Apparently Snapdragon has better battery life and better gaming performance too. I have exynos and battery life is not bad, not good either, but gets me through the day with just enough capacity. Charging is very quick though ( though i wouldn't recommend turning on quick charge unless needed). Be careful, snapdragon's bootloader is locked so if you're gonna do modification there might be issues, though i don't think you'll need to or should because that'll disable a lot of features on the S9. How are you gonna get snapdragon when you don't live in US nor China?

Just bought mine 2 days ago. The first day of use was very bad.

And yesterday my battery was so good even if I was only using WiFi
[Samsung Galaxy S9  Real Life Review] Cristi10:
This was today. I was away most of the time, so i was on 4g a lot (i don't turn off the toggle unless i am on wifi). I say it's pretty good, considering i used battery sucking apps lile fb amd snap. Everything is stock, at wqhd+, probably can squize a little bit more if i use a dark theme.

EDIT: Sorry i have s9+, wrong thread
[Samsung Galaxy S9  Real Life Review] varun.gid:
what i have noticed on exynos version is the LTE drain is much higher than WiFi. Only Wifi i can easily reach 5 Hours and on LTE almost 3.5 hours

Ahh i have to get the Snapdragon version now!
[Samsung Galaxy S9  Real Life Review] neeraj bhide:
I've had the S9 Exynos for about 20 days now and trust me I always get around 3 hours SoT. I use normal mode witb AoD off, location on the resolution i use is FHD+ and most of the usage is WhatsApp, Netflix,Instagram, Snapchat, mails and calling. Attached is the screenshot of my battery logs. To all of those who get 4-6 hours of SoT can you suggest me anything I should do?

S9 update

When you guys get the s9 april update, has your battery life increased? I haven't gone through a full cycle yet but will update a screenshot once that happens in 6 hours or so.

Currently at 2 hours 40 mins with 53% battery left. Samsung S9 (regular) exynos.

S9 sot

Im very disappointed battery life at my s9 with exynos. Averge sot are 2-3hours. Phone are connected with gear s3. Aod are on, internet trnasmision also on. I saw the lte drain battery and other mobile connection at the internet. I have phone only 5 days, but when I see yours sot 4 and I can't believe it.
[Samsung Galaxy S9  Real Life Review] stevenl23:
Give it some time.

What i'd recommend is getting a dark theme from the theme store (I use Black_Edition_V2)

Turning on battery saver to only decrease screen brightness by 10%( you can't really notice a difference visually but should help). You won't be able to use AOD though... your choice

Turn off location services when not using it or revoking permissions for most apps unless they really need it.

Give it a week or 2. Should settle by then. Just fully discharge and recharge it like 2 times a week for now. After a month just use it normally.

Go to connections, scroll all the way down, more connection settings. Turn off nearby device scanning

Go to connections, wifi, click the 3 dots on the top right, advanced, turn off turn on wifi-automatically and power saving mode if you wish.

Should improve over time, i've got a S9 exynos and can reach 4 hours pretty regularly. 5 hours a few times. Depends on your usage really. Send a screenshot here!

[Samsung Galaxy S9  Real Life Review] stevenl23:
That's not too bad, like you've been on battery for over 24hours and have had AOD on throughout quite some time. If you turned off AOD expect to reach around 3 and half hours over 24 hours with your usage. I'd say 5 hours of sot if you were to be on your phone a lot. Why don't you charge your phone overnight? or before you sleep if you believe that overcharging damages the battery?
[Samsung Galaxy S9  Real Life Review] thebehemoth73:
This... This is for the galaxy s9 not the s9+ ... There is twice as much RAM and a bigger battery so the phone should belong to it's owned forum... Most of the time when someone is getting 5 hours of SOT it's bc they own a s9+.....
[Samsung Galaxy S9  Real Life Review] Ryank02:
Battery life is amazing on my Galaxy S9 (Exynos Duos variant, G960F).

What I do notice, is that the GPU improved a lot in performance from my previous S7, but its also a lot better in battery consumption!! (see attached screenshots)
[Samsung Galaxy S9  Real Life Review] hryso:
I try add screenshot with battery use, but I can't. I have some problem with that. Sorry:/
[Samsung Galaxy S9  Real Life Review] ok4n93:
Try also to clear cache in recovery and after the reboot disable the background functions of the Android system in battery topic.

I can reach straight easily over 6 hours of SOT with straight use. Over a day about 4 hours of SOT with 16-18 hours of total usage.

It took me very long and a lot of disabling and other stuff to get it but now it is really okay.

Further software updates by Samsung should improve it as well.
[Samsung Galaxy S9  Real Life Review] hryso:
I'm too think about clear cache and made factory reset. And im made that. Now is better, sot are almost 3h but phone are use more than 20h ?

Samsung s9 snapdragon. Best battery life I've ever had on any phone so far. View attachment 4500697
[Samsung Galaxy S9  Real Life Review] Rapier:
You're right, after that I've deactivated AOD completely and gained some SOT and standby time.

I usually charge overnight during the week but on weekends, since I don't go to work in the morning, I let it discharge completely before I charge it...and I remember it was over weekend when I posted the screenshot

I want to know how do I disable the wake up when touching around homebutton area?
[Samsung Galaxy S9  Real Life Review] Rapier:
You don't touch, you press a little bit hard on that area (either with or without your knowledge) and the phone wakes up.

You can disable this feature by switching OFF the switch shown in the attached screenshot

all stock.. but overnight my battery drains at least 10% in 10 hours for example. here i screenshot from morning with 100% to evening 22h.. about 5 hours SOT, which is not bad but if i charging it at late evening and get 100% in 22pm, tomorrow in 8 it remains 89% or similar. it is not normal i think.
[Samsung Galaxy S9  Real Life Review] manexxx:
^got similar results myself on s9.. Try to disable AOD looks like it drains a battery little faster.
[Samsung Galaxy S9  Real Life Review] tinko975:
But i like AOD. I dont want disable that feature..

Mine drained from 100 to 90 in just 7hrs with no sleeping of apps and no aod. So screwed idle time.
[Samsung Galaxy S9  Real Life Review] *Detection*:
Turn it off for 24 hours to test

Another member had a similar drain and had to factory reset, that fixed the drain
[Samsung Galaxy S9  Real Life Review] Mikolo007:
The phone usually lasts about 6 hours upon heavy usage
[Samsung Galaxy S9  Real Life Review] :
Standby drain is back, but I blame it on the time until the cache stabilizes itself. But using the phone I manage to get more SOT than before.
[Samsung Galaxy S9  Real Life Review] kyooohei08:
Drains eeven faster when you use mobile hotspot. The least I got on wifi is 4h SOT and with mobile data I only got 3.

last night from 100% to 93% in 8 hours sleep. at nigth my device is in do not disturb mode and AOD is turned off.. (22h-07h)

i am charging it fast from 21.30-22.30, unplug charger when reach 100% and green led light. and leave it beside bed and go to sleep. waking up at 6-7.am

on my wife S7 drops 3% during night, oreo stock, same settings..

my A520 have 99% in morning. only 1% drops on 8 hours sleep. even in oreo..

S9 oreo needs improvement. deep sleep not working right..

together android system and stand by apps drain battery over night, 5-13%, day from day.

Just bought the Exynos Galaxy S9 a week ago.

I got 4h 51m SOT in 1 day and 14 hours.

Battery saver was turned on at 10%, Location most of the time off, 4G and WiFi active all the time, FHD+ resolution, autobrightness, AOD off, no MicroSD, disabled "Allow background activity" for Facebook, disabled the Video Enhancer.
[Samsung Galaxy S9  Real Life Review] :
I disabled background activity for Android System (meaning some Bixby stuff). Let's see how that plays out.
[Samsung Galaxy S9  Real Life Review] tinko975:
It will turn on itself after restart..
[Samsung Galaxy S9  Real Life Review] :
You're right :'(
[Samsung Galaxy S9  Real Life Review] *Detection*:
I've killed Bixby and all corresponding services with that package disabler

I never use things like that, AOD too as I am pretty much always around a clock on a screen, and if not I`ll just turn the phone on

Pretty much disable anything that isn't on my every day list of used apps, and only background sync apps running are email and whatsapp, apps like twitter are easy enough to sync manually when I open them so no need for them running either

Had the phone a couple weeks now and idle drain is still next to nothing, I guess if you are using those sorts of things then you have to expect at least some extra drain

I also disable notifications, background data and background activity for every app I install that I don't need anything automatic from, my theory is if notifications are enabled, then the app needs to be able to run in the background in order to send them regardless if it does or not, along with the other two background data and activity toggles in Data and Battery sections of the apps info, those three settings to me say "This app will run in the background if any of them are enabled"
[Samsung Galaxy S9  Real Life Review] angelorodriguez:
the highest i can get is probably around 4 hours SOT and 24 hours on battery . I'am using apps like snapchat, instagram,facebook. Automatic brightness. Location on battery saving. .is snapchat the battery killer? even tho it doesnt show that its draining much in Battery usage?

Can anyone using snapchat, instagram, and fb reply and tell ur SOT / batterytime. thx
[Samsung Galaxy S9  Real Life Review] robertkoa:
I will be getting an S9 soon.

Question: I always have location 'off ' UNLESS I am using GPS - a lot of silly Apps want to turn location

'On' but I really don't see the point for Facebook or Tagged to know where I am.

Do most of you have location ' off '?

May add an hour to your SOT...
[Samsung Galaxy S9  Real Life Review] ja-ki:
Since the last update battery life improved for me.

Aod is on at medium brightness, WQHD+ resolution, battery saver to medium (only for the - 10% brightness).

I get around 8h of SOT

Edit: Exynos Variant
[Samsung Galaxy S9  Real Life Review] robertkoa:
I will probably get the S9 very soon.

I hope to get 5 to 6 hours SOT using :

1080 res at 30 % -40% brightness.

Location OFF EXCEPT when using GPS.

'Always ON' Defeated

Tmobile Qualcomm Version

Web Browsing , Talking , Music Play, Iheart using like a laptop for business , Snapseed Edit

No hotspot always LTE 4G etc.

This is how I use Galaxy Alpha ( Exynos hi res Audio with 2 extra batteries ..lol )

Will this work ? I hate losing ability to replace batteries ( I have charger to charge spare ).

Like the quicker performance of S9, great audio.

Will lose the ruggedness of Alpha and batteries and rebootability of removing battery .
[Samsung Galaxy S9  Real Life Review] *Detection*:
Location (GPS) only activates for a very short time when location is requested, it does not stay connected and locked onto satellites 24/7 so the battery usage is minimal

I leave mine on 24/7 and get around 6-7 hours SoT
[Samsung Galaxy S9  Real Life Review] :
I used BetterBatteryStats to monitor my phone during the night. Since the latest version, you don't need root to see what's happening, you can just use some basic commands.

This is what I got.

[Samsung Galaxy S9  Real Life Review] Pag0n:
I have the Exynos variant of the S9. I am getting about 14% battery drain per hour with the screen on, which is alright with me. This results in a little over 7h SoT of continuous use.

My setup:

Big CPU cluster underclocked to 2314 MHz (no speed change in everyday use)

WiFi on 90% of the time, 3G when on the go

No location, bluetooth, NFC or AoD.

Bloatware removed, no Facebook or other draining apps

Most of my use is Chrome, Reddit, Imgur and Instagram

I used to have the OnePlus 5T, where the battery life was phenomenal. I got around 8-9% battery drain per hour with the screen on, which resulted in 11-12h SoT which is insane. No underclocks by the way.

From 94% to 39%. Calculated 14%/h of SoT with internet and reddit browsing with music playing from the speakers. Night time drain is a few % with no internet or WiFi.

I'm surprised! My Exynos lasts about 3-4hrs max. And that is with AOD off, CPU limiter on, FHD and -10 brightness. When did you receive the last update?
[Samsung Galaxy S9  Real Life Review] :
Used BetterBatteryStats to monitor battery during the night without Wi-Fi/Location active.
[Samsung Galaxy S9  Real Life Review] filou76:
I did quite the same. Usually my S9 loses ~ 5-6 % over night (8h, AOD off, Wifi on). BetterBatteryStats shows that it's mostly system wake locks, no special user app.

When I put phone into airplane mode it loses ~ 2% over night.

I don't see what could be done here by us. Anyone knows better?

I really hope Samsung improves this. I've been used to getting 1% loss over night from my old sony phones.
[Samsung Galaxy S9  Real Life Review] :
I think this can be related to the modem. Maybe [MENTION=4369943]*Detection*[/MENTION] can complete me, since he knows these issues better.
[Samsung Galaxy S9  Real Life Review] *Detection*:
Yea if it is system wake locks, without root nothing really can be done, and even with root I'm not sure what could be done tbh unless you knew 100% what the cause was and Samsung actually listened and did something about it

If it is the modem, flashing one that doesn't cause that drain might work, but then again it could be related to your SIM / Carrier / Signal too, has anyone with drain tried ordering a new SIM from their carrier?

Just tell them the phone keeps saying Insert SIM and you keep losing signal, but your friends SIM works fine, they should replace it free of charge

Or buy a cheap Pre-Pay SIM and put that in overnight, see if the drain still occurs

With your BetterBatteryStats log you'll be best just going through it all and looking for every entry that shows high battery drain, list all those in a post and we'll see if any of them are unusual

No clue about the logcat, would need a dev who knows what it all means to look at that
[Samsung Galaxy S9  Real Life Review] Pag0n:
Does it really matter though? The difference is 1% which is nothing. Like said above it's propably just system wakelocks which can't really be limited.
[Samsung Galaxy S9  Real Life Review] filou76:
The difference is 5-6% Samsung vs. 1% Sony ;)

So Sony does this MUCH better
[Samsung Galaxy S9  Real Life Review] Pag0n:
Did your old Sony phones use 1% battery overnight with internet on? If so, then that is beyond impressive. Never heard of that before.
[Samsung Galaxy S9  Real Life Review] :
2% on the XZ1 Compact. Battery is amazing
[Samsung Galaxy S9  Real Life Review] *Detection*:
Can't really compare different devices idle drain though, you can compare S9 vs S9 but different hardware, firmware and battery capacity / manufacturer all play a big role in drain

Obviously if one battery is 3000mAh and another is 4000mAh, the larger battery will show less drain, takes longer to drain 2% of 4000mAh than 2% of 3000mAh with the same usage (unless there is a severe problem)
[Samsung Galaxy S9  Real Life Review] :
The logcat isn't that important, I just posted it for the sake of it. I just did a test yesterday/today (standby during the night with Wi-Fi and location/with them disabled). And got 4% difference. Posted both BBS texts here.

I have a 4G SIM card (new one) from the best provider from the country (I'm employed there). I used to have another 4G SIM card from another carrier in the beginning, but battery life was more or less the same.

4% during the night doesn't seem to be a modem issue (it should be more like 20% to be considered an issue), but the abnormal standby drain is there (compared to other phones) and is shown by the Android System consumption presented by me in both of the txt files.

Our best guess is what's happening in the hood, and the cost of the features (like AOD, QHD+, Dolby...etc) along with some drain from the Samsung Apps (I didn't debloat after the last factory reset ~Friday) and the drain isn't different at all since last time when I disabled everything, which is insignificant.
[Samsung Galaxy S9  Real Life Review] filou76:
this is true of course. but sony does this really much better. i'm quite happy with the overall battery consumption, i.e. SOT, of the S9. my old sony z3c wasn't that much better in case of heavy use. but battery drain without using the phone does make me a little angry ;). if it's just laying around with internet on the S9 loses 15% per day whereas the z3c lost 3-4%.
[Samsung Galaxy S9  Real Life Review] tinko975:
I have both S9 exynos and A520F. On oreo. S9 drains 7-9% overnight but A5 only 1%.. firmware related sure..
[Samsung Galaxy S9  Real Life Review] *Detection*:
Didn't we work out it was something to do with facebook / AOD in the end? When I enabled them and got extra drain overnight, I don't know if FB would be seen as a system app too as it is pre-installed? Along with the FB services I enabled too which likely are seen as system apps
[Samsung Galaxy S9  Real Life Review] :
We did. I'm just taking into account the others who have issues and no Facebook or AOD
[Samsung Galaxy S9  Real Life Review] *Detection*:
Yea, dunno it's been a random issue for some and not others since my first Samsung (S5), different firmwares seems to cause different drain, but you never know what people are not telling you too, like some claiming to get 8 hours+ SOT who are actually just leaving their phone on low brightness and screen on all the time without really using it, others with bad overnight drain who failed to mention they have 200+ apps installed all with background usage enabled, people who say they have reset 100% and not installed any 3rd party when really they haven't reset at all and are just looking for a quick fix that will never arrive (Change this setting for 3 more hours SoT lol)
[Samsung Galaxy S9  Real Life Review] feds1:
Hello all, how is your battery doing after some samsung/android updates? Is it working better? (S9, exynos, dual sim - plan to buy). thanks.
[Samsung Galaxy S9  Real Life Review] tinko975:
works ok. night drain 2-4%, daily usage normal, 4 SOT hours. no problem with latest firmware.
[Samsung Galaxy S9  Real Life Review] feds1:
Daily usage means how many hours? I usually disconnect at 7 am and returning home at 8-9pm so I am expecting that I will still have some remaining power until I go sleep. I don't want to check battery and searching for charger only to survive until I return home....
[Samsung Galaxy S9  Real Life Review] tinko975:
I am charging it in evening. Fast charging from 30% to 95% maybe in one hour. Unplug and leave overnight. In morning 7am have 92% and using it to 8-9pm. I am not heavy user, not playing games etc. Browsing, chat and maybe youtube and few calls.

Battery could be better, will see after 1 year. On S6 battery was very small and after 1 year capacity was not good enough to using it without charging in day. S7, 8 and 9 should not have that issue..
[Samsung Galaxy S9  Real Life Review] :
[MENTION=4369943]*Detection*[/MENTION] [MENTION=5586757]tinko975[/MENTION] do you have LTE Calls enabled on your firmware?
[Samsung Galaxy S9  Real Life Review] tinko975:
No..
[Samsung Galaxy S9  Real Life Review] :
The O2 build that *D-man* is using doesn't have it as well. I have a theory that the drain is caused by the firmwares that support LTE/4G calls. Since most people claimed there were no drains without SIM/Airplane mode.
[Samsung Galaxy S9  Real Life Review] robertkoa:
I am getting great SOT by using

AOD off

Location OFF turn on manually for GPS

Most Apps can't notify me ..

Used for Emails lots of browsing youtube etc.

TMobile new Phone not tied to Tmobile Contract fully paid but used on Metro PCS always on 2 to 4 sometimes 5 bars of 4GLTE.

Brightness about 30% -was using negative color and thought it was helping a little now use a dark theme but on Web Browsing that does not matter.

SOT way over 7 hours .

There is a HUGE software update for Security almost a Gig of Data - I KNOW this will screw up the phone ...lol.
