Debating about whether to install CM7, but there have been a few problems with it. I'm having a tough time finding the current state of the following issues:
1. Sleep of Death - Nook goes to sleep and doesn't wake up, forcing a reboot. There seems to be some debate over whether this is solved. One of the threads indicates that it's not a problem if you turn wifi off with the screen. Can anyone confirm?
2. Battery drain - Battery drains at 2%-3% per hour in sleep mode. I believe this is resolved. Can anyone confirm?
3. Premature Battery Death - Battery dies at various points over 0%. There seem to be various utilities for resetting battery stats, etc., but I can't figure out whether or not this is resolved.
4. Screen stays on when plugged in - Forced to hit the screen off button when plugging in the Nook. I've seen recent complaints about this one, so I'm assuming it's not resolved.
I did go through the threads and am confused about whether these issues still exist, so I figured I would try the Q&A section. If someone with CM7 wouldn't mind jumping in, that would be great. Thanks!
1. Maybe, I'm a lucky one but I haven't had problem with SoD regardless wifi on or off. I've been using nb100 and up, and now at 138
2. Using 138, i got 2-3% drop overnight, about 8 or 10 hours. With 120, zero dropped
3. Not experienced yet since I never let it down to sub-5
4. Mine seems act the opposite way: screen off, plug in to charge, screen automatically on, have to press power button to put screen off again.
1. I haven't seen this in recent nightlies.
2. Fixed; NC now deep sleeps when unplugged, even with WiFi on.
3. Fixed as far as I know.
4. Mine acts like yours and votinh's both; these are not mutually exclusive. If you plug in while on, the screen eventually dims instead of going off. If you plug in while off, the device turns on, sometimes just the backlight. I'd call this one minor, especially in relation to the other issues.

1) I get SOD about once a day regardless of how I have it set up. It does happen less with wifi on sleep only but at work I need to push data, so my wifi is on all the time and...it's an issue, not terrible but annoying none the less.
2) Battery drain, I get about 36 hours if I use it lightly, but I tend to charge it nightly because I can't take a chance of heavy use at work and loosing it.
3) PDB, never had this problem.
4) The screen turns off by just hitting the screen off button. This isn't a big a deal actually, since you gotta plug the thing in, another button isn't a big deal. I have katecca screen lock and off in my bar at the bottom, so it's easy to turn off. I also have the nook power off widget but I haven't used it much.
That's great. Thanks a lot for the responses. Really helpful.
I have only had it CM7 on my nook for one day, so im not sure about the battery issue. But i know i put it down around 10pm last night with less then half a battery and i got home from work around 3pm and it had about 25% batt left.
Besides that sometimes when i plug it in it stays lit up. but thats a "meh who cares" to me at least.
Running 7.1.0 RC1 with Dal's OC, On Demand, with lowered Voltage on the steps
1) I've only had one SOD ever (knock on wood), it seems to be mostly cleared up
2) Battery drain has not been a problem for me. On .29 it was more only 1%/hr for battery drain.
3) I haven't experienced early battery death at all
4) It isn't a big deal, especially if you charge with the provided outlet adapter for quick charge. Don't see this preventing you from installing CM7.
If these stats are correct from ASI (I'm hoping they are, they sound right), I'm at 76% after 3 days, 19 hours uptime, and 7 hours of it without sleep.
I say go for it. Even if it is off SD (mines on emmc) it is still a much better experience than stock/rooted. I doubt anything will make me change from CM7, unless ICS becomes a viable option in the future.
Just a follow up on this. I installed CM7 and have not had a Sleep of Death, have normal battery drain comparable to stock rooted, and have not had premature battery death. The screen does come on when I plug the Nook in, but like everyone mentioned, I just turn it off and it's no big deal.
So far, my wifi actually reconnects more reliably than on stock rooted 1.1. I'm overclocked to 1200 Mhz, with no voltage or other adjustments.
Following up again - I get a SOD or a reboot about every five times I turn off the screen in CM7. I tried to use Tasker to turn wifi off with the screen, which has solved the problem for some people but this made no difference at all. I was running a nightly from late July and updated to another from late August (173?) but the problem hasn't gone away. I may try Stock 1.2 rooted.

I had no SODs from almost a week with n165; I upgraded to n171, got an SOD first time I put it down for a while, so I reflashed n165 and I'm sticking with it until I hear of something I need.
WiFi always on.
As always, YMMV.

Just a little update:
Since using nb169, I got a few SoD, did update again to nb173, still got hit occasionally.
I never have this kind of issue before but lately.
The changes I made
a. Played around with ADW Launcher setting (especially Desktop Animation)
b. Recently installed Simi Clock and updated some apps (such Nook app)
c. Recently having 8GB uSD card plugged in.
For some reason, I don't think a. and b. causing problem but c.
can you run cm7 with the 1.2 or 1.3 updates from b&n? im on a autonooter 1.1 and have been wanting to move up to something better especially if i can have flash finally.

CM7 is custom Gingerbread-based ROM, it has nothing to do with stock ROM and there is absolutely no relationship between the two (except they are both Android OS)

thanks for the response
One last (I think) follow up. I installed stock rooted 1.2 thinking it CM7 causing me problems over the last month. Turns out I had the same problem on CM7.
I read my Nook before I go to sleep, so it's often dark in the room. I turn the brightness WAY down. The problem ended up being the Adjbrightness "Lock brightness so other applications can't change" setting. It has something to do with screen dimming when turning off the screen. This setting being on was causing frequent reboots both on CM7 and stock rooted 1.2. I ended up going to ScreenFilter instead, and the problem has completely gone away at least so far.

I try to stay up to date with the latest nightlies.
1) This is not completely solved. It's rare now (I think it was issues with WiFi), but it has still happened to me recently.
2) Battery drain was fixed with kernels that support Deep Sleep correctly. Not any 7.0.x builds, only 7.1.x+ (RC1) and nightlies have fixed kernel. So this shouldn't be an issue (unless you have a rogue app that is keeping the CPU active, which would prevent Deep Sleep. The "CPU Spy" app will let you see if this is working correctly).
3) This is better, but still a problem. My Nook Color will just switch off at 4% battery now. It use to switch off when I was a lot higher. It's not supposed to do that. It's supposed to gracefully shutdown when low. I have several iOS and Apple devices, so I'm use to things shutting down correctly when low. My Nook Color always just randomly powers off.
4) This isn't a big deal. The screen comes on when charging, but you can turn it off if you want. It stays dim, and the Nook Color charges fine. Dalingrin (the kernel developer guy) said leaving the screen on was a fix to some nasty crash.
#3 is the biggest issue to me, as I've been in the middle of something when my Nook Color randomly powered off. Clearing battery stats, rebooting, etc - none of that makes it perfect.
#1 use to be the biggest problem, but it's very rare for me now.
#2 has been fixed, and #4 doesn't bother me.

I misspoke; n165 SOD's on me too, so I conclude that I dl'd 165 and didn't flash it; I reflashed n161 and have been stable since.
I keep WiFi on for email and podcast updates.
I've always got an 8G uSD card in.

Hello all, I just wanted to get some community feedback on an issue I am having with my hd2. First of all when charging my phone with winmo the battery only gets slightly warm, the same goes if the hd2 is charging while powered off.
Now the problem is while using Android. The battery seems to be heating up to 41 - 45 c. Also most of the heat being output comes from right under the 5 buttons. I have noticed that if I the reboot into winmo and the battery is less than 100% the indicator light will alternate green and orange every 3 seconds, but this only happens after rebooting from android. Now if I do a hard reset this fixes the problem.
Any thoughts as to what it might be? Possibly a radio issue?
Sounds like you are dual booting - something I have never done, but as there is more going on when you boot into Android and the phone has dual boot, I would imagine that its linked to that.The CPU will have much more to do and using power and charging at the same time is sure to push up the temps on the phone fast
Have you considered a nand Android rom? the Froro versions are very fast, stable and suitable for 24/7 use inmh of course.
I think that. the heat issue would then vanish
Has anybody experienced random shutdowns on their N4? It's happened twice now for me in the last few days. I'll go to turn on the screen and find that the phone is completely shut down and needs powered back up, without me having shut the phone down.
One strange thing associated with this is that it completely wipes my battery stats.
Please provide more information.
Stock? Unlocked? Rooted? Custom rom? Custome kernel? Undervolted?

Sorry, stock rooted. Both times happened when there was plenty of juice left in the battery, this morning when it happened I was still at 95%.

Are you sure it's actually shutting down?
The reason I ask is that there's an issue where the screen won't wake up, but the phone is still functional (can still hear notifications and feel vibrations etc.). It looks like it's shut down, but it actually isn't.
If so then I believe it's a known issue, even on the stock (unrooted) rom. It happens to me every now and then, and as far as I know it needs a hard reboot to fix (hold down the power button for 10 seconds).
Don't know what you mean by wiping your battery stats? A reboot would do that anyway, wouldn't it?

There's a video on youtube showing how this phone just shuts down after running a benchmark for long enough (that was about 10 minutes at normal room temperature..)
Could it be that your phone was doing something in the background, and because of the overheating issues that it has, it just shut down to prevent damage?

I wasn't doing anything significant right before hand. The last things I did were: checked Facebook, modified a Tasker profile, and swiped away a couple apps from the recent apps screen. Phone was cool to the touch. I was in the basement with no cell coverage (wifi connected), then moved upstairs and next time I tried to turn on the screen the phone was powered off.

No it was shut down, had to hold down the power button for 2 seconds to boot it, felt the boot vibration and saw the boot animation. This happened after being off charger for about 2 hours, but upon booting the battery screen showed on battery for 1 minute. Usually when I reboot the "on battery" time is preserved.

Is there a fix for the screen not waking? I'm still on 4.2(stock and rooted), does 4.2.1 fix it? I can't seem to update to 4.2.1, if it does fix it. But that's another issue...
Ya know I'm starting to think it may be my belt holster that's somehow shutting down the phone. This is the first day of my new holster and now the phone has shut itself down 3 times, each time I've noticed it after pulling it from the holster.

I only had N$ for 3 days.
Yesterday when I was taking a picture, camera app was running, while I was putting kids together phone screen went black. Only way to bring it back was to hold power button and it went through full boot up cycle, so I would say it did shut down on me.
Stock, no root, updated to the 4.2.1. Battery was between 50 and 75% and it did not wipe it's stats.

Oh man that's gotta suck. Worst moment possible. Mine has shut down as well several times.
I find that my phone likes to randomly reboot when using bluetooth. May be a coincidence or not. At times the widget toggle for bluetooth stops working too, so there's something going on with bluetooth. My bluetooth problems documented here:

Does anybody know a sequence of button pushes that will shut down the device? I know holding power for 10 seconds causes a reset, but is there a combination of button pushes that initiates shutdown?

If you hold just power button it should bring a popup with Power Off option, which is a standard for most Android phones.

I have the same issue recently. I've used nexus 4 for 1 month, this issue just occurred recently. it shutdown without any notice. I've drop my phone once, cracking its glass back, but it doesn't seem to relate to that issue. I guess maybe this is some software problem.
After I upgraded to Kitkatt i have noticed bluetooth appearing in the battery percentage. I have read from others about 5-10 percent maybe but my battery drain is ENORMOUS given the way battery was before kitkatt. I have done a full factory reset and wipe. It seemed to fix it and i was so happy. Now it s back and i have no clue why. I don t use location services. Battery saving button is always on and i keep it to minimum usage.
Ps: the screens were taken a few mins after i woke up. So there was no active usage on the phone during the drain because i was sleeping.
Ps2: Bluetooth has never been turned on. I do not use it.
Ps3: This happens in bursts of battery drain. 5% may be used while i wrote this post and some facebook use for 1 hour, and after a while in 1 hour of leaving it on the table i will lose 10% from Bluetooth.
Tldr but did you try hard reset the phone?
Also try rebooting the phone in safe mode by holding power of button and then when power off menu comes on, hold power of for 3-4 seconds to reboot in safe mode.
Let me know if any of these work.
Hmm its weird that you have such an enormous bluetooth drain in the first place, and in the second place that bluetooth isnt even enabled??? You could maybe post an logcat also with enabling/disabling logcat since maybe bluetooth got bugged in a weird way on your system. Please quote my post since else I may not notice your post and then I can't respond back.
I'm experiencing some occasional (every day) boot loops that almost always require a hard reset to get out of. Usually, after a hard reset, my phone will work fine for some period of time. Probably related, I'm experiencing much faster than normal battery drain. I'm used to a full day's worth of battery with this phone, but am experiencing barely enough to last my through a work shift (7am to 4pm). Also, weird spikes of battery loss after a boot loop + hard reset.
I am not sure what is causing this issue. Sometimes, setting my phone down on a table will begin the boot loops, leading me to believe that the battery could be loose or faulty.
As you can see, there is a gap when the phone is boot looping and then a huge loss of battery life. My phone is a T-Mobile USA model that is CF-rooted. I don't know a lot about root, but I'll answer any questions that may come up.
What could be causing this? Any ideas on how to fix it?
Update: My phone battery drains every faster now and cannot even boot to homescreen at all. I am having major problems and cannot use my phone for any function.
Any help at all would be appreciated. I don't want to just take a loss on this device.
I don't know for how long you've been using the phone, but maybe the main problem is from the battery, have you tried using another battery?
and do you get the boot loop problem when your phone is connected to the charger?
