A Kindle 4 runs Linux and has a 750mAh battery, which when multiplied by 3.7V gives 2.8 Wh.A single AA battery has nearly 4Wh, so two of them give nearly triple the capacity of a Kindle 4. A Kindle 4 lasts for a good month under light use, by suspending the CPU whenever the user isn't actively interacting with the UI. You could certainly make a productive Linux-based PDA that ran for a long time on AAs, provided you wrote custom software. |
