High Battery Consumption in Standby - Page 10 - maemo.org

Juhgu | # 91 | 2011-03-14, 23:35 | Report

Uninstalled catorize - had no idea it could cause battery issues until I read the forums - and battery life significantly improved.

Here's a battery graph from yesterday, just for reference. With no use and internet connection off your phone shouldn't use more than 10-15% of battery per 24 hours. (I guess?) I bought my phone when N900 came out, 15 months ago or so, and it's been in heavy use ever since. I'm quite happy with how well the battery still performs.

(The little notch there is from actual phone use.)

hi guys,

my battery lasts less and less in the last time
can someone check my powertop output?
( Offline Modus after an Restart )

btw. what the hell is the fmtx process while in offline modus?

cheers

this really sucks, any ideas?

I experienced similar problem with my N900, eventually I noticed that anytime I start the internal browser, the battery consumption peaks afterwards, even after closing the browser. So anytime I start the browser I had to restart the device to prevent the high power consumption. So what I did was to download a third party browser which I now use and I stopped using the original maemo browser entirely. Now my power usage has improved and I get longer battery time.

hi,
i have tested my device after a power-cycle (with battery removal).
the results are more than depressing. i can't say that kp49 is 100% responsible for this.
so if it's so, sorry for off topic, but maybe someone can help me to get a working device back.

i have charged my device till 19:00, the battery lasts till 04:00
9 hours in offline mode with obviously no cpu usage and no usage

what the hell is going on with me device?

i performed powertop befor testing, the output seems more than nice:

^ kp 49 was responsible in my case.

had no problems with 48

StocChr | # 96 | 2011-11-30, 08:19 | Report

and what was your solution?

vi_ | # 97 | 2011-11-30, 09:27 | Report

First off all make sure you have 'pastebinit' installed (apt-get install pastebinit)

1. Put device in offline mode.
2. Turn off device.
3. Remove battery.
4. Insert battery.
5. Power on.
6. Stay in offline mode.
7. Wait 4 minutes (for device to settle).
8. Run this code as root:

Code:

sleep 10; powertop > ./out; powertop >> ./out; powertop >> ./out

9. Immediately lock the screen and leave it for 5 minutes.
10. Connect to the internet and type in:

Code:

pastebinit ./out

11. Paste URL here.

Will you give me some hint on how KPS correlate with the fact that:

# per |OFF: 0%|RET: 0%|INA: 0%| ON: 100%| now

ON)
# core |OFF: 0%|RET: 0%|INA: 0%| ON: 100%| now
