Samsung Captivate :: Spontaneously Shuts Off - Short Battery Life
Sep 18, 2010
Ive been stalking the forums for a few weeks, reading up on all the issues and things associated with this phone and i can say ive experienced most of them (excluding rooting issues, i havent rooted).
*(of course) gps issues
*phone spontaneously shuts off and battery has to be removed before it will turn back on
*randomly awakes itself from sleep just to display the lock screen
*painfully short battery life
*no signal for a long time, have to restart phone several times before it returns.
These have all plagued me horribly the past month or so. then today it decided it wanted to....::gasp:: behave?
My battery still had half its life left when i got home tonight and its usually dead or yelping for a charge by that time (activity/usage the same today too). pages loaded quickly today and i had a signal all day.

I've had it for about a week now, and hoped it would get better, but it's just been atrocious. Much much worse than my stock rom ever was. I'm out of ideas. Does anybody know the latest radio version that CM will work with? They say "install the latest radios" but I have no clue where/what radios those are. Hopefully that will be something to help me.

Well lately my battery life has been horrid. If I am lucky I get 7-8 hours. That's with little to no internet use and just texting. Like now I'm at 70% and my phones been unplugged for 1 hour and all I have done is text a little and browse Facebook via the app for a little. I'm using BB .4 with the stock kernel. I was gettin better battery life than this before.

I got the fantastic Desire friday and I'm really enjoying it so far coming from iPhone and Hero.
Unfortunately I've run into a little issue: Up time and awake time (in Settings>About phone>Battery) are almost the same, meaning that the CPU never correctly throttles down when the phone is asleep. This is causing battery life to be rather short - On average I get 10-15 hours out of the phone with moderate settings.
By going to the battery info console (type *#*#4636#*#* in dialer) I managed to figure out that the calendar in some way is running and preventing the phone from sleeping (Partial wake in top dropdown). I did a factory reset and it hasn't seemed to help. There are 2 calendar related apps running: Obexservice and connectivityservice.

This is the first time I've rooted a phone, and i picked the Kaos Froyo V38 as the rom, but I've noticed since i did all of this my battery has been far far worse than what it was un-rooted. Today, for example i had my phone off the charger and on vibrate (with gps, mobile network off) and i was down to under 15% in under 5 hours. This is so much worse. Is it because i'm now running 2.2? What can i do to help this besides wiping the battery data (in the recovery menu)? I'm not really good with all of this yet, so some suggestions would be wonderful.

We have 2 new Tracfone ZTE Valets. Android 4.1.1 Mine gets 3 days of idle battery life while my wife's gets less than one day.
Charge both, unplug and leave overnight. Mine has 96% charge in morning, hers 65%.
The battery section shows Phone Idle and Cell Standby using about 33% battery each on hers. On her phone the WIFI is listed as using about 33% as well, while mine is 5-6%.
For some reason "The Weather Channel" on mine is listed as using about 50% battery, but charge lasts days while idle. (I assume the % means it's share of the power being used, not battery capacity)
The Tracfone "My Service" app/widget on hers was stuck 'pending reply' and using relatively large amount of data (17meg) while mine used perhaps a few k data. I assume it was repeatedly calling home. Uninstall/re-install and now it gets answer, uses little data (I include this just for recent related history)
Both phones are set to "Keep wifi on while asleep NEVER". From reading this should increase data usage on cell and perhaps even increase battery drain - but it doesn't drain my phone sitting right next to hers. 3-4 bars on cell service.
I read that "Location Services" could be turning the wifi on trying to determine location. It's true all three of the location options ARE checked, but again they are also checked on mine. GPS is ON on both as well. Bluetooth OFF, screen dim.

It is now 12:15 am est. My phone ate it's first battery for breakfast and lunch and died at 2:15. Left the house at 930 for school, sat in class and surfed the internet for a bit, made a few phone calls to meet up with a friend at the gym. Once at the gym I used Men's health mobile workout app(recommend) at which point my 1st battery died, Pop in my fully charged 2nd battery cruising through the day few phone calls nothing over 4 minutes, sat in class browsed some more and played wixel and what the doodle....went out after calss for a drink.
Finally my droid had ingested its 2nd battery timing out at 11. I am rooted running at 1200mhz with profiles set...Also having lots of problems with swype force closing....anyone experiencing the same problem? also I would like to poll the amount of droid owners having a 2nd battery.

I have been having some battery issues on my Captivate and can only seem to get through 12 or so hours with minimal use and it is quite bothersome. The main reason I bought the phone was because of its battery life and so far, I am disappointed. For instance, I charged my phone all night, woke up and made a less than one minute phone call, looked at my status and I was at 96%. As the day went on with minimal use, it seems to drain without me even touching it. As of now (13 hours later), my battery icon is blue and showing halfway full, but the battery status says 36% which does not add up to me. I also don't have a live wallpaper and have Advanced Task Manager that kills all apps as well as GPS and Wifi turned off. Any tips? Should I take it back and get a new one or see if I can get a new battery?

My Captivate has been plugged in for the past 2+ hours and I barely have 40% battery. Also, my charging cord doesn't stay plugged in. If I pick it up at all while it is charging, the cord falls out. I love this phone, but this may be a deal breaker. What are the chances these issues are just with the phone? Should I go to AT&T and get a new one?

I seem to be having what I consider unacceptible battery life and I wanted to collect some thoughts on how to improve it, or if I should seek remedy with AT&T or something. At this point, the phone is of limited use to me because it dies part way through the day, which is unacceptable. Normal routine. Phone charges completely overnight. I unplug my phone sometime in the 7am hour. I usually get my first battery warning around 3pm. Phone usually shuts itself off around 5-7pm (hence, a serious problem). Since the phone is dying, it is "cycling" the battery every time I charge it. My day is what I would consider moderate usage. For comparison, my Samsung Jack last a day and a half under the same conditions. My settings for display and other things are essentially stock.
I pulled the battery stats the last time the phone died just as it was shutting itself off.
Total time: 11h 49m
Display: 39% 1h 22m
Cell idle: 12% 10h 19m
Cell Standby: 25% 11h 41m, No signal 6%
Android system: 6% CPU background 22m, CPU Foreground 9s
Palringo: 6% Background 22m, foreground 3s
Android OS: 4% 12m
Doplhin HD Browser: 2% 6m 29s, 3m 58s
Android Core apps 2%
Good 2% 4m 50s, 31s

Is there any word on when an extended life (~2600mAh) battery is coming out? Is it already out?

I have done everything that I can think of in order to increase my battery life. I even took the old jeep to the shop to get the AC port fixed so I can charge in my car. I don't know if I have a genuine problem here or if I am just being picky. I know I have been using my phone more the past 3 days because it is a new toy and I can't keep my hands off of it, but I have noticed that the battery does not last more than 8 hour of normal use before it is completely depleted. I rooted it, removed the bloat, turned of GPS and Wireless assist, don't use WIFI, installed a task manager, and turned screen brightness to the minimum.
With all that being said the phone still does not last near what I think it should be. I have had it for 3 days now, so I am guessing what I am hearing from other people is that my battery should be broken in by now. I don't know what else to try. I noticed that when I check the battery use, the display is usually 70+ percent. Is there some day to decrease the brightness beyond the stock settings or something to increase life?Does it sound like I may need to do a battery swap. I know I have been playing with the phone more, but I feel like I haven't been using it so much that it should die that quickly.

My battery life has been pretty poor to this point, so I have been going from full charge to completely empty. I was doing that today when my phone shut off because it was out of battery. I then went and plugged it in for about four minutes, then realized I needed something so I unplugged and turned it back on, and now am showing 43% battery! I figured it was a glitch with the stock battery display, so downloaded the BatteryLife widget, which confirms I have 43%. Does this mean I need to complain to AT&T to get a new battery, or a new phone? Update: I rebooted the phone again and was at critically low battery life. I reseated the battery and rebooted again, and now I'm at 5%.

I have a friend that sent me this message today, which sounds like a great idea:
I've been messing with setcpu and trying out some underclocking profiles. Underclocking while the screen is off as well as reducing the CPU power has gotten me 75% battery left after 8 hours. This is with constant emails but no wireless, bluetooth, or gps. This is better than I was getting under windows mobile.

I upgraded my Captivate to 2.2 two weeks ago and ever since the phone will shut itself off without making a sound (screen just goes black like the battery was pulled out) randomly. I do notice it never does it if the charger is plugged in.
I also am having a problem with txting. Sometimes when I am replying to a txt to one person, it will sent the message to a random person in my contacts instead of the person I intended to send the txt to.
Lastly, when I take a pic with the camera or download a pic from a txt, it takes awhile for it to show up in my gallery...
None of these things were happening when it was still running 2.1.

I can't find an answer. New smartphone user. On the Captivate how do you send short codes like 332211? When I try the phone puts a hyphen in the middle. So using Google and I guess even regular dial it won't go through.

Well after trying evereything under the sun to get better battery life out of this vibrant, including atk, turning 3G off, installing battery apps, rooting, setcpu, lag fixes, now custom roms today. I finally know why the battery blows. I simply can't stop messing with this thing that is why! It's always in my hand like a nice comfort toy. Reminds of when the iPhone came out and I was hacking that thing to pieces updating unlocking jail breaking selling buying.

However, this simply has not been my experience at all, I get a couple of days out of my SGS whereas some others report only getting a day.
I just thought it would be interesting for us to post in here how much battery life we are getting for the amount of use we put the phone to.
There must be some sort of pattern.
My usage:
anywhere between 10 - 30 texts per day.
Several emails - sending and recieving.
a few phonecalls.
30 Minutes of gaming.
Twitter.
Live wallpaper running.
BBC News widget running and Weatherbug widget running.
I also listen to some music but this varies day by day.
3G and HSPDA are left on constantly as is my wireless.
GPS is turned off.
Thats my usage and i get at least a day and a half. Would be interesting to compare...

I know this phone isn't know for blinding speed (at least running it stock), but lately it's having trouble keeping up with text input from the keyboard. Is this normal? I am using taskiller to kill any not needed background apps and normally have over 120mb left in RAM. Any tips on what I can do to fix this? I'm trying to hold off rooting until I get the t-mobile update. Also, does the phone normally give inaccurate battery readings to the widgets? Because I am literally looking at the phone and watching the percentage go up... up 6 percent in the last hour. lol anyone else getting this?

This is a great thread to read on tips for saving power http://androidforums.com/samsung-vibrant/138944-how-save-power.html But this is something that people over look, its mentioned in a few places but I think it needs to be promoted more. I'm talking about, well I guess the word for it is conditioning the battery. Basically you drain the battery down till its dead(though in my case I went down to only 5%), turn the phone off and charge back up to full. One thing I noticed right away was how long it took for the phone to recharge. I have not hard data, but my experience up to that point was charging before didn't take that long. But now that I've done this, battery life is great. I've been listening to music for a couple of hours, some light browsing, viewed a youtube video, took a few pictures, and I have background sync on and I have both twitter and facebook installed with notifications set to their shortest time span(15min and 30min respectively). Currently at 8hrs since unplugged and at 61%. Not bad I'd say. I also have rooted my phone and installed the lag fix. I'm not running BH_MAN's cut down rom, I am still running stock.

Wow, I'm not sure what it is but my battery life has been horrible for the past week or so. Very minimal usage has me at 20% in 5 hours. This is unacceptable. The most I do is browse the web or play the occasional game for a few minutes. Recently I installed launcher pro, is this program known to worsen battery life? I don't even have that many programs on this phone. I see peoples screen shots with 7 pages full of widgets, I have 3 pages and only two are "full" of widgets.
I'm rooted, on stock rom, bloatware removed, and overclocked @ 1.2Ghz. I'm aware that overclocking is harder on the cpu and can worsen battery life, but my phone isn't always running at full speed. I have all my profiles set on conservative. When the screen is off I have it set to clock at 600Mhz max, 100 minimum. Does anyone know what might be causing the problem?
I heard that some custom roms improve battery life. What else can I do to improve battery life? If launchers can cause bad battery I'll just use touchwiz, doesn't bother me. I'd rather have good battery life over good looking screens. Also, my screen is on the lowest brightness setting for most of the day. Today for example, I had my phone fully charged. Took it off the charger and texted my girlfriend for a bit. Browsed maybe 2 sites on the web. I took a 2 hour nap. Woke up and played Nova for 20 minutes. I check my charge and my.phone was at 30%! Unacceptable. It was off the charger for less than 5 hours!

What's working for me is to recharge the phone with the computer cable. I was able to get a full day plus by doing this. For some unknown reason samsung didn't make is simple using the regular power cable.

I have a Samsung Moment, and the battery life is horrible. I always have problems with my battery running out before the day is over. That being said, my friend and I are in an engineering class and are working on a solution to the battery life issue. We have a survey we created and we really need some more results on it. We'd really appreciate it if some people would take it. Here is the link: Small Electronics and Battery Life Survey.

I have had my Samsung Galaxy S phone (Samsung Fascinate to be specific) for a full year now, and it wasn't until just recently that i have been having battery life problems. I could get a full days worth and more in the past, but now, my battery has been acting odd. I would usually charge it while I was sleeping, then wake up and go through my day just fine. But now, the minute i take it off the charger, it goes straight to being only half charged, and this is after 5 or 6 hours of charging.

So I painfully watched my Cappy's battery door crushed under my friend's car as one of their "harmless" joke. Now there's not a single site on the internet selling these doors, and I'm desperate. I found dummy/display Captivates though, so I was just wondering if anyone knows if the dummy battery door can replace the REAL door by any chance?
