The wifi example was not meant as a real life example, just to show you that no matter how you optimize a device, hardware power is the same among them, just no way getting around it

Real life usage web browsing, gaming, video-ing etc will yield 4-6 hours SoT depending on tons of factors like cpu usage, wifi usage, screen brightness, screen whiteness, hardware components enabled etc. Sure you can get easily past that if you limit your CPU frequencies for example or run some specific apps that dont consume much CPU. And your screen brightness should be low and always remember that the colour of your screen is a huge factor too. White = battery killing.
[Galaxy Note 4 General] bronx:
Then apps I'm using must be doing some weird stuff to my phone, as most of them are using white as a background (I'm not a 'night mode' type of person).

The log and screenshots I've provided were produced after three hours of me sitting with my phone in my hand, reading news, articles, watching funny cat videos - you name it. The phone wasn't just laying with screen turned on, it was used normally. In the meantime I was also using WhatsApp and did some other stuff. My brightness settings are attached in screenshot.

Now, I don't really care if you participated in creation or just tweaking/porting of cm (or it's parts), but that doesn't allow you to be rude to other users and suggest that they are lying.

Shame on you, as you just do not know how to converse in polite and civilised manner, while people like you should shine above the rest.
[Galaxy Note 4 General] gekkehenkie11:
LOL remember that in your very first post, where you reacted to me (not the other way around !) you accused me of not being able to do math. So what kind of response do you assume if you start attacking people like that ? You expect a lot of love ?
[Galaxy Note 4 General] bronx:
I was just joking, hence the ;) wink wink, but whatever... As I said before, you know better lol. ;)

This guys whit 8/10/15 SoT need report to samsung that...And samsung wil be fix that bug in new update 5.1.1 :P :D
[Galaxy Note 4 General] SnoopBok:
Need help!

I am facing huge battery drains in standby. I'm currently using CM12.1 official. I tried a lot to figure out what's causing the drain and I tried a lot to temper it. What I did so far: tried Xposed with Amplify and Greenify, tried to block Google services, did some clean installs, tried different modems and bootloaders, etc. Note that when I was using TW my battery was using about 0,6%/h in standby.

Some nights ago my phone lost 24% in 8 hours standby time. The device was kept awake for approximately half the time, almost 4 hours . I tried to figure out what's causing it, in my opinion there's nothing ordinary (like a lot of wakelocks/alarms) that could be the cause of the problem. A couple of days ago I noticed the kernel wakelocks where high, so I tried the Vision kernel, and the drain tempered to about 1,5%/h. Unfortunately that's still a high number, and unfortunately the kernel development has stopped and I prefer to use the stock kernel. I really like this ROM, I prefer it over all other ROMS.

I attached a log of BBS stats, can somebody take a look at it and help me? The stats where gathered after a clean install, and no usage of Xposed, Greenify etc. I'm in an area with good wifi and cell reception, so these can't be the cause. The 'standard' android battery usage point out 'Android system' and 'Android OS' as the cause of the drain.

I did post it in the ROM's thread but no reaction so far, it's really driving me crazy. I would be very happy if someone can help me :o (last hour in standby my phone lost 6% :()

[Galaxy Note 4 General] POLO_i780:
No CPU Power Saving, and I am on 31% with 5hours SOT, seems like my Note 4 will cross 6hours SOT despite no CPU slowing down and so on. I will post my results when I cross 6hours. If my laptop continues to not find my Note 4 with Dumpsys, then I'll just post CPU-Z Screenshot to show that I have a stock battery, as some naysayers in the 5.1.1 thread claimed I had a larger battery, LMFAO!
[Galaxy Note 4 General] SnoopBok:
Thanks [MENTION=4884466]Jovan1997[/MENTION]. It's very strange, because i'm using wifi and 4G without any problems :confused:

Could it be related to this post: http://xdaforums.com/showpost.php?p=61989573&postcount=338

Any suggestions to fix it? Because I tried a lot of things to fix it: flash to stock LL, stock KK, different modems, different ROMS, different bootloaders, Xposed, etc.
[Galaxy Note 4 General] cornelito:
Bronx, seriously you're pathetic.
[Galaxy Note 4 General] Jovan1997:
I dont list this logs but will be see again..Try to install custom kernel and stock ROM..than disable apps if u dont use,like whatapps,turn off sync...etc

And better to create logs whit adb(u have instruction 2/3page up)..

No or Unknown Signal (): 8 h 7 m 53 s 100,0%

and something keep awake ur phone

Deep Sleep (): 4 h 23 m 31 s 54,0%
Awake (): 3 h 44 m 21 s 46,0%
Screen On (): 25 s 0,1%

***you can try to put phone into SafeMode and see..Maybe some of custom apps keep awake phone(screen,cpu whatevet)

or do a test(this one from Saphhire):Make your battery before going to sleep about 20% and turn it off. Go sleeping. After 8-10 hrs try to switch it on again. If it doesnt switch on, then you have defective mainboard.
[Galaxy Note 4 General] gekkehenkie11:
Just make an adb dumpsys batterystats like explained a few pages back, look at the wakelock section in it (it shows more/better info than all those apps out there) and that will show you which app keeps your phone awake. Because, as explained in the post above this one, that's your problem. Your phone doesnt go to sleep so a wakelock is keeping it awake.

[Galaxy Note 4 General] gekkehenkie11:
Post full dumpsys log please, with all info. Also a screenshot of betterbatterystats/Cpu states screen would be useful.

BTW I'm not saying you can't get past 6 hours. You easily can get up to 12 SoT hours, probably even much more, just dont touch the screen and just stare at it and you will have the best SoT ever ;)

I said you can't get it with normal web browsing/gaming/video usage, without limiting the CPU.
[Galaxy Note 4 General] POLO_i780:
I posted EVERYTHING you wanted before in the previous page including the dumpsys log, I was so tired I didn't even bother removing my email addresses. So I am done. You never asked for betterbatterystats/cpu states screen last time, thats your fault.

Work with what I gave you, which is what you wanted last time. :)

You said I couldn't past 6hours SOT with usage and no CPU Power Saving, which I proved I can in the previous page, yet you still go on about not touching the screen, LMAO, you really can't accept it when someone proves you wrong, shame :D
[Galaxy Note 4 General] kuladiamond:
What's the common battery life on stock unrooted in terms of usual SOT?
[Galaxy Note 4 General] POLO_i780:
I'm on Stock Unrooted and I get well above 6hours SOT. From my run yesterday I get around 7hours SOT with No Power Saving and around 8hours SOT with CPU Power Saving.

Others get around the same as me, while others report 4-6hours, it is all down to a variety of factors e.g. apps you use, network quality, WiFi usage, 3G and/or 4G usage, screen brightness and so on.
[Galaxy Note 4 General] kuladiamond:
And this is on Lollipop? Cause I heard that people have been having a decrease in battery life when on Lollipop. I'm currently considering purchasing a note 4 since I'm thinking about replacing both my aging nexus 4 and nexus 7 with a phablet. I mostly browse the web and watch YouTube videos.
[Galaxy Note 4 General] POLO_i780:
Yep, I'm on 5.0.1 Lollipop, using Samsungs Nordic (NEE) POF2 ROM.

The Note 4 will replace your Nexus 4 and give you far more battery and features than you know what to do with, BUT I'd keep the Nexus 7 around, for the days when a smaller screen is not enough, thats why I have kept my iPad 4 and will probably get either iPad Air 3, Galaxy Note 12.2 or an iPad Pro, as there are times when even the large 5.7incher of the Note 4 just isn't enough.
[Galaxy Note 4 General] kuladiamond:
The nexus 7 is the 2012 version, and the battery life seems to last only thru the day when it used to last 2 days. That's why I'm thinking of replacing both for 1 device. Would the note 4 handle 5-6 hrs of mix browsing and YouTube vids?
[Galaxy Note 4 General] POLO_i780:
Web browsing, yes, I am not sure about YouTube, I watch max 2-3 vids in a week on my phone, I would assume YouTube will be quite taxing due to high data usage, but it will out last your Nexus 4 without a doubt.

The 5.1.1 update for Tmobile and Sprint apparently brings even better battery life to the Note 4, so expect a nice jump from your Nexus 4, I am reluctant to compare to a tablet though, I use my iPad now and then so battery lasts like a week due to little usage.
[Galaxy Note 4 General] kuladiamond:
For me, it's gonna be the international version. Plus, I mostly use WiFi at home for the YouTube streaming. And yeah, I understand that without trying it in real life as far as my usage goes, I won't know if the device is gonna suit my needs. Thanks though for your suggestions :)
[Galaxy Note 4 General] SnoopBok:
Thanks guys for the help. I made a dump with adb after a long night (drain was not as high as before, but still too high :confused:), I attached it to this post. I really do not know what's keeping the device awake, I noticed this:

All wakeup reasons:
Wakeup reason unknown: 1h 33m 53s 774ms (3748 times) realtime

What's keeping the device awake? I thought it could be EFS related (after searching on XDA) but I still can recover the IMEI (*#06#). So that can't be the problem, right?

[Galaxy Note 4 General] gekkehenkie11:
No you did not, you posted only like 33% of the whole file, all the important info is missing, what info can we get from this log ? Nothing at all !

Sure, no problem. But then just dont post nothing at all next time if you dont care about posting proof.

I wanted the dumpsys file, you post 1/3th of it that has no interesting info at all. Just look at Snoopbok's post. THAT's what I want. He understands it, why dont you ?

LOL. I can post a 12 hours SoT screenshot. So what ?

---------- Post added at 02:17 PM ---------- Previous post was at 02:11 PM ----------

At least you DO understand how to make a dumpsys file :) But there's something very very weird with it. There are some wakelocks but nothing that's out of the ordinary or that could cause your problems .But this is the weird thing, I have never seen this before, your whole first part of the log is just FILLED with this line:

+9h03m09s478ms (2) 089 +running wake_reason=0:"unknown"

Wake reason unknown ??? I've never seen this before. What I suggest is to to just wipe everything, flash BOB4 modem and bootloader (if you're on 910F) and then install CM again.

*EDIT a few others you can find via google having the same problem: http://xdaforums.com/showpost.php?p=59161985&postcount=48 he seems to be on stock. I'm starting to think this might be a hardware problem though ... But again, try first wiping everything and reinstall modem/bootloader etc. Or maybe easier and better, just flash a whole stock TW Odin image and see how that works. And contact this guy, ask him if he found a solution
[Galaxy Note 4 General] Wolf1203:
sigh… I spent the last hour reading the last 20 pages of this discussion, all I can say this that gekkehenkie11 u totally deserved it… why do u even bother trying to analyze the battery states of those idiots who are just showing off their extreme cases while they are not willing to provide an useful data and/or not able to backup their claim with their data?

This thread should be meant to help other people identifying and solving their battery issues, just ignore those idiots please.
[Galaxy Note 4 General] gekkehenkie11:
Because you will always see some newbies then, who dont understand that anything beyond 6 SoT is simply impossible with normal usage and CPU governance, believe what these guys post and then think there's something wrong with their system if they can't get past 6 hour SoT. Or that they simply are missing some 'secret option' that will get them past 6 hours :) But yeah, if they dont even want to post a log, then best to just ignore them, totally agreed there.
[Galaxy Note 4 General] tmac31:
Just browse using wifi and watch videos dont even call some1 you can easyly get over 6 hours thats what they do. There will be always some1 who claims he gets insane sot. For example i get only 3.5 hours sot on s6 edge but people are posting 6-7 hours sot. Its possible they dont need to provide any logs you should not even bother with them and waste your time. Comparing sot is bull**** unless you are the user of the both phones.

Like me almost same usage on the phones on my signature. S6 edge 3.5 hours note 4 exynos 6 hours 6 plus 6 hours and note edge 5 hours. Eventhough i use them almost in same scenarios comparing sot still is not the best way.
[Galaxy Note 4 General] gekkehenkie11:
Web browsing is highly CPU intensive, so that's exactly what they do NOT do. Other than that I agree to what you said, comparing SoT is pretty useless in itself. All that matters is: what do you do during your screen on time ?
[Galaxy Note 4 General] tmac31:
Not really, yes its cpu intensive and no its not because you dont always load something for example think this im reading this thread and it can take 15 min without even touching anything neither cpu nor data connection used in this scenario. And in pretty much every tedt you can see note 4 browsing times around 12 hours with flight mode and around 200 nits. If they are using it in home and with auto brightness it generally use way lower brightness only minus side is they dont use flight mode(i hope) and 8 hours is very possible but like i said i wouldnt call it normal usage
[Galaxy Note 4 General] POLO_i780:
You were not exactly helpful, you asked for Adb Dumpsys yet when I said I had trouble with it you were extremely rude, exactly the opposite of what a forum is for.

The screenshots, dumpsys are up, if that is not enough for you then I can't help. What I do know is that my Note 4 achieved exactly what you said it couldn't. It managed to go over 6hours SOT, with no CPU Power Saving and a whole lot of usage.

Clearly you do not like being proved wrong, you should rather just not ask for anything if your reaction is going to be filled with excuses and asking for more things you DID NOT ask for before the run was done and posted.

Cheers! :)
[Galaxy Note 4 General] gekkehenkie11:
LOL. Very convenient to cut out the important parts of the log. You're just trolling. Enjoy it.

---------- Post added at 05:40 PM ---------- Previous post was at 05:39 PM ----------

Yes, if that's your idea of normal web browsing, you should easily get past 6 hours. I think 9-10 hours should be even possible if you just stare at your web browser at lowest brightness. But most people actually do touch the screen, multiple times per minute and then you won't get past 6 hours. That's 'normal web browsing' to me. Anyway this is all getting a bit silly now.
[Galaxy Note 4 General] tmac31:
Like i said if in tests 12 hour is possible 8 hours possible too and i explain how they achive it i myself can get 6 hours only and browsing not that hard on cpu unless you keep refreshing the page every sec.
[Galaxy Note 4 General] gekkehenkie11:
But what do you do if you're not touching your screen for 15 minutes ? What kind of web browsing is that ? I'm not sure why we're even this discussing this here. This is getting really silly, I'm going to eject from the conversation at this point. Good luck !
[Galaxy Note 4 General] POLO_i780:
Been a member here too long to troll.

Try another excuse, or don't bother responding.

Convenient for you to ask for more things after all you asked for was posted.

I wouldn't even know what to cut to be honest, I was actually looking forward to your insights to explain how achieve. I usually love reading posts from you more technical guys who understand the figures.

Thanks for nothing.

---------- Post added at 06:46 PM ---------- Previous post was at 06:33 PM ----------

As far as he is concerned, web browsing means loading new pages every second. Sitting on a page for 15mins could mean you put your phone down while reading and went to do something else be it cooking, talking to someone, the bathroom etc etc... He doesn't consider what happens in real life, its all down to his "maths", no consideration of reality.
[Galaxy Note 4 General] gekkehenkie11:
LOL you keep making stuff up. I said several times, that to me 'normal web browsing' means touching the screen at least 1 time per 10 seconds. Not every second.

To people like you web browsing is touching your screen once every 15 minutes. What kind of web browsing is that ? Yeah I can get 12 hours SoT like that too.

Anyway, this discussion has gone really really down the drain ... Thanks.
[Galaxy Note 4 General] tmac31:
Lol it was just an example. 5 min or 15 min whatever you definetly not load a screen constantly. For example in the mornings i check news and i open like 10 tabs and read them later it generally take 10 min to read all of them so it doesnt count as a browsing?

Here is gsmarena test and how its done if 11 possible in some circumstances 8 hours is ofc possible. I believe samsung claims 11 hours for note 4 too.
[Galaxy Note 4 General] tmac31:
Why does touching screen worth something? In note 4 exynos it just make a53 cores to max freq and on s805 it was 1.3.1-4 ish on 2 core if im not wrong and both doesnt really mean anything very very low usage only. But loading a page takes full freq on 8 cores for exynos it should be something like that on s805 so what is the power usage difference? 1/10 or something possibly.
[Galaxy Note 4 General] gekkehenkie11:
Lollipop will scale up the CPU to the 'touch min' frequency every time you touch the screen. I don't know what that frequency is for Exynos, but for the Snapdragon that's a minimum of 1.27 ghz, every time you touch the screen. This is done to ensure smoothness of the system (reasoning of course that if you touch the screen, the system has to do things like scrolling a web page). What happens next is a result of the CPU governor and mpdecision. Most governors try to get an idea of the payload of the system and then scale up the CPU to a certain treshold. So it all depends on what happens on the screen from there on. For a web browser that usually means it has to render the whole QHD screen based on the webpage, which can be quite CPU intensive, hence scrolling a web page usually cause mpdecision to activate all 4 cores on the snapdragon and quite a few times even to the max speed of 2.7 ghz. So that just drains battery.

On the other hand if you just do nothing and just stare at the screen, mpdecision will unplug 2 of the 4 cpu cores and the CPU speed will cycle a bit on the remaining 2 cores between 300 mhz and about 1.19 ghz.

And then there's of course the fact that if you click a link wifi becomes active and active wifi is even a bigger battery drain than the CPU itself at 2.7 ghz.
[Galaxy Note 4 General] tmac31:
Yes i wrote that touching just activates cpu boost (its 1.3 on only a53 cores for exynos) same goes for hovering pen on the screen but its still way lower than an max freq. And just check the gsmarena scores at up you can see with page loading at every 10 sec with 50% brightness note 4 can get 11 hours sot. A general person does way lesser in browsing without flight mode. And 18 hours video play is possible as you see they can just push sot higher with browsing and video

Again im not saying 8 hours is possible in general usage. With mobile data(consumes way more than wifi) , phone calling, background activity while screen is off(sync content), even if you just get outside note 4 use very high brightness and even use brightness boost which only activates on high light with auto mode there is no way 8 hours is possible in daily usage. But getting a 8 hour is possible but i wouldnt call it normal usage a phone used without phone call and mobile data at outdoor doesnt worth considering.
[Galaxy Note 4 General] POLO_i780:
Oh my word, I completely forgot about GSMArena's Results :D

Yes, with the Note 4 on Lollipop 5.0.1 they got 11hours and here are their details of how they do the test:

Result and thats with a web page loading every 10seconds with 50% brightness and NO CPU Power Saving once again.

LMAO! Why did I even waste my time with dumpsys and a person who hates being proved wrong when credible reviewers proved this last year :)

Well that ends that discussion, when GSMArena could achieve 11hours, then my 7hours more than makes sense, so does Bronx's stats.

Back to normal discussions.
[Galaxy Note 4 General] gekkehenkie11:
It's about half of the Mah for full speed, but still about 5x more Mah than 300 mhz.

Loading a script every 10 seconds is an interesting idea to objectively compare results between phones, but it's VERY far from real world usage. It's quite different from interacting with the screen itself. For one the system wont scale up to 'touch min' speed (1.27 ghz). Then, reloading the same page over and over again is likely to cause caching. And note how the article says "There are no flash elements on the webpage". Why else do you think no one here is able to show proof of 6+ hours web browsing, other than that troll that's still posting but doesnt want to post proof ? If web browsing for 11 hours really would be possible, wouldnt it be really simple to post some 7+ hours log ? I can't do it for sure (unless I of course barely interact with the screen, then it's easy, or if I simply change CPU governor or put on CPU power saving mode or limit the CPU in any way). I usually have 5 hours SoT when I do web browsing (but I touch the screen about every 3 seconds, I read fast). And that's a perfectly normal result, if you see the CPU stats and log file.
[Galaxy Note 4 General] Danilo Pantelić:
Note 4 - 11h web browsing haha - party for idiots :)
