How to build your next smartwatch UIs - without killing your battery.

NXP's i.MX 7ULP and Crank Storyboard UIs – a winning combination for 3D graphics processing on small battery-operated devices.

When I went looking for a forgotten smart watch charger while camping this past weekend, I cursed at the manufacturers who hadn't met my power needs. Yes, my girls were all over my watch playing with the graphics, but the fact my battery died hours before the sun went down was beyond frustrating.

For this reason, giving consumers a brilliant, touch screen experience that doesn't have a battery-sucking trade off is the goal of engineers globally.

Consider this: the present battery technology road map has a 2x capacity improvement every decade, while the power demand will probably increase at the rate of 2x every 18 months or so. This stat reinforces the need to continually innovate power solutions for small battery-operated devices. 

Our partner NXP went to work on this several years ago and appear to have solved this challenge with the launch of the i.MX 7ULP - the lowest power consuming GPU enabled microprocessor on the market. It runs a rich OS, but operates at MCU level low-power all while having both a 2D and 3D GPU on board, which means future smart devices like the smart watch I want for Christmas is going to have an incredibly long battery life, while having ALL the features and fancy 3D and 2D graphics I didn't even know were possible.
