It sound like you have a faulty battery if it only lasts three hours, I think you would have to be gaming to flatten a good battery in that time.
John.
Mine is the same. If I'm browsing the web, using instagram, Facebook and receiving email my battery will go from full to empt in easily 3 to 4 hours.
Backup, factory reset, reinstall apps from market (try to install only the ones you use a lot at first), restore the data you need. If you're still seeing the same things happening, install a battery logger / system logger. Use this guide to see if there's a rogue app that's causing the trouble: http://forum.xda-developers.com/showthread.php?t=937080
If it's still acting up and you cannot identify any unusual drain, I'd ask for a replacement.
After you get things sorted, you can use apps like Juice Defender from the Market to prolong your battery life even more.

thanks guys for the sincere contribution.... i hope your advices help me...
my top battery consuming activities are:
temple run
google play
msging
go launcher
and nothing else
gaming and browsing certainly make the battery drain almost visibly..
things above and beyond the above to try include..
1. reduce screen brightness
2. reduce frequency of or disable background updates by apps
3. no vibrate notifications
4. work more, play less!..lol
the battery life of the Note is great, unless you use it .. a battery monitor will allow you to see the battery drain over time..this will help when you address item #2 above.. if you accept default refresh times, and have lots of social apps your battery can die in 6-7 hrs without even using the Note at all!..
I really love when people give the tip to not use your phone as a battery saving tip

some hints for better battery life
Got mine the other day. First charge battery was fine. Second charge went down 7% in about 5-10 mins. Then it restarted :/ Came back on, down to 88%. Turned the phone off as was frustrating me as it restarted 3 times yesterday. But when I turned it back on I was at 83%?
Hasn't last me the day, it's on charge now. When it pops up telling me to charge it tells me to shut all apps and that using while charging may effect it charging. Is this correct? I didn't think it would have anything to do with it?
3 to the 4 hours continuous use is normal... Only if your phone is standby and then depletes in that time You should be worried. I recommend researching wakelocks in that case.
There are many variables that can atribute to batterylife depletion. Eliminate those first and you will have your answer.
I had best results on stunner version 19. To bad it has the death kernel (leaked ics)

I am facing a similar issue, facing a massive wakelock by PowerManagerService. It keeps the phone awake all the time?
Any suggestions?

Usually that wakelock is there cause you are charging, or have USB plugged in

Had the note for 2 days. It came with LA4 FW and updated via Samsung Apps for the latest FW.
Battery drain, that was none on LA4 became very strong!
Installed Better Battery Stats and discovered that the CPU was always running.
Factory reset solved it...

I can recommend "2x Battery" free app. I'm using it today and making a very noticeable difference.

Im Totally stuck and had my OTA to 4.3 and now i see alot of battery draining by different apps.. now Phone idle is totally eating my battery more than every thing else !! even if i put my phone on airplane mode it has its effect ! what should i do with it ?!
Expect ALOT a battery drain for day one with the OTA and then it will stop draining badly, it is restoring some data using Google Backup and such at the moment.

Hi guys merry Christmas,
I haven't rooted my phone or anything but for 2 weeks now I have that mmc0_detect wakelock.
I'm losing over 10% overnight with the airplane mod on.
When I check the battery stats android system is at 51% and android os at 15%.
I've downloaded better battery stats but since I'm not rooted I can only see kernel wakelocks.
Cpu stats shows that my phone still goes to deep sleep.
I cleared caches and yet it's still here.
I'm not sure how to fix the problem.
Did anyone had an idea?
I found on an Italian website that it can be caused by a faulty sdcard.
But since it's impossible to put one in, the problem remains
I have 20% battery drain overnight (8 hours). I just got used to it lol.

Yeah but that's not normal. Have you tried better battery stats?
I am having this weird high android os battery draining problem...I have nothing syncing, no gps, and using greenify. One charge cycle I would have superb battery 10 hours on screen...then the next charge cycle I would have high android os battery draining problem double the percentage android os (40%) compared to on screen.
I have wake up detector installed and nothing seems suspecious....but I have like greater than 40 percent awake!
Thanks in advance for help

Use BetterBatteryStats to track your every movement, and which processes are being run. These are categorized by how long each process is being run.
In my cases, Android OS usually meant it was indexing my microSD.
How do you stop indexing?

You don't. Just keep it on charge and do a reboot. It will auto index and you'll be charging on the way.
normal or not? 80%. after 10 hours.

I've been getting huge battery drains with Android System and Android OS taking up about 32% of battery life the past 2 months, with no big change in my apps or usage. Seems to even happen in flight mode and screen off....I'm starting to fear it's some google app that broke for our phone, trying to find the cause using BetterBatteryStats ATM.
I encountered 22% Android System usage and it's draining my battery. After a full charge, it takes 10 hours I didn't touch my S3 Neo and the battery is 72%.
I don't know what is the problem. Because the OS should work transparently with minimum CPU and battery usage.
