I am lost for words, my friends. This morning I unplugged my N4 after charging over night and I just left it sit on my bed with wifi on. After 4 hrs I finally needed to check something on my phone and to my awful surprise, the battery went down from 100% to 21%. I have frozen every single little bloat on my phone and I'm running stock 5.0 with root ofc. It was already bad on KK with an average of 3hrs SoT, but this is just over the top... Media server with no mercy.

Someone apps drain your battery check your apps,hard reset and be careful what apps you download don't have this issue anytime.

I am getting over 6 hours sot stock kit Kat connected to my gear s all day - hopefully it doesn't get worse when I finally get the lollipop update!
[Galaxy Note 4 General] BlackCrow-It:
Hello everyone! I've got this phone for a while. During the first charge, the snapdragon edition, had a very long battery. Sot around 6/7h using gps sincro wifi 3G email etc, and with a normal use I got 7h and 45m. But after that week, the screen on time goes down suddenly, 4SOT if I was luck. I did a factory reset and during the first time i got 5h SOT (with 20% remaining). I though it was improving a little even if it wasn't the same result that I got. Anyway, right now I have the same problem. I use facebook and other few apps. Screen is around 20% and android sistem 16%. When I have time, I'll post some screen.

What do you all think about this?

ps. sorry for my little english, I'm improving it!

I solved my issue with the bluetooth test apk, i rooted my phone and disabled it, no matter how may time i wipe and flash the stock firwmare, it does not make the problem go away. Now in 5 hours i lose 1% during sleep.
[Galaxy Note 4 General] patriotaki:
Lost 11% last night..is anything wrong?
[Galaxy Note 4 General] Kernel ranger:
Let me guess you already own an Exynos :laugh:, Sorry boy, hard facts are hard facts, am not the one who did the review and it's not the only review that stands with those facts. Your comment is like a headless creature......dead!
[Galaxy Note 4 General] POLO_i780:
Thanks for this, a great read.

For me, battery life trumps all, it is all I ask for in a phone, a battery that can do at least 12hours of heavy usage and at least 6hours SOT, now with Lollipop my Note 4 SD gets over 8hours. The phone runs fine, if I wanted brute performance for gaming I wouldn't bother with Android, this is why I have an iPad, iOS remains the best mobile gaming platform, my old iPad 4 runs the heaviest of games such as Real Racing at full FPS for extremely long periods as the games are well optimized. I see no point in the Exynos minor performance advantage as it pays for it in battery life and the whole 64bit thing is just laughable, I cannot believe it is still being pushed as an advantage when the phone can't even take advantage of it but anyway, it is what it is.

The Note 5 will be here later this year, no point in all this, enjoy your Note 4s whatever variant you have, as they are all beasts and the very best Phablet money can buy right now.
[Galaxy Note 4 General] Ausboy 2011:
So very 1 sided my friend. Also before you say anymore about 64 bit and it not helping unless 4gb of ram is in the device. You need to to a bit of reasarch into 64 bit and its effects for android.
[Galaxy Note 4 General] tmac31:
64 bit worth nothing but whole tests done by phonearena are wrong. snapdragon cant rival exynos in cpu exynos 5433 is even faster than s810 in cpu. and 4 gb isnt related with 64 bit. whole armv8 advantages there for exynos. im using note edge s8-05 for 2 weeks and exynos note 4 together sorry but battery is on par. and performance and heat advantage is very obvious for exynos.
[Galaxy Note 4 General] POLO_i780:
You have just contradicted yourself.

So your Note 4 Exynos has equal battery life to the SD Note Edge, yeah? Are you aware of the fact that the Edge has a battery that is 220mAh less than the Note 4? So in other words, the SD Note Edge despite having a smaller battery matches the Exynos Note 4.

You have just spoken volumes about the Note 4 SD vs. Exynos.
[Galaxy Note 4 General] tmac31:
Well i was expecting this when i wrote that. Note edge cant pass 5.5 hours sot. Note 4 is 6-7 hours. So i said they are on par. Note 4 snapdragon should be getting around 6-7 hours too.
[Galaxy Note 4 General] POLO_i780:
So you are back paddling now.

5.5h SOT and 6-7h are not on par. BTW I have a SD Note 4 and on Lollipop I'm getting around 8h SOT instead of 6-7h, and from what I am seeing and what AnandTech said, the SD Note 4 does seem to get better battery life.
[Galaxy Note 4 General] tmac31:
Seriously? I m getting 5.5 hours on edge. So i eliminated battery disadvantage and i said they are on par whats wrong about it? 220 mah cant give 3 hours sot....

And anandtech or other sites generaly test spesific scenarios. Like i never use wifi and i use pedometer on both. Or i auto brightness no power saving 3 hours talk time atleast etc. In my same usage pattern. Thats what im getting and in comparing kitkat btw i never said its lolipop. You are getting 8 hours its good you can get 12 hours too if you just surf in internet too with wifi. im saying what i get. With both phones. Snapdragon can get better times dunno but there isnt hours of difference im sure about it. 1 thing i notice exynos use cpu more agressive too.

Ps :anandtech shows 6 plus has better battery than note 4 too. I was using it before note edge its definetly not. Its worse
[Galaxy Note 4 General] Kernel ranger:
The problem I have with that is that the theoretical projection of what 64bit should be over 32bit on paper never matches the real world result. So nothing like future proofing. You will not get twice the performance output only a small boost over it which isn't significant enough to ditch the 32bit device.

What you don't realize is phonearena isn't the only one reflecting these results, you just haven't looked around at other benches and endusers who use it as a daily driver actual experiences on youtube. See ... if you refute a comment without anything tangible to backup your claims, your comment is as good as just spit-balling for the sake of it.
[Galaxy Note 4 General] tmac31:
Its a battery thread so i wont ruin it. I have both devices phonearena scores just wrong. Check anandtech review if you want. There is atleast 20% cpu power difference between(as 32 bit its not a possible power its like that now) 1 more thing about your older post too actualy snapdragon has faster ram its that wronng what phonearen claims.

Ill post exynos 5433 geekbench scores its even faster than s810 and quallcom says s810 is 20-25% faster than s805 and you say 5433 only 3% faster good thing. I wont post something about that again 5433 is definetly a 1 generation newer soc with way better cpu. We talked about that too long(just read closed thread from start) But it doesnt mean s805 is bad. Its still a fast soc you should be happy about it. Im testing it on note edge.its slower but acceptable bigger problem is heat.
[Galaxy Note 4 General] Kernel ranger:
Now this is what I call a comparison side by side :- https://www.youtube.com/watch?v=83Hkb3FAncc and not just throwing claims of this and that.

Again no way the 64bit is going to be running on 5433:- http://www.tomshardware.com/news/samsung-note-exynos-snapdragon-armv8,27688.html

It is also interesting you say nothing about the 5433's battery life (which is the most important factor in this thread considering the performance difference isn't enough to impact notably in real life situations unless you just want to bench all day) but very quick to shoot down the s805 with heating issues. You simply sound so biased. A phone that gives significantly longer battery life for a 3-13% less performance is far better and a preferred choice in my books. The fastest isn't always the best. Since you are so insistent that phonearena are wrong, all you have is just claims that have no backup to support it. If you want us to believe so, give us at the least 3 independent sources apart from yourself proving your findings and claims to be true, so your post alone isn't enough. It is very easy to say anything if you don't have to prove it.

https://m.youtube.com/watch?v=K4__rbWOGB4

here is s6 and s5 difference i dont know what are you expecting from a 1 generation newer cpu. this speed difference is there for exynos note 4 and s805 note 4 too. you can stay with s805 forever but stop living in a dream. samsung claims s805 note 4 has 7% battery difference than s800 note 3. which i have and best battery s800 note 3 can give 6 hours sot. and i say snapdragon note 4 can get 7 hours which is possible for exynos note 4 too. and i have both versions(1 is note edge) i dont have to believe phonearena bull**** sorry. snapdragon version has double ram speed than exynos note 4 and phonearena shows exynos is better its just fails. and like i said 5433 is full armv8 cpu 64 bit doesnt matter.

[MENTION=5226195]tmac31[/MENTION]

I just want to say, even if you have the Note Edge, websites such as GSarena and Phonearena all report vastly different battery times. So its not a good comparison between your exynos and note 4 Edge same as the note 3. Also I may get it wrong, but no one is dismissing exynos performance. That said, speaking about performance with Lollipop coming (jn the next 10 years or so 'sigh), and people reporting their Nexus Phone being more fast and smooth in 5.1 I presume. It might be that the snapdragon will be just as smooth as the exynos in the future as well. Apple so far has proven you don't need to have a beastly spec phone for it to be smooth and fast.

Finally generally speaking, unless you have the note 4 snapdragon, comparisons between battery life between other phones is not accurate enough to give a conclusion on which "version" of the Note 4 is better in all categories whether speed or battery. Even so if you do have the Note 4 Snapdragon, its just a personal conclusion, and not necessarily an objective one but better than comparing two completely different phones. "See the anandtech article of the note 4 snapdragon vs exynos", that article is the definition of objective, and backs up what many people who have both devices say about their battery difference.

Of course if you can show some factual objective information, all the good to you. More objective information on the exynos vs snapdragon battery life and differences between each version is all the better for potential buyers of both who can choose. :good:

This is part of the reason I dismiss post like yours when comparing both versions, firstly everyone have different usage, and on top of that some people live in an area with good or bad signal, and so report vastly different battery times even despite having the exact same version. One of the only good comparisons is when people have both, but again its not accurate since experience may again vary on both but still much better since there is a direct comparison. However if you pool all the people with both and their reported battery times you get a better example because its simply a form of simple meta-analysis.
[Galaxy Note 4 General] Cosmos81:
Personally I do find, that as we are talking about SOT (scores) there should always been, screenshots with it, otherwise the SOT (scores) are meaningless to me, because we are all using our devices differently.

I read already a lot of reviews & threads (here) about the battery-life of the Note 4 to me the review from Anadtech is one of the most informative,s.

I have chosen for the N910F mainly for the, better graphics and off- course for the better battery-life for my kind of usage, I was in doubt for the N910C as it is much faster but and the end of the day, I rather prefer a better battery-life over speed.

In the web-browsing battery-life benchmark (Wifi) the Exynos comes out 79 minutes shorter than the Qualcomm version, I do find that quit a lot.

[Galaxy Note 4 General] golfinggino:
I would like to see a screen shot of that, I have a friend like that has the screen set to 10 minutes and never uses the phone lol
[Galaxy Note 4 General] tmac31:
well im getting 5.5 hour sot on edge. and im adding 1-1.5 hours sot for note 4 its quiet alot for 220 mah difference but its ok. problem is i have note 4 exynos and snapdragon edge so its basically same usage pattern of mine there is no difference. and im not saying quallcom is bad on battery it could be better but there isnt big difference in daily usage. im saying it changes from user to user but half an hour will,be most difference between them im sure about it.

and about performance yes there is a very noticable differenece but it doesnt make snapdragon slow. worst part about it is heat. and stutters in scrolling. app opening cant be that different s3 is opening apps fast enough too.

about battery tests i dont know how they do browsing tesfs but exynos is very agressive on cpu usage. a53 cores always ready and on full frequency if you are touching screen. a57 cores can be on 800mhz and 8cores running while scrolling but basically whenever you touch screen no matter what you do a53 cores are on 1300 mhz witn 4 cores. but snapdragon version is only using 1300 mhz on 2 cores.

samsungs own reports for both of them on battery is very similar too.
[Galaxy Note 4 General] tempsgk:
Not sure what you are trying to say, but I can comment on your note 4 edge vs Exynos note 4 on SOT. I think one of the reasons for the difference in battery life between both is partly because in the note edge there is more screen size, and on top it renders more pixels and obviously having less battery to boot. Again that is just a glimpse by comparing both versions based on specs and this is likely why benchmarks such as in phonearena and gsarena show a difference.

So to put it short It is pretty much expected whether exynos or snapdragon note 4, both will be better in battery life than the note edge but its not a good comparison to make of Snapdragon note 4 vs exynos note 4 because again it brings up what I'm saying on objective and personal opinion. E.g even if you have both versions its still not enough unless many people are saying what you say and quite a lot of people say the snapdragon is better on battery life in the XDA thread with over 200 posts. But you have neither so the comparison is less valid.

And yeah the Snapdragon isn't that bad in performance as the exynos in real life usage, e.g exynos might be faster but generally the snapdragon is fast enough that you don't really notice or notice but its not as severe in comparison to other phones.
[Galaxy Note 4 General] tmac31:
So you are saying a very little screen and 220mah battery difference makes 3 hours of sot difference? Snapdragon can be better on battery but its not a big difference like you think with my usage its pretty much same.

Here is samsungs own stats. Basically biggest difference on audio playback
[Galaxy Note 4 General] tempsgk:
No I'm not saying that, I specifically mention a "difference" no where did I mention "big" difference nor did I quantify the "amount" of difference anywhere in my post.

Please read carefully.

Also on why I did not mention "big" difference, it is simply because what you say is very personal, I do not know how you use your phone, hell you might use your note 4 Edge differently than your note 4 exynos, I do not know, you might be faking it for all I care. You generally need more people giving this kind of detail to form a meta-analysis on the difference between Note 4 Edge vs Note 4 Exynos. So that is why I don't comment on "big" difference but rather "difference". However if you want an objective analysis of the "amount" of difference, go look at gsarena and phone arena and compare the two, and not rely solely on personal opinion.

Also thank-you for showing me the difference in the images which I already know and don't trust because Samsung is reviewing it and I do not know their testing methodology, its even more unreliable than GSARENA or PHONEARENA or Anandtech test. If you are into PC Gaming, Nvida or AMD often come up with benchmark charts when they annouce a new GPU, no one trust it because its inaccurate to hell. Stop trusting samsung word 100% and learn to look for other sources.

One more thing, are you talking about the Snapdragon Note 4 "EDGE" OR THE Snapdragon Note 4? There is a big difference between the two. The topic we are discussing now is about comparing the Note 4 Snapdragon to the Exynos Variant, not comparing Note 4 Snapdragon EDGE to Exynos Note because their incomparable. Did you even read what I posted? And you mentioning a difference of 3 hours sot when you only mention

Where did you pull the 3 Hours sot from?

And Final Note

STOP COMPARING your NOTE 4 EDGE to your NOTE 4 EXYNOS when making conclusions if the Note 4 Snapdragon is worst/better than the Note 4 Exynos they are INCOMPARABLE period. If you want to ask why? Re-read all my post seriously.
[Galaxy Note 4 General] Kernel ranger:
Unfortunately for someone who has read my point previously, you just don't seem to be getting it at all!! That video just proves what I said! The difference is a fraction of a second and only notable difference is when you are benching all day just to console yourself that yours is by a very long shot a faster phone just checking out trivial delays for most of the time. Fractions of seconds aren't worth upto 2-3hrs battery life difference (as reported here) except a few exceptions here and there. Again it's also unfortunate you seem overly fixated on phonearena results when I have mentioned other peoples findings in this forum too. Anyway looks like am now flogging a dead horse on this one with you. I WILL NOT respond to any of your persistent comments regarding that any more. I really hope that is clear enough for you to grasp.

I stand corrected there, the ram shown there is twice as better. Am going to keep tallying peoples report here and see what majority say from their real world experience because I know design specifications aren't always pitch perfect, there will be some with exception performance (cream of the crop) over others but majority get to have the final say. I do agree reviews can be flawed but not end user experience. Benchmarks are good, they give us a good idea of what to expect from the phone and are optimized to bench but even better if you can have a real world experience because benches and real world are two very different applications. I also see some commenter right at the bottom of the reviews say they would have also preferred battery life statistics which essentially is the most relevant bench to this thread.

I bought my note 4 yesterday and i came to this thread to find how to improve the battery life but all I'm reading is exynos is better than sd or sd is better than exynos. Useless posts for the last few pages.

All i can say is the battery on now 4 on kk is crap compared to now 3 on lollipop. Just over 2 hours and 30% gone. ..haven't even setup all the accounts to sync either yet.

[Galaxy Note 4 General] electech13:
Was a bit surprised by my battery life today. I'm a heavy user but am very happy with the life I get on my Note4 battery. I charge every night but typically have 25%+ left and use 6hrs sot. Use cell radio and WiFi all day and Bluetooth usually 2 hours.

I do typically use lowest brightness level a fair bit and at night in my dark room go even lower with night mode apps (to get even lower brightness then stock will go) as in the dark one can easily go much lower the minimum on the phones brightness and see great, especially on white backgrounds and browsing etc.

Today however I unplugged around 7am, was on the phone almost 3/4 of the day (17hrs with over 11hrs sot), used Bluetooth over 1.5 hrs, video about 2.5 and lots of browsing and Forums and just plugged.in with 7% left after almost 17hrs...

Very impressed that I got over 11hrs sot with high use.

I know it's typically good for me but this seemed even better then I expected now that I actually tracked and looked into it today.

Stock rooted 4.4.4 with no uv atm and interactive gov and no cpu tweaking.

Currently still using my Note 4 as my daily but may switch back to my Nexus 6 now that LP 5.1 has been pushed out.

I have no idea how people are achieving those battery life stats. My phone barely gets pas 3.5 sot and 12 hrs of use.

My record was 19hrs with just under two hrs of sot with most of the day of battery saving mode. Even after a fresh factory reset and no apps accounts synced my battery dropped to 50% after 3 hrs / 2.5 hrs of sot
