The display is the worst part of the phone, in terms of efficiency as a web server. There's no need at all for a display; visitors and developers alike connect to web servers from a remote machine. The display hardware and graphics processor on the SOC consume a significant amount of power.


Would the effect of the display hardware on battery life not be mitigated by simply keeping the display turned off?

Not sure how much that would help the power draw of the graphics processor, but it would remain idle at the very least.


Yes, the idea was to keep the display off. I didn’t think about the graphics card.


Just gate the clocks.


Unless you also want to use it as a phone.
