Due to further information from both the hardware and OS side of the house, it has been determined that this process is completely unnecessary for the Captivate.
You may still follow this procedure if you like or if it makes you feel good.
Good luck and God bless.

So, you are having trouble with your battery seemingly draining too quickly, especially after having flashed many ROMs/Kernels/etc...
It is possible that the problem (or part of the problem) is not necessarily the phone using too much power, but rather the phone not really knowing how much power you have left, or where 100% or 0% really are. If this is the case for you, you should see some results from doing the following:
(Do at your own risk. If your phone runs away and joins the circus I am not responsible)
1. Connect the phone to the charger with the phone powered on, and allow the phone to charge until it shows 100%
2. Disconnect the phone from the charger, and power it off.
3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the battery indicator shows 100% (you can use vol-up/vol-down to make the indicator come back up when the screen goes to sleep).
4. Disconnect the phone from the charger and power it on.
5. Use the phone as normal until it shuts off, then plug it in, turn it on and use as normal, charging whenever you like.
You should only need to use this sequence one time.
Hope this helps.

Yeah, I had it in a text file on my computer from a little while back, and was going to bump the topic but I couldn't find it anymore.
This may have to be done again after ROMs and stuff, so either bookmark this post, or copy-paste it into a document on your computer you can refer back to later.
Also, this give creedence to the age-old, often-debated theory that you should give your battery a full charge before turning on your phone for the first time...
It makes me sick when we have to do all this crap.

Sorry, it's a price we pay for messing with the software/firmware on the phone.
Also, if people did an actual full charge before using their phone for the first time, there would probably be fewer "Battery Life Sucks" threads...
Dont forget to boot into recovery after you full charged (adb reboot recovery or Power off the phone and then hold the volume up + Volume down + the power key. When it goes black the 2nd time release the power button and keep holding the volume buttons.) wipe stats Clockworkmod recovery -> advanced -> wipe battery stats.
Question for ya's.when I got this phone the att dude just turned it on and gave it to me without allowing for a full charge.should I go back slap him in the face and get a new battery and fully charge it before first use, cause its almost been two weeks and my batt life still seems kinda poor to me.
Also if I do that should I unroot and restore the att apps or will they not notice or bother to check that

Recalibrating may help slightly, but the Captivate just has a ****ty battery life. Read here, it was the worst in the entire test. No coincidence, the S-AMOLED's came in last in battery life and the S-LCD's came in first.

Without any details of how that test was performed, the results are meaningless.
I get battery life as good as my old iphone with the captivate. I wish it was better but it seems very competitive to me.

Something doesn't make sense since the Epic 4G has better battery life than the Captivate. Me thinks they didn't test these properly.

I can't even come close to the same battery life on this captivate as I did with my old iphone. I have to charge this phone every single night, where with my iphone I only had to charge it 2 or 3 times per week. I take it off charge every morning and by 10pm its down to around 20%. My old iphone I could go 2-3 days, and I do the same things on both phones. Checking facebook and twitter, playing a little bit of kingdoms live, a little websurfing, and checking emails, as they come in.
Same usage and 1/2 to 1/3 of the same battery life. Not so good.
Also, you cant say the test was meaningless because they dont tell you how they tested it. As long as they ran the same test on all the phones then a direct comparison of battery life is very legitimate and meaningful. But I agree, I would like to know what their testing methods are.

By old iPhone, do you mean 1st gen EDGE only iPhone? If that's the case, you can disable 3G on Captivate and get similar battery life.

If you go to the actual Laptop magazine post it explains
The test itself is fairly simple. Avram, our tireless Web director, modified the LAPTOP Battery Test we use for notebooks, and created an Android App that does much the same thing: It opens the phone’s Web browser to one of 60 popular Web sites, remains there for 60 seconds, closes the browser, then reopens the browser to next Web site on the list. It does so until the phone’s battery dies, all while recording the time elapsed.
Here’s how we set up the phones before we tested them:
First, we download My Settings and Advanced Task Killer, two free apps that are useful regardless.
Then, we open My Settings, and do the following:
Turn screen brightness to 40%, and turn off auto brightness.
Turn off Wi-Fi, Bluetooth, GPS location, cell location, and auto sync.
Deactivate screen timeout; that is, make sure the screen stays on indefinitely.
In the Web browser, we turn off Flash support and plug-ins.
We placed the phone in an area that was receiving at least 4 bars of service.
http://blog.laptopmag.com/android-battery-test-reveals-droid-x-lasts-longest-amoled-handsets-trail
Sounds about right to me although I dont think I could get 4.43 hours web. Most screen usaged I have gotten is up in the 3hour range.
I've done this on my captivate.. and I think it made it a little worse..
to be honest.. just leave it be and charge when you can.. lol hope for the best!
maybe other people will have better luck..
Many people also seem to have success with fully discharging their battery before charging it again for the first 2-3 times. Seems the battery learns its 'boundaries'. Many are reporting 20-30 hours after that with moderate usage.

I think that turning all of the screens to 40% brightness invalidates the results. To equal the playing field, the screens should be set to equal luminance.
My battery meter has been flashing 0 for 10 minutes now. Should I be worried? Should I return my phone? True story.

Hi all,
My 6 days old Sensation (Vodafone contract UK) discharge a huge amount during Standby (200-350mA). I got the number via Battery Widget Pro 1.65. For the first few days I did deplete the battery fully before charging it to full. Today I have factory reset it to the original condition at around 4pm with 58% battery full. Now at 9pm, it is only 18%. During this time, I spent about 1 hour with the phone, the rest is standby. I set the widget to monitor with 1 minute interval and when looking at the log file, it can be seen that the phone consumed from 200-400mA during the standby time. Coming from HD2 with Android modded 3-8mA standby consumption, this is a huge huge dissapoinment!
Is this because of my battery or is this my phone? Should I ask for a replacement? What about you, did you see similar pattern?
Thanks,
Duong

Ditto!! So annoyed since I too am coming from HD2 where HyperDroid's consumption had dropped to a flat 2mA in standby. This is insane for a native android device. Not to mention the heating while playing games and most importantly, the front facing camera producing upside down image during fring video chats.. grrr!
Dunno what the cause OR solution is (besides switching over to a custom rom if and when the BL gets unlocked and people like pongster develop for this device)...
Overall, sexy device but disappointed with such major holes left unattended..
A little offtopic but was a battery related questions and did not wanna start a new thread so posting here -
Does anybody know of if there's any app which can get the battery percent to show in the top bar instead of the default indicator?
Thanks

Any ideas on how I can do that? I tried using current widget but I guess because it's not rooted, current widget showed me a log of 0mA all throughout (yeah rite! hehe)
when I figure it out myself I'll let you know.
Current things I found that killed my battery over night: VTOK & Google Latitude
I went into Settings --> About Phone --> Battery --> Battery Use and checked, and it says display is eating most of my battery.
As far as mine, I get about 12 hours of battery life with standard usage, with the display eating most of the life, so if you're saying the screen is off, you might get different results...
over my 8h sleep battery dropped like 10%, nothing special (count in : wifi on, sync with gmail, weather) guys. new phone, fresh unoptimized kernel and radio. it'll get better. my prev phone (desire) was like sh*t at beginning in relating to its current spec rom ... and btw for checkin consuption : system panel (not lite), there is monitoring and u can see which apps running again if ya shoot them, check sync-s etc. many many thing to do, hard to tell in a single post

well it certainly sounds like a part of it is specimen issue.. here's my latest experience... last few times i have let it completely discharge and then charge back while the phone was off so i dont mess with it... once 100% charged, i switched the phone on and received a call.. a 25 minute conversation ate away 15% of my battery... LOL...
then, (now it gets better)... in 2 hrs of standby, the phone was at 60% which means it lost another 15% battery in 2 hrs of "standby".. im not sure if i can even call that state a "standby" anymore...
anyways... im wondering if its worth pinning hopes on rom development on our forum or should i just return this and go with something like nexus S which, O well, I can live with... atleast it has a 3300mA batterypack available... what's the use of kickass speeds and features if i have to use a phone like a desktop..
Hey, I have pretty bad battery drain during stand by as well I recommend trying to adjust the sync accounts, esp HTC hub and how often it updates that should improve it...I have a bunch of HTC widgets set up so im suspecting that being the reason for battery drain during stand by also adjust your email update setting accordingly. Every little bit helps!
Battery gauge stuck at 100%
Another one slightly off topic - but why start another battery thread.
It is the second day with my Sensation, and since I took the phone off the charger this morning, the battery gauge has been stuck at 100%. All other apps reading the battery status (e.g. Battery Widget) show the same number. I rebooted the phone multiple times, replaced the battery - nothing - permanent 100%. Has anyone had a similar experience? Did I get a perpetuum mobile ?
BTW the readings were fine yesterday.

Thanks for the pointer.. I will surely try that and see if it makes a difference..
That being said, call me crazy but it just occurs to me that HTC should be putting in some minimal efforts to check off basic quirks like battery consumption and QC. I mean all of us are spending a buttload of money on these devices year over year and then we rely on our devs here to give us basic functionality. Back in the days the reason people joined forums was to tweak devices.. Now it almost feels like we might as well expect only the hardware for the price we pay... disappointed!
Anywho...
I fully charged the phone before I went to bed last night. Eight hours later, the battery is at 10%. Is there something wrong with the battery?
Try using the Spare Parts app to see what's really using the battery in detail.
I just got a new battery for my phone from t-mobile and want to make sure to charge and break it in right from the start. I currently own a G2X and am a rookie when it comes to knowing about kernels, roms and etc (i have been studying little by little). I have a somewhat good understanding and have tried a couple things to get my battery life right.When I first got my G2X, I played with it right out of the box for about 5 minutes and the battery was at 30% from about 35%, then I only let it charge to about 80% and had to leave. I have ONLY had one good day of battery usage and that was after my first day of using setCPU & being rooted. It is currently rooted using the unlockr tutorial, "setCPU" from the market and have only one profile for "screen off" 216min-456max. I have read at least 70% of the battery threads about my phone already. I turn off gps, wi-fi and have screen brightness set to auto. Also I have deleted qik video, t-mobile account app and all the other major bloatware that comes with the phone but still get bad battery life. If you guys want, I can post a picture of my juice plotter battery stats. Please help me out i'm looking to bring in my new battery the right way or fix my old one and have the new one as a spare.
Edit:I put this in the wrong thread. excuse my noob/rookie mistake lol. sorry

hmmm.... did i not specify clear enough or what?
This has been covered in countless threads. You're battery life is not "unusual" Use the search Feature. Under the G2X general section there is a HUGE post on the second or third page about improving the G2X battery life.

I have a Galaxy Note and updated to ICS about a month ago....
Like many of you I also experienced fast battery drain, around 10% or more per hour, without usage. even more when I use it. 5 hours with moderate usage.
I am on unlimited data plan so 4G is always on.
I also tried fully charging the phone before going to bed at 11pm, woke up at 6am and battery already at 20+%, that's when I was sleeping, no use at all.
For a month, I have been charging my phone 2x a day!
I was very frustrated and wanted to go back to GB.
I was researching for weeks for the solution (also, checking for ICS updates almost everyday, waiting to see if Android had found a solution already), no one seemed to have a concrete solution, some suggest resetting, formatting etc.
These were so complicated for me I didn't even dream of doing them.
3 days ago, I accidentally switched off my 4G connection.
I didn't realize that the connection was off..
I was happy to see my battery charge was still at 98% after an hour, after 2 hours, light usage 95%.
"What's happening?"
Then I saw that my 4G was off.
Now, I was thinking 4G connection was the culprit... but I wanted to explore more and see if there was an app that could be causing this....
I checked my apps that used data and nothing was on, then I checked my sync settings, This is where I found out that I had so many accounts that had SYNC ON! Twitter, facebook, gmail, samsung e-mail etc.
So, I tried an experiment.... I stopped SYNCING everything.
It worked!
For one day, maybe 12hrs. (light usage with 4G connection on, just light usage, I checked my gmail by using the refresh button) 75% left on the battery!!! Wow!!
Then I thought "come on...gmail and android? Same owner/company right? I'm going to try to turn ON the GMAIL SYNC, I'm sure there won't be a problem"
I was right!!!
Now on my second day with 4G connection ON, Sync Gmail ON, medium usage, maybe 20-30min of phone calls, 30 or more texts, email and around 10 minutes of internet surfing.
9 hours unplugged and battery only at 70%!!!
I am very happy!
Oh, last night, I think only about 8-10% of battery was used (6 or 7 hours of sleep only 8-10% used....) nice!
For those who have not tried it yet... please try it... I hope it also works for you.
I just wanted to share my experience and hopefully help others that are, i'm sure, also already so frustrated with ICS.
I apologize for the long post.
Cheers!
so in other words disabling sync for apps that use networks poorly, over a high power useage radio.
its not really a solution, more of avoiding the problem . I know sync falls under android os in the data usage. which means to disable its bg data disables it all, so the real solution is to apply bg data restrictions to sync list as well to cover all ways of data access.
evidence of this is that Facebook ignores bg data restrictions( no big surprise there)
I think there is something wrong with my twitter app?
maybe I changed my password in my home page but did not change it in my twitter app and the app kept on trying and trying to log in but can't, maybe this caused the fast battery drain?
I didn't check it yet, maybe one of these days, but now, I'm happy... I really don't need to sync twitter all the time anyway.
Guys, check your accounts and sync... let us know what happens.
OLD NEWS.
Try this. My experience is on the AT&T Skyrocket, but from the research I've done both the Skyrocket and Note have the same problem. It's probably your charger.

jrockttu said:
You have CPU Spy, so run this test to rule one thing out:
1) Charge your phone overnight.
2) When you wake up in the morning, pull it from the charger and reset the timers in CPU Spy.
3) Let the phone sit idle for a few minutes with the screen off.
4) Refresh the timers in CPU Spy.
If your phone spent significant time at 384 mhz during that idle time and none in Deep Sleep, it's your charger. If it's deep sleeping, it's not your charger (do you use more than one charger?) To further verify the problem, restart your phone, let it sit idle for a few minutes, and check CPU Spy to see if it went into deep sleep after you restarted.
I have a couple of chargers that cause my phone to never deep sleep after I charge with them. The thing that remedies it is restarting the phone or plugging in to a "working" charger. It's a know issue, there's a dedicated thread in the Note forum where someone pinpoints the issue for the Note.
I researched a lot about battery problems on this phone, so list more specifics (do you always use the same charger, charge to full, apps, widgets, etc) and I'd be glad to help. Also, when you take a screen shot of your battery life like you did, take one of your screen on time as well. Since that's your primary drain, it's a good indicator of how your battery life is. 8 hours of battery life sucks, but it's really good if 4 hours is with the screen on.
EDIT: Here's the link to a VERY informative thread on the issue for the Note: http://forum.xda-developers.com/show....php?t=1519084

wow.
the more stuff you have 'on' on your phone, the more battery it will use. hmmm. Do you leave GPS on when your inside a building also?
I think syncing should not be put on auto. Unless on necessary apps like email. And... email only? Facebook and what not social app, keeping track on website when you want to is prolly sufficient. Unnecessary background data mining will without doubt drain the battery.
I will PM all senior mods here on xda and suggest you for 'Elite Developer'...you deserved it like noone else
This is not development and should not be posted in a development forum.
