360 Battery Plus - Power Saver is a free app from 360 Mobile Security Limited that supercharges your battery – safely. If you also want to cool down your battery or keep it from weakening over time, it can handle that, too. It can even tell you, accurately, how much longer your battery will last on its current charge.

Hardware and software as one

Saving battery life isn't a simple task: your phone or tablet's battery is a chunk of lithium, a world apart from the apps you normally use. 360 Battery Plus - Power Saver bridges the gap a bit, however. 360 Battery Plus taps into the information and power-management capabilities the operating system already has, and extends their usefulness beyond what you can achieve without the app. 360 tracks power usage, and throttles down the processor in real time when there's less to do. It protects your battery, and by extension your phone or tablet itself, from overheating during intensive operations where that's a risk. It can calculate how much juice is really left, and even prepares a 24-hour graph of your power usage so you know where the problem lies. While your phone is charging, it can monitor the process and ensure that each charge lasts as long as before. Best of all, it can optimize your device's battery settings with one tap.

Set it and forget it

360 Battery Plus - Power Saver's features all work to specification. What's most important is that they do this with a minimum of fuss. Some of the things it can do require more management. For example, the "exception reminder" feature tells you when your phone is getting hotter and using more battery life and processor power than usual. Making full use of this information means you'll want to go into the app and configure a thing or two, although the app can be set to automatically optimize your battery usage even in this case. Pretty much everything the app does is automatic: once you tell it which of its features you want to use, it will do its work more-or-less silently as long as it's running. With that in mind, the app's main interface does not matter as much, but it works. It is very graphical, with battery indicators or two words of text taking up most of the screen at a time. This means that if you want as much information as possible, you'll be tapping the screen a lot – but for most users this isn't an issue.

For when you have every care in the world

There's not a lot that can be said about this app that isn't glowing praise. Your device literally lives and dies by its battery life. Whether it's a power-hungry tablet or a more efficient mobile phone you're using, both can benefit from this app's power-saving features. If you're already a setting-savvy power user, this app may not help you as much. But chances are, there's still something it can do for you. Above all else, it's free, safe and easy to try, and will *probably* increase your battery life. So give 360 Battery Plus - Power Saver a chance.
