We smartphone users could have experienced the following situation somehow.

Theoretically, only in standby mode can an Android phone battery run for three days or even less. But frequent usage always places the battery in danger. Sometimes we even find the power to be low just a few hours after charging. However, phone calls and messages keep coming one by one, looking so important, and forcing us to get it done.

But what if there is no charger or socket around? It’s not always a charge box offered when you’re walking. To make things worse, the battery capacity seems to decline time after time. In this case, we do need to be aware of the importance of battery saving.

I once followed some tricks concerning battery saving. These tricks, not requiring us to install any related software (for many would dislike complicated software usage), can be said as good using habits including not to place your smartphone beyond certain temperature-range, to shut down the phone when there is no signal, and so on. Anyway, the effect is limited as many battery-killing behaviors are unavoidable.

Sometime ago I turned to an easy-to-use Android application called Battery Booster. Both the plain interface and simple operating made a good impression.

We know that battery capacity is based on system specifications. This application provides accurate information on my battery charge. Entering the operating interface, I’ve got a list showing the real-time capacity, temperature, voltage, etc, which advices me to make decisions on settings, boosting my battery.

Then all I need is just to check or uncheck the options fit for specified situations. I convert to the “Battery Tweak” interface, where I have several choices. With these optional settings, I can turn off WiFi/Bluetooth when device is locked or the battery is low. Also, settings to enable beep and select beep for warning a low battery level is adoptable.

Of course that is not enough. The originality of Battery Booster lies in two special techniques added. One is Homescreen Widget Support and the other a Smart Task Manager. The former leads me to quick operating with shortcuts to settings cutely shown on homescreen, as the latter saves more battery by killing idle process running in the background, both in order to make the application more convenient and effective when compared with others of this kind.

I recently found a new version released online, added with several features such as to show battery level on Notification Bar, different security levels support, Smart Battery Saver function optimized and other minor improvements.

I quite like this tiny widget, delicate and useful. When something does help perfect our Android OS without even a single cent, why shouldn’t we give a pleasant try?
