Around 4hrs SOT

But with a lot of gaming and web browsing...

All wireless adapters on all day (4g, Bluetooth, wifi)

Smartwatch connected all day

Location power saving

Auto brightness 40 - 60%

FHD+ resolution

I'm thinking about S9+... Because battery lasts longer...

Edit: I'm on last Soldier's ROM with ELS kernel...
[Samsung Galaxy S9  Real Life Review] Rally517:
I average 7/8 hrs sot.

Right now I'm at 13+ hrs up time.

With 2hrs sot and %70 left on battery
[Samsung Galaxy S9  Real Life Review] PeterGagk:
14h
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
I am sure you are kidding ! ? The galaxy note 9's 4000 mAh battery won't give 14h SOT, except if the ultra power saving mode is on (maybe).
[Samsung Galaxy S9  Real Life Review] _phil07_:
Screenresolution is fhd+, auto brightness (but setting it even brighter sometimes manually) and switching between wifi and data. Usually using netflix, youtube, spotify, navigation, browsing and chatting (mostly the battery hungry snapchat).
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
Android system and android OS take too much battery in my S9. Idk why.
[Samsung Galaxy S9  Real Life Review] xdamember143:
4hrs of sot is the best I can get
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
Here's what I get in battery usage after august update.

But the battery drops about 8% in 19 mins of usage, I think that this is a big problem and we need to find a way to fix it.

I don't want to downgrade to the july update. Is there any solutions for this battery drain?

I can't understand how a 700$+ phone's battery can't last for 5 hours of SOT !
[Samsung Galaxy S9  Real Life Review] ok4n93:
Something is wrong with your Android system. Clear cache, deactivate background use of Android systems after reboot and limit the additional use of GPS accuracy and WLan then you should be good.
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
Will clear cache and disable background activity cause any problems? Because the android system is the base, so how can we disable it's activity? I mean will it affect the security or basic functionality of the device? Also, see the screenshot, it says that backround use is 0 minutes, that means that disabling it won't change anything.
[Samsung Galaxy S9  Real Life Review] ok4n93:
Believe me it doesn't do anything wrong and it affects a lot, you will save a few procent of battery only you deactivate it. Nothing will change in your use, notifications and so on.
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
I tried to deactivate it for an hour, no differences, same battery drain. I searched on google for it and many users tried it and also same drain, and someone noticed that it will automatically turn on after sometime.
[Samsung Galaxy S9  Real Life Review] WittePens:
I get less then 2 hours. Just factory resetted my phone even to see if it persists, installed no apps left it complete stock. Think i got a busted battery or something.

At first i got 4 hours of sot when it was brand new. Now i get less then 2.
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
I got my S9 2 months ago, and I still get around 4 hours of SOT. Ok it's good for me, but I think that it's bad compared to my friend's S9 that lasts more than 6 hrs of SOT, idk why.
[Samsung Galaxy S9  Real Life Review] ok4n93:
It is around 25% difference in whole day usage of Android system. Furthermore you can download greenify and naptime to improve standby time, so you will get more sot overall on a daily basis. Accuracy of GPS and WLan to low and block some useless apps. Clear cache and all this should give an improvement
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
After disabling the background activity of android system, and re enabling it, I noticed that it takes now only about 9-10% of battery usage, but I still get around 4.5 hours SOT.
[Samsung Galaxy S9  Real Life Review] ok4n93:
Right now i get with wqhd and 50% brightness 15% drop per hour, so it is not bad for me.
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
I am on FHD+, brightness slightly lower than 50% most of the time, but I have a lot of social media apps and I always use wifi or 4G, only I turn them off when I want to sleep. Do u think that 4-4.5hrs of SOT is good? ?
[Samsung Galaxy S9  Real Life Review] ok4n93:
On which time of using? The whole day or straight use? For whole day it is definitely okay.
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
For a whole day, it lasts me about 20 hours with around 4 hours of SOT.
[Samsung Galaxy S9  Real Life Review] ГАСООП:
I was thinking about getting an s9, but the fact that crappy Xiaomi I own now goes easy 8hrs sot is just not acceptable :/

How many SOT was you able to get before september update?
[Samsung Galaxy S9  Real Life Review] yourmumsbootloader:
I have seen plenty of pictures in the note9 forum with people getting over 10h SOT easily. there are a couple people who are getting 11-12h SOT but 9-10h seems to be most common.
[Samsung Galaxy S9  Real Life Review] Rally517:

Do u use social media apps or things like that?
[Samsung Galaxy S9  Real Life Review] Rally517:
Yup. Fb,ig, Twitter
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
How do you get this very high SOT?
[Samsung Galaxy S9  Real Life Review] bekcicandrej:
Uninstall Samsung health. I noticed that it lags the phone and it's always on.

(Wqhd+, wifi, data on, ~5h sot)
[Samsung Galaxy S9  Real Life Review] Rally517:
Nothing. Left everything as is. Stock all the way thru
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
I can get 5hrs SOT in normal usage after september update. But 3.5-4hrs in heavy usage. Actually I installed the update since it's available, but I noticed the battery improvement in the last 2 days idk why. Is it good?
[Samsung Galaxy S9  Real Life Review] polmdm:
I never reach 3 hours SOT, I have Exynos variant and every day both ANDROID SISTEMS and ANDROID OS register a massive battery usage. I don't know my phone drain so much the battery. Any ideas?
[Samsung Galaxy S9  Real Life Review] *Detection*:
Factory reset seems to solve it for at least a while
[Samsung Galaxy S9  Real Life Review] polmdm:
Nope, I've tried that solution some months ago and except having lost all data and accounts, battery drain was still consistent.

Today I'm using stock theme and stock lawncher to verify that third party don't use the battery too much.
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
I am using the stock theme and launcher since I bought the phone, and the android system battery consumption is also very high. I tried to disable the background activity but battery life is the same. Have you installed the september update? It improved the battery life for me, even if android system is still taking a lot of battery .
[Samsung Galaxy S9  Real Life Review] Lord-Frost:
Hey, just got an S9 (Exynos, Dual SIM)! Yes, I know I'm late to the party, but had to wait till my old phone finally gave up on me... xD

So, it's been only 3 days now, but I'm getting a less than ideal battery life... 3 hours tops SoT maybe. I read this whole thread but there were conflicting suggestions as to how long it takes the battery to settle. So, could someone clarify that for me?

Usage:

No social apps (except the occasional LinkedIn).

AOD on (0700 - 2300), black wallpaper, FHD, only FPS, no Iris/Face

Loc off.

Almost always 4G/3G (Terrible WiFi at my Uni)

NFC, BT, WiFi, background scanning, etc off.

P.S. I am using Nova Launcher though. But that won't affect battery much, right?

EDIT: Did the October Security patch update...
[Samsung Galaxy S9  Real Life Review] elliott2456:
Try turning off AOD I have noticed the people on these threads with the best battery life are the people who watch Youtube videos on their phones for 5 hours straight.

Even on my old S7 edge which had incredible battery life at the time AOD was taking up 2% an hour which adds up over 10 hours while the screen is off. So 2% suddenly becomes 20% which is an extra hour.

On top of that the Exynos version is a power hungry monster and the schulder is garbage (Each update the Exynos version gets better in terms of battery life and performance).

Try to put your phone on a 1080p screen res. It does help because most Samsung OLED/all Smartphone OLED panels are sort of natively 1080p and a quarter lol.

Read this: https://amp.reddit.com/r/GalaxyS8/comments/695l1g/basics_on_pentile_amoled_displays_the_real_reason/

Which can save some battery life.

Nova shouldn't affect your battery life. I know Action launcher doesn't affect mine.
[Samsung Galaxy S9  Real Life Review] Lord-Frost:
Will try that. Though it is basically off most of the time. Like, in class it's in my pocket always. And after class, I mostly keep the phone flipped. And I think under those cases, the AoD is off (right?). What I usually use AoD is for quickly checking the time/notifications.

I'm hearing that a lot... :'D

Done.

That's a relief... I don't like the stock launcher...

I've attached a screenshot. Overnight usage. (Battery dropped like a brick yesterday, so had to top it up by night).
[Samsung Galaxy S9  Real Life Review] nicolasmart:
The Mi A1 isn't even close to crappy, kiddo
[Samsung Galaxy S9  Real Life Review] Flora K Ragsdale:
6 hours per day at least.
[Samsung Galaxy S9  Real Life Review] jasperscheper:
Max 3h SoT...

When using youtube on WiFi with everything turned off 5h.. Disappointed in this phone!
[Samsung Galaxy S9  Real Life Review] TechnoBOY*:
Poor SOT sny suggestions??View attachment 4642421
[Samsung Galaxy S9  Real Life Review] edisonpaul4:
I always get with heavy use 4h - 6h SOT, Wifi almost always on, location on, 4G always, bluetooth off...

I have a Snapdragon variant.
[Samsung Galaxy S9  Real Life Review] mostling:
Bought an S9 last week and battery is the worst i ever had on any phone, image is from today, i streamed 4 albums on Spotify otherwise didn't use the phone much and as seen only 1 hour SOT so far.

Good thing i didn't sell my P20 Pro yet so i'll be going back to it and sell this piece if crap...
[Samsung Galaxy S9  Real Life Review] elliott2456:
There is something wrong with the apps that you have on that phone, like why do you have two battery percentage indicators? I am guessing you have the Exynos version of the s9? Which is notorious for having bad battery life.Try and import the snapdragon version of the s9.

I do feel you since I have the Exynos s9+ and I feel like I could get better battery life with the snapdragon version. Although comparing the P20 Pro with it's 4000mah battery to the s9 with it's 3000mah battery (Probably Exynos) I can see why you have issues.
[Samsung Galaxy S9  Real Life Review] mostling:
I do have the Exynos, the second % is Accubattery, running it to try to see what's going on.

I'm not giving this phone a second shot, i might try the S10 but i guess i'll have to go for the + version.

Too bad since i was starting to like the phone but really not a good first impression of Samsung for me.
[Samsung Galaxy S9  Real Life Review] Neith74:
Really poor SOT and battery life over all. I don't charge it at night not letting it drop below 20%, black wallpaper, all apps in Always sleeping apps (except WhatsApp, messenger, Google pay), location on battery saving, disabled "pink" packages with Package Disabler. Mid battery saving mode.

Nearby WiFi and Bluetooth scanning turned off, "keep mobile data turned on" disabled.

Otherwise I am really happy with this phone but I am considering selling it while it has some value and but a Note 9 (128GB, Duos 727€ new in my country)

Uploading a screenshot gives me error..

63% of battery, 1:20 SOT
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
I also have this huge battery drain, but sometimes I feel like it's good, I mean it's not bad for me, but it's very bad for the price. Otherwise I love the phone, it's just amazing. Actually I loved the S9's rounded and smaller design more than the squared and big design (especially for my hands) of the note 9...
[Samsung Galaxy S9  Real Life Review] Neith74:
Exactly. When I don't need the phone I can get 4 hours SOT, when I need it I hope for 1,5 hours.

Today I played with Note 9 at store. It's not as big as I thought it will be so that's amazing and I am seriously considering change to Note. Maybe after Christmas it will drop a little bit on price
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
Good :laugh:, I was thinking about it but I tried to hold an S9+ and a note 9. Compared to my phone, I feel that they are too much big for my hands, because I use it a lot with one hand. That's why if I wanted to change my phone i'll always go with the smaller S version.

I heard that November update had improved the battery life of the note 8 and the note 9, hope that this will be also the case for the S9...
[Samsung Galaxy S9  Real Life Review] Tomek Krakowski:
Hi guys!

I am a bit obsessed with battery life stats and here's my few words.

Using AccuBattery and GSam Labs I was checking the drainage in lots of different scenarios. With data, wifi and all that the sleeping S9 should not take more than 1% per hour. In fact it takes some 0,7-0,8 in my case. I don't really like too many unnecessary distractions, so I don't have FB and Insta and use them in a browser if needed, so not too many notifications, but generally the S9 is my mobile office and I use it quite a lot. When using regularly the phone can last up to 6 h SOT, the biggest drain is done by the GSM radar (I work in an old house with thick walls in an old town of Kraków so there it drains pretty quickly). When at home it is usually some up to 1%/h screen off and some 15% screen on (so that makes it over 6 hours of constant use).

And now the HIT! When I left it for the night with flight mode just to test it the phone lost 1% in some 8 hours, AccuBattery officially said it drained 0,1% per hour! 0,1%, did not spell that wrong!

I was actually quite shocked as I was doing this test some 2 months ago it was some 0,4-0,5%/h - I guess that the newly installed One UI/Pie might have helped. All in all it is not bad although the GSM eating so much is bothering me a bit.

That is that record night on GSaM Labs:

[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
This is the best battery life I've got since I got this phone... S9 Exynos - Oreo with november 2018 security patch. I hope it will become better with Pie update :laugh:
[Samsung Galaxy S9  Real Life Review] dimitrispas22:
I am very disappointed, the galaxy a5(2017) and my iPhone 6 battery live is better than this :(

how is that possible :( even factory resetting the device didn't help ...
[Samsung Galaxy S9  Real Life Review] Ckesery:
I got some issues myself so by no means i’m an expert but, that does not look well.

How long do you have the phone for?

You could try to RMA it?

Or maybe reflash with Odin? Not sure how that works though.
[Samsung Galaxy S9  Real Life Review] dimitrispas22:
from the first day (1st of October)

almost 4 months

I tried to flash android pie firmware with success but the battery remained the same( Knox is still 0x0 because is an official firmware)

RMA apparently my friend sent his s9 we bought them the same day in different stores due he made a contract ....the reflashed the firmware but it did not help

I am very disappointed and I regret not buying the s9 plus or note 9 (sometimes even why i didn't bought an iPhone or the oneplus 6/6t) ( i thought about buying the s9 and add safety net (free screen replacement for 2 years in case I drop my phone )

and I paid 700 euros
[Samsung Galaxy S9  Real Life Review] Ckesery:
On the exynos with 256gb, i got around 6 hours of SOT, while only slightly browsing and a bit of social media. However, i run trough several other issues aswell. Like the play store crashing after factory rwset, or the phone not going into sleep because foogle play store and some others keep running in the background.

I know this phone can work like a charm. But the amount of headache it gave me, makes me want to smash it and buy another iPhone..

I can’t really afford it tho, and i beleive that is the real problem..
[Samsung Galaxy S9  Real Life Review] dimitrispas22:
I reported again my problem with Samsung

But because i live in Cyprus technical support is for trash :(

When i had nexus 5x and it got bootloop deasese i had to pay 180€ for a new motherboard :(

And they said that there was not official statement for that problem ... Now the same gonna hapen with my s9 they gonna kick me out of warranty for no reason
[Samsung Galaxy S9  Real Life Review] Ckesery:
You can never be sure about it. Remember to not become emotional when you speak to them.

You should still try and RMA it. I don’t know how hard it is with samsung, but it’s better to try and fail, than not trying at all...

/edit

I take back what i said earlier. After a factory reset "to fix some other issue" i now get 4 and a half / 5 hours of SoT, instead of 6 to close 7.

I don't remember owning an phone this frustrating ever.
[Samsung Galaxy S9  Real Life Review] assist4tech:
Screen On Time was lot better on 9.0 Beta version. Post release of final build it has fallen below 4 hours. I am a heavy user of YouTube and Asphalt 9 and so can easily note the difference.
[Samsung Galaxy S9  Real Life Review] paulyz:
So, battery life and SOT on s9 crap like was on s6?
[Samsung Galaxy S9  Real Life Review] dimitrispas22:
yes(for most people)

I don't know about the Snapdragon variant (but for Exynos is crapy)

I am wondering about custom roms how good is the battery there...

I want to try them but I will lose my warranty :( it's not like google pixel which you gonna restore it with factory image and lock the bootloader and they ain't gonna find it that easy... on Samsung, the Knox will trip

and you gonna loose Samsung pay and health (Samsung pay I don't care since it is not supported in my country but for the s health I find it useful)

---------- Post added at 11:47 AM ---------- Previous post was at 11:42 AM ----------

I have a question here in Cyprus is the only country which if they don't find anything wrong about the phone or if its faulty by your own fault they gonna charge you 25 up to 75 euros for doing nothing?

(Apple charges 30-35 depends on product, samsung 25-30, and Asus 75 for everything even for 120 euro phone :laugh: :silly: )
[Samsung Galaxy S9  Real Life Review] Ckesery:
I guess it depends on multiple factors.

Depends on company, product, and law, and a few others.

For example, if i have an faulty Samsung fridge in the Netherlands, they will come and check it free of charge the first time.

If you complain again, they come, and don't find anything, you will have to pay. They do warn you however, and customer support aint that bad.

In the Netherlands, we usually don' get charged for RMA.
[Samsung Galaxy S9  Real Life Review] waingro808:
4 hours and 50 minutes SOT with 25% battery remaining is considered Good. Your expectations are way too high.

---------- Post added at 10:28 AM ---------- Previous post was at 10:24 AM ----------

I see Spotify. How long were you streaming music?
[Samsung Galaxy S9  Real Life Review] dimitrispas22:
about 3-5 hours a day at school with earphones, 98% of the music there is downloaded!

plus i found a way to fix battery drain! (trip the Knox and install the lightROM !)

still 39% left!

Yeaap me too. Pie indeed had some improvements for battery life, especially in standby time.

In oreo, I barely get 4h SOT @15%, and now it ranges from 4h to even 5h sometimes.

And in my opinion, just enjoy your s9, because the more someone complain, the more they wont be contented, considering all that speed it offers and the screen quality it brings, just superb
