[Question]Display drains Battery after flashing XXJPK for days

Hi experts here,
I am new i9000 user coming from G2.
I flashed XXJPK for days, found that my battery drops very fast.
I stop all data access at night and the battery still drops...
I found that the 'Display' uses > 80% !! (even when I slept for 8 hours)
Attached is the screen cap of my battery stats..
Do anyone has the same issue?

This is Android Development, not Questions & Answers! Please post in the right sections!

What have you installed after JPK? Task killer? Lag fix?
Mine is not doing that. I did a hard-reset yesterday, installed my apps (no task killer, no root, no lag fix) and disabled everything (WiFi, bluetooth, GPS, 3G, autosync). Battery did not drop even 1% in 6 hours.
Display should not take any battery if it's off. Maybe you have something that awakes the phone constantly. Check autorefresh on weather, e-mail, twitter, news feeds... I usally have that disabled or set to 8 hours minimum.

got the same problem here.. i do got the docrom (custom rom) ,auto killer installed and lagfix (OCLF v2+) it goes from 100% to about 60% in 9 houres.. without doing a thing.. on top of that i got juicedefender ultimate installed.. but it doesnt seem to help at all..

The problem is why the 'Display' uses > 80% while I off the screen for hours?

Got the same problem here. I just reverted back to jm8 (eclair 2.1) with takayuma Rom.. I think all froyo versions have battery draining issue

I think, you guys must make this and maybe fix battery issue:
Refreshing battery stats after Odin or flashing (important)
or me personal, for my Galaxy very helpfull was this HTC Desire methode:

I'm having exactly same problem with you. My brightness is 75% even in sleep mode and it drains the battery. I guess thats the main culprit to solve my battery draining issue. I wonder why it happens to certain people, because some users only have 48% for brightness and their battery can last more than a day
** apparently using Eclair 2.1 doesn't solve the issue as my brightness is still 70% ... I've tried the batterystats.bin fix and same thing happens. Damn !

It's true. JM8 and the battery fix doesn't help.
But I found that when I turn my connection from 3G mode to Wifi mode, my battery drops only 10% overnight.
I think there is some problem in the 3G connection.
Do you think this is kernel related?

One way to keep the drain down is getting a black theme such as the Transparent theme and setting a black background. Because of the AMOLED screen black is basically 'pixel off'. It helps just a bit.
I have similar experiences with WiFi vs. 3G, 3G drains battery awfully fast whereas WiFi seems to be consuming significantly less power.

battery down from 100-96

HI, i have upgrade to darky's v8.0 ginger bread edition...
my battery dains quickly.. when my battery was fully charged i removed it then my battery became 99% suddenly..after few minutes it became 96%...
battery doesnt even last a day somebody help me
my
firmware version-2.3.1
baseband version-I9000XXJPY
kernel version- 2.6.32.9 [email protected] #8
hope you guys help me!!!

most likely just the rom, try to keep wifi bluetooth and gps off when not using it, and set screen to auto adjust. Not much you can really do, sum roms have good battery life and sum is jus flat out poopy

which rom are you using? do u know any ways to improve battery life... how is ur battery working.. how long does your battery lasts?

That is strange. I have Darky's V8 ROM and the battery lasts me all day with about 60% left. I charge it every night so it never runs out of battery.

do you know any method to improve battery life?

[Q] ROM with best battery life

I'm searching for custom ROM that has at least a decent battery life.
I'm on Darky's v10.1, but I'm getting Android OS bug very often (and then battery lasts for 5-6 hours), and when I'm not, battery life is around 10-12 hours. I'm pretty annoyed that my battery can't last for whole day and I'm looking for ROM that will give me at least 16 hours of battery life. Also it's preffered that ROM is pretty fast too. Thank you

Try XWJSD, the latest 2.2.1 firmware. Batery life is prety good and it is the fastest froyo so far. On my phone about 35 hours on normal usage..

Oh, I would like to have Gingerbread firmware, I don't feel like degrading my phone back to froyo :/

That's strange cos I'm on Darky's v10.1 and it's the best I've found so far. Battery is lasting me about 16 hrs on average, depending on what I use it for. Day to day use of calls, lots of texts, some internet and some pics can see 16hrs.
There is always this option: http://cgi.ebay.co.uk/1930mAh-REPLACEMENT-BATTERY-SAMSUNG-I9000-GALAXY-S-/250807245269?pt=LH_DefaultDomain_3&hash=item3a6546d9d5

Well, I guess it depends on what you use it for - but it's not enough for me. And I heard this battery isn't making much difference...

Ok, thanks for letting me know about the battery replacement. I was considering one of them for myself

Hey, unsure if this will interest you or not, but I use Juice Defender ultimate and it is absolutely amazing!
Depending on your usage (much of the time my phone is idling) and whatever settings you set, this app will make your battery last a very long time.
I've just check my phone's battery usage and after 15 hours I'm still on 78% battery.
Obviously these figures would change dramatically with more usage but just thought there wasn't any harm in letting you know about it if you didn't already know. 8)
PS: I'm using Darky's ROM v10.1.

I have the following ROM and battery consumption is very low. Try it and comment.
PDA: I9000XWJVH
Phone: I9000BUJV3 from BUJV9.
CSC: I9000OXAJVK
KERNEL :Voodoo test 6.0 de supercurio.
If you prefer, you can change the CSC file for another.
Greetings.

juwe's rom,always wifi on, with aggressive use more than 1 day,
moderate use 2 days
only calls and sms more than 2 and a half day!

try "Advance task killer" app
keep it to stop all program when screen off
and you will see the battery, better than before

I need a ROM :S

Hello everybody,
and first of all SORRY FOR MY BAD ENGLISH !!!
I have my Galaxy S now since 10 Months and i try over 10 ROMs but
I didn´t find a ROM with a good battery life...
I really need help
Which ROM has the best battery life ?
What can I do for a better battery life ?
10 minutes ago i was with Wlan in the Market, and after 10mins my
battery lost 6%.. Is that normal ?

The Battery lost of 6% in 10min, is pretty normal, because the WLAN need very much of the battery life.
I tested many rom's and in my opinion has the Darky's Rom & cm7 a very good Batterylife.

The modem controls the battery drainage, signal etc..not the ROM! Flash a rom you enjoy then CWM a solid modem that hooks up with your area!

6% is a little bit too much. I suggest you to check "battery use" in about to see who consume battery the most. For me, it is "Display". And just as graw91 said, WLAN uses battery a lot.

To control brightness of the display is the Screen filter app very good.

[Q] Bad battery drain, new SGS, tried everything

hello,
i've had my SGS for a little over a week now. from day one i noticed battery drain but i thought it was normal for a new device. i flashed darky's 10.1 extreme on the second day i got it because it was very slow and had a lot of bloatware ( i wasnt very patient and i flashed at 95% or 96% battery), the drain was still there. i let it go through a few recharge discharge cycles and no improvement, so i used an app from the market called "batterycalibration" by marosige, no improvement and it the reading would drop to 99% or 98% after taking it off the charger.
i did a little digging and discovered i had the android os bug (was over 50% usage usually) so i used titanium to wipe software update and samsung account, and froze the first, didnt help by much
i then flashed darky's again at 100%, and now it still reads full charge after removing charger and android os bug i gone (reads 4% system and 4% os), but drain was still there. i emptied it to the point it couldnt turn on anymore then charged it from wall charger while turned off to 100% while i slept
i woke up and tested it by playing a game (Blastmonkeys) for like 20 mins and the battery went down to 90%, that was less than 2 hours ago, and now its at 87% and it was completely idle
notes:
my brightness is turned all the way down with no animations but display reads 54%, wifi is usually on when im home but battery stats show 6% wifi so i dont think its a big problem
also, the device was bought locked in france by someone else and im in egypt, so i dont know anything about warranty..
im sorry for the long post but i tried to be as detailed as possible...

hello,when i upgraded my sgs to 2.3.3 i also got battery drain and android os was consuming hell lot of cpu about 70%,..,.,then i flashed 2.3.4 jvp i didnt get any battery drain in that firmware then i upgraded it to 2.3.4 jvq this also donot have ny battery drain..,,.i recommend u to flash it and try it once

see jvp and jvq are bug fixing firmwares and i didnt use any custom rom ,..,i have stock firmware which i just rooted and didnt use any mod or rom.,,.,.jvp and jvq are stable roms diffrence between the both is that in jvq browser is improved gallery improvement,.,..,etc

As far as I know, the percentage not being 100% after unplugging is normal. To prevent wear on the battery, the phone cuts the charger after reaching 100%, and restarts charging when it reaches ~95%.
I don't think a 3% drop in battery over 2 hours is uncommon. Wifi and data connection will pull a lot of power if on, even in standby.

Normal, this phone drains about 20% battery per hour of screen use, slightly less when watching video.
2-3% drain over 2 hours is also pretty normal if you have wifi/sync on.

I just got my SIM card replaced today. The one I had used before was about 12 years old. So whenever you-re having battery issues, make sure your SIM card is not the cause for it .
