BatteryEx is a very helpful application for monitoring your battery life, and even adding a boost to it. The application has two ways of displaying the battery level and other information. The first is by means of an icon on the homescreen of your device, in the notification area, giving you quick and easy access to your battery info. The second way of viewing the battery info is in the application title (multiple options for what you would like displayed). BatteryEx also has a built in "battery booster" which will shutdown your device's cellular radio (or WiFi) when you have no signal, essentially saving you wasted battery power. BatteryEx is available for all devices OS 4.6 and higher, and on sale for $1.99 until June 11th. There is also a free version, however you will not get the battery boost feature in this version.
