When my phone is sitting idle (screen off) it will randomly decide to power itself off. Has anyone else noticed this? Any ideas on what could be causing it?

you mean randomly power itself ON, right?
if that is the case, it's normal, it just mean it woke up to connect to the internet, to get updates of news, emails, or whatever it was scheduled to pick up
nope. i mean it randomly turns itself off. this topic is being discussed over on the att captivate galaxy forum section.
interesting, so it's going from stanby mode, to complete OFF... nope never seen that happen to my i9000 model
yep totally powered off... completely sucks... looks like there are a bunch of ppl that have this issue with the captivate on att. $10 says its some lame piece of software that att puts on your phone that's causing the problem.
it's possible, i've read here a few users having crazy power issues (battery draining very fast) with their SGS i9000, but after wiping it out clean, to start anew, then the power problem is gone away.
so yes, a software could cause something weird like that.
Factory reset and so far so good
Hey guys,
I use a Galaxy S here in Hong Kong and I had the same random shut down issue constantly happen when my screen went off...
I tried everything, check temperature of cpu, etc. etc. and nothing worked, it just got worse and worse.
I even changed the battery to use the spare one that came with this. Still problematic.
Used SET CPU to limit the cpu to 400mhz, still problems.
Finally I did a factory reset and so far so good.
I only have the original system installed with the Remember the Milk app installed.
24 hours, no problems.
Installed AppBrain app.
Then I installed 3G WatchDog
12 hours, no problem.
Then I installed Paperdroid
12 hours, so far no problems at all.
If I run into an issue I'll post it here. But I think it definitely was a software issue.
Update - it randomly shut down on me
Alright guys, it shut down on my randomly today in the afternoon......
I dont know if it's the re-charging that screwed it up?
Because after my factory reset, last night was the first time i charged it....
Hmmm
This happened to me too - two days in a row until noon it would shut down two or three times - i uninstalled SetCpu and for now (24 hours) it hasn't happened again. I am not sure if it was the one responsible but it started happening after i installed two programs and i uninstalled them after it started happening. I uninstalled Visual Task Switcher first but on the next day it turned off again, then i unsinstalled SetCpu and it hasn't happened again - maybe some wrong profile settings but i didn't feel like experimenting
I had this issue once too in about 40 days.
I was reading an sms and then i turned into standby and put it in my pocket. Later, maybe 40 minutes i came home and my phone was completely off. I do not remember if i had to take out the battery before to get it on again.
I was wondering why it happened. Maybe it was caused by an app i had opened. Battery still was at 40%.
But since it only occured once in 40 days i doesn´t bother me.
Interesting you mention this as it just happened to me today for the first time. I took it out of my pocket and wtf? The phone was off. Very strange... Using the i9000 on the stock Eclair rom.
Should send back for warranty

software clash?
Well the phone suddenly switched off for me, but this time I turned off APPBRAIN and so far so good.
In fact, I came across an app called NoLED and since it kind of keeps ht phone on, while I have it on my desk, I'm able to be notified of stuff and so far with that, the phone hasnt' shut off.
I'm still experimenting with what works, but try turning off AppBrain and see if you still have the random shut off issue....
i use app brain all the time to keep my apps in sync
not the cause of the problem, that's for sure
my phone can last a whole day even with app brain running
OP, do you have MSN Talk installed on your phone? I have this same problem, seems to happen more when I am running MSN talk in a low signal area.
«try a new sim card. «Could be faulty. «i am on my 3rd phone and all of them had this same problem. «i bought a new sim card 4 days ago, and hasnt happened since. «but then again, this problem usually happens to me once every 3rd-5th day anyways, so i dont know if i am in the clear yet.
Me too, shutdown everyday
Hi guys
After upgrade OS to I9000ZSJG4, Phone random shutdown everyday.
Yep still shuts down
Tried keeping AppBrain off, still shuts down.
Used NoLED so the screen kind of stays on, still shuts off..
So far shut off on me after 40 hrs... this is really stupid.
I am this close to taking it back, but I genuinely think it's a software issue than a hardware issue...sigh
Anyone have any luck figuring this out?
Same problem no solution yet
Hi
I too have the same problem, haven't found any solution yet.
The temperature etc is all good, there is no pattern in shutdown issues.
I have tried factory reset and no new application, it still shut down while using in built browser.
I had the same thing happen to me while skiing in Whistler last weekend. It died twice. I attributed it to the cold. I normally use a 3000mah battery up there, but left it back the house that day. Afterwards while charging in the car and even charging it at home it died prematurely again. It was the eBay aftermarket variety 1500mah knock off. I have since changed back to the Samsung OEM battery. I haven't had an issue with it since. My assumption is that the knock offs in my case cannot handle the heat cycles of charging and then the cold as well as the original. Or they have a limited lifespan, well below OEM specs. I am now only using the 3000mah battery on the weekends to hedge my bet on the quality of manufacture, as it seems to be from the same factory as the 1500.
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.
Sent from my NookColor using XDA Premium App
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.

Hi All,
I have a rooted/custom ROMmed N7.
For some reason, most of the Custom Roms that I'm using just makes my N7 SOD. It usually happens if I have in activity for more than 2 hours but I also had some right after a few minutes. I've used different ROMs with different kernel and it was all the same. So it usually happens more than 5 times a day.
Now it came to me that my N7 could be defective since I can't tell if it was shutting down or SOD. I never had heat issues with so I don't think it is shutting down because of heat.
Is there a log somewhere that I could find that would say that my N7 had an SOD or a shutdown?
Thanks!

a sod is when tbe device is still alive nut the screen wont turn on, kind of like a coma. a last_kmsg will document a shutdown or reboot, but not a sod(since a sod doesnt reset).
Okay, so I've heard about the battery issues going around with the 6P's but I think I've got one that's a little different. My battery has typically been completely fine. It dies around the usual 0-1% and maybe some times 2-3%. However, whenever I use my camera app or Snapchat (which makes me believe it's related to camera apps specifically) my phone will die if the percentage is about 24% or less. I could be at 20% completely fine, but then go into Snapchat and it'll die a few seconds later. I plug it into the charger and turn it on, and it resumes with the same battery percentage. (If it dies at 20% it'll resume at 20%)
This happened on both marshmallow and on nougat. Has survived countless flashes. I've used custom Roms and have flashed stock over again. Not in attempts to fix the problem, just for fun.
Anyone have any ideas of what's going on or experience something similar?

Huh, you know what? I actually haven't. I'll give it a shot to see what they say. I was thinking I've tried everything shirt of replacing the battery (which I don't think would fix it). Can't believe I didn't think about calling. Thanks. Hopefully they've got a fix, but if not there are worse problems to have

Google support is great don't worry about it
Its a known issue, couple other threads on it
Does anyone have the same issue and knows what to do?
Since the update it
a) drains while not in use (depletes the battery jn 5 days without use approximately)
b) Rapidly goes from 90% to 60, suddenly drops to 30
c) Suddenly goes back uo to 60%
It seems as if the battery meter has gone absolutely crazy...
Should I contact Lenovo Support or is this a known bug that has a workaround or solution?
I can not confirm this.
But in my case I have done a hard reset. Maybe its also an option for you?
I don't have the erratic meter issue, but mine *does* drain the battery during sleep. The WiFi stays on, even though I have it set to "never".
I haven't noticed this problem. Various devices in my past have seen similar issues following an update before. A factory reset should resolve it, unless your battery has a physical problem.
First couple of days after the update I felt like my battery was draining faster, but that belief was corrected with use. Thankfully.
You can turn off WiFi scanning. This will shut down WiFi properly.
The one I have must be a freck I fully charge it and get 4 days of regular use........
Did you update to 170519? Maybe the problem is solved then.
