Hello, I was looking for such an application in the market but I couldn't find one that suits my needs. Would be nice to have an application to completely drains your battery with different sensors. Here's what it should do: 1. Maximum screen brightness 2. White background for OLED screens, Black Background for (S)LCD screens 3. Turning on GPS (and constantly polling it for the current location - and why not, display it on the screen) 4. Turning on Bluetooth, and preferably scan for devices in the background 5. Turning WiFi if is not already on. If mobile internet is available, but not WiFi, constantly scan for new networks. 6. DISPLAY ADS! This could be the primary revenue source, considering that transferring data puts more strain on the battery 7. Camera LED! This should preferably be turned on/off on a cycle, as apparently it has a tendency to overheat on some phones 8. Vibration! 9. Something that generates high CPU usage! 10. Polling the lighting, proximity, magnetic field sensor(s) All of these "drainers" should be togglable. Also, the temperature sensor should be polled often to be able to monitor the temperature while discharging.
