This is not a battery thread. I just wanted to do some maths based on some findings of my own.
I post this screens, taken at 50% battery. I rebooted when full battery for a fresh graph. I'm running "stock" 2.3.4 KG1. Data is always on, two push mail accounts, display on Auto, no gaming, no photos for today.
So, if the graph are accurate (I really doubt that):
1. 17 hrs 38 mins total time on for 50%
from this:
-1 hr 48 mins phone calls
- 45 mins Android OS
-1hr 2 mins display on
-Android system (the thing responsible for widgets, push mail and so on, basically for apps) 7 mins 50 secs!
-Phone idle 16 hrs 35 mins. TIME WHEN NOTHING IS SUPPOSED TO BE RUNNING IN CPU FOREGROUND
- Navigon comes up with 11% BUT I NEVER USED IT- and there are no details on CPU usage either.
- I used 20 mins of sync Wifi for the later part of today, wifi doesn't show on the graph- no clue why.
Here I stand pretty puzzled:
1hr 48 mins of calling + 16 hrs 35 mins of idle is 18 hrs 23 mins! assuming that idle does not include when calls connected and screen off .
Here are the figures for the AOS and how life would be without it.
Android OS chewed 14 % of the 50 % battery. Calling ate 43% for 1 hr 48 mins. If it wasn't for AOS bug, I would have had power to call for some 36 more mins to get to the 50% battery. That's like 30% more talk time without the bug.
Display, set on auto, drained 10% of power for 1hr 2 mins. Android OS bug stole almost 30 mins of display time for every hour . This is 50% wasted power.
Phone Idle is 4% for 16 hrs and 35 mins. So, basically, every minute under raging AOS eats 0.31% of battery. for every 1% the phone idles for 4 hours and 9 mins (and ideal stand-by time of four and an half days ). EVERY MINUTE OF ANDROID OS EATS AWAY 1 HOUR AND 22 MINUTES.
Also, the Widgets and all other stuff are actually consuming half the power eaten away by AOS.
So, if by miracle, the faulty driver is resolved by Samsung, we should get :
30% more talk time
50% more display time
350% more idle time.
Or, for the connoisseurs:
Android OS comes in, battery goes flat. No miscommunication. You can't explain that.
Good post, my own experiences (i only have my GS2 a few days coming from a HD2)
I deleted my battery stats last night and left my phone on,data was enabled nothing like bluetooth/GPS,etc,brightness is set to automatic brightness the phone was at 99% and from 12.29am to 09.59am this morning when i checked it was 83%,not too bad i suppose but could be better, i have fast dormancy disabled and i froze the Samsung apps with Titanium Backup,however the Android OS was at 41% and Maps and Cell Standby both 15%, since then ive been using the phone for some Internet, 1 call and sent a few text messages and it's now currently 12.41pm and it's at 47% and the display now shows at 35% and the Android OS is 23%, im running Lite'ning ROM 1.5, does this seem normal or quite excessive im in 2 minds myself, does the Android OS usually be as high as that when in standby,when im using the phone for a period of time it appears to go down as low as 8%.
All I can say is, use ATK. Its just working great for me.

Thank you for this. It makes the problem clear to see. There are a lot of people saying things like "it all adds up to 100%" or "hey Android OS is high, but my battery life is very good".
As you say, we'd get much much better battery life if it weren't for this damn bug. Battery life can be good now. However with a 1650 mah battery, without Android OS wasting precious energy, it would be great...
Great summary!
More info
I have depleted the other 50% of battery so I'll post the values. The phone charged when connected to transfer the files. Well, at the end of the day, it looks like the that:
1. Voice calls drained 39% of battery for 3 hrs and 19 minutes.
2. Display is 2nd with 14% and 2hrs and 20 mins.
3. Android OS gets 3rd place with 12% and 1hr 20-this is the kernel running.
4. Android System- the one you bought the phone for- is pretty shy, only 9% . I repeat, here are all the widgets, Sammy updater, mail and so on.
...
Dialer is 6%, Navigon gets 8%, Cell standby - that's the radio FW- 5%
Phone Idle is the champ with 3% @ 31 hrs and 17 mins. That's the spirit.
Also, GPS status is eating 2,2% for every minute.
Bottom line: if it wasn't for the AOS, I would have had -see below( let's be real and give each process it's share so I'll split the AOS drain to get everybody happy)- before running for the charger .
1. Phone calls. 5.6% more battery- and 23 minutes more of talk time.
2. Display. 1.7% 22 minutes more.
3. Phone idle 0.9 % almost 10 hrs.
The rest of ~4% is shared for Wifi, Cell Standby and android system.
These numbers are valid for my usage pattern, phone calls all day long/ that's why i bought a phone for/.
I might draw some lines here and reveal some facts ( the values might be different according to usage pattern):
ONE MINUTE OF:
AOS bug drains 0.15%
Voice calling (I live on a good network signal area) depletes 0.13%
Display on is lower than calling @ 0.10%.
GPS could be chewing 2% when polled thoroughly.
Widgets and other Sammy crap are not scary at all. In fact, I find them pretty decent under this SW revision.
Maybe some will find these values useful.
Maybe we don't realize the impact of implementing a bad driver. For me, it all makes a lot of sense and annoys me more. Too bad we not on Icrap's ship, the news would have been all over the web.
One last thing though.
There are 2 main issues withSGS2: AOS and wake up lag. Never listen to any wise guy that says the lag comes from deep sleep and you should be lucky if you have it because it means the phone is SLEEPING and not eating away battery. I've noticed lately a trend in trolling this issue. I am confident that the guys behind this reasoning are on the same level with the guys that came up with Killing task managers and empty ram crap in Linux. And they even wonder why the alarm is not working after RAM flush.....
Wake up lag is a side effect of some nasty crap hogging the CPU's front bandwith. I bet any trolls here that when the lag is gone so will the AOS bug be ( at least AOS will be under Idle in %).
My wild guess is a radio issue somewhere.
same problem omg :S i hate this !! but phone is great !!
KG3 Report
Hi,
I have a new report to post, this time under KG3 stock rom. This time WI-Fi off whole time. I used the car dock for 10 mins.
1 day 7 hrs and 57mins from full charge to 15%:
Voice calls 2 hrs and 35 mins -37 %
Display on auto 2 hrs and 27 mins 20%
Android system 13 % Cpu total 10m 16 s
Android OS 9% 53 min 45 s
Dialer 6% C
Cell standby 6%
navigon 4% pops up,never used it
Phone idle 4%
Although it seems the AOS got less cpu with this, the improvement is not so clear. I almost talked 1 hr less with this one.
My android is 49% of 15 hour up time from last charge but the CPU time is only 2 hours 15 minutes for it. Hardly 49% of up time. Do you think maybe firstly there is no bug, its a bug with reporting not AOS usage time and that the phone hardware just eats a lot of juice even in standby. Just a thought. The battery lasts pretty good for the fact that its so small, there's an amoled screen and a dual core processor. Perhaps even in idle the hardware just draws a lot of power to allow a quick jump from standby to fully activated without any waiting around.

Could you post some screens?
Android system is 49%? the percents relate to the battery usage, not the time.
ALSO VERY IMPORTANT:
Dual core CPU should draw less power in standby/idle/sync. this is the idea behind dual/quad cores. If you have the time, read on how do they stack processes.
Deep sleep is not working properly. How come my WIN7 x64 wakes up in less than 1 sec from standby> win kernel is around 300 megs vs 17megs Android? It is a driver issue.

So instead of writing here, we should write to Samsung, correct? I hope this will be resolved soon, OTA update should do nicely!

Believe me, I've tried the highest official way there is. They keep blaming android/google. I even pointed them some apps that were using obsolete scripts and 4-5 ro.* that were hogging the cpu. All they answered is that is under revision. then somebody from the work asked me what the f*** is this communication about and told me to use the nexus S instead.
Here the results of a simple test I did:
KG3, CF-Root, 8 widgets, skype and viber, 2 e-mail accounts. The usage was roughly the same (mostly internet browsing, e-mail cheking and only a few voice calls 20min approx.) The difference is that in the first day I left the sync and WiFi on all the time. On the second day, I left both sync (including background sync) and WiFi off most of the day, except during the time which I was using it (browsing internet, updating market apps, checking e-mail, etc.) The result, as you can see in the screenshots below, is that with sync and WiFi off, I've got almost 26h extra of battery life (18h18min v 1d19h52min). So, for me at least, the battery drain is WiFi+sync.
Looking at the pictures, compare phone awake v screen on. With sync+WiFi, you'll see that the phone was awake many times with the screen off, whereas it didn't happen when the sync+WiFi was off.
Therefore, I think it is better to turn sync+WiFi on only when you really need it, and not all the time. That's what I'm going to do from now on.
Ah, no powersaving settings enabled in any case!
Android OS @2%
Still under KG3, nothing installed lately, nothing at all:
Full battery in the morning almost flat in the evening with very light usage- I on a sort of holiday ....
1. 16h and 2 mins it lasted
2. 57 mins of calling
3. 51 mins of display time
4. Android OS WAS 2 % running for a total of 3 mins
REALLY SAMSUNG?
I want my AoS back.....
i rooted the phone yesterday, screen on time was around 4 hours or so..10% drain per hour average with screen on-off.
freeze all bloatwares and aos went down to less than 10% (was in 40s).
will see battery improvement today.
after root, i still got the yellow rectangle at boot (havent remove it yet)..will it affect battery life? any input?
I froze the WIFI Sharing service and my phone went from dying 25% over 4 hours at work with almost no use (and WIFI off) to lasting all day, or not charging at night and lasting all night and through the next day.
Just saying.

If you don't understand that the yellow triangle ONLY means that the kernel you have flashed does not have the correct signature (i.e. it is a custom kernel) then you shouldn't really be messing with root at all. How would this be relevant to the AOS bug or to battery life?
What is your view on juicedefender?
Battery savers are pieces of **** that turn help battery life by constantly changing the device on something more like Nokia soap.
My Personal view on software that claim to help save on battery was/is as it is about task managers on Android... somehow useless mainly for a few reasons:
1. They interfere with running processes and I haven't seen one really optimized for the system. Some are behaving limiting the performance. Which isn't a good thing.
2. I found that even Watchdog is a drain culprit when it's running after a limbo limbo process.
I have seen this issues before, in PC world. 8-5 years ago, Sony was loading their Vaio series with so much crap that the laptops were slow as a turtle right from a start up. They failed to listed then and lost almost 60% of their market. Others reacted faster and gave the option of removing crapware ( mainly proprietary sofware and trial) when ordering [ btw,of course, anybody could do it by msconfig but few were willing to mess it...].
I can't get it why Sammy, HTC, LG won't offer a barebone/unified Android. We could all get what we need from Market and this is why we have the markets war.
I don't want my update service running in background, nor do I need email app from Samsung...in order to get them off my back I need to root, Edit a file and make sure I mount the right permissions( or BUY something to do it for me) and so on, most people don't want/can't root , not mentioning the longer the chain the more links likely to break, including the warranty is voided ...WHY all the fuss to stop something I don't want?
Microsoft hit the nail in the head with their approach to WP7 (except closing it like Apple). That's because they had to deal with screamers for 20 years and they have a clue about crap ruining an OS.
And yes, I am still waiting to see a dev coming out with a pure Android Rom on whole XDA.... for any device. They all add something to it....a tiny tweak or a tiny thing.
I've not been able to drain this thing since I got it a week and a half ago. I have to say that I like to charge things over night. I've not been able to get the Photon below 40% before I go to bed each night.
I hear that you need to drain it full at least once but my habit of charging things overnight is getting in the way. Should I just let it go overnight one night?
I was under the impression that completely draining Lithium Ion batteries causes more harm than good.
"The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery."

Also, i'm sitting at 46% after 15 hours of normal (for me) use. not to shabby. I should mention i'm running Juice Defender and build 4.5.1A-1_SUN-198_5 from the dev. forums and i'm connected to WiFi 90% of the time.
going to try tomorrow without Juice Defender and see how it does. After that i'm going to disable SPB Shell and see if that makes a difference.
Thank you sir. I don't want to root my phone so don't run Juice Defender but I do use the Data Saver in stock a lot. I usually just listen to a lot of music and look for new stuff on FB, check XDA forums blah blah blah, yada yada yada...
I'll not feel paranoid about charging my phone now lol.
Now with my tablet (Acer Iconia A500) I did root and load a bunch of different stuff. This is my first cell phone though and I didn't want to mess with something that I have to pay a monthly charge for. I know I could but it's my first cell phone lol.
How much are you guys using it? For me, I use about 30min talking, 1 hr heavy wifi use, 1 hr light wifi use (reading), 30 minutes playing with settings, and the rest of the day idle...that gets me to about 30%.
I actually thought that is kind of weak. Maybe my battery isn't as healthy as yours? I've only had it for 5 days. I charge it every night.
I use it for about 7 to 8 hours of music, FB updates/posting, checking XDA, about 10 minutes of calls and so far some Netflix watching just to show off the phone to my peeps. Oh and some picture taking.
I am the same way I hate to discharge it completely and its been very hard. I've went a day and a half without charging before it went under 10%. I will say that I am on Wifi 90% of the time as I have wifi at work and at home other than that its on performance mode so no true bells and whistles. I'm thoroughly impressed coming from the Evo.

Average day for me is about 30 to 45 minutes of phone calls, 80 to 100 texts, few conversations on google talk, 30 or so emails on three accounts and i have trillian running connected to two accounts.
Connected to WiFi most of the time, bluetooth is turned on (not connected most the time) and brightness set to Auto.
I really dont see how this phone is a monster when it comes to battery life, I've actually been getting the exact opposite. I just fully charged my phone and after running for 2hrs and 7mins its down 78%.... This phone has yet to last me for the whole day. What am i doing wrong? I dont have tons of widgets and the only app that im running that might pose a problem is Go Launcher

Is that your screen on time? If that is then I would say that is impressive already. When I had the epic on stock if I use it for 2ish hours screen on time. I would need a recharge. (Got a lot better after using custom rom. Around 4 hrs screen on time before recharge)

Yes, but what's your battery status at the end of this average day? 20%? 30%? 10%?
+1 for an awesome battery!
Sent from the best MoPho
For the past couple of weeks I've been swapping batteries with an external charger one to two times during the course of a day (plus the overnight charge)... Looks like it's time to do some housekeeping...
Edit: used to have battery life like everyone else in this thread though! While at the climbing gym last night I noticed that the thing felt like it was about to catch fire against my thigh - it had burned through about 60 percent of a freshly charged battery in about two hours. I have a nagging suspicion that I neglected to uninstall something (or a few things), and now something non-existent is constantly being polled for as a service after I launch some app for the first time...
when i got my phone it did great on a full day charge, but now with it just sitting at the office its at 70% by 11am i take it off the charger 7-8am .. it started to "weaken" after i downloaded a ton of apps i leave wifi on and 4g off but it also depends on your signal strenght at home it will kill the phone halfway thru the day because i have one bar
Im new to this device and have some problems, I thought removing stock might help, so I've started using Leeroid newest rom but the problems are still there....
- The battery drains quickly, there are on average about 80 task running in background. My last ZTE phone had on average 17 tasks in background. I think this is all because of sense...how do I stop this awfull battery guzzler...?
- I cant find the wifi sleep in standby option, closest thing is the 15 minute shut off option, not good enough... where is the wifi sleep in standby option?
- 3D pictures I take with Amaze Camera are out of sync and shadowing when I look at them in gallery, what am I doing wrong? The stock rom had no problems...
- The battery needs about 2,5 hours for a full charge, my zte skate did a full charge in about 45 minutes...
- The screen 960x540 is good, but everything is tiny specialy the text, how can I increase the text dpi to make the text bigger? In windows I can increase dpi in screen settings, is that available here?
Look up density changer on the market. It will make your text bigger.
Why not just turn wifi off when you are not using it?
The battery in this phone does take a lot longer to charge compared to my EVO. I dunno why though.

Thanks, dpi changer was a good tip, I've increased from standard 240 dpi to 280. That's much easier on my eyes.
There is a wifi off in standby option on all android phones I've used, why doesn't sense have one?
I took the phone off charge a little over an hour ago and I'm already down to 83% just by having sense running with wifi and about 80 task in the background....I'm going to have to get rid of sense, it's ****e...

You should download the free juicedefender or purchase juicedefender ultimate from the market. In there you can tweak settings to disable wifi + data on screen off, as well as many other things. I'd strongly recommend it.

you most deff have a rogue app there chewing your battery down big time. When you say you have 80 tasks running in the background, how are you checking this exactly?
JuiceDefender is not really needed for task killing as android has improved huge in this area and manages things very well. Most of the time users have things like facebook and such set to sync automatically and then claim gains with JD when they block facebook(and others) from syncing except for only X times a day, which 99% time is an option to set in the actual app in question itself anyway.
SystemPanelPro is one of my favorite apps as I run the monitor service in it to better get a pure objective opinion on battery usage as it shows you exactly which things are eating away at the battery right down to the process itself.
You can have 500 tasks in the background and not have any battery drain. Apps are cached and dormant in the background , saving CPU cycles to reopen it and thus actually saving battery. You could be seeing way more apps cached than your old ZTE, because, well, the 3D has way more ram!
Usually its one app thats draining your battery , and most of the time its apps that have push notifications that are not from Google or have a ridiculous default poll time (Like tweetcaster checking tweets every 5 minutes and words with friends checking for new moves every 5 minutes as well). Go through your apps and check poll times.
Wifi should be on if you have access to a good connection, even when the screen turns off. Whenever you turn your screen on, your wifi chip has to wake up, scan, handshake, connect, and restablish connection with all your apps and services... Costs a TON of battery, especially if you are always turning on your screen even to check the time.
And Sense 3.0 roms have the reputation of being very good on the battery, better than any AOSP rom by far.. especially the latest official rom and radio update.. people have nothing but praise about battery life.

-Phone has big battery 1730mAh I think. Your old one was 1420mAh (about 20% smaller) at most that is why it takes longer.
-Usually if my 3D get out of sync (don't know why) I reboot and the problem goes away.
-Use SpareParts+ for Wifi sleep
Phone doesn't charge all that fast because while charging the phone doesn't sleep.
I'll try the wifi off in standby with spare parts plus, thanks for the tip..
Actualy the 3D pictures were fine afer a reboot like you said.
Leeroid was eating up my battery so I'm trying the king cobra rom. Not sure it's placebo, the battery indicator hasn't been going down so fast in cobra...
There's a stock android rom without any trace of sense here in the forum somewhere. I might try that too
I use quick system info, when I clear memory it say I have on average 80 tasks running, after an hour I do the same and again it closes 50 tasks!! I have the same apps I had running on my skate so that is why I know sense's the coulprit.
When I wipred the memory with quick info on my skate with cm7 I only had on average 17 tasks closed...

Sense has a lot of "processes" running but they are not "killing" the battery like you described.
Also like the other poster said, if your in WiFi area leave it ON ALL THE TIME when you can connect to it. its much better than having the radio on 3G all the time, and also if you only have it sleeping in standby like they said you kill the battery everytime you wake the phone up b/c itll try to connect agian as opposed to being connected to it all the time.
I'd look at getting SystemPanelPro and turn on monitoring. its very valuable in the long run as it is not a task killer but also allows you to catch rogue apps if you ever do have questions about battery. Anytime I have battery questions I just turn the monitoring service back on in it and then check the phone at the end of the day to see if there were any apps stuck hogging data or something like that.

As stated before it does sleep and does so fine. you have a rogue app or something else killing the battery like poor signal. I can put the phone in standby and last forever sleeps fine.
you have something likely set to sync often thats killing it in the way you describe.
It is not Sense. I have only ever had HTC Sense phones, and all of them had better battery life then AOSP ROMs, unless the AOSP ROM had almost everything removed and I went anal about data usage. As everyone else has stated, especially with this new OTA, it is a rogue app. Check all your games and apps that use data. I have 19 hours up, 11 hours awake, with roughly 8 hours of those in use and I still have 40 percent battery left. Not to mention I have 14 current running processes and 46 cached apps. HTC did an amazing job with this update, please don't blame them. Listen to those of us who have been using Sense since the Sprint Hero and check your app's!
EDIT: Not cached apps, but cached processes.
To save a little battery, you can go to mobile network settings and uncheck mobile network always on.

Wait what? How long was your screen on for? If you meant screen on for 8 hours your speaking bull****. leaving the screen on lowest brightness and no sim card or mobile network on the phones battery only lasts 6 hours. (ive tried this...)

I didn't say the screen was on. I consider downloading full seasons of the Desperate Housewives over WiFi with the screen off "in use." My screen was on for a decent 3 hours today, while downloading the show and doing plenty of other useless things I have already plugged my phone up for the night, so any info I get now will be tampered. But tomorrow I will get some screenies. I wish I could use it with the screen on for 8 hours. I would kiss HTCs feet LOL.
So, have my new rezound (old D2 r2d2 lost a fight with the driveway) unlocked and rooted, running 2.01.605.11
Display brightness is set to ~25%. Running on CDMA only 3G. Only auto sync tasks are my email accounts, and those are push updates (only get 5 or so emails a day). All other accounts and apps (weather, news, Fbook, etc, are manual updates when opening apps)
Yesterday i charged to full, wiped the batt stats in recovery, ran it dead and recharged to full overnight.
Unplugged around 7am and then gave the charged phone a bump charge to bring it up to full. Turned on the phone right around 8am. In just a shade under 4 hours (only 22 mins of which were screen on time), the phone went from 100% to <20% charge. Phone had signal 100% of the time, no roaming etc.

Suggestions? I just ordered a 3400mh battery, but still, I gotta believe something is WAY wrong here. I really don't want a huge battery that's still just gonna die in 6 hours....
Screenshots of relevant stuff attached
what the temperature u getting
if its not getting heat enuf i mean 45c
ur battery could be not good i guess u replace it
After 15 hours (7 am to 10 pm) of moderate use yesterday, couple texts, a few emails, couple short phone calls, 2 hours of listening to music at the gym, checking facebook couple times and I was at 60% when I plugged it back in to charge it. So something is definitely wrong with yours. Under Settings>Power>Power Mode I have mine set to Normal, I also turned off all animations but have all notifications and auto updates are still active and have weather set to update every hour. Set to CDMA only out of the box too.
Are you playing words with friends? How about any other ad supported apps like Angry birds? All ad supported apps are battery killers even when you aren't using them.

Proz - Screen's been off for like 2 hours now, plugged into a wall charger, temp is 43.2 degrees C. I disconnected it from the charger, and let it sit for 10 minutes with the screen off - temp went down to 40.3 deg C.
I've noticed high temps occasionally, especially if i'm streaming netflix while charging, or running screen at full brightness for an extended period of time. When it gets that warm, and I plug in to charge, the LED alternates green and yellow, indicating overheating, but after a minute or two with the screen off, and plugged in, it cools down and charges normally
kzoo - not really. The only apps I use are the yahoo fantasy baseball, and aldiko reader. The phone still has all the bloat on it, but I don't ever open any of those apps. Also, i do run advanced task killer before i shut the screen to kill programs and background tasks. I then exit out of ATK - I don't keep that process running on auto kill, as I've heard that when you let it kill stuff every 1/2 hour, those processes re open, and ATK kills them again, and that open/close/open/close cycle just chews up battery even with the phone off
i would replace that battery and ask for more info in post ur battery thread too
while only charging the battery should be the room temp'
that look too high

The fantasy baseball app could be doing it. That 71% display usage is high, are you accessing the fantasy baseball app a lot during the day or for long periods of time? And of course Netflix will be a big battery drain too as it takes a lot of juice to power this display for long periods of time. I get the same % display time that you posted on my wifi only Incredible that I play Words With Friends on during the day and my battery on the Inc only last about 6 hours when I'm playing it. My Rezound's display only uses about 30% for 15 hours but I don't play games or stream music or videos on it.
Maybe try uninstalling all your personal apps and see what kind of battery life you get just plain stock.
Edit: Are you connected to wifi or 3g when your doing all this?
I don't think it's the yahoo app though - i got the phone friday, and was dealing with the major drain all weekend. didn't install the baseball app on the phone till monday. No appreciable performance difference with the app installed and being used
also, i think one of my screenshot showed my screen on time - 22 minutes on, out of 4 hours, maybe 10 mins of that was on the baseball app, 5 on aldiko reader, and the rest going back and forth in my settings/app settings to double check that i had all the sync settings set to my preferences (i.e. push only on gmail, lowered brightness, etc)
Yeah then something is not right with the phone. I added some screen shots of my battery stats for today in my last post. With 9 hours on so far today, I checked email about 20 times, made a phone call and got a couple texts and played music for an hour at the gym and I'm still at 84% battery. I'm getting great battery life out of this thing without any tweaks.
cool - i'm going to wait and see what kind of battery life i'm getting with the 3400mh battery. If it only doubles to 8hrs, i'll know it's the phone and not the battery. If it jumps to like 16 hours of usage on one charge, then my stock battery is going to be on a one way trip to the scrap heap
i'll post an update in a few days when my new battery shows up
in the meantime, do you think VZW will give me a new stock battery if I go to the store and show them how hot this one is running?

It's worth a try and asking them for a new one otherwise they would have to replace the entire phone. I had them check my battery on an Eris a couple years ago when I had charging issues with it and they were ready to swap out batteries with me but it turned out it was the phone that was the problem.
The first week I had my 920 I was lucky if the battery was at or above 40% by 12 noon. The 920 is my 2nd phone line and I am using it mostly to learn WP8, to surf the web some and listen to a lot of podcasts, usually 6+ hours of them a day. The past 4 days the battery in the 920 is showing insane runtimes. It is currently 11:30pm and it has been off the charger since 8:00am, over 15 hours with overs 8 hours of audio podcast listening. The battery is currently reading 61%. I originally got the impression that LTE was killing the battery, but that is no longer the case.
I have a Share Plan with AT&T with 2 phones, a Galaxy Nexus (GSM model from Play Store) and a Lumia 920. I use my Nexus as my main phone line, to access GMail and Google Reader (a lot of Google Reader feeds). The Nexus has been off the charger the same period of time and is showing 41%.
For me wifi destroys my battery for some reason I get 15 hours with wi-fi on or 28 with it off
Interesting, mine will usually run for 24-30 hours before hitting 15%, including regular usage. 4G gives it a whack but generally I find similar to other phones, if low coverage it chews the battery
Reading all the doom and gloom of 4G LTE on various mobile phones, after my 1st weeks experience, I was expecting similar results going forward. But, after 2 weeks of use, the battery falls in line with the results you mention. And, with that I am not complaining.
same situation here.
It looks like the phone needs some days to warm up and get long lasting.
Also I see that wp8 is heavly optimized for background task in order to not consume a lot of battery eg: my phone lasts more than 2 days with light usage.
I listen to podcast for many hours and it doesnt affect the battery that much, in fact I'm surprised by it because I know audio playing takes a load on the cpu.
Mine.. overnight without charge or using the phone it drained from 100% down to 35%. BS
Two words: Background tasks.
Make sure you don't have unnecessary background tasks running. I have less than 5 and my battery runs more than 2 days easily.
How do you kill or monitor background tasks?
I had really good battery time of 19 hours the first day of installing the new firmware, then I enabled bluetooth again and it drains like crazy. its hit or miss but people seem to think that whatsapp drains battery. I personally would like to disable LTE (its really slow in my area) and just keep bluetooth that seems to give me 12+ hrs of battery.

You can block background tasks for 3rd party apps in Settings->Applications tab->Background tasks. There is no way to monitor these tasks because WP OS doesn't offer any such capability.
Unfortunately there is no easy way to block 1st party apps and if they are misbehaving (like sync something over and over), there is nothing you can do about it.
Turn on Battery Saver can also effectively kill all background tasks. But that's draconian. I still would like my smartphone do something in the background for me.
Don't forget, the biggest battery drain factor could be your cell phone signal. If you keep the phone in a fringe area, the cell radio will drain your battery very quickly while try to maintain communications with cell towers. This is outside the OS and you can't do anything about it.
I had a weird battery drain the day after the last upgrade. No apps running in the background BAR the movie that i had paused.. I lost 80% without using the phone in a 6 hour period (post charging). After a reboot it seems ok. Perhaps i should pause another movie to see if it happens again....
I must say that I have mine 2 days and the battery drains too fast... I dont know what to do .. Maybe because its new ? Some one can help me maybe ?

don't judge a phone's battery life until a week later.

My battery is pretty inconsistent. MOST of the time it's awesome, and will last like 20-25 hours without needing to charge, but that just makes it especially jarring when every now and then I go to check my phone at 4 in the afternoon and it's at critical, and I have no idea what causes it.
Plus when it does die I have to put it on the charger for like 2 hours before it will let me turn it on.
I found interesting point in the battery life today, if the screen is off, the battery drain is in the range of 3-4% which is good, however, if the screen goes on the battery drops like 15% in just 25 minutes. After thinking I tried to set the screen sensitivity to normal and it solved my problem. I kept the screen on for more than 45 minutes and the battery went down almost 6% only which is good. I still have to test more to give a concrete evidence.

I usually run a battery discharge app Saturday night. Then a full recharge with the phone off. That usually gives me dependable battery life of about 12 hours a day for the entire week. If I forget and not run the discharger I notice it midways into the week when I only get about 8 hours out of it.
AT&T lumia920:
after updating my phone to the 1314 update, my battery life got worse.
I went from 14 hours per day to only 8 hours.
thanks nokia -_-
note: I was not experiencing any connectivity issues on my phone.
let's see how many people here actually have NFC on and Auto-Brightness on... lol
I used the sleep app last night after charging to 100%, and then I fell asleep with it on.
I woke up to find the sounds still going, and when I checked my phone worried that I killed the charge, I found it still had 92% left. That's impressive.
