in the battery usage graph what does the android OS include? and i've noticed on this phone it takes up ALOT of battery, why is that? is there a way to "cool its jets"?
i dont know if this matters but im rooted and running the STARBURST ROM.
thanks for any and all info that you could give me
HAHA it's Android. Things that are required for Android to run. The way to fix it would be to buy a dumb phone without Android.
Im having this problem as well with cm7. Android OS being the top consumer killing by battery.
I have been having this problem for about a week now (stock ROM). This is after a full charge the night before and I took the screenshot in the morning.

You will always have high Android OS until you start using the phone. After a full day's use, it should read 20-25% if your setup is dialed in. It will show less with Rogue kernels. They have it masked somewhat

But the phone was down to 85% power just sitting overnight.
Is that normal? (Serious question, not being a smart-ass.)

Not for me it wasn't lol, way slower than stock, and i was out performing quadrant and linpack tests on stock.
Going down %15 overnight sounds typical. Are talking like 8-10 hours?
It"s "typical," but it is NOT what this device is capable of.
The Android OS usage is not supposed to happen. It's a bug, albeit an omnipresent and seemingly unkillable one. There is nothing you can do about it except reboot and hope it doesn't re-trigger.
Without triggering the bug, I was able to sleep for eight to ten hours and drop about 2% in that time frame. THAT is what this device is ACTUALLY capable of.

So, at some point I turned off my phone and I -think- the sudden spike down in battery life is around that time.
Anyone got any explanations?

Mine has done that as well a couple of times. One time I had a charge of around 75%...rebooted my phone, and the battery was down to 15% percent.
Maybe it's just another bug we'll have to deal with until they come out with a fix.
thats strange mine doesnt have that much of a dip
every samsung product I have does this, gt 7, gt 10.1, droid charge, and this one. I don't recall my og droid, evo 4g or 3d doing this.
All phones show a dip when there is a battery pull while the phone is on....

Wasn't a pull, just a shutdown and reboot.

Stock battery stats lol

well if your phone was rebooted then that bald would have been reset because it displays monitors since last power-on.
there seems to be a bug where the cpu fails to underclock after a certain amount of usage and/or load. rebooting after intensive apps and/or before leaving the phone idle for extended periods of time seems to solve the problem for me. yes i get that too.

just press on top after you press battery usage on the screen that shows you the battery usage.
This phone is only lasting me about 8 hours before my battery will die. What can I do to help out my battery?
Sent from my SPH-D710 using XDA App
download an app call battery calibration, then after a full night of charging, go to that app and calibrate with the charger plug still in, after its done reboot phone and take it off the charger. drain the battery until it shuts off by itself. charge it back up while its off. then continue to use as normal. wait a couple days to see if the battery gets any better. my phone doesnt last too long either, im thinking of replacing the battery to see if thats the problem
Try removing some apps, that worked for me there was some apps that were sucking up my battery.

slap on a extended battery!
Kiss it three times, say two Hail Mary's and toss it over your left shoulder.
No seriously, battery life is very dependent on many things, and your statement doesn't come close to providing enough information for anyone to give you any real help. At minimum you need to provide the following during your 8 hours ...
- Total Display on time
- Brightness setting
- What you have auto syncing and how often
- Average signal strength
- Usage pattern (web browsing, calls, streaming video, etc.)
- Widgets on your home screens
- Screenshots of your battery usage and graph
My phone will also last around 8 hours if im constantly using it.
Thanks everyone for the responses. I will try out all the advice.

With moderate use, I get about 20 hours. With heavy use I get about 10-12. It's still enough to get me through the day
Love this phone!

So I read about other people having this problem with custom ROMs or rooted phones but I am on unrooted stock after OTA. I thought was one of the 60 or whatever apps I bought during the 10 cent promotion but I uninstalled them all and I still had the problem. It's not frequent but it's happened 3 times in the last couple of weeks. It's mildly annoying to have to pull the battery but the part that I can't live with is that whenever it this happens, my battery drains like crazy. The battery usage drops off a cliff and I caught this one after no more than 5 minutes. Any thoughts on this? I don't have an SD card so it's not that. Thanks!

to find the rogue app use betterbatterystats and cpu spy. not sure if they superuser. also badass battery works too.
Mine did this the other night on Calk's ROM. Something got stuck keeping the phone awake causing that cliff like drop off.
Happened to me on stock once, installed some game but didn't play it so I don't think that was the reason. It was either the default browser or the contact list.
Thanks for the replies. I figured it was an app but wanted to be sure before I started deleting things. I was just worried that this might be something to do with hardware or something.
I have same problem with different roms and i don't know what to do...

I had the same problem I figured out it was my wifi being turned on all the time. I have always heard leaving your wifi on when it's availible was supposed to save battery but I checked in better battery stats and saw there was almost 7000 wakelocks in a 5 hour period. I turned wifi off problem solved I only turn it on when I need to.
It is happend even wifi is off.

Your battery might be going bad... take it out and spin it on a flat surface if it spins freely the battery is most likely done.

The screen has been turned off for most of the 5+ hours its been up....any ideas??
Sent from my SPH-D710 using XDA App
Samsung probably hasn't calibrated the battery stats yet on these new builds, so a lot of those values are probably off from their "true" values. When I tried to run FB17 as my daily, I had to give up after less than a day because of battery drain, even with underclocking and configuring the governor to be more conservative.The SoC's power saving features probably haven't been implemented yet.
The screen has always been a problem for battery drain. I'm on 2.3.6 gingerbread EK02 and its still a factor for the bad battery life.
Are you using autobrightness? If not, what is your brightness set at?

I ran Blazer for months and never had an issue with battery life....Phantom and Calk's ROMs always seem to produce better battery life than stock.

Ya...always use autobright. The thing that's baffling is the phone was sleeping for 5 of the 5+ hours. I just don't get how the screen was 50% of the battery drain when it was off.

High android os usage is killing my battery . Does your os usage always run that low? Mine is usually around 20%

No....it fluctuates depending on use.
Usually I can go a full 16 hour work day without needing an extra charge, then last week it started not holding the charge so well. In fact Tuesday it had 30% and I left the house for half an hour, and when I came back the phone had shut off and was at 0. I hadn't even touched it. I am on a mix of Wi-Fi and LTE. Anyway, that was odd. Now look at the battery usage...

My android system has been going crazy the last week or so, usually would be at 5% our do but lately has been 40+ easy... been to lazy to wipe and re flash as I'm sure that will fix the issue, but lately I've been near power all the time so it hasn't really bothered me.
Sent from my SAMSUNG-SGH-I747 using xda premium
I flashed with Highonandroid and got 30+ hours. Probably could have gotten double if I didn't kill half of it installing all my apps back on.
What rom are you using?
On the stock image I was only getting 9 hours.

if you are not using a phone, turn it off and the battery will hold charge for many, many days.
