Device Standby 76% on Craig Netbook running Android 2.2

[AngieR]

Got a Craig Netbook CLP 281 the other day with Android 2.2 installed. Actually, it replaced a previous Craig netbook that was defective which was also running Android 2.2. But it must be a different build because in the previous Android 2.2 I didn't have "Device Standby" in the "battery usage" listing. It just had Display (using about 15% of the battery) and WiFi (using about 12%) Ok, this new "feature" is using 76% of my battery life. And last night, when I used the netbook on a fully charged battery, I noticed how short a battery life it had compared to my previous Craig Netbook (same model) which got me to investigate. In Settings/About Device/Battery Use that's when I found this entry "Device Standby" describing itself as the amount of the battery that is used by cell radio. But I have a netbook, not a phone. Anyhow, it suggests to put the WiFi settings in "Airplane Mode" but that doesn't help but it actually went UP to 83% usage. I don't make phone calls on a Netbook so why is it looking for cell towers (as I'm understanding it). How do I disable this? I tried uninstalling "Dialer" but it's a pre installed app so you can't uninstall it. I googled the matter but all the suggestions were for people having this problem with phones, not Netbooks. When I followed a few of the ideas, the menus on my Netbook were different so options were not there like on the phone menus.
And I tried that thing using "Calculator" and entering some "secret code" !+!+ 4656+!+! (or something like that) but I got an "Error".

Does anyone have some information about this matter? Also, is there somewhere that I can upgrade a Netbook running Android to the next firmware update? (if it exists)

The build of this Android 2.2:
Generic English 2.2 Froyo Ver 1.5.3 201108190.062300

Be great if someone has an answer to this question. I see a lot of people with this problem Some say it began in November with an upgrade. I think my first Craig was a July build. Looks like this is an August build (if I'm understanding the version info correctly.)

Anyhow, thanks,
Angie

First of all "Wow!" I can't believe not one reply. I ran a search for something unrelated tonight and this post that I did back in December came up. OK so I'll post a reply.

I found the solution for me. Worked for me on my Craig Netbook CLP281. I was desperate and actually didn't care but for you, please be careful and proceed with caution. I don't know about doing this on a phone though.

1) I installed z4root.apk and rooted the device. Very simple to do. Just select "Permanent Root" when you open the app. It will reboot your device after the rooting is finished.
2)Then I installed Terminal Emulator (or you can do that beforehand to be ready) I typed in the letters: su and hit "Enter" on the keyboard. The $ sign will turn to a # sign if you are rooted.
3)Then the SuperUser app will come up and ask you if you want to give Terminal Emulator superuser privileges. Click Yes. Then I removed Phone.apk using Terminal Emulator and a code I found online. Here's the code I used:

My instructions will be in ALL CAPs so you can tell the difference.

IN TERMINAL EMULATOR SCREEN TYPE THE CODE BELOW. BE SURE TO MAKE NOTE OF ALL THE SPACES BEFORE THE DASH, THE LETTERS AND THE SLASHS TYPING IT EXACTLY OR COPY AND PASTE IT AND SAVE IT TO YOUR DEVICE IN A TEXT FILE WHICH IS WHAT I DID AND THEN COPY AND PASTE IT INTO TERMINAL EMULATOR.

OK, TYPE:

mount -o remount,rw -t yaffs2 /dev/block/mtdblk3 /system

HIT ENTER SOME WORDS WILL COME UP AFTER YOU HIT ENTER THAT MAY DISCOURAGE YOU LIKE IT'S AN INVALID ADDRESS OR SOMETHING LIKE THAT. DON'T REMEMBER WHAT. BUT JUST PROCEED WITH THE NEXT CODE BELOW.

THEN TYPE:

rm -r /system/app/Phone.apk

HIT ENTER

An error message comes up about the application trying to close and won't go away. Just hold down your power button to shut down your netbook and when you reboot, Phone.apk is gone and so is Cell Standy.

I don't think I'm coming back to this posting again. It was by accident I came back to it tonight. So if anyone asks me a question about this, I apologize if I don't get back to you.
