Honestly screen on time is very subjective its also heavily dependant on what games you play or your brightness levels.

What is Important is :

- How far does it stay with you while constantly using it?

- Does it last your entire day like from 8 AM until like 10 PM? Then congrats.

Is this Normal SOT? Note 9 EXYNOS SOT drop dramatically after PIE update!

1st photo - Note 9 Exynos 512GB

2nd photo - Note 9 Exynos 128GB (battery life seems abnormal??)

3rd Photo - Both running the same Android PIE firmware.

After updating to Pie, the battery life became really bad. From 9 house SOT to 1-3 hours SOT...

Anyone able to give some advices on what to do? :confused:
[Samsung Galaxy Note 9 Real Life Review] Bigal77:
This is terrible

I never got less than 5.5 SOT. Avg is 6.5, and have gotten 8 over 17 hour days
[Samsung Galaxy Note 9 Real Life Review] cavags5:
Hi mate,

I think you don't need ad guard app, in the 2 could be you have something always syncing, One Ui after upgrading need a reset, and you can optimise all app you don't need notifications.

Phone will learn your usage after a week or two.

Sync and signal could be always a big drain.
[Samsung Galaxy Note 9 Real Life Review] melchiar:
I have never had more than 5 hours SOT, and I'm not even a power user! Is there anywhere a good guide or summary for non root users, that sums up all the steps we can take to have best battery life??? If not, can anyone with the right knowledge please take the time to sum up everything in one post... Me and others will be very gratefull

Note 9 Battery-Abuse

I suggest to run an app called "photorealism benchmark 2018" (it's free on google play)

If anyone can hit this infinite test from 100% > 0% in 7-8hrs i will def buy this device

With 50% screen brightness and continuous run till battery dies out
[Samsung Galaxy Note 9 Real Life Review] melchiar:
I have used this device for 4 months now. Always kept it relatively clean. Didn't have great batterylife like some other users here, so a month ago did a hard reset and kept things even cleaner..

no unused apps

no heavy gaming

not a poweruser

Using WiFi where possible

Using mobile data only when needed

Optimised battery status

Auto brightness

Never gamed more then 15min a day

No fast charging

...

The maximum SOT I got out of this device is 5 hours. I just can't understand how some people get 8hours!? My experience, in real life it isn't like it is advertised and reviewed.

If anyone with 8 hours SOT can make a step by step guide.. me and others will be grateful
[Samsung Galaxy Note 9 Real Life Review] thienthancongtu:
I know with android battery life, im a freak when it comes to it.

You can easily get 8-10 hrs of SOT if you just put like 8 hr duration of a video and play it internally and keep the screen on at around 30% brightness (trust me)

Download any 1080p or 720p and put it in the phone storage and using the built-in video player app

-------------------------------------------------------------------------------------------------------------------------------------------------

I want to know like real heavy use such as running photorealism benchmark 2018

even 4000 mah pack can die within 4-5 hrs :)
[Samsung Galaxy Note 9 Real Life Review] christechno:
amazing contribution thanks for sharing this. :)
[Samsung Galaxy Note 9 Real Life Review] thienthancongtu:
You have SS note 9 right?

Playing infinite GPU benchmark might deplete battery in 4-5 max i guess

playing 1080p or watching youtube vids can take up to like 8-9hrs? SOT?
[Samsung Galaxy Note 9 Real Life Review] avolitez:
İ simply cannot take it anymore. its been amazing at the start with 5.5 hours of sot and now this is my biggest issue.

I cannot even make it out 2.5 hours now. nothing changed in my usage. charged it regularly not harming it. my phone is 7 months old.

Any suggestions to make my phone back to life again?

[Samsung Galaxy Note 9 Real Life Review] danielsinnema:
Poor battery performance

A year ago I was doubting whether to choose the note 9 over the note 8. I ended up buying the Note 9 for one main reason: the battery.

I see many people praising the battery life of the Note 9. Unfortunately, I'm still pretty unhappy with the battery performance. I can't get through the day. The battery has almost completely drained after a 9 to 5 working shift, without having touched the phone too many times.

Do you guys have tips and tricks on how to optimize battery life?

I have a custom dpi, highest resolution, customized keyboard, Bluetooth headset, multiple news app, not too many games, app locker, social media apps, music apps, animated wallpaper on lock screen, Tasker sending automated email every 10 min. and a ton of apps. Still, I wouldn't call myself a "heavy user" .In "device care" I don't find any app draining the battery in particular.

Which of the previously mentioned items drain the battery the most?

This is a screenshot of battery usage:

[Samsung Galaxy Note 9 Real Life Review] justmoto92:
Before the Android PIE update, I typically gets around 6-10 hours of screen on time. :(

Now both of my Note 9 (128GB and 512GB model) gets around 2.5 to 4 hours of screen on time.

So the idle time is not the main issue here.
[Samsung Galaxy Note 9 Real Life Review] cavags5:
Can you send a screenshot of the battery of the apps are draining.

What email app do you use?

Do you have sync on all the time,?

Do you use 4G WiFi, is the signal good?

[Samsung Galaxy Note 9 Real Life Review] thienthancongtu:
Only Playing 3D games/Running 3d Graphic counts

IMO, browsing/utubing/surfing websites/SOT playing local videos (offline mode) do not kill the battery

More accurate SOT would be

Grinding levels in MMORPG/RPG games in Continuous hours

Running 3D graphic apps in hours

Playing 3D games in hours
[Samsung Galaxy Note 9 Real Life Review] ToRRIIDeR:
Normally i get about 6-7 hours SOT with optimised mode, and that is with 8hrs of 4G, lots of social media, GPS usage, AOD. However i wanted to see how much more battery I would get by turning on power saver mode. It actually impacts alot. I still get my 2 emails synced, but the battery improvement is very significant, about 30% better. Its become a battery champ. However apps do close faster, its a bit more sluggish, but otherwise very impressive results
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
That's really good. You are getting approx 4 to 5 hours per 40 or percent of battery.
[Samsung Galaxy Note 9 Real Life Review] ahmedcool166:
This is my note 9 battery usage:

1- phone is only two days old (This is the second charge cycle only)

2- AOD is always on.

3- WIFI nearly always on.

4- GPS/Bluetooth/NFC/Face Unlock - All is always on

5- Using One Sim with VOLTE Always on.

6- Using Dark mode.

Hello everyone, I'm from France and I discovered this forum.

I have a question about the Galaxy Note 9 because I want to buy it when the Note 10 will release.

Is the battery good ?

I want to buy this phone because everyone say that the battery is perfect but I read the pevious posts and it seems like the battery isn't good since the last update.

Can you help me ?

I want a phone which can be usable for 3 years minimum
[Samsung Galaxy Note 9 Real Life Review] michelino159:
Note9 has a better autonomy on Oreo than it now has on Pie.It is a good phone and keeps you battery all day now depends on whether you are a power user then maybe you will need a new recharge. Exynos processor 9810 is not brilliant in standby and especially if you use two sims. It will have a future update to android Q and patch security until 2021. I say it's a good business if you want a Note phone.
[Samsung Galaxy Note 9 Real Life Review] Fawora:
Thank you, I will be waiting, the battery can't be more bad than Galaxy s8, i have this one actually
[Samsung Galaxy Note 9 Real Life Review] michelino159:
You can buy Notes 9 on the snapdragon which is a bit better than exynos, with a better video card, a better standby, but it does not benefit from Samsung guarantee in Europe only in the USA and China. But many do not need warranty, but must to be lucky. :)
[Samsung Galaxy Note 9 Real Life Review] Fawora:
Yes but I prefer an european version because like you said, it's better fir the guarantee.
[Samsung Galaxy Note 9 Real Life Review] michelino159:

[Samsung Galaxy Note 9 Real Life Review] thienthancongtu:
To be honest my friend. They could have left the screen on for just extreme light tasks such as watching youtube, or playing videos locally

This can last them about 8~10 hours easily.

If you are serious about the REAL-LIFE SOT with REAL - LIFE HEAVY EXPERIENCE we should test this phone with heavy applications such as

1: 3D loop benchmark

2: 3D Gameplays

3: All features are on + GPS + Gameplay

this phone can last about 4-5 hrs of SOT with those options turned on i believe

i've been doing lots of research about phone batteries... this is spoken from my own experience only
[Samsung Galaxy Note 9 Real Life Review] ihuman007:
If u want a good battery and fast phone go for p30 pro. If u want the note 9 specific features buy this. Battery is decent, but not the best

Are you aware of what is Huawei going through ? Not a great advice atleast for now, buddy.

Only Playing 3D games/Running 3d Graphic counts

Very cool information but

IMO the best SOT test would be everything is set to default and run 3D app from 100% to battery depletion

To stress the device to its maximum power

I doubt if this device can last 4-5 hrs straight from 100% - 0%

(for example if you run 3D app and let the screen on 100% at all times plus LTE on + everything on by Default)
[Samsung Galaxy Note 9 Real Life Review] Jovan1997:
Here is my, 6hrs watching GOT on HBO app, 2hrs fb,insta, chrome....25%left

[Samsung Galaxy Note 9 Real Life Review] ihuman007:
How is it so good for u.
[Samsung Galaxy Note 9 Real Life Review] uchihakurtz:
I found that turning off this settings improves the battery life by quite a lot. Maybe you can check if this is turned off or not.

I dont know, battery is old 8months... 6.5-7hrs SOT after last update

Dark mode and wqhd+ resolution...I ll be try power saving

Ps: Just checked, last update bring very good SOT, posted screenshot before update
[Samsung Galaxy Note 9 Real Life Review] Jovan1997:
3days without charging? Omg ?
[Samsung Galaxy Note 9 Real Life Review] melchiar:
I'm using this phone 5 months now. Never had the battery life as advertised or how some people here are getting, hard to believe it's true. This is NOT a beast in my opinion. Screenshot is taken when only 15% is left.

Not a power user

Power mode Optimized

Screen resolution FHD+

Auto brightness ON

No gaming

Now and then Facebook lite, Netflix, YouTube, WhatsApp, Chrome

Very little Mobile Data (max half hour a day)

About 12 hours WiFi

Bluetooth is standard off (max half hour a day)

NFC OFF

No high accuracy scanning BT or WiFi

AOD only on tap

Location ON

As you can see not a power user. I've done reinstalls and resets (soft and hard), never had more SOT then 5 hours with moderate usage. I understand a lot of people are happy with this phone, but for me, as it is my first Samsung, I'm not that impressed other then the SPen and it's capabilities..

Is there something I can do to improve battery life?
[Samsung Galaxy Note 9 Real Life Review] Synt4x.93:
On oneui I only get 6/7hours SOT, but with los15.1 I get 10 hours.
[Samsung Galaxy Note 9 Real Life Review] jult:
Switch off Location. GPS has always been a drainer. Switch off Samsung Cloud app.

But even then, I have similar use without Location ON, and also not very happy with battery life of the Note 9. The worst of all smartphones I've ever owned. It's at 15% around 20:00 every day.

I'm experimenting with tuning The Galaxy Project kernel in favor of battery life, and this does seem to work somewhat, but it's in use too short to make solid statements about that yet.
[Samsung Galaxy Note 9 Real Life Review] melchiar:
Is that the best ROM for Note 9? I have the Exynos model. Is it stable? Any regrets? Did you lose any important stock features?

Can I see ho much battery the Location Service consumes? I don't use Samsung Cloud for anything..
[Samsung Galaxy Note 9 Real Life Review] Synt4x.93:
Location doesnt use that much imo. I leave nfc and high accuracy gps on all day.

[Samsung Galaxy Note 9 Real Life Review] Reno95:
Exynos here. Has anyone noticed that limiting CPU speed (power mode) doesn't have any effect for better battery life? Before Pie, it was working. But after updating, it doesn't save me any extra juice anymore. Been using Pie for 5 months now.
[Samsung Galaxy Note 9 Real Life Review] melchiar:
Yeah I think so too.

Thanks but tbh I don't want to root and fiddle with ROMs. Especially not with unofficial that has nonworking items.. thanks anyway for your effort in making and maintaining that guide.
[Samsung Galaxy Note 9 Real Life Review] Paninno12:
Exynos, with aod, wqhd.

Battery is better than on Oreo.
[Samsung Galaxy Note 9 Real Life Review] michelino159:
It's a good battery because you do not use the phone. I charge it twice a day with Pie and when it was Oreo, once.
[Samsung Galaxy Note 9 Real Life Review] Paninno12:
What do you mean by not using the phone ?

3 hours of SOT in 2 days is plenty of usage for a lot of people.

If you use your phone excessively then it's a different battery life experience.
[Samsung Galaxy Note 9 Real Life Review] Exynosthrowaway:
Is there any tutorial around here to help me do this? I have the europe exynos
[Samsung Galaxy Note 9 Real Life Review] Synt4x.93:
Wow, this is awful.

Has it always been that bad for you?
[Samsung Galaxy Note 9 Real Life Review] Paninno12:
Unfortunately, yes. But considering the 2 days usage I'm kind of ok with it.

I'll try to push the battery for a 12 hours day, see if I get better SOT...

Sometimes I feel like I want sell my Note 9 for a Oneplus 7 or 7 Pro, which gets much better SOT and stand by time.

Did anyone made the switch ? How's the camera on the Oneplus 7 compared to the Note 9 ?
[Samsung Galaxy Note 9 Real Life Review] Exynosthrowaway:
Thank you! So basically i can get rid of anything, even that damned facebook that i can only disable?
[Samsung Galaxy Note 9 Real Life Review] Synt4x.93:
For 2 days uptime that is awful, this is what i get with los15.1 with AOD enabled.
[Samsung Galaxy Note 9 Real Life Review] Synt4x.93:
Exactly ;)
[Samsung Galaxy Note 9 Real Life Review] Paninno12:
That's really tempting. Can you use Samsung Notes on Lineage? how's the camera ?
[Samsung Galaxy Note 9 Real Life Review] Exynosthrowaway:
i uninstalled a lot of the crap, including everything facebook related.

the only thing i forgot is that i still need the facebook messenger app for univ from time to time, and now if i install it from store, i open the app and it gives me the error inside messenger that something went wrong. what's the apk that i need to download for this to work again? facebook.com.orca?

does smartthings do anything for the note 9, as in it helps with the spen connectivity ? think this might be the last one i can get rid of

i'm new to all this power user stuff, i'm glad i found out about all this so that i can make my phone smoother
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
Also looks like no phone radio was used or disabled.?
[Samsung Galaxy Note 9 Real Life Review] melchiar:
So today I went to the Samsung Service Center again. I explained that I'm not getting the battery life that is expected with my usage (see in above post and screenshots). They hooked it on their computer and ran a scan. Couple of things came out, an app force closed 2 times some time ago, and the stock Samsung Calendar app used between 5 and 10% battery overnight on couple of days. But other than that no weird things. He said it's not normal behaviour of the Calendar app, and I was like "That's the stock app, shouldn't that be the "lightest" sollution?". He suggested me to put all apps in sleeping apps list, except the ones that need Push notifications and such. Weird sollution as I'm not a heavy user. Anyhow I've done that and I'll see what it does..

Question to people who know what they are taking about when it comes to this phones battery life: If you take the info from my post in quotes above about my usage, and the screenshots (last screenshot is taken at 16%), Is this or is this not the battery life I should expect. Please a logic and reasonable answer.. thx

(No I don't want to fiddle around flashing ROMs and Kernels)
[Samsung Galaxy Note 9 Real Life Review] melchiar:
I'm not on LTE most of the time. As I stated in the quoted post you can find in the post you answered, I only use LTE when needed and that's about 30 to 45min max a day. Bluetooth also when needed, max half hour a day.

Besides that, I have disabled all bloat apps that could be disabled that I don't need. Facebook, LinkedIn, Microsoft Office apps, T-MobileApp starter, ...
[Samsung Galaxy Note 9 Real Life Review] melchiar:
Thx for taking the time. I think I'm gonna do all the things you said here. But if I may just a couple of questions just to be sure.

1. This is the thread you mean? "https://xdaforums.com/galaxy-note-9/how-to/official-stock-fw-update-odin-thread-xx-t3825204"

2. My CSC is ODX, I cannot find it in the list they provide in that thread. That's means I cannot use this? If I remember correctly it wasn't ODX at first, it was MAX, Austrian T-Mobile version. Don't know how it got changed.

3. I know flashing and rooting makes you lose warranty. But does this to?

4. Will I get OTA's?

Thx

Battery wear

So I've been checking my battery wear level by using AccuBattery and Samsung Phone Info app for a few days now and it shows that It's already on 89% and 87% respectively.

It's not even a year old and interestingly with AccuBattery It decreased by 4% (from 93 to 89%) since I started using the app two weeks ago even though I followed the tips to charge before it reach 20% and unplug the charger on 80-85%.

Is it normal? :confused:
[Samsung Galaxy Note 9 Real Life Review] michelino159:
Do not worry. The two applications do not record and do not show the correct number of charged mAh or battery health. I use the Aida64 application and the Battery section you have Charge Counter. My Note9 has almost 1 year and I charge it 100% and every time it shows me 3753mAh.
