Battery percent time left?
 
Is there a way to get the actual percent of battery time left rather than hours left or days?

No, not in Maemo.

To be honest, I rather have the time left. Between so many batteries and devices, the % on any particular battery doesn't say much. Add in load changes and I rather have the device calculate it / estimate it for me.
This of course doesn't help my math skills ;)

Ah, but the Pepper Pad gives you both...

I'd like to have this information during charging. While charging it only says that it's charging, but not for how long...

My Treo 700p will tell the percent of battery left by tapping on the battery icon, it gives me a better idea how long i have left

Yes, but that's a Palm. As it hardly does anything at all, it's not that difficult to predict battery depletion.

Oh: :D:rolleyes:;)

Gripping hand: Just about anyone is better at battery gauges than the Nokia Itablets.

The battery level meter in the status bar is actually a random number generator, why anyone is interested in what it says (whether it be in days & hours or percent) is beyond me as it's usually total bo11ox. Mine can say I've got 2 hours left and 5 minutes later I'm getting battery low warnings - it's total nonsense.

It's very useful!
If the screen is lit and you can see it it means your Nokia is on.

I wrote a command-line app to display the remaining battery charge in percent.

Thanks! I will check it out, there is definately talent on this board.

Thank you sooooo much :D Now I get to check my battery status from KDE - that was one very important thing I couldn't figure out how to do. Thanks again.

Clearly you've never spent any time with a S60 phone...

Ah the joys of watching the battery meter go from Full down to 2 out of 7 bars. :)

Happily not. My UIQ P910 is amazingly accurate, though: a full battery icon means there's plenty juice on board; a black screen means I'm out.

Funny you mention that, because at least in the past, (the 700p may be better, YMMV) Palm hardware had some major limitations on battery charge detection, and the OS could only give you a certain number of battery levels (like 25%, 50%, 75%, full), and even those were more-or-less guesses based on the original capacity of the battery.

I always though the reason that battery life indicators were so rubbish was the battery technology.

something about them giving a steady voltage output for most of the time and then suddenly dropping at the end (this is by design I think). Hence, difficult to measure...
