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.
The battery life on my NC is absolutely horrible. I average 3 hours unplugged, 1 hour if I'm using it. It doesn't seem to charge up all the way -- after plugging it in the light on the Nook cord is orange for about 10 minutes then goes green even though the screen still stays "Not enough power to turn on - Try again in 15 minutes".
I've tried using software like juicedefender and other battery mon apps that are supposed to be able to predict when you're going to lose your power -- but they appear to be useless. Often I'll get the "Your Battery is Getting Low" message at the very same time as the "Shutting Down" dialog appears -- almost like there was a very sudden dramatic drop in available power.
I am beginning to wonder if it's the result of faulty hardware.
Has anyone else experienced problems like these? Or should I restore back to stock and send it in for warranty?
That definitely sounds abnormal. I'd probably restore it back to factory and if it's still acting like that, you'll know it's not due to any modifications.
Yeah, I second that. Mine drains pretty quickly, I go from 100% to about 60% in a day with normal usage. I use Wifi Auto Toggle to turn Wifi off when the screen turns off. So far I have to recharge every other day or so. But what the OP has going on sounds pretty extreme.
What ROM are you using?
What programs have 'keep screen alive' do you run?
How bright is your screen?
Screen/wifi burn most of the power in this - so minimizing them helps battery life considerably.
I had one game (HexDefense) that prefers to run in maximum brightness and burned through the battery very quickly. Nook was the warmest I've ever seen it and the temperature on my battery monitor actually moved for the first time ever.
SO if you're getting 3 hours doing nothing, that's bad. If you're getting 3 hours running a really processor/graphic intensive game, that's good.
If you can get it back to stock and still have low battery life, consider talking to the manufacturers about it.

You really question this? Something is wrong with your NC, cable, or charger.

You might have some rogue apps running that overheat the cpu. Look in taskmanager which apps are using much power. Download cpu spy free from the market to see if the cpu comes in deep sleep or not.
Good luck
I also have it occasionally. POWER+HOME button to reset. One time need to remove battery. Actually I felt like phone is still open but screen cannot come back. Next time I will call my phone when it happens.
I've had this happen twice. Both times a battery pull fixed it. At first I thought the phone was going dead, completely black and the power button would do nothing, but the second time I hit the volume button several times and it started beeping, so even though it looked completely dead, it was still turned on. I don't know what the problem is, but probably something software.
Which ROM/kernel are you using?
Any special CPU profiles?
How's the temperature?

happened a few times too. So, last time when I found it "dead" I did some test.
1. used my bluetooth headset (MW600) tried to play music, surprisingly music started playing but screen cannot turn on by any keys.
2. I called myself using another phone, Caller can hear ring normally and the call NOT dropped to voice mail, however my Note doesn't ring at all, screen still cannot turn on by any keys.
So it doesn't look like it's auto switched off by overheating, seems like unable to completely wake up after deep sleep.
Phone using Stock Rom(rooted with CWM), with System Power Saving mode turned on. I suspecting it's related to the power saving mode.
I'm also stock 2.3.5 rooted, with CWM, but do not have system power saving turned on. I haven't noticed any heat, but haven't monitored temperatures.
Do you also have the stock kernel?
Are you using setCPU?
Try using cpuspy, from market.

Dead
I also had this case yesterday for the first time. I bought it the 30th november.
Did not want to wakeup, darkscreen. Only way to recover was to remove battery. I am on 2.3.6 french.
I do not use Setcpu.
Mine is unroot. In other words, stock ROM and kernel.
I think it is software problem. And I think it is either Samsung software or Android system. Someone need to run logcat though.
For your information.
When you sure it's sleep dead(not shutdown cause by no battery)
Disconnect any charger/USB connected. Press and hold the power switch for around 10-15 sec,
that will restart the phone, no need remove that inconvenient back cover for battery pull.

The first time it happened to me I tried holding the power button but it didn't work, so I did the battery pull. I haven't tried again since then.
Sudden Shutdown
Mine too i've experience it 3 times, this happen when im opening some applications sudden black screen and restarted cannot access back button, haven't tried the power button. It just restarted thats it!!! Im at stock kernel unrooted 2.3.6 so what do you think guys should i root or just wait for Ice Scream Sandwich upgrade?

See if you hold the button long enough for over 10 seconds, before I would release and think power button not work after 7-8 seconds.
I have experienced "sleep of death" many times on different firmware versions. I has never happened since I flashed KL3. I'm on AbyssNote 2.1 kernel.
update:
since I replaced the stock launcher & locker, no more sleep dead issues. I suspect the problem source is stock locker or some stock widgets. Also, battery last longer too.
now using: widget locker + awd launcher ex + multi-picture live wall paper.
For those wonder why phone can't wake up for some reason, a user at the green power app forum had got the solid evidence.
http://greenpower.pouzerate.com/ind...-s2-freeze--black-screen?limit=6&start=48#465
"And if then it looks like the touchwiz launcher has crashed and changed pid when restarting without telling the InputManagerService about it, so it can't wake up the screen for that reason."
So the culprit is the stock launcher. And this matched with my experience even after I uninstalled green power free, my phone still have "not waking up" problem . But since switched to use 3rd party lock and launcher for a month, the "not waking up" never happens again.
This happened to me for the first time yesterday, when I eventually got it restarted by removing the battery, it was at 88% so don't think it was overheating, otherwise it would be much lower. Also I had Go launcher Ex running so touch wiz unlikely to be the culprit. Maybe some widget, I have loads!

This actually fits well with my experience. Touchwiz crashes on me occasionally and just last night I was experiencing the sleep of death thing. This time I thought it might have been the battery, so plugged in the charger and that somehow woke the screen back up to show touchwiz in the process of starting up, caught red handed!
This has happened to me as well 3 times, and every time it has been related to using a highres picture on the stock locker. It would lag out on unlock, black screen of death, which i would have to batt pull to fix. Didn't realize i had to hold down the power button for 15 secs to achieve the same thing. Have since switched to a low res pic on lock screen and haven't experienced the issue since. Will try the alternative locker solution if it happens again.
I've been having this problem since around the time I first flashed Eclipse 2.2.2 and got on to the .906 update. When I leave my phone idle for about 30min or the screen is just off for prolonged periods of time, it will just freeze. I can't wake it up. Pressing the power button and long pressing the power button both do nothing. I've tried calling the phone but it doesn't answer. The only thing I can do is do a battery pull. It works perfectly fine when it's on, but it's kind of annoying to do a battery pull. This happens on Eclipses 2.2.2, Eclipse 3.0, and Maverick 4.0. Any suggestions?
EDIT: found out the freezing was caused by having 2 CPU apps. I had Voltage Control and SetCPU both installed at the same time so it was causing this. MODs feel free to close thread
Hello, hope you can help, i have a moto x (1053) the problems is that the batterry remains in 1% for 20 or 30 minutes before it shut down. I tried charge it to 100 and then left the phone turn off but the same situation passes, 1% of the batterry for 20 or 30 minutes before it shut down. Im running T-mobile 4.4.3,
Program for calibrate battery did not work either. Anyone can give another thing to try.
Maybe a battery Problem? . GSAM says the battery duration its about 18 hours with 3:45 of active display.
Hi, see here: http://forum.xda-developers.com/moto-x/moto-x-qa/battery-suddenly-drops-t2533071
If it's a new one, wait for 3-4 full charge/discharge cycles.
This is a known problem. I've gone through over 40 cycles and still get the same 1% issue. Currently no fix available until Motorola release some sort of an update.
I've just opened a new case with Motorola regarding this issue.
They told me to hold down the power button and the vol down button for over 2 minutes then starting in normal mode. She said that this method forces a hardware reset of the processor and terminates all running commands.

Guys....this is perfectly normal, and there is nothing wrong with it. I'm not understanding why you are even concerned!!!
Car manufacturers do the exact same thing. Your car shows "empty" long before you actually run out of gas. Why? They don't WANT you to run out of gas....
So why not warn you well ahead-of-time that you are about to lose your battery and shut down, possibly giving you time to find your charger and charge it up!
Why would anyone complain that their phone is taking too long to "die"? I don't get it. Also, this happens on my 10-month-old X too....and I sure do appreciate it (Thanks Motorola!!!), because it has prevented my phone from dying multiple times....
Besides: to the OP: you are getting 18+ hours battery life????? That's --EXCELLENT--!!!! Please don't worry about the 1% thing...
