BatteryFu is an Android application I wrote to save battery life (and data) on my HTC Dream (G1). After trying JuiceDefender from the market, I was quite disappointed at how bloated it was and how it actually ended up using memory and battery on my device which went against what it’s supposed to accomplish.
So I wrote BatteryFu as a proof-of-concept to see if a lean and mean battery saver would work. And boy, does it work! I can get almost 4 days of battery life under normal usage (using conservative settings).
