Oh sorry my apologies :), I see where I was wrong. I totally agree with you

That's a good write up because one thing that's coming out clearly is your usage patterns are different compared to others which is fine. You actually make a very valid point this time in the part where you say

I say so because in all my solutions right from the s4, when I compare your efforts to what I have had to do to come to a solution I realize, I have also been forced to explore system apps (that's out of layman's territory as you say) which I never thought I'd have to do when buying the phone. By very far it's not a weak argument, you have made your point my friend, I hear you and I appreciate that. So I guess it depends on how much it bugs you that you are going above and beyond layman's territory, not that I enjoy it either. I didn't mean it to come out the way it did, it's just that very many make claims they are unable to support but yours doesn't fall under those now. Let me just say where am coming from, I just like getting to the bottom of things without rushing into conclusions. I appreciate your post and no I don't work for Samsung.
[Galaxy Note 4 General] Batfink33:
Android seems to be becoming (or Lollipop anyway) a device you really have to delve into to get good battery life by disabling apps and services . It's most certainly not an IOS device in that it's plug and play. I regularly now get 5-6 hours SOT but I've really had to research, root and monitor apps and services that are running, only this week I started having crazy drain, looked at the CPU cycles and noticed something called "secure system ui" sucking up the CPU, after disabling it, it's back to normal again. I don't think it's a Note 4 specific thing as reports are that the G4 gets around 3-4 SOT and the S6 around 3. For the average user this is not good as it requires knowledge and rooting and most people will think "this is a device with poor battery life" without finding out what is going on. Google really have to get a grip on this.

here is my n910f 6th gear kk, custom kernel, rooted, amplify+greenify'ed, with velis auto brightness. I really don't miss ? crap, where it was hard to settle 4h of SoT. now the night break eats only 4-5%.

My 910U on 5.0.1 after waking up this morning, charged to 100% then unplugged just before I went to sleep (yes I have a terrible sleep cycle but that's what you get working in restaurants)
[Galaxy Note 4 General] Kernel ranger:
This is now becoming a disturbing trend and unfortunately this is what we have to put up with. Have you managed to find out what triggered the "secure system ui" to go ballistic?

I have just come from confirming that majority of the very poor performing Note 4s for no apparent reason have everything to do with the mobile network signal being weak costing you upto 4hrs of SOT. So inhabitants in various regions will receive mixed performance by the same carrier depending on the signal strength but due diligence must be done first before concluding that the mobile signal is too weak.
[Galaxy Note 4 General] Batfink33:
No, I dont know what caused it. Interestingly I've been out of my own country (UK) visiting the US for the past two weeks travelling so perhaps the mobile signal was causing the high drain and it triggered something in the secure UI.

I also found when I was travelling because I had my mobile data off and wasn't connected to wifi, my contacts were trying to sync but couldn't reach the Google servers and this was causing wakelocks and high drain, a crazy situation and one which is probably quite easily rectified by Google. Now I'm home and disabled the Secure UI and have a stable data connection, I'm back to 5-6hrs SOT V 2-3hrs last week.
[Galaxy Note 4 General] Kernel ranger:
Very interesting, the more I hang around here, the more I anticipate my next move should I ran into any of these behaviors. Keep us posted. I guess too many things in v5.0.1 are too automated in a bruteforce manner without a second thought about impact on battery life. I can conclude one thing right away just from that. It was so assumed that all signal reception (Mobile network signal, WiFi signal and various network accessibility... etc) will be ideal hence real world situations were never explored before the release of v5.0.1 causing alot of mixed reactions from people. The unfortunate bit about this is the layman will not understand that it's a teething problem that an update will satisfactorily rectify. This is further worsened by delayed updates to consumers. The hardware is never the problem, the software is usually the culprit, no wonder custom roms are an option, all too irresistibly attractive to the extreme performance enthusiasts.
[Galaxy Note 4 General] Batfink33:
I think the hardware in the Note 4 is actually good and as battery friendly as you can get on a QHD device. The AMOLED display is very efficient and the S805 gives as good a performance as the S800 running a 1080 display with little or no thermal throttling. All the battery problems are no doubt coming from the software. I notice on the G4 forums, they're getting an average of 3-4 hours SOT so it looks like it has bloat and Lollipop problems also. I noticed also that in the Google IO presentation for M that they have fixed 1000+ bugs from LP and that battery life has increase quite a bit (although we've heard that before) so it may take an update to M for all Android phones to get good battery life. Unfortunately until then I'll have to keep using TREPN, Servicely and BBS to kill any rogue apps and services.
[Galaxy Note 4 General] Chad_Petree:
U think most of the bugs will be squashed with 5.1 it made a big difference on my Nexus 6, I'm kinda of afraid Samsung will skip the 5.1.1 update and go straight to Android M and that will leave us months with this laggy and battery hogging version of lollipop :/
[Galaxy Note 4 General] zkyevolved:
This is my battery life today... Very little usage, and look at that battery usage! Arg... It must be a 5.0 bug.

[Galaxy Note 4 General] Batfink33:
What's interesting is the G4 ships with 5.1 and they're also getting 3-4 SOT average according to their battery threads. Might be a bloatware issue as I'd imagine the G4 hardware is fairly power efficient on the hardware side. I was reading comments by Francisco Franco and he was looking at the new M kernel and how it is employing various new power suspending techniques,they made some impressive battery claims at the IO.

If you're not rooted, run TREPN profiler and see if there's any rogue apps or services using CPU cycles. Problem is, if you're not rooted, even if there is apps or services using your CPU, there's nothing you can do about it. Its difficult to tell from those screenshots but if you get 3-4 SOT then that's pretty normal, from the small flat lines that look like sleep, it does look like your phone is deep sleeping.
[Galaxy Note 4 General] zkyevolved:
Awesome. Thanks for the recommendation... I am surprised that swiftkey is taking CPU, especially since it isn't my primary keyboard.

View attachment 3341180

What could the settings be? Hmm.
[Galaxy Note 4 General] Chad_Petree:
I think the LG G4 does nor have stellar battery due to the snapdragon 808 not being really power efficient, Qualcomm kinda dropped the ball this year with their processors, I'm hoping that the 820 will not disappoint
[Galaxy Note 4 General] Batfink33:
Settings runs high on mine also, not sure why. It's when media server or some other strange app or service starts going crazy that's when I get problems.

Round 2 shows log agent. I imagine that it's the app itself logging? Does that sound about right? Thanks [emoji1]
[Galaxy Note 4 General] Batfink33:
Security Log Agent is high,it's not the app itself, it's some sort of Samsung bloat that will be draining heavily, something needs frozen or disabled there. I've disabled and frozen Health as I never use it and will be counting steps etc and using CPU in the background.

[Galaxy Note 4 General] cricketgirl90:
My phones standby time increased considerably by just changing the network from gsm/wcdma to wcdma only. I guess I will get dropped signals here and there but I get 3G and home and work.. so shudnt be a problem.
[Galaxy Note 4 General] Kernel ranger:
[MENTION=566169]both[/MENTION] of you: Just when I thought there was light at the end of the tunnel, turns out it was an approaching train... Noooo! Just what is wrong with these guys?? Why Lollipop then in the first place if Android M is going to fix its issues

What!!!!! Man I thought you were rooted all this time! Now while you are at the recommendation of TREPN profiler, if you arent afraid of neutering or down sizing your OS like me, you can use Root App Deleter to completely uproot ANYTHING permanently from the OS.
[Galaxy Note 4 General] Batfink33:
Lollipop seems to have been a big jump from KK. It was perhaps a step too far and more time was needed to properly refine the OS. M looks like much more of an evolution and refinement of LP. With LP and Samsung though, there's all sorts of Samsung bloat kicking off so it's not all LPs fault.
[Galaxy Note 4 General] Kernel ranger:
The worst thing about it is it's true, I wish you never knew what you were saying, it sounds sooo bad.
[Galaxy Note 4 General] zkyevolved:
Lol. I've never rooted a device. I don't think I should have to. As you can see from my signature, I change devices quite often. I think a flagship phone should be that, a flagship phone. It should work well right off the bat. If it doesn't, it's going back. I'm debating returning my Note 4 for a Nexus 6... I know, buck for buck, the Note 4 is a lot better of a device (features and hardware). But these little bugs ruin the experience for me. This thread is about battery life - so I'll only mention, once again, the lag on such a top tier phone. Shame on Samsung for Lag and battery life problems! My partner has a Z Ultra, a 2013 device, and it often pulls up multitasking screen faster than me. And reviewing images? I won't even dignify that...

If I do change, I'd miss the camera. That's it... :(
[Galaxy Note 4 General] zkyevolved:
I want to thank you guys. My battery this morning is going strong like a champ. I took it off the charger at 100% at 7.30 am this morning. Now it's 11.15 and I'm at 88%. I went for a run and used endomondo and took a couple of phone calls. So far. So good. I guess s health was a nightmare...
[Galaxy Note 4 General] Kernel ranger:
Finally! Just what I wanted to here, that you have gotten to the bottom of your problem, I knew it had to be some software issue, am even surprised that it performed that way unrooted.... I just didn't see how such a device can just let you down like that considering the hardware that's running it. Mine I haven't really put it on the "grid" yet, am studying what it's like to have a 100% ideal situation, then have it join the system later so it's results aren't like any phone here so far. It's now down to 65% after 2days 15hrs 45min, pow saving modes off, WiFi ran for 1day 1hr 3min but is now disabled, removed animations via developer menu, all bloatware apps are uninstalled/disabled, unrooted yet, SOT - 3hrs and counting.
[Galaxy Note 4 General] zkyevolved:
Wow. Then mine is still terrible. Haha. Check these out! And I was happy with these because there's an improvement.

View attachment 3342845View attachment 3342846
[Galaxy Note 4 General] Kernel ranger:
Mine is in an ideal test situation (dream world of phones), not really real world as such because it is doing so off the grid (out of network=no mobile network provider). At the end of the test I'll post the screenies here because should I do now, the battery will get charged and I don't want it charged until this test is over. I'll be using this to monitor various changes occurring in it and how it gets affected to very easily track what's going on in it. This test will tell me how my signal coverage affects my battery life since that's the primary lead factor in Note 4 battery drain issue.

About yours, I still feel there's alot more that can be done to better it if you are willing to explore other alternatives like you did with S health for endomondo. It looks like there's a system app really working your battery, it might mean you make do with less integrated or featured apps for better battery life.
[Galaxy Note 4 General] zkyevolved:
I can't really afford to root. If I ever get a defective unit or something goes wrong, they generally return all my money. But if I tamper with it, I get nothing. So for me it's worth it to not root my devices because of that. [emoji1] plus, in all honesty, I don't think I should have to do that to get decent battery life.
[Galaxy Note 4 General] zkyevolved:
Any idea how to identify what is being used? I always get settings as the CPU killer here. View attachment 3344178

It's always the #1 thing that is using my CPU. [emoji35] maybe a debugging solution and plug it into the PC to monitor? I'd like to see what process is using 10% of my CPU 24/7!
[Galaxy Note 4 General] Batfink33:
I've pretty much frozen, and disabled everything possible and still get the settings running at 7-10%. With that I get 5.30-6hrs SOT. It may just be important system apps but I haven't found a cause. If you take a look at "settings" in the application section, it gives you all the apps that run under that heading.
[Galaxy Note 4 General] zkyevolved:
Yeah, but that list is infinite xD haha. OK, good to know that this is normal. Thanks :)
[Galaxy Note 4 General] Batfink33:
It would take going through that list one by one and freezing the apps until the CPU cycles went down, but then you'd have to make sure you weren't getting any FCs. Can't really be bothered doing all that! Lol.

You mean this very short list? Haha ? aandeven then, Android system is still included. So... Yeah... Lol. View attachment 3344375

[Galaxy Note 4 General] Kernel ranger:
Some app is really working your battery, install TREPN profiler and get the culprit and lock it down.
[Galaxy Note 4 General] zkyevolved:
Your device is completely fine. Your device is hardly ever awake when the screen isn't on. So... You're good. 4 hours of SoT is good :P I never get 4 hours of SoT xD.
[Galaxy Note 4 General] Kernel ranger:
Like I said I would post my results at the end of the test here and here's what I got. It does prove that the Note 4 is a very capable phone performance-wise, it's just overloaded with bloatware and unfortunately you may be in an area prone to poor network signal. I did realize that my phone's hotword worked only a few hrs the first time I tried it but later on the microphone became outlined and no longer responds. When it was working, the microphone was all black. Trying to access the hotword settings just shows it greyed out and it states that it is searching for settings (has been doing so for the last 4 days during the test). WiFi was just on for the first day only, turned it off there after.

The device is unrooted
[Galaxy Note 4 General] dzebrys:
your WiFi is always on even the screen is off. I suggest to go to wifi settings, advanced menu and forbid to always scan wifi networks (or sth alike). 2nd, same menu, select keep wifi on during sleep only when plugged in. also common pitfal of fresh device is localization set to high accuracy, change it to power saving mode. my current battery time is 1d4h, 10% remaining, 6h42m SOT, seems there is a long road ahead you.

I also remember uninstalling Telekom.de app, Amazon and Hang out (these ones come out permanently without any rooting or hassle). I own this phone it's not leased and it's factory unlocked.

The main biggest problem is the bloatware that comes with it, other far better alternatives can replace all the above with remarkable battery life, I never ever expect this from it, am also equally surprised because my exynos s4 couldn't do this no matter how hard I tried. What I don't understand at all is how it is able to track my mobile operator signal after removing the simcard that actually helps it connect. It even states the signal strength changing at different locations as I move around with it same way it would if the simcard was in it.

I just knew it! Your welcome :good:

Update on battery findings - Samsung TW ROMs much better than CM/AOSP on Note 4!

Hey guys, another update on my findings on my pursuit to great battery life. Basically, use Samsung TW ROMS!

I recently discovered that xposed can be used on Sammy TW ROMs so I decided to try it out and 8 hours in it's already blown any CM/AOSP experience out of the water. Using THIS GUIDE I have already (on first discharge) achieved 1hr 20mins SOT over 8 hours off the charger and sitting at 84% remaining. Whilst the screen off discharge and wakelocks/alarms as the same as on CM/AOSP, the discharge during general use is far better and is where I'm seeing the improvement I think. Sammy TW ROMs seem to handle processes and resources better or something and give better discharge.

This was on SimplLite 3.2F BOE2. I am now gonna flash the new Nameless ROM which apparently has more battery tweaks and is a little faster and see if that is any better.

TL;DR If you want good battery life, flash BOE2 bootloader, modem and ROM (such as SimplLite or Nameless ROM BOE2) and use THIS GUIDE. It's that ezpz!

If Batfink33's recommendation hasn't worked you could use Disable service (needs root). The app is so powerful it could soft brick your phone if you disable the wrong service. Your case is clear, a service is misusing its assigned privileges to wake your phone up indefinitely. Good thing with disabling services is the app can stay and will only wake when you need it but some apps need the service running or they will be broken. So it's a tricky affair but completely do-able.

That's an app overworking your battery (TREPN profiler should point you in the right direction)
[Galaxy Note 4 General] M7md3li:
Disabled anything or just out of the box ?
[Galaxy Note 4 General] Batfink33:
Another good app I've found is Rom Toolbox (think it needs root). If you go to the "apps" section in it, it shows you all the system and downloaded apps. The apps that are running and using your CPU have a small "electric" type of symbol beside them. You can usually figure out what shouldn't be running and then long press on the app and freeze it. I use a mixture of Servicely, Rom Toolbox and Trepn to track down, disable and hibernate the offending apps and services.
[Galaxy Note 4 General] M7md3li:
Is using 3rd party keywords improve battery life? Because Samsung keyword is on top of my trepn profile of cpu load
[Galaxy Note 4 General] Batfink33:
Try SwiftKey. Better than Samsungs own keyboard and uses low amounts of CPU. Once you've got it installed, if freeze Samsungs keyboard to make sure it doesn't suck up anymore CPU cycles.
