Guest Winston69 Posted October 21, 2010 Report Posted October 21, 2010 Seems to be the cause of my battery being eaten alive I'm going to rename it using root explorer and report back if it causes much trouble but this defiantly seems to be a battery drainer Anybody know exactly what it's doing?

The file is used for the compass and rotation sensor. If you don't use either very much you could try doing this from a command prompt using ADB adb shell echo 250 > /data/delay[/codebox] Be warned! a. This is likely to make the compass and rotation sensors quite unresponsive. b. I haven't tested this on the SF but I know it worked on the Hero when I had the problem with a previous ROM. Do a clockworkmod backup before you try, just in case :P

Would changing the delay as you mentioned above have an effect on the gps also?

Try it and see :P if things go wrong just restore your backup, although just deleting the file the commands I posted creates will undo any changes that it makes to your system.
Guest meinnit Posted November 11, 2010 Report Posted November 11, 2010 I have also noticed that this process is taking up between 2% and 5% CPU constantly when the phone is awake. I used top via adb to confirm that it wasn't consuming CPU when on standby. Don't understand how a process can be allowed to use so much CPU! Doing a search on the net confirms that jsplace's comments are correct. Using Spare Parts I've noticed that this process is one of the main users of CPU time. Might be worth writing a script to disable this process whenever GPS isn't in use as it only seems to affect GPS (compass probably). It may also control screen rotation from comments I've read but I'm sure we could live without that to save ourselves some battery juice!
Guest meinnit Posted November 11, 2010 Report Posted November 11, 2010 I am using MCR r4 btw. Not suggesting that the ROM is to blame but was wondering whether other people are experiencing the same problem and to try and eliminate the problem. I didn't noticed until I did a top command via adb!

Could those who have identified this problem perhaps turn off screen auto-rotation and see what difference that might make?

I don't use auto orientation change. Do you get this problem at all? Just for info, I am using LauncherPro.
Guest steff.jay Posted November 17, 2010 Report Posted November 17, 2010 Hey you, as I use 'watchdog lite', I get alerts, if any app uses more then 70% of the CPU. At the moment I have about 15 times a day the alert belonging to AKMD2! Even if the display is turned off. And also it constantly takes 6-7% of CPU - the whole day! So, what shall I do to fix this? - disabling auto-rotation brings max. 1-2% And I don't know adb (so far), so I would be pleased of any other solution/idea. thanks
Guest meinnit Posted November 17, 2010 Report Posted November 17, 2010 My akmd process only uses CPU when phone is awake.
Guest steff.jay Posted November 17, 2010 Report Posted November 17, 2010 My akmd process only uses CPU when phone is awake. well, I thought so too, but get the named alerts even if the display is off (but I am charging atm - is this the cause?)
