[Captivate Q&A, Help & Troubleshooting] jswclw:
Mine shutdown again today. Upon restarting, it was at 88% battery, just like it is after 95% of all shutdowns. There is something magic about that percentage. If the phone is not busy with me actually doing something as it passes the 90% mark, it will shutdown.

I've about had it. Only because it is so predictable have I been willing to deal with it this long. AT&T service center says that it is a known problem and will be fixed with software soon. I wonder though.
[Captivate Q&A, Help & Troubleshooting] flintdragon:
My phone shutdown again today after about 3 weeks since battery replacement and factory reset. Taking it in to the service center hopefully for an exchange. Also have the random search button press and sound issue... grr...

I used a non-samsung nonoem battery. charged it all the way up. then fell asleep. Woke up it was OFF!!

I tried bt on and off,

wifi on and off

I have not put in in Airplane mode.. but that defeats it 100%

different batteries.

the captivate keep alive seems to work.. but then i dont want to use it cause it kills the top 15% ish of the battery and this thing dont live all that long in the first place!

i am on the phone right now getting a new one sent to me I hope.. I just dont want to go thu reinstalling EVERYTHING over, but thank got for Titatum backup..
[Captivate Q&A, Help & Troubleshooting] dbs179:
I got my first Captivate (1009) about two weeks ago. Right after leaving the store it shut down while in my pocket. I thought maybe I had not locked it and accidently powered it down. Over the next four of five days I had at least five more shut downs. I took it back and got a replacement.

The replacement (1010) was working fine for the first three days or so but it's shutting down now too. Not as frequent, but still I've had about three shut downs in a week. My wife got a Captivate the exact same day as I did and her's hasn't shut down yet. I'm going to return this phone one last time, if it shuts down again, I might have to go with an iPhone 4. I really don't want to, but I travel a lot and use my phone for an alarm. I can't have it randomly shutting off while I'm on travel and end up missing a flight.
[Captivate Q&A, Help & Troubleshooting] volusia7:
I thought I'd chime in here as well. Got my Captivate in Aug. 1007 version. Mine shuts down between 11pm and 5 am now with regularity, and occasionally during the day if I am outside. I do think this has to do with temp, as when I am outside and it's cold, I mean really cold, it will shut off. The way we heat our house, the coldest time is between 11pm and 5am. I have contacted AT&T warranty and they had me do all the normal stuff to test, even the master reset, which is a pain. I am waiting on a call back from them now to tell them it's still turning off. Hopefully I can get a new one shipped to me before I am on call next weekend. Although from what I am reading, keeping it on the charger will keep it from shutting down... again, if it's charging, doesn't that heat up the battery?
[Captivate Q&A, Help & Troubleshooting] dbs179:
Volusia,

I tend to agree with you. This morning it is especially cold here. I came into work and set my phone down on my filing cabinet that was cold. Next time I picked it up, it was off. The other times it has shut off have been vary similar. I'll try putting it in the fridge when I get home tonight. :)

Dave

Update: Ten minutes in the freezer and it didn't shut off. I then put it back on my filing cabinet and left it there for about 30 minutes. Come back to it now and it's shut off again, interesting.

Update 2: After reading a bit more, I decided to try to turn the Power Save Mode off. Since I shut it off I have not had a shut down. I've even tried throwing the phone back in the freezer and laying it in the exact same spot on my filing cabinet (I've read other places that it could be related to weak signal). It's back in the freezer again to try and duplicate the shut down. Hopefully the Power Save Mode trick works for me. As an FYI, since I started testing, I am not rooted, everything stock, the only thing set up on my phone is my google account for contacts and email and no apps other than the pre-loaded bloatware.
[Captivate Q&A, Help & Troubleshooting] Nimocone:
Update: To recap, my phone started shutting down about 1 month after my August purchase. I noted it happened when the charge was off the charger and between 100-80%. Below 80%, no problems. So I started using the "keep alive" program with success. On Dec. 3rd I received my Seidio extended battery. I have not had a shutdown since using it so far and "keep alive" has been off. I can see why AT&T wants to replace batteries first. After a week of use, I'm going to switch back to the stock battery and see what happens. I'm going to assume that it'll go back to shutting down again. If so, I'm going to see if AT&T will replace just the battery.
[Captivate Q&A, Help & Troubleshooting] rudous:
I wonder, couldn't be these shutdowns because of partitions failures?
[Captivate Q&A, Help & Troubleshooting] mobileseq:
Havent had these issues on mine yet and got it about almost a month ago, should I trade it for an iphone?
[Captivate Q&A, Help & Troubleshooting] gt50:
On my phone I think shutdowns are related to wifi. Last night I lost internet at home. I disabled wifi so that I could use my phone. This morning. I tried running setcpu at 100/1000 on performance mode. My phone did not go into a coma for about 3 hours. At work I noticed that wifi was not connecting. I re-enabled it. Phone was dead less than 5 minutes later.

I changed the wi-fi sleep policy from never to never when plugged in. I removed the setcpu widget, and set it to the default 100/1000 conservative and unchecked the box to change settings on boot. I then rebooted the phone to take setcpu out of the equation. The phone has spent the last 5 hours on my desk at work, and has not shutdown.

Testing will continue. I am using WPA2 at home and at work. I recently changed from WPA to WPA2 at home about a week ago. This may be why it is shutting down more at home than it used to.
[Captivate Q&A, Help & Troubleshooting] volusia7:
AT&T is sending me a replacement phone. Notice I didn't say NEW phone. They are sending a refurbished phone with NO battery, and NO back cover. If it's the battery causing the issue then I hope to reproduce it before sending my original phone back. My only hope is that the replacement phone has Froyo already on it! (not holding my breath)

From my experience, electronics usually don't just misbehave, they either work or not. But battery packs do change behavior over their lifespan. Especially depending on temperature. I may purchase a new battery to see if that might resolve my issue.
[Captivate Q&A, Help & Troubleshooting] argus1185:
I too have been have all these issues with random shutdowns. So far i've only gotten two shutdown. Both are when its unplugged. And both are around 56-66% battery life when it was idle and not doing anything. I haven't had this problem before. I bought the phone 3 weeks ago, rooted it to the latest Cognition build since day 1. So i really doubt its the ROM issue. Im in Houston, and it has only recently been getting cold, and that seems to be when it all started happening? I dont know.

I have a question tho, i bought this phone from Amazonwireless. Could i still return it because its rooted?
[Captivate Q&A, Help & Troubleshooting] dbs179:
Update 3: Stopped at the AT&T store last night. The sales guy replaced my SIM and had me take my SD card out to see if that fixed it. Neither of us thought it would. First thing this morning after I pulled it off the charger it shut down again. I'm returning this phone again. I wish Samsung would fix this issue.

[Captivate Q&A, Help & Troubleshooting] FutureSix:
Something worked for me.... I have my captivate since early september, always had random shutdowns.... I flash many ROMs available here.... and since I tried running the "new" JK3 roms, my phone is now perfect... Currently running Perception ROM and never ever had a single shut down...
[Captivate Q&A, Help & Troubleshooting] gt50:
My phone is great now. I made the wifi modification stated in my previous post and my phone has not shut down. I removed setcpu yesterday.

My phone does not like being connected to wifi while it is asleep for some reason. I am sure this is an OS issue, since I have never had a shutdown while my phone was awake with wifi running.
[Captivate Q&A, Help & Troubleshooting] argus1185:
Do you guys think that MAYBE its the Cognition ROM? Like any of you guys that got their phones replaced and reflashed Cognition to their phones had the same issues resurface?
[Captivate Q&A, Help & Troubleshooting] fugeelama:
On my old Cappy I flashed back to stock several times and it still happened running stock 2.1. Got a replacement from the AT&T store and it's been rock solid (both stock and on Cog2.3b6).
[Captivate Q&A, Help & Troubleshooting] jswclw:
Running perception beta 8. Just a day, but no shutdown so far. This is unusual since I followed the flash with a battery recalibrate which in the pay has always guaranteed a shutdown the following day.
[Captivate Q&A, Help & Troubleshooting] cmeyer3:
My random shut down isnt random any more, any time I use my phone in the cold( less than 30f) my phone shuts itself off right away.
[Captivate Q&A, Help & Troubleshooting] eatonjb:
so do we think this could be an environmental issue?
[Captivate Q&A, Help & Troubleshooting] argus1185:
Oh ok, that makes me feel a lot better knowing its not Cog. I'm getting a replacement from Amazon, just called for an RMA.
[Captivate Q&A, Help & Troubleshooting] koreancanuck:
Nope. I haven't had shutdowns in cognition. Ever since I flashed a custom ROM, I haven't had any random shutdowns (at least not from VC app..)
[Captivate Q&A, Help & Troubleshooting] argus1185:
Thats good..i was just wondering. Because i had flashed it to Cog since day one and it hadnt shut down at all. But then again i dont really remember leaving my phone off the charger overnight or idle for a long time, so maybe thats why i didnt see it. But then i wantd to run test on battery life and tgen i noticed tgis happening after like 2-3 weeks of having Cog on it...weird huh..

[Captivate Q&A, Help & Troubleshooting] CLShortFuse:
Okay, so I got my phone to stop powering off (kinda). It used to power off 90% of the time it went on idle standby, but never while charging. I would let it sit and try to power it on in 10 minutes, it would be off. Captivate Keep Alive didn't let it power off, so it was definitely a sleep issue on the phone.

Somebody sold it to me unlocked and rooted. (Coincidentally enough, that was done with my SuperOneClick software).

Stock Rom + Root + Unlock => Random power offs (as I received it)

Installed ClockworkMod => Random power offs

Flashed Cognition v2.3b7 OC/UV hoping a new kernel and overclock/undervolt would help => Random power offs

Flashed stock JI6 (and stock kernel) => Random power offs

Removed SIM card => Random power offs

Inserted SIM card => Random power offs

Did *2767*3855# code reset => NO POWERING OFF

Fully charged battery and disconnected charger => NO POWERING OFF

It's been like that for over an hour. I'm hoping it works.

Now what I noticed is that the sbl.bin is "corrupt" on this device (1010 device). I lost 3 button recovery and access to download mode. Maybe this is related? Regardless, I'm surprised it's not dead yet. If SBL is bad and it powers off, it's probably a hardware issue.

After 10 minutes:

Installed 3ButtonFix (new SBL BIN) => Random power offs

I'm not going to risk it. I'll swap it

Btw, according *#0228#

Voltage: 4130mV

Temp: 38.0C

ADC: 730

VF ADC: 589
[Captivate Q&A, Help & Troubleshooting] cmeyer3:
Not just a environmental issue, I still have the shut down after charging. My phone will shut down no matter what the the battery state is when I expose it to cold temps.
[Captivate Q&A, Help & Troubleshooting] Konner920:
This only happens when I attempt to Overclock. It works for a few minutes, then totally locks up, or kernel panics.
[Captivate Q&A, Help & Troubleshooting] gibson3659:
I think you may be on to something with *2767*3855#. I did it a couple of hours ago, and I haven't had a shutdown. I'll wait and see.
[Captivate Q&A, Help & Troubleshooting] argus1185:
With tat reset do u lose everything?
[Captivate Q&A, Help & Troubleshooting] Crusty_Demons:
My phone seems to shut down most often when exposed to cold temps when you pick it up it feels cool to the touch. I have had it shut down a few times pretty close together after letting it sit exposed but if I put it under a blanket the shut downs stop..

Anyone think this could have something to do with the metal back plate contacting the battery? From my experience batteries and cold do funny things. I was thinking of trying to place a thin buffer of foam in between the battery and the back plate to see if anything changes.

Just throwing in my .02
[Captivate Q&A, Help & Troubleshooting] upNsmokeAllDay:
I left mine in the car for 2 hours the other day in 20 degree weather and when i came back it was shutdown and when i started it up it still had 50% battery.

I lost everything except root, even what was on the internal sd card.
[Captivate Q&A, Help & Troubleshooting] GSMinCT:
Hi all,

I haven't gotten into loading ROMs and stuff like that yet into my Captivate, but I decided to register here so I could chime in on this topic, as this is by far the best thread on the topic that I can find anywhere on the internet.

I am, however, somewhat of a geek/ power user. I use the device for a lot of texting, push Gmail, a few random apps (Angry Birds of course), occasional internet (browser) access, and an occasional short phone call here or there. I have an alternate launcher installed, and I use NoLED (amazing program) but the OS is stock. I keep the apps fairly regularly updated.

It's probably irrelevant, but I think it's using an old SIM that was originally activated with a Pantech Duo, and then used with a variety of phones including a pair of Moto V557s, LG C1300, Nokia 2610, and for a while with an E71-2 NAM. We're longtime Cingular customers.

I have a Captivate from late August, serial number starts with 1010, and it started to develop the random shutdown issue sometime in October/November.

It started pretty infrequently, usually when I put it on a cool (65F-ish) desk and left it there for a while, and only occasionally. It actually took me several shut downs to realize what was going on, because I thought I was just running low on battery, but then I realized it had 30+% battery.

The issue started to get worse for me pretty quickly, and it went to shutting down multiple times per day. When I went home to Thanksgiving break, the phone sat around a lot, and, maybe coincidentally, maybe not, it was cool in the house (about 60F), and it was sitting on a hard surface a lot, although it could also have random shut downs in my warm, soft pocket.

I read this forum, and finally gave up trying to actually deal with the issue, and installed the battery-slurping, but also life-saving Captivate Keep Alive application.

While Captivate Keep Alive has 100% worked around the problem, the combination of that and starting to use push Email with Emailed Facebook notifications (frequent) and additional apps means that I now have to charge the phone in the middle of the day, which isn't a big deal, but is still a bit annoying. Luckily it charges off of my laptop just fine, and I had an extra Micro-USB cable laying around.
[Captivate Q&A, Help & Troubleshooting] argus1185:
Yeah so that would be almost exactly what happened to my phone, except that I'm running on a Cognition ROM. So that would mean it's hardware issue. My S/N is also starting with the 1010 number. I asked for an RMA from Amazon that coming in on Monday, i'm going to flash that and then run battery test to see what's going on and see if there's also the same shutdown issue. Wish me luck. LOL
[Captivate Q&A, Help & Troubleshooting] GSMinCT:
Either that, or it's a software issue that's present in both the stock and the Cognition ROMs. Not sure how Cognition is made, so I can't really comment on that. Good luck with that!

I am not giving up my phone, as I have a lot of stuff loaded on it, a screen protector stuck to it, and I don't want to give it up for a period of time to get a new one. It has to be my favorite phone yet, even with it's flaws, and boot time that seems like Windows 95 that's never been defragged.
[Captivate Q&A, Help & Troubleshooting] argus1185:
Well neither do i, but i have i got it from Amazon, and they are sending the phone to me, and then ill send the "old" one back to them within like 48 days or something. So i wont be stuck without a phone. I'll just have to back up everything with Titanium. LOL
[Captivate Q&A, Help & Troubleshooting] GSMinCT:
Oh ok, does that back all of your apps and settings up? I have plenty of other phones, but none of them could really fill the role that the Captivate does of integrating text, voice, data, email, and whatnot. Yeah, I'm addicted it!!
[Captivate Q&A, Help & Troubleshooting] argus1185:
Yeah i would think it does, but you would have to have ur phone rooted tho.
[Captivate Q&A, Help & Troubleshooting] argus1185:
Quick update: I apparently got my new RMA phone in the mail last night suprisingly fast (it was supposed to come in on monday) I rooted it, and flashed the new Cognition 2.3b7 with UV/OC on it. And i charged the battery to 100% and took it off the charger, its been running without the sim card in it (cuz its in my other phone that i have yet to return) im gonna leave it on till it runs out of battery and pray that it doesn't "randomly shut down" on me like my old one. any suggestions on what else i should test it with?? Thanks for yall inputs btw! =)

Can I interpret your comment "...or anything" to mean that you haven't downloaded any apps from the market?
[Captivate Q&A, Help & Troubleshooting] checkers2884:
After I did my factory reset I haven't put on ALL of the same apps. I didn't reinstall a couple of games just because I didn't really care for them. I'm on day 10 without a random shutdown now. I'm thinking it could be some conflicts with apps and/or charging the battery fully. Not sure though. I feel like I'm in some sort of support group saying that I'm on day 10 without a random shutdown.

[Captivate Q&A, Help & Troubleshooting] commander2k:
Mine started shutting down last night AFTER I did a factory reset. And always when the screen is off. My phone is rooted with the 1-click speed fix...

I think it may be that I had the maximum cpu speed for "screen off" set to 200 (in SetCPU) I changed it to 400 and will see if it makes any improvement. I figure it should take as much as it needs, so setting it to 200 min wouldnt do anything for me. Reading a lot of these posts Im thinking it may have to do with how much processing speed the phone has when the screen is off. I dont know what it is stock, but still, I had the phone for 2 weeks and it never did that until last night.

The same problem

I have the same issue.

Phone already twice turned itself off during night.

It seems it goes to deep sleep and turns off...

- I do not use setCPU

- I have power saving setting OFF

- phone is rooted

- I use Task Killer ( not automatic, fully manual)

- I use JuiceDeffender

- My wallpaper is just image, not live.

- I did not do factory reset yet.

It is unacceptable for me, I can't exchange phone immediately, but will do that on Monday.

My first one i had no shutdown issues. My daughter locked me our of it with too many pattern attempts. I had it for 2 days so i just exchanged it. On the way home fresh out of the box this one shutdown 3 times. Thought it was the battery so i charged it at home. But nope. Shuts down all the time.

[Captivate Q&A, Help & Troubleshooting] RexEscape:
I caught it just before shutting down!

Okay, my turn to give my experience. It has been shutting down me now more often. It has shut down while plugged in during the middle of the night, while in my pocket and while plugged in at my desk at work. Just last night while walking outside in the dark I noticed my phone was lit up while in my pocket. It was inside my cargo pants, loose with no other items in my pocket with the phone. I CAUGHT IT JUST BEFORE SHUTTING DOWN! I ACTUALLY DID! It was glowing in my pocket so I took it out and looked. It was on the POWER OFF option where it asked me if I want to switch it to Flight mode, Silent or Power Off. I had not touched my phone in a while before that. Nothing else was in my pocket with it that might have accidentally pressed the power button. So I'm assuming this random shut down problem is software related (not a loose battery or some sort).

Just this afternoon I did a Factory Reset. The only App that I installed after the Reset was SMS Backup and Restore to restore my SMS database. In just a couple of hours you've guessed it -- it had shut down again. I'm going to exchange it tomorrow.
