Might not help everyone...

I had cognition on my captivate 1008 for a good 10 days with serious shutdown problems... ran captivate keep alive and that fixed it almost completely. However i didnt like this solution... I felt it was more of a band aid than an actual fix. I went back to stock with the odin manual 3button fix.... then did an odin master clear with odin 1click... then 1 click rooted it.... then flashed to assonance 5.2 and my phone works perfectly now.... no force closures, no shutdowns, no lagg, and i like the ROM a lot more than Cog... Just my experience with some personal opinion thrown in there, so take it for what its worth... but im very happy with the results.
[Captivate Q&A, Help & Troubleshooting] milli.kovach:
I just flashed assonance on my captivate today. Hopefully this fixes the random shutdown because i would rather not have to send it back if at all possible as it would likely take over a month for them to ship me one back to new zealand. I will post again with news on how well assonance 5.2 worked for me
[Captivate Q&A, Help & Troubleshooting] bababe:
poor me my Cappy still suffering even with Assonance 5.2. Still Assonance is SUPER. I LOVE IT SO MUCH. I wonder is there any actually functioning unit out there. I meant it looks like there is no end to this problem. ATT said it was a bad batch, but look. we still have new fone with issue. I actually really love the fone. I wanna stick with it. I wish someone with tech skill can tear apart the darn thing and work it out. You know one for everyone. COOK the fone.

Another guess of mine on the New Nexus S, alot ppl complain about Batt. life. I think Samsung put some hidden "KEEP ALIVE CODE" in there too keep it ALIVE hahahha:eek:
[Captivate Q&A, Help & Troubleshooting] bababe:
I just talked to one of my Korean buddy and he said that ppl in Korea have no shutdown issue with their (CDMA) Cappy. they only have problem with bluetooth and the odd placement of the power button. I dont know what he said is true or not but it is quite interesting. they have working units back home, but when converting to GSM, they somehow F**Ked up the whole thing:mad:
[Captivate Q&A, Help & Troubleshooting] LostPartizan:
Some of mine observations. I have cappy 1007 revision. It shut downs like hell when fully charged. So if it has 90-100% it will sure shut down as soon as I press power button. BUT if I heat cappy a bit - 35-40 celsius - it wouldn't! Could someone test this? I'm using *#0228# to see battery stats.
[Captivate Q&A, Help & Troubleshooting] mgfjd:
my Cappy shutdowns too... installed keep captivate alive.. waiting for results...
[Captivate Q&A, Help & Troubleshooting] bscode:
This is exactly what Captivate Keep Alive can help with, though it's a workaround so if you can get a new one from the carrier that's best.

[Captivate Q&A, Help & Troubleshooting] LostPartizan:
Not sure I can get replacement, since I'm in Europe, any ideas? I'm using CKA, but first of all I'm interested in solving issue, at least understanding it. So, just try to heat cappy for 35-40 celsius, maybe it will work not just for me.

Refurb

I just got a refurb (although I dont think its refurb) which crashed twice immediately. I called ATT and they said they would only do one exchange and to call Samsung. I called Samsung and they said i should remove all applications until it stops shutting down. I explained that would defeat the purpose of Android because applications are 90% of smartphones. HE said he understands that but i should remove all non-preinstalled apps. So i told him "thanks/wtf." Called att back, and they guy said he was sincerely sorry that 1) I was told i would only get one exchange and 2) that Samsung basically asked me to castrate the phone. Offered a DSC exchange.

I uninstalled smartbar (which was set to manual closes) and the xfinity app and I have not had a single shutdown.

All the apps on my phone are from the Market, non-rooted, no funny biz. IMEI is 90XX.
[Captivate Q&A, Help & Troubleshooting] psloan:
I had xfinity installed but not the smartbar. So I uninstalled xfinity. no change. my captivate still shuts down.
[Captivate Q&A, Help & Troubleshooting] bababe:
I wish someone works at Samsung service center or alike would leak how they actually fixing the power faulty units, so we wont have to all go running all over the NET asking the same question over and over again. :mad:
[Captivate Q&A, Help & Troubleshooting] Cazart:
I have been told that the shutdown issue is related to the reliability of the data connection, and the phone freeze is related to the cell radio connection. These are bugs fixed in froyo. If Your carrier has lousy coverage and it goes on too long, your phone goes down. I can say that after being told this and keeping a log, I believe that this is the issue. Whenever I have no data connection (lots, thanks Bell) I shut data off and get no shutdown.

Cleaning connections won't hurt you, but don't use rubbing alcohol. It contains mineral oil and that is BAD for electronics.
[Captivate Q&A, Help & Troubleshooting] LostPartizan:
Strange, my cappy shutdowns even without sim card. I don't use data connection at all, only wifi and gsm calls.

My shutdowns are related to battery voltage. If battery is full - 4.2v, shutdown are imminent. But when battery voltage goes down to 3.9-3.8v - no shutdowns at all. So there's some faulty chip in cappy IMHO.
[Captivate Q&A, Help & Troubleshooting] GTIVRon:
The shut down is battery related for me too it seems. Shuts down only when its above 52% and I lock the screen. Below that it's fine.

Also, flashing froyo (2.2) does not fix this issue. I am running froyo. I wish it would have fixed it. Having to kill my battery with a workaeijnd apparently the the point I can't get 12 hours from my phone with very moderate use is total bull****.
[Captivate Q&A, Help & Troubleshooting] Eschatologist:
Hey guys does temperature affect this shutdown problem? I was out stompin around in the woods yesterday (-15 degrees celsius) for an hour and the phone shut down a few times in that period...I have the occasional shutdown bug, but its never been this bad. (The phone was in my outside pocket and wasnt getting much body heat).
[Captivate Q&A, Help & Troubleshooting] NDub21:
I have an AT&T Captivate and the only time it shuts down for me is right after it is unplugged. I charge it only at nights and in the mornings I unplug it and put it in my pocket. A good percentage of the time it will be turned off the next time I check it. I have found however that if I do a few things on it, like check Twitter or browse to a website immediately after I unplug it, it won't shut down. It's rather odd, but as long as I have a workaround I can deal with it (still sucks though).

Mine is running Cognition v2.3b8 and is a model 1006.

But seriously Samsung, you better fix this with this 2.2 Froyo update (if it ever comes out...).
[Captivate Q&A, Help & Troubleshooting] LostPartizan:
Hey, could you make a little experiment? When cappy's battery is about 70% try to put it in your pocket or in another warm place (35-40Celsius). It should stop shutting down.
[Captivate Q&A, Help & Troubleshooting] LostPartizan:
There's a high probability of this.
[Captivate Q&A, Help & Troubleshooting] feilian:
My experience is more weird. When recovering from random shut down, the phone will be partially reset occassionally. The brightness, APN and other settings are gone.

My rom is stock JF6. ⊙_⊙
[Captivate Q&A, Help & Troubleshooting] ninjaclipse:
Its strange

My phone loves assonance 5.2. Any other rom I go to it has some kind of complication lol.. sleep death, gps, etc. I was a rom whore of sorts when i had an evo.

I switched to Serendipity 1.7 last friday, and for the next two days like clockwork. it would turn off while charging overnight. I would wake up and it would have the battery displayed and I would have to turn it on. I flash back to assonance Sunday, and its been great since. Never shut down once. If any one would like a log cat or something let me know..
[Captivate Q&A, Help & Troubleshooting] GTIVRon:
The phone is always in my pocket when I shut the screen off, so I am doubting the temperature issue.

I'm using Captivate Keep Alive app. It makes the phone to actually go into standby at whatever battery % you set it at. The downside is until that point it drains juice much faster.

It took me a while to get the 52% figure, since i went up on it a little bit every day. The day I went to 55% and it died, i restarted the phone, it was at 53%, so I set it for 52% and it doesn't die now till the battery is dead. usually around the time I get home from work ~10 hours after unplugging it from a full charge.

Are there any bugs with assonance? I might have to try that if I can figure how to flash ROMs. I installed the Rom Manager app, but it never works. Always getting some verification error.
[Captivate Q&A, Help & Troubleshooting] LostPartizan:
Try to setup all your settings, then power-down and power-up phone. Are those settings gone again? Possibly it's stock rom bugs.

How long does your phone lasts on assonance 5.2?

Maybe your pocket is not warm enough :). Anyway,it's just my observation. Maybe warming-up works for someone else.
[Captivate Q&A, Help & Troubleshooting] onelight:
Have almost the same identical problem as u on a model 1010..Tried several different roms and still getting it as well on various kernels...It's usually the first 7-10 percent or so that I need to drain myself after my phone is fully charged and it usually is fine after that. Hope a fix comes out soon.
[Captivate Q&A, Help & Troubleshooting] ninjaclipse:
It hasnt died yet. Ive had assonance 5.2 on it since this past sunday.

Idea

Anyone on Facebook - Everytime Samsung or AT&T posts anything about phones or plans for the future, there are a rash of Froyo comments. Comment about the shutdown and GPS issues there. Eventually maybe they'll get tire of seeing them and attempt to correct the issues. I also refer the folks lusting after Samsung phones here so they can see the other side of the coin, what's not on the AT&T and Samsung websites.
[Captivate Q&A, Help & Troubleshooting] Eschatologist:
This could also be likely source for me, since I am semi-rural and data can be inconsistent

Captivate Keep Alive App works Great

Your Captivate Keep Alive App works great. My phone rarely shuts down any more; Only twice since I started using it 4 months ago.
[Captivate Q&A, Help & Troubleshooting] cdwhit:
@Eschatologist - Strange, mine had a bad day yesterday also. Has anyone looked at when they are shutting down? The iPhone had a bug that the Alarm didn't go off on certain days. Is it conceivable or even possible that there is a certain time or calendar that triggers the shutdowns?

Just tossing wild assed ideas out.

After yesterday I'm going to have to break down and trade in my new phone for an old one and HOPE the issues are better since neither Samsung nor AT&T are will to check the replacements.

Is it worth trying to go through Samsung?
[Captivate Q&A, Help & Troubleshooting] Eschatologist:
Cliche aside, my bad shutdowns seem to happen in threes, FWIW...

Launcher pro and random shut-dowms

I just wanted to share my own experience with my captivates shutdown issues, hope it helps some people.

I originally rooted mine and flashed to cog 2.6 then to 2.8. With both, i experienced the shutdown issues. Being sick of it, i went back to stock. Bam no more! Soon after, i couldnt live with the stock menu and interface etc, so i went ahead and got launcher pro installed. A couple hours later it was dead. So i got rid of it and no more random shutdowns...

So if youre experiencing this issue, try uninstalling your launcher and see if it solves anything. It did for me.
[Captivate Q&A, Help & Troubleshooting] StuPastu:
My random shutdowns occur even on the stock rom with no other launcher or mod installed (as in, not even rooted...that was an annoying day wasted just to test hah).

Honestly I would have exchanged it already if it weren't for the fact that I bought the phone via craigslist and don't have a data plan. Thankfully I've learned to have some other device around as an alarm rather than rely on something that consistently yet randomly shuts off. I'm just going to wait for some official fix or buy a new phone if/when I renew my contract.

Random shutdown

Just thought I'd add my two cents worth to this thread:

I had minimal problems with the random shut-downs; just 4 or 5 times but I thought I might as well get my Captivate replaced before it got worse.

I called the 611 customer support line and the rep said he didn't know anything about the problem but that he would look it up. In a few minutes he came back on the line and said that it was a known problem. He told me to bring my phone in to any AT&T store and it would be replaced.

Two days later I made it in to the same AT&T store where I had bought my phone (the first day it was released). The first rep I spoke to said he there were no known issues with the Captivate but if I was having problems, I needed to bring it to the repair depot which was clear across town. I pushed him to check because the online rep had specifically said there was a problem. All he did was check my account to see that, yes, I had called in with the problem. He again told me I had to bring the phone to the repair depot. The paperwork he showed me said I would receive a "like new" replacement if they could not repair it. I didn't like the sound of that!

After demanding to see the manager I explained the problem and complaining that the rep was not doing anything to help me, I finally lost my cool and began yelling at him. He finally took me to a kiosk and looked up the problem. At last he found that there truly was a known problem but still insisted that they could do nothing and that I did have to bring the phone to the repair depot. After I got even louder and raised hell about being told to come into the store, he called his manager and asked for permission to exchange my phone.

He finally became very friendly and replaced my phone with a brand new Captivate.

Final results:

My old phone took forever for the GPS to make a connection - Now it is almost instantaneous.

Searches in my contacts frequently did not work. Now they work great.

Battery life was decent (for a smart phone) in the old phone but the new phone seems much better. It does seem to take much longer to charge the battery though.

Could not connect to my computer with or without Kies - Now I still can't connect through Kies but I can at least connect and transfer files. Still no tethering though.

Bottom line - The new phone is considerably better than my old model.

now they've replaced "COAXLE CABLE", whatever that is! was told they are gonna ship it back today. their ups shipping is slower than USPS first class. took them a week to get it from PA to Plano, TX. So should have my phone back next week sometime.

well second replacement for my wife's phone shut down on third day. My phone was shutting down every 30 minutes when exposed to -5C while in packet of my ski jacket.

This was enough to cal ATT again and request manager on the phone. Told them them how they are breaching contract and I am requesting brand new phones.

I should get a call ( on my work number) in few days.
[Captivate Q&A, Help & Troubleshooting] tmanonyx:
I went to the support center and all they had were phones in the bad IMEI range. They told me that they got the product bulletin and to wait for an update that should fix the issue. I don't know when this so called update will happen but I am going to keep the refurbished phone for now. It has only shutdown once so we will see. This is now week two. If it happens several more times I am going to try and push for a phone with a later build to be shipped to me.

Just want to share a little bit of experience. My cappy is model 1008, IMEI 6391 which is outside the bad range. I have random shutdown for random roms. Would like to share these roms with you guys.

Axura is my first and one of my favorites. It shut off once daily, mostly during charging.

The one that shutdown most often was Cappy's Gingerbread rom (which happened to be my favorite rom but oh well, usually the more you like something the more likely they take it away from you....) For that rom, it shuts off from 15 to 30 min. I tried setcpu and keep captivate alive app on it and it worked better, but the battery drain was not tolerable.

Using Cezar's Continuum now, was quite happy that it lasted 1.5 days without shutdown but it finally did today. :(

Anyhow I will keep flashing rom to see if the magic one comes up. Given the different shutdown timeframe, it seems to verify that different roms that require different CPU usage may have different results? Somehow disable lagfix seems to work better than the one that does. But its just a hunch.

Thank you everyone in XDA for their contribution. Great community to be in! (poor us captivate users who have problems... this is such a good phone.)

Bad batteries?

Pruchased captivate about two months ago and was having random shutdown issues with battery at >85%. Rooted and installed latest Cognition ROM - still had random shutdowns. Even though it did not make any sense as terminal resistance/voltage drop problems would be worse with nearly depleted battery, tried terminal cleaning - still had random shutdowns. Purchased extended battery from Ebay seller so I would not have to charge more than once per week and because phone was so thin that it was hard to hold on to. Have charged new battery 5 times in past month and not had any shutdowns. My idea is that OEM batteries are defective as non OEM battery does not have shutdown problems even though it stays >85% for a longer time (about 2 days in my case) due to its greater capacity.

ATT captivate

rooted with latest Cognition ROM

Seido extended battery

ATT GoPhone prepaid $100 (1000 minutes) per year SIM - no data plan - had ATT lock out texting and data use so I would not get $.20 per text or $.01 per Kb data charges.

Mostly use phone as PDA, GPS (CoPilot Live - all North America maps stored in phone so no data required), music player, and for reviewing CAD drawings. Average about 1 hour GPS per day, 90 seconds of calling per day, no texting or data, about 1 hour of WiFi per day, and about 2 hours music or general PDA use per day.
