Exactly. LTE standby drain is horrible during day time, when doze is obviously not active for most of the time.

Could you extend your your test a bit further? 2 to 3 hours? And try to not let them sit on the table. Don't let doze kick in. I want a real world usage difference. Try to carry them both in your pocket.

If possible, install BBS too. A look at kernel wakelocks would be interesting.

No. I for one didn't jump on to this bandwagon after Anandtech brought forward their findings. From day one I've been critical of the horrendous battery drain on this thing. While on wifi it's okay, LTE standby drain is the point of concern.

Most of the guys in such forums were already expressing their concern over it. It's just that a technical finding brings about a better perspective to the situation. Have a look at their second article where they tune the kernel themselves. Massive improvements in battery life.

And by the way, the guy doing those measurements over at Anandtech, is a XDA member. Peace.

Well, I have really decent battery life with my Exynos version, and I have seen many users with decent battery as well; same case with the Snapdragon, that I have been seeing people with good and bad battery life with it.

I think is more than a user problem than a processor unit, because as long as you configure properly the device, it will give you good battery life.

Not all the Exynos have bad battery life and not all the Snapdragon have better.

[Samsung Galaxy S9+ Guides, News, & Discussion] Cristi10:
Today was a heavy usage day. I know i charged when i got the chance, about 28%, so now it should be around 14%. But still it's very good in my opinion. As you can see, i took lots of pictures, browsed a lot, and social media, snap and fb. When i was out i was on data and inside on wifi. Also i found that deleting apps from unmonitored section reduces wakelocks and disabling background activity for android system helps. Exynos variant.
[Samsung Galaxy S9+ Guides, News, & Discussion] zathus:
Well, a 30 second battery test is hardly... anything lol. They even said a real world usage will come later... which I'm very interested to see.
[Samsung Galaxy S9+ Guides, News, & Discussion] lawtq:
I've had both versions. Sent exy back for to dropped calls

The snapdragon version has no call problems and the battery lasts longer. Gpu noticeably better too.

I start charging with 8 sot and about 15% battery remaining. That's really good for the battery size

Exynos gave me got battery too. About an hour less sot
[Samsung Galaxy S9+ Guides, News, & Discussion] thorcyar:
what is this option ? how is that you (we) can limit the "system background usage" (WHAT usage ?) ?

for me I get bluetooth kernel wakelocks if I let the bluetooth setting "on", and it seems to have a visible impact on battery life (if I switch my headphones on, they connect instantly even if screen is off, so basically the phone is not at full rest)
[Samsung Galaxy S9+ Guides, News, & Discussion] Galaxo60:
I'm sorry, but Snapdragon version also suffer the problem with calls, that's why many people from US is reporting as well, because is the only version sold there.

Regarding GPU, is true, Adreno is still better than G72.

;)
[Samsung Galaxy S9+ Guides, News, & Discussion] lawtq:
Calls are perfect for me
[Samsung Galaxy S9+ Guides, News, & Discussion] Galaxo60:
Neither do I have a problem with the calls, and I'm using Exynos version, but others are suffering the problem no matter the processor version.

[Samsung Galaxy S9+ Guides, News, & Discussion] lawtq:
Strange then. Luck of the draw? Anyway the snapdragon has been impressive for me. Sips battery and just as good performance as the exynos I took back which had the above problem

[Samsung Galaxy S9+ Guides, News, & Discussion] zelendel:
I hate to say this but It maybe the carrier. I was recently in Pune and Dubi and I got a Jio sim card while I was there and I noticed that battery life and signal connection was far worse then back in the states with the same device.

Battery life

Please to report that after almost two weeks of doing a factory reset my battery life continues to be good on LTE and excellent on wifi. One or two members had predicted that the battery improvement will just be temporary, but i guess i am one of the lucky ones. Hope i dont jinx myself lol.

When at home on wifi I easily get around 26 to 30 hrs of total standby with sit of around 6.5 to 7 hrs which includes mostly browsing and watching streaming videos on youtube.

On mobile 4G i get around 5 to 5.5 hrs of sot with total 20 hrs of standby which is good enough for me.

As you were talking about Pune, my battery life suddenly deteriorated as i shifted to Chinchwad. I was using Jio as my second aim. Since the time i have stopped using Jio battery life has improved drastically.
[Samsung Galaxy S9+ Guides, News, & Discussion] billubakra:
Since you watch videos mostly, how bad is the black crush screen issue in day to day usage?
[Samsung Galaxy S9+ Guides, News, & Discussion] Chirag22ster:
To be very frank i still havent exactly figured out what is the exact issue with black crush. That day i tried to watch some dark scene videos on my obone and my wifes note 8. The black shades appeared pixelated on both screens. I also tried to put the leaf wallpaper from samsun theme one both phones. And on both the phones the wallpaper showed smudging of the dark coloured scene.
[Samsung Galaxy S9+ Guides, News, & Discussion] billubakra:
So that issue is present in the older phones too? Wth is Sammy doing?
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
It's present on every amoled screen. It's just that it's quite pronounced on S9+.
[Samsung Galaxy S9+ Guides, News, & Discussion] billubakra:
Yes you told me so in some other thread but the use above and me personally weren't able to find it in our older phones so I thought maybe it was present in some older phones.
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
If you know what you are looking for, you'll surely find it on very amoled panel out there.
[Samsung Galaxy S9+ Guides, News, & Discussion] billubakra:

[Samsung Galaxy S9+ Guides, News, & Discussion] Cristi10:
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.

Today's results, i was away since morning always connected to lte, when i got home switched to wifi. It really shows that it depends how you use your phone and sot is fluctuating. I used my phone as a hotspot for like 3 hours today and i didn't always had the best reception.

Mine is back to perfect battery performance. I was having an app wen crazy that sucks 50% of battery... Solved.
[Samsung Galaxy S9+ Guides, News, & Discussion] -Vulture-:
Can only speak for my Exynos S9+ Duos, gives me 2 working days of battery life with 4h of SOT. I also achived over 7h SOT on a single day with heavier usage. It really depends on your usage, installed apps and maybe some optimisation you can easily do yourself, like disabling data connection while on Wifi.

But Standby drain is a bit high for my taste, thats true. 1% in 2h over night is a bit too much. But lets check what the newest BRE5 firmware is up to. Installed it today, but have to check its standby drain first.
[Samsung Galaxy S9+ Guides, News, & Discussion] skivnit:
Lol what??? Definitely not right
[Samsung Galaxy S9+ Guides, News, & Discussion] ssj100:
Sounds very similar to my Exynos. I also have AOD enabled though, and my idle/standby drain is almost exactly 1% per hour (with AOD enabled and in use).
[Samsung Galaxy S9+ Guides, News, & Discussion] Chirag22ster:
I easily get around 5.5 to 6 hrs of sot with 26 to 28 hrs total time and 6.5 to 7 hrs sot for heavy use with 18 hrs of total time. No package disabler used. No mods.*

I use a black theme. Have changed one or two small settings for google app which doesnt affect the functionality. Notifications on only tor imp apps like whatsapp,sms,twitter etc.

Try this. Really worked for me.

[Samsung Galaxy S9+ Guides, News, & Discussion] ssj100:

My usage today. As you can see, i also had some heavy usage on google maps. The phone was shut down while i was applying a screen protector. It was 60% wi fi, 40% 4g.
[Samsung Galaxy S9+ Guides, News, & Discussion] Chirag22ster:
My overall battery life in unaffected and good. But I have kbserved that over the past few days my battery drains faster from 100 to 94 and then settles doen. Is it because of some calibratikn issue? I bought the phone 2 months ago. Over the past 2 months i remember kewping yhe phone charging overnight inadvertently at least 8 to 10 times. Can this be the cause?
[Samsung Galaxy S9+ Guides, News, & Discussion] Cristi10:
It seems that after the may update battery life is better. At least the standby is improved, i will see in the following days.

I just bought the s9+ exynos model off ebay from the seller nevermrsp for 699.. I haven't opened it should I return it since so many people are having poor battery life? If i open it and return it after there is a restocking fee of 20% i think, but I am on an iphone right now and i want to go back to android
[Samsung Galaxy S9+ Guides, News, & Discussion] Oemenia:
Has the update done anything to improve performance and battery life. I refuse to believe Samsung messed up this bad.
[Samsung Galaxy S9+ Guides, News, & Discussion] harry92008:
Nothing on the battery front. Didn't notice any significant difference in the performance either.
[Samsung Galaxy S9+ Guides, News, & Discussion] Galaxo60:
For me, it increased battery life a little bit and the phone feels smoother. It also fixed the banding in dark scenes.

I'm speaking about BRE update, but it seems is not the same for all the markets.

I really don't understand all the reports about bad battery life and SOT on the S9+ Exynos!

Reports of 4 hours or less SOT?!

I bought my phone 2 weeks ago, and I never got under 6 hours SOT!

I installed SoLdieR9312 G965FXXU2BRI1 ROM.

This is my settings:

- I use resolution WQHD+

- WiFi allways ON

- Always on display enabled except from 00:00 to 8:00 and when I'm using the phone or in my pocket

- 4G LTE always on

- Location high precision always on

- Bluetooth always on connected to my watch sending mails and all notifications

- Auto brightness

- No power saving options except that I have added lots of apps to make them allways sleep when I'm not using them (there are some battery drain apps)

- I use a black theme that may help a little

A normal 24H day for me, where I've played for almost 4 hours outdoor and still had 10%:
[Samsung Galaxy S9+ Guides, News, & Discussion] thierryhenry1886:
my battery life was always like 5 hour on hd+ and powersave i got 6hour max.

In 4G (i open when its necessary) connection i am getting 3.5-4 hour screen on time (no gps services.)

My biggest unhappiness is battery life.

S9+ exynos version latest BRI3 firmware

And every night my phone lost %10 battery when i am sleeping. Isnt it too much?

[Samsung Galaxy S9+ Guides, News, & Discussion] Firaristt:
That's not normal, comparing to my usage. With 3G/4G/LTE-A mixed connection (Turkcell) in İstanbul I got between 4-6.5H SoT with 2K+ res, power saved SoC and auto brightness.I generally plug it before %15, so you may add an additional %10-20. Are you using Vodafone as provider? And according to my experiences changing resolution makes little change if you don't play games.
[Samsung Galaxy S9+ Guides, News, & Discussion] thierryhenry1886:
Yes, i use Vodafone. I dont know this firmware thinks so strange. I was using germany BRI1 (dbt) firmware. I was getting 2.5k/8k geekbench score. Now i am using Turkey BRI3 firmware. I am getting score that i attached.

Battery life is always different. In 4.5G %50 brightness , no AOD 2K screen solution. I get max 4hour(but when i am out, i always listen music until i come back home. I think that drains %10). In wifi 5.5-6 hour. Phone is clean no unnecessary apps, lots of future are closed (just dolby on).

Also as i said in every night it drains %10-15 but wifi on and sync on.
[Samsung Galaxy S9+ Guides, News, & Discussion] Firaristt:
Have you checked what is draining battery other than connections(provider, wifi, wireless headphones etc)? Probably something keeps updating itself/it's service in the background or something keeps crashing in the background. You can check crashes with adb logs.

New phone 101

It is a known fact that people spend more time on new phones, and that makes the battery drain faster. Couple that with the fact that most are likely comparing it to their day to day usage on their old phone, and not the battery life from the first couple of days with it.

In reality, the S9+ has the same capacity as the S8+, and the battery life is extremely similar.
