their service is pretty good for the folks that wants to use push for gmail, it may drain the battery but i dont know, i keep my on the charger when im at work or when ever im not using it so my battery never gets low but i get all my emails fast.
First week of using Galaxy, and Im really happy with it
Never had a faster phone but im also a newbie with smartphones,
The problem is that battery life is unacceptable,I thought it was that battery was new, but im on the 5th recharge, and i have to recharge twice a day,
I tried to drain battery completely, as i do with every phone, im on jm9 firmware downloaded here, it seems the default had better battery life,
I also disabled auto sync, but still i see the refesh icon in the battery bar,
Is this normal or i have a defective battery/phone?

Always good to do a battery reset with adb shell and remove the battery stats you have now.

after u get that running search for reset battery stats galaxy s on google to find the code to remove the stats .
Thanks, i'll try this,

I've been running 'SetCPU' and under-clocking to as little as 20% while still getting just about acceptable use of most apps (40% is much better).
This really improves battery life if you can put up with the penalties.
I know folks will say that this defeats the object of the SGS, but in some circumstances the extra battery life is a more important factor. I already have two spare batteries, but switching them isn't always convenient, so the SetCPU alternative works for me.
Note, you WILL need root.
this will certainly improve battery life
Go to wifi setting, though it may be OFF but just below that u will find a setting known as NETWORK NOTIFICATION which will be light green that means its ON. This is what drains battery like mad. First turn On wifi now turn off network notification setting and now turn off wifi. This will certainly work.

Do you always reset battery stats after flashing?
I think it reads ok the battery, it just drains quick..

Thanks advaitha
That was a tip I was looking for!
This isn't a little rise in battery draining. This is an absolutely ridiculous spike in battery usage. I left my phone overnight, and it dropped from 90% to 37% within the 8 hours I left it sleep.
Is there anything I can do? This is stock JPO updated via Kies. Will changing ROM or Kernal fix this? Because quite frankly, I am sick of this. I can't take my phone out for the day without it dying on me.
As far as I can tell, it's not the sensor bug some people are experiencing, as I'm not seeing any suspicious usage in the battery history.
Any help would be very much appreciated as I'm seriously debating getting rid of the phone. I just can't keep it with this appalling battery life.
Thanks.

Turn off auto rotation and data connection (3G). That should improve your battery life siginificantly. You don't need to check your emails in your dream do you?

Thanks for the reply.
I have auto-rotation off as default. It is really plausible that data connectivity is consuming this much power? I never had this much battery drainage in Eclair, even with auto-rotation on, data connectivity on and with the screen at maximum brightness.
I've downloaded APNdroid and will see if turning of data connectivity will help, though I very much doubt it. I'll update here in the case that it does though.
Do you have a exchange account configured?
It's known to drain your battery at that rate when not set to "Push" (generic Wake Lock problem in Froyo)
Also, if you don't mind spending a few bucks, install System Panel app and let it monitor CPU, that way you'll find out which apps are the top battery users (while asleep, battery drain is fairly equal to cpu usage, so the top cpu-usings apps will be the drainers). I have 75% battery left after 10 hours of light usage with Bluetooth. Auto Rotation and 3G enabled.

The only email I use is Gmail, synched to my phone. I've noticed that a fair-few people are having battery issues with a number of suspected causes. The exchange email setting being one and the sensor issue being another.
Would flashing to a custom ROM fix this issue? Or would it still persist? I really wouldn't mind flashing to a custom ROM if it fixes this absolutely pathetic battery life I have at the moment.
if you have any task killers installed try uninstalling.
I had advanced task killer installed and was experienced battery drain..not as much as you but if it helps it al counts

I don't use any form of task manager besides the stock one, which I use on rare occasions.
I'm really debating just trying to flash with any old ROM to see if that fixes the issue.
Are I using the ext4 lagfix? If so there's your problem there. Also to fix gallery bug you just need to root phone and use root exeplorer to copy fixed gallery.apk into /system/Apps. Putting new modded Tom won't fix it as thy mostly use old default gallery which has sensor bug. Look in search to find gallery3d.apk file

I'm not using any lagfix at all. It's stock JPO updated via Kies. The only modding I've done to it is rooted it.
How would I go about checking whether or not the Gallery is the cause of the battery issues?
Hi all,
After noticing my battery was draining quickly, and then after reading this thread , I installed Android System Info to see what was draining my battery so fast. I notice that whenever I would turn on WiFi, the phone will never go to sleep , regardless of what I set the WiFi sleep policy to. After turning off WiFi, the battery still drains heavily.
The WiFi will shut off after 15mins (if you set it to "When screen turns off" or "never when plugged in"). However it seems to keep the CPU on causing it to drain down the battery.
It would seem that whenever WiFi is enabled, the Android system process creates a partial wakelock that does not go away even if you turn off WiFi, and even when the WiFi shuts off as per the WiFi sleep policy. The only way to resolve this is by powering off or rebooting the phone.
You can verify this in Android System Info by going into Battery-History-Other Usage-Partial Wake usage to see how much time the "Android System" process holding a partial wake.
I even did a factory reset on the device; and it is still happening so it doesn't appear to be any app that caused the issue. As I said, it works fine as long as I don't enable WiFi.
I already know of two users having this issue, but I'm wondering if folks having battery problems are going through this as well. Is anyone else having similar issues after using WiFi? I'm hoping someone will be able to identify what exactly is putting the wakelock on and we'll be able to find a fix for it. Other than not using WiFi at all or rebooting the phone after using Wifi.
Does someone know if there is a utility to drill down and see which process would be causing the wakelock? "Android System" doesn't give me any more details.
Any help would be greatly appreciated.
btw I'm not using any battery savers or task killers.
Update...i have the wifi sleep policy set to "never". Also have the network time sync disabled. I am no longer getting alot of battery drain from the Android System partial wakelock.
However, this means WiFi is on all the time....which burns up the battery as well.
Do you think this is a Samsung bug or Android that won't properly let the device sleep when the WiFi sleep policy is set to anything but Never?
Hoping someone at XDA can figure this one out.
I wonder the same thing...I lose about 20% during the night when the phone is not used for about 7 hrs. Not sure if that's normal or not

Set the WiFi sleep policy to "Never" and reboot the phone. Shut WiFi off if possible overnight. You should notice a big improvement with battery life.
Devs - is there any way to see what is wakelocking the Android System process?
The WiFi sleep policy seems to be broke on the Captivate so hoping someone that really knows these things can help out to identify what is going on.
I've had wifi sleep policy to "never" since I got it. Turning off wifi when going to sleep will slow down battery drain when the phone is not in use all night?

It should. Also setting the network to gsm only will use less battery. We need to find a way to see what process is holding that lock. Any dev experts out there please chime in.

That is anything but normal unless you live where your cell signal is very weak. I see about 1% lose every 60- 90 minutes when idle. 10-12% when browsing or reading xda. Dont do heavy gaming do not sure what you should see there. Weak cell signal will kill battery life as can other factors.
I do have a weak cell signal at my house. I'll have to ck it in idle mode in my office, where I have a good signal to see if that makes a difference
On the other hand I just recently installed beautiful widgets and use it's live wallpaper. Also lookout..I'm thinking that could be a battery hog
I'm experiancing the exact issue in the op.
Android System is holding a partial wake lock of about 30-40%
My battery drains 40% overnight.
Are there any fixes for this?
The problem for me was definitely the stock email app continuously polling my Exchange server, killing the battery and my data plan. I resolved it by removing the Exchange server from the stock mail app, and by using Nitrodesk's excellent Touchdown app for mail instead. Touchdown isn't free but it's very good. And now my battery performance is back where to it was prior to the Gingerbread update.
Thanks, Google, for carefully testing this update before releasing it on the unsuspecting public (NOT). You caused a lot of grief for a lot of people.

I may be wrong, but isn't the default email app from Samsung?
Though, you are correct. I setup my work exchange on it as well and it is definitely a killer. Lately I haven't really been giving a **** and just charge my phone every night. However, I might look into this Touchdown app now.

for the stock email app you can configure the sync schedule so it doesn't continuously poll your exchange server overnight. i have my sync schedule set to push when i normally wake up and an hour after i get off of work. during off peak hours its set to manually update.

how did you set this up??
I haven't really noticed until just now that I cannot disable email push from exchange. I get over a hundred emails a day from work and it's draining my battery.
I've set it to 5 minutes during peak but that doesn't seem to do anything.
Anyone having this problem?
btw, I'm on overcome beta2.
Thanks!
Disable the auto sync feature from settings, account and sync. Its a major battery drain.

Hi DarkPal. I don't mind that auto sync is on. Just want to disable push since that is usually major culprit.
Don't know if it's a bug with the overcome version I'm running or if it's always been like this since I never paid attention to it before.
I tell you the auto sync is more of a culprit had it on last few days and had a bleeeeeh battery life. Disabled and now decent as usual.
