Curious what everyone else has listed as cell standby percentage listed in battery usage. I just happened to look and mine is listed as 100% without signal even though I have had signal all along. I wonder if this could be a bug like the 50% without signal I experienced with my cappy.

My cell standby is 6% currently
Mine is 21%, Android OS at 59%. Signal is constant yellow, which is odd since it was in decent signal much of that time.
Well that is weird, mine is reading 100%. I wonder what is going on.

OK me thinks maybe I wasn't clear in the OP. What I am talking about is when you bring up Battery Usage and then click on Cell Standby it then brings you to the break down of the Cell Standby. There you will see Time On as well as Time Without a Signal. In my case the Time Without a Signal is reading 100%. What is everyone elses reading?
Time without a signal: 31% - rather surprised it's that high
To the OP, I was just about to make a thread on this because I knew I couldn't be the only one with this problem. I've had this bug since day one, it always says 100% no cell service.

I'm not sure if it's the same thing but in the international version it's a display bug and for some reason if you go into settings--about phone---status, the % starts to drop.
Oh wow. I haven't even looked at this until I saw this thread. My cell standby says 3% but it says I've gone without signal for 96%. And I've been in coverage for most of the day

Nope, no Google Voice and my Time Without Signal is 100%.
maybe they miss word it. maybe it should have read "Time with Signal"... cuz I am on a Microcell... and I have signal alllll the time
Just saw this thread and checked - I'm another user with 100% time without signal indicated. Been in decent coverage most of the day. I have google voice installed.
Mine is 13%. Still weird

It seems to be a known bug with the GS2. There are threads discussing it in the I9100 forums. Ever since I went into About Phone/Status my time without signal percentage has stayed St 0%. I guess it's kind of like the 50% bug with the GalaxyS1.

Checked my wife's SGSII tonight when she got home from work. Reported cell standby as 6% of battery use, and 0% time without signal. She has Google Voice installed as well.
A couple of maybe related items:
a) When we brought both devices home, hers connected to our MicroCell with no problems. Mine would not connect at all, until I did a sim swap with her device. After swapping back to our original sims, both connect to the MicroCell.
b) with very similar time off the charger today (me at 10 hours, her at almost 12) and similar screen on times (me: 1hr 27 min, her 1hr 11min) she had 60% battery remaining, I had 33%. I am running some additional apps, and used google nav for about 6 minutes. She was in wifi coverage all day (except while commuting) I had no wifi all day. Not sure if the battery burn difference is justified by those differences or not - or if they are possibly somewhat related to the 0 vs 100 time without signal indication (I was only showing 7% battery drain from the cell standby).
I too have the 100% "bug" I also read in the i900 threads that once we go to:
settings>about phone>status the "time without signal" percentage will begin to drop. I can confirm it. It's at 98% for me now. I seem to have pretty good battery life. About 16 hours on a single charge. I think its just a bug but makes me wonder if my battery life would last twice as long with "time without signal at 0%" I do not have google voice and all the apps and widgets I have that can be configured are set to sync manually (with the exception of the google apps) (auto sync is on).

I have noticed my battery sucks lately. I know the battery isn't the greatest but I was able to get easily a day of use out if it. Now I can barely go a day. I purchased beautiful Widgets, battery indicator and xda app all last week And it seems after that is when my battery went to **** .I used launcher pro for a bit too but started having lag problems so I removed that. Today I uninstalled beautiful Widgets. I'm on wifi and in airplane mode. As I'm typing this I've lost %2 already. Wtf is going on? I have GPS Bluetooth and usually wifi off. I have use only 2G networks, sync only gmail and screen manually set and set to low 30sec TO.

Quick question, which ROM are you running? Ever since I switched over to leaked JI2, every couple days I notice that after running one of a few apps, the CPU just seems to go into overdrive. The phone gets really warm and the battery drains ridiculously fast. So fast that even plugging into my car charger won't charge the phone, even on idle. If I reboot, the phone cools down and the battery drain goes back to its normal, slow self.
I haven't narrowed it down to any specific app yet, but it seems to be either, Foursquare, Great Land Grab, or Bubble Blast.
Foursquare I have, I don't remember when I installed it. I am actually just running stock TW.

I get 15hrs... I am not ROOTED! I did the drain battery life process twice. This is with moderate usage. I am planning to do the drain battery process once a month cuz I hear it helps with battery life. Possible that u install something that's killing your battery.
Solution do the master reset if that doesn't help then it can be the battery is no good. I know that this is with the stock rom. If u are using another rom that's maybe the problem. U can try switchig roms to see if this is the problem. I hope this information has been helpful.
Does the master reset remove everything ? I have all my pics/videos on my phone meM. I have music and avatar on SD.

It seems as though it drains faster in standby with nothing running. I removed FourSquare last night and have nothing running as far as widgets. I'm going to reboot and see. I've had it unplugged since 7am this morning, after a little over an hour I lost 2%.. not that bad I guess..

I've had this happen a few times. For me, it's usually because my battery status gets thrown off somehow. The phone would read that I have 55% battery life left, but it really only is at 25 or 30% and it always feels like it's draining fast. I usually turn off the phone, pull the battery out for a few seconds and then put it back it. When I turn on the phone the battery percentage is corrected and the phones seems to be back to normal battery use. I don't know why this happens.

This was suddenly happening to me today -- my battery started draining very quickly, mostly on standby (I usually have quite good battery life). No new or unusual apps installed in the past week (I don't use Foursquare).
I gave it a power-down/battery pull; no adjustment in the % as described in the post above, but it seems to be draining more normally now. Weird....

Same thing happens to me every couple days. Rebooting the phone fixes it every single time though, so it's not a big deal if I catch it in time. If I didn't catch it, I'd estimate my phone would be drained (even in standby) within 4 hours or so.

Same here, I rebooted after removing FS and some other apps/touitur and got 1day 13hrs on the next charge with pretty moderate use. So whatever it was, it's gone now. If it was FS hopefully it's fixed soon.
Had a similar experience, with battery % entering freefall every time I turned the phone on. Two things helped:
1. I did the drain cycle. Drain the battery completely till it shuts off and charge it to full while off. This does not 'fromat/form' the battery in any way it just helps the phone to calibrate the meter.
2. I uninstalled few apps that I suspected were draining the battery.
I advise you install JuicePlotter and see the graph of battery drain. You'll be able to tell if the phone is entering standby or not. Thanks to some culprit apps (still figuring out what it was exactly) my phone was not entering standby at all hence the crap battery life.
I unplugged my phone at 100% charge around 230am, woke up around 1015am with literally 50% left. I had WiFi on the entire night (strong signal).
Unplugged 7h 39m
Cell standby 30%
Phone idle 29%
WiFi 16%
Android OS 8%
Maps 7%
Android system 7%
Display 2%
I've stopped blockbuster, removed city id. My only widget is the clock/weather widget set to update every 2 hours (hence maps).
Auto-Sync off, Facebook/twitter updates off.
Looking at my battery history under partial wake usage there is nothing abnormal. What could possibly be killing my battery so much?
I'm really looking for some help here guys.

I was on WiFi the entire time.
If your rooted. I've had excellent results by setting a "screen off" profile in setcpu to a max setting of 245. It dramatically improved my standby time. I lost a total of 6% leaving the phone off the charger friday night. I've mentioned this in a few threads already without much response, but it works. I set up a test for this on a DF thread.
I think something is ramping up the processor during standby on these phones. That tweak helps a lot.
Good luck
System panel is what you need to find the offending app. The paid version though, but its totally worth every penny. It let's you track individual apps and what CPU they use, and shows you a top list of highest to lowest. I use it daily to track my apps.
Off topic, I've been unplugged for 15 hours now with 71% battery left. Of course this is over night idle use, but ginger bread made enormous improvements to idle power. It stays level at 10mA in standby which was never that good before.
My experience is almost exactly as the OP. I just posted this screenshot in another forum. I'll share it here. I did the exact same thing as the OP. I charged it to 100% and overnight it dropped to 49%. I haven't the foggiest idea what is killing my battery.

My battery life in 4G is terrible (no wifi on, no bluetooth, no email, facebook, etc., checking automatically). In my 3G area near my work I get much better life.
Not rooted yet.
Being there's so much difference in battery life, I was curious if there might be a bad batch of phones. My phone gets great life and my dad's gets significantly less. He works about 2 blocks away from me and actually has a stronger signal in his building than I do at mine and his battery drops like a rock with nothing running. I'm rooted and froze the AT&T bloat. He's stock.
My serial number contains a PTM and the end number is in the 40000's. His serial number contains PZK and ends in a number in the 30000's. If you have time post your serial # info and how your battery life is.
I returned my ladies OG and now her battery life is better. Even b4 I rooted it drain was better from prior phone. Could be a batch. That's my lead as well

Does this phone have the ability or need to reset battery stats? I know you couldn't do it, or it was unnecessary on the SGSII. Just curious if it's a calibration issue.

Resetting battery stats actually has no correlation with battery life whatsoever. It is not what controls the percentage that we see in screen. I believe it just tracks what apps or system files are or have been using up the battery. Battery stats gets an automatic reset whenever you reboot anyways.
For those with bad battery drain, just try and see what your serial numbers are n post it here to compare.

The battery life on my phone and seemingly most folks is great. Granted some folks probably live on the cusp of LTE coverage in their area and the radio is killing the battery while liking for signal (that happened to me with my EVO 4G).
If it were all devices, then only the battery life fanatics who shut down everything would be seeing 20hrs on a charge.
I think there's a bad batch of hardware or there.

seems odd that those who are having the issue are not likely to make to 10hrs on a charge (often 1/2 that)...while others are bumping 20hrs (myself included).
i have 4 emails on constant sync, as well as, facebook, weather, xda and a chess. each day has a couple hours of screen time. 1hr each day of either Pandora or Audible. 20-50 text and @45min - 1hr of phone time. ... in case you think i put my phone in my pocket and forget about it.
granted, i do connect to wifi at home and work. and i live in an area where i have solid LTE coverage at all times.
audible and screen time are my worst battery drains.

We got ours off the box. Not sure where you'd get it in the phone.
Did a little more research. Set them side by side for an hour with screens at same brightness, always on, with Nexus live wallpaper running. Both were hooked into wifi and the microcell. Battery usage over a 1 hour period was pretty much identical (within 1%). Then did some web browsing and hit all the same links and drain was the same. We thought it maybe was just battery conditioning. When I first got it I did 2 full drains and recharges with it off. He did that about a week in and thought it was fixed.
I left and a couple hours later his battery started to tank. Only thing we noticed was his accelerometer hung for some reason and had 5 hours on. He hadn't used anything that should have turned it on so no idea why it got stuck. Turned it off and the battery usage slowed to what one would expect. Then it had another couple minute burst of dropping. that was the last I heard.

My s3 battery is awful! I'm not sure what the problem is. I'm not rooted, I have no roms and I run everything stock. Today I went to clinical at the hospital, I unplugged my phone at 6am, by 12pm my battery was less than 40%, by 2pm it was yellow. I used the phone for about 30 minutes throughout that time during my lunch period using Facebook and texting. Literally, only around 30 minutes of usage and this happens? The phone is only a few weeks old. It seems the major problem is maps. I always get messages that maps has unfortunately closed yet I've never once used maps, haha. I though updating it might help, to no avail. I took a screen shot of my battery stats, and at school maps was at 65% usage as opposed to the 54% as shown in the photo. Either way this is ridiculous, makes me regret getting this phone. If anyone can help I would greatly appreciate it or let me know if this is normal though surely it's not.

I've never have GPS on, ever, unless I want to use it. In which case I turn it off immediately. I just cleared the data and cache on maps. Also, my phone does state I'm roaming anytime I'm on not using 4g or 3g, data and wifi is usually off. In my notification bar it does shown the gps signal, but it's not actually using it, if it's using it it shows brs similar to the wifi indicator when it's in use. This is a weird tick with verizon. So I checked my location services and the only thing that was on was location history, which I went ahead and turned off. Will report back regarding battery life.

Taking a close look at the long battery review thread, while there is a lot of information there regarding individual battery usage, the screen-on and overall usage times vary by a lot. It is impossible to draw conclusions regarding why the results vary so much, because most people did not give enough relevant information there.
I think it will be very interesting if we all used the same *comprehensive* method to compare our battery usage. We could really discover important things about our individual usage and how it compares to others (and how to make it even better).
It is important to note that when battery life is low (in comparison to other G2 users), sometimes this could be because we are taxing our device with heavy usage (and nothing is actually wrong), but other times something is definitely wrong (wakelocks, bad phone reception, etc.). This thread will help each and every one of us (that get lower than expected battery life) understand which of these two possibilities is correct for him (something wrong VS taxing usage).
In order to do this, let's use the excellent "GSam Battery Monitor" app, which could be downloaded freely from the Play Store.

Is this really necessary? The G2 has a fat battery. But any amount of power can be drained if you drain it. Enough said.

I say let's give this a shot. This phone has a beefy battery indeed, but still, some of us are posting 7 hours screen-on times, while some of us only 4. Let's see what this thread will provide us with. I have a good hunch this will be a very revealing thread.

Okay Well in the interest of troubleshooting good luck. I get 1.5 days easily with a good amount of music play. I always suggest people delete the Facebook app and use it in the browser, and disable data/sync while you're in a bad reception building/area

Don't delete face book...use greenify. Turn off location sharing unless on WiFi. No Google now. Simple

Yep, these are some solid good general advices.
I could only drain the battery to 50% today, so I'm posting this for now to get this thread running (and tomorrow I'll post the 10% results). It's funny because I have no trouble finishing the battery everyday, yet today it's giving me "problems". It's like it knows it is being monitored, and the battery hogs are afraid of being greenified...
Let's get over my results in the main screen:
Phone: yes, I did not use the phone to make phone calls. Not unusual for me...
Screen: almost 4 hours screen time, pretty impressive considering the phone has been running for more than 13 hours, and the battery is at 50%. On the other hand I did not make any phone calls, so this could be part of the reason for that excellent screen-on time. Btw, I'm using "Lux brightness control" instead of the LG2's pathetic brightness control feature, the Lux app itself drew practically zero power (as can be seen at the "App Sucker" screen, or actually, you can't even see it because it's too down in the list).
Phone Radio: At 7.9%, I don't really know whether it's good or bad, although this is definitely not a major battery user. I've attached the cellular reception screen too, just so people could reference with theirs. I think overall the reception is pretty good according to that image.
Wifi Active: The Wifi has been on the entire operating time. Most of the time it was connected to my home router, and some of the time it was not connected at all, but still on (when I was out of the house). I'm attaching the Wifi screen so people could see how much traffic the phone had through wifi, for reference. With only 3.9% battery usage, I think there is no need to turn the wifi off, ever.
Held Awake: The phone was awake for 1 hour (while the screen off, that is). Out of 13 hours being awake for 1 hour, I'm not sure whether this is good or bad. This will become clearer when more people will post their result here. It says that the power that was drawn during this 1 wake hour is 0.0%, I'm not sure if this is true, or some kind of inability of GSam to calculate battery usage for this awake period (if GSam IS correct, then I guess I don't understand what's the point of deep sleep, if the phone draws practically zero power even when awake...).
Bluetooth: The BT was on the entire operating time, but connected to a device only a short amount of time. In any case it drew no power according to this screen... like wifi, I think there is no need to turn the BT off, ever.
Regarding the "App Sucker" screen, I can't really say anything intelligent about this, no app seem to drain the battery too much. The 4 hours screen-on time was mainly spent browsing the internet, using Whatsapp, watching youtube, using XDA app (not even listed in the first screen) neither of which seem to drain the battery too much...
So, now that we have some reference (and a reference for a pretty good battery behavior, I think) It will be interesting to see how your results compare...
Just a quick question. I work in a building where there is terrible service. I mean so bad sometimes I get none at all. How does turning off mobile data save battery. Essentially your phone is still trying to connect to the mobile network all the same. I'm kind of looking for a technical explanation not just the 4g uses more battery type.

Don't forget, the vzw version will throw a wrench into these comparisons.
Thanks Devs. From my VZW G2.

If you have bad cellular reception, turning off mobile data can help, but as you said it won't completely solve the problem because the phone still needs to connect to the network so you could talk and send SMS. I think switching to airplane mode (and using WIFI) is the best solution for battery life in this case. Still, I think you should use GSam to really see how much battery is drained by your bad cellular reception.
I am using it now. Waiting until it drops to around 20% to post my results. Will get back.
Edit:
Here are my statistics. You think my phone just has bad reception and is in a bad area or there is something wrong with my antenna? My old Droid Razr HD was the same way, barely any service. I'm definitely not staying with Verizon. I pay out the noodle for "the best service" and I get crap. I live on Long Island outside New York City, my service should be amazing.

Ok, as promised, here are my 10% results:
Phone: did have some phone calls today, though nothing significant. I guess my usage can't really tell how significant phone calls are going to be with the G2, though this should not be a significant battery drainer for most.
Screen: As you remember, yesterday, after 13 hour phone usage, I had 50% battery, I had 3 hours 47 minutes of screen-on time. At that point I thought I might get over 7 hours screen-on time, but here I show about 5 hours 25 minutes. I guess that if I completely drained it, I would have gotten close to 6 hours, not bad.
Phone radio: seems similar to yesterday, about 10% of the battery... I still get good reception, as the image shows.
Wifi active: Wifi had been on the entire time, using 5.6% of the battery.
Held awake: So, yesterday after 13 hours of usage, the screen was held awake 1 hours. Today, after a total of 31 hours, the phone was held awake a total of 3 hours. It seems that the phone consistently is held awake for about 1 hour, every 10 hours of operation time (under my specific configuration, that is). I still find it weird that this "held awake" time did not tax the battery at all. How is this possible ?
Bluetooth: was on the entire time, not connected most of the time. Zero impact on battery.
Regarding the App Sucker screen, similar to yesterday, can't say anything special about this. This day I kept browsing the interned using Opera browser, and added another hour using Runkeeper with GPS tracking (with screen off). After a full cycle of battery usage, the main battery draw comes from the Home launcher, next is Opera browser, and then the apps become pretty much insignificant in terms of battery usage. Maybe two last points here: I'm using both Lux brightness control (to control auto brightness) and Delayed Lock (to remove the lock when connected to certain wifi points and BT devices), both of these apps always run in the background, yet consume practically zero battery, so high recommendation for both of these (they also work great with the G2). Last point, I'm using all the google location access services (everything is turned on there), and I really don't see this taxing in any way, using this GSam report.
That's it for now. Waiting for your results for comparison.

Interesting results. I thought this thread would be revealing, and it doesn't disappoint already.
Your phone reception is pretty bad, much much worse than mine. BUT, you can see that the difference in battery draw is not really significant between my case (I have great reception) and yours, in both cases the phone radio took about 10% of the battery. It seems that the phone reception qaulity doesn't make much difference on the battery (whether it's pretty good, or pretty bad. Maybe this will change if the reception is horrific... like 0 and 1). Comparing my GSam report to yours, you will gain practically no battery advantage by making your phone reception better (at least considering your current phone usage - you barely made phone calls, but still phone reception is also important in order to keep the phone connected to the network, and also for mobile data...). This is REALLY surprising, I thought that when comparing my excellent reception to your very bad one, if I got 10% battery usage (for phone radio), you'll get something like 30%. This did not happen at all, surprisingly!.
Your Held awake time is pretty much similar to mine, as evertything else is similar to mine (wifi active, etc.), yet you seem to get significantly less screen-on time than I. I can think of one explantion: I see you are using G2's automatic brightness control, which is pretty horrible, while I use Lux brightness control, which can reduce the brightness much much more, when it's appropriate. I really can't think of any other major contributor to your battery drainage in comparison to mine...
One thing still keeps me bewildered: why doesn't the "held awake" period tax the battery ?? I mean, the phone is awake, yet no battery is being used... how could this be possible ? Is this a problem of GSam which can't read this information right ?

When you turn off mobile data the phone stops searching for a data connection, thus this battery draining process is halted

Barely read through the details but I charged my phone to 100% last night, pulled it around 6am today. Been texting and tweeting moderately. Made a few phone calls, checked voicemail. Used the flashlight a couple times and took a few pictures, flash off.

This is true but look at the sent part of data of the phone radio. My received data is much higher then yours but I can assure you I only receive data via WiFi because my phone signal is so bad. Your sent in comparison much more data then me probably via your phone signal.
This is also very important. I had my mobile data OFF while at work today. I have a shift tomorrow where I will keep the mobile data on and post new results.
Edit: Also about the phone being kept awake and not using any battery. It does seem odd. Perhaps we should also use the orginal screenshots of the stock battery app (pending you still have stock rom).

But, I don't see how the stock battery app will shed any new light on the kept awake period, if anything, the stock battery app is less detailed regarding almost everything...
