Methods for determining battery drainage / cause
Hello Maemo, I've done a few searches and haven't anything really all that comprehensive. Does anyone know of an existing list, which indicates which apps are known to drain battery life in ways outside of their function. (ie, programs continues to scan while closed, draining battery prematurely, etc.)
My N900 is having some real drain issues lately. I've been using a combination of turning the cell radio off, disabling wifi, and forcing deep sleep in an attempt to get more battery life, but I'm still loosing anywhere from 8-12% over the course of a few hours, while the phoen shouldn't be doing anything. Thanks for any help. Edit: I'll be editing this post with info I find that is useful to said subject. As I discover apps known to do this I'll put them below (I'll try to provide links to the source where I can): - Personnel IP App (circumvented if phone is rebooted on a daily basis) - All Daemons (apps ending with a d, this is not so serious, as their use is mostly very little, but can build up over time, especially with alot running at once) This includes batterygraph and eye. -fmtx widget - There is a know hildon bug associated with categorize and apmefo that has to do with reorganization items, and quickly moving between folder items that causes hildon.desktop to continue to run at about 1-5% cpu load. Rebooting or killing hildon.desktop with htop fixes the problem temporarily. - MaeNotify appears to cause an excessive amount of drain as well. Edit: Powertop is a useful program to investigate in depth power use. See page 3 for it's use and installation. Edit: Tho shared a method he uses to track down battery drain issues. Seems very efficient and practical, here is a link to the comment: http://talk.maemo.org/showpost.php?p...4&postcount=52 2d |
Re: List of Apps known to drain battery?
I can see a similar problem. Once I reloaded my phone – turn it on and do nothing, my battery drain looks great. But as soon I’ve been once in the INet (Wifi or 3G) or answered a phone call, the battery drain looks much worse than before – this is somehow strange… (running Titan v37 kernel).

Re: List of Apps known to drain battery?
It would be handy to get a list of apps that cause drain or people suspect to cause drain, would'nt mind trying to find a list of apps that take space on your rootfs as well, so we can try to encourage the developers to optify them, i only have 59mb left, and have no idea which apps are taking the room up.

Re: List of Apps known to drain battery?
a) 59 root is fine
b) if we had a list they would never make it past -testing c) do you have extras-testing and -devel enabled? d) you'll have to cook your own watch before. Get a monitoring app, get conky, get battery-eye and check to see what it does when it does it. Then you can be helped. Repos have some 5000 packages. More specific please? |
Re: List of Apps known to drain battery?
To start to pinpoint this please provide information on which repositories you activated and a list of installed apps.
The list you get by this cmd in xterminal Code:
maemo-list-user-packages Code:
maemo-list-user-packages > /home/user/MyDocs/.documents/Installed_Apps.txt |
Re: List of Apps known to drain battery?
I have the following repo's activated:
Both Nokia repos ovi repo maemo extras maemo dev mozilla And below is the list of installed apps: Code:
3g2g-mode-selection-applet 0.4-2 user/desktop 64 I will also add that my N900 has had the wifi bug since I've gotten it, and 1.2 has done nothing for that. (I have to reboot after using wi-fi or loose a ton of battery) 2d |
Re: List of Apps known to drain battery?
The main battery drain I have seen is yesterday when I had a Fennec/Firefox process hang and take up 99% of the CPU. It ate most of my battery in under an hour. I had put it back on my belt and the next time I pulled it out, I noticed that the device was warm to the touch, and fired up conky to see if anything was eating the CPU. Sure enough, there was that stray Fennec process...While I prefer tabbed browsing instead of opening multiple disparate windows, I am going to be very circumspect about my use of Firefox for a bit, or I'll use iceweasel from Debian...

Re: List of Apps known to drain battery?
I see you have apmefo installed, so I assume your using custom folders for your menu?
If so, there is a bug in hildon-desktop that will cause it to run at 4-9% continuously after run access the app menu. See either apmefo or catagorize threads for more info. This can cause the batter to drain rather quickly. |
Re: List of Apps known to drain battery?
For any curiou son more specifics relative to Lemmyslender's post, here is the bug tracker link for said battery drain:
