The folks over at Onyx International had quite the idea: why not take the famously battery-efficient E Ink technology and use it in a smartphone? It appears that concept is one step closer to fruition, with Onyx showing off an Android-based E Ink smartphone at IFA last month.
The phone is still very much just a prototype, but the battery-sipping E Ink technology is so efficient that the device has a whopping one week battery life (not one month, as incorrectly stated in the video below). E Ink’s efficiency stems from the fact that it doesn’t require a backlight and only uses power when something on the display is changing. As such, it’s possible that Android’s UI could get tweaked to be optimized for the display technology — obviously, it’s currently optimized for LCD screens — to minimize the amount of on-screen changes and refreshes.
Not much else is known about the E Ink smartphone, other than the fact that it’s powered by an ARM Cortex A5 processor, though the specific type is unconfirmed. Also unknown is its exact weight, but it is extremely lightweight, coming in at under 100 grams.
