oh, and it's a feature because it saves power and makes the device more responsive. if you still don't get it... ?

Before the CPU could be 90% off while charging. Afterwards it's ON 100%. Whether it's at 250 or 500 MHz isn't that important...
What it means is extra 80-100mA load, or a 10% reduction in charge rate.

I think some of you are having some problems that aren't related to PR1.3 exactly because I have 2 N900 that I updated to PR1.3 and when I charge them the CPU wont load even to 10%, all is peace and quietness
Even my battery last longer than undervolting with kernel power. At first I did not believe it, I just update one N900 and test it while the other was still on PR1.2 but later I update the other N900 and it is exactly equal, battery last longer and CPU quiet while chargin.
NOTE: I can give you pics from battery graph to prove it if you want.

PR1.3 introduced a "feature" where cpu never goes below 500MHz when charging.
But yes it sucks and I do not notice kernel-power would fix it.

If you use default voltages, there is quite a difference between power used between 250 & 500mhz.
If you use power-kernel and ideal profile, there is ZERO difference, so you're making things worse by running at 250.
Maybe Nokia learned how to make phones and charge batteries with their 38 years of experience, maybe the battery can only charge at a certain rate which can be easily met, on average 500mhz load, when plugged in. Maybe you guys should test or research this stuff before complaining...

i think some of you guys are confused.
1- the 500mhz minimum while charging were always on n900 yes even with pr1.1
2-if you charge your phone its still in idle what takes 0mhz,it only goes to 500 if you play with it
so pls stop sharing FUD its harmless and even not worth to discuss
thanks

500mhz is fine
800 is fine
it's not going to use more power or get hot
if its running at 500mhz and using 50% cpu it is less efficient than running at 1000mhz and 25% cpu because the lower the % the more often the cpu can power down completely.
oh, and it's a feature because it saves power and makes the device more responsive. if you still don't get it... ?
the original post complaining about 100% cpu usage, well, that really is something wrong. and nothing to do with the rest of the comments here (almost). at least that is how i read the post. maybe they could be more clear about the problem.
