Premise:
idle battery drain in LP is much worse than in KK (1% per 1 hour vs. 3 hours.)
Personal experience : after disabling most of background apps in both OS's, the battery drain in LP is about 1% per hour, while it was 1% per 3 hours in KK.
New information:
I did a new test. I restarted the phone and charged it full. I then left it idle for about 6 hours.
Here are the results after 6 hours of a charged idle phone.

Conclusions:
1) The constant wakelocks in idle state are due to S-Health app. They are not responsible for the battery drain.
2) Cleanly after restart, the phone drains the battery in idle mode at a rate of 1% per 3 hours, even in LP.
3) Something else is responsible for draining the battery at 3x the rate (of 1% per 1 hour.) This new culprit is only introduced on using the phone for a while.
I will continue testing this.
Any new ideas are appreciated.
The single biggest reason that I miss root is to figure out wakelocks on these things.

Someone posted a way to get Wakelock Detector working w/o root:
1) Connect phone to usb.
2) Do "adb devices" then do "adb tcpip 5555"
3) Open Terminal Emulator and do "adb kill-server" and "adb devices"
4) At this point, Wakelock Detector works.
Thanks for that info. I'll have to give that a try.

You can use wakelock detector without root, over usb adb

I have been seeing the same awake vs screen on behaviour, my fiance isn't seeing that trend as much and her battery life is better. I'm not complaining much about mine, but it could be better. I've tried clearing cache, battery pull, uninstalling apps, and changing sync settings.
Android Central published an article about the bad battery life on the S6. Samsung just updated the push service that affects the S6, S5 and Note series. Might be worth looking into.

I got wakelock detector set up with the instructions in this thread. It sort of works. It shows no Kernel wakelocks, and I think that it's very unlikely that my phone has had no Kernel wakelocks in the last 18 hours.
Yes I have been tracking this Note 4 with WLD for a couple months now and I haven't been able to pinpoit the issue of battery/wakelocks. It seems to be something very fundamental inside android itself. My wife's Note 3 absolutely does not have these problems. She can get 8 hours of screen time in a day. I am lucky to hit 4

Take a look I am running SC 2.4 and I had my data on and I went to 79 percent battery in a little over an hour mostly on standby just now I charged my phone to 100 percent and its at 90 while leaving wifi on and a phone call

EB01 has a bug in its sensor code, so turning off AutoRotate will help. It's still not a WHOLE lot better, but it's at least serviceable that way.
Hopefully, the rumors about the update/OTA were true, and we'll see an updated build (EB09 is sticking in my brain for some weird reason, but don't take that as anything real) that fixes the sensor code and anything else that's eating up battery.
Did you do all the flashing when at 100% battery? It's possibly your battery stats are just inaccurate.
Let the phone charge to 100%, then with the phone still plugged in, shut it down so you get JUST the charging screen, and let that go to 100%. Then, boot into CWM and delete battery stats, and then go back to the powered-off-charging-screen and let it go back to 100%, then boot back into your OS. Some people recommend draining the battery most all the way, then charging it back up, but I'm not sure if that's really necessary.
Also, apparently there's a GPS bug in EB01 which causes it not to sleep, which'll drain your battery fast as well (though I don't see the GPS icon on your screen). You might also have some battery hog in the background slaughtereing battey life (the battery use screen might be able to lend some help for that).
Try using an app called juice defender, I found it to help my battery a lot.
SC 2.4 hides the icon.
I was getting a wakelock from Android System earlier today, but that has finally resolved itself and my phone is sleeping now.
I am not a noon so I know about wiping batt stats and did that I have used juice defender before but I just don't see a whole reason that it should drain that quick

No issues with battery life AT ALL with EB01. In fact, the BEST battery life I've EVER gotten, even better than Adrynalyne's UV kernels (no offense bud)
Yesterday, I unplugged around 10, got off work work at 830, was home by about 930, and STILL had some 34% left, 11 hours later. I'VE NEVER been able to go that long on a single charge. And I leave auto-rotate on.
What REALLY helped me, was turning off the GPS when not in use. MAN....what a difference !!!!
Hello folks,
I've had the Rogers Galaxy S 5 for about a week now, and since day 1 I have noticed excessive battery drain by "Android System". This source of drainage occurs especially during idle periods of time causing me to experience rather poor battery performance.
This here is a sample of what my battery stats look like at any given time, notice "Android System" is virtually always the number 1 source of battery consumption.

I executed a factory reset on the second day of ownership to examine whether this drain would be solved. It wasn't.
I went to bed, and woke up in the morning to check Gsam Battery monitor which gave me this chart:
Notice the part I highlighted in red which demonstrates the overnight battery usage!
Also, GSAM battery monitor still displays "Android System" as the source of the drain.
Among my colleagues I am the only one experiencing this phenomenon, and I am going to factory reset for the third time right now.
Going to run the stock firmware to see whether I am still experiencing this.
I will report back with any new findings soon, hold on tight to your seats!

I suggest you do the following,
-Disable Location in the notification drop down
-Turn off Hot Word detection for Google Voice Commands.
-Disable bloatware
-Turn off always active WiFi in advanced WiFi settings.

AND,
Try giving it a week to 'settle' without resetting it...
It needs to figure itself out...
All my family member noticed significantly better battery AFTER 1st week.

Certainly performed all of the above right after factory reset! Battery still dropped over 10% overnight on standby.

Makes sense, I will run a few charge cycles!
This has happened multiple times on my Galaxy s4. Today was the worst however. My phone was on 51% battery (supposedly) and then, the phone just turns off while I was in an app, without any kind of low battery warning, it was running as normal before this happened, I start the phone up again and bam, 1% battery remaining. Here it is on the battery screen:

My battery was dead by 2pm in the day which is also significantly worse than normal. This is with just 45 minutes screen on time:
and just 7 hours on battery:
And with no apps sucking up battery life.
Has anyone had this issue before and is there any possible way to fix this?
Charge to 100%. Pull battery. Put it back in and charge it again while off to 100%. If that doesnt fix it then get a new battery.

Hi ,
It could be lots of things...battery , phone not going in deep sleep , settings
First thing I would do is use an app like Better Battery Stats and really see what is going on ( kernel wakelocks) , who is keeping the phone up all the time , then i would review all my settings like FB , mail , location ...any syncing related app that may be going crazy and of course battery may be going bad
Look like a bad/faulty battery for me.

Keep in mind that battery percentage is never 100% accurate. All devices with batteries (with a percentage meter) has this.
But yeah, use better battery stats to check wakelocks.
Also a trick to calibrate the fuel gauche chip is to take out the battery for 3-5 minutes. It will be more calibrated than before.
Battery would fall 2% on the screen, it shows in battery reporting you can see the line drops steeply within 1 minute then stays stable (ignore the part where my device was asleep).
been very inaccurate with reporting % it randomly died at 12% (lowest its been since i got it 3 weeks ago) and when i power back on its at 2%. i charged back up to 40% and let it drop to 12% and the same happened.
i could live with the 3hr SOT if i got a good report of how much % was left so i can conserve usage if need be.
Running stock oxygen 2.1.1
then rooted and installed AK kernel (SOT is a little better) but still % dropping. i even super underclocked and saw the same effect
sent a ticket to OP - hoping its a defect and they can replace it

By what I read, it's a normal behavior when device wakes up from sleep.
It seems that, when device is asleep, even battery stats aren't updated, to avoid unnecessary drain. So, once it wakes up and you use it for couple minutes, android get a chance to record stats and update actual battery percentage.
Again, this is the explanation I read on such a question, and it does makes sense.

i managed to underclock enough to make the other percentages to show up - so it is working just i guess polling is slow.
the 12% dead battery isnt normal though. havnt had it since then but if reset a few times. now switched to a custom rom (keep loosing LTE) but ill figure it out, thanks!
I recently bought the lg g6 h870 for europe and i saw that phone idle is eating like 46-50% and android os is eating like 22-25%.This morning i saw that phone idle ate like 75%.Is that even normal.I have to mention that i am on july security patch due to the lack of updates for europe.Anybody knows how to stop phone idle using that much,or i have to wait untill oreo?

We have to wait. This is most likely because of Android 7.0 idle battery drain bug which causes "Phone idle" to be very high and battery-hungry.
I have tried greenify and i have location turned off wifi off bluetooth nfc all are off and i am still getting like 77% phone idle and 22 percent android os while screen is eating only 20% and other apps 2-7%.I am really getting desperate.

Yes, as I mentioned, 7.0 is bugged and there are loads of similar topics not only here, on G6 forum, but also on Nexus, Samsung, Sony forums.
Most of them are connected with "Phone idle" issue.

That's nice mine consumes over 2000Mah over the same amount of time.
Hi all, got H870DS model a week ago and on the first run used LG Mobile Switch as suggested by the device. Transferred all data and settings from G4, all good, didn't take very long. The first 48 hours were quite bad: 2-3% of battery every hour when idling.
Tried Greenefy, all those things, but with no root - poinless. Tried phone hidden menu as well.
Then I downloaded and applied one of the latest HK firmware - still the same.
Note that all this time the phone had no SIM, but was connected to WiFi with all social apps running on background.
Then I decided to go long way: back to factory settings and update the phone in portions. Log in Google account, basic apps - and leave the phone for 2-3 hours. Another 2-3 apps and wait again.
Last ones - social and messengers: one by one, like on the minefield. Folio used instead of FB.
Result: 0% drain overnight. 1% used in the last 14 hours.
Happy with that.
Not sure what kind of settings were transferred from G4 to G6, but that obviously was the reason (in my case) for the drain.
