Ag2 wrote a nice application, battery-status, that sits in the background and periodically records the battery charge to a file. It is described here:

http://www.internettablettalk.com/fo...ad.php?t=14115

I wrote an application, battery-graph, that takes that output and draws a graph of time vs battery charge. A typical usage is:

battery-status -d 10 > /media/mmc1/battery.log &

then wait a while, and run

battery-graph /media/mmc1/battery.log

You can download battery-graph below. I've also written a replacement for battery-status called battery-info. In addition to the battery status, it displays the temperature, network activity and CPU speed. Battery info also has the option to display process activity (-p flag). This requires rps from http://www.makikiweb.com/n800/downlo....2.7.armel.deb .

can you put a screenshot? does this show REAL battery life?

Here's a screendump. I'm working to find out why my battery starts draining quickly after its half empty.

heh, im tempted to suggest that this should be integrated with pybattery

OK, I am SO trying this app. Today, my battery died in 2 hours, while it was not being used!

i just wish that one had a working powertop variant available.

i know work have been done towards it but i dont recall there being news about a fully working version...

Ok, I did not use this program per say, just the battery-status. I used an time span of 10 minutes, nothing was running except personal launch, GPE summary, The IM client, Xterm, and OMweather. WiFi was on, Bluetooth was on, GPS off, screen off, nothing was being used. It was basically how I always leave it in my pocket.

I was shocked and amazed. It only lasted 3.5 hours with a FULL charge doing nothing!

Also, it just dies after reaching 40%. That was interesting, because bluechalk's did something similar.

I am going to try the same test booting from flash, with absolutely nothing except battery-status running, to see if there is a difference.

How can I stop this madness!

hmm, battery-graph complains that the file holds no battery-values, when it clearly do...

yes i get the same, here is an example input file that the program says does not contain battery values. Maybe a verson problem with battery-syatus ?

Would be interesting to save the current cpufreq value at the same time as the battery level is taken, might help in tracking down whether battery life is down to a dead one or some app not behaving.
