This is my battery life on s9 plus exynos (non rooted).
[Samsung Galaxy S9+ Questions & Answers] zool84:
Hi,

I was experiencing horrible battery life since i bought my phone in March. Wiped many times didn't resolve so i got used to it.

One month ago i decided to give a try and this time after wiping data and cache i didn't disable any preinstalled application (disabled only LinkedIn and one drive).

Bingo ! No more battery drain and awful battery life, i have an average of 4h sot (sometimes much more) still have more than 30% before going to sleep.

I guess that all my problems came after disabling almost all preinstalled applications especially bibixy.

I hope that this will help, peace.

This is my battery life. All stock.
[Samsung Galaxy S9+ Questions & Answers] GZA1337:
After debloat I get a maximum of 5 hours sot depending on brightness. Which is ok.

Debloat is a must on Samsung phones, that's the only downside...
[Samsung Galaxy S9+ Questions & Answers] crossdeath:
it's definitely not a must, i haven't disabled a single stock app and this is what i get:

[Samsung Galaxy S9+ Questions & Answers] GZA1337:
IF you disable most blaotware you will get better battery life. There are so many stock/bloat apps running in background. Yes, they should all sleep if you do not use them, but do they really? Also they can receive notifications that will wake your phone from deep sleep etc.

Beside of this, I don't like the filled up launcher with apps I never need and also the 'sharing menu' showing lots of crap...

Battery life improved with updates?

Dear community members, I am interested into purchase a regular S9 with the exynos processor (the only variant available in my country ). It cost 560 US dollars. However, I have read that has a poor battery life.

With the latest official samsung updates the battery life has improved?

Or can you please, recommend me a phone with similar or better capabilities (camera, speed, screen) for a similar price?

So those are my stats, got this exynos s9+ since last week, and I think that I'm kinda pleased with the battery life
[Samsung Galaxy S9+ Questions & Answers] Bestmiles:
Thanks, by the way that looks quite good, I guess it will get a similar battery time for the regular s9 (not s9+).

Please, anyone else can confirm that s9 battery is not a issue anymore. I just want to make sure :D ... I have a s4 active with the screen burn, so I think that is time to upgrade a bit. I just want to make sure that I will buy a good phone with my budget.

Guys I have february update, and havent taken another one because I read that battery is not good any more. My question is with latest update has battery got better or still is it worse?

[Samsung Galaxy S9+ Questions & Answers] shaggyskunk:
Probably most people don't even Boot into Recovery after applying any OTA & at least Wipe Cache - Seems to make a positive difference - Staying on the February Security Patch is a risk & for the sake of battery life - it's not worth it in my opinion ?

Guys please download the app Cpuspy plus and check which frequency steps the cpu is using. I found mine doesnt go lower than 748mhz, so thats possible the reason why the phones battery dont last too much. Let me know if it happening also to you guys.

Thanks
[Samsung Galaxy S9+ Questions & Answers] ila420:
This is mine, I don't find it that bad, gives me more than 24 hrs easily. WIFI/4G/Sync/AOD/GPS/ are always on, haven't disabled any bloatware yet, also use live wallpaper and a video wallpaper on lockscreen, I am using this dark theme, may be that is the reason.

Does anyone have a cheat sheet of what bloatware to disable. My phone lasts a day roughly with 4 SOT on average - exynos isn't great
[Samsung Galaxy S9+ Questions & Answers] bsod01:
u can refer to the s8+ bloatware list, its the same

Do u guys think that Samsung is aware of it and fixing the error ??
[Samsung Galaxy S9+ Questions & Answers] srcnDMD:
I also had a very bad battery life with my Exynos S9+, with almost 3-5 hours of continuous use only on a daily basis. I do the same activities I used to do with my old phone (streaming HD videos on Chrome & YouTube + social media like Facebook, Instagram, etc.) and comparing it, it was really disappointing for a very expensive phone. After reading every forum for a possible solution on how to improve it, I decided to do a factory reset earlier today. It's a hassle since I had to reinstall applications, but I thank myself for doing so. I did not disable any apps, I have FHD+ resolution with about 40% brightness but I got a major improvement from how my battery usually lasts before I reset it. I almost came to a decision to return this handset on my network provider, but now I would like to observe if wiping everything off really helped its battery life before doing that.

1:56 a.m. - 8h 48m 22s on battery (5% left)

[Samsung Galaxy S9+ Questions & Answers] Virgo_Guy:
Do u think Samsung didn't know about it even b4 releasing the phone? In a wild hope of chasing Apple's A11 bionic chip and market share, Samsung ended up screwing the in-house Exynos 9810, Samsung was never good at accepting their own faults. Have a look,

[Samsung Galaxy S9+ Questions & Answers] ssj100:
Thanks for posting your results. It appears you use your phone in a "stacked" fashion (similar to another poster above too), since your time on battery isn't much higher than your SOT. Just another example of real-world use, and that "stacked tests" would give a good battery drain reflection of such real-world use (all the following videos show S9+ exynos doing very well, coming top or 2nd):

https://www.youtube.com/watch?v=1jMnpHtK1Zg

https://www.youtube.com/watch?v=KL92Gb44Ciw

https://www.youtube.com/watch?v=QwxQNkmezpQ

It's interesting that you only noticed the improvement in battery drain after a clean (factory) reset - I always do this with every new phone (and every new laptop/PC for that matter - I think it's a good habit security-wise hehe) and I'm also getting very good SOT etc. It also sounds like you didn't do any automatic "restore" process, and re-installed all your applications manually - again, something I always do (to avoid potential software errors/conflicts etc). I wonder whether those posting 7 hours+ SOT have also done the same thing. Here's an example of a recent full drain for me (I also don't use any package disabler etc):

https://forums.androidcentral.com/showthread.php?t=883604&p=6232984&viewfull=1#post6232984

I'm really puzzled why we're getting such conflicting real-world experience by people though (just like with every single phone ever released hehe) - I wonder if auto-syncing accounts etc is one of the issues with the S9+ that causes it to drain battery faster, especially while it's supposed to be idle? Do you have auto-sync (eg. for accounts) and auto-updates (eg. for Play Store) enabled for everything? By default, they are, but that's one of the few "automatic" things I always manually disable (for security reasons, not battery reasons). Perhaps I'll try enabling them and see what my battery drain is like.
[Samsung Galaxy S9+ Questions & Answers] Virgo_Guy:
Settings>General management>Reset>Reset Settings temporarily fixed the poor battery life, but the issues return without making any changes in the settings. Inconsistent & Unpredictable.
[Samsung Galaxy S9+ Questions & Answers] ssj100:
I think "srcnDMD" was referring to:

Settings>General management>Reset>"Factory Data reset"

You can also achieve the above with these instructions:

http://www.hardreset.info/devices/samsung/samsung-galaxy-s9/hardreset/first-method/

For me, it's pretty much the first thing I do with any smartphone/laptop/PC I get. I have seen several reports around the web of people noticing much improved battery life after they did this. But again, it's difficult to know what exactly this "fixes" if at all, especially since people use their phones so differently.
[Samsung Galaxy S9+ Questions & Answers] ashwinksa:
Bro for how long was it proper? I mean after this fix did u see that android system consuming less battery ?
[Samsung Galaxy S9+ Questions & Answers] Virgo_Guy:
No didn't see android systems consuming less battery or such. Just for 2 days it was somewhat descent. Didn't do any changes at all in the settings but even then it again became like before after 2 days. Factory resetting , easing cache etc didn't help earlier, so was doing only the reset settings later.
[Samsung Galaxy S9+ Questions & Answers] ashwinksa:
As of now, is your android system consuming battery next to the Screen ??
[Samsung Galaxy S9+ Questions & Answers] Virgo_Guy:
Was this msg meant for me? Felt like so. I know that srcbDMD spoke of factory resetting and not reset settings. But I was meaning reset settings and not factory resetting and that msg was for all users and WAS NOT a response to you or him.

Any school going kid with the slightest technical enthusiasm knows that it's better to factory reset/erase cache in recovery/ b4 using the phone or post dirty flashing or post OTA flashing with an android version change etc. and stuff.

If u didn't send that msg to me, then it's alright.

---------- Post added at 08:20 AM ---------- Previous post was at 08:16 AM ----------

No bro, it doesn't. It's much less but even then battery life sucks.
[Samsung Galaxy S9+ Questions & Answers] ssj100:
The message was for anyone who may have mis-understood. Just trying to help others. I hope you continue to do the same.

By the way, can you post what apps etc you are using? And also your configurations etc. Or link to a post where you may already have done this.
[Samsung Galaxy S9+ Questions & Answers] ashwinksa:
Bro can you post a screenshot of battery stats ?? So that I can decide to factory reset or not bro. Whats your SOT?
[Samsung Galaxy S9+ Questions & Answers] Virgo_Guy:
Wonder who that noob would be to mis-understand "reset settings" as "factory resetting" that too with the path clearly shown.
[Samsung Galaxy S9+ Questions & Answers] ssj100:
Probably doesn't help to potentially insult/belittle people who may not be as knowledgeable as you.

Anyway, back on topic, looks like I'm not the only one who is curious to see your SOT information etc, if you're willing to share it.
[Samsung Galaxy S9+ Questions & Answers] Virgo_Guy:
Yup, bro, see these. These are the best I got so far and doesn't look so good. Gallery sync, cloud sync etc off, 2 email accs, one in sync in contacts, people's detail etc., Black theme, Black wallpaper, few Samsung stuff disabled, no game playing, light youtubing, location on, nearby device Scanning off, wifi power saving on, wifi on/data off,...

First one with moderate usage, 2nd one with moderate to high usage.

.. The average I get is about 4-5 hrs of SOT with a total runtime of about 13 hrs. That's way less than my previous pixel 2 xl and less than the galaxy s8 plus with similar settings and usage patterns.
[Samsung Galaxy S9+ Questions & Answers] ssj100:
Thanks for that. Do you think Facebook is the app causing a lot of your battery drain? Just had a quick glance and noticed when you didn't use Facebook as much, you managed to get over 6 hours SOT, rather than just 4 hours.

EDIT: what was the approximate average and SOT range for the S8+ and Pixel 2 XL for you?
[Samsung Galaxy S9+ Questions & Answers] ashwinksa:
This is kinda same for me too bro. Guess Samsung should patch the CPU tuning properly through firmware update :(
[Samsung Galaxy S9+ Questions & Answers] Virgo_Guy:
Not true, I checked it too without facebook app. I thoroughly checked all those, in 2nd pic though fb was used for a short time, the total runtime was less than 10 hrs, that's unacceptable.

Fb is a battery hogging app for sure but other flagships run way more than it with the app installed...

..

PIXEL 2 XL - about 8 hrs SOT with a total runtime of about 18 hrs with more battery hogging apps installed and zero tweaks.

GS8 plus - about 7 hrs of SOT with total runtime of about 17 hrs with no tweaks.

OnePlus 5T - this is steller, about 10 hrs of SOT and 22 hrs of total runtime with battery hogging apps installed and no tweaks.

---------- Post added at 09:08 AM ---------- Previous post was at 09:04 AM ----------

Trust me I'm old in all these and don't expect much from Samsung , they know it but keep mum and behave as as if all these r fine, we keep hoping and hoping and one day they release the the next flagship. They are good at security patches, good hardware, but bad at accepting faults when things go wrong.

PS: Can u update your endurance here?
[Samsung Galaxy S9+ Questions & Answers] ssj100:
I see. I wonder why your battery drain is decent for 2 days after a factory reset or settings reset, but then becomes worse? Has anyone else noticed this? Personally, I've actually noticed the opposite (with previous phones too) - once the phone "settles in" after a few days/weeks, battery life seems to get better.
[Samsung Galaxy S9+ Questions & Answers] Virgo_Guy:
I'm not alone, internet is flooded with the same.
[Samsung Galaxy S9+ Questions & Answers] ssj100:
I can appreciate your frustration - the fact that you notice it being good for 2 days but then notice it deteriorating makes it even more frustrating. And you not keen to switch back to Pixel 2 XL etc while waiting for something to improve? The next Samsung flagship will be Note 9 I guess, but that's several months away.
[Samsung Galaxy S9+ Questions & Answers] ashwinksa:
I am 82 percent battery now. Will update tonight.
[Samsung Galaxy S9+ Questions & Answers] ssj100:
Do you think you're using your Pixel 2 XL in a similar way to your S9+ Exynos? As you can see in recent posts here, at least one person has reported the S9+ getting about half the SOT as his Pixel 2 XL, which is completely different to what you're reporting.
[Samsung Galaxy S9+ Questions & Answers] Virgo_Guy:
As I mentioned in my old posts, other flagships have other issues in other departments, so staying with no luck, I'm thinking of going with the SD version of s9+, but digging up more to have better insights regarding local Network compatibilities, if it clicks positively I would end up ordering one.

------ Post added at 09:42 AM ------

Yeah, sure. ?
[Samsung Galaxy S9+ Questions & Answers] ssj100:

Its basically a like for like situation.

Battery life wild of course vary considerably between individuals as there are so many things which affect it.
[Samsung Galaxy S9+ Questions & Answers] ssj100:
Thanks for the reply. I can certainly understand that battery life will vary considerably between individuals, but we're comparing between 2 different devices (S9+ and Pixel 2 XL) with the

same

individual. As I said, you're reporting similar SOT, while the other guy is reporting

half

the SOT with the S9+. I'm not talking about 10 minutes difference or even 1 hour difference - talking about half! With everything else being equal, I'm not sure how that's possible.

---------- Post added at 07:45 PM ---------- Previous post was at 07:28 PM ----------

By the way, can everyone who posted their SOT also post more details? Especially which "Advanced features" are enabled? I have everything disabled in "Advanced features" except "Quick launch Camera", "Swipe to call or send messages", and "Direct Share". I don't use or want to use any of the other features, hence they are disabled. I don't know whether that actually saves a lot of battery life though, but who knows.
[Samsung Galaxy S9+ Questions & Answers] madvinegar:
I started to have fantastic battery life (6+ hours SOT and or great standby time) when I stopped using auto brightness. Now I turn the brightness up or down according to my needs but I see that most of the times there is no need to set it more than 50%.

I have tried everything else (dark themes, disabling various apps and settings etc) but the biggest and more substantial difference I saw was when I disabled auto brightness.

[Samsung Galaxy S9+ Questions & Answers] Virgo_Guy:
4-5 hrs sot with a total runtime of 12 hrs & about 6-7 hrs of SOT with a total runtime of 9-10 hrs over wifi is BAD..

It's been more than one and half month.

---------- Post added at 06:14 PM ---------- Previous post was at 05:58 PM ----------

That looks good only. Curious to know what's the total runtime u get with a higher SOT! And did u set up the phone with all ur accounts etc(wherever applicable) and any measures taken?
[Samsung Galaxy S9+ Questions & Answers] ssj100:
Also doesn't sound like you're using anything too heavy? What's your idle drain like? Say when you leave it overnight while you sleep - how much are you losing per hour (with AOD on or off?)? And screen brightness on auto or?
[Samsung Galaxy S9+ Questions & Answers] ashwinksa:
15 hours runtime with 4 hour and 12 mins SOT and all accounts have been setup.
[Samsung Galaxy S9+ Questions & Answers] Virgo_Guy:
Nope, no "heavy" thing at all. Standby drain over night(about 8 hrs) is about 5% (AOD stays off during night) and that's just not bad given that wifi & data both stay off.

Screen brightness Auto and I keep it that way, why? bcoz I never kept it off in any predecessors and all did good, expect s9+ to do the same. If it doesn't do like the older ones, then that's s9+'s fault.

---------- Post added at 07:48 PM ---------- Previous post was at 07:46 PM ----------

Bad, that's bad for a flagship in 2018.
[Samsung Galaxy S9+ Questions & Answers] ssj100:
Yes I use Auto brightness too, and seem to have very decent battery life like many others here. Just seeing what else could be causing such significant drain on your S9+. I wonder if it's the Wi-Fi? Although you've implied that you get even worse battery life with mobile data instead. I just mention Wi-Fi because I have noticed that in some locations/areas that I'm at with Wi-Fi enabled, it seems to drain much more perhaps due to relatively poor Wi-Fi connection? One such location with free Wi-Fi times out your connection after a certain period of time (about an hour?) and you have to agree to terms/conditions again etc - this Wi-Fi seems to drain the battery an extra few % per hour during idle times. While with my home Wi-Fi, I don't notice such extra drain.

Apart from Facebook and using these forums, what else are you doing with the phone that would at least moderately drain it?
[Samsung Galaxy S9+ Questions & Answers] Virgo_Guy:
Very good WiFi connectivity, full signals and with an uptime of 99% via a dual band router and is set to 2.4 GHz band to have no network interruption.

Im a light to moderate user- twitter, instagram, some fb, few wtsapp, max an hr of YT, reading news articles for 2 hrs or so with rare video playing ... An hour of phone calls,, no unnecessarily apps installed. I'm a techy and very well know how to use a smartphone, so rest be assured that there isn't anything user-defined(me, in this case) going on. It's "something" hardware and the OS based that's not coping up well. That's why I used another s9 plus for few days, only to get similar results, the owner of the other s9 plus cearly told me how unsatisfied he was/is too with it due 2 its "weird" nature.
