my s9+ can achive min 6 hours SOT easy so try what i said cuz what u said is not normal and this method worked well for me on note 8 same as ur condition after factory reset and format internal memory the device works better and battery improved
[Samsung Galaxy S9+ Real Life Review] turtuv:
but can i risk to damage the phone with this factory reset and formatting (since the phone is brand new)?

p.s. how can i do the factory reset and format the internal memory?
[Samsung Galaxy S9+ Real Life Review] Galaxo60:
First week battery is horrible, because the phone is learning your patterns.

After a couple of days, it will stabilize.

Also disable background activity for Android System, because sometimes this drains a lot of battery and no one knows why. Disabling it doesn't have any side effect.

;)
[Samsung Galaxy S9+ Real Life Review] MaZaGnGy:
factory reset will not make any damage to ur device just delete all ur data and apps

how to do a factory reset : settings>general management>reset>factory reset

format internal storage : i dont see any option for that on settings but may be others can lead u anyway for me i do that from Samsung my file app select everything on internal memory and delete it

and make sure u backup anything important before doing this
[Samsung Galaxy S9+ Real Life Review] turtuv:
thanks for the suggestion! So do you suggest simply to disable background attivity for android system? that's all??

what's the first thing to do: factory reset or format the internal storage?
[Samsung Galaxy S9+ Real Life Review] MaZaGnGy:
try above method 1st may be it work for u if not

format internal storage 1st and then factory reset
[Samsung Galaxy S9+ Real Life Review] Galaxo60:
Yes, only that did the trick for me.

;)
[Samsung Galaxy S9+ Real Life Review] turtuv:
thanks again, i will try immediately! When will i see the effects of this settings tho?

edit: i have a problem: i tried to disable the background activity for android system, but after i rebooted the phone, it was active again
[Samsung Galaxy S9+ Real Life Review] Galaxo60:
You should let the phone to settle, maybe it will take 2-3 days to learn your patterns and improve battery life.

;)
[Samsung Galaxy S9+ Real Life Review] turtuv:
thanks, and what about the other problem? and last thing: can i have problem if i disable the background activity for google play service too?
[Samsung Galaxy S9+ Real Life Review] Galaxo60:
I wouldn't recommend disabling Google Play Services, because those are the base for a lot of applications and services.

;)
[Samsung Galaxy S9+ Real Life Review] mtm1401:
Won't damage the phone as they're all standard functions in the settings menu, I found that it made a difference after I installed OTA updates
[Samsung Galaxy S9+ Real Life Review] turtuv:
if i see that android system consume more than 7% of battery, i will do a factory reset. do you suggest to format internal memory too?
[Samsung Galaxy S9+ Real Life Review] Mano1982:
That's what i am talking about.

I was at work the whole day. I used my phone on my way to work, listened to music etc. Screen on time which you can see on screenshot is the time i used mobile phone on my way to work. It was 92% when i came at work. After that i didn't get a chance to touch my mobile the whole day, and when i finished work, it was already 67%. I think 25% without touching mobile is too much. On my old phone, with same usage i had lost only 5-6%.

And yes, i have done factory reset once, it didn't help much.

Seriously considering a custom ROM :crying:
[Samsung Galaxy S9+ Real Life Review] mtm1401:
Can't say I've done the formatting but the factory reset worked post update

Download GSAM and accubattery to get a better idea of what's been happening, looks like Google play was doing something in the background / your device wasn't entering deep sleep, ive been averaging less than 2% drain with the screen off. Also what's your signal like work (gsam can tell you that) as that makes a big impact
[Samsung Galaxy S9+ Real Life Review] Mano1982:
When i am at home & connected to Wifi, the battery drain is reasonable (not very good though), 1% or little more per hour. But when on mobile data, it goes so fast. Signals are ok at my work (not ideal) but i have had same signals with other mobile phones also.

I have installed GSAM now, so lets see what we find out :)
[Samsung Galaxy S9+ Real Life Review] mtm1401:
Yea I did a day at home on Wi-Fi vs mobile data only and you definetly lose some juice - it's the same with most phones though (seen people complaining on pixel/ one plus threads).

However given the rate of decline I would hazard a guess that something else is going on behind the scenes on your device

I also recommend betterbatterystats and granting permissions to monitor wakelock if the problem persists :)
[Samsung Galaxy S9+ Real Life Review] Mano1982:
That's true that it's with all mobile phones that you lose more juice on mobile data than wifi, but rate of decline with S9+ is too high in my opinion.

I'll try to install batterbatterystats. :)
[Samsung Galaxy S9+ Real Life Review] turtuv:
Disabling the background activity of Android system seems that solved the problem. I can save the factory reset for a future big update :)

I don't understand how it is possible that some people reach more than 5h sot with more than 50% of battery remaining. Unbelievable
[Samsung Galaxy S9+ Real Life Review] Galaxo60:
I'm glad it solved the issue for you as well, this is so weird option, but is the only workaround we have for now.

:)
[Samsung Galaxy S9+ Real Life Review] mtm1401:
I might give that a go myself, see if it makes a difference. Isn't a huge drainer for me but every little helps! (Hopefully the next big update brings a decent scheduler and more efficient use of the cores)

Theoretically it's possible, for example I've watched 40 mins of YouTube whilst on wifi this morning and only lost 5%, but that was continuous SOT. I think the general consensus is that the exynos is more efficient on standby but the SD is more efficient when being ramped so that will also influence some stats you're seeing.

The thing I've found most annoying is severe drain when listening to Spotify with BT headphones, seems when the device is ticking over but not in deep sleep it still loses charge quite quickly
[Samsung Galaxy S9+ Real Life Review] turtuv:
thanks to your suggestion, but i will check it after the next recharge :)

you can give it a try for sure. anyway in this days i didn't used the phone a lot, but the best sot time i got was 3h
[Samsung Galaxy S9+ Real Life Review] Galaxo60:
Just to notice, I did the test with AOD enabled (10AM-10PM) for this charge, and it takes me around 1 hour SOT:

:(
[Samsung Galaxy S9+ Real Life Review] mtm1401:
Still very decent longevity! Personally I turn the phone over if I don't want AOD on and leave it face up if I do, best of both worlds.
[Samsung Galaxy S9+ Real Life Review] turtuv:
but, is not risky for the screen if i turn over the phone? it seems that the screen can be scratched easily in that way

do you use normal settings (sync, auto brigthness, gps ecc)? i never reached those SOT's times :crying:
[Samsung Galaxy S9+ Real Life Review] Galaxo60:
Yes, everything synced and everything enabled. I have to have them enabled because I use Google Now, which actually asks you to enable most of the settings.

;)
[Samsung Galaxy S9+ Real Life Review] mtm1401:
I have a spigen thin case that has a slight lip at the top and bottom so it covers the corner and sits above the screen, as well as one of the neoflex screen protectors so no scratches for me :)

I recommend the case as it does a job and doesn't ruin the aesthetics of the phone
[Samsung Galaxy S9+ Real Life Review] turtuv:
what i have to do to get those sot hours??

i use a silicon case for the back of the phone, and it protect the corner too, but i don't use any screen protectors. i had never used the phone turned over, but i want to understand if the screen can get damaged if i do so. because if there is no problem for the screen, i can start to use AOD and to keep the phone turned over during the day :)
[Samsung Galaxy S9+ Real Life Review] mtm1401:
If you have a screen protector and a case that has a lip it should be fine to put the phone face down

Have you got the relevant battery apps installed? GSAM, betterbatterystats, accubattery? Hard to diagnose an issue otherwise. After turning off android system background activity I managed the stats below, but was on Wi-Fi all day.
[Samsung Galaxy S9+ Real Life Review] turtuv:
I have a cover similar to this, but i don't use screen protector. can i keep the phone turned over anyway?

i don't have any battery apps. which ones do you suggest to install? anyway you have a very good battery stats, i don't know how many days i have to wait until the battery settled itself
[Samsung Galaxy S9+ Real Life Review] turtuv:
Despite the background activity of Android system was disable, I got an high percentage of usage from that process. Have I to do a factory reset? :( very bad battery for now

If you keep your phone on a soft surface then the screen shouldn't get damaged. In my youth, I used to use a hanky or a tissue paper on which i used to keep my phone (no case no screen guard). I was pretty vigilant back then. But now I use a minimal case and a hydrogel screen guard (tempered glass is a strict no go for these curved screens).

I keep my phone face down when I sleep, on desk it is face up; keeping your phone face down helps power consumption in AOD. AOD is off when proximity sensor is covered for longer duration (in pocked, or when face down). Another way you can minimize AOD power drain is by having it enabled for a defined period (can be configured in AOD settings). Face down method gives you best of both worlds.

I get 6-7hr SOT and my Android System power consumption is also 10%

Are you keeping your location service OFF?

What I have notices is, that the android system power consumption will go high IF you have Location OFF while having "wifi and BT scanning for location" ON.

Android system is forced to look for location data via such scanning, and that increases its power consumption.

Disable background scanning and keep location always ON for more efficient usage. What you can control instead is app permissions to location. Allow only google services, maps, cab services, banking services to location access; that works better for me than controlling location sate.
[Samsung Galaxy S9+ Real Life Review] turtuv:
So can i keep the phone face down without problem?

I keep the location service off almost always, I keep it on only at home because I use smart lock with trusted location. I don't have wifi and BT scanning for location on tho.

I don't want to reset the phone if it is not necessary

[Samsung Galaxy S9+ Real Life Review] mtm1401:
Your android system will be high as you've not been doing much with your phone by the looks of it, if you used your phone twice as often, your SOT will increase but overall time on will decrease, it's just a trade off. Download GSAM battery monitor and follow the instructions to enable more stats.
[Samsung Galaxy S9+ Real Life Review] turtuv:
I didn't understood well, can you explain it to me again? I'm not English sorry

Inviato dal mio SM-G965F utilizzando Tapatalk
[Samsung Galaxy S9+ Real Life Review] mtm1401:
Sorry I didn't explain it very well - so there is a trade off between your SOT and your overall endurance (I.e. how long the phone lasts after being taken off charge.

My screenshot - 50% charge gone

4 hours SOT & 10 hours off charge

So by the time the phone dies I'd have 8 hours SOT and 20 hours off charge

Your screenshot - 65% charge gone

3 hours SOT & 30 hours off charge

So by the time your phone dies you'd probably have about 5 hours SOT and 48 hours off charge

If you used your phone heavily, the SOT number would increase, but the hours off charge would decrease.

Also because your phone is sitting idle, you aren't running any other apps, so android system will take a higher % of the battery as it needs to run for the phone to work (even if background activity is turned off). Again if you used the phone more heavily, the % of battery used by android system would decrease, but the actual amount of power used by it would stay the same.

Hopefully that make more sense? :)

Also as a personal note I find Samsung browser to be much easier on the battery than chrome, you can download an adblocker for it & works well with Samsung pass
[Samsung Galaxy S9+ Real Life Review] turtuv:
Crystal clear, thanks! I use chrome because I have all my passwords, bookmarks etc synched

If this makes you feel any better - these are my stats after being out and about today.

I really struggle to understand how the difference can be so large off and on Wi-Fi.

On Wi-Fi and doze it drains 5% over 5 hours, when I'm out and about I lost 5% in the 90 minutes whilst I was playing football
[Samsung Galaxy S9+ Real Life Review] mtm1401:
Didn't attach the screenshot
[Samsung Galaxy S9+ Real Life Review] Cristi10:
This is from today. Spotify for 2.5 hours, the taking photos and sending them, yt on wifi at home. Most pf the time on data
[Samsung Galaxy S9+ Real Life Review] mtm1401:
I don't understand how they can be so different
[Samsung Galaxy S9+ Real Life Review] IUH1991:
My Canadian s9+ came in yesterday. Currently on its first battery cycle. Have everything enabled: aod; location; auto brightness; etc.

My s6 would have been dead by now!
[Samsung Galaxy S9+ Real Life Review] jasonx3:
I'm on exynos version and max SOT i can get is 4 hours. screen resolution on FHD+ really disappointing. I'm coming from a oneplus 5 and i reached 6 hours of SOT with same usage.

I did noticed that when phone is idle and sitting on a desk battery drain is 1% for 2-3 hours but once i turned it on battery dropping faster. i mean way faster
[Samsung Galaxy S9+ Real Life Review] madnav:
BT and Held awake times seem to be the causing excess drain.

Nonetheless, the one with 16% remaining seems good enough; while the other one with 50% remaining looks excellent.
[Samsung Galaxy S9+ Real Life Review] turtuv:
I started to use AccuBattery app, but i don't see "Android System" anywhere in the consume of the apps...how is it possible?
[Samsung Galaxy S9+ Real Life Review] mtm1401:
Accubattery doesn't show system apps/ processes but is good for isolating screen on / off drain etc. Download GSAM and enable the full set of permissions with adb - https://android.gadgethacks.com/how...-monitor-battery-life-cpu-usage-more-0176857/
[Samsung Galaxy S9+ Real Life Review] turtuv:
I don't want to use adb. Is there any other apps which I can use?

[Samsung Galaxy S9+ Real Life Review] mtm1401:
Unfortunately not, since android 7.0, usage statistics are blocked by default, it's honestly not that difficult to do if you get half an hour, also doesn't impact your warranty etc.
[Samsung Galaxy S9+ Real Life Review] mtm1401:
Mobile data vs Wi-Fi (exynos)

How is possibile that the total time of use is exactly the same to the standby time? Anyway 2h sot..very poor performance

I think the usage is around 2 - 3 % per hour with AOD
[Samsung Galaxy S9+ Real Life Review] jdawg334:
Unplugged 32 hours with I'd say average use with phone calls, texting, email, couple games of pubg and HQ. My moto z never lasted this long so I'm cool with it.
[Samsung Galaxy S9+ Real Life Review] md310:
14%, 13h 11m unplugged, 6h 55m SOT. ****ing fantastic compared to my Note 5 from day 1.
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
4 to 5 hrs SOT even after disabling several apps is what I get from the S9 plus(Exynos). OP5T I have and with more apps installed and not disabling anything, it's endurance is twice of the S9 plus(with bloats disabled).
[Samsung Galaxy S9+ Real Life Review] jasonx3:
having to charge twice a day driving me crazy. should've bought something else and read the reviews properly
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
I have been thoroughly in search of that "something else" clicking all the right boxes, just not getting one.

---------- Post added at 02:03 PM ---------- Previous post was at 01:52 PM ----------

Exynos or SD? Single sim or dual sim? In a thread some1 said single or dual- doesn't make any difference but used with one sim and it gave some 3 hours more battery life in standby and about an hour or little more in SOT.

Even with most bloats disabled I just can't cross 5 hrs of SOT(about 14 HR total runtime) and get about 7 hrs of SOT when using like a "dumb phone"(aod off, FHD+ res, only on mobile data or wifi, smart stay off, sync off, all bloats disabled.... and many more) with a single sim(about 17 HR runtime).
[Samsung Galaxy S9+ Real Life Review] md310:
SD
[Samsung Galaxy S9+ Real Life Review] maximus81:
I get around 5 hours SOT on my S9+. however it varies from 3.5 to 5.5. Just my 2 cents worth--- SOT depends on the brightness level of the screen and also if you are on 720p, 1080p or quad. imagine running on 720p and using your phone indoors. Brightness level will be around 30-40% and you will probably get 6+ hours of SOT. on the other hand running 1080p or quad resolution outdoors where screen brightness is 100% you will probably get around 3 hours. Yes, to some extent some rogue apps can cause battery drain but screen is biggest user of battery. So its very subjective. If some users are getting 6 hours SOT and you are getting 4. don't worry, it doesn't mean your phone is faulty.
[Samsung Galaxy S9+ Real Life Review] IUH1991:
I find that the more you use your phone during the day, the more sot you'll have. If you use your phone sparingly, sot will be reduced because of drain while using.

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), YouTube was mostly 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.

Mine is so bad. I don't know why I am always on wifi
[Samsung Galaxy S9+ Real Life Review] linom:
Sammy phones are overall good packages but very poor in standby/endurance. I am an S8 users searching for that solution which will help me increase the standby time. Realized its the elusive tooth fairy that we've been looking for. Samsung phones are a hit or a miss in terms of s/w optimization in relation to hardware. The same exact phones will vary wildly in their endurance performance given all other conditions are same. Folks like us have spent countless hours on tweaking and optimization & searching for solutions without much success. Unless Samsung improves its s/w, especially in 2018/19, it will surely become the next Nokia or HTC.
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
This looks indeed good.

On a side note, I got about 7 hrs sot with one simcard+ bloats disabled+ dark theme+tweaks & 5 hrs with 2 sims.
[Samsung Galaxy S9+ Real Life Review] bassgenerator:
I'm sorry but for a long time I did not read such a stupid post on the forum ... you can not say about Samsung because sales and numbers always say the most.

Samsung, on the contrary, always represents minimal evolutionary devices in the field of telephony and media and allows to say that it always goes with time. welcome a friend on earth.
[Samsung Galaxy S9+ Real Life Review] linom:
I am not sure what's stupid about this. I am stating the obvious what most of us experience. No one wants to spend hours figuring out how to reduce battery drain. And that's what is exactly happening to many Sammy users. Nokia numbers also spoke for themselves in the last decade. I never meant Samsung is boring, but if it doesn't provide a complete experience, then it sure is going to face a tough task in the future to survive in the handset segment.

Nothing impressive, as

1. In both cases the total runtime is below 10 hrs. It matters a lot.

2. Single sim.
[Samsung Galaxy S9+ Real Life Review] marsen2567:
Impressive SOT! My most time I had with it, was 8 hrs and 40 minutes. Nice!
[Samsung Galaxy S9+ Real Life Review] Encik Panda:
Thats because i've used my device for endurance as soon as it full charged. Im using it straighted from 100% to 10% nonstop :fingers-crossed:

---------- Post added at 03:58 PM ---------- Previous post was at 03:53 PM ----------

Thanks mate ! You should get better SOT if you put all your apps except important apps like WhatsApp/Telegram always put to sleep and optimze ur device regulary. Because thats what im doing.
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
8,9 hrs SOT I too get with a total runtime of around 9, 10 hours.

But.... get 5 hours SoT with about 14 hrs total runtime and around 4 hrs SOT with about 16,17 hrs runtime with few "tweaks" in all these scenarios.

Thats not good battery endurance in any of the cases. :mad:

Tmobile snapdragon. Normal day

Package disabler around 180 app/resources disable

AOD on 24/7

HIGH PERFORMANCE ON and QHD.

I didnt even notice my battery life until i saw this thread and went to check mine and to my surprise on a normal day of use this is what im getting

It's spot on. SD is far superior in terms of performance and battery life this time around. U guys r lucky.
[Samsung Galaxy S9+ Real Life Review] marsen2567:
That's the usual average I get too. but with WQHD and usually entertainment performance mode on and scheduled AOD. The battery life for me is amazing.

Nope, I mean my longest SOT gets to 8 hrs and 45 minutes but it can last a whole day at school. Usually 1 and a half day. I've already disabled bunch of stuff, way before. :good:

Maybe longer this time, I just got an update, today. I think it was just a security patch though... with stability update..
