I was wondering if there is an application...that will tell you the amount of time left you have of battery power....instead of percent....voltage...or graph....i think what is more important to us...is how much TIME do we have left of power...anyone know where one is?

Time left is depends on the rate of consumption, which varies according to the current task, so time left would either constantly change, or be meaningless to the moment (damn, I sure do love a good run-on sentence :D ).

The amount of time left depends on how you use your CLIE.

Without history and instant reading on power consuption, it would be pretty hard to estimate how much time you have left.

I find the power remaining % not very reliable.
The % slowly climbs up (without recharging) from 35% to 60% once I stop using the WiFi card !!

The time remaining on my Sony Cybershot camera isn't very reliable either..

You would need an intelligent battery, as the usage is variable and really no accurate way to tell. Yes, you could get a time at any given instant, but it would be continously changing.

Sony Stamina batteries are "intelligent batteries" aren't they? My Cybershot uses those...
Still, they are not very accurate.

They are only accurate at any one given moment, reason is the battery can't guess what you intend to do next, so the situation is fluid, unless it's a constant steady drain. When I say accurate, I am not speaking of seconds. The whole point is that unless the battery is in a controlled enviorment under controlled conditions. It's reported life will continually change, so there is no real way to measure actually how much real time would be left.

Basically I agree with you :)!
