[Captivate Q&A, Help & Troubleshooting] FiniteSM:
What we know so far.

This post is for the people who have not kept up with this thread, and with others on other forums.

1. It is not a user-software issue. It has nothing to do with what apps you install.

2. It has nothing to do with rooting / lagfix etc. Many people (including myself with stock rogers) have this problem, even after factory resets.

3. The lockscreen does not matter. Again, it is not a software issue.

4. A new battery does not fix the problem.

5. Cleaning the battery contacts does not fix the problem. It may increase battery life (or not), and it may fix another similar problem, but not this one.

6. Reported in revisions as late as 1009 in US and 10.10 in Canada (I am not sure if the US and Canada share the same revisions, and can easily imagine Samsung increasing the revision number for Canada, effectively making 10.10 actually 1009) If you have a later revision and have this problem, please let me know.

7. Return the phone if you can.

8. If you cannot return the phone, CaptivateKeepAlive is your best option.

9. Samsung may or may not be aware of the problem (officially anyways), and they may or may not have fixed it in later revisions. If someone has evidence of either of these claims, please provide it.

So thats where we are now.

Possible Problem:

1. There is a fundamental software problem, such as a component which monitors the battery level. Such problem may be able to be fixed with an update, or with 2.2, on the other hand it may not.

2. There is a hardware problem somewhere in the device.However, it is not the battery itself. If this is the case, the only solution is to get a newer phone without the problem (once they fix it).

So hopefully with some clarity from Samsung we can determine what the issue is, and what the best course of action is. I plan to phone them tonight myself, and will update once I have done so.If you have more information, please post it, however please be aware that we have systematically reduced the possible causes, so asking if people all have angrybirds installed and if that is the issue, or if everyone charges the phone at night, is pointless.

Thanks, and hopefully this helps everyone.

Using basic lock...no password and others with no sd card have had shutdowns :(
[Captivate Q&A, Help & Troubleshooting] toddvb:
That didn't last long. This one shut down with near full charge. The last phone only shut down when it was below 70 or 80% or so.
[Captivate Q&A, Help & Troubleshooting] Bigal77:
Wow awesome post....and outlook is GRIM! I'M ON DAY 26 with rogers captivate....i guess I should return but what if second one does same? Froyo only hope I guess
[Captivate Q&A, Help & Troubleshooting] johnny13oi:
Well this guy has 1010 and his shutdown as well. There is definitely something wrong with the software. If a program such as CaptivateKeepAlive works then you know it has to be a software problem. After all, how can a program fix a hardware problem? And also I have seen this happen to many other Android devices such as the G2 which is made by a totally different manufacturer.
[Captivate Q&A, Help & Troubleshooting] FiniteSM:
First, you can't compare it to other manufacturers, as they might have a similar problem caused by an entirely different issue.

Secondly, you must remember the software is what controls the hardware. CKA stops the phone from going to sleep. Which in turn stops any hardware which is normally activated when the phone is fully asleep. It has no bearing on whether this is a hardware or software problem. And we still don't know which it is.
[Captivate Q&A, Help & Troubleshooting] FiniteSM:
Are you in canada or US? If Canada, then we know they share the same revision numbers.

One more data point

On Rogers. Captivate revision 10.10.

Shuts down whenever it is left in a cool environment , i.e. much below room temperature.

This is 100% repeatable: if I drive to work with the phone in my pocket, it's fine. If I put it on the car seat (my garage is unheated, so the interior of the car is not too warm), it's off by the time I get to work.

Called Rogers, they're exchanging it and shipping me a new one.

PITA, but hopefully the new one will behave itself.
[Captivate Q&A, Help & Troubleshooting] rdubz:
I've had no shutdowns in 2 days. Problem starting appearing tuesday, this week.

I've mentioned what I've changed in previous posts. I'd like to see if I can replicate the cold issue.

My battery is at 93%, wifi off, edge data, brightness @ level 2.

Lock screen - standard not pattern

I un-installed captivate keep alive last night, charged the phone to 95% and then left it unplugged on my nightstand. It was alive when I woke up this morning.

I'm going to take the phone outside for 5 minutes, I've got a new one coming from Rogers, anyways.... it does have a rubber case around it, just for information purposes.

Here goes.
[Captivate Q&A, Help & Troubleshooting] Bigal77:
Well mine is completely unrelated to weather, happened in my pocket today. I just turned off automatic in network settings, I put GSM only and its been 5 hrs with no shutdown. I will let you know if that changes anything. I will call Monday and ask for a replacement, on my day 29th. If the replacement has shutdown issues, I will keep until froyo update in Mid december or so.
[Captivate Q&A, Help & Troubleshooting] rdubz:
Agreed on the cold issue, mine was fine outside for 10 minutes today. Ill note too that i'm not positive but I think its been on edge as long as it's been awake. I have to out mine on edge @ the office as our reception sucks there. Anybody else use edge alot? I find myself not changing back to 3g due to lazyness and no real need.

Thoughts? Just got notification today about the new one shipping. I wonder what they'll say about replacing my 20 dollar screen protector :-)
[Captivate Q&A, Help & Troubleshooting] Bigal77:
Ok, so I switched from AUTO to GSM only after my last shutdown at noon.

It is now past midnight, and my phone died (battery at 0%) I had no shutdowns since i switched to GSM only (possible cause is the auto feature, and switching from edge to 3g???)

I will report tomorrow after my phone is charged. If it doesnt shutdown all day, I will be convinced its this. Ive had 8 shutdowns in 48hrs, all randomly, never wake up to the phone dead, just throughout the day.
[Captivate Q&A, Help & Troubleshooting] jswclw:
My observations

In my own case, I have has this phone since August. My normal practice is to charge all night, every night. It generally comes off the charger at 5AM. Usually I do not have a shutdown, but they do happen. Over the course of the day, I generally look at the phone to do something at least once an hour at a minimum. When it has shutdown, it is generally it has been in the mid to late morning. The battery is generally in the 90% - 80% range by then.

I have found that I can pretty much guarantee a shutdown by taking the battery to an extreme. If I discharge to below 20% before charging, or if I "reset the battery" by charging to 100%, turn off, charge to 100% again and so on, a shutdown in the subsequent day is almost guaranteed.

The other observation has to do with my location. Almost all shutdowns have occurred at the office. Based on the previous posts here, maybe the reason has to do with the 2g/3g switching. At the office reception is terrible. I'm sure there is a lot of switching between modes. At home, where it has only shutdown 1 time that I can remember, reception is 5 bars with good 3g. Also at home, it is on WiFi for what that's worth.

In the coming week, I will lock it into 2g at the office and see what happens. Unfortunately (actually fortunately I guess) it tough to test since it is so inconsistent.
[Captivate Q&A, Help & Troubleshooting] FiniteSM:
I exchanged my phone last night, and so far so good. it survived the entire night, and I noticed it actually sleeps.

I would like you guys to try something for me.

First, you will need SpareParts, which you can get from the market for free,

and BatteryPlotter, again free from the market.

I noticed two things different about this phone: In SpareParts, it reports running time as much lower overnight. This is when the phone is asleep, it shows wifi as 100% (which i left on), but actual runtime is 10%. Which includes some usage by me before bed. My last phone showed close to 100% runtime.

And the other thing, my battery life is SO much better on this phone.

In 10 hours, i lost 4% of my battery on sleep.

On my last phone, it was impossible for me to get any better than 2-4% an hour.

I'll let you know how things turn out with this one.
[Captivate Q&A, Help & Troubleshooting] FiniteSM:
If your at home and on wifi, then your not using a data connection, and theres no 2g/3g switching. You should try and see if you ever get a shutdown at home while on wifi.

In general though, it sounds to me that there are multiple issues people are trying to address.

I do not believe the 'shutdown in cold' which is easily replicated is the same as the issue most of us are talking about here. And perhaps there is an issue with 2g/3g switching, but I don't think thats the issue here either (My last phone didnt even have access to any 2g or 3g, because it wasnt activated yet, and still had shutdown problems).
[Captivate Q&A, Help & Troubleshooting] harold50:
I just gave up and called at&t for a new phone.I bought it in sept. new off of ebay and was not sure that i had any warranty. At&t said i have a 1 yr warranty,just from the serial number and they were very kool about the random shut down.

They are sending new phone in mail( no charge)

That being said, i have had some luck with keep alive--but the phone should work with out this app!!!
[Captivate Q&A, Help & Troubleshooting] obelix74:
Oh wow, am I the only person who doesn't see this 4 digit version on their phone?

I see 10.07 (not four digit).

There is a SKU, a Model, an IMEI, a FCC ID and a number that is like K43CE0168.

I don't see a four digit number with version as you guys say.

fwiw, I have now used this phone for over a week with the Odin Froyo ROM. I rooted the phone and deleted a bunch of AT&T stuff and random processed died on me after that. I noticed that it shut down ONCE after the rooting.

So I have now gone back to the stock Odin Froyo ROM and not rooted. No shutdowns in the last 3 days and I have installed about 30 apps so far and using it normally.

I will keep this thread posted. But I just can't find the version numbers you guys are talking about :).
[Captivate Q&A, Help & Troubleshooting] obelix74:
I am running the Odin Froyo version on my phone and it used to shut down on this. Agreed it is an unreleased version, hopefully the official release will fix it.
[Captivate Q&A, Help & Troubleshooting] obelix74:
Yes. I installed the leaked 2.2 ONLY to see if the shutdown stops but it didn't. I am now running 2.2 on my replaced phone. Fingers crossed.
[Captivate Q&A, Help & Troubleshooting] rdubz:
I could be wrong, but I disagree. 3/2G also has to do with voice as well. I get terrible voice reception at the office on 3g, as its constantly trying to find a good signal, if I drop to 2g, my calls come in clear, and are less likely to drop.

Also, when on Wifi, txts do not transfer via that, they are still using your network data to reach your phone.

Also, I let me phone totally die last night, turned it on today, and it died immediately, so I know the battery was as close to dead as possible. I've been charging it, in ON mode, for about 2 hours. I'll unplug it, keep it on 2g, and report back when I get home.
[Captivate Q&A, Help & Troubleshooting] Bigal77:
Me again

Ever since i switched to GSM only, i have yet to shutdown. I left it on all night without charging and still working since noon yesterday. This really seems to be it, but im only on edge now.

i will call monday to get a new phone, so i will keep testing this one
[Captivate Q&A, Help & Troubleshooting] rdubz:
Phone was running fine for 3 days. Today I charged it to 100% (I've done this already in the last few days) but when I unplug it's always dropped to 98-97%. I still get great battery life, but I decided to plug it back in, battery stayed at 97%, and then in about 15 minutes it told me it was full again.

Unplugged, phone began shutting down again. I really do think it has something to do with the charging/battery system.

The phone says it's fully charged, but when I unplug, it drops 2-3%. I'm using android system info to give me my percentages. Maybe the issue is, the phone is charged, but mis-reporting to whatever monitor program we're all using, as I'm sure not too many are using a stock battery meter, and even so, samsung probably didn't write the code for the stock meter itself (which never seemed to report properly from the beginning anyways)

then I plug it back in to make it 100%, and this is confusing the hole system. I can't see it being a serious hardware issue across this many revisions, locations, brandings of the phone. Remember, this isn't just happening to the captivate, but all versions of samsung galaxy S are having it. Its happened, but if it is really hardware, then this is the worst thing since the xbox 360. Or even sliced bread!

Phone dropped to 75% and immediately stopped shutting down.
[Captivate Q&A, Help & Troubleshooting] jswclw:
As I said in my earlier post, that act of "topping off" the battery definitely seems to play into this. I do get a lit of the shutdowns, but I usually do following one of those extra charges.

Last night I took the battery to the other extreme - 1% left. Charged all night. This morning, phone said it was fully charged, but reported 98%. I didn't put it back on the charger, but my impression has been that either extreme on the battery will cause a subsequent shutdown. We'll see if I get a shutdown today.
[Captivate Q&A, Help & Troubleshooting] jswclw:
As expected, I just had to wake it up from a shutdown. Upon reboot, it is at 93% battery. If this plays out as usual, that will be the only shutdown today.
[Captivate Q&A, Help & Troubleshooting] kegobeer:
Call the warranty department and exchange your phone. That's how I solved my shutdown problem.
[Captivate Q&A, Help & Troubleshooting] warrior100:
me too did warranty phone replacement, battery life seems a lot better too even with wifi and display sleep enabled, bluetooth with no CKA..
[Captivate Q&A, Help & Troubleshooting] Bigal77:
I have yet to get a shutdown since i switched out of auto network. I am now on HSDA only network, (edge is to slow) and I will report back.

My battery also tops at 97-98, but when I charge overnight, it reaches the full 100%, i never get a shutdown at morning, only during the day on standby.
[Captivate Q&A, Help & Troubleshooting] FiniteSM:
So far my new phone has held up, but I'm holding my breath as my first one was fine too for a week.

One thing you guys mention is 'charging overnight'. According to the rep I spoke with when i was exchanging my phone, a problem many people face is when they first get the phone, and subsequent uses, they charge overnight. Apparently you shouldn't have it 'charging' at 100%. I don't know if this is good information or not, but I find my phone charges very quickly (particularly when off), that I don't know if you really need it charging all night?
[Captivate Q&A, Help & Troubleshooting] Sulphur4724:
I charge it at night now so it doesn't die. Haven't had it die even once while on charger. Since it is my alarm clock is kinda impotant. (too me.)

The only thing stopping me from this is at least half the replacements I've been reading about have the issue too.

itsa PAIN! :)
[Captivate Q&A, Help & Troubleshooting] jswclw:
And again at 88% a couple hours ago.
[Captivate Q&A, Help & Troubleshooting] Bigal77:
why am i being ignored?? Have you tried setting your mobile network at HSDA only, and remove AUTO?

2 days with no shutdowns and counting

Battery life exceptional

With 3 hours use, and 10 hours not charging im at 41%
[Captivate Q&A, Help & Troubleshooting] rdubz:
Big Al, I started the removing of the auto, its still not the issue. I've been able to "turn on" the shutdowns again by fully charging my phone, pulling it, and then charging it again.

it started shutting back down even on GSM/HSPA only, not on auto mode. I was able to stop it from shutting down by physically turning the phone off, instead of letting it shut off, and then turning it back on. This serves as a sort of reset on the battery meter maybe?

I let me phone charge to around 90% today, went out, no shutdowns. I'm going to charge it to 100% now, let it drop to 98% when I unplug it, and see if it shuts down.

The issues revolves around fully/over charging the unit, and/or the phones ability to detect what charge its at. Also note that using a battery meter that shows percentages, might be wrong math, or wrong anything, it could be written for another phone, and may not be compatible with the captivates way of telling you the battery is full.
[Captivate Q&A, Help & Troubleshooting] eatonjb:
Anyone come up with something,

I had 3 different firmwares , 2 with 2.2 and one stock 2.1 and i have the same problem when just sitting around idling.

if the phone is active, like I check it over and over again, its fine, but when I go to sleep and it is NOT charging, it will shut down!
[Captivate Q&A, Help & Troubleshooting] Bigal77:
hmmm not really sure

I charge my phone for 6 hrs a night (as i sleep) , i havent changed my pattern and have had 2 days with no shutdowns. My shutdowns dont occur at 90% or above, its sporadic. I had at 24%, 41% 74% that i noted, plus other times throughout the day.

Ever since i removed auto, its worked for me.....so far that is.

I believe its more than 1 issue. Other have their phone shutdown at night, or by overcharging. sooo weird

I guess i should call and ask for replacement just in case, it will be 29 days tomorrow
[Captivate Q&A, Help & Troubleshooting] sschrupp:
Wow! Thanks so much for this tip! I've followed every other procedure to the letter before and never got much more than a day before I had to charge. Bump charging, battery callibration, battery resets, charging fully before flashing ROMs, etc. I'm a computer programmer and terribly meticulous when it comes to following directions. So I'm confident that anything that could be done I did, and I did it perfectly.

Well, after this I'm sitting at 2d 15h 4m 20s since unplugged and I still have 31% battery left. Holy moly!

And no, I didn't flash a new ROM or do any battery rituals before I tried this besides charging to 100% first. So on the current ROM before this I was squeaking out maybe a day and a half at most. After this tip over two and a half days and still a lot of charge left to go.

I'm definitely going to be doing this to my wife's captivate. Thank you!

(and sorry to those having the shutdown problems. My wife's was doing that and I updated her ROM to one of the latest Cognition and it stopped shutting down. It's too bad something so simple doesn't work for the rest of you.)
[Captivate Q&A, Help & Troubleshooting] Bigal77:
I did this last week and.it shutdown few hours later. Battery lasts about the same. Maybe ill try again with a little more alcohol....rubbed the qtip against a swab pad of alcohol I had
[Captivate Q&A, Help & Troubleshooting] rockr09:
I have been having problems with random shutdowns too, the thing, it seems it has to do with the temperature. When it was warmer earlier this year my phone never shutdown. But I noticed it would do It when I was inside and had it by the air conditioner. And now here recently I was hunting and it was around 30 degrees outside and I couldn't keep the phone on for more than 5 minutes. But as soon as I got inside in the warmth it stop shutting down. Just something I noticed I thought I would share.

This eliminated my problems. Doesn't use much more battery. I can barely tell. Been going several weeks without a lockup. I uninstall and it will lock up right away.
[Captivate Q&A, Help & Troubleshooting] flintdragon:
After factory reset and a new battery, my phone hasn't shut off in nearly two weeks. I've reinstalled pretty much everything that I had before. Obviously with so many changes, I have don't know exactly what may have fixed it. Hopefully it isn't coming back...
[Captivate Q&A, Help & Troubleshooting] evosky:
i use the CKA app, and it definitely keeps your phone alive. the reason for this i believe is that it opens up a ton of apps. i go to my task killer, kill a bunch of apps i dont need running, go out, then go back in after 5 minutes or so, and see that they're back up and running. i'm pretty convinced that the CKA is what's doing that.

for me, the battery life has actually gone down a decent amount since using it, needing to charge every day (instead of every 2 days or so before), but i guess that's a small price to pay for not having to restart my phone every hour?
[Captivate Q&A, Help & Troubleshooting] toddvb:
For those that are having shut downs shortly after unplugging from a full charge, next time power down right after you take off the charger. With the first two overnight charges on my replacement phone I had a shutdown within a couple hours. After last nights charge I did the above procedure and did not have a shut down today.
[Captivate Q&A, Help & Troubleshooting] tnt533:
I'll second that. A wind storm knocked out our power and we've been without heat for a full day in 20 degree weather. It started after sitting on my nightstand overnight in very cold conditions. Power is back on, the house and phone are warm and no issues.
[Captivate Q&A, Help & Troubleshooting] one028:
It is the cold weather that a causes the captivate to shut down.......i had my first captivate with me outside on a cold halloween night (35 degree s)...and my captivate shut down ever 10 minutes.....i returned that captivate nd got a ano ther captivate just recently...i have not had a

Shut off since I have had it......until today....i had the phone with me outside today and its 25 degrees....my new captivate shut off again every 10 minutes until I got back in my warm car......

It is the cold that causes the problem...this is BS..how am I suppose to keep this phone if I can't use it when its cold outside...

Put your phone in the fridge and test it out
[Captivate Q&A, Help & Troubleshooting] edessa:
No shut downs yet. The only thing I am doing different is that I do shut down the phone to charge it. It goes to 100%. I did clean the battery contacts as stated before and I get a little over 2 days with one charge.
[Captivate Q&A, Help & Troubleshooting] null_x86:
Ok, just got my 1010 Rev 0.4 about a week ago, and its been working fine till today, and this morning it started the shutting down issue. Only thing I've done to the phone is rooted it. Anyone know what causes this? Will the Froyo leaked build on here fix this?

Thanks in advance guys
