    I don't know what this will turn into but this original post is meant to be a starting place for anyone thinking they are not getting enough from the battery. I am putting this out there because it should be easier for people to skip to this point without reading all the stuff I did. I won't say what I think the standard ought to be but I'll say I am extremely happy with this Note 4 battery performance compared to all prior devices.
    My Note 3 was fine until they "upgraded" to KitKat. When that happened almost everyone in the forum was talking about how bad it got. I'd go off charge and be at 80% by the time I went to the grocery store and back. Before I discovered GSam (Link below) the Note 4 came out and I didn't have to worry about the 3 anymore. The point is that Note 3 post KitKat almost everyone was talking about battery. Here with the Note 4 it's some people seeing what they consider problems and some people having actual issues and many people happy like I am.
    SO, start from the premise that you are running something, or a number of things, that people who are satisfied are not running. It could be from the thread with the list of things they turned off (link below). It could be a lot of things. It could be a couple apps interacting. The only real way to check it is to look at what each app does. You can probably do it best by using an app called GSAM in the Play store. It'll show you which apps and processes are doing what. There's a lot in there and some of it isn't obvious. Just know that it won't help to assume you have a bad piece of hardware (phone OR battery) that's statistically rare.

    I found GSam when my great battery started going down faster...It showed me that my gut was right. Words With Friends I got to play with my daughter was a juice hog. I tweaked the settings and now it is fine.

    LaTuFu also suggests Greenify(Link below) I don't use ti because I don't need it but it has a lot of stars. Good luck! Now you can go read all the other threads but don't be misled into thinking there's a systemic problem.

    I think I found something for restricting background data usage. That is trivial but what I remember reading somewhere when I googled it is that it was using a lot of juce because instead of waiting for notifications it was constantly polling to see if one was there. (These are NOT the technical terms, just what I took away from it). It reduced the drain but it affects play. It's a flaw in the program. I don't know if it is better when played through facebook because I only do facebook on my PC and I do not have that game thing turned on at all.

    Also make sure you don't have tons of email. My battery lasted only 6-8 hours. My Gmail had over 14,000 emails, and after I deleted them down to 4,000. My longest battery life is 19 hours. Yea!!!

    You know, I never thought about this part. Deleting/archiving Gmail may be very important. Does anyone know if Gmail indexes the email folders frequently if there are messages in there (not archived?). There is a reason archive is a feature. I'll try to find some time to dig around and get more answers on this.

    I suggest Greenify because it is a pretty well known app, and it is a pretty quick and easy way to get a screen shot posted up for other users to check out and provide feedback with.

    It might help for anyone looking for suggestions on battery life to be prepared to post their system stats.

    Here are the screenshots I've been asking for in recent threads. Other users can offer suggestions of other screens if they think it would be helpful.

    Maybe we can get a Mod to sticky this thread so we don't keep getting eleventy-five battery threads a day in this forum.

    Suggested stats to post for review:
    Let's start with:

    1. Screen shot of your Power Saving Main Screen

    2. Screen shot of the history screen (access it by clicking on the line graph in the middle of your power saving screen.)

    3. Download and install Greenify. Take a screenshot of the list of apps that it recommends for hibernation.

    4. Take a screen shot of your notification panel pulled down, so we can see the brightness settings you have set up.

    LaTuFu, thanks for helping sort things out... I am trying to determine if my new N4 is misbehaving.... First I have never seen on anyone else's screen shot of battery show 'index service' like it shows on my screen shot below. I also turned off the air wake command, restarted my phone and yet it still shows up.... Any help would be greatly appreciated!

    How long have you had your phone? The index service, iirc, is something that only runs periodically--but it does run for quite a while when you first get the phone. It's one of those items that causes the first couple of days to be worse on the battery. If you transferred your SD card over from a previous Galaxy phone, it is probably ripping through all of the files on the card to index them for the new phone. It should settle down in a day or two after it has ripped through your library.

    AirWakeUp is something you can disable under the accessibility settings.

    Okay. How long have you actually owned the phone is what I meant.

    As far as playing words with friends, that can eat battery, too. What is your screen brightness set to? Can you post that screen shot?

    I got the phone a week ago tomorrow (Sat). My guy at Coscto 'did' take my SD card from my Note 2 and put into the Note 4. I did turn Air Wake Up, Off.....restarted phone and it still shows up in the battery stats, as well does the 'index servicing' so for a week?

    I like the screen brightness pretty high and did have it at at least 75% the first few days, but lowered to about about 50% or just under yesterday.

    How much stuff did you have on the card from your Note 2? I had 1,000 pictures +/- from my S4, and a couple hundred mp3s. Not much else, though.

    A week is about as long as I would expect, unless you've got a few thousand pictures.

    I'm actually planning to sit down this weekend and archive a bunch of these photos onto a flash drive. I just don't need to be carrying them around on the phone.

    Yeah, your screen brightness is set pretty high. Not that there is anything wrong with that, but if you're playing a lot of Words with Friends and surfing Facebook with it set that high, you'll definitely run down the battery pretty quick.

    More bright=more battery

    Well, just looked at my gallery on Note 4, pictures maybe around 600-700 and around/just under 50 song files. All pictures and songs are there on my phone so it should be done 'indexing' they were all there right away......i'm not that techy on how that works.

    I basically play words with friends once in the morning and sometimes once in the evening with one person. I did all the same stuff on my Note 2 that was close to 2 years old when I switched a week ago to Note 4 and note 2 battery held up waaaay longer.

    It might. At this point though, if you don't want to go that route, maybe trying to do a cache partition clear would be the next thing to try. Not as "start over" as a factory wipe, and it might do the trick.

    Make sure your email sync is set to Push, not to a specific polling time, unless you get emails constantly. Push means that your email app sleeps until the email server wakes it because there's an email for it.

    Looking at the battery stats, press the graph and you'll get the second page (see post #7, the part labeled 2.) The Awake line should be almost all blank when the phone isn't being used. You'll notice that when LaTuFu's screen is off, there's almost no Awake time. That's how it should be. If your Awake line is active when the phone isn't in use, Wakelock Detector (see Wakelock with non-rooted KitKat) will tell you why - which apps are waking the phone. Greenify can stop that, so can freezing or uninstalling the apps.

    A side note: Try to never let the battery get below 40% before charging it. Carry a spare battery. A battery and charger (so you can charge one in the phone and one out of the phone at the same time) are about $20. This will give you the longest battery life. (So will conditioning a new battery - fully charge it. Use it until the phone tells you to charge it. Do it twice more.) I have some 10 year old batteries that I still use in my spare "who cares if it gets lost or stolen" phone (it would cost about $15 to replace the phone), and I still get almost full life out of them. Some people post here that their battery is shot after 6 months. How you treat them does make a difference.

    I have never done this before and had to look up how to do it.....like this, I found on Verizon..... Boy I hope I don't mess this up! This won't void my warranty will it?Wipe Cache Partition - Samsung Galaxy Note® 4

    [Device-Specific Instructions]
    Performing a wipe cache partition removes any temporary files that may be causing an issue with the device. All personal files and settings are not affected by this option.

    1. Ensure the device is powered off.
      If the device doesn't respond to input, remove then re-insert the battery.
    2. Press and hold the Volume Up button (located on the left edge near the top) and the Home button(located at the bottom in the middle).
    3. While continuing to hold the Home and Volume Up buttons, press and hold the Power button (located on the right edge) until 'RECOVERY BOOTING' appears in the upper left then release all buttons.
    4. Select wipe cache partition.
      Utilize the Volume Up/Down buttons to highlight and the Power button to select.
    5. Select reboot system now.
      Option is highlighted, utilize the Power button to select.

    Rukbat, thank you. I am currently using stock email and there is no option of 'push' I had looked for it prior. I also use a Gmail account (have not checked that one) I did try to condition the battery as you stated. Screen shots attached. Thank you to you both for trying to help.
