WhatsMyCharge?

WhatsMyCharge? displays the percentage of voltage left on your device's battery.

WhatsMyCharge? tells you the percentage of voltage left on your device's battery more conveniently than many stock battery meters. WhatsMyCharge? keeps you informed regarding your battery's voltage by checking your battery every two seconds while running and only while running. Plus, unlike the more common battery draining battery monitors that run in the background all the time, WhatsMyCharge? only runs when you start it and it shuts down when you quit it.
