doesnt lshal | grep batt do that already ?

it shows the remaining time left . or am i missing the point here ?

Re: Nokia Energy Profiler for N900?
 

Nokia Energy Profiler does a lot of other stuff too. I'd be interested to know if there are any similar suites for Maemo for the features other than power usage, such as recording CPU usage, transmitted and received data speeds and amounts, signal strengths and disk and memory usage?

Re: Nokia Energy Profiler for N900?
 

And does the script work? Can you get an estimate of time left on the battery?

There is an app called battery-eye in extras-devel. It's graphical display of your battery drain.

Re: Battery drain display
 

It must be possible! you guys are thinking to difficult here. it has nothing to do with all these things you are mentioning!

The n900 can get the current mAh every second or so. lets say you let the n900 log the mAh every second. so you can register how long it takes to drop 1 mAh lets say this takes on average use 30 seconds. then a fully loaded battery of 1320 mAh wil last 660 minutes. If the n900 takes this average every 5 seconds instead of 30 then you can calculate the exact amount of time left.

And offcourse when the time left is 660 minutes and then start dosbox it will be less. but if it updates every 5 seconds then within a minute the n900 will change the amount of minutes left to for example 60 minutes. when you close dos box it will rise again.

But i dont care!!! it would be awsome that when you are playing a game or browsing the internet, you can look at the time left and see how many hours you can play this game. or browse the web.

These values shouldnt be values of avarage use through the whole battery cycle but everages taken every minute. this way you can get an accurate battery time left on whats happening on the n900 at that specific time.

An average battery time is not interesting because it will never be acurate. but a battery time that gives the use of the mAh from the last 60 seconds will give a very tigh prediction of how long you can use the n900 till it dies out while keep doing the same business on the n900.

i hope everyone understands!

MAN!!! if i knew how to write code i would have built this allready. its so darn easy to make... but i dont know how to make an app. maybe someone else can make this.

Install kernel power (current version is 48), then search for i2cget in the forum. Those can provide time left as well as current usage.
