as I knew, original version of my i7500 is IH8, the battery life of this version is very very short, lower than 10hours without any action like call,sms,internet, or market. after I changed version above IH8, like IL1, IL3, now I used JB2(Android 1.6(Donut)), it would be used about 2days with normal calling, and internet.
besides, try to disable Auto-sync function in Setting->Data synchronization. it would be save battery. you can enable sync function whan you really need.

I want to chime in here. I tried the IH8 almost within hours of buying the phone. After 2 days, my conclusion, the battery life is horrible. I'm experimenting with JB2 now. At the moment, too early to tell if it's better or worse.
TBH, I've never had a problem with "having" to plug my phone in overnight. It's not like I'm going to be using it much when I'm asleep. It's part of my nightly ritual now; check the doors are locked, turn off the TV, plug the phone in... I've done it for years, long before getting the Galaxy.
What -is- an issue is when it doesn't last the day. If it keels over mid-afternoon then we're tending towards the realms of "not fit for purpose."
- turn off 3G or turn off APN entirely when u don't need net (using APNdroid)
- turn off WiFi
- turn off GPS and detect by wireless networks, this also helps the no-sleep bug in JC versions

In 2 days my battery dropped ~20% (JC1).
MrBrdo,
I agree, but many people won't.
I don't use the phone as an e-mail device (mainly as an internet tablet, phone and calendar), but those people for whom this device is supposed to serve as an e-mail client, it is simply unacceptable to turn off APN.
I tended to give the same answer as you do, but I learned that there are people who expect to be online all day with their phone. And indeed, they should not be forced to charge during the day (0600 to 2200h should be possible on any device, with any usage pattern, imho)
If I keep my APN on, I might get there, but only barely; and I'm a light user hardly representative of the average smartphone addict.
I still think Google and all their OEMs should bundle their forces to do something about the battery usage of this OS (which I quite like, and which I want to hang around for a long, long time... but a prerequisite for that will be that it improves in some key areas...)

I'm no 'heavy' user by any standards, though, I agree with the sentiment you make. Battery life IS a perrequisite for a phone. (To an extent, I can tolerate low battery life in a laptop, but only to a degree)
Though, I doubt if Google can do anything about it. This looks more like a hardware issue to me. I mean, if it really were a software matter, android users of other phones should be complaining as well.

You can charge it during the night, in your car, at the office... All touchscreen phones have low battery life, it's a technological limitation of the batteries.

Cough cough cough! I'm sorry, but I have to object. If you more or less have to run from power outlet to power outlet, doesn't that take the "mobile" out of the phone? We expect reasonable battery life -- measured in days, not hours. Not all of us take the car to work, and not all of us work right next to a power outlet. And that's just work; how about a nice extended weekend out in nature?
I'll agree that modern phones tend to be more battery-hungry than older ones, and that modern phones tend to have touch screens ... but technically there's no connection between touch screens and batteries -- that's just comparing apples and oranges. More likely, the problem is that the devices require more hardware for the same experience; an interpreted OS platform demands a Gigahertz CPU, whereas an embedded real-time OS would run just fine on a measly 30 MHz.

touch screens are eating more battery than normal ones, that's the connection.
What I meant to say was that battery technology did not evolve as fast as handheld technology, they need to improve the battery's energy density in order to provide decent battery life for modern devices.

it's not THAT bad, my battery lasts for 8 hours no matter how hard I try to drain it (3g, wi-fi, connected to IM server, twitter updating every 30 minutes etc.)

I have my old dumb phone for these cases but if I turn data connection off I think I can get 3 days of battery life on my Galaxy, you don't need real time email when your out in the nature, do you?
I've found that the battery on the Galaxy has gotten better after a month or so of discharge/recharge cycles too. I can get 2 days of light/moderate use out of it.
It's still a bit galling this is all you get though, considering it sits in my pocket for a fair chunk of the day, with the screen off, doing not much. Especially when it's meant to have a class-leading batery and a low-power OLED screen... but that's a different discussion
I did not state you need to turn off APN entierly. Depending on your preference, you can just switch to 2G only mode, which still improves battery life tremendously.

I totally agree with you. Yes, I suppose I could try 'running' from one power socket to the next, but it defeats the purpose of a 'mobile' phone.
In my opinion, a 'reasonable' battery life should be somewhere between 36 - 48 hours on full blast. i.e. with Wifi, 3G ... etc ON and IN-USE. Any dream phone out there with these specs ?
I was wondering how long can your mobile last while listening to music.
The other day my phone used 45% of batery in app 60 min of listening to
music at highest volume and it was pretty warm which I think is wery strange
for operation like playing music.
Is this a firmware bug or the player is too heavy for the phone?

I usually listen to about an hour of music each way of commute, and if I am not using the phone for any other purpose the battery will only drop a few percent.
Lets be realistic here. Mine lasts me 36-48 hours with moderate usage, but I don't use wifi.
Weelll, ok, perhaps I went a bit overboard there, (no, I've not seen even a laptop do it).
But, compared to my old E71, the battery life on this one leaves much to be desired. However, the other features of the phone make up for it, so I'm keeping it.

to report on the battery life of the fimware JC4,
The battery now lasts a lot longer than the various firmwares i have used.
My usage includes 3hrs of Wifi, 3hrs+ of music, 10 calls < 3min(each), a few smses.
with my above usage, i could get about 35 hrs approx. of the battery bfore it required a recharge.
This seems much better than the previous firmwares that i have used.
But, compared to my old E71, the battery life on this one leaves much to be desired.
My wife has an E71 and the battery life is fantastic compared to EVERY phone, so its a pretty high benchmark to compare against.
FWIW, her E71 with wifi on constantly could last as long as my Nokia 6230i (ie: pretty old-skool) which did nothing much more exciting than phone calls :\
It definately outlasts my i7500, especially with wifi on. If we leave both phones connected to our WAN and doing normal wifi actions like checking email every so often and the occasional facebook update mine is gone within the day, while hers will last 48 hours.

Yeah, that was one good thing about the E71 - outstanding battery life. Better than any phone in its generation or a few after it too... -sigh-

Wall charging is faster than usb charging. Does usb or wall charging gives more battery backup?
Wall charging is definitely faster than usb charging. . . However, i ve never noticed any difference in the battery backup (ie, if they are charged for exactly the same level. . . .)

Battery capacity did not increase as much as average power consumption. So it is only natural that battery life will be shit. Considering the devices do all they can to conserve power when they can, we have amazing battery lives (~2-2.5 days for me).
Now if the galaxy had a 3000+mAh battery in it, then we would be talking.
As a comparison:
My old P1i Sony Ericsson had a 1050mAh battery!! A 240MHz processor, small (and shitty compared to the galaxy) screen. And nothing special (UIQ 3 operating system though)
The galaxy has a two processors, one clocked at 500+Mhz, a much bigger and brighter screen, GPS, Compass, accelerometer a better operating system.
And yet, the battery is barely 1500mAh. One would expect it to be in the high 3000 mAhs if it followed the other hardware.

You know, I never thought of it this way. It makes a LOT of sense, now that you mention it. Any chance someone has an external add-on to improve battery? .. on second though, never mind. Just thinking of how ugly some of those made the Palm Pre, makes me jitter.
I've only ever owned 2 phones before the i7500... a Nokia 3310, then a Nokia 6230i. The reason I only ever owned 2? They worked perfectly, never broke, had great battery life and were as robust as a tank. The only reason I ever upgraded was to take advantage of higher res screens and more internet connectivity (which tbh, was pretty limited in the 6230i but still a step up from 'non existent' in the 3310).
The only reason I jumped ship to Android was because Nokia is STILL hanging onto that damn Symbian.... Urgh. Its a horrible operating system, with horrible apps that are horrible to code for. Why are they still making phones and infecting it with this crap? Hey, Nokia.... take your good, robust hardware and stick something useful on it! Look at the N900... Nokia hardware + a linux based OS and its made every halfway tech-savvy phone user in the world masturbate simultaneously. Then what did they do? Market the buggery out of their flagship "N97" which is infected with Symbian. Urghhhhhh.

really good way of putting things !!! I dont think that galaxy is the only android phone facing battery problem . is it ??

vent used an iphone . . so ve no idea abt iphone's battery life . . .
however, I just cant phantom the possibility of android loosing to iphone on any feature .!!!!
Well ! when i spoke abt android battery management, i was thinking of the infamous sleep bug that eats away the battery life . . . since the bug has noting to do wit battery management, maybe i was wrong in concluding that android has a battery management issues.
I put my phone on 2G data only and its increased the battery life significantly. The speed reduction for most tasks isnt noticable (ie: facebook) and normal background tasks like email checking and receiving tweets are fine, but when browsing its worth flicking back to 3G to save frustration at load times.

they all "handle" their processor
battery tech as been practically standing still ever since they came up with li-ion and they've just been left in the dust by the brutal development speed of ic's
nano technology will start creeping into batteries but that'll mainly just massively decrease the time needed to recharge (less than 10 minutes to fully charge).
What we want are radioisotope batteries, I'd like my battery to last the life of the phone

<face-fault> Ok, what I meant was does anyone know an android phone that has a good battery? My definition of good means, really long lasting, despite what you run on the phone.

No, there isn't one and there won't be until battery tech gets better. And when it does we will all have the possibility of awesome battery life (if you'll purchase the new batteries)
