Coming from a mate 9 I was pretty skeptical about the smaller battery. I can make it through a day, which is all that matters to me.

Best I've gotten so far is 18 hours and a hair under 7 hours SOT.

That was with disabling bluetooth and wifi when not using them.

I generally leave them on as I use them everyday and most days I am at 16 hours and over 6 SOT.

It's definitely not my Mate 9 as I got those hours and had 35-40% left when going to bed. It don't matter as long as it gets me there.

Also considering the battery is smaller on the note 8 and this killer screen.
[Samsung Galaxy Note 8 Guides, News, & Discussion] butchieboy:
Have you tried going to Settings\Location\ImproveAccuracy\ turn off wifi and bluetooth scanning.

It may help I keep mine off.

You can also try Hybernate manager. Even if you lets say leave bluetooth on and sync, once screen is off it puts them into hybernation until you wake the screen. It also lets you select which apps you want to hybernate once screen times out. No ill effects on device. I leave wifi on while im home, as soon as screen is off it hybernates it. When I wake screen it takes about 2seconds then wifi icon pops up...give it a try.
[Samsung Galaxy Note 8 Guides, News, & Discussion] butchieboy:
Just an example of what I have set to hybernate.
[Samsung Galaxy Note 8 Guides, News, & Discussion] JesseMT4G:
Is that OS app? Or an app through playstore? My Mate 9did that and was super helpful in battery life, just have to reload each app everytime.

Also how's come I can't post screenshot anymore?
[Samsung Galaxy Note 8 Guides, News, & Discussion] butchieboy:
Its through play store but to hybernate CPU you need to be rooted. You dont have to go app by app. Everything you use wakes when you wake screen..hybernates as soon as its off. If you want to post screen shots use the actual XDA app post there it will show up here.
[Samsung Galaxy Note 8 Guides, News, & Discussion] butchieboy:
Just keep the ones selected that you want to hybernate, no need to do anything else.
[Samsung Galaxy Note 8 Guides, News, & Discussion] butchieboy:
I also believe that a black background helps..some dnt think so but I think it does a lil...lol every lil bit helps.
[Samsung Galaxy Note 8 Guides, News, & Discussion] JesseMT4G:
Good info, thanks!
[Samsung Galaxy Note 8 Guides, News, & Discussion] Gizmoe:
Here are my pics. I leave everything on I want. Only thing I toggle off when not in use is Bluetooth. Screen brightness is slightly below 50 and auto bright off. AOD on but lock screen notifications off. Also I have WQHD on. I have no apps disabled but i also dont sync redundantly. If i use samsung mail, i only sync that app and shut gmail sync off etc. Made it through a full day no problem and have been using the phone over a week now. I could have hit 8 + hrs screen time no problem before I charged it. Best battery life I have had. Hopefully it stays good for at least a year. My 6P was good only for the first few months. Then one of the updates ruined it. Same with the Pixel XL.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Alex---1:
Not used mine much over the last few days but still amazed at the battery life of this phone.

No power saving on, no 'all black' wallpapers, Wi-Fi on constantly and location some of the tiime. Disabled AOD as my god that sucks battery.

Battery life on My AT&T Note 8 running on Oreo is pretty solid!
[Samsung Galaxy Note 8 Guides, News, & Discussion] bassgenerator:
second cycle. latest firmware.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Mr. Orange 645:
Wow. That's crazy! I get about half that with Oreo on my T-Mobile firmware. But I've never been one those guys to get crazy battery life. I can maybe pull 5 to 5.5 hours of SOT.
[Samsung Galaxy Note 8 Guides, News, & Discussion] bassgenerator:
you already use Oreo on your note8?
[Samsung Galaxy Note 8 Guides, News, & Discussion] Mr. Orange 645:
YUP! Have been on Oreo for about a week. It's still a little buggy, but stable enough for a daily driver.
[Samsung Galaxy Note 8 Guides, News, & Discussion] sserye:
How do you get that battery life? My note 8 is SM-N950F and I get at most 5-5.5 SOT. Thanks
[Samsung Galaxy Note 8 Guides, News, & Discussion] vojopd:
Had to crop it, image too large... That is with use of bk disabler i disabled standard apps that i dont use (dex, gear, onedrive, etc). But, as I googled for best options, i ran onto several threads, that using disabler can shorten my battery... So i enabled all, and will check tomorrow, whats the sot...

[Samsung Galaxy Note 8 Guides, News, & Discussion] mikoal:
I've had the phone for a month and with some tweaking, running Greenify, GSAM to monitor, and Tasker.

I am able to get about 1 day of battery life with 6 hours of SOT with about 20-23% battery remaining

So i estimate probably a potential of 7 or 8 hours of SOT

I use it for browsing, hangouts, texting, the odd phone call.

I do have Greenify killing some functions (only a handful of system like bixby (not voice), samsung bloat, messengers you dont use often, software updates) when the screen goes off.

Force doze kicks in immediately when screen is off

Email sync all emails only inbox, sent. (But this is after I've synced all folder emails)

I run the phone on normal mode, no battery saving mode.

I use adblockers DNS66 and youtube with no ad

set most background app when its not used through the phones own sleeping function

I taskered to kill twitch since theres a battery drain bug i noticed with it. If you dont close dont twithc properly it would leave like a media mode on and drain battery.

phone feels like a rooted phone (wihtout having to lose 20%) since i got the customization and no ads i want. Except I cant do image backups

Use light manager to disable some LED notifications. to save battery and also not receive annoying LED lights on some items such as flashing red when low battery, or red light when charging.

I leave sync, and location on all the time, Wifi toggle when at home.

I use blue light filter when i wake up(easier on eyes) for a few minutes

Brightness is about 40% and set to auto bright.

I do have AOD from 12am to 8am and it does drain more battery. For example i drain .2% per hour wihtout it, then .6%/hour with AOD

I dont use this phone for videos much since i have a Note 4 for that. But daily use (my routine) i dont have to sacrifice anything really to obtain 1 day and 6+ hours of SOT.

I would imagine if I streamed twitch it would be a lot less.

I dont think I've limited myself to anything when using the phone i should do a test with a day of twitch stream or youtube viewing.

How to get YouTube with no ads without root? Thanks.
[Samsung Galaxy Note 8 Guides, News, & Discussion] JesseMT4G:
So what I do now is not give an ish about battery life and throw it on my wireless charger in my work van.

Problem solved, lol!
[Samsung Galaxy Note 8 Guides, News, & Discussion] giongto500:
I have had my note 8 for a week. Below is my sot stats. The only issue with mine is that SD 835 doesn't idle so well. The phone drains 2-3% when standby for 5 hours with only wifi on and AOD off. AOD would consume around another 5% during that 5 hours.
[Samsung Galaxy Note 8 Guides, News, & Discussion] JesseMT4G:
You charged it up somewhat during that time. That's not accurate at all.

Since you are a heavy user, you should try One Plus.

Being an average user, My Note 8 lasts a day and am lovin it. But I think the power saver mode helps in times of need of more power. (Just a suggestion)

13 hours? Ahahahah right

13 hours sot on 15 hour battery life haha that's funny
[Samsung Galaxy Note 8 Guides, News, & Discussion] ilia1985:
You prefer something like this? This my personal use. Previous was just a test to see how long the batter can last and how well the kernel maintains low/idle frequencies. I did similar test on op3t and op5 and both got just under 12hrs. I managed to get this by running YouTube for about 8hrs and the rest was on manga app. Both were done on renovate Rom + xceed kernel release build.
[Samsung Galaxy Note 8 Guides, News, & Discussion] kolikadezso:
Lol
[Samsung Galaxy Note 8 Guides, News, & Discussion] sefrcoko:
That's good SOT, but the fact that it's just over half the 13 hour time previously posted shows just how much different usage patterns can affect battery results. Like benchmarks they are useful, but also taken with a grain of salt :). Same phones, same capacity...
[Samsung Galaxy Note 8 Guides, News, & Discussion] Friendlyx355:
Can i ask how you made your settings black? Mine are white, is there a way to change that?
[Samsung Galaxy Note 8 Guides, News, & Discussion] ilia1985:

[Samsung Galaxy Note 8 Guides, News, & Discussion] j_hansen:
I often get a little over 5 hours SoT with more than 50% battery left and I only use my notes in high performance mode so I cant see why a good modified custom rom and kernel shouldn't be able to achieve 13 hours
[Samsung Galaxy Note 8 Guides, News, & Discussion] sefrcoko:
Screenshots? :)
[Samsung Galaxy Note 8 Guides, News, & Discussion] j_hansen:
stick your note in performance mode for a week and see the difference for yourself.

I dont use Bluetooth or location service much though but I do have 4G/lte and wifi on all the time and in general get very good signals which plays a big part I believe.

in Europe, Ireland using Exynos models of the Note 8s, not sure how much that matters though.

I just don't understand why some people get less than 5hours SoT
[Samsung Galaxy Note 8 Guides, News, & Discussion] sefrcoko:
I'm actually using optimized performance mode, which is why I was asking for screenshots :). Anyhow at that point it really just comes down to usage. Same phones, same batteries. Users could u/v and use low brightness from a 100% charge and never let screen timeout... That would max out screen-on time to epic levels, but no one uses their phone that way in everyday life so it wouldn't be meaningful. 6-7 hours seems typical for most, but I agree that less than five hours SOT likely isn't right unless they've been using it over several days on the same charge. Otherwise likely a rogue app.
[Samsung Galaxy Note 8 Guides, News, & Discussion] note3userr:
No 13 hours is not possible with a 3300mah battery. It doesn't matter what signal you get . It's impossible unless u leave your screen on the home screen and don't use the phone. At the end of the day batteries are physical and there is only so much optimization and software can do. Also sot is the most useless battery stat. On light days I get about 4.5 hours sot but my battery lasts over 24 hours on one charge while other days I might get 6.5 hours screen on time but I have to recharge my phone in about 12 hours . As long as you can leave your house in the morning with a full charge and come back home later at night with your phone still running then it's a success.
[Samsung Galaxy Note 8 Guides, News, & Discussion] j_hansen:
try and switch from optimised to high performance mode and run it for a week, 9 out of 10 people I have recommended this to have come back and said it works way better
[Samsung Galaxy Note 8 Guides, News, & Discussion] sefrcoko:
Misses the point made about usage. Without providing usage details SOT isn't meaningful. High performance mode or not, usage still matters for understanding SOT. It's all good.
[Samsung Galaxy Note 8 Guides, News, & Discussion] j_hansen:
I do get that usage is different, don't get me wrong on that, but please try high performance mode for 7 full days and then come back, I cannot give you a technical reason why it works for me, BUT like I said, 9 out of 10 people I have recommended it to have come back with positive response
[Samsung Galaxy Note 8 Guides, News, & Discussion] vojopd:
Gaming was about 3h+ that day... from 100 to 50%, about 4:30, couple times was 5h sot. This was the best sot i got... Usually it is about 6 hours( around 25% lett) It is usually about So you say if I turn high performance, whd+ and 10% more brightness, I will get better battery?!

Wifi on, location high accuracy, screen brightness auto, mobile data on, NFC on, sync on

If you are rooted please install bbs from play store and post screens from Kernel, wakelocks and alarms. From what I can see you get 2.3hr sot with 10hr uptime which means your phone isn't sleeping at all and is draining battery even with screen off.

My Note 8 was upgraded to Oreo yesterday. The battery life seems like it's the same from 7.1.1.

I just used the phone about 10 minutes screen on time and it's down to 89%. It's been on battery for 14 hours and 19 minutes. I have disabled data, WIFI, Battery saver mode on while I'm sleeping. I did the exact same thing on my S8 and it will only drain 2 to 5 percent. Kinda disappointed on the battery for Note8.
[Samsung Galaxy Note 8 Guides, News, & Discussion] Semantics:
Battery life for me has been no better than any android phone. I also refuse to turn every feature of the phone off, disable a ton of apps and put the phone in airplane mode to get the best amount of screen on time. I get about 3 hours of SoT average but the phone lasts the entire day. I'd rather use the phone as intended and not stripped down to show a ton of SoT.
[Samsung Galaxy Note 8 Guides, News, & Discussion] sefrcoko:

I checked FG_ASOC, fg_fullcapnom and fg_cycle and it shows 91, 2885 mAh and 102 cycles.
