[Samsung Galaxy S9  Questions & Answers] preambean:
I got the SM-G9600 (SM-G9600/DS) online from Hong Kong and am using it in Australia. It works perfectly here straight of the box. Works with the full range of 4G+ (LTE) networks. The only thing that doesn't work is the VoLTE (though once a method for root on the snapdragon s9 is found, a CSC change would change this).

Would recommend.
[Samsung Galaxy S9  Questions & Answers] nelsyv:
Awesome! If you don't mind me asking, where did you buy it? I've seen some on Amazon, but I'm not sure the best way to import it. I think ideally I'd get either a Hong Kong or a Latin American one (I hear the Chinese ones tend to have some bloat added), but I don't think I'll have an easy time specifying which kind to an Amazon merchant, ha.

Since the bootloader is unlocked, I don't think getting root should be tremendously difficult. Hopefully that means it will come soon :fingers-crossed:
[Samsung Galaxy S9  Questions & Answers] preambean:
I just bought mine off ebay. Best option for here in Australia.

Ok as you know the phones with the Xynos chip has pretty rubbish battery life but I've found a temp fix until samsung hopefully fix the issue. You won't notice any slow down or compromise the use of your phone.

All it is is set your phone to mid battery save and keep all the settings on but limit the cpu.

You can still play all the latest games without a stutter, you can't tell the cpu is being throttled.

Try it for a day see what you think, I also have Always on Display turned off for extra savings.
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
Interesting, will give it a try today, been averaging 3h40m for 50% battery usage (Not run it down to 0% yet) so will be able to see if it improves much

Says it has added over 4 hours to my battery life estimate
[Samsung Galaxy S9  Guides, News, & Discussion] SponTen:
Thanks for the suggestion, will be testing soon.

My issue with my Exynos S9 is the standby. It's not completely terrible unless I'm in a crowded bar or an area with zero reception, but I can never get it to be good. Even with everything disabled (location, sync, AOD, lots of apps, etc) I can't get it under 1.5% drain per hour. With it all on I can easily hit 5% drain per hour, sometimes more, which is weird, cause the actual SOT doesn't take much more than this; 8-10% when stationary on WiFi, 12-15% when moving on mobile data.

Seriously the SOT on this thing is great (FHD+, haven't tried QHD+ yet). I reckon I could easily hit 7 hours, possibly getting up to 10 if I'm just browsing/watching shows in bed all day. But dear god the standby is driving me nuts.
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
Standby drain will be higher if your phone is in a pocket, doze only kicks in when the phone is sitting completely still so no sensors are active like gyro etc (unless that has changed in Oreo)

So standby overnight should be significantly better than when you're out and about with it
[Samsung Galaxy S9  Guides, News, & Discussion] SponTen:
Yeah makes sense, but it still drains 1% per hour overnight, whereas other phones I've used only drain about 0.5%.
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
1% or even 0.5% per hour is a bit much tbh, I see about 2% drain for around 8-10 hours
[Samsung Galaxy S9  Guides, News, & Discussion] SponTen:
That's also the consensus I've been seeing elsewhere.

No idea how to fix. Seems that only my HTC 10, which has horrible SOT (drains about 25% per hour) can get standby this good, and yet it's still worse than most other people's.

2.5% per hour on average during the day with location and sync (but not AOD) on is actually good for my S9, yet it's still poor compared to everyone else's it seems. Today, with location and sync off, I'm averaging 1.5% standby drain per hour. AccuBattery staying 86% deep sleep, whereas it's closer to 65% when location/sync are on.

idunnolol, maybe I have poor signal? I'm usually on 2-3 bars. Or maybe an app I use is sucking power? ¯\(°_o)/¯
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
There's a few people with this drain problem and up to now we're starting to think it might be related to the modem, as with the SIM removed the extra drain is gone

It also looks like it might be related to which region/CSC firmware you have running, I am running the United Kingdom O2U firmware and do not see this extra drain

But this is all theory / guesses right now, nothing solid
[Samsung Galaxy S9  Guides, News, & Discussion] SponTen:
Yeah makes sense. I'm in Australia, not sure how to find my firmware version. I'm guessing it's in Software Information? But there are a lot of numbers.

I find the Exynos modems seem a little worse than the Snapdragon ones where I live, though it could just be the specific places where I work and travel.

Samsung Phone INFO app from the play store will give you all the info you need
[Samsung Galaxy S9  Guides, News, & Discussion] Deleted member 5746995:
I think I isolated the issue by disabling extra packages last night, but I don't know which of them. Will see after tonight for sure.

Can you please enable aod (even though it will be turned off between 12-7AM) and the facebook packages for a night? It will help us narrow down the issues.

I used your settings - fb -aod and still had drain.

Will flash the O2 firmware if the drain continues overnight.
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
Yea sure, so enable AOD but set it to turn itself off between 12am-7am?

Enable FB packages

I`ll set that all up tonight, then charge to 100% before bed, see where it is in the morning
[Samsung Galaxy S9  Guides, News, & Discussion] Deleted member 5746995:
Thanks. Would've done it myself, but I want to know if disabling some of the services isolates the issue.

Maybe it's AOD+FB or other issue (that I might've fixed by mistake). Took this post as a reference: https://xdaforums.com/showpost.php?p=76543514&postcount=49

Disabled some of the packages until I got bored + the ones you disabled.
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
I've always disabled both tbh, only left FB package manager or whatever it is needed for the GearVR on my S7 for a while when I was using the Gear, but got bored of that and disabled them all, AOD gets disabled straight away, phone definitely cannot be as deep sleeping if that is active, and the screen is using power the whole time too, albeit only the pixels that are lit, but still more than having it 100% off

I tested with AOD on and off on my S7 and got huge overnight drain with it enabled vs off, same throughout the day, the phone couldn't enter Doze fully iirc
[Samsung Galaxy S9  Guides, News, & Discussion] Deleted member 5746995:
I didn't think AOD will drain battery since it's turned off in that interval? I had a OK drain after factory reset with AOD on. So idk what the hell is happening.
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
I meant when I left it enabled and on the display the whole time, different phone and different version of Android though

Maybe after the factory reset, because the system apps are back to their original versions, drain is OK, then when they update back to the newest the bug is brought back? Or are you updating everything 100% before testing?

Samsung system apps get updated from the Samsung app store too so you'd need to sign into a Samsung account to update those iirc
[Samsung Galaxy S9  Guides, News, & Discussion] Deleted member 5746995:
Everything was up to date before testing. So I have no idea what is causing the drain to lag.
[Samsung Galaxy S9  Guides, News, & Discussion] SponTen:
I think I'm on ARD4? That's the last 4 numbers of Bootloader and PDA Version. CSC is ARCA and Baseband is ARD6.

I've already got FB disabled, amongst pretty much anything unnecessary. Although I do use FB Messenger as everyone where I live uses it.
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
ARD4 is the firmware before latest, apparently the latest BRE5 fixes some drain bugs and other things

---------- Post added at 11:46 ---------- Previous post was at 11:45 ----------

Ah well, we'll see tomorrow if FB / AOD causes it for me, if not then at least you've disabled whatever was causing it

Export your package disabler list and save on a PC for future in case you reset again
[Samsung Galaxy S9  Guides, News, & Discussion] SponTen:
I have heard that. Will defs be testing, cheers.
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
OK so I've enabled the facebook services, updated the FB app to the latest, enabled AOD and set it to a normal clock and left the default of 7am-12am so it will be off between midnight and 7am

Will check back in the morning with the result
[Samsung Galaxy S9  Guides, News, & Discussion] :
5% drain with all that I have disabled....fml
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
Exactly the same for me with FB and AOD enabled, went to bed with 98%, turned the phone on this morning, just saw the % change to 93%

11pm > 7:40am (8h40m) = 5%

Usual drain = 2% with those two things disabled
[Samsung Galaxy S9  Guides, News, & Discussion] :
So those are da issue.

Thanks for confirmation
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
Yep, definitely seems like it, I'd put a bet on FB even though I don't have it set up or have an account, they enjoy phoning home in the background

In fact I can check, I have a DNS request logger on my network, should show any activity from my phone overnight

A few entries through the night for these two, but nothing significant, must be the app/service itself, or AOD

Tried it out, still getting 4h SOT
[Samsung Galaxy S9  Guides, News, & Discussion] Revontheus:
I've found that installing a custom kernel and underclocking the CPU also helps.

Also, using Greenify to hibernate offender apps, namely, Facebook, Messenger and other social media applications also helps with the SOT. The Job Scheduler wakelock of facebook wakes the phone up from deep sleep often so it's worth hibernating the app.
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
Ah yea, if youi're happy to trip KNOX with root / custom then there's nothing stopping you finding out exactly what is causing drain and stopping it, problem starts when you do not want to trip KNOX, and have no root
[Samsung Galaxy S9  Guides, News, & Discussion] kyooohei08:
Hi guys, I've followed user XDA Detection's guide. I disabled background activity for most apps including Facebook and Messenger, and disabled the background data usage for theem as well, I still receive notifications from theeem so it's really worth the try. Another thing is turn on Power Saving mode to medium, just turn on the CPU Limiter and allow background data usage there, no screen brightness adjustments and no AOD, Im still in WQHD so I think this is really great battery life because I get consistent with the 5h or more SOT.
[Samsung Galaxy S9  Guides, News, & Discussion] Paul Curry:
Thanks for the suggestion, will be testing soon.
[Samsung Galaxy S9  Guides, News, & Discussion] Revontheus:
Most of the time, battery problems are caused by over management. Android Doze on Oreo on its own is actually pretty good at managing things on its own and blocking wakelocks, services, alarms and etc. without sufficient knowledge creates more problems than already is needed.

That being said, you have a good point and not every user has the option to root and trip Knox though it should be noted Android pay works fine for me with Magisk and Systemless Xposed.
[Samsung Galaxy S9  Guides, News, & Discussion] *Detection*:
Yea some people go overboard with disabling things, but I think in most cases it comes down to poor SoT with 100% untouched stock

Doze is fine, but SoT is the main thing people are wanting better battery life for, tbh I'm not particularly fussed about doze, nice to wake up to the battery pretty much the same as it was when I went to bed, but not difficult to stick the charger in while I'm getting ready, and unless things have changed with oreo, Doze only kicks in when the phone is 100% stationary, if it is in a pocket and moving about, the sensors prevent it from kicking in anyway, so unless you sleep 4 hours from a charge point...

Tripping KNOX with a £760 phone is not an option for me, I need my warranty, plus I use Samsung apps that break / become a PITA to get working again if it is tripped, and tbh I only ever rooted to kill ads, and I have that pretty much sorted without root anyway so I don't miss it
[Samsung Galaxy S9  Guides, News, & Discussion] SponTen:
Okay so idle drain and screen drain are two separate things. My idle drain isn't very good; I lose an absolute minimum of 1% per hour, even with location, sync, and AOD off, and a ton of services disabled, whereas I see most people lose less than 0.5% with all this stuff still enabled if the phone is just sitting there idle (like overnight). I don't think I'm ever going to reduce the drain to less than that as it must be something to do with my SIM card/carrier, the area in which I live, and potentially my Google account. But yeah, I keep location, sync, and AOD off; I've disabled most apps/services that I don't use and that can't be uninstalled (like Bixby); and I set a few apps to not run in the background through Oreo/Samsung battery settings.

For SOT though, I haven't specifically tried to do anything to improve its drain other than leaving the resolution at 1080p. It drains 8-12% per hour most days, though occasionally it will hit 15% per hour if I'm travelling while streaming music, for example.
[Samsung Galaxy S9  Guides, News, & Discussion] egk99:
First of all,Thankyou for taking the time to explain.

My current configuration:

Apps disabled:

Bixby

Aod

Chrome

All Microsoft apps

Disabled background activity for ANDROID SYSTEM

Auto brightness

Wifi spanning

Screen set to max resolution .

Enabled wifi power saving

I still only get 2.5 to 3hrs of screen on time.

I use mobile data all the time.

Turn on airplane mode before sleeping.

Lose about 2% every hour and 10% overnight even if the phone is in airplane mode.So it most definitely can't be the network that is causing the idle drain.I was using op 3t prior to s9 with the same carrier,didn't experience any abnormal overnight battery drain with cellular enabled.

We can only hope samsung somehow fixes the drain issues as the upcoming note 9 will also be powered by the Exynos 9810.

But this is totally unacceptable from a flagship product.Let's hope for the best.

Thanks again, have a nice day! :good:
[Samsung Galaxy S9  Guides, News, & Discussion] SponTen:
Oh jeez dude, that's horrendous, sorry to hear :(. Have you got location and sync enabled or disabled? There must be some bug going on with your phone or you've got an app/service spamming wakelocks in the background.

I used BK Disabler and disabled a ton of stuff. Here's my current list of disabled stuff. Some of it isn't necessary, but basically I enabled Developer Options > opened Running Services > found stuff that was running that I don't use > disabled them.

Hope that helps! You have a nice day too :D
[Samsung Galaxy S9  Guides, News, & Discussion] egk99:
I have sync turned on buddy! Location is off most of the time.

Received the june security update ota just now,weighing around 370mb.I'm hoping for the best buddy.

If all else fails,Im thinking of downloading the latest fw from sammobile and clean flash the same.

Thanks! :)
[Samsung Galaxy S9  Guides, News, & Discussion] BackDaws:
Set screen to fhd+ leave everything else on including location, goto battery save and choose mid leave sync turned on, turn off AOD as it is utter sh*t anyway, tick limit CPU.

Also have you disabled Bixby app and services for the apps menu or just done the usual turn off Bixby voice and turn off Bixby button then long pressed home screen and turned off Bixby home ?

I think you could be causing problems if you've disabled the actual apps themselves.
[Samsung Galaxy S9  Guides, News, & Discussion] Tel864:
FWIW, I have everything remotely related to Bixby disabled with Package Disabler Pro and no problems at all.
[Samsung Galaxy S9  Guides, News, & Discussion] BackDaws:
Does agk99 also have it all disabled using package disabler pro ?
[Samsung Galaxy S9  Guides, News, & Discussion] wezzel98765:
I have literally disabled bsolutely everything and even removed all social media apps and I am still losing around 12 percent overnight even with WiFi off during sleep and location off and every app closed.

I am so displeased with the battery life on this handset, had the same issues with my s8!

It looks as though the medium power save might solve this issue based on what I’ve read so that’s going to be my next solution. The only features I currently have enabled (I have used package disabled pro) makes my phone nothing better than a Old school Nokia but with wirsenbattery life and a fancy screen, which is other lowest resolution Anyway!

Getting around 2hours SOT currently, wil be testing with mid power Dave mode overnight and all day tomorrow and will report back. Just going to charge her to 100 then unplug before bed
[Samsung Galaxy S9  Guides, News, & Discussion] BackDaws:
I went from 100 to 96 from 12 last night to 8am, I get about 4-5 screen on time and I'm disappointed.

The US model is getting 6+ hours screen on time.
[Samsung Galaxy S9  Guides, News, & Discussion] babyboy3265:
Guys I have read all the comments in this thread, even though I am one of those who get about 6h SOT with AOD ON and no services disabled, other than NO SYNC and NO LOCATION.

I have concluded a few things:

1. Indeed disabling too many things is over-management, as the wise ones say: Too much of anything is no good.

On my previous phones I kept on disabling numerous things to save RAM, to extent battery life, speed up phone, and nothing ever really did what I wanted in the long run.

2. In the case you do not need some features like KNOX, do your homework, and install a custom ROM with a custom KERNEL. Best thing you can do for your phone. In the case you do that you will know whether it is software that is causing your problems or is it the hardware that has a problem. If some people have 6h SOT out of the box and others have 3h SOT with almost no difference in the settings, then a hardware bug stands a good chance.

3. I still do not understand the obsession some people have with leaving their phones uncharged over night. We live in the era of smartphones and lithium batteries. When your phone reaches 100%, the battery is not really depreciated, in fact, leaving it to drain overnight will cause more damage in the long run, than letting it reach 100% and leaving it that way until you wake up and unplug. No matter what you do, you cannot make that battery live for decades, it will depreciate one way or another. Enjoy the device and if one day necessary change your battery, not such a big deal. Starting the day with 100% battery is worth it. Period.
[Samsung Galaxy S9  Guides, News, & Discussion] Blubber120:
G965F with N9 Port and the Kernel that came within. So I think, all the issues are software related.
[Samsung Galaxy S9  Guides, News, & Discussion] Cloudane:
I'm seeing about 3-4/hour% drain here with it in my pocket. Exynos, AOD on, WQHD, default settings otherwise. I have a few bits and bobs running but am careful about what might hammer the battery and keep an eye on Gsam etc. Android OS and Android System are pretty high, with a fair bit of "IMS System" wakelock but that's part of the carrier I think (4G calling for one) so can't do much there...

TBH I've had numerous Android devices and battery drain has always been an issue in every single one. Multiple of these threads have existed for all of them. People proclaim they've "found a fix" or that it "seems to be better" after the latest and greatest firmware update but there's extremely rarely if ever any real lasting difference - all just natural Android inefficiency (especially if you come from iOS which really has a tight grip over the battery - unfortunately at the expense of freedom and flexibility). Some phones are affected worse than others but the issues are always there. You do your cache clearing rain dances or worse still, factory reset and have to set everything up again, and it goes back to how it was a few days later. If you have things enabled on an Android device, it'll drain, period :)

Having worried about battery life so much over the years (even going so far as to switching back to iOS a couple of times, and regretting it for different reasons) I think really the best thing to do is make sure you're never far away from a charger. Get a wireless desk charging cradle for work. Carry a battery pack routinely. Etc. Then you don't have to spend half your life micromanaging.

Actually, while they don't do very many updates via Galaxy Apps they do include them in their monthly security updates. That said, it's very rare to get new features. Samsung wants to be like Apple and convince the sheeple to buy their latest new phone to get new features. ;)
