Killing my battery !! - Captivate Q&A, Help & Troubleshooting

Rooted and installed assonance 5.2 and put on some other apps now something is draining my battery like a mother!!! I literally watched it go down by 10% in minutes. Anyone else experienced this? How do I find out which app is the cause of this without having to uninstall each app?
Sent from my SAMSUNG-SGH-I897 using XDA App

download OS monitor or system panel and see which apps are consuming or hogging cpu

I did that and nothing looks out of the ordinary. I'm so frustrated!!! Could it be the rom or is it an app?

No help here...........I got tired of the battery drain from all the custom ROM's I tried (just about all of them) and am now back to JH7, getting almost 32 hours before being drained. I have done some tweaking to it, got the GPS working great and everything works whereas with some of the ROM's something had to be sacrificed.
Here are some screenshots:

In the last screenshot it shows 30 seconds to lock, all day today I was around 10 seconds to lock and 10 satellites.

Did you flash with 100% battery and then calibrate your battery afterward?

No it wasn't at 100%... And no I didn't calibrate the battery... Was I supposed to??

It's certainly worth a shot. I had the same thing happen to me once a while ago and it seriously extended my battery. There's some threads here that describe the process which essentially involves discharging and charging your phone off and on and deleting the battery stats through CWM.
I always flash a ROM with a battery showing 100% and I typically net pretty good battery life doing it this way.

Always recommended to do so whenever you flash...........YMMV

Here's a great thread for you to look at.

So can I just calibrate it now or do I have to reflash my phone?

You can calibrate at any time. No need to reflash.

Maybe before you reflash, please wipe of the factory settings and partition and also the Dalvik cache and battery stats in "Advanced" settings using your Clockwork.

Ok I'm trying one of those recalibrating methods. Maybe I really should've read everything before I flashed... but there was sooooooo many stuff to read and watch...
When you say "advanced" in clockwork, thats the rom manager correct? when i look through it it says advanced mode for premium users only... is that the right app?

I'm sorry but now that I search through the forum I see that its a common problem and it's something I missed. I'm totally new to android (smartphones period) phones and flashing and stuff. Thanks for all the helpful tips!

One question though. When you delete the batterystats.bin file, does it get recreated at a later point or never again?

It gets recreated, yes.

Have to remember as well that each user may see different results with the same Rom. Kernels. Modems, Roms perform differently from one device to another based on a multitude of factors. After you have done the basic steps to try to stabilize battery drain, I would then begin by experimenting with different kernels and modems.
Idle drain is the test I normally use after ensuring proper battery readings, sensor usage and app CPU behavior. Many times simply flashing to another kernel shows immediate results.

I've yet to learn about flashing kernels. I'm now running perception 10.2
Sent from my SGH-I897 using XDA App

Download the sgs kernel flasher app from market. Go to kernel thread off your choice in captivate development an download kernel, placing the file on your internal sd card. Run the app which is poetry self explanatory.

Definitely try a different kernal or modem. Generally, you can find feedback in the rom thread about what kernal or modem gives the best battery life.
I haven't used Assonance but I had to flash the firebird 2 kernal to get good battery life with Perception 10.2. Keep trying.

I was having issues until I did the following......(and I am on the same build as you)
Go into recovery and wipe the dalvik cache. Reboot.
Set the automatic screen tweak under CM settings/user interface
These two things have seemed to make a pretty big difference. I am not running any tweaks or anything and with moderate use (some wifi, 10-15 emails, 4-5 texts, gmail sync) I am at 89% after three hours off the charger. While this isn't great (IMO) it is lots better than I have been getting. Hope that helps.
I had the same issue, but with only 3 hours of life between full charges, and one phone call for 15 mins.
I reverted back to 8/24.
Smolck you mean the automatic back light right?
I wiped kalvic cache... ill see how it goes without batt tweak and no apps running.

Yea. I just set it to what I thought were "power saving" settings. It seems the Dalvik cache is what did the main thing to help. All I can say is that I am still over 80% and I have been off charge since 7:00am CST. And this 8/25 build is SMOKING fast on my phone
It is fast. Its even faster with launcher pro.
Are you using the batt tweak? Which kernel?
Down from 55% to 50% in 75min

That screenshot isn't enough info. But go to settings/about phone/battery use and you will get a better idea of what is using the most power.
From 100 to 90% in 2 1/2 hours now. That's pretty good right? Stock 8/25 kernel w no tweak. If it keeps working ill backup and add other stuff and see

Well I think its fixed. Managed 13 hours and still 35% left using Google maps and Pandora plus regular use. Running the same configuration.

Try to completely empty the battery by rebooting after your phone shuts down because of low battery. Keep rebooting it after it shuts down again till it doesn't want to boot anymore. Till the battery is completely empty.
Then Charge it again and leave it on the charger for more then 20 hours.
Don't know if it's gonna work but give it a try
EDIT: Q? are you using a custom ROM ??
Ok I'll give it a try, thank you. I have this problem since i flashed a modaco firmware and wiped my battery cache via cwm. Anyone else having those issues?

48hours when you are using him or 48h max on standby
USE phone heavily. Use it till the system turns OFF automatically
Turn OFF phone
Charge till it says it is FULL
Start phone in RECOVERY Mode
Select Advanced CWM Features
Select Wipe Battery Stats
RESTART phone

Sorry, should have given more detail. That 48 hours is with general browsing and social networking with a fair bit of video recording and camera use. No 3G though. All data was over WiFi.
Certainly not just stand-by though.

No full power use of the processor i understand
i thought i had the problem too with the MDC fear 5.3 but it just jumped from 98% to 100 after 10 minutes so its probably a mistake which solved itselve if you charge it long enough.

Didn't work for me, i did it exactly this way, charged it for about 10 hours, booted in recovery, wiped the battery stats and it stills shows 97% when i boot it. However, it's not a disastrous failure, i can live with it and hopefully it gets fixed sometime.
Finally, i found the solution for me. After i reflashed the stock rom, where this problem doesn't occur, i flashed a modaco rom again WITHOUT WIPING THE BATTERY STATS. Now it's all working fine, i charged my phone to 100% a few minutes ago. Hope it will help some of the people, who are still having problems.
Does kernel version has anything to do with this issue?
Don't think so, i tried the stock, Paul's kernel from FR12 and the EternityProject Kernels 1.3 and 1.4, it was all the same until i tried reflashing without wiping battery stats. For the record, i flashed the new TK-Rom V 0.6 with the EternityProject Kernel 1.4.

Battery drain xxjvp

Anyone know why Google Services has such high usage percentage in battery use(almost 50%)? A solution maybe?
Sent from my GT-I9000 using XDA App
I'm on jvp and have got no drain problems yet. Does it go away after a reboot?
Sent from my GT-I9000 using XDA App
no it doesn't. It shows that Google Services is running,and the processes are Network Location and Google framework.. I can't unninstall the framework,because i can't use the market after.
If a simple reboot doesn't fix it then if you wanted yo you could do a factory reset using this code *2767*3855# in phone dialer. This will delete everything on the phone and reinstall the firmware. But it will delete everything! Also any lagfixes should be reverted back to rfs before using this code.
There maybe another fix but that's all I can suggest for now.
Sent from my GT-I9000 using XDA App
Did you just flash the rom? It is expected that Google Services will consume an unusually high battery after flashing. It is because google account has to sync data from phone to its servers and vice versa. Let it run for a few hours or until the initial battery runs out. After that I think your rom's battery usage will "settle down".
Battery drain seems to be fixed with 2.3.4 for me.

[Q]Android-system 29% of Battery JVQ

Hi,
I recently updated my phone to JVQ but now i'm having a battery drain. The cause (i think) is the high percentage of the android-system. By now its 29% and that's alot. I already deleted the programe software-updater so that can't be the trouble maker anymore. Does someone has a fix for this?
Greetings

Yeah....let your battery go completely dead, then try turning on to make sure its dead
Leave your phone off and then plug in charger until its full, then unplug and plug in again to make sure its full
Repeat these steps 2-3 times and it should be all fixed for you
Also....using titanium backup, freeze the program called "Samsung account" that's another culprit in the "battery drain crisis"

Try going back to stock froyo, and flashing cfroot kernel so your phone is rooted but not deodexed or any other mods, then repeat the cycle and see if it gets better that way.

[Q] THE SOLUTION to poor battery life

This is getting really annoying... battery gets charged to 100%, drops slowly then after <50% the phone starts to get hot and just start dying rather quick. I have changed batteries, actually bought a new one - still having the prob. I think i know the culprit but not sure how to attack it. Unfortunately because of my post count, i can't upload a link to the screenshot
!!! HELP !!! :crying:
Well...tell us what u think the culprit is, plz.
And more info from ya would help.
What Rom are u running, Overclocking, Undervolting, etc. Thx.

I'm running ParanoidAndroid v.2.50 | Devil Kernel 3.0.31 | Modem I9000ZSJPG (which is rumored to give excellent battery life)
No overclocking or undervolting - don't really mess with those things.
Anyway, when i check battery usage "Media" always use the most when i notice the phone start loosing battery life n running hot. There is a time when i saw Media at 88% while everything incl. screen was less than 20%.
...maybe a rogue app or something syncing constantly ??

You probably have com.Android.Media process running all the time..
I had the same with all recent kernels until I have reformatted my both SD cards internal and external.
Media scanner should be out of running processes after five minutes after boot.
I check them via terminal from :
top -m 10
command
Or
busybox top
In five minutes after boot I have almost zero CPU usage from top statistics
Hope it could help you
