[SCRIPT] Remove Cell Standby Service (No Effect on Battery Life!)

Please do not do this. As the thread title says, "No Effect on Battery Life!"

I know it may be too much to ask but I'm going to ask anyway.
Can you make this CWM flashable?

I know it may be too much to ask but I'm going to ask anyway.
Can you read the thread and see that there is no point in doing this?

You all should read the entire thread. This was disproved. Removing the apks don't improve battery life as the NC does not have a cell radio.

I just read 20 pages and see no proof that this does not work. Where is the scientific methodology? There needs to be two identically configured nooks. One with this hack and one without. Both need to be fully charged and then unplugged. They both need to be left running and not sleeping. Perhaps running Pandora or something. After x amount of hours their battery levels should be checked and compared.

Relying a test of a single device while in its sleep state is not sufficient. I am smart enough to know many services are halted during sleep. For all I know, the cell service might be one of them. It may only run in futility when the nook itself is being used.

Now, unless my tired missed this experiment already being done, I am left with real world experiences; albeit not as reliable as scientific experimenting, but better than a non-scientific experiment.

Also, saying that the cell service program can't drain your batter because there is no hardware may not be correct. Programs DO drain batteries. Duh, right? I would think a program that is polling for hardware but never finds it, and thus runs constantly, would indeed drain batteries... fast.

Well, if the above experiment has already been done (twice), please someone enlighten me.

I have done this basically once, i can confirm from one trial that it makes no significant difference. Although i should try it twice for proof i guess.

<sigh>

I'm going to resolve the problem of people continuing to read Post #1, think this is something worth doing, ask questions about it, and have the thread continue to pop up on my subscriptions page by finally just unsubscribing from it.

That's just sad. I don't recall ever needing to unsubscribe from a thread I've posted in before.

Edit: i had tried this a loooooooooong time ago. Came to my own conclusion. Just responding to the person before me.

Sorry for disturbing you your highness.

Okay I did and it wasn't too much to ask for

Sure. Done. My wife's NC does not have the phone apk's removed, mine does. Hers shows the expected phone/cellular stuff in Spare Parts, mine mostly shows Android System as the top consumer.

Her NC uses about .2%/hr when it's asleep, or around 20 days standby time. Mine is the same when I disable my widgets.

Have you tried the expirement with the nooks NOT in sleep? That is the real test. I would expect that services such as the cell would be dormant, as it is sleeping.

If not, than your expirement is invalid, scientifically speaking.

Your argument is invalid, as what's showing up in Spare Part is Partial Wake Lock, which is only when the NC is asleep.

But anyway, yes, both of ours use approximately 8-10%/hr when in use. I could sit 'em side by side and measure them out exactly but that's pointless.

You feel free to do it and let us know..

I appreciate what you are saying, however I have searched this entire thread and cannot find the write up or data from your experiment. I do not know if both your nooks are identical in their model, firmware, installed apps, running services, etc. That alone means your results could be invalid. I don't even know the procedures you took in your experiment, save that you tested them while they were in a state of lower power; which is not the state they really need to be tested in. And of course I have not seen anything about your experiment being replicated. That alone invalidates ANY conclusions you could draw from whatever experiment you have done.

The fact is any experiment needs to be done according to scientific methodology.

First, your control group MUST be identical to your variable group. Any failure in that and you have literally lost control of the experiment.

Second, the experiment MUST be replicated using the EXACT same experiment. Failure to do so makes your initial results inconclusive.

These rules are not subjective or prone to opinion. These are established guidelines set forth by the Scientific Community. I did not make these up. If your experiment does not conform to the rules, it is invalid.

So, as of right no, I see no proof that this does or does not work. All I have to go on is observation experiences of others, and the majority of those say it does work. Does that mean it does indeed work? No. I now also have my own personal experience, as I applied this hack. I am finding that my battery is lasting longer than it did prior to the hack. Does that mean it does indeed work? No. For all I know, an app I installed or uninstalled could be the cause of my longer battery life. I am not an expert on batteries. All it means is that any claim being made are inconclusive and invalid.

I would love to do the experiment, if I was the one making claims either for or against it. I merely pointed out that proof has not been provided to back-up the claims being stated.

If proper proof has been provided, as I already asked, please point me to it!

What a thread...

Thanks for the instructions. It bothered me to no end to see those faux services represented in battery usage.

EDIT: The FP should be updated to rename the Mms.apk file too, which depends on telephony otherwise you get an error on reboot.

If you know anything about Linux and cpu idle states, the higher in the battery-use and the more % the "idle" process takes, the better.

Mine is basically 52% Display, and 9% Phone Idle (CM7). I would rather have it reversed.

Possibly more than removing .apks

I don't know what to take from this thread now. All I know is that, regardless of if the OP's instructions really work, there is a way to remove "Phone Idle" from using resources. Perhaps there is more to it than just removing those .apk files.

Looking at the above link the Notion Ink tablet had an update that removed cell services and increased battery life, THEREFORE IT IS POSSIBLE. Maybe someone would like to take a look at the update removing cell service and the one right before it to see what else may have changed.

My god, let this thread die.

There is NO radio hardware in the Nook Colour. Therefore it will DO NOTHING.

Please give some hard evidence with your hard claim. That, alone, has been the problem with this whole thread.

This has been disproved at least a half dozen times through actual testing instead of guessing and "common sense". The burden of proof is on you - show through scientific testing that it helps and we will all become True Believers.
