Nothing is more important to a mobile device than battery life. Obviously, without electricity the iPhone is nothing but a brick. There are many battery saving tips that can help, but none of these is a comprehensive solution. BattSaver for iOS 7 provides highly customizable, one-stop radio management tools to extend battery power.
Users can toggle any number of specific options to control when and where radio components are turned on or deactivated to save juice. While the number of toggles can be overwhelming, there are battery saving Strategy presets such as iMessage friendly, Normal, Aggressive, and Ultimate. Each level will take more aggressive steps to disable cellular and Wi-Fi radios depending on circumstances.
Besides options which can activate or deactivate radios when specific apps are running, faster cellular data speeds can be turned off to save power. Data can even be switched off automatically when connected to a Wi-Fi network. Car mode makes it easy to automatically switch Bluetooth on while charging, and even locking the device can be configured to silence the radios.In addition to radio management, comprehensive battery specifications and usage data can be accessed. There’s even a graphing function to measure how much power consumption has occurred over time.
