You could charge it while testing. But this would generate more heat. On the other hand this may not be bad since you dont want you device to fail in Summer just becuase you finetuned it in Winter.

Stick my name on the testing list.
Ive got insurance on it anyway

all this fuss over, over clocking. it'd be a waste of time for a dev to do this especially seen the profile's make almost no difference to battery life
its not the cpu thats the problem really.
if you want to have a low voltage load because you think it'll give you more battery life, try dimming the screen and disconnecting from gprs/wifi and turning bluetooth off instead

would be really nice if there was a automatic voltage test app.
i had probs with overclocking too.my n900 runs at 850 and the lv profile stable like a rock but if i tried 900 everything was ****ed up.
i tried lv and xlv and both didn't work.
would it be possible to use the default nokia voltages at 900-950 mhz?
i could spend a lil bit battery if my n900 could run stable at 900-950 mhz

Have you tried looking in "dmesg" after taken a picture or done a video? It could be working but also generate looping errors that depleats your battery faster. I think that however this will become it will need or some way of listening on error output. I am not sure "dmesg" would be enough. If we could find out the precise error that occur just before reboot.. then we will be able to make a more robust script/program.

A nother problem with the "reboot" strategy would be what to do if the battery gets fully depleated. Reboots takes about 10% battery.
This means that -- depending -- a reboot can cause relatively unpredictable results in the battery % value. Sometimes it will go down 10%, sometimes up... But 10 reboots in under an hour won't drain your battery completely, no matter how much a single reboot "drained".
It -will- take some power though, but considering that you should be able to run fully loaded for 3-6hrs(depending on condition of the battery), it shouldn't be -that- much of a problem.
Charging it during the test probably wouldn't hurt -too- much, and charging it before the test would also be a good idea.

As far as battery life goes, I do agree with your statements - I find significant standby time increasing by going into "offline" mode(as is expected).

Depending on load, even moderate OCing can -increase- battery life, as it ends up spending a shorter period of time working, and more sleeping(or, at least underclocked). However, running something that maxes the CPU constantly will give you worse runtime... But the same thing happens at 600mhz, so..
A nother problem with the "reboot" strategy would be what to do if the battery gets fully depleated. Reboots takes about 10% battery.
