Cell Standby Bug?(PMID701c)

[artistlogic]

After noticing the bars/nosignal indicator at the top bar I downloaded an app to put the tablet into airplane mode. The bars was successfully replaced by the Airplane icon. The tablet has been in airplane mode for over a week, however when checking battery stats, Cell standb is still taking 83% of my battery somehow anyone else experiencing this?

[sabercatpuck]

where are you getting the stat?

i couldnt find a battety usage chart on the tablet so installed power tutor. it doesnt show any cell usage on mine, though i hade changed the name of the phone.apk to phone.old. then eventually made it through the endless series of force closes to finally shutdown and reboot.

The stats in your app are only measured from the time you installed it. The stats I'm using are built into your device, but hidden. You can get to them using Any Cut as recommended by Bob. Install "any cut" from market, run it, choose new shortcut, choose activity, then Battery Usage and it will create a shortcut on your home screen for you to access it.

some good news then...

i am showing only wifi 47%, device idle 38%, and display at 17%. nothing saying cell standby, so that part worked. now we just need a way to do it without the real pain in the arse constant force close i got until i rebooted. took some really fast finger work to hit the yes i want to shutdown button

[artistlogic]

These are what mine look like.... do you still have the Bars icon at the top?

[sabercatpuck]

Bars with an x

I have bars with an x over the small ones on mine.

I assume there would be a way to get in with ADB (I haven't done that much yet so didn't know for sure) to try changing the name from Phone.APK to Phone.OLD. If i remember right then you would be in debug mode so issuing the reboot would go smoother than when I did it with Root Explorer.
(Side question, is your screen cap from an app, or is it built in?)

This is very strange, why would airplane mode use more batter than nonairplane mode? The screenshot app I use is called Screenshot ER, it works pretty well, i like it

In electronics we have a term for this PFM

Pure Flippin (Or insert your favorite other word here) Magic. This one might have to go down in the I dont know why it does it but it does category. I think the bigger question though is how to be able to change the phone.APK file nme or delete it, while then issuing a reboot command behind all the froce close messages since we definitly are not going to be trying to make a call with it, it can definitly go. Obviously an easy thing to do when creating a custom rom, but I dont think we want to have "Now realllllllly realllly fast click the power off button between force close messages" as a step in the procedure , but getting rid of it like Finless said is definitly what needs to happen to fix the bug.

Or you could probably just use the reset button to reboot...?
Btw, are you referring to /system/app/Phone.apk?

[sabercatpuck]

Yep thats the one

System/App/Phone.APK, yep that is the file I changed to Phone.OLD. Finless mentioned doing this in the Sticky. I noticed in the sticky that N4RPS had just posted that he tried that as well and hit the reset button to escape instead so we do have a test case for this, just not sure what the result is. I sent him a PM to get clarification on what happened when he did. Hopefully it just reset and didn't do some kind of data wipe.

[whoshotjr2006]

not sure what to do about the cell standby, but we could always mod framework to show a blank icon where the signal bars with an x are, at least put a small blank space so we forget its there lol

[Finless]

We need to edit init.rc in boot.img to turn off the service. I am new to that part but I think I see where to do it.

However later if this things supports 3G USB sticks, good chance it will break them.

I was able to change Phone.apk to Phone.old and reboot, and after about 24hrs, Cell Standby was gone from the Battery Use screen, and the battery life is NOTICEABLY longer now. I left it sitting on my desk fully charged for about 12 hours, picked it back up and was still at 98%. Before fixing Phone.apk it would have been nearly dead. Score another one for Finless Bob (and saber for bringing it to my attention)
I recommend EVERYONE do this asap

Tested it out on the new one. Better way

It does work out better to do it through an ADB shell
If you start the shell up use the following commands (note case sensitive names)

cd /system/app

mv Phone.apk Phone.old

reboot

It still goes into the infinite loop of force closes but since you are shelled in through ADB you can issue the reboot command to stop it.

EXACTLY! Anyone wanting to play on ROMs and stuff, in the end get ADB working. It's not that hard and in fact I have a way to give you the ADB command tool without installing the entire SDK or the Java JRE .
