Diablo Update Fixes Battery Drain? - Page 8 - maemo.org

drain. Only a reboot worked. But I'll have to look at that
more closely to see if it's really true.

I wonder, does anyone else see this behavior?

I have similar experiences. When moving away from WLAN something not visible in load-applet is using a lot processor cycles resulting in battery drain and making network connection selection unusable. Only way I have found to solve the situation is rebooting apart from manually disconnecting from the network prior to leaving WLAN coverage. I have yet to try iwconfig method mentioned above.

This does not happen every time when changing locations and started happening just a few weeks ago. I have had Diablo on my N810 since its release.

I don't see that - for me it's the wireless chip itself that is
draining the battery (because power management is off) -
the processor is not working unusually hard ... (verified
by top, which, by the way, shows that browserd is not
my culprit).

Hi,
this battery drain bug has been pestering me since I did the first SSU (to version 30-2) on my N800. No similar symptoms before the upgrade. In order not to go insane because of the present unreliability of my N800 I'm trying hard to pin down the bug with a hardware current monitor attached to the battery. I posted a HOWTO guide on that topic in the hope that it may turn out helpful to "the IT community". See my post in the other battery thread:

cheers,

Well, let's just say it's not happening to me anymore... but I have not investigated the issues behind it (nor will I, sorry) and sooner or later there will be another Diablo update.

Hi,

the wlan not shutting properly down issue occured again today (just as I thought everything was going well) and the power was about to drain...

This is what I did:

connect to my wlan, synchronize data with unison, run microb, close microb, disconnect from wlan.

This is what iwconfig says after I disconnected from wlan. Note that the power saving is set to off.

Code:

~ $ iwconfig
lo        no wireless extensions.

wlan0     IEEE 802.11b/g  ESSID:"mylan"
          Mode:Managed  Channel:0  Access Point: Not-Associated
          Bit Rate=0 kb/s   Tx-Power=19 dBm   Sensitivity=0/200
          RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality:43/0  Signal level:-48 dBm  Noise level:-91 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

and this is the relevant part of dmesg

So it seems that the WLAN still trys to do something which might cause the drain observed here and elsewhere. Still not sure what triggered this behaviour.

Can you post some of your readings at various levels of the backlight from on to half to 1/4 to off? Bluetooth on/off to offline mode?

I learned to do without so bright a picture and stretched the battery out many hours...no matter what the radio transceivers were doing.

I looked at some of the 4" display backlight LED specs on new LCD units. 7 bright LEDs were drawing around 800ma at full brightness! No wonder the battery croaks....

why i can't use the iwconfig command? do i need to install any tool?

By the way, I already so call "solved" the problem on my own way!!

I have to power-off the device totally everytime after use

(excluding watch video or listen music on canola2) which can use for 2-3 days without charge.

I've tried the following way but no success:
1. switch off wireless (offline mode);
2. disable the RSS auto-update;
3. remove all the configuration for Modest email client;
4. remove everything from the home screen, except wallpaper;
5. Replace the internal SD card and reformat the external SD card;
6. Disabled the Metalayer_crawler;
7. Reboot the device after use or full-charge.

But my N800 still getting hot and drain my battery within 4 hours.

Nokia, please solve this problem before release the new N900 or whatever NIT model. or call it NID - Nokia Internet Desktop

If I don't switch off the power after use, basically this device is not a mobile device, I have to always plug-in the power, at home, office or car....

you need to be root or have root privileges

(you have becomeroot package?)

The bug occurred yesterday under the following circumstances (non-reproducible, though):
N800-diablo.30-2
I did a usual session; logged on to home WLAN, started internet radio from home applet, ssh'ed to local gateway, VNC'ed on the local network, browsed a couple of external sites. Then I disconnected the WLAN using the statusbar icon (w/o stopping the radio streaming). An error message "connection to stream lost, reconnect?" popped up. I clicked on "reject" and then the current consumption went mad to at least 300 mA. I instantly ran htop only to get an indication of 10% CPU, 1 process running: htop itself. Locking the screen obviously didn't help. The supply current went back to normal when I forced "offline mode" in that state (although the status bar icon showed no active connection anyways).

Following scg, I'm posting a portion of my dmesg log. The second "shut down softmac" message is most probably the "forced offline" step. However, I don't fully understand how that "softmac" thing works. I hope that it is not anything similar to those horrible "soft modems" for windows?

/b.
