ‘hungry’ apps
If one of your apps suddenly starts to use more energy than it usually does, you’ll get an automatic alert – so you can decide whether to halt that app.

Gives you a more accurate prediction of battery life
Because Kaspersky Battery Life is continually monitoring each app’s energy consumption, it keeps a very close watch on your device’s battery level… to give you a more accurate prediction of how much charge is left in your device’s battery – in hours and minutes.

I got this app a few months ago, mainly because I couldn't see the battery % on the phone. Just recently, as I was learning my new phone, I realized that it had much more info than that. Just when I was getting a hang of the app, it stopping working at all. Now the app won't even open. I keep sending crash reports, and uninstalling/re-installing the app and nothing works. Sucks because it was becoming very helpful to me. Would pay for the app- not for one that won't even open. Disappointed.

Works great at shutting down apps which keep launching themselves - best I've found. Unfortunately, that's only a temporary fix since those apps pop right back into your phone's memory within sometimes just a few seconds. It does seem to extend battery life, however. I have not found anything which can stop the bloatware apps built into the OS which insist on launching themselves for no reason at all.

I've tried a lot of apps that were supposed to optimise an android tablet that were both paid and free and ended up uninstalling them either because of the ads or because they didn't work as advertised (high user ratings). This app appears to work the best for speeding up my slow (over time has slowed down considerably) and that's what I was looking for.
