Jeff Sharkey has figured out how to double Nexus One’s battery life by applying OLED hack that involves putting your phone into “red” mode. Might not be pretty but could be a great way to keep using your phone when its running out of batteries at the end of the day.
Best all, this might actually work on other Android phones, I don’t see why not.
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.
