GTA02 Battery Capacity (Was: Re: More about the GTA02)

[Bradley Hook]

How much juice does the display eat up when it's active? I assume it's a 
considerable amount. Could we have the ability to drop the phone into a 
minimalist mode, where all the "fluff" is disabled but bare-basic 
features continue to work?
For example, kill the wifi, GPS, bluetooth, and even the display. If you 
are in a crunch and want to extend your phone's call-time capacity, you 
could probably deal with approximating a 3 col, 5 row standard phone 
keypad on the touch-screen WITHOUT the screen displaying anything.
Maybe it's a silly idea, but I know I find myself stuck all the time in 
a situation where I wont be able to get my phone back on a charger like 
I had planned to. When it comes down to it, the Neo is a phone first, 
and I'd rather have it act as such when I'm in a bind.
