I've noticed what appears to be excessive battery drain while left on overnight. My phone went from 97% to 70% This phone should not be using this much battery while in standby mode. Display consumed 37% of that 28% even though it was off all night. Anyone have any ideas on what this could be.

I usually lose around 2% overnight and I always have wifi on..Download cpu spy from the market and make sure its going into deep sleep..
Also try betterbattery stats app and see if you have a rogue app causing a wake lock or something.
its not going into deep sleep, as is evident by it showing it being awake with the screen off. do you charge via USB or car charger? there is a big that prevented it from going into deep sleep. if you use a wall charger the issue is not there.
I did download CPUstats already and the phone is not deep sleeping correctly. I will try the second app you mentioned and see what's causing the wakes. Thanks.

I have the same response as MR.DSL
I have noticed, since I did a deep cycle of the battery, it has started to maintain better % overall.
Biggest drain is driving with music from over the air, and navigation running.
Hence, I use battery backup for driving.
Love this phone. They just keep getting beter each year.
I have the same problem although i have the problem only when flashing tpc's Rom. And i don't have my gmail account logged in so therefore i shouldn't have any background apps keeping it from deep. Although when flashing back to stock.. I have no problems.
Just got my note yesterday and notice there is a similar problem this morning. With wifi on but sync off. The battery dropped about 15% in 6-7 hours without any usage.
Then I remember when I was using other android phones (streak 5, desire z) when I use GOOGLE Latitude it drains my battery almost continuously. Just log out the Latitude to see if it gets any better.
it is the deep sleep... before I started rebooting my phone every morning after it was charged to 100%, my note could last merely 13hrs.... since I started rebooting every morning, it lasted more than 18hrs and still had ~30% of battery.... and battery watch shows I usually have 50+% screen on time and wifi always on
So after resetting my phone and reverting to stock kernel. My phone dropped only 3% over 7 hours. It was in deep sleep 97% of that time. I'm hoping it continues to behave this way.
Sent from my SAMSUNG-SGH-I717 using XDA App
how does one find out if the gnote is going into deep sleep mode or not, using the "cpu spy" app? does it tell you right off the bat or you need to correlate it with something in order to determine if it is or not? i'm having the same issues with my battery life dropping significantly over night. i tried restarting my phone this morning after i disconnected it off the wall charger. i'm at work right now and the battery life is still dropping fairly quickly, after i had already killed all the apps before turning off the screen...
edit: i'm running on stock kernel and have not rooted yet..
is your phone rooted or not if so what kernel are you running?
Sent from my SAMSUNG-SGH-I717 using XDA App
So is this issue only present in rooted devices? If so i think ill just flash the stock back on and wait for ics.
Sent from my SAMSUNG-SGH-I717 using xda premium
That's what I'm trying to figure out. If anyone is having this issue while running a rooted kernel, try flashing stock kernel to see if it changes anything. Either way please report results.

How much screen on time did you have? how long has it been since you flashed your current set up?
Sent from my SGH-I777 using XDA App
sorry forgot that shot....i rooted and flashed on either Sunday or Monday this week.....now i do use bluetooth for work so i'm thinking that kills the battery big time....
That is kind of good battery life considering you got almost four hours of screen on time. If your really worried then you should get one of the 3500 mah batteries. I have this one http://forum.xda-developers.com/showthread.php?p=21589969. This battery gets me through at least a day and a half of heavy usage, and it works great for the price.
yeah i wasn't sure...i always keep reading about people getting 1.5-2 days on a battery...it's a new toy so hopefully when the excitement wears off that screen won't be on so much
That's exactly what will happen. You have new phone syndrome. I did too, when I first got my Galaxy S2. Except that I, unlike you, was running stock unrooted, and my battery life was more like 8 hours. I'm now running stock rooted with Entropy's kernel, plus I don't use my phone as much, and I get between 15 and 20 hours.
Sent from my SAMSUNG-SGH-I777 using xda premium
Yeah...with almost 4 hours screen on, and mostly on cell data (assumption based on your 2.x hours of wifi on) that isn't too horrible. Your total awake time is about an hour more than screen on, so assuming you had phone calls, music playing, or some other screen off background task to account for some of that, you're doing pretty good...

LOL so I'm guessing the best way to really conserve battery is to keep the screen off. Just outta curiousity (which I will test tonight after full charge) what is an acceptable drop rate when phone is fully asleep for say 8 hours or so. Like what 1-2% an hour?

I think the best I have seen reported is 0.5% per hour. Mine on wifi has been as good as about 0.8% per hour, but usually a little over 1%.

2%/hour idle drain I consider bad - that's why I haven't released a kernel since 1/2/2012 - I have a power management regression that pushes drain to a bit over 2%/hour when connected to wifi.
I strive for 0.5%/hour and get very close to that frequently when in a good signal area. In a weak signal area (like at my desk at work), it's around 1%/hour.
4.5%/hour or so is the idle drain you'll get if the phone is unable to enter deep sleep.
My rate of battery loss is insane. I can sometimes lose more than 14% an hour while using it. That's with cm7 and the extended/fat battery! Is this normal for heavy use or is there something inherently wrong with my phone.

My brightness (in a profile) is set to 15% and I run that 24/7 unless I'm outside making a phone call or something to see the screen . . .
Could be the antivirus. Have you tried battery calibration by nema? (In market) I'm running infected and using the same battery (OEM right?) And I get about 5% drain an hour with 4g on and screen on about half the time. Sometimes more or less depending on usage.

Doesn't that just clear the batterystats file on the Sd card? That doesn't affect use unfortunately.

I could be wrong, but isnt juicedefender an app constantly running? Have you tested your battery without that app?
Sent from my ADR6400L using XDA
First off thanks, I now feel better about my battery life. in my opinion battery life depends on a lot of things. Juice defender didn't seem to play well with my phone. I only turn on wifi when I need it. Also I would charge to phone to 100% and reboot into recovery and clear the battery stats. Not sure if any of that would help, but it can't hurt to try.
I've noticed a bit more accurate readings when resetting battery stats, which is why I suggested it.
Otherwise, you could try a complete backup of all your apps and trying a different rom?
My battery lasts about 14 hrs with regular to heavy use. 11 hrs on the fat battery seems like its way too low. Have you rooted and unclocked?
I would unistall juice defender. You can set up the phone just as well without it and have one less app running (which uses battery)
I have an avg of about 12 hrs fully cycle since i bought my phone over a year ago. I have to make sure that all the setting (i.e. GPS off, wifi off, screen turned all the way down) are always correct to push anything past the 12 hr mark.
Your best bet is do like the rest of us and make sure you have a charger always ready if you are ALWAYS using it.
So since I can't get a hold of my phone right now, I'll explain with an illustration done in Photoshop

My battery graph goes a bit like this.
As you can see, the first green segment is the normal drain rate while my phone is in deep sleep. Say, if I restart the phone, and just leave it to sleep without touching it, the graph would go down at this rate. This rate is pretty good for me, usually a 1% can last 4 hours.
The blue segment is the drain rate while browsing with wifi. The drawing is only an approximate illustration, but needless to say this drain rate is much faster than the green drain rate. I can get 5 hours with wifi browsing, with equates to 1% every 3 minutes. It's not too bad I think.
The problem here is, after browsing (or doing anything) over wifi, the battery curve would go weird. When I'm done with browsing, I always turn wifi off. What I would expect was that the battery curve would immediately return to the normal deep sleep drain - the green line. And yes it should, because as CPUSpy shows, the phone deep sleeps perfectly. But the graph, instead, shows something of a "transition" curve - the red one as shown in the illustration. The drain in this period isn't as fast as the wifi rate (blue), but it is faster than than normal deep sleep drain (green). Only after some time will it return to the green rate.
So...what is causing that red curve?

Yes I did, but I thought having a wakelock would take away from deep sleep time? I usually wipe my CPUSpy stats and leave the phone to sleep for an hour, it would almost always come up as 99% deep sleep. But anyway, I did check again, and RILJ was at the top of partial wakelocks, at 16 mins after 16h. It isn't seem to be adding time though.
Why two threads within half an hour ? They're essentially about the same thing. You could easily have edited your OP and/or title in the thread you created ~26 mins before this one :-/

Dunno why CPUspy is reporting wrong, but the rilj wakelock was for long, hence the battery drained more. If you're looking for a solution, what I've read to solve that wakelock is to turn airplane mode, switch off mobile, switch it on and then turn airplane mode off....

Anyone else seeing issues with really inaccurate battery readings? I'll be at 99% charged for 15+ hours sometimes, and then things will drop rapidly or even just die at 20%. I've also noticed when charging that it'll get to 99% within an hour or so and then spend 30-45 mins at 99%.
On top of this, my phone battery just died at around 55%. Are others just draining their battery all the way to try to calibrate?

What rom and Kernel are you on. Also what mods if any such as battery indicators and such have you put on your phone?
@dragonstalker: I'm running stock with the latest OTA update. I'm using Batterybot to display the indicator in the notification bar, but the reading is the same from the stock battery display.

Doesnt do anything for Li batteries its fud.
For the last 2 days, my battery has drained overnight and is dead by the morning. The first time, I didn't think of it. This time, I looked at the history and it drains within maybe 6 hours without the screen on, being awake, or anything. I turn off all of my radios besides cellular at night. So I have no clue what could be causing the battery drain. Any ideas? Here is a pic of the history

Is anyone using battery calibration apps? I know some of the custom ROMs like Hatka Supreme list that they include some sort of function in those regards.
I thought even on stock there was a way to erase battery stats so that you could recalibrate. No? Could of sworn I had seen the option when I first got the phone. Could be wrong too...

I downloaded Gsam and it says that my radio is taking up most of my battery. Any idea why this is happening because its never done this before? I used to get at least 2 days of battery usage. I charged it until it was full yesterday, let it sit overnight, and this morning it was @ 20%. I'm on newts M7 and z's B5.4. I've been on this combination for the majority of the time I've had my phone an no problems until now. And I don't think its the kernel because the same thing happens when I had it on 5.1. I noticed I was on global mode and I changed it to LTE/CDMA. Who the hell knows, that might be what's causing it. We'll see. Any help is appreciated.

Using the battery app see what app or service is keeping your phone awake. That would be my guess as to what the problem is. I would also suggest flashing cpalmers kernel as well, which has been really good for me in limiting awake time.

Install BatteryGuru, give it a couple days to learn how you use your phone, and watch how it saves your battery once the learning period is done. I swear by this app, it brought me from almost a day to about a day and a half as far as battery life is concerned.
I installed the Gsam battery, it shows that "phone radio" was sucking down a vast majority of the battery.

Then you must be in an area where service isn't good and your phone is searching for service which kills the battery quickly. To conserve battery turn on air plan mode and then turn service on when you get into a zone with better coverage. This will help your battery a lot.

My opinion..don't install any more apps than what you only use. You install more apps it will obviously suck more battery. What you do. Root/unlocked the bootloader and install a sense 5 4.1.2 base Rom. I came from stock and since I've installed a sense 5 stock Rom I've notice a big battery saver comparing from the original sense 4+ stock.hopefully that helps.
Thanks all
Strangely none of this helped the battery drain is too high in standby, after resting (no apps installed only stoke apps) and even flashing sense 5 rom still 15% per hour and even in Air plan mode . The strange thing during the use of the phone the drain is normal.
