Probably my final screenshot - this is with periods of light-moderate use over quite a long time on battery. Again, you can see how AOD uses a significant amount of battery over such long periods. Can't complain.
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
OnePlus 5T, pixel 2 xl, iPhone 8 plus, oneplus 6, galaxy note 8, galaxy s9 plus snapdragon, Huawei p20 pro... These all have, had good batterylife imo.

S7 edge from 2016 was having one of the best batterylife during that time and was giving more endurance than the predecessors like S6 edge+, S6 edge etc. Even then, there were flagships with better batterylife. This year the s9 duos(exynos) provide lower batterylife than the predecessors like note 8, s8 plus as per reknown reviewers and as per my own experience.

---------- Post added at 04:37 AM ---------- Previous post was at 04:24 AM ----------

Below is my s7 edge from 2016, I used it for about 2 years, the longest period I've ever used a smartphone - for one simple reason - it's batterylife. When new it was giving 6 hours and little more of SOT with a total runtime of about 18 hours and with medium to high usage-something I was so happy about, and yeah it was a dual sim version with ZERO tweaking:)
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
Sad to see in 12 months it was rocking so low batterylife in your case, seems like your battery charging wasn't ideal. :)

[Samsung Galaxy S9+ Real Life Review] ssj100:
Just out of curiosity, how many hours SOT were you getting when your S7 Edge was brand new? You mentioned that you were down to 1.5 hours now, and that you'd be "happy" with 3-4 hours. We already see even the people here who are unhappy with the battery life of the S9+ report 3-5 hours SOT, so I think you should be somewhat satisfied with it. And as I reported, including myself, there are several people in this forum who don't do any significant tweaking and get much more than 3-5 hours SOT with light-moderate use.
[Samsung Galaxy S9+ Real Life Review] Yiayiah:
Not loving what i have here...

I got my S9+ three days ago and the battery is horrible.

AOD is off and i found the battery drain faster when i use google chrome. Left home at 7 in the morning with 98% and came back at 11 before noon and the battery was already lower than 60%.

Last night i charged my phone to 100% and turned on airplane mode and went to bed. 7 hrs later i woke up with 90% battery.

W T F

*I have no idea how to upload images here :(
[Samsung Galaxy S9+ Real Life Review] Galaxo60:
Honestly I don't know what you guys do with the phone, even with heavy gaming, I can achieve more than 5 hrs SOT over a day.

This is from now:

:confused:
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
Chrome indeed sucks more battery. Samsung browser in better in a Samsung phone.

..

Your condition is absolutely unacceptable. Assuming that you haven't factory resetted the phone yet, do not live in a very low signal area and assuming that you messed up with the phone setup and apps , go for a factory reset immediately. Doing so, your condition will certainly improve a lot.

But , do not expect very good batterylife out of it unless Samsung pushes a kernel overhaul in the Exynos variant in future. Cheers :good:
[Samsung Galaxy S9+ Real Life Review] Yiayiah:
Should I charge my phone back to 100% before doing the hard factory reset? It's really disappointing since this is my first Samsung phone.

I left home today at 11 am with 100% and went to gym with my Spotify playing for half an hour. Came back home around 7 pm and the battery was lower than 35%. The total SOT I had today was around 3 hrs. It does suck since my last phone was Sony Z2 and even that ****ty old phone was better than this :(
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
Not required, just 40-50 % are enough.

..

I used the Xperia z2 too, batterylife wasn't great in it either. But now u r in the land of Samsung UI that's sometimes more problematic than any help who aren't familiar with...

I do understand ur pain. Post factory resetting and setting up the phone with all your required apps downloaded, installed and setting them up, disable uninstallable apps that you do not use(carrier bloats and Samsung's own bloats), keep unnecessarily syncing off in your accounts and apps as per your liking. Post this, play around with the settings and u would come across various battery friendly options.
[Samsung Galaxy S9+ Real Life Review] ssj100:
Well some here would say that you just have to accept that the battery life is horrible and that you are actually "tweaking" the phone already to try to get good battery life (eg. "AOD is off"). Interestingly, despite this "tweaking", your battery life is actually much worse than those people who claim/imply that they haven't tweaked anything and complain that the SOT is only 3-5 hours over around 10 hours on battery.

Your standby drain doesn't sound right, especially with airplane mode AND Always On Display off - it looks like you lost >1% per hour, when it should only be 0.5% or less. I only lose ~1% per hour with AOD on (and no airplane mode), and I've seen most people who report this have similar experiences. So there's perhaps something draining your battery more than it should even in standby.

Can you describe how you're using your phone? What apps did you use between 7am and 11am that could have drained the battery from 98% to <60%? In my experience, to lose around 10% or more per hour almost universally requires doing something heavy like gaming or GPS navigation with High accuracy.

Yes, it took me a while to figure out how to upload images here too! One way is to either click on "Post Reply" or "Go Advanced" and then click on the "Attachments" (paperclip) button - I've attached pictures to hopefully help.

Finally, some people have noticed that it takes Samsung phones a few days to "settle in" - perhaps you'll find the battery life spontaneously improves a lot after a few more days? If not, I'd agree with trying a factory reset and manually installing your apps from scratch if it's not too much of a pain (again, I've seen many people reporting that this improves battery life a lot).
[Samsung Galaxy S9+ Real Life Review] Yiayiah:
Between 7 and 11 am, all I did was using Google Chrome, Spotify, Line, Instagram. I didn't use GPS and play games at that time.

*I'm using the XDA app but still can't upload photos
[Samsung Galaxy S9+ Real Life Review] Th3Bill:
I want to love this phone SO badly, but the battery is just so middling in its performance. Wholly inconsistent. One day, I'll use the phone like crazy and get 4+hr SOT and go to bed after 17 hours off charger with 35+%, then comes days like today, where I'm not even at 2.5hr SOT, have used it less than most days and the phone is at 14%.

Audio and Camera on this are beastly, but frankly, the battery makes me really concerned about whatever is going on with the software.

Even on it's best day, it's still easily the worst battery life of any phone I've had in the last 12 months, and I've had the S8, Z2 Force (best battery but worst camera made it useless to me, but avg 8hr SOT), iPhone 8 Plus, LG V30, Note 8, iPhone X, and now this.

Disappointing, as it's such a slick phone otherwise...
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
Totally agree with you. Inconsistent batterylife & unpredictable at the performance level when you compare it to flagships of the last one year. Issue is in the software and kernel level@exynos.
[Samsung Galaxy S9+ Real Life Review] Galaxo60:
Exynos or Snapdragon?.

:confused:
[Samsung Galaxy S9+ Real Life Review] itstock:
snapdragon and exynos both have samsung ui - never known for best optimization.
[Samsung Galaxy S9+ Real Life Review] ssj100:
Well his profile has stuff like the USA flag and "T-Mobile", so I would have thought it's Snapdragon. If so, you know exactly what I'm thinking hehe.
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
Right, and so?? I'm concerned about the Exynos more as Samsung is experimenting with new ARM cores with bigger die size UNLIKE the last few years.

---------- Post added at 10:00 AM ---------- Previous post was at 09:56 AM ----------

FYI, carriers have their own optimizations above the OEMs.
[Samsung Galaxy S9+ Real Life Review] itstock:
die?:eek:
[Samsung Galaxy S9+ Real Life Review] vulgaros:
You have snapdragon
[Samsung Galaxy S9+ Real Life Review] viper31573:
Is that generally better battery wise than exnyos?
[Samsung Galaxy S9+ Real Life Review] vulgaros:
0

Judging by my own experience with the Exynos S9+, with similar settings like other users with the Snapdragon variant (highest resolution, AOD off, 4G/LTE on), I would say the two variants are suprisingly evenly matched as far as battery life is considered.

Please take a look at my phones consumption and compare it to that of users with the snapdragon, its roughly the same.

Needless to say, so far the exynos s9+ battery life has been good to me and I am happy with it.
[Samsung Galaxy S9+ Real Life Review] GodXen:
Isn't the best results, but I hope it's gonna be enough for a full day.
[Samsung Galaxy S9+ Real Life Review] lunzi88:
I'm really happy with the battery life on mine.

Especially this cycle which seems to be completely insane.

Exynos, running on WQHD, No AOD, SABS installed but no bloat disabled.

I'll say 60/40 for wifi/4g
[Samsung Galaxy S9+ Real Life Review] GodXen:
I wonder what you was doing, only watching at home screen? 37% battery usage goes for screen in your screenshot. In my screenshot for example 24%. Probably you have no Apps that runs in background or something.
[Samsung Galaxy S9+ Real Life Review] lunzi88:
I doubt anyone could just stare at their homescreen for over 8hrs, usage wise basically was just couple of hours for web browsing+YouTube and also reading of ebooks low power apps basically
[Samsung Galaxy S9+ Real Life Review] bassgenerator:
So the third charging cycle. I am satisfied. Exynos S9 +
[Samsung Galaxy S9+ Real Life Review] Cristi10:
Two different days, using navigation a lot on 4g( the waze app and g mapps). Pretty satisfied, if they would make the stand by drain on data better it would be a beast. I use wifi at home and leave the data open throughout the day all the time when i am out. Idk how it compares with the pixel 2 xl. It was between these two, but i opted for the s9+ because in my country pixel is still expensive (we don't have google store), it's like 1000€ while i got the s9+ with about 600.
[Samsung Galaxy S9+ Real Life Review] GodXen:
Seems like chrome is using way more battery than that Samsung browser.

[Samsung Galaxy S9+ Real Life Review] xnostra:

[Samsung Galaxy S9+ Real Life Review] Venom0642:
Ok thought so there's lots of reports on Exynos and unlocked phones for S9 Plus and S9 are getting lots of battery drain i read and seen it on YouTube and over the website , seems about 90% of the people have this drain problem. And Snapdragon has no issues on battery drain just letting you know what's going . So basically it's and issue with Exynos and unlocked phones.
[Samsung Galaxy S9+ Real Life Review] GodXen:
Thank you for the information. And yes my phone is unlocked
[Samsung Galaxy S9+ Real Life Review] skivnit:
Where did you read that? You can check on exynos battery thread and on reddit most are happy with their battery life...

[Samsung Galaxy S9+ Real Life Review] Galaxo60:
I saw his profile too, but I still wanted to ask to be sure; and yes, I think we are thinking the same.

Anyway, people think that "carriers have their own optimizations", when the only thing they do is put a lot of apps and sometimes a couple of options more for specific services.

;)
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
That includes optimizations and security patches throughout the board, like AT & T providing battery optimizations, krack wifi and blueborne exploits to galaxy note 8, like T-Mobile providing carrier update to galaxy s9 for camera stability.

In the process, sometimes it works not as intended like any other carrier. But in no way it can be mixed with what the OEM (Samsung here) alone has done with the gadget, the unlocked ones.

Look, u maynot hit the reply button, but even a noob would understand whom u intend that msg to and I'll respond with relevance as long as I find ur msg misinformative and worth responding to.
[Samsung Galaxy S9+ Real Life Review] ssj100:
Yes for sure. I think I mentioned previously that I always "factory reset" all my devices (not just smartphones) like laptops and desktops, but that's not actually true - for laptops and desktops, I actually completely format all hard drives and re-install the OS from base. One of the reasons for doing this is to completely get rid of this "carrier rubbish" hehe. For smartphones, I'm not "brave" enough to do that yet!

And yes, definitely thinking the same hehe.
[Samsung Galaxy S9+ Real Life Review] Th3Bill:
SD T-Mobile variant.
[Samsung Galaxy S9+ Real Life Review] Galaxo60:
Thanks for the confirmation, because some people is arguing that poor battery is only in Exynos models and Snapdragon models have good battery all of them.

For me, I think is a mix of configuration, apps, usage, location and signal strength.

:laugh:
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
Thanks for letting us know that u r using a T-Mobile locked version.

Hope u tune ur phone to get carrier bloats removed without compromising anything on the standard features like many Exynos users here, as technically, u r using the superior version of the s9+ in terms of batterylife, performance and heat management.:good:
[Samsung Galaxy S9+ Real Life Review] Th3Bill:
I have to laugh, as I've used a ton of devices and can't remember a recent one that seems to be this inconsistent despite having everything set up exactly the same. Weird...
[Samsung Galaxy S9+ Real Life Review] ssj100:
A YouTube reviewer (I can't recall which one now) also mentioned something about the variable and "inconsistent" battery life on the S9 in his experience. He was also using Snapdragon I think, so you're not alone. I hope you manage to improve things. I'm just grateful SOT/battery life isn't one of my issues - I just got nearly 5 hours SOT with 15% still left and just under 33 hours on battery. No tweaking required here, even AOD is enabled (and again, used up a chunk of my battery!).
[Samsung Galaxy S9+ Real Life Review] Th3Bill:
Oh wow....so if the SD variant is the superior battery life one, I guess I'm glad I don't have the Exynos, as I didn't think less than 3hr SOT over 17hr to be superior to much...

Now that I've said this, I'll go to the same places today and battery life will be totally different LOL

---------- Post added at 07:09 AM ---------- Previous post was at 07:07 AM ----------

I've had a couple of days here and there with similar good battery with it...just have had a lot of em with really oddly low battery life as well...
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
Lol, correct. What do I say, Anandtech, geekyranjit, android central, strategy analytics, imore,BGR, techradar, trustedreviews, androidpit, phonearena, all say that Exynos variant is having a much poorer and inconsistent batterylife than the Snapdragon variants this time around and the schedutil governor is taking a toll on the SoC affecting performance and heat management as well. I have to agree with them as I've tested two galaxy s9 plus exynos only to bow down on what those reviewers exactly said. And I have to say, like you I keep using a bunch of phones and the Exynos variant is top from bottom@batterylife in comparison to atleast 5 other top tier smartphones I've tested in the last one yr or so and I used all Samsung galaxies(non-notes) in the past.

[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
BRE5 firmware is having a kernel version number change. Flashing it now and will see if at all the firmware did anything apart from black crush/color banding. Users say it made the phone snappier. :)
[Samsung Galaxy S9+ Real Life Review] :
I highly suggest disabling apps that you don't use, specifically Samsung apps.

For instance, some Samsung apps can be uninstalled, some can be disabled, and for those that can't be disabled, use ADB shell without root.

Just use "adb shell pm list packages | grep 'keyword' " to list and "adb shell pm uninstall -k --user 0 com.package.name" to disable system apps forcibly. Now remember to uninstall their updates if they have any.

If you go into settings it will mark them as "Not Installed" but they are still loaded onto your system since /system is read-only.

So basically the effect is just like disabling them. I've disabled all Bixby services using this method and some other samsung apps, also the gear services and google vr services.

I also use Greenify's aggresive doze.

All of these helped me squeeze out a little bit more juice on my S9+, but not by that much. Still, I can almost get through a day.
[Samsung Galaxy S9+ Real Life Review] ssj100:
How sad that some people resort to a mocking/bullying way of posting to each other - I hope they don't talk like that face to face to people in real life that they barely know! At first I thought I'd go on a hunt and post links of the videos that reported the Snapdragon having "disappointing" or "bad" battery life (I did find at least two on YouTube by the way, and funnily enough, there were several associated comments mentioning that they are really happy with their Exynos versions and getting 6-9 hours SOT etc), but then I realised it's not going to help address this bully and how he writes here (probably only make things worse). And I've already wasted enough time with this bully. The way he reacts to this post will likely back this comment up, although I hope we can all settle down and go back to the pleasant atmosphere that Galaxo60 mentioned in an earlier post. Even if one thinks another is wrong, we are taught as kids to write/speak charitably to each other. We are also taught as kids to ignore bullies and here's a good article on it hehe:

https://www.wikihow.com/Ignore-a-Verbal-Bully

Anyway, back on topic, do you think your variable battery life is due to using Wi-Fi verses Mobile data? Just throwing it out there, as I certainly noticed battery draining faster when I was using roaming Mobile data. However, I was still able to achieve around 5-6 hours SOT, so your "less than 3 hours" SOT is indeed disappointing. I note that the latest May Security update seems to address the "black crush" (I was corrected recently that it should actually be called "banding") issue, so perhaps it also helps with your battery issues. I'm just hoping any update doesn't interfere with my own battery behaviour, as it's excellent as it is!

---------- Post added at 10:28 PM ---------- Previous post was at 10:23 PM ----------

Just out of curiosity, are you referring to the Exynos or Snapdragon version? And with all these tweaks, what's your SOT verses without these tweaks?
[Samsung Galaxy S9+ Real Life Review] shaggyskunk:
You probably can't upload photos because you don't have enough posts to your name (I believe that 10 posts minimum are required) Don't post nonsense to get to 10 posts or you may find that you get some grief from the Mods! ?
[Samsung Galaxy S9+ Real Life Review] Th3Bill:
I get that we can eek out extra minutes out of a device by disabling stuff and doing all sorts of wacky workarounds, etc. That being said, when one pays 900 bucks for a phone, one should expect it to be able to get decent battery life with consistency without some heroic effort. I consider decent on a 900 dollar device to be 4.5-5hr SOT minimum without monkeying around with it.

I blame Samsung and their lack of prompt updates and insistence on focusing on the "next big thing" they plan to release instead of updating their newly released phones for these issues.

On top of that, they lock down the device to where good dev's can't work their magic on the device and make it a consistent killer like phones of yesteryear used to be.

I love the device, but I'll be honest that I'm looking forward to the next big phone to come out on T-Mobile...
[Samsung Galaxy S9+ Real Life Review] shaggyskunk:
Yeah I agree with pretty much everything you said regarding Samsung's eagerness to forget the current Flagship & concern themselves with what's next - The other thing to consider is it's not Samsung but the Carriers who really bear most of the responsibilities for Battery draining Bloat (there were some apps that could effectively disable System apps [most of the Bloat is baked into the devices as System apps] Unfortunately Samsung took an aggressive stance and they've been removed from the Play Store & XDA Threads were locked & links removed - ie: BK Disabler/Manager - SABS - Adhell 2 etc).

Regarding Locked Bootloaders - Samsung is only doing what the Carriers requested & the Carriers are Samsung's biggest customers... It all started with AT&T...

But imagine if you couldn't get Administrator rights to your Windows computer.... That's effectively what has happened with Locked Bootloaders & it's because we don't buy our computers from a Carrier... ?
