N910c. I found out that when hovering the s pen on the screen, processor cores work faster consuming more battery. I myself use the pen all the time, even for normal browsing. Monitoring the cpu when hovering the s pen on the screen I noticed that the A53 cores never go below 1300 MHz, which is their maximum frequency. I can approximately say that using fingers and not s pen gives about 1 hour of screen on time more.*

Also for those who find themselves in a bad situation on low battery and want to get the most of it, I suggest reducing the screen size to minimum using one handed input in settings. It can save a lot of battery because about half of the screen's pixels won't be lit.

Hope it helps.

Canadian Qualcomm N910W8 here. I've been getting pretty sub-par battery life since I bought this thing. 3.5 hours screen on time max. I think my android wear device being connected kills the battery more than anything but I can't be sure. I've tried better battery stats, Greenify, custom kernels, all to no avail. I'm not sure what my issue is. Maybe some of you could take a look at these screenshots and tell me why I have like 56% awake time. Seems like my device is never sleeping when the screen is off.

Thanks in advance.

I put a movie on my external SD, started to play it at 100% battery and at about 2/3rd of max brightness i only had a 18% drain after 1h40mins screen on time, which should give me 8hours of screen on time ( didnt test that yet as i dont watch movies that long). I'm running stock android, no root, nothing disabled etc.

Im still confused about how people with a oneplusone get 10h+ screen on time...
[Galaxy Note 4 General] Deni_N:
I have good deep sleep over night, but my standby time is not good, i lose about 10% battery in 7hrs standby..wifi on, no battery saving.
[Galaxy Note 4 General] dax51:
I am also having this issue when using LTE network. When I switch to GSM network, battery drain is much better at around 2%. Mine is 910G. Don't know if this is a phone problem or normal.
[Galaxy Note 4 General] Wally93:
I put mine on airplane mode at night, no powersaving mode and i lose 0-2% overnight, i see no point in leaving data or wifi on while you're asleep..

Do you use battery saving?? How do you get this much screen on time, I get arround 4h30min, 5h max.
[Galaxy Note 4 General] MEGAX91:
nope i don't use it.

just uc&uv :D

I've been experiencing quite high battery drain from android system leading to abysmal battery life

Turn of smart network switch in wifi settings
[Galaxy Note 4 General] Legatus Onoris:
I really can't understand all the reviews I've read until now(not only italian reviews, but also US, UK and so on).

All say that Note 2 incredible battery life has come back with this Note 4 but gosh, if this statement is true I'm really really unlucky.

In standby, both offline and online, the battery decreases good (this night only 1%[8hous] offline) (about 2% hour standby online with all syncs and wifi).

But when I use it, doesn't matter if I have sync on, if I have screen brightness 100% or 50% or auto, the battery goes down crazy.

I reset it 2 times for other reasons but the story is the same. I can last a day but I didn't expect to worry about battery.

I see a lot of people make 4-5 even 6 hours of screen of LOL I can make MAX MAX 3hours and half if I'm lucky.

And I've turn off some things that can bother it(smart switching, GPS is off and I turn it on only when I need it).

Don't know if it's this f****g screen that is soo pixel dens but really, i'm quite pissed off
[Galaxy Note 4 General] tanmays005:
battery life is getting better

Hi guys. When I first got my phone and I charged it to a full 100%, I was down to 4% in 4 hours and 10 minutes. The usage was somewhere between moderate and heavy ( 1 hour of web browsing, 15 minutes of Asphalt 8, 1 hour of music). I was on 3g network and I switch data on only when I'm browsing or using whatsapp. Anyway, I turned off all the useless apps (S health, S voice, Google Now, Google play books, Google play newstand etc.) and today with pretty heavy usage (30 minutes of Asphalt 8, 40 minutes of navigation, over an hour of browsing etc.) I'm down to 8% from 95% with a screen on time of 5 hours and 30 minutes. For anyone having issues with their battery, try switching off google now cards and s health if you don't really need them.

PS- Power saving mode was on both times and brightness was set to low levels (20%) and on auto at times. I also use a 16 gb micro sd card with my phone.
[Galaxy Note 4 General] DarthJe5us:
It's off.
[Galaxy Note 4 General] xishp117x:
So far on SM-910C lollipop
[Galaxy Note 4 General] Deni_N:
This is great, I fleshed Lollipop last night, i hope i can get same battery life. What is you setup, what did you turn off, do you use Battery saving?
[Galaxy Note 4 General] jdomadia:
U said your wifi is off but screen shot shows it's always on, change your settings in going to advance settings of wifi, untick always allow scanning .
[Galaxy Note 4 General] exclass:
My battery on lollipop is about 15% better than kitkat. Tested it 3 times. Stock N910c. Wifi on all the time (edit, not during night), normal usage. I wiped everything when I installed lollipop and turned off many apps I don't use.
[Galaxy Note 4 General] Deni_N:
What did you do?? I have bad battery life on lollipop. What apps did you turn off??
[Galaxy Note 4 General] xishp117x:
This was the final battery cycle, and I'll post more info later, getting late to school!
[Galaxy Note 4 General] exclass:
I don't know but I don't use hangouts or facebook's messenger so turned them off. That f*king messenger drains battery even when you don't use it. Also, that facebook app seems to be very battery hungry. Try using facebook from the stock browser (fastest browser), maybe it's more efficient. Just my opinion though, cause I dont really use facebook that much.

It's a bug of android 5.0.1. My wifi shows always on too, when definitely it's not. Happened to me with a cm12 rom on another phone too.
[Galaxy Note 4 General] jesusotero1234:
what about charging time? it is true it charges 50% en 30 minutes?:eek:
[Galaxy Note 4 General] _INSPIREed:
Battery life quick review. Worth a good look. User shows different types of usage and the up times with screen on time

[Galaxy Note 4 General] patriotaki:
Impressive.. Lets say you use your note 4 for social networks only for about 2-3 hours total time and when you dont use it you have the wifi off

How much do you expect the battery life will hang on?
[Galaxy Note 4 General] _INSPIREed:
If the note 4 battery life is at least equal to the note 3, I've reached 8 hours total screen time , with about 2 days of uptime. And this looks to be true. You could easily get over a day with that usage, you know depending on screen brightness, signal strength and such. I'll be sure to test the note 4 on the 17th when I get mine.

exynos version
[Galaxy Note 4 General] romreviewer:
What about the screen-on time with stock Note 4 ROM ?
[Galaxy Note 4 General] MGS88:
this is SN805 version

till now SN805 proves to be better battery life with almost less 20%-25% performance than exynos's version
[Galaxy Note 4 General] tmac31:
s805 version from MKBHD , people reporting very different battery lifes in both version. some say 5-6 hours some 3 hours.

https://twitter.com/MKBHD/status/520931524712341504

3 hour SOT in this pic by MKBHD
[Galaxy Note 4 General] _INSPIREed:
The whole debate about performance between SN805 and Exynos5430 is mute to me. Yeah its a noticeable difference in benchmarks, but that performance boost in every day use wont be noticed. Not unless you do high intensive gaming or emulation you might squeeze a few frames out. And I'm still not convinced on it being so much better for android L except possibly a little better in battery life, and possibly better app launching once all apps are updated

Battery life depends from user to user. Personally, I think its good you at least see that there are users who can get 6+ hours screen on time and those who don't. Cellular signal, screen brightness, connections used and app awareness (wakelocks etc) all effect battery life severely
[Galaxy Note 4 General] tmac31:
yeah but they are reviewers so they should know how to sort things out. and give us similar scenario battery usages.

and about exynos vs snapdragon . exynos is a better processor as 32 bit too but i would go with whatever samsung brings to my country. it will be very similar.
[Galaxy Note 4 General] MGS88:
totally agree with that

all I want is best battery life and just smooth performance which I believe that what Qualcom's offer
[Galaxy Note 4 General] _INSPIREed:
Yeah man that's true. Sadly though, a lot of these reviewers are just that, reviewers, and wouldn't know much about maximizing battery like the likes of people you would find on xda. The majority of their viewers are average consumers who just power there phone on and go, so they cater to those people. Not those who actively monitor what settings are on, what processes are running, or those who even go the extra mile and root to debloat system app, greenify things, change app persmissions etc. These are all things I do and have never seen a reviewer go over these and I consistently get good battery life on all devices with a lot of use.
[Galaxy Note 4 General] tmac31:
True..

And he said snapdragin before but he changed to exynos version. There is like 4 people reviewing exynos version on u.s at&t lte and problems seems with 3 of them says bad 1 said great(over 6 hours sot).

I checked exynos lte bands and it doesnt offer same lte bands with at&t so its mainly their problem and they said they gonna check that. Lte connection probably having issues thats why people reporting great result with exynos in xda.

I dont even know how they use lte on at&t with exynos lol.

Both version will be very similar in battery like russian reviewers mentioned.
[Galaxy Note 4 General] jesusotero1234:
thanks but i see that the battery last like note 3 that is good for me, but i want to know if the phone really charges from 0% to 50% in half hour that would be really interesting
[Galaxy Note 4 General] chong67:
Going to get my Note 4 at the UPS call center this Monday when it open.

When is the Anker battery coming out?

Do I need to get a battery with NFC?
[Galaxy Note 4 General] 2ndammendment:
If you are actually able to pick it up Monday let us know. I was told by carriers that regardless of what it says people won't be getting them delivered before the 17th.
[Galaxy Note 4 General] GSeeker:
I got the exynos version, SOT is about 4 hours which is bad actually.:eek:
[Galaxy Note 4 General] EP2008:
Did you do anything to optimize it? Disabled any bloat? Greenify stuff? Etc...
[Galaxy Note 4 General] GSeeker:
I did disable a few apps, no root. No greenify.

Go to T-mobile forum here and you can see. Most people at T-mobile get theirs this Mon. They upgrade everyone to next day saver. ATT is next Fri. Verizon a week later.
[Galaxy Note 4 General] Deni_N:
i will try to do factory reset, on kitkat with same apps i had 5h screen on, on lollipop, i can barely get 4h :((
[Galaxy Note 4 General] jdomadia:
This is there even in kitkat, its just a settings u need to turn off, even if your wifi is offf it will show u ON if in advance settings "ALWAYS SCANNING" is on.
[Galaxy Note 4 General] exclass:
It's not it dude. That option is disabled. Wifi still shows on. Its a bug.
[Galaxy Note 4 General] POLO_i780:
Updated my N910F to 5.0.1 yesterday, doing my own little battery test today.

So far:

Battery at 35%

13h43m

6h18m SOT.... I'm very happy.
[Galaxy Note 4 General] Deni_N:
What did you turn off, i have awakes, on lollipop, my battery life is avrage, 5h SOT...my model is 910C.
[Galaxy Note 4 General] POLO_i780:
Same setup as I had with KitKat.

Display: 35%, use Auto when I go outdoors.

GPS: Power Save (using WiFi and Mobile Networks)

I am connected WiFi in most places I go and have decent network signal.

NFC Off as I never use it.

I don't seem to have any unplanned wake ups.
[Galaxy Note 4 General] tmac31:
With that signal strenght and wakelocks if you are getting 5h its awesome...
[Galaxy Note 4 General] Deni_N:
How can I monitor wakelocks?? As of bad reception, I will use edge where I dont have good HSPA reception.
[Galaxy Note 4 General] POLO_i780:
I leave my phone in LTE/HSDPA/EDGE Auto Connect, or on HSDPA/EDGE Auto Connect, I never leave it in EDGE Only, I tried it a few times and I actually found that it ate more batt in EDGE Only mode, my work has great LTE coverage, but home has no LTE coverage but excellent HSDPA+ coverage. Even in areas with bad LTE OR HSDPA the antenna seems to do a great job in running as efficiently as possible, but mine is the N910F, the C may work a little differently.
[Galaxy Note 4 General] bekasulaberidze:
Battery life is very poor drains very very fast, and charges from 10% to 100% in one hour (no fast charging) regular use no wifi no gps just messaging drops from 100% to 70% in 2 hours, I don't think that this is normal.
[Galaxy Note 4 General] POLO_i780:
Well am thoroughly impressed with my N910F's battery life on 5.0.1 and off to bed now.

Results:

Battery: 7%

Off charge: 16h13m

SOT: 8h35m
[Galaxy Note 4 General] Kyrillos:
Guys please see my stats. For some reasons i am not getting sot even close to what you guys getting.
[Galaxy Note 4 General] djdurance:
Google Play Services

Anyone else have Google Play Services having a battery drain? This often will match my screen usage. I have done two resets with no avail.

Note 910c with Lollipop. Happened on 4 Kitkat as well.
[Galaxy Note 4 General] cricketgirl90:
How???
[Galaxy Note 4 General] djdurance:
These look pretty good actually. You have 32 hours of standby which will account for likely 50% of your battery life there.
[Galaxy Note 4 General] Kyrillos:
Thanks. I was a bit worried sonce everybody refer to sot time way higher than mine. I end up have more % spent on my network reception and other. :)
[Galaxy Note 4 General] rhadoo_ds:
I am in a similar situation, 910F.

Still, battery life is OK :)

[Galaxy Note 4 General] rhadoo_ds:
Final update. Best SOT that i ever had, still with the drain from Google Play Services.
[Galaxy Note 4 General] IronMaidenBG:
I noticed that in the evening if I put the phone to the charger without restarting after pulling off the cable, it drains about 10% until dawn. If I restart the device after charging it drains about 2%.

What would be the conclusion from this experience?
[Galaxy Note 4 General] bekasulaberidze:
what about this ? normal usage and min. brightness
[Galaxy Note 4 General] VuBoo:
:o hooooooow?
[Galaxy Note 4 General] rhadoo_ds:
Frozen unnecessary bloat, kept only what i need, stock, light auto2, wifi only when needed, 3g full time, sync on full time
[Galaxy Note 4 General] Kyrillos:
Is 3g consuming less energy than wifi?
[Galaxy Note 4 General] pedmond:
No, more...
[Galaxy Note 4 General] The_MutenRoshi:
Mine is getting almost 5h screen time! N910F Stock!
[Galaxy Note 4 General] GeorgEveS:
what's wrong ?

I did a full wipe when upgrading and now this ?

Anyone have any ideas why this is happening ? Or how might I fix it ?

SOT is 50 minutes and Spotify says 2.5 hours total connection time ( I listened to it about 30 minutes )

and I haven't used Fenix at all today...
[Galaxy Note 4 General] iridaki:
I don't think full wipe or no wipe makes any difference. I find that Lollipop still has some serious battery and memory issues, which hopefully Google will resolve in the upcoming 5.1 update and Samsung will implement them soon enough after.
[Galaxy Note 4 General] djdurance:
Seemingly significant difference in battery life

I moved from using high accuracy to GPS only mode for location... Seems to have increased my battery life and decreased my wake time with screen of...

I actually noticed a big difference the wrong way using power saver mode for location.
[Galaxy Note 4 General] iridaki:
After updating to Lollipop, I found that the phone behaves very differently. I have high "stay awake" times, caused by Android OS, even on Ultra Power Saving Mode. However, screen on time is still close to 4 hours, which is what I was getting on KK with my usage.

Before people jump in and say I need go factory reset, no I don't, there's another Note 4 in my home right now that was wiped before and after the update and shows the same symptoms.

Also I did install Gsam, but I'm not rooted, so it didn't give me more information than the stock battery stats page.
[Galaxy Note 4 General] Deni_N:
I have this problem on lollipop, constant awakeing... my battery life iz around 4h screen on time.. i did reset, and i cant get it to work as it should.

Please, help..
[Galaxy Note 4 General] jonneymendoza:
How can I get back root after getting lollipop? Root gives me access to proper battery stats!
[Galaxy Note 4 General] bonerp:
My battery is definately better but wifi appears always in use, even though its not.

I've tried a couple of apps that are supposed to switch off wifi based on location but I can't work them out - too complicated and poorly written english.

Can anyone suggest a good app to turn off wifi connection attempts by location?

What I am looking for is when at work, wifi is always off. I'm happy for it to search when in town or at home though.

thanks
[Galaxy Note 4 General] deep!:
I think it is bug on battery stats screen, As i switch off wifi when i leave home but it appears to be on in battery stats all day even though it is off.

But if you check with GSAM it shows the correct time of wifi active, so for me it seems to be bug and also not causing battery drain, battery is even better than kitkat.
[Galaxy Note 4 General] clintonroche:
Most likely you can't.... Unless you have an unlocked bootloader.
[Galaxy Note 4 General] jonneymendoza:
I did unlocked my bootloader!

did the official rom i installed lock it again?
[Galaxy Note 4 General] clintonroche:
A little off topic... but if your bootloader is officially unlocked. you can root easy. I would suggest checking in the development forum for your device.
[Galaxy Note 4 General] jonneymendoza:
Will check it out thanks!
[Galaxy Note 4 General] The_MutenRoshi:
Check out my battery usage. Still kitkat stock no root! 5h screen time.
[Galaxy Note 4 General] cathain:
Is there any guide on how to improve battery life? I've never had good battery life, on average about 3hrs SOT by time I get down to 15% from a full charge? I can't understand how people get are getting anything over 4hrs SOT!? Since last full charge I am down to 50% and only 1hr SOT. I'm running stock and have GPS and bluetooth always disabled. I am syncing 2 gmail and 1 outlook account. I had greenify installed and hibernating some apps but I found it actually caused even more battery drain?? Is there anything I can do?
[Galaxy Note 4 General] deep!:
I constantly get 5 hrs+ SOT, even better on Lollipop, I have Gps ON all time( Power saving mode), wifi as needed, sync 2 gmails, what i have done.

Disable all bloatware like chaton, unified daemon, samsung link, google playstand etc which i don't use.

I use greenify to hibernate most apps, like Facebook, messenger etc, i was hibernating system apps too but that caused more battery drain as Android system have to restart them all time which cause more drain, idea is to hibernate only system apps which you see doesn't always start up automatically, the only system apps i have hibernated now is Samsung push service ( huge drain) and gear vr.

I also have hibernation+lock screen shortcut on my home screen so when i am done, i press it, it hibernates apps and lock the screen.

I have also noticed google now is big drain so have it disabled with location reporting off too. Hope this helps.
[Galaxy Note 4 General] soralalp:
Hello mates,

I turn on location and set it to power saving. Then I turn it off and turn back on and it sets to high accuracy automatically. What might be the problem? Also when I charge my battery to full and leave the phone locked overnight, it drains 1% per hour. I am using exynos on lollipop.
[Galaxy Note 4 General] ludovicianul:
HI guys,

Just wanted to share my experience. I've had very poor battery life until 2 days ago. My battery wouldn't last not even for a day. I've uninstalled Facebook and Facebook Messenger and my battery is great now. 24h since unplugged, 2h SOT and 42% left. Just try to uninstall Facebook and see what happens. ;)
[Galaxy Note 4 General] thetonyclifton:
I dislike Facebook's imposed messenger so I uninstalled both apps and put a link to the mobile site on my homescreen, - all problems solved and battery saved.
[Galaxy Note 4 General] iridaki:
UPDATE: I think I found the culprit. It's the WiFi. What I did today was charge my phone to 100%, switch WiFi off, disconnect from the charger and reboot. Then went about using it as usual, only I didn't turn WiFi on at all, not even for a second (weirdly enough, the battery stats report WiFi being on briefly at times, but that's another Lollipop bug).

The results were a big increase of SOT (+1 hour, see my previous post for comparison), no more permanent wakelock and increased standby time.

My findings are consistent with reports from Nexus users, claiming WiFi on Lollipop is a battery killer, even on 5.0.1, which was supposed to be an update to fix said issue.

Now, not turning on the WiFi is not really a viable solution for me, as I don't have an unlimited data plan, so I sure hope Samsung will fix this problem soon.
[Galaxy Note 4 General] bekasulaberidze:
what about my poor battery ? drains very fast, greenified everything, it's stock kitkat, or tell me what to freeze I charge this thing twice a day, everything is turned off - wifi sync nfc... regular usage just facebook for 15 minutes or 9gag, brightness at 10% any suggestions ???
[Galaxy Note 4 General] aartvv:
Stock lollipop rom not rooted.Always wifi or 4g only at night i switch them off.Gps and location off.Screen brightness auto+10.Disabled some bloatware.Sot with lollipop is similar with the sot i experienced on kk.

If you have poor battery life with high wake up time without clear reason, you might try to remove external SD card and check if it helps. Not sure it happens with all cards but this solved my problem.
[Galaxy Note 4 General] iridaki:
Seems unlikely to be related, but not entirely impossible. What kind of improvement did you notice after you removed the SD card? Do you have before/after screenshots, numbers, anything?
