Comment(by lala):

 I left my phone connected to the wall charger and it happened again over
 night. In the morning the battery was 95% full (batmon). I've seen that
 "SDIO Helper" also eat around 5% from CPU. In the /tmp/x.log I've seen
 "CHANGE PW SAVE MODE TO 3 / 4" between a lot of "...caches flushed.".

 So, by doing nothing I can reproduce this in less than 23 hours. I mean,
 no gps activated, no gpsd started, no wifi, no bt, no phone calls received
 or initiated, not playing with accelerometers. Just lunching clock
 (qtopia), Settings-exposure (non-stop), batmon, dmesg, htop (non-stop),
 xterm (non-stop) and pluging/unpluging into/from usb.

 rootfs: Om2008.8-update (updated about 3 weeks ago)
 kernel: Om2008.9-gta02-20080916.uImage.bin (has the same md5 like
 Om2008.8-gta02-20080903.uImage.bin)
 uboot: gta02v5_and_up-u-boot.bin from daily builds (2008.09.30)
