My nook will not go to sleep. I am running cm7 off of SD card. In spare parts Running is 100%, Wifi Running is 100% and Wifi On is 80%. Under regular battery usage, Cell Standby is near 100%. Partial Wake - Gmail and Facebook around 3%.
I am going to try and see if WIFI Lock will help so that the wifi turns off when the screen is off, but if that doesn't does anyone have any other ideas?
yea that didn't help. the wifi still says its on 100%....
I am having the same issue, except that I am running on emmc and using phiremod 5.1.
I am going to work on it this evening, if I find anything, I will post it.
This is normal, as covered in the CM7 threads.
Hey guys,
I'm running the latest release from nadlabak, 04.10 one.
I experienced battery issues on some previous releases as well, however i don't know if it's this release or what, but the battery usage is draining very fast!
I am not really running anything, I have liveprofile auto memory manager, and handset sms. liveprofile doesnt even really run, i barely use it so it should be either in the background or not running.
i looked at the battery usage stats, it shows email is using about 40% of the battery draining.
my phone is VERY warm, feels like the cpu churning through something... i can run at 52vsel with 1000mhz vrate. fine and still my battery is about 40% after 2 hours.
I reset to factory clock speeds and it drains the same if not faster!
not sure what's going on but its driving me nuts, google maps also shows to be running in the background, however i never turn it on, i reboot my phone, leave it as is and it shows maps is using 10% battery usage roughly when i havent even initiated it to be running(unless it always has a service in the background?)
i had releases from march that ran better, about 8 hours of battery life. and i believe even a april release was working fine. but now this latest release especially seems to suck up the battery, i dont know if its the releases or if something else has changed...but its very annoying holding a very WARM phone and having the battery get sucked up in 3 hours.
Looking at spare parts, does it sleep at all?
40% usage from email is high so something is wrong there but I doubt it's CM7.
Also, what AMM settings are you using?
Hi there, I'm running the following:
vmheap 40mb
amm: 6, 13, 24, 40, 51, 63.
any suggestions?
where do i find out if it sleeps, im in spare parts.
In Spare Parts, the first item is Battery History.
Go there and it will show how long your battery has been running (%) since unplugged.
If you select the top drop down list, select Partial Wake Usage to see which apps might be keeping the phone awake.
Where did you get those AMM numbers from?
I'd suggest my Balanced 3 (6-8-26-28-30-32) for a nice mix of free memory without being overly aggressive on the background apps.
If you use any of my scripts, disable AMM from having superuser permissions.
I had gotten the stats from another popular thread on this forum.
ill try your stats as well.
vmheap still 40?
also i still notice email is the one that has a huge bar graph usage on the partial usage stat page. not sure why email is being kept awake..
should i factory reset?
have you wiped cache/dalvik? If not do that.
Sent from my Milestone
I had wiped the caches multiple times, tried a lot of things, everything accept a factory reset.
I did a factory reset for the hell of it, set the amm settings as requested vmheap to 40.
everything seems to be running smooth and fine at 1000mhz 54vsel
and the battery usage is at 90% while being unplugged for 7 hours, will monitor to see if the usage drops substantially later on in the night but so far i think things may be fixed.
Battery usage is nearly constant.
That's not good at all.
Something is keeping it away.
What does spare parts show now for partial wake apps?
The partial usage is like 5% now vs what was like 50%. and email isnt even probably 2%. handcent sms is taking up the 5% roughly.
its at 80% after being on battery for 8 hours 26 mins. and i have probably used it for about 30-45 mins worth of on screen time, rest idle.
Oh wait, I think I misunderstood.
You meant that you had 90% left and only 10% used up, right?
If that's the case, that's pretty amazing.
I have expirienced that if I haven't done full wipe(factory reset) my battery is drainin like a crazy. That's happing in all roms I have used. So my opinion is to apply any update or now rom on clean Milestone
how to delete apps in android
i have recently started using android on htc hd2.. i am bit annoyed with the fact that i could not unistall a few apps which i am never going to use. eg liveprofile..and it keeps starting automatically
so could anyone tell me how to remove such apps?
Hi all,
Just rooted by Nook Color with CM7 and I 2 fairly major problems. I searched threads but could not find anything specific to my specific problems.
First, last night, I turned off the Nook Color by holding down the button on the left and selected "Power Off". When I booted it (after a long wait, see below), it booted but the battery was very low and I checked the battery life settings using Spare Parts app and it said it had been Running 100% of the time since last unplugged. Its as if it didn't power off when I asked it to.
Second, my reboots are super slow....I get the "Read Forever" words when I hold down the left button but it takes several minutes before I have to press the bottom button to get the screen (no indication that its booting or anything).
Any help would be greatly appreciated.
Why are you shutting it down at all? Just let it sleep. Even with the current sleep issues, it will only use 1% or so of the battery that way... try it. I hardly ever power off my nook. As for the slow boot time, there are a lot of reasons...
1. Did you install the OC kernel and forget to wipe dalvik cache?
2. Which version of CM7 are you running? a nightly, or the 7.0 release?
I just did a test.
CM7 cm_encore_full-63
update-CM7-dalingrin-OC-emmc-040411 set at ONDEMAND 300-1100
At 2am battery was at 100%
Standby for 9.5 hrs and it consumed 16% battery.
Not looking good to leave in standby.
Do you leave wifi on? It could be syncing or trying to sync the whole time it is on standby.

If you powered off your NC, it would not be using battery.. Period. Running 100% of the time is normal right now on CM7, but again, it was not running while it was powered off.
Slow boot? Are you using an SD card? If so, get a new one that's faster.
Im sure we had posts like this before. But Im stuck and need help. I was on cm7 nightly 87 with oc kernel. 5/23 and all was well. The this Saturday after playing pvz before going to sleep I put my nook to sleep with approximately 40-50% on battery and in the AM it was dead. I tought maybe I was wrong with the battery charged it to 100% flashed to 93 updated the kernel to 5-23 and played around with nook a bit, battery recolabration app, screen reco etc... Went to sleep approximately 70-80% woke up in the AM 44% just now typing this on nook went from 44 to 39% battery use shows android os 49%
I do play with new apps and maybe installed something bad but I can't figure it out. Please help
that is called PMD premature battery death.. theres a thread about it in nook android dev forum and is an issue with the current cm7

Thanks have to research that. Why would this just start ? It was working very good before. Thank you very much for the very fast response.
The latest nightlies (91, 93, and 94A) have an experimental fix that seems to improve things.

Yes I installed the latest nightly and left the nook over night. I left it at approximately 11pm with around 75%-80% this morning at 7am it drop down to 57%.
What I dont understand is that I didnt have this issue for a about a week that I had the nook and had the 87 nightly on it. The battery was amazing. It just kind of happen. I will start posting in the PMD thread this is very strange. Just seems that around 30% of battery disappears if nook is a sleep for a while.
No Drain - No Pain
I'm running version 88 and have virtually no drain whatsoever. I use an app killer and shut off the wifi before shutting down each night but can have less than 1-2% drop by morning. I can go a week without recharging.
Log battery stats
CurrentWidget, available in the market, is capable to log battery voltage, percent, current, and running applications list, to a file. It is also a home screen widget. Select widget type=clear text. Edit widget and change presentation to 2 column style. With these two changes all information is shown clearly. Touch displayed data value on home screen widget to cycle display between current, percentage, or voltage. Its useful and well done.

Wow thanks have to try this. Also will try shutting off the wifi before sleep. The issues is that I had no problems prior to Saturday, it was working flawless I would get no battery drain I would go to sleep with WiFi on no killing apps and get approximately same battery as when I went to sleep it was great. I dont get what happened.
Also like I said before in about tablet > battery use the "Android OS" now shows 41% when the battery gets drained. So some thing happens. I guess I can wipe /system /data and start over. I flashed the latest nightly this morning while the battery was on 55% (this is drain over night, as before sleep it was 77%). Lets see how it goes. And I was so happy how this thing performed !!!!!!
It was when you flash from n87 to n93 is the reason your battery is showing such different charges. the reason your are battery is draining so fast is because your nook is not deep sleeping. you can check to see if your cpu is deep sleeping or not with a free app named "cpu spy" Im also suffering from SOD and no DS.
There are 3 battery issues right now with the nook.
1) PBD, you can read about it here:

I was still on 87 when the issue first occurred. Now I understand everything you posted and will be more then happy to fill it out and etc.. what I dont understand is how come this worked before with out any issues, with no modifications

Also I never got Sleep of Death, I just got home and I`m about down to 21% from this morning 57% which is approximately 10 hours, there was some use today. I installed the cpuspy and current widget.
Cpu spy does show deep sleep 20%. I just put it on the charger and will take it of today. I did put all levers down in Nook Tweaks.
Lets see what happens. Now will report in the AM.
Today I had battery issues as well.
When I look at the battery usage, it showed
Phone Idle used 29%
Display 28%
Cell Standby 22%
Data enabled was turned on in Mobile network Settings. I turned that off and will check again. What would be using that if there is no hardware?
I had those turned off as soon as I installed CM7 few weeks ago
I've heard it explained thusly:
Phone idle = device idle
Cell standby = radio standby
Disabling those functions does nothing to increase battery life, as reported by kernel devs, though many users report otherwise anecdotally.

Had you by any chance just rebooted the NC before looking at those stats? The only time I've seen stats that high for those processes is right after powering the NC on. At that point, you're only seeing usage statistics for the last thirty seconds, and like any statistic, the smaller the sample size, the less meaningful the data.
I was in a reboot cycle where the unit would not power on without being on the charger.
I just checked again after installing build 95 and at the top of the screen it says 15 hours 50 minutes on battery. The percentages are still the same as before.
Ok here is my report from this AM. Took it of the charger last night at around 10:45pm with 100%, rebooted in to recovery to clear battery stats, rebooted to CM7 went to wireless enabled the wifi, deleted 1 wifi network (more on that below), made sure it was connected to my home network. Pretty much it. Battery showed 99%. Woke up just now 7am, battery shows 98%. Great.
So here are my thoughts and I think I have to experiment a bit more before conclusions.
1. Nook Tweaks with DAC boost could be causing an issue, maybe a better idea to do on demand rather then set on boot (still have to experiment.)
2. (this is most likely one) I live in Long Island and we have free wifi from Optimum (cablevision) from my house there is a week signal for that SSID and some times Nook did get on it instead of the home SSID. I suspect that it was jumping between SSID and thus draining the battery, this is why I deleted that network before going to sleep.
3. N95 fixed everything that was wrong.
4. I changed wifi to sleep after screen is off, that could of helped as well.
More testing will be done in coming days.
I do have a question regarding the OC kernel and governance. I do remember having 4 options, but now I just have to 2, performance and conservative. First question which one to use ? Second question where are the 4 governance ? Why arent they showing up ?
Thank you guys.
Dalingrin found that the smart-ass and interactive governor were causing issues (don't recall what, exactly) and pulled them out. Conservative is recommended.

Got it. Thanks.
I'm on n98 with the 5/23 OC kernel (I believe). I always make sure minimal apps are running, I only have the wifi/sound/bluetooth toggle widgets. Screen brightness kept to minimum needed for visibility.
I charged up to 100% at about 6pm. Put it right to sleep (no wifi or anything running) and within 10 minutes it was down to 98%. I read for about 30 minutes using Aldiko before I went to sleep and for 20 minutes on the train to work. I pulled out the Nook on my lunch break to read some more and it was down to 59%, and that is just sleeping and reading (on low brightness) for about an hour.
I always have ample opportunity to charge wherever I am, but I'm just paranoid about battery life not lasting at all even when I'm barely using the thing.
I was set to OC @ 1100Mhz on Conservative but I knocked it down to 800. I don't know if that makes a difference.
Should I go back to an older version? Go to stock ROM? I'm really only going to use the Nook to read and watch Netflix on the train, or browse some websites on my lunch break. Nothing too heavy.
My HD+ running Cm10.1 (verygreen emmc) uses 10-15% battery sleeping through a day. Battery status showing "keep awake" under "Android OS" being the largest consumer. I noticed that notifications are very alive during sleep as it beeps periodically. Is there a setting that will allow me to put everything on hold (deeper sleep?) after a certain time into superficial sleep (screen off)?
Thanks

I don't think 10-15% a day is very much... Much better than any of my android phones.. Tablet will probably last about nine days if you don't touch it. Here are my stats.. I've barely been using it.
10-15% on the Nook HD+ is actually quite a bit.
I leave wifi off and might lose 1% over 24 hours, sometimes no loss at all.
something is draining it.
I think this should fare better than phones because (1) there is no constant-on cellular radio, and (2) it has a much larger battery. When screen is off the power consumption should be comparable with a phone with similar cpu/mem minus the radio. so more juice and less consumption = longer standby.
In any case, I am looking for settings/config that will, e.g. turn wifi off after screen is off, and perhaps freeze the running apps. I suppose such controls exist, but I could not find anything in the "settings" ...
On a related note, How did many apps mange to run themselves without my consent? I used ES task manager to disabled many programs from the start-up list, but some apps (some not even in the list to begin with) would be appearing in running apps list from time to time even though I am sure I did not start them after a reboot. Facebook and Youtube seem always running; some games also do that. I would kill them, and a while later they would be running again. Is it possible to really prevent apps from starting by themselves?
Sean
10-15% is horrible. I don't know what phones you have but none of mine are near that bad. As for a tablet that is doubly bad and on this one in particular since it has no cell or gps radio. If you check my SIG you will see I've personally owned several tablets and I can assure you not even one of them nor the six or seven more owned by other family members I play with have lost so much during sleep cycle. At 15 percent you would only get 6 and a half stand by days lmao. No this is a matter of inefficient kernel controls.
agreed 10-15% is completely out of character for the Nook HD+ .more like an app sucking the power or that particular build.
The Nook HD+ is one of the most efficient tabs in existence for deep sleep mode.
which build are you running?

Cm10.1 verygreen emmc 0712 (was on 0719 but had spontaneous reboot problem so flashed back).
We have another HD+ running stock, and that one has much better standby time. I've installed the same launcher and pretty much the same apps (both are on the same google account).
I'm not with the HD+ now, but basically, "Android OS" and "Google Service" each uses 30% of the power, while the rest are much smaller. So I could not pinpoint an app as culprit.
I do have location service enabled; maybe GPS as well (would that make a difference?). Email is set to check every hour.
How do I make wifi off automatically off while sleeping? (Wifi is not even a big consumer in the list though.)
