Signal Sense в Android Market

Signal Sense (v. 0.5.1) Разработано Prosammer

There's nothing worse than forgetting to shut off your phone when you don't have signal (school, work, church), and realizing 2 or 3 hours later that your battery is almost drained! That's why we created Signal Sense. By intelligently managing how often your phone searches for signal, it automatically saves your battery.
