Google Nexus One with Red Screen Almost Doubles Battery Life

If battery life for you is important and you want to squeeze more out of your Nexus One than normally possible, check out the tests done by Jeff Sharkey.

He managed to figure out that you could power each specific colour on the OLED screen used by the Nexus One. In doing so, the battery life is preserved.

Jeff performed a number of tests on the Nexus One switching off colours and modifying the settings and managed to find out when using just the red LED’s the battery life on the Nexue One was almost doubled.

‘Filtering to show only red pixels only requires 35% of the original baseline OLED panel current, on average. Adding back the baseline current, the best case overall is about 42% of the original system current, effectively doubling the battery life. Also, showing only red pixels doubles as an awesome night vision mode, perfect for astronomy.Jeff SharkeyAndroid Software Engineer

Although it might not be the most desirable solution for a battery saving scheme, it’s still interesting to know that should a situation arise where you need extra juice for the day that you can simply switch off a couple of the colours that make up the screen.

For details of how to get your Google [GOOG] Nexus One to do this, check out Jeff’s blog.
