yes exactly i am using same like you my device no gaming nothing only using web based apps ( i done all optimisation etc and no deblot in my phone all disabled completely by package disabler pro and my non usage system apps disabled but still no use)

i think Samsung is not efficient in web based optimisation apps

---------- Post added at 04:59 PM ---------- Previous post was at 04:50 PM ----------

i done all my best optimisation but no use on web based apps, Samsung is not efficient, i need to personally tweak the kernel to get optimised its conman in exynos variant the same issue is there in s9+

Tip

Hi I had this problem, initially, try factory reset and dont restore apps/settings from backup. Install apps individually. I get 5hrs of SOT now.
[Samsung Galaxy Note 9 Real Life Review] Zanders18:
Exynos version. Charged to 100 on day 1 but didn't use it with a sim so purely wifi as I needed to do some backups from my 3T. Was about 40 hours with 7 hours screen on. Did another cycle from 0-100 then put my sim in today at 100. About 5 hours on 4g the rest on wifi, currently at 31% with 6 hours screen on time, 13 hours or so off charge. Turned off AOD and using Samsung dark theme and dark Twitter & Samsung browser. Will try to keep it at 85% max going forward but anyone who is still on the fence I would recommend this phone more than any device I've experienced so far. It is awesome
[Samsung Galaxy Note 9 Real Life Review] leoking3:
Check this out, it really took me by surprise :)). Exynos, 4g combined with wifi, some online radio, email set to sync, autobrightness, Bixby deactivated with Package Disabler Pro, whatsapp, fb Lite and Fb Mess Lite, no Instagram, a few calls, videos about 1 and a half hours.

Odd, but a good odd :))

My second day of using the note 9, no amoled themes, optimization. Got my screen at QHD, location on, sync on, LTE on for half the duration of my day and wifi the other half. Played 2 full games of pubg on max settings (45 mins). Lots of instagram, Facebook, YouTube, and chrome. Started my day at 1130am, ended at 1:15am. Got the 6gb Snapdragon version.
[Samsung Galaxy Note 9 Real Life Review] fritzen:
Hello, this is my SoT. Exynos, 6/128, 80% in LTE, dual.sim.
[Samsung Galaxy Note 9 Real Life Review] vojopd:
90% of the time i Get 6+ sot on note 8, gaming, youtube, social networks, 80% wifi... So they aren't fake. Most of those people don't use games. It is always a + if you have a excellent network signal, whenever it varies, i get very bad battery life.
[Samsung Galaxy Note 9 Real Life Review] @rbiter:
I think you're just upset you are not able to get these SOT. Fake would be when I accidentally left my screen on note3 overnight on a blacked out theme and somehow it stuck on a 100% black page and I had 24h SOT with plenty of charge left. But I posted what happened. And as mentioned signal strength helps a lot. LTE is more efficient than WIFI now if you have a strong signal. There is no way in the world I could my SOT on AT&T because their LTE is lousy and their speeds abysmal. AT&Ts LTE is like HSPA in latency and speed.
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
Or they have it on power save mode for half the day then switch back to power save mode off before taking screen shots. Personally, I've never used power save mode nor did I on my note 8.
[Samsung Galaxy Note 9 Real Life Review] fulcrum1971:
The best I have got so far. Average screen on time is 4-5 hrs with 20 hrs of usage
[Samsung Galaxy Note 9 Real Life Review] RichardC27:
First time I've gone almost all day off the charger since getting the phone on Friday. Mostly on WiFi, have Facebook, Instagram, Facebook messenger all installed and used throughout the day. Over an hour of YouTube, downloaded a few apps, loads of messing around trying to get my home screen how I liked it. The small charge on the middle of the graph is me driving home from work using Android Auto for navigation and music so I have to be plugged in.

No special optimisation, screen running at full resolution and auto brightness on all day.
[Samsung Galaxy Note 9 Real Life Review] Priwiko:
Very happy. 90% wifi. Only games.

Exynos.

no idea how to give screnshot :(
[Samsung Galaxy Note 9 Real Life Review] adelistiawan:
WQHD+, Setting on screenshot, 90% 4G+ because outdoors usage. no optimisation, playing games asphalt 9 arround 20 minutes. A lot social media like twitter, facebook, instagram, whatsapp, line, messenger(group call). Exynos 6gb version
[Samsung Galaxy Note 9 Real Life Review] ShadowFlare:
It's all about how you use your phone and what things you use on it. Don't just complain you have short SOT, lay out all the things you do, what you install, what you have running in the background, what Push/Sync stuff are running, share screenshots, etc.

I'm on Exynos 8GB, screenshots are from my 7th day using it, it was at the end of my day and was going to sleep. On days I play Pokemon a lot WHILE watching Youtube, SOT would be around 4 hrs and battery would be under 30%, the screenshot is on the day I played just a little.

My previous device was S7 Edge 128GB, I would have to top up my battery midway throughout the day when I play Pokemon on my way to work. With Note 9, so far I never had to, and always have plenty of juice at bed time. I love this thing. Although, hearing Snapdragon 845 models are a lot more efficient than Exynos 9810 models bothers me a little.

Edit: Resolution was at FHD+, gonna try QHD+ from here on. Brightness always on Auto. 4G/LTE, WiFi On all the time, Bluetooth connected to Gear S3 throughout the day and to Sony WI-1000X on my way to work and home (roughly total to 3 hours).
[Samsung Galaxy Note 9 Real Life Review] mickeyleah:
I get very good battery life, i usually take it off the charger at 6:30 am and yesterday put it on the charger at 11pm with almost 40% left. Today was heavier usage but more well rounded with internet, youtube, music and gps.
[Samsung Galaxy Note 9 Real Life Review] @rbiter:
Various rundowns the last 2 weeks. Been fairly consistent too. I get a little worse when I use it in the sun more. I haven't let my battery tun down to single digits yet. I might try to shoot for 12h video one day while battery is still super fresh.

I have not used any power saving, full resolution, mostly with Bluetooth connected all day except the first screenshot which was today and I forgot my earpiece. My notifications were black in the pull down by for some reason they reverted to white again. Qualcomm pulled off another Snapdragon 805 but only better. I think the hexagon 685 DSP which the Exynos does not have is probably more helpful than people thinking it is the CPU. Samsung has had plenty of time to get their scaling right on the CPUs. I think the DSP chip is used more than ever. I wish Qualcomm and Samsung would release more specific information. Need Anand Shimpi and Brian Klug back at Anandtech. I can't believe they sold out t Apple. Anandtech was he bomb breaking down components on SOCs.
[Samsung Galaxy Note 9 Real Life Review] Amit.A:
i have very limited apps (in total my apps are in 1 page of touchwiz without folder) my most use apps are whats app facebook email and telegram, rest all are used very very rarely, (gear sport connected from 7am to 5pm) and rest of the time it will be in stand by, and sync turned on, not using any dark themes, kept the display to FHD+, AOD turned On, and mobile data turned on and wifi turned off when not in use most is mobile data than wifi, all other no use apps like secure folder knox spay etc etc are been disabled as i dont use them dont use any lock on device,and no gaming at all, so in overall for this usage i should get atleast 5 hrs but not 3hrs of use (this is not complain, this share of problem, as far i felt note 8 is better than my note 9, note 8 gives me 4.5hrs of battery)
[Samsung Galaxy Note 9 Real Life Review] marko94:
You have exynos version or SD?
[Samsung Galaxy Note 9 Real Life Review] @rbiter:
Snappity snap snap.
[Samsung Galaxy Note 9 Real Life Review] Ronny220:
WQHD+ exynos note 9, well Impressed with battery life. See attached image
[Samsung Galaxy Note 9 Real Life Review] michelino159:
It is still said that Snapdragon is better at battery than Exynos but I think it's a minor difference. I easy to take over 10h SOT on exynos those more wifi and if it's only to use mobile data, minimum 7h SOT.Snapdragon has a a very good modem that gives you a very good gsm reception than exynos here and consumption in stand by. Next to it all will report on the article on Anandtech with S9 exynos and snapdragon. It was a differentiation then, but now I see it oriented software. I had Note8 and a little time S9 + but it does not compare to Notes9 which is much over.?
[Samsung Galaxy Note 9 Real Life Review] Virgo_Guy:
More than a week post August OTA update, Exynos 128 gigs.

Measures :

AOD Off, Auto brightness ON , 2 email accounts (one is in sync except for "Google fit data" & "play games cloud save", other is in sync only for emails), No cloud syncing of any photos, video in gallery, location service on high accuracy(wi-fi Scanning and bluetooth Scanning off in "improve accuracy"), button mapper on bixby, dark theme & wallpaper, 19 apps I keep using are kept in "not monitoring" , screen is in WQHD+, find my mobile services are off, in developer mode "mobile data turn on" is OFF, Samsung health service is ON, about 80 % of the time connected to Wi-Fi , full mobile network signals, no game playing at all, edge panel on, edge lighting off, in Advanced Features - smart stay, smart capture, smart alert, video enhancer are on, rest off. FB(set to not eat battery much) insta,twitter, whatsapp installed & used lightly, disabled 8 preinstalled bloatwares.
[Samsung Galaxy Note 9 Real Life Review] IgNite1:
8 hours SOT with 2 days 16 hours standby drain

1.5 hours on Youtube

1.5 hours on Spotify

2 hours watching movie on VLC (its not on the log it disappeared after a while)

The rest of the 3 hours were spent on stuff like Chrome, Discord, WhatsApp etc

Note : I did turn off Always on display because i didn't want to know what my phone battery was - If i see my % i become too anxious about saving juice

Also, WiFi + Cellular + Bluetooth were turned on for most parts
[Samsung Galaxy Note 9 Real Life Review] michelino159:
Exynos ?
[Samsung Galaxy Note 9 Real Life Review] vojopd:
Hahshahsh yeah, 6h of nothing... Stop lying.
[Samsung Galaxy Note 9 Real Life Review] michelino159:
What lying?Look, I've posted more. There's no lie. Stop envy!:laugh:

Exynos ✌
[Samsung Galaxy Note 9 Real Life Review] vojopd:
Yeah, lying. Maybe reading a book for 6 hours or reading news in samsung internet browser, but playing games, youtube, fb, instagram... nope... Nice try btw :) !
[Samsung Galaxy Note 9 Real Life Review] michelino159:
We do not have the same pattern of use and the same programs but for what I need is excellent. Like with snapdragon, for someone it can be excellent, but for someone else. I wanted to show that on Exynos the battery is pretty good if you know .

Look the screen. ;)

FB,instagram,twinter are in browser. ;)

No game for me.
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
Yep 7 hours sot with 49% juice remaining.View attachment 4592392
[Samsung Galaxy Note 9 Real Life Review] alex989898:
I don't see why you think that. I get roughly the same battery life as him (also with the Exynos model) and I'm not reading a book or only using Samsung Internet Browser.

I use mostly YouTube (2.5h), reddit (1.25h), Samsung Internet Browser (1h), Messenger and another forum app (and, obviously, XDA)

Edit : My wife also has a Galaxy Note 9 (Exynos) but her battery life is not as good as mine I think. It's not a huge difference but it's noticeable.

I don't know if it's a matter of settings/apps (I doubt that, we use almost the same apps and settings) or a lack of quality control (which has never been the strongest ability of Samsung).
[Samsung Galaxy Note 9 Real Life Review] ihaveabu:
My battery has been pretty crappy. Had the phone for 3 days.

Snapdragon, AOD on, QHD+, all radios on, Wifi Scanning on, Bluetooth scanning off, auto brightness, paired with Gear S2.

Solid cell reception in my area. Have not used battery saving mode

9% battery per hour on average with standby is pretty bad.

How are you guys getting 6 hrs+ SoT and still 50%?

Added in Accubattery screenshots from later on today. Seriously 9% per hour drain average with screen on and off time.
[Samsung Galaxy Note 9 Real Life Review] alex989898:
I see 4 things that might be the problem :

First, you have a Snapdragon model, I have an Exynos. On the S9/S9+, the Snapdragon was more battery friendly than the Exynos but there is no clear evidence that's still the case. In fact, I remember seeing a video where the Note 9 Exynos showed a 22% better battery life than the Exynos S9+ despite the fact that he has only 14% more battery.

Secondly, I don't use AOD but I don't think that's the problem. It barely consume anything.

What's more interesting IMO is that you use YouTube Vanced. I guess it's a Youtube player ?

If it's the case then it's really not optimised as well as the official YouTube cause I use YouTube more than twice as much as you and yet it consume twice less.

And one last thing, I don't have anything paired to my Note 9. This can totally be what's killing your battery life.

For everything else, I do exactly like you (except cell reception which is not incredible in my apartment but I use phone over Wifi when at home).

Attached, you will find my battery log (and it's time to charge my phone I think)
[Samsung Galaxy Note 9 Real Life Review] hackdrag0n:
My Exynos model seems to be doing ok. Not the best battery life I've ever seen but it is one of the better phones I've owned in this regard. Hoping it will get a little better with updates too.

Your usage is definitely really high. If I had to guess I'd say an app on your phone is causing issues, but it's just a guess. Sometimes high android system usage can actually be from some other app causing android system to keep the phone awake. I'm not really an expert on these things though.

View attachment 4592683
[Samsung Galaxy Note 9 Real Life Review] ihaveabu:
Yea if my usage above is considered heavy use, then I can see how everyone's battery life is better. I have a lot of apps that I use on a daily basis. Accubattery's app usage section was 5 screenshots long.

Hopefully it settles down but most of my screen on time is with YouTube and messaging. YouTube Vanced should be exactly the same as YouTube. I use the full dark theme too so it should be using less battery. I do stream my videos at full HD or 1440p when on wifi though.

Will post another set of battery usage for today and compare.

Are you guys running your phones with the mid level battery saving turned on? Or HD instead of QHD?
[Samsung Galaxy Note 9 Real Life Review] alex989898:
I still haven't look at what Youtube Vance is but from what you said I get it's just a modified version of YouTube.

If it's the case then either Accubattery reports are wrong or your device has a problem. At least, it's what I would guess.

835mAh for 1.5h of YouTube is insane !!!

And I tried the power saving mode for a day but the results weren't good enough to justify the loss in fluidity I experienced. So no power saving mode for me.

And of course I use QHD resolution (tried FHD+ on note8 and I couldn't see any gain in terms of battery life).
[Samsung Galaxy Note 9 Real Life Review] ihaveabu:
That is definitely concerning. I'll keep an eye on battery consumption while watching YouTube today. Will post a screenshot of the real time battery usage in a sec.
[Samsung Galaxy Note 9 Real Life Review] ihaveabu:
Here's Accubatterys "real time" usage while streaming a 1080p 60fps video. I notice GSAM usually reports higher real time usage but it doesn't update as often.

This is with auto screen brightness down to around 10% though as I'm indoors in a dim room.

300-400 ma/h doesn't seem out of the ordinary I don't think.

Imgur link if the attachment didn't work

https://imgur.com/a/iGA4eu6

Also overnight standby has been around 1.5% per hour drain which is actually really consistent with what I've gotten with all my phones in the last year (oneplus 5 and 6, essential, note 8).
[Samsung Galaxy Note 9 Real Life Review] alex989898:
Yes, 320mAh seems normal to me (which mean you can watch YouTube for around 12.5h if you do nothing else). But that would lead to 480mAh for 1.5h of use, not 835mAh.
[Samsung Galaxy Note 9 Real Life Review] alex989898:
Ok, I installed Accubattery to do the same as you and see what's going on.

Couldn't use 1080p 60fps on the official YouTube App so I find a trailer of Tomb Raider in 4k and played it in 1440p (I assume it would do the trick because 1080p 60fps is twice the bandwith of 1080p 30fps as should be 1440p 30fps).

And the surprise is that my consumption is way less than yours.

Edit : I see that my screenshot is not taken at the most representative moment. In fact power was a little bit higher on average, around 250mAh, the maximum I get was around 280mAh.
[Samsung Galaxy Note 9 Real Life Review] ihaveabu:
I restarted the phone this morning before taking it off the charger. So far it's looking quite a bit better. 25% auto brightness a video playing while I'm typing this and I'm getting around 250mah and about 7.5% per hour drain.

I did notice in cpuz the cpu wasn't idling at the lowest clock speed of 748/825 mhz before the restart. It was around 1100/1300mhz. But clearing all open apps through Device Maintenance didn't help at all. So it probably affected the earlier 300+mah drain. But all the yesterday I kept an eye on cpu idle and it definitely ramped down to lowest just fine.
[Samsung Galaxy Note 9 Real Life Review] alex989898:
That's way better.

I'm interested to know how it end.
[Samsung Galaxy Note 9 Real Life Review] ihaveabu:
Will keep you posted. So far it's gotten a bit worse. 20 minute drive to work with screen off and spotify streaming off LTE playing to my car via bluetooth.

Cpu idling seems to be fine at the lowest 748/825

I'm up to 13% drain with screen on and 4% screen off. Back to around 7-8% average drain per hour :crying:
[Samsung Galaxy Note 9 Real Life Review] ihaveabu:
Watching YouTube right now and it's actually not much more drain than this morning. 250-350mah. While typing this post it's around 500-600mah though.

My 4G reception is weak so used 3G all the time, Wifi and BT on most of the time. Auto brightness on.
[Samsung Galaxy Note 9 Real Life Review] rebel377:
You guys do nothing power hungry like games and social media with sub 50% and a dark theme

And happy to report 6+ sot? With 50 % battery left? Common sammy fans you can do better

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Samsung Galaxy Note 9's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.

I am seeing a 7-8% battery drain on my Exynos Note 9 :(

I am using

4G data,

no wifi,

no BT,

no NFC,

AOD - On,

All sensors like - Smart Stay, Smart Capture, Smart Alert, Easy Mute etc Off

Screen Auto Brightness Off

Screen at 40% brightness
[Samsung Galaxy Note 9 Real Life Review] chetly968:
I go down about 2-3% overnight. Everything on except for NFC. Had the phone about a week now.

[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
Try turning off all radios ( airplane mode ) when going to bed and see how much discharge you get once you wake up in the morning.
[Samsung Galaxy Note 9 Real Life Review] gCloud:
Is yours snapdragon or exynos?
[Samsung Galaxy Note 9 Real Life Review] liv2drive:
sure i will do that tonight. But even during the day, i woke up at 7AM with 75% and now at 12:20PM it is 34%. I would have been in 30 mins of call, checked mails and whatsapp messages and that's all. NO games, NO video (youtube) etc. Isn't that too much? I am on 4G and all other radios off.

Anyone ever tried analyzing the difference in battery drain between WQHD vs Full HD?

Read somewhere that there is no difference given that the phone still needs to push the same amount of pixels it was built to do. Curious..

[Samsung Galaxy Note 9 Real Life Review] destz0r:
Excuse me?
[Samsung Galaxy Note 9 Real Life Review] Majed aka Soul Guy:
Not necessarily. Could also mean that the signal from your telco company is not as strong as the other person's. This means your phone is pushing more power trying to get a better signal.
[Samsung Galaxy Note 9 Real Life Review] liv2drive:
That's true. My house has bad telco network. Wi-fi does improve the battery drain a lot. Also my N9 is coming out to show its colors. Finished 2 work days with 40%+ battery.
[Samsung Galaxy Note 9 Real Life Review] shawn326@gmail.com:
So far,with Airplane mode 2% and without 3%. No AOD. Also rocks 2.5 days before recharging. At 2.5 days I have 15% battery left. I am impressed but it is still early.
[Samsung Galaxy Note 9 Real Life Review] vojopd:
Hahaaaaahahahahaah 2.5 days... GTFO !
[Samsung Galaxy Note 9 Real Life Review] marko94:
This
[Samsung Galaxy Note 9 Real Life Review] @rbiter:
2% an hour? How the hell do you get 2.5 days off a charge if you're draining 2% an hour? My standby averages .3-.7h an hour. Usually closer to .7%. I wish it stuck closer to .3% because I think .7% an hour is too high for the great reception I get.
[Samsung Galaxy Note 9 Real Life Review] shawn326@gmail.com:
I should have been clear. Overnight I lose 2-3% battery whether I have the Airplane mode on or off. And I find I am charging the phone every 2.5 days.
[Samsung Galaxy Note 9 Real Life Review] @rbiter:
Oh ok. I am losing 2-3% over 7-8h sleep. I'm sure if I had super busy days at work I could go 2-5 days if needed.
[Samsung Galaxy Note 9 Real Life Review] Gerstark:
3% drained with airplane mode and battery saver, 6.5h of sleep
[Samsung Galaxy Note 9 Real Life Review] illetyus:
I have exynos and i have the same issue. AOD, BLUETOOTH open, drains about 1 percent an hour.

Last weekend I was away from my charger so I used the opportunity to keep an eye on the battery.

After 44 hours off charge I was down to 40% with 2 hours SOT. I turned BT off and made sure I had the phone face down so AOD would be off while not in use. Everything else was on.

I think that's pretty good... Exynos chip.
