Galaxy Note 4 Battery Rapid Battery Drain

Hello, I purchased a Korean (I live here atm) Galaxy Note 4 about three weeks ago and have been experiencing extremely rapid battery drain.
Initially, upon unboxing I noticed that I'd get about 2 hours max screentime with 3G browsing usage before the phone would power down. As a result, I brought it to the Samsung store in Seoul last week and they gave me a new battery. However, the new battery appears to have changed little, though I was getting up to three hours screentime maximum afterwards, so that was a marginal improvement.
Yesterday I did a factory wipe and reset the phone, deleted all the unnecessary apps, and reinstalled just the basic extras one at a time to see if that would improve things.
Today I took it off charge and noticed the drain is still noticeable. When browsing websites OFF the charger cable I see the power drop by 1% every 3-4 minutes. Is this normal? I calculate I'd get between 4-5 hours of power at constant browsing at this rate, which would be fine if spread over the day, but the other issue is that even on standby the battery usage is noticeable.
Even following the factory reset I notice that besides from the obvious "Screen" power usage, "Android System" is one of the biggest drains on the battery. Currently it is using between 25-30% of power, and if you look at the sleep log on the battery (See attached) you'll notice it waking lots even with screen OFF. So it seems there are some extremely battery intensive processes that are going on all the while in the background. And when I click on the Android Services battery breakdown, I get about a five page list of processes that are running (also attached), which really does seem excessive for an operating system alone. Could it just be lots of network installed bloatware?
Unfortunately, Samsung told me that past Monday I'd have no chance to bring the phone back for a refund, so now it seems I'm left with fixing it myself or selling it.
As a Note 2 owner who relied on the great battery life I am very disappointed with this.
I'd really appreciate any suggestions for getting to the bottom of this -- or figuring out if there i simply a hardware fault at play here.

Here is the long list of Android System processes I've got running:

Root your phone and control your awake events by App Ops, Amplify, maybe Greenify.

Bloatware sucks. I deactivated almost everything and it works for the moment! But root will be the only way to get more Performance. S health for example i a battery drainer....

Thanks: how many processes are running in your Android system now you rooted?
Is this the solution? Because obviously if I root, then it makes getting an exchange even more complicated..

Can you tell me how to take a large screenshot? I will post u the process list. My device is not rooted. I will wait to be sure that my hardware is ok.

Thanks. I actually had to make that in Photoshop. It took five individual shots.

Quick update at end of the day.
13 h phone on with 3h45 screen and I'm left with 3% battery.
Is this really the best a thousand dollar phone can do?

Chad you have to many apps in your notification bar! Check this apps pls if they are running all the time. Is this a snpadragon device? Display @ auto brightness disable all nfc / smartstuff

That's what i disabled [emoji6]

Not sure what those apps are as they are not visibly running.... i feel the issue may be related to the sheer amount of bloatware the korean providers bundle into the system...
Is there any tool to do an optimum battery test so I can figure out if it's software?

Wakelock detector but u need root.
Dude go to appsettings and start disabling all that bull**** my phone is good now. Check every app an decide to use it or not.

My note4 SM-910L from LG+ korea too
And this is my battery stat
As you can see i use airplane mode all the time. Only use wifi and battery still good ( play shadow fight, ppsspp ,... ) and sot can reach 5h easily.

Sync takes up a lot of battery

Yes but deactivating all services of a device takes all the features u pay for.
I got up to 5-6h display time on my 3rd charge.

Well, I'm in the Samsung Service Center again and they just updated the build of the OS, slightly different one although it's still 4.4.4
He said that would fix it, but I spent fifteen mins in the shop after getting it back and battery drained 5% already.
Yet all his diagnostic tests are coming back fine...
They're taking another look at it now, but I'm not particularly hopeful of a solution.
And as someone is suggesting: what is the point of buying these new devices if you only have to disable 95% of functionality to get decent battery life?
I'm convinced there is a hardware issue at play in mine, my two year old Galaxy Note 2 gives about 30 % batter than the brand new note 4; that can't be right!

Same problem here
Hello there i got the same problem with my rooted sm-n910k and i installed amplify and now i can see where is the battery drain . I got battery drain from :
Service Name :
com.sec.android.app.soundalive
Wakelock :
RILJ1
I will also atach some pictures to find out if you got same problem like me

I have the sm-n910k too (Korean standard one).
Since going to the shop nothing is better.
Today 14 hours of power, with about 2.5 hours of screentime (not web browsing, but mainly s-note stuff).
Is this really it?!

Is Is it because the SM 910K (Korean version) uses a different chipset to rest of the world that the battery is so poor?
The guys in the Korean Samsung Service center shop told me that the battery life I am getting is NORMAL.
But look at the attached screenshots: <13 hours. Is that really normal? If so I am very, very disappointed...

Phone gets warm and battery drains after 7.0

It used to be the most amazing phone, with the most amazing battery
Now after updating to 7.0 I have a battery drain, instead of 4.5-5.5 hours of screen on, now it's 2.5-3 tops. Also, the percentage sometimes skips number, like 89 straight to 87 and so on. And if that isn't enough, phone gets to 39-40 celsius simply using Chrome for ten minutes. It shouldn't be like that.
What to do?

Give it a few days so that system can settle.

Is doze not working for you either? See: http://forum.xda-developers.com/nexus-6p/help/doze-gaps-battery-graph-doze-t3449618

Also, did you do a full wipe after updating?

I haven't done a full wipe but I have reset the phone. As for the doze, I have no idea but I lose more battery while using, brightness is at 30% but it takes 1% of battery each 1.5-2 minutes.

Initially after updating this wasn't happening to me but it just started, my phone gets warm after short use and battery drains quicker now.
I haven't done a factory reset yet, I was waiting for factory images to drop and just do a fresh install.
This happened to me on the N5, performance dropped after going to 5 from 4.4.

Do a factory reset. Problem solved.

Battery Drain Advice

Battery life on my S7 has been terrible lately...not even rooted. Any suggestions?

I've tried a lot of different things. As of late my battery life on stock hasn't been to great maybe lasts 8 hours. Only way for me to increase would be to run in powersaver mode and manually keep the screen brightness low which I don't like to do. Seems like the battery life just deteriorated for me over time. I have a lot of services disabled and auto sync off. Been Contemplating getting a battery case. I also have greenify installed. I do notice better battery life when Facebook and messenger isn't installed but the alternative apps for them for me just don't work as good.

I can get 2 to 3 hours screen on time rarely 4 hours. Unless I do the power saving and manual brightness.

Make difference b/w fast charge vs normal

Through my experience, I seeing extra hours on sot or standby for normal charging. And for fast charge, charge is fast but drain also fast. Is that true

I also noticed same thing.
Poslano sa mog SM-G920F koristeći Tapatalk

I noticed it too. I stopped uaing fast charging.
You get more sot if u normal charge

Gonna try it out asap

How much difference? Like between SoT on Fast and Normal charge?
Just wanted to know, in order to decide whether it's work giving up Fast Charge

I have noticed 15 to 20% increase in sot or standby in stock rom.

Okay. Any example? Screenshots? Figures of SoT? Like say an improvement from 4 hours SoT to 4 hours 40 minutes?

Interesting, I will try out too

Same here. Draining my battery to try out normal charge.

Any updates?

Another thing.... Will Wireless charging/Normal charging give same battery life , vs Fast Charging?
---------- Post added at 02:36 PM ---------- Previous post was at 02:22 PM ----------
No difference for me

Same test here. Using normal charge, sot seems bigger than Quick charge...

brand new s8, questionable battery life

guys i played with my new snapdragon s8 last night for like 2-3 hours and set everything up and i love it!
the only worry is so far the battery drain is a little more than i would like compared to my exynose S7 Edge. I have all the same apps and accounts setup now on my s8, and just in the few hours i played with it last night the battery drain was more than the s7e was in the past with that same medium/high brightness and watching a lot of videos and installing apps.
then last night, my new s8 on AIRPLANE mode overnight lost about 10-11% battery life which seems too much on airplane mode, my s7e exynos would loose only a few % overnight on airplane mode.
maybe the phone battery needs to calibrate for a few days? maybe the OS needs to optimize itself more? idk. but right now its morning here and im going to charge it too 100% and see how it fares throughout my work day

When you first get a phone, it'll use a lot more battery until it is fully set up and settled in. I give my new phones at least a week to properly settle before I make any judgement on the battery life.
Remember, you've downloaded, lots of apps, synced accounts and various bits. Give it a few days before you worry about it

Turn off Samsung backup.

cool ill figure out how to do that and try it

Give it a couple days and update us again - you can also use AccuBattery for a more detailed statistic.
~10% overnight with airplane mode is truly a lot. You should be getting about 1% overnight drain after the phone settles.

I get about 3 hours of SOT if i'm lucky on mine. I play a lot of BT Spotify in my truck as i'm in and out of my vehicle all day long. I was hoping for better, I even followed the guide to disable a bunch of the packages etc thinking i'd get more and didnt raise it any.

Samsung Backup only starts when your phone is charged.

set your phone according to the debloat recommendations here https://www.xda-developers.com/the-...r-community-radically-improved-my-experience/ and you'll be over 5 hours SoT, my battery life was poor to but this link really helped.

Sorry to hear that! Not sure what else to try.

Do you have Greenify installed? It caused issues for me in terms of impacting negatively on battery life, i uninstalled it and saw big improvement.
