Current problems with CM7

[511pf]

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)

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.
