For all you guys who need the edge on battery, and dont need alot of screen brightness, like me, then try out this app on the play store called screen filter. (I am not affiliated with this in any way, I just like the way it works). What it does is apply a "film" over your screen going even lower than android screen brightness. Perfect for office setting (like me), at night when brightness is too much (laying in bed playing a game), or where bright lights might not be wanted (movie theater, work, etc...). I personally love it, I use it usually at 75% with the android brightness off, and everything is still visible, just that extra kick of brightness is gone. Sometimes I go down to 50%, but that gets me seeing my reflection just as well as the screen itself...
It also helps to keep out them creepers that try to look at your screen while sending private texts, pics, etc... Helps keep wandering eyes off of the fancy 4.8 super AMOLED display!
You can add widgets to custom brightness settings to suit yourself, I have 4 right on one of my screens that I use frequently!
I recommend this app to anyone and everyone!
It wont let me post links, but if you search "screen filter" it should be the first app. The logo has a white rectangle outlined in orange with a grey circle in the corner. Not too hard to find at all.
I'm almost positive that screen filter won't increase battery life. I think the phone basically "thinks" its still at a higher brightness than what you see, so it really doesn't improve battery life. I may be wrong though but I remember seeing that when I used it on my droid x.

OLED pixels produce their own light (that is, without a separate backlight). Colors are made darker by dimming pixels. If the app makes what's being displayed on the screen darker, it should be helping battery life. The same reasoning applies to saving juice with dark backgrounds and inverted apps. It just only works on OLED screens and not backlit screen types.
Okay. I wasn't sure if I remembered correctly. Thanks!

Lux Auto Brightness works a little better, in my opinion. It can go less than the screen's brightness without the filter look.
Hi guys,
A friends uses auto brightness, and only speaks ~ 20 minutes / day. A few browsing, reading e-mails, games, just got him at 2 days of usage. Not bad in my oppinion, but certainly they should have improved the battery.
To me it seems like the battery life is longer. My first week of use around 9 or so it would be in the red, but using it throughout the day, at 9 tonight it sits at 37%. Yes it will vary depending on use, but mine has been on battery 15h 30m and screen is only 18%. Cell standby is 30%, and chrome and facebook are each 11%. Everything else is quite small compared to those main apps used.
It seems to me it is helping, but it may not idk. I will continue to use it unless I run into a major issue with it.

+1 to Lux. Set your own brightness levels for various light levels. It can make the brightness very low, almost not visible.

I would be happy to get 2 days of usage... I probably could get 1 and a quarter, but I charge mine every night to be safe. Really varies on how much I use it during the day. Some nights I plug it in with 10% others with 50%... I know its not the best for the battery, but I just plan on getting a new one when this one takes a crap. I have a feeling this phone will be around long enough that the option will still be available

What I would like is for my battery to last just *ONE* day. It doesn't do that. I don't mind charging it every night, but I'd prefer it last the day without me having to either charge it or switch batteries.

nice find
nice find on this. i use inverted apps, and i like the way this works
What is everyone thinking about the always on display? Will you be using it knowing that it costs 15% battery per day? Tbh, that sounds really high to me to light up such a small amount of the screen but I guess I don't know really

Where did you read that it's going to use as much as 15% battery per day? That sounds quite ridiculous given the fact that LG stated that their Always on Display implementation drains 0.8% per hour. Which is around 19% per day (24h - day and night), but the G5 uses IPS panel. There's no way if an LCD is using 19% per day an OLED screens showing primarily black to be draining 15% a day...
What you need to factor in before you start saying how high battery usage is...... How many times per day do you check your phone for notifications etc??? If you are constantly checking for texts / Facebook updates or whatever then AOS is for you. Whilst it may use X amount extra per day of battery if uses LESS power than powering on the whole screen and taking the device out of idle to check if you have any missed calls etc. If you are one of these people you are better off using AOS.

Samsung said 1%/hour. Also, LG made some adjustments to be amoled-like: “To minimise power consumption,” said LG, “we redesigned the display driver IC memory and power management function so that the display’s backlight only illuminates one small part of the overall display. Thanks to this technology, the Always-on Display requires only 0.8 percent of the battery’s full capacity per hour to operate. With consumers turning on their smartphones up to 150 times a day mostly to just check the time, the G5’s Always-on Display will make a notable difference in the life of the battery over the course of the day.”

You also have to keep in mind that when it is face down or the screen is covered the screen is off until you turn it over or take it out of your pocket or purse.

LG said their always on display uses 0.8% per hour and it's an LCD, so how does it make sense that an AMOLED display would use more power? LG only lights up a third of the display for it to save power compared to a regular LCD, but that should still use a lot more power than lighting up just the pixels necessary. Frankly, I trust Android Central on this more than any other site. They got behind the scenes time with Samsung at MWC and they are typically very reliable. The sites I see reporting 1% per hour (phonearena, Android Authority, etc.) are sites that I find very unreliable as I spot mistakes in their articles and videos all the time. Just one site probably got it wrong and then every other site copied them on the wrong info.
Here's another source that says 1% per day, so it's not just Android Central. And I know I heard it from a third source too before Android Central even wrote about it, but I can't find that now.
https://youtu.be/JtPBBil56a8
Edit:
Here's another source: http://www.uswitch.com/mobiles/features/samsung-galaxy-s7-always-on-display-faq/
Anyways, I guess we will know for sure when a lot of people start getting the phone. I will test it and will definitely turn it off if I find that it is using 16-20% of the battery in a day, but I really doubt it will use that much.
i think its going to be closer to the 1% per day because if you look at the s5's untra batter saver mode they have proven by reducing what the display has to show and reducing the processor power they can make the phone last a hell of a lot longer on the same charge
LG has an IPS display, Samsung has SAMOLED.
Samsung said that it should save battery because you only check the notofocations on the screen and didn't need to turn it on.
I'm not scarried from battery but from burning the display.

Worried about screen burn-in? Samsung has thought of this, too. Though the information displayed looks to often be a static image, the software is actually regularly shifting the pixels ever-so-slightly so that the same ones aren't used over and over again. This eliminates worry about those pixels "burning in" the lock screen image, and it's one you won't even notice happening. The phone also won't display the information when it detects it's in a pocket or a bag, and if you just don't like the feature you can always turn it off completely
That is a quote from the android central

does anyone know what triggers the always on display to be dim some times and bright the next? i've been trying to find a cause and i dont see any. it will be dim one minute and just become bright for no reason it seems. this is with a black background and unplugged from the charger. i would like for it to stay dim to use even less battery.
Turned it off 2nd day. Uses too much battery. I only turn it on for when connecting to charger. It's definitely near 1% per hour. I Just have the lock screen wallpaper completely black so it doesn't drain batt just to see time.
Plus always on display is pointless when it doest tell me anything more than time.

Mine does the same, i'm guessing it's designed that way to keep any sort of "burn in" or similar from happening after long term.

Maybe it's pointless to you, but I use it a lot just for the time. If your's is using close to 1% per hour, I suggest you get your phone replaced.
the always on display is definitely eating up around 1% battery an hour on my phone. this is with most of the bloatware disabled. i can look at my battery every hour and it will be down 1% some times 2%. i tested this with turning always display off for a couple hours and not turning my screen on and after 3 hours i lost 1% battery. i'm thinking it has something to do with the always on display becoming too bright at times and i dont know how to get it to stay dim.
Always on seems to turn off in pocket but not in the night. Is possible turt it in the dark and in the night automatically?
I've just bought my phone two days ago, but it seems to have a really awful problem, my battery is draining like hell, I don't get more than 7 hours SOT and sometimes my SOTs are aweful.
Take a look at the screenshots.
Is it normal? Tell me if it isn't so that I can take it for a replacement.
One of the screenshots are from 100 percent to 14 and the other one is from 100 percent to 79
Also my phone is always warm and I think that it's too much warm sometimes.

If your phone is quite new , then I'd suggest that you should most probably put your phone through many charge discharge cycles . if the problem still persists then I'd really advice you to take a replacement

7 hours SOT is good. You have no reason to complain about that.
Also, you need to wait a week for everything to settle, and let the Samsung power monitor start putting unused apps to sleep.
Also, dual SIM phones will use more battery than single SIM.

@JohnSmit268 I have a Dual SIM S8+ as well, only use it with 1 SIM, but I get about the same battery life as you do, slightly better but I'm happy with it. I've put some apps to sleep permanently so they don't run in the background and I use it at about 30% brightness.

I noticed your computed power usage with 7h SOT was 1633 mAh, that's a lot higher than mine.
With 30% brightness, full res display, and a black theme, my computed power usage with around 7 and a half hours of SOT is only around 800 mAh.
Do you use AOD?

Difference between FHD and WQHD+ is negligible and makes almost no difference to battery usage.
If you think 7 hours SOT is not good, then you are honestly very much mistaken. It is very good.
But you simply cannot compare easily with someone else. There are so many factors that change. Signal strength, wifi strength, how often you use wifi and data, brightness, auto brightness, AOD, vibration, sound, bluetooth, NFC, apps installed, apps used, apps running in the background, location settings. They all make a difference and vary between every device.
Colour of wallpaper will make a big difference too. Wallpaper with lots of black will save power because of how AMOLED displays work, so that will also makes a difference between every device too.

Don't know if it's luck or something, or maybe it's a one time happening but this is my test result, with the draining speed I have, it can give me around 9 to 10 hours SOT. I had the 3G always on, my brightness was more than half. This SOT is outstanding, I wish my device maintain this. I turned off AOD, switched to a black theme and used full res display.
Just wondering why the screen usage is that high. 2400 mAh...
So I want to know if you all have similar experiences..
I have Galaxy S9+ 128 GB Exynos Version - ALL STOCK
The screen on continuous use battery consumption is very good... it drains 13.5-14.5% per hour at max with location, 4G on.... Which means it can get to around 7 Hrs of Screen-on time easily.... even more if we use low powered media apps like youtube, netflix etc....
However, the screen off battery drain is relatively high...
A standard day has around 10-12 hours of standby time when you are out and moving with 4G on all the time and 1-2 hours of music... and in that time the might drain up to 35%+.... Limiting the screen-on time to around 4:30 hours... The deep sleep percentage of the total screen off time is around 65% which is no so great....
This is without using Power saving modes...
So the battery life gets around 7/10 for me.... It is good enough and for 90% of the days it will last the full day.... just not as comfortably as I might have hoped..
On my Galaxy S6 I used apps like Forcedoze, turned off sync, location, 4G, haptic feedback, unused apps, and I could squeeze livable battery life out of it... I am sure that if I did the same with the S9 the phone would have 2 day battery life.... but the out of the box battery life of the phone is average...
So I recommend turning off 4G when not in use and use Power saving mode once you hit 35%.... this way you can easily get through the longest days on a single charge....
The phone needs improvement to its stand by time....

I think that a lot has been said about this topic, and in the end, the user is the only one to blame for the battery life, because there are a lot of things that can impact battery: location, apps, usage, signal, etc.
Is hard to do an objective and good analysis of battery life, because each user will put their own subjective thoughts. For me battery can be great, and for others can be awful.
Is true that 4G will consume more battery, but only if you are in an area when signal is weak, otherwise, in most cases it will have the same drain or even less, because with faster speed, the modem works less and the impact is less as well in battery.
Power saving mode is going to save you some juice in case you cap all the options to the minimum, but honestly, who wants to run an S9+ with an HD resolution?, and the brightness and CPU cap don't give you much more battery either, and I found it stops the sync of some apps, but not others.
I think that the only real way to improve your battery is to properly configure your device, set the proper permissions for every setting and app, and then use the "Energy Monitor" built in app to let which apps can be running in background and which don't. Doing this will improve battery by miles.

The whole thing has to be intuitive though... having to tweak 200 settings in the phone to get better experience is not part of the experience... experience is the stock default usage with some minimal tweaking... This is the reliable battery life I can get without breaking any service in the phone because I might have to analyze the effects of every option I change or turn off..

Is partially true what you say: if you get a Samsung, is because you know you will have all those options and most probably you will have to make the proper changes. We all know that Samsung phones usually offer ton of features and options, but if you don't configure them, probably they will mess a little the battery because most of them will come enabled and will have an impact in battery life.
On the other hand, if you want just the basics and a simple experience, you should stick with Android stock or closer.

They forget to tell you that is more than likely at the lowest resolution, with the screen brightness turned all the way down, with the device in airplane mode.
I don't think this phone will get anywhere near those battery hours. I also think we should expect at least 1 full day of HEAVY use. This is a flagship phone.
Now... All said and done... I get decent battery life, I cant complain. However, I do think it should get better battery life. This cost as much as my Dell Gaming Laptop.

Just disable everything what you don't use and set up the battery monitor for your apps and you will be good.

Well, car manufacturers do the same when they advertised they cars to give 5L/100Km, but we all know that in order to achieve those, you should drive in very specific conditions. The same applies here as well.
And yes, I also have great battery life in my S9+ and I can't complain at all.

These numbers are lab tests under controlled conditions... by no way they represent real life usage...
My S9+ has had an appalling battery life and i have no clue what to do about it.
Apologies for the second post. It was done by mistake and now i can't remove it ...
What is really bad is the network reception.
Most time of the day I have bad or almost no coverage.
No matter what phone I had had they all had average battery life.
So for anyone who has bad battery life take a look at this.
But this is just one cause.
I've got my S9+ for about a week now. Snapdragon version with dual SIM.
So far I finding the battery life a little disappointing. Using betterbatterylife with the ADB commands I getting around 4,5 ~ 5 % / h of very light use (essentially stand by).
I've turned everything off, from Google Assistant to bixby to others Samsung services and still I think it's drainibg too fast.

Can't agree more. Samsung has been consistently misinformative about battery endurance data since the first gen Galaxy S I9000 . "S" series never had good batterylife anyways.(keeping sweet Exynos S7 Edge aside when new).
So I've noticed that my brand new 8T battery life isn't very impressive. I found an article on gsm arena that said there is a bug that causes the device to stay at 120hz all the time when the device is using dark mode. Normally it should clock down the refresh rate when the device isn't being used.
Here is the quote from the article:
Now, let's talk about the refresh rate.
To save power, the display will normally dial back to 60Hz after you stop touching it. It does have its quirks though. If brightness is below 50%, or you have Dark mode ON, it will always keep a 120Hz refresh rate. Yet, some apps like Google Maps, YouTube or fullscreen video playback will always run at 60Hz.

Anyway, I'm just wondering if anyone has noticed this same issue with bad battery and if so are you using dark mode?
UPDATE: I've noticed that the home screen will get stuck at 120hz if you use one of the active wallpapers. I recommend using a static wallpaper to allow the screen to go to 60hz. I've also verified that the settings app in dark mode gets stuck at 120hz. For best battery, set your system dark mode to off. Use a static home screen wallpaper and manually set dark mode for each of the other apps you use daily.
Thanks.
I think they made an error on saying that dark mode keeps 120 all the time. I just used a refresh rate app on dark mode and was able to change from 60 to 120 and it does not stay on 120 in dark mode...so not sure what to tell you???

Thanks for checking. I just took their word for it. I think my problem is that I was assuming the battery would be way better than the Pixel 3 XL I upgraded from but it's just marginally better. I'm just hoping the battery optimization will start doing its thing the longer I use the phone.
It seems there is a mechanism that adjust the refresh rate by regarding a combination of background color and screen brightness.
I have an almost black homescreen, and no matter how high I set the screen brightness, it always stays at 120Hz.
But when using an app with a white background and set the display a little brighter, it switches to 60Hz after a few seconds.

I'm using dark mode from the beginning and tried switching between 120hz and 60hz as I'm not getting that much impressive battery backup. The max i had got was like 6hrs of sot without AOD and ambient display off. Just a normal user. Some casual games, instagram, 90% times on wifi. And yesterday i got like 4hrs of sot at 60hz without AOD but with ambient display notifications on. On the other hand I'm glad we have a 65w which charges the device pretty fast.
I will try the light theme mode and check the battery life and update here.
I think it's forced 120hz unlike Samsung's adaptive. I left the counter enabled from dev options and never see it throttle down unless that's a bug. The description in display settings does say it will switch on its own but I never see that happening. Only time it shows 60hz is when going full screen landscape during videos or certain games that don't support it that's probably what it means by switching dynamically. Could also explain why we get worse battery life than s20fe users who have similar specs but are getting 9hr sot with 120hz. I've checked a few of their screenshots in the sot thread.
Anyone know more about it and can confirm?
@DroidzforLife I am coming from Mi 9T Pro. I had 6-7 hours SOT with my usage (gaming + social media). That was a 60Hz phone. With OP8T, even with a bigger battery, I get around 4 hours of SOT for the same usage. Note that I am constantly in dark mode, and 99% of the apps that I use have dark mode enabled. And it's constantly at 120Hz for me, by enabling the toggle, like @Anon1136 said.
The battery definitely is worse here. The only positive about it is that it charges insanely fast. That's all. My SOT slightly improved to around 5hours by flashing the Radioactive kernel.

Since posting I've switched to system light mode with manually set dark mode in as many apps as possible and the battery seems to have improved but still is not impressive. With my Pixel 3 XL I could get easily 6.5hrs of SOT. I guess we will have to sit back and enjoy our 65w charging for now. I'm just hoping that the adaptive battery stuff will greatly improve the battery life.
Oh and I switched to 60hz/Light Mode and the SOT didn't get much better...

60hz only saved about 10-15% more battery when I tested not really worth it imo. The next update has power consumption and overheat fixes mentioned in the change log so maybe things will be better after. I hope everyone will get that update soon

You mean 11.0.2.3 right? I am on that update. SOT slightly improved. No major changes.

Oh. Well that sucks
My variant didn't get the update yet now I'm not that excited about it lol. Btw does everyone have 5g enabled? It was draining my battery like crazy the first few days now I just leave it on lte. Wanted to share some sot without it but it's not letting me upload for some reason. I can reach 9hr or close to it if I'm mostly on wifi with 120hz all the time, dark mode in most apps except for the ones that mess with text color, 4g, auto brightness around 40-50% light~medium usage as in videos browse text call (anything that isn't gaming or camera). Idle drain is not so great compared to my other phones even with minimal apps installed guessing it will be improved later

When using a dark background you can set brightnes to max and it will stay at 120hz no matter what.
Try a white background and crank the screen brightness all the way up. Refresh rate will switch to 60hz almost instantly.

Just tried that but it stayed 120hz. Could it be because I'm on the t-mobile rom? 11.0.1.3
I had this bug where I would wake my screen and it'd be 60hz but still show 120 for some reason
tried light theme mode and not much change in battery backup

I agree. Disappointing... I went back to fully dark mode @ 120hz because I might as well enjoy what I like while my battery is draining extremely fast right?

Kind of weird sot doesn't change much no matter which refresh rate or theme it's on. I'm getting similar sot on both light theme+120hz and 60hz+dark

True, I had got 6+ hrs once and after that it was like 5 or below. Nothing changed in between
