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.
Hello i have searched everywhere and could not find an answer for my question.
I have Galaxy S I9000 16GB with Darkys Latest Rom 9.1 Froyo 2.2.1
My battery does not last a day with normal use of the phone.I have tried every setting that people have suggested(wifi off,data network off..haptic feedback off,screen power saver on...charging until full turned off and using it till phone shuts down and then recharging to full level..)I have found that in Battery usage details Display uses 75% and even when adjusting display settings to lowest 11%Brightness or automatic brightness it does not fall under 75% i saw someone had 45% Display usage in battery info..
Could someone please give me any ideas what to do?Phone is 2 months old its brand new..
the only way to get a low battery usage % is by making other stuff consume a lot of power. that of course doesn't help battery lifetime
Try another rom .
Did you have same battery life on stock rom when new .

Update
Hi guys just to let everyone know battery life has improved dramatically after installing darkys latest rom (9.2 extreme edition) Love it.Battery lasts Almost 3 days with normal usage!!Am VERY Happy!!
Yea, so iam looking for a ROM which has the best battery life!
My uses:
Wifi
Half an hour of app usage(excluding messaging and calling)
constant messaging
slight OC, 710 Mhz
3 to 4 hours of calls each day!
Iam currently on the Hybrid V.5 Rom, and although the battery life has improved since V.4! but iam still looking for Senseless or sense ROM with speed, stability and a great battery life!
Just SetCPU itself can achieve this. Create a profile with low max speed (352) and min speed (245) when the Screen is off. You will notice a dramatic increase in battery life. Lastly, 710 MHz is not a "slight" OC by any means.
Although, with your usage pattern, it seems you are a pretty heavy user, so, I doubt you will see too much of a potential change with this. For the record, after I created the SetCPU Profile, battery life has gone up for me from about 1.5 days to more than 2 days now (Sometimes 3- 3.5 days with light usage), and, the scenario was similar on both, WildPuzzle 2.2.1 and CM7. (It is better though with CM7, so I am assuming AOSP ROMs are better battery managers than Sense ROMs)
CM7 for is best for battery life. But i didnt try all roms, but much.
I'd have to recommend CM7 Nightlies.
It's just so good.
For example:
Battery is fully charged at midnight, went to sleep while listening to songs and when I woke up the next morning it's still at 100%. I also do constant messaging. Other than that, I'm on WiFi and have set the phone to run in 2G mode only.

dont mind but this seems absurd must be something wrong try to boot into recovery and clear battery stats before you put it to charging next time..

agree with you
Definitly CM7 it's far the best for battery saver, cause Gingerbread was created also for that pourpose.
Hey guys,
I'm experiencing rapid battery discharge while Nook Color is in standby mode, battery life used to be great while on standby but after using CM7 on sdcard it's nearly discharges like when it's fully working...
Any ideas?
Thanks in advance!
sounds like your battery maybe on its death throws.. or perhaps you have too many background processes suckin up juice.. we need more info to be helpful
Reboot without card in and check stock performance. They shouldn't affect each other. Plus CM should have better battery life very soon.
Are you running the performance governor? this would keep your CPU at max ALL the time. if you are try switching to Interactive.
Does anybody know how the batter performance in standby mode for CM7.0.2 compares with stock?
Could you tell me when when the CM7 battery tweaks are coming?
Also, could somebody tell me how to maximize battery time when using Nook?
Lots of questions! Thanks in advance.
I was on cm7 but the battery drain was an issue for me. There is no fix currently but the awesome folks at the cm7 team are supposedly going to iron this out soon. Stock should last at least twice as long on standby.
If you use the nook mostly at home I would lower the display brightness all the way down, and completely shutdown at night.
Assuming not overclocked, in use CM7 is very similar to the stock ROM because the screen and backlight are taking most of the power.
In standby the stock ROM is around .2%/hr with wifi off. CM7 is around 1%/hr with wifi off.
I have CM7 nightly build 55 on my Nook and the battery life is amazing.
Besides the feedback others suggested, check to see if you have things actively running in the background. Is the setting to keep Wifi on in standby turned on? That could do it. Do you have some funky mail client on their set to check every 5 minutes or something?
I think the best suggestion was the one previously about taking the SD card out and run it as stock to see how the battery life compares. If it is fine with stock, then you know something goofy is going on with your CM7 install and I would just start over on that with the newest nightly, etc.
My batt stats say Phone idle and Cell Standby are 22% and 17 % over a 12 hr period. So those are what are killing me and the NC isn't even a phone.

No, they are doing nothing. Move along.

Battery performance even on overclocked nootered 1.2 Nook Color is great. I am getting drain of less than 0.2% compare to closer to 2% on cm7.
This is due to cm7 not having full sleep.

Thanks for your reply Canadoc!
Do you know how Stock 1.2 ROM's battery performance compares to that of Nook Froyo 0.6.8 R7 ROM?

As what the title says.
SGS has a good performance, but uses really a lot battery in every ROM.
Which one uses the least?
Stock ROM.
there are millions of threads out there explaining battery life and which ROM has best battery life.
is there really any need for another pointless thread ??
battery will get worse if you leave stock ROM, it might change a lot or a little, so if battery life is important to you, stay on a stock ROM
Oh I am sorry.
I find lots of threads about battery life but I didn't find any about which ROM has the best battery life.
And I assumed that there will be some tweaks to have better battery life.
there are many tweaks, including finding the right kernel and undervolting it.
avoid using task killers- they do more harm than good.
stay away from CM7 - MIUI these have battery drain bugs
the list is endless, i would recommend making your own rom at www.romkitchen.org
only cook stuff into the rom that you will use, there are many roms out there packed full of **** we dont use, thus leading to battery drain.
just be wise when choosing
out of old experiences
best i tried was a combo of rom and kernal
insanity rom with a laststufo kernal
of course it isn't the latest version of either but i remember it gave me a big batt diff
usually lasted from 6am to 1pm afternoon before the batt ran out
but with that combo it lasted a full day 6am to 10pm and had about 40% left
also optimized with tasker to watch net usage with screen off and a net check every 10 mins for email notification
found out default email app was bugged so forwarded all my hotmail emails to gmail and that fixed that
now after getting me a lot o spare batteries hell i run thru 3-4 batts a day with everything on and i mean everything with OC as well , hell lot of msn, twitter, facebook, games, browsing im all fun now woohooo ^_^ TY Chinese wall battery chargers ^_^
I use Gemini App Manager to control which app that runs during startup and that helps tremendously to battery life. Juice Defender helps too if you have 3G on. This way you can use any ROM you like and not get too much battery life difference.
I also feel that Gingerbread in general seems to improve on battery life, but I was only on Froyo for 2 days since getting the phone so not a very wide assessment
