So I flashed the new Fresh ROM and it is taking FOREVER to charge. I finally got it up to 100% and less than 7 hours, it was completely dead.
Any ideas?
Me too! Killed my battery in 7 hours while charging overnight!
Have you looked at what's using the battery?
I know in some of the other 2.1 roms, facebook is constantly syncing which kills the battery.
You can use logcat in sdk to see what the phone is doing while it's idle.
Also, service can also change the drain on your battery. I know at work (inside a 3 story brick building) I get horrible service and my phone is dead by noon if it's not plugged in. At home, it can go all day and then some.
Same issues here. Takes forever to charge and dies quickly. I haven't flashed the new radio yet....could this be this issue?
I've been using it since he released it and battery life is more than excellent. I can go a whole day then some
Go under settings, about phone, battery. What is your uptime and awake time?
Then tap on battery use. What has the highest percentage of use time on your battery?
Also check out 'cell standby'. Tap it.. Time Without Signal should be very low, or missing.
up time 8:57
awake time : 2:42
highest use is close between cell stanby48% and phone idle 47%
time without signal : 0%
BTW my battery was at 38% with little use(a few text msgs and fb mobile a couple of times)
TWS is fine then. Do you have the sync icon constantly running?
And what is your PRL/PRI (sorry if you posted that already).
PRI - flipz_01
PRL - 60663
What about the sync icon?
sorry....no sync icon
Weird. Any mods/themes/etc?
What I would do at this point is wipe everything (including ext), and reflash, then see if you still have the problems. I haven't had those issues, so I can't give you anything else to look at.
Perhaps someone else can, but that's all I can think of.
You could try the new radio. Some have said they get much better battery life with it (which is likely caused by the radio not having to search for signal as often...but since your TWS is 0% I'd be surprised if that's it). Try that, then nuke and pave would be my suggestion.
Last night was the first night that I had my alarm set. Could this have anything to do with the drain?
I had a weird issue with the battery. I don't know what exactly caused it and I could not pinpoint it with "Battery Use" nor "Spare Parts." My phone was staying constantly awake though, no matter what.
I eventually just partitioned the SD card, with no ext partitions (no apps2sd), flashed fresh again, and now it's all working great. I am installing my apps very slowly and monitoring them to see which one may have been causing the problem. So far no problems though.

I was getting decent battery life when I flashed 2.0d originally so this might not help you but after I flashed the newest radio my battery life got way better. I can listen to slacker radio for 4 hours while studying and use the phone intermittently throughout the day and get about 12 hours out of the battery life.
anybody who has crappy battery life check if your phone is on GSM auto PRL?

I'm running Fresh Rom and my battery is great. I haven't charged my phone since 6:30am this morning(it's 8:30pm here now) and it's at 60%. I'm using the new radio too.
scratch what I said yesterday, lol... my phone randomly rebooted overnight and now I can't get it to stop being 100% awake...
EDIT: Tried rebooting, tried "power cycling" phone, did the CDMA (Auto PRL) fix just in case, didn't install any new apps, battery use shows TWS at 0%, Cell Standby Time on = My total uptime.
Spare Parts Battery History shows my phone as 100% running, no sleep time.
Spare parts partial wake usage just shows Android System..
Battery is draining like crazy..

That shouldnt be an issue any more. Flipz fixed it in 2.0d.
Change your screen brightness to auto. When I first flashed it was at the highest setting and killing my battery. A lot better now...
Hi,
I have flashed my N1 with CM6.1.1 around 2 weeks ago. I'm really satisfied with this ROM.
However, I have noticed my Wi-Fi has gone a little bit weird after flashing CM. Regardless of the Wi-Fi sleep policy setting, my N1 won't turn off the Wi-Fi after it's locked. When I unlock my N1, I can watch the wi-fi icon disappear and then re-appear after a few seconds.
Now I have to manually turn off the Wi-Fi before locking my N1 to conserve the battery. Does anyone know how to get rid of this bug?
Thanks.
i will give you one tip which is its better to leave wifi ON when your phone goes to sleep because it's much better for battery life. if you let wifi turn off during sleep, the phone switches to 3g data which drains far more battery than leaving it on wifi.
now about the disconnect issue, i'm not quite sure what you're seeing. i have a problem with cyanogen 6 where my wifi disconnects for about 3 seconds, and this happens about every 10 minutes or so. its very annoying. but when my phone goes to sleep, i wake it up and still see wifi connected. so no issues there for me.
Wildmonk has some kernel just to address the WiFi issues.
I suggest WM kernel with CM ROM anyway
The problem occurs randomly. Sometimes my phone "knows" it should turn the wi-fi off when it's locked. But most of the time it doesn't...
I think I will live with it.
Anyway. Thanks for the reply.
My WiFi still disconnects every few minutes, then re connects again. It drives me nuts. Cyanogen 6.0
to momomok,
I think you have misunderstood the word "sleep" for Wifi, here sleep means when you are not using your phone the Wifi will turn off temporarily instead of infinitely. It's more like a nap. As you unlock the phone, Wifi will get awake. That's why you will see it re-appear after a few seconds.
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.
Hey folks,
I was running CM 7.1 RC1 with no problems other than the occasional Sleep of Death. But I recently updated to 7.1 and now my Nook dies in one day from about 50% battery without any use, (this has happened twice)!
I'm recharging it now so I can't check my settings but maybe I need to reset my Wi-Fi sleep policy? I wiped Dalvik Cache when I did the update but nothing else. Anyone have any ideas?
Check the battery usage stats and see whats draining your battery.
edit: settings>about tablet>battery use
you can also check spare parts.

Just checked battery usage and Wi-Fi is 85%.
Looks like I needed to redo my Juice Defender set up.
I always run my Nook with wifi off until I need it.

Same. With the notification bar Widgets it is easy to do.

If you are running a wifi widget, I suspect it will cause additional battery drain. I used to have WiFiWIdget (2K-Group) running and I felt that it caused excessive drain. I have since removed it since I ran 122N and 7.1 and have not had excessive drain nor SOD.
Juice Defender seems to be acting a little funky so I went ahead and changed the Wi-Fi policy in Spare Parts. Seems to be working fine now.
In the settings menu for WiFi, I just choose to either have wifi turn off when the screen goes off or leave it on while plugged in. I've never had a problem with waking up the Nook and it automatically reconnecting to my WiFi.
Hey guys --
I did a search and while there is much discussion of deep sleep problems, there is no clear way I could easily find to identify the cause.
I have CM7.20, the MiRaGe latest build on my NC, with the settings listed in my thread (see the sig). Recently I noticed that it is not entering into deep sleep, indicated by losing ~20% battery while it is asleep overnight in about 8 hrs. Battery results tell me it's "WiFi" taking like 30% of the battery, which seems quite odd, since I had it set to turn off WiFi while the screen off unless connected to the charger.
Any clues on how to identify the problem with deep sleep?
As for usage, I am using my NC 99% of the time with the following apps:
Moon+ Reader (probably 70% of time)
YouVersion Bible app (most of the rest of the time)
Dolphin Browser HD (maybe 2% of the time)
Enhanced Email and MailDroid - very occasionally but they are checking mail on 15 min intervals when wifi is on.
I have a ton of other apps installed but I almost never use them except for these.
Any help on how to determine what is causing the NC to not go into deep sleep will be immensely helpful. I have a 2-week Euro business trip coming up next month and I would really like to solve this before then.
Thanks!
Better Battery Stats might help. Try turning off sync before bed and see if you still lose 20%. If so, it's definitely some app that's the culprit. Grab something that will tell you what program is using data and how much/how often and you should be able to isolate it pretty quick.

OK, but it should be turning off wifi, and therefore sync for ALL apps, when it is asleep. Can an app override this setting? That's my guess, is some app is doing this. How can I ID that?

Like envygreen said use that app to track wakelocks. Even if wifi is off, some app may be applying a wakelock to try to sync.

Alright, I'm on it
So last night I finished charging it and read for a couple of minutes, then put it to sleep to see how it went overnight.
My Wi-Fi sleep policy is set to turn off wifi when the display is off.
When I got up this morning I checked it and it had lost over 10% battery over night, and I checked BetterBatteryStats and I think it is going into deep sleep but maybe not shutting off wifi.
I have attached the screenshots from BetterBatteryStats, and I think I need help interpreting them and finding the cause.
ok, so here I am replying to my own thread... If I am reading this right it seems to be looking like my wifi is on the entire time, not only when the screen is on. Is this the right way to read this? In this case, it looks like "Wi-Fi sleep policy" being set to "When screen turns off" is not actually working... right?

It sure looks that way to me too. It says wifi on 8 hours. Did you try toggling the setting a few times? Also you are on Mirage and he may have done something in his tinkering that messed that setting up.

yeah I did toggle the setting on and off, and in fact before I had it set to "On during sleep if plugged" for a long time, recently changed it, thinking maybe this was the cause.
But it does appear that maybe this is what is killing the battery. There doesn't appear to be any network activity when the screen is off, just looks like the wifi radio is powered up.
Any advice?

Hmm. that seems like an extreme step, but maybe ... wonder how much of the snappiness I will lose.
EDIT: OK I switched to CM7.2 stable. Nice I didn't seem to lose any settings. Let's see how it goes. Thanks for the advice, I'll report back here if it still does the same thing.
Also uninstalled beautiful widgets... figured maybe that could be causing an issue.
Oh, and I probably had a SOD kernel patch applied... perhaps that was the problem too
guess I should change only one variable at a time for a good test, but in reality I just want to get it fixed and not really diagnose it.
I was having a similar problem...what I did was run the V6 supercharger script, granted i am running CM9 atm but it took care of any problems I had with battery life and wifi signal.
Question: does having WiFi on keep the phone from going into deep sleep at all?
I have found that my phone is not going into deep sleep. I checked what is holding wake locks, and the time with wake locks is way less than the time the phone has the screen off, so it appears it is not deep sleeping, even though there are not wake locks.
I have an extended battery, so I get good battery life, but always interested in improving it. But I also have this thought that if I have to turn everything off, and only synch when I turn the screen on, that is not ideal either.

Get CpuSpy free on play store. It will tell you exactly how much deep sleep you are getting.
Having wifi on all the time should not prevent deep sleep. Only when things use it does it come out of deep sleep.

I have CPUSpy Free, and that is how I know I am not getting deep sleep. My challenge now is to identify why.
OK, so it seems that CM7.20 stable definitely fixes things. I didn't flash the SOD fix, so maybe the SOD fix was preventing deep sleep before, or maybe something else in the kang build was preventing deep sleep with wifi on when the screen is on.
However the better battery stats still seems to say my wifi is never actually going off. I am not sure I am interpreting the results correctly. It looks like the wifi is on all the time even though it's set to turn off when the screen is off. But I can let the NC sit on my night stand overnight and lose only a couple of % where it was like 10+% before. I still think my problem was due to some app that updated and not the ROM because the problem started weeks after I last updated the ROM.
