You can try "Captivate Keep Alive" in the market, it just holds a WakeLock (aka keep the CPU on) until the battery is below a threshold. It's free and I think it works... but I don't have a big enough sample size to say that for sure. In the interest of full disclosure I did write it too.
[Captivate Q&A, Help & Troubleshooting] hcenteno21:
well it has worked for me for the last 3 days not a single shut down (compared to several shut downs every single day)...sorry i did not take the time to read all 48 pages before posting, I just thought I'd share what has worked for me. I know most people are saying to return the phone this n that, but a fix for a lot of people is better than getting a new phone..I myself have spent countless hours setting up the phone with the apps i like, and the tweaks i need..and would not want to go through that again...
[Captivate Q&A, Help & Troubleshooting] Jack45:
In fact, I'm glad it's working for you and hope your good fortune continues. You'll be the first person that I'm aware of that has found a way to prevent shutdowns. That said, since the cause has not been identified yet, there may be multiple problems that would serve as catalysts for the random shutdowns. You have, 'til now, experienced a particular catalyst that responds to WakeLock.
[Captivate Q&A, Help & Troubleshooting] samfeagle:
I'm going to try out your App, by setting the Threshold to 90% Battery, because that's where I normally charge the Battery up to to prevent the issue. I will let you know if it works for me. Thanks.
[Captivate Q&A, Help & Troubleshooting] RexEscape:
(This might have been discussed already so pardon me if has...)

I was on the phone with AT&T (Android dept) Warranty and they said that there is a GPS fix (or workaround or what have you) but there is no fix for the random shutdowns. They haven't been able to figure it out yet. These are the two main concerns with the Captivate right now. The Level 1 support does not have any record of this so-called random shutdown issue according to their database. B.S. Apparently, the different customer service departments aren't connected to each other. Boo!

I got this 3rd Cap on RMA due to this random shutdowns. I will get my 4th in the mail next week. Unfortunately, it will be a refurb. And, if it's still sick, they offer the HTC Aria as replacement. Boo...
[Captivate Q&A, Help & Troubleshooting] bassic101:
So far so good!!! Great little app there! Solved my problem and is saving me some battery life too (instead of having the Wakelock on all the time...)

I recommend people give it a try at least and see...

Live Wallpapers

I'm kinda going out on a limb here but does anybody who has had this problem been using a Live Wallpaper? I was just wondering because that was one of the first things I changed, because I figured it would suck the battery. Of course if some of you have been using a Live Wallpaper and still had the shutdown problem then oh well it was worth asking.
[Captivate Q&A, Help & Troubleshooting] RexEscape:
That was discussed before. Live Wallpaper, stock, or even custom, user-provided photos as wallpaper. We still get random shutdowns.
[Captivate Q&A, Help & Troubleshooting] avgjoegeek:
Sucks that this is one of the "undocumented features" of this phone.

I received mine in September.. had a ton of random shutdowns where i had to cold boot.

Along comes Cognition ROM - and that fixed it - I didn't experience another one until...

I fubard the phone while attempting to tweak it (circle battery mod). So I was stuck going back to OTA JH7.

Then I bit the bullet and put Cognition's 2.2 on it. It was running great - still no more shutdowns until recently.

But - come to find out I think it was an application issue not playing nice with the OS.

... so for just my own experience - I think my random shutdown issues are completely software related and not hardware. If your experiencing random shutdowns I would recommend attempting Cog's 2.1 ROM to see if that fixes the issue.
[Captivate Q&A, Help & Troubleshooting] kiltedthrower:
On my second Captivate. Still had issues. Flashed cognition 2.2 b8 on it yesterday and for the first time my phone didn't shut down at all, didn't shut down during the night, and hasn't shut down today. That's the first time in 24 hours it hasn't shut down once. I was shocked when it was still awake this morning.
[Captivate Q&A, Help & Troubleshooting] brokenbathr:
Does anybody know where we can get the source code for Captivate Keep Alive app?
[Captivate Q&A, Help & Troubleshooting] AlienHairball:
Well I just got two Captivates for my wife and me. Hers has been having the random shutdown problem since I handed her the phone. I thought maybe she just got a bad one, but this morning my phone was off as well :-(

On her phone w tried the captivate keep alive app, but it didn't help. We are both using many of the same apps, but I've read that there doesn't seem to be any one definite cause for this problem.

I will note that last night I went to bed with my phone fully charged for the first time and I know that some people are convinced this is related to fully charging, hence the keep alive app.

I'd say the next step for me is loading a custom rom on my phone and see if that addresses the problem.

/sigh. Love this hardware so much. Really hope to get this problem cleared up - hell even gps works fine on my phone, but I cannot keep a phone that randomly shuts down >:-(
[Captivate Q&A, Help & Troubleshooting] kegobeer:
Do you have an SD card in either phone? If so, you could try removing it to see if it makes a difference. It certainly can't hurt. I was having shutdowns at the exact same time every day, and when I removed my 2GB SD card the shutdowns stopped. Maybe it's a coincidence, but it solved my problems. (And, no I didn't change anything else.)
[Captivate Q&A, Help & Troubleshooting] bscode:
I don't have the source available anywhere right now but all it's doing is holding a PARTIAL_WAKE_LOCK WakeLock until the battery % is below the threshold you specify. The WakeLock is held by a service that manages the notification and receives the battery percent from a BroadcastReceiver. It's quite simple and if I get some free time :eek: I'll put the source on code.bluesteel.org. Interestingly enough there are no loops in the code.

Is there something in particular you're interested in?
[Captivate Q&A, Help & Troubleshooting] brokenbathr:
No, just a better idea of how your app works, which you provided. Thanks for the details and your app.

After installing Keep Alive, I've been running about four days now without a shutdown.

This is great, but in effect, I guess I'm running hardware clipped at 85% (default threshold), charge.
[Captivate Q&A, Help & Troubleshooting] SaltyFoam:
this is the same behavior that mine exhibits.
[Captivate Q&A, Help & Troubleshooting] AlienHairball:
This is certainly not a guaranteed fix, but here's my recent anecdotal evidence.

I got my Captivate a little over a week ago and in that first weekend I had 2 random shutdowns. I then rooted and flashed to Cog v2.1.6 and haven't had a random shutdown since. Not sure what to make of that, but at the moment I'm happy.
[Captivate Q&A, Help & Troubleshooting] skyhook8:
I took the original phone back after 3 weeks primarily because of random shutdowns and I've had the new Captivate for a few weeks now and have not had a single shutdown. If it were me and I was still in the 30 day window I'd backup my applications and settings and go get another one pronto. I think the poll shows that 53% of owners have not had a single shutdown so it appears to be hit and miss.
[Captivate Q&A, Help & Troubleshooting] shawnathan9:
My gf has this problem and I just seen it for the tine while all other occurances have been hear say.

I even bought her a HTC Aria to use while I checked it out. Without the sim card, the phone remained on for 27hrs while I randomly came back to it to check for any more power downs.

I used it for wifi, random tasks and it worked fine.

As soon as we put the sim card in and she got a call and then left it alone.... Five mins later of going back to use her phone and I noticed that it was completely off.

Has anyone tested the idea of this being a sim card/ radio issue?

Its running cognition and flashed from from bugless a while ago.

Personally, my evo has been running great without hiccups so im rather disappointed with the captivate when it has such great hardware :(

Perhaps the problem is partially related to the stregnth of the radio and/pmor network related.

Just chimung in with what I observed.

*Yes, I there are typos...but im sure you can translates... XD
[Captivate Q&A, Help & Troubleshooting] DragonPup:
So how much power does Captivate Keep Alive draw?
[Captivate Q&A, Help & Troubleshooting] pezx44:
It doesn't seem like it's sucking up too much. I run it to 81% and yesterday I had a fairly light use day and plugged in at night at around 60% after 18 hours. I know that's all very subjective, but my point is that it seems about in line with what I expect without running it. Another program I tried to fix it (Load Monitor) also worked but seemed to drain the battery noticeably.
[Captivate Q&A, Help & Troubleshooting] koreancanuck:
For me, I've had this problem when I first bought this captivate. I was freaking out.

Then I read it on XDA that this problem was actually not uncommon. I believe the shutdowns actually started when I rooted my phone. However, when I flashed the stock ROM again from ODIN and flashed cog beta7 (and the sequels later on) I stopped having random shutdowns. I don't know why, but I don't mind. I was really getting annoyed to a point where I was going to sell it and get a vibrant.
[Captivate Q&A, Help & Troubleshooting] esox23:
My take on it...

My first captivate had the random shutdown issue, so bad I returned it and almost never looked back, but I liked the phone so much and it was the only REAL option with AT&T that I got another.

New phone didn't have any problems, EXCEPT for when I go fishing (Twin Cities, MN) and the weather started getting cooler, if I put my phone on the dash of my boat in the cold/cool elements it will turn off (like clockwork), BUT if I leave it in my pocket next to my body where it stays warmer it never shuts down. This is aggravating because I usually have bibs on and digging out the phone is a big PITA. No my buddy has a vibrant and never has an issue.

In my case with the 2nd phone it's temp related, with the first phone god only knows.

Smart phones? I think not, more like stupid phones... :D
[Captivate Q&A, Help & Troubleshooting] NeoXerO:
Hey everyone!

Just gonna say that the keep alive app worked for me. I'd get random shutdowns in the morning after a full charge IN THE BEGINNING.

However, it progressively got worse and I started getting COMPLETELY random shutdowns.

Then, last week, I installed keep alive. Haven't had a problem since. Just to make sure, I turned off keep alive and let it sleep for another half hour. Guess what? phone shut off. Now I keep keep alive on till 30%. Hopefully they get this issue ironed out in the next update, though.

If captivate keep alive doesn't work, then I think it's almost definitely a problem with one of the applications you're running, because it seemed to work for most people.
[Captivate Q&A, Help & Troubleshooting] rainmanram:
I have random occasional random shutdowns that I'm trying to figure out and have been reading about. It just occured to me that I don't think I've heard of the problem happening when the phone is plugged into usb. I haven't had that happen either but I thought I'd throw it out there as a datapoint in case it strikes a cord with someone. I know there seems to be some indication of a power problem (keep alive, after charge, power management, etc) but I don't think anyone has had their phone shut down while plugged in, have they?

For another note, I've had the shutdown problem at my house and a day before going on vacation, I turned off automatic updating on my RSS reader and didn't have a shut down. I went on vacation and turned off WiFi and didn't have a shut down. Came home, enabled WiFi and started having shut downs. I'm going to start turning off my WiFi at night and see if it shuts down over night.

Cheers!
[Captivate Q&A, Help & Troubleshooting] DragonPup:
Here's a thought or two on the shutdowns that happen when the phone sleeps.

Could be it an program that operates outside of stock the Samsung/Android apps? It'd probably have to be something that is generally running at any given time. While I have nothing to back this up with, two of the few programs we all probably use are Handcent and Tapatalk. Does anyone want to be a guinea pig, uninstall them and see if the shutdowns continue?
[Captivate Q&A, Help & Troubleshooting] rainmanram:
I don't have either of those installed and others have the shut down with a stock rom.
[Captivate Q&A, Help & Troubleshooting] rainmanram:
Ok, after looking at tapatalk on the market, it might be the same as the xda app. Nevertheless, I've had the shutdown priorto installing it.

Hi every one Im new with android I just install SetCPU last night and start to have some funny isues, in a week or less Captivate ,the icons in every screen were gone I have to restart the phone,no wifi internet acces, have to restart the phone, and the phone start shutting down and drop call, uninstall SetCPU and restart the phone and everything is ok now no more problems ,att said if you have a old sim card can be a problem too to damage the phone, I don't belive but who know's I will try that too cya.............
[Captivate Q&A, Help & Troubleshooting] pkley:
First Captivate had the random shut down problem, second didn't but had the 3 button problem and I ended up borking the phone while trying to flash to stock. AT&T sent me another one.

This one also SEVERELY had the shut down problem, sometimes a minute after booting the phone back up it would be shut down again!!!! Now it seems to have stopped and here's the timeline...

3pm Tuesday received phone. Verified no 3 button problem. Waited for new 2.2.3 Cognition, couldn't wait any longer and flashed to 2.1.9. Had no problems all evening. Next morning shutdowns happened constantly unless the phone was being used. Tried the Keep Alive app, didn't help at all.

Called warranty and was about to start "troubleshooting" and we got cut off. Had to get back to work so couldn't complete.

Flashed to 2.2.3 Cognition doing a wipe as well. Reinstalled all my apps via Ti making sure I didn't restore any apps that weren't specifically installed by me. Haven't had a shutdown since!

Not sure it won't start happening again, but sure hoping it won't!

CRAP, CRAP, CRAP...in the middle of a conversation with tech support the phone cut off. AHHHHHHHHHHHHHHHH! Guess I'm calling AT&T again and getting another one...
[Captivate Q&A, Help & Troubleshooting] Nimocone:
I'm also a happy Keep Alive user. I keep it on til 80% and haven't had any shutdowns. And Rainmanram, mine has never shut down while plugged in via usb or the wall. It has even shut down in airplane mode before I got Keep Alive. Kudos to that author!
[Captivate Q&A, Help & Troubleshooting] Nickel Dime Bay:
I noticed that with the app Captivate Keep Alive, my battery was draining a little bit more. IDK if its just me though. Anyone else?

It does stop the shutdowns btw
[Captivate Q&A, Help & Troubleshooting] gordec:
Agree. I keep mine at 85% never had any issues. So I guess this means it's not hardware issues for those who resolved with Keep Live. Mine's stable for over 10 days now. GPS working like a champ in cloudy day. :)
[Captivate Q&A, Help & Troubleshooting] bscode:
I'm really glad Captivate Keep Alive is working for you guys!

I would expect the battery to drain a little faster while Captivate Keep Alive is keeping the CPU awake, which is anytime you see the icon in the Notification bar. I'm actually surprised it's not worse.
[Captivate Q&A, Help & Troubleshooting] Algorismus:
I am charging till %90 percent, and i havent seen shut down for two weeks. Dont do full charge.
[Captivate Q&A, Help & Troubleshooting] obelix74:
Should be an app

I am convinced that this is caused due to an app.

Untouched android phone did not crash for a while.

I updated to the GPS fix through AT&T and it didn't crash for a while.

I installed an uninstalled half a dozen apps and started to die on me. Not just during charging, during random sleeping.

Out of sheer frustration, I installed Froyo using Odin. Installed all my apps again, started to die on me as before.

I installed KeepAlive, it solved my problem of dying, but it kills the battery if I keep the battery % too low. If I keep it too high, it dies once the threshold is past.

I then flashed it with the stock 2.1 ROM using an old Odin, don't install many apps (just SwiftKey and Google Listen), doesn't die in a day.

I then flashed to 2.2 ROM using Odin, don't install many apps (just SwiftKey and Google listen), hasn't died since morning.

ie, I have got this to crash on stock AT&T ROM and installed ROMs - when I have installed many apps. Just don't know which app is causing this.

I am going to be very careful on what I install. Is there a way to debug using the developers toolkit or something AFTER a crash happens to look back at logs?
[Captivate Q&A, Help & Troubleshooting] rainmanram:
After reading this entire thread, it would seem that flashing the device can fix the problem or cause it to start happening. I mean this in a binary sense, happening or not happening. The act of flashing seems to be able to toggle that state.

The second common theme is that charging to full charge seems to be able to trigger the shutdown.

A third observation is that there doesn't appear to be any proof, one way or the other, if this is a software or hardware problem.

I'm tempted to believe that flashing is causing a random write. How that is related to battery charge, I have no idea.
[Captivate Q&A, Help & Troubleshooting] obelix74:
Not really. The problem started for me on the stock phone with no modifications other than installed software. I flashed it only to see if that fixes the problem.

OTOH, I just noticed that my battery takes nearly 12-14 hours to charge fully and never hits 100% charge and drains rather quickly and heats up as well.

I am beginning to wonder if it has something to do with a faulty battery. I am going to ask AT&T to give me a new battery first.
[Captivate Q&A, Help & Troubleshooting] kegobeer:
Did it take that long before you flashed? There's definitely something up if it's always done that.
[Captivate Q&A, Help & Troubleshooting] pkley:
It's not the battery, it's not the software, it's the phone...give it up and have AT&T replace it.

I got my phone (the third) on Friday, immediately flashed it to Cog 2.2.3b exactly as the previous phone, restored via Titanium EXACTLY as the previous phone, hasn't hiccuped since.

Of course the first thing I tried was making sure it had the 3 button recovery working, yup... So did the previous one...but not the one before that...

The last phone was obviously a refurb and had JH7. When I called 2 days after receiving it (actually one but I got cut off and didn't have time to call back), they sent the current one which seemed new (JF6). Incredibly enough they even went to the extent of setting up a followup call on Sunday to make sure the new phone was working correctly!

In reality this is now my 4th, the first had the random shutdown also which is why it went back to the AT&T store and I exchanged for a iPhone for exactly 3 days, which is when I could get the store to call my boss for approval to exchange again for the Captivate (which had the 3 button problem).

I repeat, it's not the battery or what software you're installing, it's the phone, replace it.

... My phone just randomly shut down for the first time in a month or so? :(
[Captivate Q&A, Help & Troubleshooting] dhncali420:
on my second cappy maybe going for my third

First Cappy had shutdowns from day one (on the way home from the ATT store). Flashed COG still shutdowns returned one week later.

Second Cappy stayed stock for 1 week (no shutdowns) couldn't take it had to flash to COG b9, day 1 shutdown (did factory reset and wipe data) on day 3 shutdown 4 times. Went back to stock for 2 weeks no shutdowns, couldn't take it flashed to Cog2.3b3 second day shut down GRRRRR!!!!

I guess back to stock and see if shutdowns still occur

I haven't tried swapping kernals but don't think that will help

This is exactly what Captivate Keep Alive prevents you from having to do, or you could use it as insurance for when you aren't staring at your phone as it charges. :D
[Captivate Q&A, Help & Troubleshooting] FiniteSM:
Software or Hardware?

Has anyone made progress on this problem?

I have only had my phone for 2 weeks now, so i could return it. However, KeepAlive is working pretty well, so if this is a software bug that will get updated soon, I'd rather keep my current phone, because a replacement will probably have the same problem until it is fixed.

Has anyone gotten a response from samsung?
[Captivate Q&A, Help & Troubleshooting] AlienHairball:
After the 2 shutdowns I had over the first weekend with my Captivate and then flashing to a custom ROM (Cog 2.1.6) I haven't had a single shutdown since and it's been about 2 weeks.

However, my wife's captivate has just reached critical mass with this problem. :mad: It was shutting down once in a while every few days, certainly not good, but then yesterday the phone went insane and would shut down if left in sleep mode for *any* length of time more than a minute or so. I counted 5 shutdowns in about 3 hours and that's only as often as I remembered to check it.

So I'm shipping that one back for an exchange. We'll see how it goes.
[Captivate Q&A, Help & Troubleshooting] toddvb:
Any luck with the replacements?

I've just had this phone a week and I'm having the same shut down problems. Mine are random, not after charging. Once or twice a day. Keep alive works, but drains the battery. It got me down to 74% in 4 hours today with no other use of the phone. After I shut Keep Alive down I only went down another 10% the rest of the day (even with the wifi on).

Should I get a replacement or hold on for a fix?

From what I've read I could get a phone with the same issues or more. My GPS works, no problem with the keys. I'd love this phone if it wouldn't shut down. If the replacements are working for the most part, I may go for it.

Is there any way I can get the app downloads off my phone to install them on a new phone if I get one? I've paid for a few and don't want to loose that. Otherwise, it's no trouble just to download them again.
[Captivate Q&A, Help & Troubleshooting] kegobeer:
The downloads will follow you. Once you log into the Market, go to the downloads and you'll see every app you paid for.

Mine started shutting down randomly after two weeks, returned it to AT&T. Now back to my slow iPhone 3G, at least it doesn't shutdown randomly on me.
[Captivate Q&A, Help & Troubleshooting] Zealotki11er:
I never used my Phone and flashed it tight away and its happening 4-6 times a day. Its not only Captivate that has this problem. I wonder if Samsung is taking taking too long with 2.2 Froyo or 2.3 because they dot have a fix either. Something like this should not require a fix from users but form Samsung them selfs. I hope they fix it soon because its not bearable. Might have to sell this and get something else.
