Use your AMOLED Screen for Incoming Notifications
If you are a lucky owner of a Samsung S i9000, you’ll already know that the Android device boasts a wonderful AMOLED screen. You may also know that the screen does not consume any backlight energy when displaying a black screen….but that the capacitive lights however, do consume energy.
Now, XDA forum member madmack has put 2 and 2 together and has developed NoLED, an app that uses the AMOLED screen to notify you of any missed calls, SMS and any other notifcations by displaying a black screen with a red dot that moves around the top left corner of the screen every 3 seconds.
The location of the dot is random every time to ensure that different LEDs are used. Additionally, madmack states that red uses the least amount of energy to display and what’s more, the dev has also disabled the touch drivers when the black screen is active in order to save even more energy.
To dismiss the red dot, just tap the home key.
