To drain the battery, I usually turn on Bluetooth, Wifi, GPS, all the good stuff. Then I downloaded this one Flashlight app from the Market which essentially displays one color full screen, default white. Crank up the brightness and run that app on white and it'll really put the hurt on your battery.

Edit: Today I learned that this may be potentially harmful information. Will someone give a good scientific explanation why though? I'm curious to learn more about batteries. However, this is how I've been draining my battery and it is a damn good method if that's what you want done.
[Vibrant General] regP:
Mine says 2.6.32.9 no matter what kernel i flash. Try flashing it just to be sure. I've tried all the ROMs and they all drain hard until I add the stock kernel to them. Though now a days a lot of ROMs include the stock kernel (Macnut and Axura for sure do). The problem with all the custom kernels is they dont seem to let the phone sleep so when your screen turns off the phone keeps draining as if you were using it. Stock fixes this so when your screen turns off barely any power is used. I

But like I said.. reflash it just to be sure.
[Vibrant General] EvilPickle:
You happen to have a link to the stock kernel??
[Vibrant General] regP:
Taken from Eugene's site.
[Vibrant General] iynfynity:
to the OP, try axura rom. i have tried all the TW, eugene and axura. axuras the only one who gives me a good batt life
[Vibrant General] regP:
Thats because Axura uses the stock kernel ;)
[Vibrant General] gongonzabarfarbin:
Android is based on Linux and uses the Linux kernel as a base. The Linux kernel your phone's kernel is based off of is version 2.6.32.9
[Vibrant General] EvilPickle:
ok.. think I loaded the stock kernel up.. lol I'll let it run for about an hour and see what kind of CPU numbers I get in idle.

Thanks again for everyones help/input.

FYI.. just put it in flight mode for a bit and CPU usage dropped down to almost 0%.. I'm not understanding why it cant do that when the phone is idle.. ahh well.
[Vibrant General] regP:
Idle for an hour should lose no more than 1% battery depending on how much stuff you have polling and updating.
[Vibrant General] Master™:
No it doesn't.

That is just the version.

That version won't change like the baseband does.
[Vibrant General] regP:
My bad, I recall you saying 2.1 used the stock kernel on your board.
[Vibrant General] iynfynity:
lol i remember when i was using axura 2.03. i only lose 1% overnight with edge only and the background data ofd.
[Vibrant General] Molezou:
Best battery I've got is on axura rom 2.2 + black froyo + stock kernel. About 40+ hours with light to moderate usage.
[Vibrant General] EvilPickle:
wholy crap!

see I was seeing posts similar to that(not quite 40 hours, but around 24+) and had me baffled why I wasn't even get 12 hours with zero use.
[Vibrant General] N8ter:
You shouldn't be draining your battery like that.

Why do people recommend this crap?
[Vibrant General] Molezou:
I used to be like you until three days ago. Now I dont hate my phone anymore. I initially thought it was my battery.

I used to flash my phone every other day. I think I'll stick with this rom until gingerbread.
[Vibrant General] princejb134:
um yea its just you

im running axura 2.2 and i have excellent battery life on my phone
[Vibrant General] Molezou:
TW says to drain when reconditioning your battery.
[Vibrant General] iynfynity:
yeah. but you should force it to drain like that. Just use it normally until the battery life dies.
[Vibrant General] regP:
From all I've read you should only recondition the battery if your phone isnt reading the battery charge correctly. It wont give you longer batter life.
[Vibrant General] EvilPickle:
Yea, ive never done it expecting a "longer" battery life.. just a more accurate one.
[Vibrant General] Molezou:
Is there a difference between forcing it and dying naturally? Don't.they both serve the same purpose?

Both stock 2.1 and 2.2 has been hogging on my battery. I can't get a day of battery life on my phone. Fyi, im using a European version of galaxy s.
[Vibrant General] EvilPickle:
I used this thread

http://xdaforums.com/showpost.php?p=8910035&postcount=31

and downloaded SystemPanel to monitor what was going on with my phone in idle. I would suggest you do the same if nothing else just to get an idea of what could be eating up your battery. Like I posted originally for me it was just the ROM/Kernel.

And a little update.. it is looking like it was my kernel that was causing my problems. been almost a couple hours now and im not even down 1% battery!!

Sweet.. thanks again for everyones help/input!!
[Vibrant General] Molezou:
16 hours since unplugged I have been on wifi and edge with 1:45 hours of screen on usage. I am now left with 61%. Heading to bed now. This should last me until same time tomorrow at least. This is about 40ish hours on one charge.

Oddly enough, I've had better battery life with JK2, JK6, and JL1 ROMS than any of the 2.1-based ROMS. I used to "recalibrate" my battery every time I flashed a 2.1 ROM, but now even without doing that battery is much better. It is worse with Nero v2 because of Voodoo though.
[Vibrant General] iynfynity:
I'm not an expert but it's just that it might be bad because your like.killing your battery if you'll always do it.
[Vibrant General] EvilPickle:
What is Voodoo.. hard to find anything specific about it.

also why im at it.. ive also been wondering about this "lagfix" or lag issue that everyone seems to have.. I wasn't able to find any videos showing actual lag and I haven't really noticed any lag before or after loading the "lagfix". Can anyone explain what exactly "lags"??
[Vibrant General] J3ST3RM4A3:
My battery life has been amazing on 2.2!

[Vibrant General] Vegastouch:
My battery life hasnt changed since ive flashed. Using Axura 2.2 w/ JL4 now and whatever kernal came with that. Battery life isnt any better than it was before.
[Vibrant General] SamsungVibrant:
I think it is just you. 2.2, especially jk6 has improved my battery life over any 2.1 release.
[Vibrant General] N8ter:
Lol. WorksForMe™

P.S. If you have any Exchange account set up in the default email client, you're doomed to get bad battery life.

Don't use the AccuWeather clock, either...
[Vibrant General] smashmouth:
1 Day 4 Hours 22% battery left... It's all about the kernel, In my stock of kernels, this is the one that get's the best battery life. Name: Stock22

[Vibrant General] regP:
What would you recommend as an alternative? I have an exchange account and I've been getting solid battery every since the stock kernel but if I can get even better life im all for it :D
[Vibrant General] EvilPickle:
Nice.. you happen to have a link to this "Stock22" kernel??
[Vibrant General] regP:

[Vibrant General] N8ter:
None of the alternatives are cheap. TouchDown and Moxier are both 20-25 bucks. RoadSync is pretty crappy. I'm not sure how any of the other alternatives function...

I've just removed my Exchange account off my phone.

There's a noticeable difference in battery life without it on there (I've put it on and removed it like 5 times now).

I basically removed all the apps off my phone thinking one of them was draining huge amounts of batter, and it didn't get any decent battery life (~8-9 hours depending on usage) until I took Exchange off.

FWIW, I got better battery life on my HD2 with Exchange and WL4WM hooked up, as well as the same Social Networks hooked up and used the GPS more - on a smaller battery.

There are bugs in Samsung's 2.1 kernel, though. There are some apps that won't run on Galaxy S with Eclair due to them.
[Vibrant General] N8ter:
You have to actually use the phone to check what the battery life is. We're looking for decent battery life with moderate (i.e. not high, and certainly not insanely low) usage.

If you have to access the web off the cell signal and have more than 15 minutes of voice calls, the batter will not last a day.

Cool story, though.
[Vibrant General] Molezou:
Download touchdown with a 30 day trial. Once you have used up your 30 days, clear your app data and it will forget you have used your 30 days. This way you can use it until android comes ulout with a better solution.

[Vibrant General] iynfynity:
are you talking about the preinstalled email app?
[Vibrant General] N8ter:
Yes, the Stock Email App in the Vibrant.

I've already tried TouchDown. It's too ugly for my liking and I cannot use a solution that doesn't properly integrate into the system decently.

I found out about it forgetting you had it installed the first time I reinstalled it, though :P

I think I made a thread about TouchDown not long ago :P
[Vibrant General] richan90:
Samsung uses a proprietary file system called RFS. This is a variant of the system used in old Windows OS, such as Windows 98/2000. It can get very slow and sluggish when you run many apps or tasks at the same time.

Voodoo converts your entire system to ext4, which is quite a bit newer, and is both faster and more reliable than RFS. This reduces (some say eliminates) most of the lag you would notice with the stock RFS filesystem.

In practice though, I've barely noticed the difference between Voodoo and stock RFS. The phone does boot a little faster, but I rarely run more than 3-4 apps at the same time, so I really can't tell.
[Vibrant General] EvilPickle:
ahh... thanks for the info.
[Vibrant General] N8ter:
Its not just about apps ur running. There are system services and background syncs which can trigger it when they access the storage as well.

That is why experiences differ. Some people have bussier social networks or inboxes than others, among other things.

Obsidian V3 (Foryo 2.2) with JK6 Modem:

23 hours with 48% battery power left. 72% on Display indicating the phone was actually used and not just placed on the desk for 23 hours.

As you can see wifi was also on the entire 23 hours.

New ROM with Valkyrie + JL5 Modem gets me the same stats. I know no idea why everyone's phone are vampires.
[Vibrant General] iynfynity:
Yeah wifi really saves a lot of battery. I wish i have it at home.
[Vibrant General] N8ter:
You can use the pbone for ten mins and it will say that for display.

It's a percent of the power used actively that it gives.

I checked this months ago, or tested rather...

Also, phone idle is always really low because the hardly ever truly idles.

Nice try, though...

I am getting far better battery life than I ever did with my stock vibrant. I was at the point of looking for another phone, however after I flashed Nero v3 with voodoo I absolutely love this phone again. My battery life has at least doubled if not more than compared to how I used my phone before.
[Vibrant General] xriderx66:
My battery life sucks ...

I tried axura got best of 8 hours.

I tired nero best of 5 hrs.

Im on ginger clone right now... About 7 hours...

Any tips anyone? I use wifi about 15 hours so use xda app alot cnet app a bit if web text no phone calls.

Please help me!
[Vibrant General] Dave08:
I'm getting terrific battery life on JL5 with the "stock" kernel, at least as good as I was getting on Bionix Fusion, perhaps better. Last night my phone only lost 2% of battery while I was sleeping for about 8 hours - I'm still having trouble believing that one myself.

Before flashing a new ROM I always flash Eugene's Froyo-that-doesn't-brick with re-partition on and then I flash 2.1 JFD before flashing the new ROM. That may be more work than I really need to do, but I've never had the kinds of problems with battery life and other issues that others report...
[Vibrant General] kizer:
You guys all realize battery life is realitive to how you use your phones. If you use 3G, wifi, bright screen, GPS, Playing music/videos all day of course your battery is going to suffer.

On Fusion 1.2 I would average at least 50% battery after 16hours of use.

I just flashed Nero V3 yesterday and I think I was 30% after 16hours, but it wasn't a true 16hours of contiuned on time since I flashed it.

However Use your phones and personally stop worrying about squeezing every ounce out of your battery. Trust me what you run kills your battery and if you flash a lot your battery use is going to be horrid because you need to let your phone stabilize. I normally at a minimum flash a new rom and wait at least 3 or so days to see the difference.

Yes you can say that the newer 2.2 Roms are killing your batteries, but have you noticed the gains in speed and GPS loading times alone are worth it. Never mind the faster downloading speeds.

Also you do realize those battery monitoring apps use battery power right?
[Vibrant General] xriderx66:
I'm on xda most of the time I check the news every 3 hours or so.

Lowest brightness

Data turned off

Wifi on all times

JL4 kernel

Ginger clone R2

About 100 texts total through the day

1 to 3 phone calls the whole day and they last 3 minutes maximum

I think I have pretty moderate use...

Also sometimes I play games but I know the risk of playing a game and losing few percents but even when I don't it still loses tons of battery
[Vibrant General] PaiPiePia:
You can eat that sour grapes all you want, n8ter.

The battery life is obtained after a day of use, whether you like it or not.
[Vibrant General] PaiPiePia:
It was taking a while ago, so I dont remember the exact time.
[Vibrant General] regP:
And in that 23 hours how much did time was spent actually using the phone? Not trying to hate but I find it very hard to believe anyone is getting anywhere near that much battery life with a significant amount of usage. I got 20 hours of battery life once, but that was because I forgot to plug it in when I got home and went to bed and it idled for 12 hours and previous to that I only had about an hour of actual screen on use.

Did you leave it off the charger overnight to monitor the idle drain? I never did understand why people dont just charge theyre phones while they're sleep.
[Vibrant General] iynfynity:
Sometimes i do this just to see if my battery life in idle is good. that's very important for me.
[Vibrant General] hpz937:

so far its been running for about 13 hours, and right now i have 15% left, with moderate use, is that good?

I normally use Edge all day opposed to 3G since I don't need it, but I will turn it on if I feel the need.

I'm running Nero 3 with Voodoo enabled.
[Vibrant General] timur525:
@kizer

GPS still sucks, speed isn't any different without any lagfixes than 2.1, download speeds have to do with your modem. If battery life sucks, we're gonna try to fix it, and of that pissed you off go on 4chan or something....
[Vibrant General] Blaqhawk:
Here is your battery

If you are that worried about battery life, you should go this route.....

http://www.mugenpowerbatteries.info...es109514_es120302495377/Products/HLI-Si9000XL

Otherwise, try and figure something out ROM/Kernel wise. Charge more, Worry Less.

I am in the hunt for a 2100mAh - 24mAh battery. That 3200 is just tooooo big for me.

I am much more pleased since I switched to the TW Nero V3 w/ VooDoo. I have probably gained an honest 20% - 30% in battery life which is fair enough until I find that battery I am looking for. I may just have one made, I know it can be done, for the right price of course.

[Vibrant General] N8ter:
Lol.

10-15 Text Messages and 2 Dozen emails are pennies when it comes to battery usage.

Most people can keep their phone plugged in while they stream via AllShare (I play music from my PC using AllShare while plugged in lying on the couch np).

Google's Reader App pushes RSS updates to your phone, so it uses less battery than Polling with NewsRob.

Using Edge All day may work for you, since you obviously don't do much on your phone (most people get more than 2 dozen Facebook Notification emails a day, much less total, especially if you have a Business Email account also set up on the phone in TouchDown or the Stock Email app via ActiveSync).

Everytime the phone gets a notification it turns on the entire screen. That wastes a lot of battery power for people who actually use their phones moderately and have "busier" email accounts and/or social networks. I wouldn't be surprised if that behavior accounted for 10% of the battery drain on these phones. They should have been a LED indicator, cause these sAMOLED screens are battery whores.
[Vibrant General] qreffie:
I've experienced great battery life on Eugene's Macnut R14 and a couple other of his roms.
[Vibrant General] N8ter:
And TBH, these threads are becomming more and more useless since I've noticed a majority of the people who post in them don't really do much on their phones except flash ROMs, and it's hard to assess usage patters in an internet thread.

A screen shot of battery usage is really, really, below useless.

[Vibrant General] mdof1337:
The custom ROMs are indeed battery hogs. Though I've had really good battery life with the JK6 leak/Modem as well as the JK6 Stock+Voodoo Kernel. I am a heavy phone user and I get 20+ hours on a full charge, as well a some really good Data speeds.
[Vibrant General] boodies:
OP

my 2.2 has been fantastic. not sure why yours is suffering so bad. try odining back to JFD then install a 2.2 ROM, I suggest Nero 3
[Vibrant General] regP:
That is very relevant to my interests also. I'd love more battery capacity but I'm not gonna turn my phone into a brick (no pun intended). Havent been able to find anything as of yet which is weird because I was able to get a 1800mah battery for my Bold that was no bigger than the stock 1500 :/ You'd think the same would be possible for our phones.
[Vibrant General] Blaqhawk:
I would be cool with an 1800mAh. This whole battery issue can vary sdo much from user to user because of sooooo many factors. I generally need to charge my phone at some point during the day in order to make it through the day. However, that being said, I (in general) probably use my phone more than almost everyone else I have come across. If I leave it in my pocket, just using it as a regular phone and maybe check my email a few times, my battery would go for a day and a half to two days. However, I rarely do that. I use my phone for everything, you name it. I have quite a few widgets running as well. For instance, at any given time, you will find 2 screens with 4x4 Agenda Widget running on them; one with my personal/work stuff and the other with my coworkers appointments and meetings. I also have 2 instances of Weather Bug Elite running, one with my location and one with the location of my family (since we done live together, but I travel often to see them. I also run a battery monitoring widget, 3G Watchdog Pro (which I highly recommend if you have a data plan), a Google Voice widget, a Note Everything widget, a Switch Pro widget, and a gTasks widget. Up until recently, I was also ring a Facebook widget, but realized that I hardly ever used it so I just use a shortcut icon now. At any rate, my point is, you can't really count one what someone else claims to be good or bad battery life unless you both have the same stuff on your phones (unlikely), and you utes your phones in the same manner. Therefore, install a ROM, run it, see if out fits your style. If it does, great, if it doesn't, adjust fire. personally, I think the 2.2 ROMs (in general) give about a 20% increase in battery life. Remember, when you first install a new ROM, you are going to use more battery because you'll be playing around with it a lot. Give it a eek our two for the new scent (so to speak) to wear off and them judge. Good Luck, Cheers.

So what your saying is I don't use my phone enough? LOL, Shame on me. I'm going to rush out and throw away my phone or exchange it for a pager. For the record I do use Exchange and get my emails via Exchange and Gmail.

I guess I'm confused how using edge opposed to 3G means anything when it comes to getting emails from FaceBook? So your saying you would rather waste battery all day on 3G to get FaceBook emails faster than to save?

Honestly you need to revisit your way of thinking when it comes to the usage of your phone. I have a guy in my office who plugs in his droid twice a day to charge his phone. I know because he barrows my USB cable all the time. I constantly tell him to turn off 3G because a poor signal will kill your battery fast.

Anyways good luck with your battery problems and I hope you find a solution.

Just order spare batteries. I ordered two off brand batteries a week after I got my phone (release week). It was like $20 off of Ebay for two batteries and a battery charger. They're still working perfectly fine.

My iPhone 2G had hood battery life, but that will just leave us to argue about the iPhone vs Android debate; so I'll just leave it at that. ;) FWIW, in case there was any question, I am more happy with my Vibrant than I was with my iPhone. Although that was debatable until I flashed the ROM.
