how do you make your phone go into a deep sleep?

ive seen people saying about deep sleep how do you do it? sorry for a noob question.

It's automatic. When you lock the screen it should go into deep sleep. Download cpu spy to check cpu states

so basically to save you battery . should i use JD?

No need to use Jack Daniels to put your phone into deep sleep. (I dunno what you mean by use JD lol)
Most ROMS, including 100% unrooted stock will use deep sleep.

^^^^^^^ - Bahahaha!
I read the Thread title and started laffing immediately.
========================
Just smash your phone against a wall to make it go into eternal deep sleep, mate.
========================
I believe the chap means 'Juice Defender.' Make sure you don't have apps keeping your phone awake, too.

Right, deep sleep is a battery saving state when phone is not in use. JD makes a smartphone dumb by disabling the radios. It generally uses more battery than it saves. I don't use, nor recommend JD(Have tried it though, and quickly realized it ruins a smartphone and makes no difference in life). However, some people still seem to think it's some great gift from God, but they are mistaken. A simple script to UV and UC/OC can take care of all your battery saving needs. Or if you can't manage to run a script use system tuner to do these things.
If you are planning on running an ICS rom you cannot not UV or OC until kernel source is released, though. You can UC it

Turn the power off lol
Nah I usually close all apps and cached ones as well. No oc UV apps either

Is there a special way to close those apps??

Like this:
Settings > Applications > Running Services.
Press Menu, and select Show cached processes (you don't have a choice, really).
Now select whichever processes you want and stop them.
Say, M&S, is it ok to stop ALL of those cached processes?

[q] big battery problem please help!!!!

No matter which ROM i choose wether its 2.3 based or 4.0 based, Calks or Phantom. Even CM9, Team Dirt. I always get crap battery life. ANDROID OS and ANDROID SYSTEM hog the battery!!! Why is this. The only thing that has not changed will i have been flashing all these roms is the Modem. I am currrently running FF18 Modem. Could this be the culprit? Please help guys!

The android os usage in ICS is normal. What do you consider bad battery life?
So many things affect battery life. Low signal will wipe out a battery in no time, synching multiple accounts (email, facebook is notoriously bad...) and software you may have installed. How is the battery drain when the phone is sleeping? Since there really isn't much we can do about battery while you're actually using the phone, the next step is to improve on sleep efficiency and this will help the battery life overall.
Try installing BetterBatteryStats. There is a thread here on XDA you can search for and download and install this app. The best way to use it is to let the phone sleep on battery without using it for a minimum of 2-3 hours, overnight is best. Then view the kernel and partial wakelocks to see if something isn't allowing the phone to sleep properly.

battery battery life?
Couldn't you also use multiple profiles in an OC app to undervolt and underclock the phone when it sleeps? (screen off profile set to 800MHz and screen on 1200MHz) Just a suggestion, hope this helps.
I have to charge my phone twice a day because I am on it all the time. My ave battery life 11hr 47min. Running Badass Battery Monitor.

Turn off auto sync for your Google account on your phone and manually sync it from time to time. Before I did this android was at the top of the list in the battery. Now screen time dominates everything else in usage.

Yes I did this too, it helps a lot

Yes, synching too often is a killer.
Don't forget about the phone radio too: wifi/bluetooth/gps/data/4G all can have a negative impact if left running.
Someone recently posted that at his workplace, he had zero signal and he could barely make it through the day. He discovered turning data off entirely in that scenario saved battery in a huge way.

They often drain more battery toggling data on/off constantly than just leaving it on. And of course you get no push notifications when data is off...

Works well
Hi All,
I have installed the Juice Defender Plus. Since the first day of the installation, noticeable battery life improvement was seen.
Indeed, if u keep your data OFF (this consuming the most power) then...I can say that u do not need Juice Defender.
However, if u prefer an application to manage these settings automatically, instead of manually enabling/disabling data, then I recommend the use of Juice Defender.
Also, the application has a lot of settings that can be customized based on your needs.
I have it for around 6 months and I am still using it. I am stock...no root, no nothing
Hope this helps.

I mostly agree with this.
It really depends on your usage scenario though. If you don't use your phone a lot (or wake it frequently) during the day (and don't mind being 15/30 minutes behind on emails and other notifications), apps like JuiceDefender may potentially save you a bit of juice - if configured reasonably. I used to use JD a lot, and used to argue for it quite passionately. At some point, I stopped (I think I just forgot to restore it after changing ROMs) and I realized that I wasn't really using much more power during the day - and I was able to get real-time push notifications (rather than waiting every 15/30 minutes for JD to allow it). Now I just use Tasker to intelligently manage my device's radios under certain situations and my phone has no trouble making it through the day.

Eh no. It's the same or worse.
Plus I hate how I have to wait for data to reactivate.
--------------------------------------------------
If I have helped you.... hit that sexy thanks button. ^_^

I used to use it and it worked great. Battery life was great but my "smart phone" was not so smart as I was often not notified of any emails or data related content.
I mean you have such a powerful phone and I'm sure that is why you got it... why limit it? just a thought.

I started using a widget for my 3g. When I tried JD on PA sprint it slowed my 3g for some reason. I'm sure I could test it more. Or I could try not to be lazy and use the widget.

What's your screen on time.

Looked kinda like liteflow might be causing problems?
Cell Standby i think is the one that is coded wrong and is lying, ignore that one.
If you press Android System in settings, battery it will show you the top components being used
Also in dev options look for and check Show CPU Usage. It will show whats using the cpu in the top right of your screen. Watch for what stays in the top few spots in the list.
There may have been something that didnt like the update. Try first uninstalling apps and if that helps reinstall them clean, no data restore. If you continue to have problems backup all data and factory reset. Start clean.
If all else fails use odin to flash the full LH2 fw.
LH2 should be a fairly stable build. Most have no issues and many get outstanding battery life. Im willing to bet its either an app or the way you updated or both.

That's really not THAT bad for a screen on time. I saw your screenshots in the OP, and you were down to 80% in only two hours of being on the battery, but you had the screen on for almost an hour of those two hours; 20%/hr for the first few hours is pretty normal. It's not stellar, but I wouldn't say it's an epic drain that being said, I'm sure you could squeeze some more juice out of it, and prob is just an app causing more drain than usual.
Also when doing a screenshot, it helps to hit the power button first, then the volume, so you don't get the volume pop up every time.

48hrs later.......

And I am pretty disappointed in the battery life of this thing. I used a htc one for a few months and I actually think it did better than this beast. I got to say though, the display on this thing kills everything I have ever used as far as the enjoyment from the massive size. But when I was looking into this thing I kept hearing 2 days easy with this guy. I am at 23% at 250pm when I took it off at 630am. Is there something I have set wrong or is this typical. My htc would be at 25-30% when I went to bed at night usually. I do have automatic brightness checked just an fyi because that is the first thing people will prob ask.

I can't comment on the original battery because I ordered a 7960mah battery off ebay the same day I bought my Note 2. I take off at 6:30 am also but my battery is at 73% and it's 3:28 pm. I knew I was going to abuse my battery so I replaced it before it even had a chance to let me down lol. Also, I'm running Paranoid Android 3.96 (Android 4.3) which is one of the custom roms that gets good battery life.
Wish I could be of more assistance?? Well here you go.
1) Disable daydream in your display settings
2) Flash a custom kernel for stock roms...I would suggest Saber or Perseus
3) Download STweaks after installing a custom kernel and perhaps underclock your processor to 1.2 Ghz, you shouldn't see a big difference in performance but should get a HUGE savings on battery life.
3.5) You can also allow your device to go into a deep sleep at 200Mhz while you're not using it. It's kind of like having your phone completely off but will instantly wake when you get an email, txt, etc. And afterwards after a user set time, it will sleep again until either you wake it or get another message.
4) Last but not least, if you really want to tweak your stock rom into tip top shape and aren't comfortable flashing alot of mods...download Pimp My Rom from the Play Store and let this app do the work for you.
Hopefully some of this will help you out.
**If you one day get familiar with flashing custom roms, this will be a huge savings on battery. I would recommend 4.2 roms or 4.3 roms because they aren't bloated with alot of the Sprint/Samsung junk that is running in the background, ultimately killing your battery without you ever knowing it.**

I can't really say if the kernel affects the battery life that much, unless your underclocking which am overoclocked and still get great battery life but as of the smoothness saber kernel is great for me.

You fail to show your screen on time. You probably have like 3hrs worth and at 55% for all we know. Which is what I actually get from this bad boy before I hit the 50% mark. On a good day I can get 6.5hrs of screen on time and I have lots of stuff syncing in the background.. 3 email accounts, Google services, Weather, Facebook, Samsung account, Skype, Tango, Twitter, ubersync, Voxer, what's app, YouMail and fring.
By the way did you get a brand new note or did you buy a used one? Battery could be faulty or another thing could be you are in a bad coverage area which drains batt.
