High battery drain in standby

Priority: minor Milestone: Android 2.3 C
Component: Android 2.3 Version: Android 2.3 - Anoa

Description (last modified by divx118) (diff)

The Device goes to "Deep Sleep" (confirmed via CPU Spy).. but the battery drain in standby is at about 25%/24h. In the original firmware i can switch on "Tiefschlaf" (translated: Deep Sleep). In this state no event can wake up the device. The device looses in this state <5%/24h.'

  • status changed from new to closed
  • resolution set to fixed

The device did toggle wakeup/sleep when in deep sleep. I now have disabled loading of the modules when adb is not checked. This should improve battery life and will be in the next release. However if you enable adb it can't goto deep sleep, but I think that is not a problem.

Reopen when battery drain will still be huge on the next release.

Which device do you have?
On RC2 Bull release?
If on RC2 Bull did you also flash the new kernel and initramfs which is included in the downloadlink for RC2 Bull?
Have you disabled adb?
What is consuming your battery?

@airwolf1544 Thanks, I still have to look at that one. Next build the fix mentioned there will be in.

Oops wrong textarea.

Ok pushed the fix mentioned to our git  https://www.gitorious.org/openaos-cyanogenmod/device_archos/commit/0e555b063f96f4f40aa92922be1067f3b9f7aa87 . I leave this ticket open for now, until we have some positive feedback on the battery life improvement.

Reverted that fix. It didn't work that well.

I agree : except after first boot, ginger refuses to go to deep sleep (archos 5it, 500g hdd). On froyo, I use a workaround :I press power once> screen off, then power again>screen on but locked, then let the device go to deep sleep by itself.
On bull rc2 (december or april release), no slide lock (or : I didn't manage to make it work !) and no deep sleep. Only solution : switch off the archos to save battery...

IMO problem with hdd version devices is that it can't goto sleep because the image file is on it. So the hdd is constantly in use.

It looks like the good explanation. However, isn't it possible to make the hdd-device working as in the froyo version ? I use the wewewi-mod froyo, with a storage of 1Gb for applications, and the deep-sleep works fine.
Sorry if my remark is stupid due to technical difficulties...

Any link so I can take a look by what you mean by the wewewi-mod froyo, maybe I can port it to CM7. That would also be nice for the A70it hdd versions.

This link is good but slow... It contains an alpha5 modified froyo : wmod-rc2.
It needs to be verified, but I believe the deep-sleep began to work well after flashing with bull-rc1 kernel.

Hmm that is just a build image file I would need the source code. I will see if I can find something in our source, however I don't own any hdd devices (gen7 or 8) so it will be hard for me to see what could be wrong. No promisses.

Having a deeper look at my archos' behaviour, it seems that it doesn't really go into deep-sleep : it wakes up from time to time (power led blinks on and hdd starts a short time)and stops immediately.
The deep-sleep feature doesn't seem to be possible on other firmware than the original one...

Yes, one of the problems is wifi. It doesn't goto sleep properly. I am still working on that, but have very little free time lately.
