Battery Manager is an android app that displays your current battery level, allowing you configure your phone's settings based on its power level. I believe most of you hope that your phone can run as long as possible, but some programs, especially some pretty big battery-killers will greatly consume your power. Why do your power be drained so badly while you do not use your phone so often? Because some settings are on even when you are not using them, while some of them are unseen and unknown power-killers. So you need a power-controller to easily and quickly toggle the main power-consumers, like Wi-Fi, Bluetooth, Wireless and GPS, etc. Battery Manager is such kind of tool.
It shows the current condition of your battery, including level, statue, health, voltage, technology and temperature, enabling you to significantly improve the battery life of your android device. It gives you a quick access to 4 main services: Wi-Fi, Bluetooth, Wireless and GPS. There are respectably four buttons that can toggle the 4 services on and off. Once one service is turned on, the related button turns green. So you can turn those services on and off based on your needs without having to configure them in settings. Not all these four services are needed to turn on all the time. For example, you do not need GPS unless you are tracking location. You only need to activate Bluetooth when you are sending or receiving data. When battery level is lower than 5%, Wi-Fi and Bluetooth will be auto-turned off to extend the life of your battery.
The developer gives you four modes to choose, namely, power-saving mode, standard mode, low brightness mode and browse mode. These fours modes will auto-switch based on different situations. For example, browse model keeps the backlight turning on, specifically designed for reading. Plus, you even can customize a mode that suitable for you if these four modes do not meet your needs.
You need Battery Manager to manage your services, so that you can enjoy your android phone through the day without worrying the power-off.
