This is crazy! I should be seeing < 10 mA. Are the power49 wifi drivers munged?
Testing without wifi gives a fairly bumpy power consumption between 17 mA and about 90 mA. Note this is wifi off, screen off, measured with the bq2700.sh script. We appear to have a hungry wifi driver here. At these rates, a wifi-connected idle N900 will discharge in 6 hours, instead of lasting for days.

Connecting to regular wlan: 22-25mA idle (no pin, screen off)
Connecting to ad-hoc wifi: 200mA idle (no pin, screen off)
[edit: searching for threads on wifi powersaving in ad-hoc mode now]
So ... 22-25 is no where near the best i've seen on an idle device with wlan, but it aint bad! That's somewhere around 160mAh over 8 hours, or maybe 15% battery tops. Sorry for the scare!
(Edit with wifi off i see 17-18 mA, which is higher than the best value i got on stock kernel which was 5 mA)
Thanks!

mplayer output is smooth when loading a ULV profile with kernel-congif
mplayer output is smooth when loading a LV profile with kernel-congif
mplayer output stutters when I load a DSP profile with kernel-config
mplayer output stutters without using power-config to load any profile, it's enough enabling smartreflex editing the pmconfig file
As you know, I'm not an expert. I did 4 times the tests, every time reflashing the device, with installed only PK49 and the latest testing CSSU. I tried once without CSSU too, things gone in the same way, mplayer output stutters when there is smartreflex enabled.
Can you guys try it too? If u have mplayer+kmplayer installed, it should take only few seconds of your time to load a dsp profile and start a video with mplayer

@Pali - isn't it time KP50 to enter extras-devel?

Kp49 with CSSU, smartreflex and DSP enabled via pmconfig. No stuttering playing a vid through KMplayer for me.
Others can correct me if I'm wrong as I'm no expert either but the way I understand it, each phone is going to respond slightly differently to the kernel, so what may work best for mine, won't work best for yours.
I use my phone as an mp3 player via mediaplayer for a few hours on the road each day and notice that my battery life is better in that scenario w/o KP49 booted up. My view is if one stutters and the other doesn't, stick with the one that works :-)

I only have to ask you if you are sure that kmplayer was using mplayer for decoding the video. I ask you this because with smartreflex enabled gstreamer works great.
