Try another Rom Super D v1.9.3 and SuperFast v1.3.3 are excellent Donut (1.6) ones to test your battery issue.
ok ill try out SuperD thanks
I will bet that your battery issues are not ROM-related. Being that its an after-market battery, and used, it's probably outliving its life spam. To my knowledge, batteries are meant to provide a certain number of charges, every time you plug the power cable into the phone to charge it, that constitutes for one charge. Whether its for 5 minutes, or 5 hours. They usually have a set number, somewhere around 500 charges. After that, it slowly stops holding a solid charge.
I would suggest buying a NEW battery, not used.

Youre assumption is correct, thats why I directed him to flash a Donut rom to test and see if the short battery life occurs again.
Until we hear from him we wont be 100% in our hypothesis.
Youve gotten ahead of me and commented about the battery being the culprit, damn, beat me to it. ha ha ha.
i would say its lasting longer, but only by 1 to 2 hours more. so im going to buy a new battery. thanks for the advice tho
ALSO, while downgrading to Donut, While wiping, MAKE SURE your battery is FULLY CHARGED and wipe the battery stats. Check back.
ok my battery wasnt fully charged while wiping everything and downgrading. instead of re-flashing and downgrading can i just re-calibrate my battery? sorry for the late reply
me too
same rom - same problem .
i have a genuine battery , my g1 last one hour and 12 mins with the super froyo rom.]
real shame as i love the rom .
I have that rom and it the best battery life I have found so far on this phone...
There's a thread similar to this bellow and I recommended this:
3 thinks you can do
1)check for a better rom and\or verify if your gps, wi fi and on while this happens
2)Recalibrate your battery
2A Discharge it until it shuts itself off.
2B) Recharge it back to full and then leave it charging for another few hours even after it says it is full
2C)repeat if needed
3)buy a new one...
Good luck

hi!
guys, when should i charge the Galaxy S battery to maximize his life?
In my old phone, i only charge it when the phone shuts down himself. It can run for 7 days with no problems until i need to charge again.
Should i do the same thing with Galaxy S battery?
Well, when i need to connect the phone to the PC using USB cable, it will charge anyway. Is it bad? Should i do it only when i know the battery needs to be charged (when it has low battery)?
any time you want
it should always be topped up, there is no memory effect
Some people say that we should charge when the phone has 25% or 30% of the battery. And every month we should make a complete charge and discharge.
Is this a good method to keep the battery ok?
best way is to cycle through 2 or 3 batteries
charge them full
then use them down until you get the warning, and change to new battery pack, then take the used battery to the charger

Although I don't really have any definite sources to back this up, I've read several places that Li-Ion and Li-Polymer batteries can (and even should) be charged as often as possible. You should avoid letting them run flat, apparently.
What is certain though, is that they themselves have no memory effect like NiCd and NiMh batteries have.
our SGS will nag you to death as soon as it reaches 10%, and it will constantly annoys you to charge the battery at 5%
so, no worry about running flat
Technically to maximize the life (ie. capacity) of a Li-ion battery you should charge to full when it gets down to 40%.
The cooler the ambient temperature the better - A Li-ion battery operating at 25 degrees C will lose 20% of its capacity in one year. Higher temperatures drastically increase this degradation.
Given that most people will move to a newer phone after 2 years or so, and spare batteries are cheap as chips, it doesn't make a whole lot of difference.
So, people say that we should charge the battery when it has 30-40% of the capacity.
But what is the thechnical explanation?

that's exactly what i would like to know as well at 30%-40% will make the battery totally useless if that is true
might as well take the phone with a super long extension cold with you if that were true
LMAO

I don't think that would be the best strategy, AFAIK (and read)
Li-ion packs prefer more frequent charges, even if after partial discharges, than full charge-discharge cycles.
Its also not good to store the pack fully charged. Best to store at 40% charge.
Following these 2 concepts, I imagine its better to charge the battery as often as possible, like every day, than to let it discharge until you get the warning.
Also, if you cycle through several packs, letting each one discharge almost completely, then charge it fully and move to a different pack like you suggested, that means you will be letting the battery unused at full charge for a longer period (the more packages you use, the longer the pack will stay stored at full charge).
Thats how I understand the behavior of those batteries. Just my 2 cents.

I will say what the first reply said, charge as often as you feel you have time. Do not wait for any percentage of drain. There is no memory effect and yes about once a month do one full uninterrupted cycle. The point of which is to let the device's power management recalibrate where 0 (or thereabouts and 100% of the current fill are.
Cooler is better, this is also true.
All educated advice on Li-Ion batteries is that they remain healthier for longer the fuller they are, but the chemicals must be exercised occasionally, thus the full charge cycle in one go.
One charge cycle also actually counts over multiple charges, and not just uninterrupted ones. You can drain then charge 25% 4 times and that is counted as one cycle for these batteries.
I have always stuck to this advice since I learnt of it several years back and I find my batteries work better and longer than many people I know (who stick with drain, charge methods (lack of updated information).
i agree with nailerr
Simply charge it when you need to. It's better to have a fully charged battery when you need it, than run out of battery when an important call is coming through
So, the main reason to charge it with 30%-40% left is to avoid the battery heat too much?
I found this: h**p://batterycare.net/en/guide.html
It says more or less what you guys said here.
But you need to know that i always charge from 0% to 100% my old phone. It is 4 years old and it has no problems with the battery. It can run up to 7 days without any charge... Looks like charge it that way is not so bad anyway i guess...
I have two batteries for my Captivate If I let one of them run down, then switch it out for the other that isn't fully charged (its somewhere around 60% or so), do I risk having battery calibration issues?
Thanks!
Sent from my SGH-I897 using XDA App
yes. you risk battery calibration issues even if the other battery was fully charged. not all batteries are created equal. both batteries could say they are full but still be off by a couple percentage points.
that being said the issues shouldnt be too severe perhaps slightly more drain...but who cares you have 2 batteries so you'd still come out ahead
I don't believe your battery calibration would be that off swapping between two same size batteries. I could see there being issues if you go from an extended battery, to a regular one.
I have five batteries and swap between them all the time. (I bought them while running CM7 ) I always shut-down, and then swap in a fully charged one. I have never noticed an issue.
Just bought a 3500 mAh battery off of ebay. I was wondering do i need to condition this battery? If so what are the steps? I see conflicting info all over the place.
thanks!
Conditioning? Like calibrating?
Some batteries said to drain it completely first then charge for 8 full hours to condition it. That's why i was wondering if there was anything i needed to do to get the maximum amount of battery life out of it.
That's a great question. Usually I let it drain fully, then fully recharge. It's just an old habit of mine with new batteries.
usually when you get a new battery itll have some charge in it you need to power the device on let it drain completely till it wont turn on at all then let the battery charge 8-10hrs and you should be good.
I have flashed my Att I897 with RemICS JB rom, and then I ran the battery dead. Then I fully charged it and it doesn't last 5 hrs now. I even calibrated the battery. Any ideas, or is this normal with custon rom?
Have you tried any other roms? Download a battery stat app let it run a few days and see what's using up all of the battery. Did this happen prior to flashing or no?

I have been running this rom for a few weeks, with no issues. Then went out and bought a new phone, and my brother needed one so I gave my I897 to him . I reflashed it, to clean everything up and let him put on the apps he wanted. And the battery does with in 4-6 hrs. I will d/l the stat app and see where is goes.
I have another I897 runnig the same rom, on my daughters phone, and it has great battery life still.
added thoughts
if your brother is making heavy use of the phone, with screen on much of the time, then 4 to 6 hours is normal.
running the batt dead once shouldn't kill it. there are protections in pm chip to stop before batt voltage gets too low.
aging, as in several hundreds of charge cycles, will reduce batt capacity to half or less of original capacity.

oh, and swapping the batteries between the two phones and running a few days will tell if battery age is the problem.
I'd say it's time for a new battery. 2y old battery has significantly reduced capacity. I'm using original Samsung Epic 4G Touch SPH-D710 1800mAh battery, fits well in Captivate with stock cover. Battery life is very good for a smart phone. Stand-by >48h easily, holds >18h with about 2h talk + 3-4h screen on. Currently on SlimBean 2.5 ROM. Search eBay, it's about $15 only. Avoid cheap noname 1800mAh (or even more "on paper") Chinese batteries, usually the real capacity is well below claimed capacity.

I was getting a good 10 hrs on it till I reflashed it this last time. I had great battery life with that little phone. That includes texting and FB'ing talking
I have 2 more and I still get great battery life.
I've never tried RemICS JB but I'm in doubt the ROM itself is causing battery drain. I'm getting almost same battery live with CM10 Stable, PAC-ROM, SaltyBean SE, SlimBean. Currently running SlimBean. Make sure it's not an app you install after flashing the ROM. Never restore system data from your previous ROM, just user apps + data. Look at the battery panel and you'll see what is draining your battery. Btw, clearing battery stats does nothing. You can't really calibrate the battery. Android OS will adjust battery meter automatically after 2-3 recharges.

Yeah. I found out one prob was he was trying to charge it with just hooking it up to a pc. Know it seems back to normal since he used the wall charger, for a overnight charge
I've charged from the PC many times with decent battery life results... Don't know if that's the reason why the battery life has been cut short.
A good way to gauge what is causing the battery drain would be to do as ValD said. See what is using up the most battery life from the battery panel and try to deduce it from there.
Have you tried full wipe, re-d/l the ROM, and flashing the ROM again? Double check the md5 or sha1 code from the website when you d/l the ROM too.

yeah, some PC only provide max 100ma per port, which means ~ 15 hrs. and the cap in phone for usb is set to 350ma, or about 5 hours, unless you have kernel that supports fast usb charging.
still, if the phone was charged to 100%, it shouldn't matter whether AC charger or PC used. Was he not charging it to 100% ?
fyi, the difference to phone is that pins 2 and 3 of usb are shorted in AC charger. This causes phone to allow higher charging current, up to 900ma, or as much as battery can take without overheating.
