Re: High Battery Consumption

btw.
"normal" idle usage is something like in this pic on right side:
http://img684.imageshack.us/img684/9...0100412103.png
Still some spikes from cpu that could be probably from some daemon.

Just for reference.

.edit
And when comparing remember to check x-scaling

Re: High Battery Consumption

BIG NEWS

after backup the full system with backupmenu and multiboot i had to reflash the stock kernel via maemo flasher

i will post the powertop output in a few minutes

i think we got it.... stay tuned

Re: High Battery Consumption

can someone of the pro's tell me, if the output is normal yet...
i've already made friends with a reflash,
now i'm in the conflict of conscience!!

any hints what's now to do?!

Re: High Battery Consumption

Run powertop couple of times (to minimize margin for error) to get idle wakeups and use n900 for awhile and run powertop again. I mean that test your setup for couple of days before making any conclusions.

.edit
From here you can look for references:
http://wiki.maemo.org/N900_software_...ement#Powertop
I would say that something like ~500 wakeups and mostly in C4 state is pretty much ok for completely idle N900. This is not scientific measurement just stuff from my head.

Re: High Battery Consumption

ok, i will uninstall not used things
will set up the kernel power and will observe the system with powertop and batterygraph

btw. how to clean up the maemo-user-package-list

Re: High Battery Consumption

Please dont tell me you re-flashed both emmc and rootfs then DID NOT restore with backup menu?

Re: High Battery Consumption

i created a backup with backupmenu
then i flashed only the kernel

Code:

flasher-3.5 -F <firmware-image> --flash-only=kernel -f -R

no emmc no rootfs reflash

Re: High Battery Consumption

after several problems, i did yesterday night a full reset.
i flashed the eMMC and the rootfs

i installed all programms, overclocked, cssu, ...

Re: High Battery Consumption

yes. now it seems to stay at C4 level as it should when idle.

This is my powertop output in case someone can help me find what drains my battery.
it's not a serious situation but I feel my battery can perform better (around 15% more)
