Is there a lagfix that doesn't drain the battery??

Hi guys, now that there are SO many great lagfixes around, I have tried a lot of them, and they all seem to drain the battery down quite quickly.
Is there a general consensus on one that doesn't drain the battery?
Running Darky's 2.2 by the way.
Thanks,
Mal

Ext4 drains more battery. Voodoo is usable, but having all partitions on ext4 (using the Universal lagfix kernel) halves the battery life for me. I am right now on stock partitions (RFS everywhere) on JP6 and is really smooth and lagfree.
I think that sammy has made some pretty good improvements on their latest ROMS. The only thing that still sucks is the browser.

I've found Voodoo 5 Pre6 has excellent battery life.

I'm using OCLF on 2.1 and I don't see any difference in battery drain.
Maybe its the 2.2 Roms that use more battery (JIT)?

Its all matter of bad flashing!
U can get excellent battery life by pulling the USB cable in the right moment.

without using my phone I bet it can stay alive for over a week, using the jpk(wont dare upgrading further since i'm happy) in combination with the OCLF 2.1

Awful Awful battery life since Darky's ROM

I have always had stock ROMS with my i9000, ending with JS7. I read the battery problems people had and I always counted myself very lucky that my phone had a pretty decent battery life.
Daily I would SMS (a lot), the odd phone call, quick blip on the internet (3g), lots of angry birds and doodle jump! I would get at least a couple of days before it went into the red.
Then I made the big mistake of installing Darky's ROM, it looks nice and feels a bit snappier, but now the battery is in the red in the evening after a full nights charge. This is even after severely curbing my phone use to try and extend the life. I have tried all the wiping tips and tricks too.
Same apps, different ROM. Darky's is an absolute nightmare for me and I will be going back to stock.
So is the ROM just another variable in the mix of battery issues, or the main offender?

Hello. I've the same battery drain, and I think it's very annoying when at evening you need to charge it again without using strongly the phone. Otherwise the Darky's rom, (I'm on 9.3) is very nice and marvellous, but this battery drain issue makes it worse.

Have you tried using spare parts to see which app is sucking baster or cpu? Did you download the rom configure tool from the market? Which gallery did you instal worth the rom?

This and:
have you let the phone drop below 10-5%?
Flashing screws up the battery indicator (how much depends) and it calibrates itself while in use. Letting the battery fall, or even the phone shut down by itself can speed up the process quite a bit. This helps only if there is no battery hungry app that's eating all your powrz though.

I haven't tried to see if there is an app sucking the life out of it because I never had any issues under the 3 or 4 stock roms and I haven't d/l any other apps. The battery deterioration started instantly I flashed with Darky's. I don't know which gallery it is, it came with the d/l. What ever it is, it doesn't work! No, didn't use the configuration tool.
I must admit I haven't let it run under 10% as I want my phone with me working. But wouldn't this manifest itself when I updated the stock firmwares?

ok mate, firstly search the market for the Darky Rom Configurator, shoudl be easy to find, you shoudl be able to reflash without wiping all your apps, run the config app first and pay special attn to the 'Lockscreen wallpaper' of the tool, there aint many options to choose. Got the gallery drain bit mixed up, sorry tired
If i was on my own PC id give a bit more detail but its pretty straight forward.
Im running 9.3 and get a full days mid-heavy use, i normally go to bed at 10-15% which is fine with me

cheers for the advice mate, I've just grabbed the app so I will do the flash in the morning.
I will report back my findings!

Just a thought but Darky's Rom uses JS5 and wondering if has something to do with the modem? Just a theory but wondering if you could replace back to JS7 and see if that helps. Just a thought. I'm used to a day's worth of battery myself these days.

The faster you make the phone go the more power you use darkest Rom are ok but messed with too much

I got really bad battery life for the first few weeks using darky. But now the battery life seems to be longer and more stable and average. I did do calibrations a few times tho.

You won't get better battery with Darky ever.
I played around quite a lot, 9.2, 9.3, calibration, fresh system, darky rom configurator, different kernels, lagfixes, no matter what, my battery drain was mad. It's a quick and smooth rom, but that's the downside of it.
I switched back to Doc's rom via kithen with same kernel, and quess what? No calibration, no playing around, nothing special I did and battery life is brilliant! Of course it lags here and there, that's Doc's drawback(no lagfix applied tho)

You will often find that if you flash a number of roms you get battery drain . Apart from the actual rom itself you need to flash to a clean firmware reset battery stats use a suitable modem charge battery once using bump charge method then wait a few weeks for it to settle down .
I am using rom kitchin since Darkys killed my battery life months ago .
JPY and JPY modem no complaints about excess battery life .
But i did flash back to clean stock before custom rom and wipe everything .

but this is true even if i use a kernel mod.. instead of a full flash? i think that a stock rom with custom kernel made for battery lasting is better... or not?

Have u all tried Battery Bump Charging?
Hi, I am not a Galaxy S owner but I am doing a research on this issue for a friend.
I am a Milestone user and I am a ROM slut (I flash many ROMs back and forth)
So I am very familiar with cases where after flashing a new ROM, your 100% fully charged phone is actually 60%/
Here is a posting on a few ways you can do a battery bump charge. When you perform this battery bump charging technique, u will be surprised to see that your 100% fully charged battery is actually not 100%

New custom rom on my I9000

Hello everbody,
I want install a new custom rom on my device with low battery drain. I now have F1 Innovation V13 and when I do something the battery is in a few hours empty.
Which other custom rom can I use with low battery drain and 14 toggle.
Thanks in advance!
Greetz,

It all comes down to what are you doing on your phone. If for example you're using it intensely to play games, the battery will discharge in few hours. Wifi and 3G enabled also drain battery. But if your battery drops down to zero after few hours of low-medium use there's definitely something wrong. Best battery life can be observed on stock software. I recommend flashing base JVT, then rooting the phone with chainfire's CF-root kernel (it's as close to stock as it gets) and after that installing stock+ add-on by $omator (everything you need to make your phonerun without FC, be rock stable and smooth as butter) .

1 to 1.5 day of battery life with 3g turned on depending of phone usage. Remember to always calibrate your battery after changing the rom. Unfortunately almost every smartphone has poor battery life and SGS is among them. If 3g and sync isn't important try switching those off, and turn them on only if need be. Also set your screen to automatic brightness, because the display at high brightness drains A LOT of your battery.

Hello
How do I calibrate the battery?
Sent from my GT-I9000 using Tapatalk

Get callibrating app from the market easy peasy

Darky's is a good option. I did use it for a long time. Always about 10 till 14 hours depending on the usage.
Now for a week i am using mintberry. It seems i get a better batterylife with this rom. But than again it all had to do with how much u use youre smartphone. In my opinion people who say it last for days don't use their phone

I also agree that Darky's has pretty good battery life. A lot of people complain about CM7's battery life but in my experience it wasn't so bad either.

Im on Galaxy Droid and it looks really nice battery life is really good and the theme is SO NICE

Im getting good battery life and stability in Darkys 10.2.2
Steps
1. Backup your data from internal SDCARD and then format it.
2. Make sure that your SGS is 100% charged (make sure after removing the power connection)
3. Flash your SGS with Darkys 10.2 RE
4. After rebooting copy 10.2.2 zip file into SDCARD
5. Charge you SGS 100%
6. Boot into recovery.
7. Wipe (Data/Factory Reset, cahe, dalvik cache)
8. Install Darky 10.2.2
11. Enjoy!!!
* Dont try to restore the backup Apps. Better to do fresh installation.
* You can install Darky10.2.2 either one of the method CWM Recovery or Darky ROM tool or Darky OTA

Battery Level Not Reading Correctly...

Having some strange battery issues....
My battery was at 24%.. I plugged it in to charge and left if for an hour and it would not move past 24%. Unplugged it, plugged it back in, left it... same 24%.
I gave the phone a restart, and when it booted, it now read 65%.
Last week, I had been noticing bad battery life, so I did the battery calibration talked about here ( http://forum.xda-developers.com/showpost.php?p=23203126&postcount=9 ) and then cleared my battery stats...
Battery life definatly improved, but, now I had this issue today.
Any idea what could be causing it?
Oh yeah:
Rooted Phone, running Myn's Warm TwoPointTwo RLS 5. Kernel: 2.6.32.17 [email protected] #2

I'm glad to hear calibrating your battery yielded improved battery life for you. I've experienced the same thing in the past with other ROMs, but I haven't while using my current ROM (Nitrous ROM). I may be mistaken in assuming it's because of some setting in the ROM, but it's just something I noticed. Or possibly it's because I'm using the stock kernel with this ROM? I'd be interested in hearing if anyone definitively knows what causes the battery misreadings too.

I read somewhere in the forums(cant remember where exactly) that when flashing roms, its a good idea to re-calibrate your battery after every flash....I've been doing that since I read it and seems to work as far as I can tell

Your battery could be going bad, but if its just a reading error, then it could just be the ROM you are running.

You are correct it was found by members of googles development team to be unnecessary and could possibly do more harm than good in terms of the phone using the battery properly, newer phones like the et4g come stock with trickle charge kernels(read SBC) to try and discourage ppl from wiping them by giving them a more accurate reading in the 90-100 range

I always try to calibrate battery (on full charge) after flashing a new rom. Search the market, Battery Calibration is free.

So, to rule out the phone itself/rom/etc I swapped batteries with the wife for a couple days. She has the same phone, same ROM, Same Kernel, same everything...
Anyways, long story short, the battery acts the same way in her phone as it did in mine, while her battery works perfect in my phone just as it did in hers.
So the battery is definatly toast... I've already got a brand new OEM battery on its way to me...
Figured i'd come give an update. Thanks all!
(Oh yeah, to vel7wil and the others, I DID recalibrate the battery, as I mentioned in my initial post. So, be it unneccessary or not, it didnt help me any in this case lol!)

Battery drain

Hello!
I rooted my phone as of yesterday, I charged it all night and when I took it off today the battery went from completely full to dead withint 3 hours of no use. I did not use the phone at all.
Any ideas?

If you just rooted your phone, you should not have battery drain... Try to temporarily disable root (with Voodo OTA RootKeeper for exemple)

Use better battery stats to nail down which app is causing the drain

Did you try wiping your battery stats in CWM - advanced?
There's also an app, Battery Calibration, on the Play Store that may help with that.
Not uncommon to get weird battery readings after changing rom's or rooting.

This is soooo strange. Not a normal behavior!! Before you root your phone, how the battery lifes goes??? Are you in a stock or modified ROM? Wich kernel are you using?
I faced this issue a couple weeks ago. Android S.O was the culprit and it was driving me crazy. I was using a custom ROM (RemICS-UX). I solved the problem returning to stock and erasing everything, then i reflashed the ROM and the kernel, in my case Devil3 0.79. If you want to give it a try!!
After that my batterys life is pretty fine, during at least 2 days!
Feel free to ask anything you want! Cheers mate

Go through a couple more full charge cycles, if android os usage isn't very high then, it should be fine.
Edit: on second thought, draining the battery without use in 3 hours is extreme, and would suggest that the CPU is running at max speed all the time. If it doesn't solve itself or improve a lot after a few more charge cycles, reflash everything.
Using GT-I9000 my sent Tapatalk 2 from.

Did you just root your phone or did you flash another ROM? Some ROMs have horrible battery life.

The stock battery usage monitor (Settings>Battery) should be enough to tell you what ate your battery. If it's a particular app you're running, try disabling that and see if it improves. If the usage is mostly "Android System", "Mobile standby", or something like that, then you have a tougher problem. The free app CPU spy will let you know if something is keeping your CPU usage high. Better battery stats is pretty cheap and will give you much more specific information.

+1s for BetterBatteryStats and waiting a few charge cycles before judging/debugging your battery drain, especially if you changed your kernel to root or flashed a rom.
I find that after flashing a new rom or kernel my phone, the battery level shown in recovery mode is higher than in the rom's settings, for a couple days. (You can see batt level in semaphore's recovery). I once dud a lazy search about this and found nothing, but I figure that's what is meant about waiting a few cycles gir your battery to calibrate.

There's no such thing as "calibrating your battery". It's a myth. Wiping your battery stats file doesn't do anything other than reset the tracking of what's using power. It doesn't magically fix your battery meter. Flashing a new ROM doesn't leave left over data, again a myth.
Battery life is never consistent after flashing because your ROM needs to "settle" for a day or two first and during that time your ram and cpu usage are all over the place.
The rest is a placebo effect.

I think I may know what is happening to you as of now. Try to bring up the Battery settings if you are on ICS and take a screenshot and post it here. If my 'spider' senses are correct, your phone did not go to 'sleep' and remained awake.

Currently I'm experiencing a huge battery drain too. I used both tools which where mentioned here in this thread and when the drain occours, CPU spy reports that my SGS didnt go in deep sleep at all with turned off display, it was at least at 100mhz all the time! I attached 2 logs from better battery stats and it seems like the NotificationService is causing it?
I'm using JW6 PDA JW4 Modem and JVC CSC in combination with the MNGB 0.5.8 Kernel.

Definitely, now you got to find out what is causing it!
