Just sharing my problem and thoughts.

Just sharing my problem and thoughts.

I have a 1007, I'm on cog v2..3b6. My battery charges, from ac, every night, when I unplug it it stays at 100%. If I ever unplug it as soon as it says 100% it drops to 97-98%. I have not cleaned my battery contacts... yet

My random shutdowns occur when I have facebook or the browser on the screen and the phone is locked. I don't know if it matters whether I lock it or if it times out itself. (When I say lock I mean push the button on the side to turn the screen off.) I also know that it happens more in the afternoon than in the morning so I think it may be more frequent when the battery % is below 65ish. These are the only factors that I have noticed that make a difference on my phone.

I also have the home button problem where it pushes itself sometimes. Both issues started maybe a month after I got the phone.

It was deer season last week and I let my phone sit beside me in the 40ish degree weather while hunting in the morning, no shutdowns. Later in the day while hunting or in the warm cabin I got more shutdowns than ever. Where I was hunting there is some 3g service so it goes back and forth. Just now I had a RS at work where there has never been any 3g signal, battery 62%, handcet popup that I didn't clear.

Here's what I think about the possible valid hypothesis so far and if they are affecting my phone.

1. Dirty battery contacts and cold weather could both be causing low voltage and could be the cause of some phone's problems but not mine.

2. Switching between 2g and 3g could be causing some of the problems, possibly mine, but at work, where I get some shutdowns I have never seen the 3g symbol on my phone. Maybe just looking for 3g causes it.

3. Someone said it couldn't be the os but if this is happening on different models from different manufacturers who are all using Android how could this not be the cause? I do not know that this happens for different manu. but I have read that it does.

I should probly say more but it's lunch time, gotta go.
[Captivate Q&A, Help & Troubleshooting] kegobeer:
If your home button pushes itself there's a hardware problem with the phone. My replacement phone had that problem, and AT&T sent me another one (this time a brand new 1010, which has no problems at all).
[Captivate Q&A, Help & Troubleshooting] topracer:
I have two Captivate (1009) activated at the same time three weeks ago, only one has the shutdown problem. Swapped the batteries, does not fix the problem. The Captivate Keep Alive set at 85% helps but does not fix the problem. Tried cleaning the battery connectors, does not fix the problem.

What's wrong with this phone?
[Captivate Q&A, Help & Troubleshooting] capn1:
It doesn't do it very often and all I have to do is lock the screen and unlock it again and it goes away. I guess I'd rather have my not-quite-right phone than somebody else's refurb phone.

edit: "Kegobeer" Nice, its a good thing you're not a dev, I'd hate to start buying kegs for roms
[Captivate Q&A, Help & Troubleshooting] Bigal77:
5 days with no shutdowns...ever since I switched to hsda only did it for me. I live in canada and it's always cold lol
[Captivate Q&A, Help & Troubleshooting] Pcsrule:
Ok I had this problem before I got a new replacement. Mfg date is Sept 19 on the battery. Haven't checked batch number. I thought it might be temp related too at first because the reported battery temperature was quite high. I thought this might have been a manufacturing defect that was causing the phone to shut off to protect the battery. That is until it shut off in my hand less than a second after locking it. I suppose it could be temp related still due to all the cold weather reports. Can't really test it as I live in California and it doesn't freeze here :P so long story short I got it replaced within 30 days at at&t store and it hasn't happened yet and its been two weeks. Two of my friends got captivates around the same time. Both ordered online and they have Sept. Manufacturing dates. No issues for either so it would seem as though Samsung has fixed it. So my advice is keep returning your device until you get a newer manufacturing date. Best of luck

Originally had a 1007 that shutdown. Today received a 1010 via rma from at&t. Will update soon.
[Captivate Q&A, Help & Troubleshooting] ajm786:
Had my 5th shutdown. Return the phone to ATT store and got a new one, same batch # (1009). Will keep you guys updated.
[Captivate Q&A, Help & Troubleshooting] jswclw:
Had 2 shutdowns yesterday. I have to say, they seemed to be temperature related. Both happened after a walk from the car to the stores. The phone was in my shirt pocket and I was without a coat, such that the phone felt cold when I noticed that it was off.

Tried cleaning the contacts last night. We'll see what happens.
[Captivate Q&A, Help & Troubleshooting] chasesavestheday:
to everyone with issues.. no need to try and diagnose this issue. The phone is faulty. Call at&t warranty center. Ask for android dept and get a new one. The phone has a 1 year warranty from the day you purchased. I traded an iphone for the captivate and they never asked about the original owner. Nor.did I mention. Just went along with it.
[Captivate Q&A, Help & Troubleshooting] tysj:
Wait so they warrantied your phone regardless of where it came from?
[Captivate Q&A, Help & Troubleshooting] Mastamind89:
I got Cog v2.3b4 yesterday and I also noticed that, right when I unplugged it from the charger it would from 100% to 97% instantly.

I'm gonna give AT&T a call on Monday and see if I could get a replacement, I rather not but I'm tired of this. My roommate has a Droid X and has also been experiencing some random shut offs.
[Captivate Q&A, Help & Troubleshooting] jswclw:
After cleaning the contacts yesterday, no shutdowns today. Even had the phone out in the cold for three hours, but it was busy playing music, so I don't think it would have shutdown anyway. So far, so good.
[Captivate Q&A, Help & Troubleshooting] fldude99:
Aren't all Captivates ATT branded? It shouldn't matter where it came from..they all came from ATT at one point
[Captivate Q&A, Help & Troubleshooting] tysj:
Interesting, do they mail you a new phone and then you send yours in or do they have to verify a problem first before mailing a replacement?
[Captivate Q&A, Help & Troubleshooting] spores:
Seems like cleaning the contacts helped me. I was down to 15% before cleaning and after i did the battery jumped to 55%. Seems like dirty contacts are causing increased resistance and consuming battery life.
[Captivate Q&A, Help & Troubleshooting] fldude99:
Did you clean it with something rough, like a nail file or emery cloth?
[Captivate Q&A, Help & Troubleshooting] jswclw:
I dipped a swab in alcohol, squeezed between my fingers to remove the excess, then just rubbed over contacts on phone, then battery. It dried very fast, but made sure it was dry before reinserting the battery.

Been more than a day now since a shutdown. When I make it through a week, then I'll really be convinced.
[Captivate Q&A, Help & Troubleshooting] Sulphur4724:
You can also scrub them a bit with a pencil eraser.
[Captivate Q&A, Help & Troubleshooting] jswclw:
Shutdown at 88%. Oh well. Interesting that 88% keeps coming up for me. There is something about that number for my phone.
[Captivate Q&A, Help & Troubleshooting] mpencexda:
Yeah.. mine is some where around 79% I believe.. I am attempting some focused testing to see if it goes anywhere..

[Captivate Q&A, Help & Troubleshooting] chasesavestheday:
correct, i traded my old iphone 3gs for the captivate to a stranger via a common website. (haha) it had shutdown issues, so i got ballsy and called the 1-800 warranty services number and went along with the questionnaire they had to diagnose it. basically they check the build/imei/firmware numbers, check for updates, battery/phone water damage stickers, etc. never asked where it was purchased nor when. by protocol they have to first try a master reset over the phone, send a new battery, then send a new device. took me about 2 weeks to go through the entire process to receive a new device.
[Captivate Q&A, Help & Troubleshooting] Smoghog:
I've been dealing with Samsung, myself. I bought my captivate from Best Buy and was out of the 30 day in-store return window before I started getting random shutdowns. They occurred only between 70-79%, and increased in frequency every day. I finally got fed up when the phone turned itself off 5 times in an hour. Samsung Warranty Center has had my phone for "repairs" for over a week now and their call center is staffed primarily with a bunch of clown-college dropouts who can neither tell me what they've done, what they're doing or when I can expect to get my phone back. I love the features set of this phone, and It's been a wonderful introduction to the world of Android, but I'll never buy another samsung phone after all of this.

This is on my second captivate, btw. The first had a different defect but I was able to exchange it in the first 30 days.
[Captivate Q&A, Help & Troubleshooting] jonjonk:
this problem is still not fixed? Problem has been going around since launch. This is ridiculous. Does the Other galaxy s phones also have this problem?
[Captivate Q&A, Help & Troubleshooting] specineff:
I got my Captivate on the launch date. I have no shutdown issue. I just got another one from Amazon to upgrade my wife's phone last week. I already had about 7 or 8 random shutdown since received the phone about a week ago. I am going to try the alcohol method to clean it else I will just call ATT for a replacement.

I have a few spare OEM samsung batteries. I notice sometimes the phone would last a few days without any shutdown on a battery, and sometimes I get a few shutdown on the same day if I use another battery. I am not sure if this issue is battery related.

Really frustrated...
[Captivate Q&A, Help & Troubleshooting] soopaflypriest:
Almost same situation here as well.

First Captivate randomly powered off 5 to 6 times a day after running flawlessly for almost 2 weeks. 1006 revision model

Exchanged it for my 2nd Captivate, 1009 revision model, flawless for almost 2 weeks and now shutdowns only when the battery is between 85% to 99% full and anywhere from 25 mins to 5 hours after completing a full charge.

I just sent it in today to Samsung warranty with a letter explaining the problem. I hope we both have some success in them figuring out what the issue is. I'm not as worried about the call center people, its a stressful low paying job. I just hope their techs are good enough to figure it out with the tools they have.
[Captivate Q&A, Help & Troubleshooting] caspio:
Just dropped my captivate in the mail for a wirefly return. It worked great for the first few weeks, but then started shutting down 5+ times a day. It's going to be a bummer going back to the old phone, but what can you do.

Just for reference, this was a 1009 model.
[Captivate Q&A, Help & Troubleshooting] pdiggitydogg:
Ive wanted to know this too. I looked around a little bit and couldnt find any threads for "vibrants", "epics", "fascinates", or the unlocked i9000s suffering the same problem, except for maybe 1 user. Possibly an att specific issue.
[Captivate Q&A, Help & Troubleshooting] sinichi21:
Has anyone tried reflashing back to stock? I think the setcpu is the main culprit here since maybe the kernel you are using does not support it. I didnt read the whole thread of this so if im repeating someone opinion sorry just want to help. my phone never experience these i used sertiron kernel if i want overclocking or downclocking using its voltage apk.
[Captivate Q&A, Help & Troubleshooting] M3Armand:
Folks, my Captivate is about 3 weeks old now. When I first got it, it would literally shut down SEVERAL times a day. I've read through this and other forums on how to try to fix it. I've cleaned the battery contacts and even "scratched them" to help create better terminal contact. Interestingly, I have not had a shutdown the past 2 weeks or so. I did not download that "always on" program. However, it did make me think that that program was on to something. My bluetooth has been always ON since I use a headset. I think there is some correlation there. I will shut off my bluetooth and see if the shutdowns re-occur and I will report back.
[Captivate Q&A, Help & Troubleshooting] avgjoegeek:
I did that today no go... phone kept shutting down for me after a full charge.

I really think it's a hardware issue at this point
[Captivate Q&A, Help & Troubleshooting] Paladuck:
My phone used to shut down. And then one day it stopped. I didn't do anything or tweak any settings.

It hasn't shut down in 3 months. I wish I had a clue why, but I guess it's better to wonder why it works rather than wonder why it doesn't.

This did not work for me. Reboots persisted even after this. I opted to trade out my phone for replacement after several.attempts to correct

[Captivate Q&A, Help & Troubleshooting] sinichi21:
did you do master reset after you flash stock? if you think its a hardware issue try using other battery if ever this doesnt fix it. maybe just get a replacement if you have warranty.
[Captivate Q&A, Help & Troubleshooting] StevenMP:
Phone specs as it relates to random shutdowns

Purchased 11-27-2010. I have a non-rooted Captivate 1009 revision 0.4 and battery 09-17-2010. It has the latest OTA update - JH7 or whatever. Installed several apps, some of which indicate they need access to the Keep Active (or Alive?) component in the phone. I created a morning work alarm. Phone shut down over night and yes I was late for work - NOT COOL. Yes it will be cold as people report. The aluminum back plate has no heat from the battery when it is off. The plate actually acts as a heat sink to disperse higher temps. It works much better than plastic.

Anyway, did a master reset of the phone and only installed my Hotmail and Exchange server settings. No apps installed, no alarm set. Phone did NOT shutdown.

Third day, reinstalled basic apps one right after the other:

Bubble Level

Kindle

NPR

Chase

eBay

I created a morning alarm. Phone shut down sometime overnight. No Alarm. Battery at 90+%.

Day four, master reset. Added Exchange and Hotmail. Will add alarm only and NO apps. Will see what happens tonight

Based on reading many (NOT ALL) of the posts it is possibly tied to defective battery lots (note the inside of the phone is screen-printed and stated compatible with 1000maH,batteries yet the battery is 1500maH), defective phone hardware even through lot date 1009, or 2.1 OS? So root cause is up for grabs still and YES ATT & Samsung have been less than stellar in talking about the issue. ALTHOUGH they did tell me to 'return the phone, the replacement you get will not have the issue.' When I asked why, it was met with silence and a repeat answer. I wonder if Job schooled them in schuckin' and jivin'...

Will report out on Saturday with either, my one-one reinstall of apps and overnight testing, or a new 1010 minimum build phone. I really want to like this phone, I really do.
[Captivate Q&A, Help & Troubleshooting] rljohnson:
Mine kept shutting off after I got it and I returned it. The new one did not make it past 29 days before a shutdown. It is getting more frequent but I have noticed the last 2 times it was after a recharge. Just something I am going to check on but I was wondering if anyone else has looked into this?
[Captivate Q&A, Help & Troubleshooting] mpencexda:
It is most common to get the issue after charging when phone is 85 % or above.. try the captivate keep alive app if you are not able tp swap out the phone.. I spent weeks trying to correct.. only thimg that worked was new phone or keep alive app

[Captivate Q&A, Help & Troubleshooting] ageros:
Just thought I'd throw in my experience with shutdowns. I've had the phone since shortly after launch and experienced no shutdowns until a few weeks ago they started.

Generally speaking all of my shutdowns happen between 6-11pm. I started testing things such as leaving wifi on one night and off another, disabling sync, and removing applications I did not use. Note: all of this I did while stock jh7 non-rooted.

I master cleared and odined the phone back so I could flash axura rc1. The first night after flashing I got a shutdown per my usual ritual. I noticed however that the phone was running fine that night, until I turned on my audible app for a few minutes to listen to part of a book. Shortly after was when the shutdown happen.

As it turns out I started using audible a few weeks ago. I drive usually around 3-5 hours a day for work and audiobooks keep me sane. So I stopped using the app, and its been 2 days now with no shut downs, and I haven't opened the audible app once.

I doubt this helps anyone all in all, but this is my experience so far with shutdowns.

Samsung tech replaced a TIB component in my 1009 rev Captivate and will be sending it back to me today. Should receive it early next week.

I'll keep everyone posted if it does the trick. Anyone else here send their Captivate into Samsung warranty?

Wonder what a TIB component is?
[Captivate Q&A, Help & Troubleshooting] india23:
Just recently I purchased a new Captivate from wirefly and was getting the same problem. It would shutdown after being idle for 30 seconds. I thought maybe it was the rom. so i flashed it back to JF6 (since it came with JH7). Same thing kept happening. Then today, I flashed the Assonance 3.0 rom and used a live wallpaper. That, for some strange reason, does not shut the phone off. reverted back to a static wallpapper and it turned off after being idle for 30 seconds. So I guess, try using a live wallpaper and see if that keeps it going.
[Captivate Q&A, Help & Troubleshooting] M3Armand:
Folks, just to add a data point, I shut off my bluetooth and I still have had NO SHUTDOWNS. The only thing other different thing that I had done was load a whole bunch of free apps. So maybe one of the things I loaded performs the same thing as that "always on" app that people are talking about. Here is what I loaded: Accuweather, Air Control Lite, Bartender, Battery Monitor, Converter, AAA Discounts, E Online, Fandango, Yahoo Fantasy Football, Fast Food, Jewels, Moviefone, Robo Defense, Solitaire, Super Battery, USA Today and Zillow.

Hope it helps...

UPDATE

My wife's original captivate had the shutdown problem *bad* so we returned it and got a free replacement. Both the original and the replacement are 1009 models, but the replacement hasn't had a single shutdown yet and it's been a couple weeks. So far so good and definitely goes along with those who say there is no fix for a phone doing this and that you have to get it replaced.
[Captivate Q&A, Help & Troubleshooting] eatonjb:
Ok.. my story has been.. I had a whole bunch of roms on my phone.

the phone shut down randomly, but i have really not had the time to do a normal test, but today, i have not fidget with my phone for about and hour with the BT on and it seems to be alive.. I am going to try a few BT tests and see if that does keep it working or not.

I also have some cheep batteries that I got on eBay that I am going to do some testing.

I will try it later and keep you posted
[Captivate Q&A, Help & Troubleshooting] gt50:
I read this entire post in the last two days. I have had my phone since August. I owned it for about three weeks before I got the first shutdown. After that it occurred about once per week.

As time has passed it has gotten worse. I have one of the phones that is fine until I take it out of my pocket at work, and leave it on a flat surface with a room temperature of around 70 degrees. It used to only happen at work. Now it is happening at home, since winter has hit. I do not have AC at home, and it is hard to get below 75 in the summer in socal without it.

I have never had a shutdown during charging. My shutdowns only occur at high battery level. I had decided to keep the phone in my pocket, but now I want to figure out the problem.

Today I intentionally put my phone in situations that would cause the shutdown and tried different things. I am running the latest cognition rom. I have tried cleaning the contacts. While my battery life seems to have improved, shutdowns continue. I have tested setcpu minimum at 100, 200, and 400. All shutdown. I have it set for 800, but my battery dropped into the 60's and my phone stopped shutting down. I will charge it tonight and continue testing at work tomorrow. If I get the shutdown with 800, I will try uninstall of setcpu to see if the contact cleaning worked, and setcpu was causing an issue.

BTW, I installed setcpu last night to try to address the issue. It was shutting down before it was installed.
[Captivate Q&A, Help & Troubleshooting] Jeffu:
Hey guys, new forum user, somewhat new Captivate owner.

Locking my phone to the 850 band helped it seems, but in the last few days I've noticed the shut downs coming back, albeit not as frequently.

One thing I noticed though that if I'm listening to music, as I am on my commutes to and from work that it doesn't shut down AT ALL. Which is weird though, I was beginning to suspect that the lack of activity was somehow affecting it, but I've gone hours with it being fine so in the end I have no idea at all.

Probably going to have to resort to the keep alive app. :(
[Captivate Q&A, Help & Troubleshooting] bztips:
Just to add my own experience...

Had the Captivate for about 3 weeks now. Shutdowns occur regularly once the battery level reaches about 75% or less. I know this is different from other users where the shutdowns occur right after recharging (and who can therefore use Keep Alive to help).

I'm going to see if I can just get a new battery to see if that's the problem, although from what I've been reading that rarely fixes the issue -- in which case I'll have to exchange for a new device before my 30 days are up.

It's sad that neither Samsung or ATT will fess up and admit there's a problem.
[Captivate Q&A, Help & Troubleshooting] gt50:
Using the 800mhz minimum cpu speed seems to be working. It shutdown one time this morning when I tried using 1Ghz as minimum and changed the setting from conservative to performance. This did not work at all. I locked the phone and it was dead in less than two minutes when I tried to wake it up.

My battery life is looking very good today. I am only consuming 3% per hour. This is with connection to wifi, email and exchange accounts getting push and tweetdeck updating every 3 minutes.

There may be some improvement in battery life due to the contact cleaning.
[Captivate Q&A, Help & Troubleshooting] M3Armand:
How did you even adjust the CPU speed? I assume you have your Captivate "hacked" in some way?

I'm "shutdown free" for 3 weeks so far... knock on wood...
