PDAs, Cellphones, Wireless One of the new requirements of WM5 was that it now had to be installed in the flash ROM instead of the main RAM (on WM5 there is only "program" memory and not "data" memory shared anymore). Microsoft's Mike Calligaro blogged as to why this change can save lots of battery life.

Pocket PC using RAM

My ipaq 4155 has never lost a single thing. It has a second battery which keeps RAM charged plenty long even though I can't turn on the PDA. I use my PDA with WIFI alot and it kills the battery. I normally charge it once it shuts down on me and won't turn back on. Yes Flash would be safer but I can back up my PDA to nonvol memory (ROM) on the PDA itself without the use of a computer. Even my old Palm 3 only had a complete loss of data once and then a sync brought it all back.

How long does your secondary battery last?

If it's SRAM and not DRAM, it can keep state on 1 micrwatt of power, which is miniscule for any battery. Memory can't be read on that power level, but it'll maintain its current state. So, as long as you have a battery, or even a capacitor large enough, it'll survive long enough to change batteries.
