yup, it is whitelisted, i know, its weird...i used supernooter, and then the autoscript to install most of this "rom" im running, so if that has anything to do with it, i dont know...i hope youre right, id like to get it resolved

its funny no one else has weighed in on this to say i'm nuts or whatever
[Nook Color Android Development] RoboRay:

Root Explorer works fine for me and I haven't used adb or terminal emulator to mount the system in r/w.
[Nook Color Android Development] tnpapadakos:
see, it was that .001 i was talking about, you never know...

because for the moment i am wrong, and happy...because i just rebooted it and its f%$#@ng working now

that was a fun exchange, something to do on a day off...
[Nook Color Android Development] hvuong2:
Thanks...

Thanks... Worked like a charm! Now, I have to play with the NC to see in "real time" how much it has improved my battery life...
[Nook Color Android Development] RoboRay:

Glad it's working for you now. :D

I use SU File browser but had to use terminal to install busybox first before it was able to mount /system as r/w.

Iirc, the command i issued from the busybox directory in /system/xbin was. ./busybox --install -s /system/xbin

Of course this was after manually mounting as r/w first.

I did it all from my Nookie...
[Nook Color Android Development] fearphage:
I believe you can get the same effect by disabling the apps using the package manager and it won't require a restart as far as I know.

adb shell pm disable com.android.phone
adb shell pm disable com.android.providers.telephony

I got the package names from my Evo (I don't have a Nook) but you can find the package names if they don't match.

adb shell pm list packages -f

This has the benefit of leaving the files in place. If any of you want to try this instead, let me know if this is a complete and total fail. A disabled package is as good as having uninstalled or renamed it. It will immediately be removed from the app drawer although I can't confirm that the process will be killed at this moment. Phone owners typically use this to disable the bloatware that comes with some phones.

To reverse this, you just enable them:

adb shell pm enable com.android.phone
adb shell pm enable com.android.providers.telephony
[Nook Color Android Development] cal3thousand:
That should work. To think about it, you could use Titanium Backup to freeze them too.

I renamed the two phone-related files with root explorer as per the instructions, but even after several hard reboots, "phone idle" is still eating up a good chunk of my battery. Any ideas?
[Nook Color Android Development] xboxexpert:
Just move them somewhere in stead of renaming them
[Nook Color Android Development] RoboRay:
"Phone Idle" means your Android device isn't doing anything. That's like complaining about how much gas your "Car Idle" function consumes while sitting at a red traffic light. Your options are: 1) Turn it off, or 2) let it idle.
[Nook Color Android Development] CBJamo:
What program lets you see the battery specifics (the first pic)? It looks like it's the stock settings page, but I can't find it.

Would using a plane mode widget that turns off cell usage work the same?

Root explorer works fine for r/w and rename if the APK files as I have done this rebooted,etc. and confirmed. ADB not needed.

You are correct but instead of rename you can just move it out into another dir.

[Nook Color Android Development] Kokanee483:

On second thought, why would you want to cripple your phone so it can't make phonecalls?
[Nook Color Android Development] xboxexpert:
Who needs to make phone calls when you can have super battery life?! :confused:
[Nook Color Android Development] CsanMan:
On my second thought, I guess I won't do it lol.
[Nook Color Android Development] doomstalk:
The Galaxy S has a cellular radio in it, so it's not recommended. This is only useful on devices that don't have cellular internet.
[Nook Color Android Development] graymulligan:
For those that are renaming the files, you need to rename the extension, not just the filename.

I change filenames by swapping the ".apk" to ".bak" and have never had an issue, and the nice thing is the original file is still there with its proper filename, so they're easy to keep straight.
[Nook Color Android Development] RoboRay:
Yes, simply renaming or adding on to the extension is the best way to do it, so that you don't have to remember where the file came from nor what it's original name was. I just append ".disabled" to the end of the names, so that "filename.apk" becomes "filename.apk.disabled".
[Nook Color Android Development] khaytsus:
So has anyone actually verified this does anything? My wife's NC is rooted and has about 6 apps on it.. Nothing fancy turning off wifi, no CPU governor program, phone apk's and such left as-is.. So she's more or less my "rooted control" Nook.

I installed Battery Snap on hers a few days ago to watch her battery usage, and turns out last night she was so busy she didn't touch it from 7pm until I looked just now at 5pm the next day. 22 hours. Zero battery usage. 94% at 7pm last night, 94% when I looked at 5pm.

My NC with a crapload of apps and stuff running, but otherwise idle since 10pm until 5pm, 5% loss. That's .26%/hr. I have renamed the phone etc, but I also have lots of stuff that could be doing little things on my NC, such as two battery monitors (Battery Snap and Battery Diviner), two weather apps, and no telling what's running in the background otherwise.

My opinion as of this time: Renaming the phone stuff doesn't really change battery usage. Or said another way, the stuff showing up in Spare Parts for the Phone does not actually affect battery life.
[Nook Color Android Development] Ptaaty:
I tend to agree. I don't notice anything majorly different other than the battery use being reported as cell standby is now reported as phone idle. Previously Phone idle didn't really show up.

I think this is all a red herring and an issue how it is reported more than the actual use. Usage has to be reported somewhere - when I used the Adobe sketch program it showed up as using most of the battery even thought the phone just sat there.

I am still in the camp that it doesn't hurt, but that the NC doesn't really use much power in standby regardless, as long as you don't have a run away process or something holding wifi on.
[Nook Color Android Development] HotShotAzn:
Yeah I'd have to agree as well. The app might be running (maybe) but its the radio that would kill the battery (if it existed). Since there isn't actually a radio, I'm not sure if this is doing anything.

I'll tell you guys tomorrow morning. I'm running System Panel on it over night and that will give me a good measure on what drain, if any, the phone processes have.
[Nook Color Android Development] HotShotAzn:
I did my battery life analysis on a freshly reimaged and rooted NC. Read it here:

[Nook Color Android Development] bjkaria:
Disabled this service yesterday (battery was at 98%). Since then reading time has been about 2.5-3 hours. Battery at 70%.

Based on usage last week (without disabling cell standby), battery would probably have been at about 55%.

Will continue to observe.
[Nook Color Android Development] French.:
My personal experience has been much better standby (when not using)...I lose almost virtually nothing. I can unplug at 7:00 a.m. and leave the device unused until 6:00 p.m. and it will still report 99% or 100%. Prior to the script I would lose roughly 1% - 2% per hour when idle.

In use I've noticed no difference at all...uses the same amount of battery while using it now as it did before.
[Nook Color Android Development] khaytsus:
As I've said in this thread, my wife's NC is rooted with some apps, no background stuff going on, but has the phone apk's unmodified, and hers loses 0%/hr, in fact 0% in 14 total hours last I looked.

This, plus other inputs, I'm pretty sure the phone stuff showing up in the wake lock and such is a non-issue.
[Nook Color Android Development] French.:
I'm glad your wife's rooted Nook does not lose any battery while idle (without script). I was not so lucky. My Nook did in fact lose battery while idle (before script). Not sure why your wife's does not and mine did, but since the script mine now does not lose battery while idle.
[Nook Color Android Development] HotShotAzn:
Read my thread I linked to in my post on this page. I proved running the script does not do anything as the phone processes isn't even running.

Let's not forget the Nook doesn't even have a radio...which is the reason the phone process sucks any power anyways.
[Nook Color Android Development] triggrhaapi:
I would be willing to bet that your perception is clouded by your belief, and is not necessarily indicative of fact. HotShotAzn has posted some clear observation, which jibes with the vestigial nature of the phone processes on the Nook.

Surely you can't believe that you have worse balance because you stopped feeling for the tail your ancestors had which humans are not born with, can you? Such is the nature of the phone app on the Nook.
[Nook Color Android Development] devis:
To whoever is interested, I can mount r/w directly from root explorer. Superuser and busybody installed.

[Nook Color Android Development] KryptoNyte39:
I dunno, cell standby sure uses a lot of battery when the NC sleeps all day.
[Nook Color Android Development] clottier:
Worked perfect with rootexplorer rw. Just renamed to old and reboot.
[Nook Color Android Development] French.:
Seriously?

Bottom line....MY Nook is experiencing better battery life since I renamed the files. I don't care whose analysis proves what or that my ancestors had tails (your analogy truly perplexes me) I am well aware of the placebo affect. My battery usage used to look similar to what kryptonyte posted. In my case however, I only notice the difference while in standby. Actual usage did not change at all.
[Nook Color Android Development] khaytsus:
No it does not use battery. Read the last few pages of the thread.
[Nook Color Android Development] jleecong:
So you are saying that "Battery Use" is not accurate and does not do what the name implies?
[Nook Color Android Development] HotShotAzn:
So on my Nook, which did not have any additional scripts ran, does not show cell standby or phone processes or anything like that when I check Battery Use.

On top of that, run any Task Killer and see if cell/phone is in use.

Or use spare parts and check which process are tasking the CPU.

You have to remember that Android (thus far) is not a tablet OS. It's meant as a phone OS. Therefore, you will have remnants of cell apps/programs embedded in the OS. However, that does not mean they are actually being used.
[Nook Color Android Development] HotShotAzn:
I wasn't going to comment but since I already posted once :)

In this pic, what was your total drain for the 13hrs and 47mins indicated in the picture? Let's say (for the sake of argument), that it was 5%. 65% of 5% is only 3.25 %. That's what your NC drained in 13hrs and 47mins due to the "cell" process.

Now I'm willing to bet your idle drain was more like 2%. That means your cell process drained 1.3% over 13hrs and 47mins, or .09% drain per hour.

Trust me, people would kill for that kind of drain on a cell phone that was idle over night.

Statistics are handy...if you know how to read them.
[Nook Color Android Development] triggrhaapi:
You are experiencing a placebo effect. The tail analogy was awkward, but nevertheless, the fact remains that the phone processes are vestigial and remain disused in the Nook Color.

HotShotAzn has observed that having or not having certain apps installed will affect the battery life in standby much more than the phone processes will.
[Nook Color Android Development] cybertimber2007:
French, would you please reproduce what the other person did on your nook, and see if you see better battery life?

Maybe you guys didn't have science classes when you went to school, but reproducability is a key to proving something. ONE person has tried it and saw no reduction in battery life. That's not conclusive.

French were you on nookie froyo or stock? I'm going to try reproducing as well (only if on nookie).
[Nook Color Android Development] khaytsus:
It's a false positive. In this case it's showing up but there is no difference. Period.

I have not messed with my wife's Nook Color phone apk's and hers loses 0% damn near forever... Once didn't drop a single percent in 14 hours of standby.
[Nook Color Android Development] ashlander:
same code from a mac?

i tried the above code on my mac, and had issues... I'm not very experienced with code or script, so maybe I did it wrong, but I'm wondering if maybe the script would be different for a mac?

(Also, I guess I'd like to clarify the process: I plugged my NC into my macbook via USB, opened terminal, and typed the first line and hit enter, enter following line, etc. --- What is the step-by-step process? Is it that simple or is there more to it?)

(I will get laughed at for my noobie questions, I'm sure...)
[Nook Color Android Development] KryptoNyte39:
I can't help but ask, how seriously can you folks really take that screenshot of my battery life?
[Nook Color Android Development] khaytsus:
What?

Anyway, let me restate it, even though it's in this thread several times. There is no real, actual battery usage difference if you remove the phone apk's or not.

Feel free to test yourself.. :rolleyes:
[Nook Color Android Development] KryptoNyte39:
Study the image, very close ... ah forget it.
[Nook Color Android Development] HotShotAzn:
I was really focused on the Cell Standby I didn't even notice what the rest said :)
[Nook Color Android Development] French.:
For whatever reason I stopped receiving notifications on this thread so didn't see the further posts.

I will actually take the time to put the files back to original names because I'm 100% certain prior to renaming them I would lose battery all day even when in standby. If I unplugged at 7:00 a.m. and left the Nook sitting in standby until I got home at 5:00 p.m. and turned it on, I consistently saw it reporting anwhere from 94 - 96%. However with the files renamed (or maybe "since" renaming the files)...I can do the same and when I turn it back on at the end of the day it reports 100%.

Obviously the conclusion most of you have probably reached is that I had something running in the background causing the (admittedly very slight) battery drain. I'm not saying I didn't...what I'm saying is that since I took the time to rename the files I no longer see any loss at all when in standby whereas prior to renaming them I did.

I guess I had darn good timing on when I decided to do the rename. Now I'm curious as to why I would have seen the drain before but not now.
[Nook Color Android Development] cal3thousand:
As you have alluded, the analysis really needs to be done ceteris paribus.

Which is most easily done on a blank and fresh rooted device.
[Nook Color Android Development] French.:
I renamed the files to original last night, charged overnight and then unplugged at 6:00 am. To my surprise I still had 99% battery when I checked it at 5:00.

I was not actively on a wifi network (when I thought I was experiencing battery drain I was). I did take the time to shut down all background apps after unplugging it, which I'm sure I didn't do before.

Tomorrow I am going to try to leave it on the wifi here at home to see if I notice any drain.

This is interesting to me as I'm certain I was seeing drain before the renaming of the files.

And Krypto...I, too, was focused on only the first line of data on your jpg.
[Nook Color Android Development] mckooter:
i wont claim to be any sort of expert in this, but this is what i understand,

when charging an android device it charges to 100%, lets it fall to about 95% and then charges it back, obviously you couldnt continue the same voltage/amps after you were at 100%, so rather than charging 99-100% all night long it lets it drop a bit. so when you take a device off the charger you are anywhere from 95-100% charged but it takes a while for it to recognize where its at (if you google it a bit you will see a bunch of people complaining about 95%+ charges).

So in the case of your testing its hard to tell. you could have pulled the device off at 96% and not realize it untill hours later. There is no question that removing active running processes will improve battery life (by virtue of reducing cpu load) but I think we are grossly inflating the help it provides.

again no expert, just my $0.01
[Nook Color Android Development] Seamonkey79:
My battery went from around 5 hours of good usage to over double that since doing this. Arguments for both sides make sense, my real-world shows that removing them had an effect in MY NC. Will it have an effect on everyone's? I doubt it, just the same as ad-hoc wireless works fine on mine but not on others and 1ghz quickie works great, while others can't get even 900 to work. My testing was done over the last week since rooting, I reset back to raw stock and re-rooted just to verify. Without phone/telephony, MY NC gets considerably better life than it did with it.
[Nook Color Android Development] khaytsus:
I flat-out don't believe it. Restore 'em and test again.

And don't do it with another kernel, etc... You'll have to do it with the stock kernel.
[Nook Color Android Development] daman7676:
Just a note, I did see quite a few error logs being generated when I renamed phone.apk and telephonyprovider.apk. The errors where showing up in the /data/anr folder.
[Nook Color Android Development] khaytsus:
Until you rebooted or after? It causes a bit of a sh*tfit until it's rebooted.
[Nook Color Android Development] daman7676:
Hmm...I think it was before I rebooted. I undid the renaming as I'd rather it not generate errors anywhere else I haven't noticed.
[Nook Color Android Development] Seamonkey79:
Apologies... at some point in all my mucking about, this latest time through I did not do the rename/remove, so while I do have quite better battery life than I did just after rooting, it certainly isn't from the rename deal, next time I'll double check before posting :-]
[Nook Color Android Development] khaytsus:
I think you were primarily seeing the New Device Drain. ;) My Nook Color is getting 3 days of typical battery runtime now, where the first week it was about 1 day. :D

[Nook Color Android Development] VisedMonk:
Hi all. It appears that I'm a little late to the "party" here.

As for me, renaming the files made NO improvement in my battery life. I still have to charge my NC every 3rd day with what MY normal usage is (reading, some email facebook, and web, but I'm in love with my evo and I'd rather use that for my email and web). I'm not sayin' you people who noticed an improvement are lying, but I just don't believe that this is the miracle cure you all think it is.

I skimmed most of the thread, and didn't see any real, concrete, objective proof that battery life improved for those who deleted and/or renamed the apks allegedly draining the life force from your NCs. No real screenies, battery info, etc. Just a bunch of anecdotes that battery life improved. I'm thinking placebo effect. Perhaps this is the "new device battery drain" because the novelty wears off and we all stop fidgeting with things as much. I dunno. That happens with our mobile phones, so why would the NC be any different?

I think someone said this earlier, too, but "Phone idle" means "Nook color idle" because Android thinks your NC is a phone. That's the way it's programmed right now. So "Phone idle" means that your NC uses a little bit of juice when unplugged but on and in standby. Oh my dear lord, my electronic device used juice while unplugged!!!! Why is this such a *shock* to people?

Seriously, folks, who really cares if you drop 1% unplugged with no usage throughout a day or 0.5% with no usage throughout the day. So at the end of the day, even if "Phone idle" was 60% of your battery use, or whatever, but your battery only drained 1% over that time period, that's a very small number. How would you notice that anyways?

That's my $.02.
