Hows about a patch or app to save you from low-battery shutdown? My idea is: when the battery gets down to a set (or default) percentage, it goes into airplane mode- so that it at least retains enough juice to function if needed.

Maybe add a 10 second warning button w/ the option to cancel for a few more %.

Since this hunka burning computin' takes probably 2% of battery juice just to boot. And once it shuts down, it can't be restarted for a quick call or text. This way, you retain a little to do something with.

Whaddaya think?
