> Fix the battery issue. They really need to fix that from a hardware perspective. Also, the OS needs to be optimized to preserve battery. The burden can't be fully on hardware.

They actually have been doing this for the past few years—for instance, when you ask the OS for a timer, the timer you get will be ±10% of what you requested so that a bunch of timers can go off all at once. This way the CPU can sleep, wake up, take care of all of them, and then go back to sleep. (You can say 'no really it needs to be exactly this time', but most of the time you don't need that). Other things as well, but that's the one that's stuck in my brain.
