What is typical Galaxy Note 4 battery performance?

What is the typical battery life / performance for Galaxy Note 4 users on this board? And what is the typical life advertised by Samsung, and featured in reviews?
I get about 13-15 hours, with 3 hours screentime on my Korean Note 4 (sm-n910k). But I thought I'd seen reviews boasting near two day usage...six-ten hours screentime.
What is going on then for me? I am BITTERLY disappointed with battery performance: The attached screenshot shows my typical day. Is this normal for you too?
In this screenshot example no calls made during the day, no GPS usage, and almost no apps beyond Gmail and Twitter. I have just a handful of additional apps installed, but the phone does however appear loaded with bloatware.
I took the device to Samsung Service Center in Seoul on the weekend (for a second time) and showed them the problem. It drained 5% from 15 mins of screentime right in front of the engineer.
After resets and reboots engineer said this was normal and that all tests showed the phone to be normal.
Or is it only normal for the Korean variant, but NOT for the international variant?
Help much appreciated!

Mine from Korea too 910L
And I haven't use 3g that day, only play some heavy graphic game 45 minutes and use wifi

I got both the SM-N910K an the SM-N910C at home, mostly because at first my 910K did not want to enable 4G in my country no matter what (even though it was supposed to be supported) So when we got the local 910c i got one too. It turned out that after a firmware update, my 910K started working in LTE in Brazil normally, i dont know why. But what shocked me was the terrible battery life of the K in comparison to the C. SO i swapped their batteries to see if it was a battery issue but the C kept maintaining amazing battery life. So I rooted the K, replaced the rom with a custom N910S rom that i found online (it works just fine because they are identical) and begun deleting crap that i knew was unneeded because my C didn´t have it and while i am still running some tests it would seem that the battery life of the K has been improving. There are a ton of bundled crap inside the firmware, even the custom one...so hang on to your K, once a decent custom rom comes out of it, it will be a lot better. Mind you, i also compared them a bit and the screen on the K seems better than the C when it comes to color fidelity (the C is a bit warmer), and going thru benchmarks, the K always pulls ahead by a bit. It´s almost as if it was clocked a wee bit higher. Keep digging!

N910H with N910C SweetRom v2
12-15hrs autonomy, 5h30 to 6h of screen on time. 50% WiFi, 50% HSPA+.
Disappointed a bit because I expected an improvement over Note 3 and it's not the case at all.
OP, something is wrong there try a factory reset or a custom ROM. Root and install a wakelock detector to figure out what's happening

Thanks for the feedback. What are others getting in terms of time?
Especially interested in non korean models.

How to fix Battery Drain on the S7

REQUIRES ROOT
So some of the users of the S7 and S7 Edge are saying they are getting below 4 or 5 hours of SOT with normal use. Today, I have a solution that worked for me and I hope it will work for you. I only own a Exynos S7 and so I'm not sure if it will work for other devices. But do try it out if you are getting bad battery life.
Remember try this ONLY if you are getting bad battery life. If you are getting good (5 or 6+ SOT S7) battery life then you are okay.
First of all, I would assume you are using some kind of battery life saving app (because who doesn't want better battery life) like Naptime, Power nap, Amplify, Greenify, etc. Now just uninstall of all the Power saving apps. This may sound bad, but trust me.
Next, install a custom kernel. I would recommend Modified Stock kernel as it's not over clocked and Prometheus kernel as you can under volt the CPU. Do not over clock the CPU if you do not need to.
Lastly use the smart manager in the S7. Settings-> Battery->App Power Saving and select the apps to save battery.
Let the phone go through a few cycles before reporting back
Let me know if I helped you and a 'Thanksâ?? would be appreciated.

I'm on S7.

looks nice, but you forgot to mention that the phone needs be rooted...

No you are not, you are on S7 edge and most likely looking at a black screen for 4 hours.

Cause you have 4 hours SOT with 55% left and 6 hours use. There's no way to get that SOT unless you have it in airplane mode with minimum brightness starring at a black screen. And I thought it was the edge cause of the white thingy on the right that the edge have.

You were watching Netflix for 4 hours and yet the Netflix app is not in first 2 places? Assuming the Netflix app is third at best then that means that it has less than 11% (Android System). You could be right but I doubt it, I'd love to see a screenshot from when you get at 15% with total SOT and the apps that were used.

How is standby battery life on Exynos S8?

In my experience, especially on 4G LTE, Samsung standby is rather poor. How would you say the Exynos S8 does?

First 2 days mine was poor. But that was because I used smart switch to get everything from my S6. Then I realised battery drained fast. So I hard reset the phone again and installed all over. Just copied the video's and pics afterwards. Now the battery life is great. I don't know the screen on time because I keep the battery between 30% and 80%. But still I start use it at 80% and at the end of the day it is around 30%.

What theme is that?

I just got 43 hours total and 6.5 hours of SOT.
Best power efficiency I've ever seen in a phone.
Also read something online that the battery should retain about 95% of charge after a year of use. Hopefully this holds up!!!

8+ theme is mat black

Up.
How does the battery life of the S8 Exynos compare to the S7 Exynos , I plan to upgrade soon, just wanted to know if it worsened or anything due to the bigger display
Thanks!

Sweet! How about standby time? Overnight possibly with Wifi off?
Thanks!

Standby time never was a big quality on Android in general and Samsung in particular. iOS does a much better job in that chapter.

Amazing battery life - 48hrs including 6 hours screen on time

Just fitted a new Patona S7 edge battery and combined a few software mods I got over 2days and 6 hours SOT out of the first charge. Totally insane considering I was getting about 18 hours and 4 hours before on a Vhbw S7e battery.
These stats are on normal mode (ie not power saving) with Bluetooth and wifi on. GPS on battery saving though and WiFi scanning turned off. I'm using an s8+ port with greenify and forcedoze.

Dude that's awsome
What about back cover does it fit perfectly or is bubbly where battery sits
Sry bad eng but i think u get me

Hi, it fits fine. It is very slightly raised on battery side by a tiny unnoticeable amount so I wouldn't say it is flush but such a small amount it doesn't show, just a fraction of a mm. I will post some photos tomorrow. I did strip out the nfc and wireless charging and took the paper wrap off the battery and removed all adhesive from under the battery to save as much space as possible. It was worth it though.

Do you think the case would hide this?

Nice mod man, but aint out there, aftermarket batteries with higher capacity than the stock ones?

I'd be very suspicious of aftermarket batteries claiming extended battery life as there are nearly always fake. However, the S7e battery is 3600mah compared to the s6 2550mah and patona is a well respected manufacturer. It certainly seems to be good quality judging by the battery life I've been getting from it.

Definitely as it is barely noticeable anyway.
Photos below show the back. As you can see it is totally flush with the top and bottom and it is raised by a fraction of a mm on the battery side but it is so miniscule you would never notice unless you look really closely. There is no gap but just doesn't sit quite as flush as standard but to the untrained eye you couldn't even tell.

I removed the Nfc and wireless charging pad to free up a little more space and it fits nearly perfectly. There is a miniscule raise but it's a fraction of a mm and you would not notice it unless you look really hard.
A few weeks down the line I'm still getting amazing battery life. This was the last charge cycle I did and I got over a day and still had over 40% charge left
Search for Patona s7 edge battery. I think I got mine off amazon but can't be sure. They are a German company I believe.

Nfc is not needed but wireless charger. [emoji848]

I am thinking to change the battery with an s7e one because after school 6:40-1:30 I have only 30-50% battery heavy usage to normal
can you share a link where I can buy this battery ?....thanks!

No, because the s7 edge and s7 have the connector on the other side of the battery. I am not aware of anyone finding a battery to swap for the s6 edge I'm afraid.

S6 active battety can fit s6 edge i heard. But i can't find battery for s6 active to try.

I wanna ask how the phone recognise the new battery because there is huge differences between batteries? Did you use custom rom or kernel and did you do something special so the phone to show correct percentage ?

I have buy a chinese battery and i plan to change it these days . One russian guy claims that it fit perfectly in the phone. My question is did you do someting special that the phone to rocognise the correct capacity of the new battery? Are you using custom rom or kernel? Sorry for bad english!

Hi, i'm using a custom s8+ rom with a custom kiboi kernel which recognises the 3600 mah battery.

Official S20+ Exynos Battery Life Thread

Post your Battery usage here. Lets see what we get with these new devices.

Is Bad battery...

Can't say I'm very impressed so far, I switched from a snapdragon s10 plus. Stand by battery drain was never a problem on the s10. I would finish the day with at least 50% battery left. Less than 3 hours screen time and I'm at 40%. And that's running at 60 fps, 1080p. Snapdragon was so much more efficient for me.

So far, not too impressed either, getting 5.5 hours of screen on time, with no video watching or gaming. Literally bit of instagram, whatsapp, messenger, camera and spotify. This is at 120hz FHD+.
This will honestly be my my ''normal usage'' but still having removed it from charge at 9.30am and after 12 hours on 20% is a bit sad to some point, specially after those youtube videos with 6.5 hours of screen on time playing games and and filming videos and what not... Hopefully they will get a fix for it, this is UK version with the (not so lovely) Exynos...
Coming from an LG G6 lets say battery wise Im having same performance

For me 6 hours with 120hz, that literally destroys the battery, switching back to 60hz you get 1 - 2 hours more....watching youtube is no issue, but as soon as you get to any scrolling or
multitasking it all goes away.. especially with that 120hz, also it's not very efficient in standby, you can go to sleep with 100 percent and wake up with 93 or something like that..
Hopefully they'll get an update

Not awesome battery life, if I wasn't careful I need to charge twice a day

50% left, 2h33 min screen on. I disconnected charger at 12am, woke up at 7am. Lost 5% during the night with 4g on. I was playing a lot today. Screen at 120hz

It's so unbelievable bad... Damn :/

I'm glad i.ordered the Snapdragon version

This is always the case when buying Samsung flagships early. An update comes out a few months after to address the issue.

Hmm, I have to agree with you. Upon further use, I don't think stand by drain is the issue. It seems to be more app optimisation. Have to give it some time for developers to optimise their apps for this processor.

Don't get me wrong I totally agree with you. There is even speculation that exynos doesn't get the same Sony sensors for the camera. Instead we get Samsung made one's. Totally not cool for sure. I imported a snapdragon s10 last year and it was amazing for battery life profomance. But honestly, I can fully charge this phone in just over an hour. So to say that the shorter battery life is a major problem is just not true imo.

Which country are you from? Did the Snapdragon work perfectly with your carrier and 4G?

I understand, but I haven't come even close to needing to charge the phone during the day yet. I'd say I'm losing about 10 to 15% more battery then I did on the s10 so all good for now.

Yes, "usage pattern". I'm charging twice a day with the +, something that I did years back..

This is the only complaint i have so far, battery life. It is not disturbingly awful, but I usually have to charge it in the late afternoon, so I dont run out of juice in the evening (I am getting 3.5 - 4 hours of screen time). Situation is even less annoying since It charges really fast. I am running optimised battery plan, bluetooth, wifi, data on. Other than that it is a beast, I am fully enjoying android freedom over my iphone X. Battery will probably improve with updates though.

First and first full charge, 120hz all time. Let's see next days.
