I know all depends what each person optimime his phone, but after a few years running android, i see new phone is good first 6 months, then is getting bad.

My s8 plus was stable until this last update, now is less 1h sot.

I assume new s9 plus, last a little bit longer.

But soon i will post some feedback.

I will flash the unlock version, its have a couple apps less and see how it goes.
[Samsung Galaxy S9+ Real Life Review] M7mdA7md7sein:
Congratulations :D

May you share your installed firmware/software version ?
[Samsung Galaxy S9+ Real Life Review] Dawid Cxod Nowak:
Seems I'm one of the few with low SOT.

I'm a long time Iphone user with bad android experience, yet I love android.

Turned off all background activity on all apps. Doing daily calls, BT active at work for couple of hours. Wifi at home, doing some netflix during lunch, facebook and messenger usage at normal levels. If i'm lucky I get 1-1.5 hour sot and I'm down below 80% and almost at 70% sometimes.

During nights it can drain 2-3% while my old Iphone 7 plus drained like 1% at most if nothing.

Only got auto lightning on, flip cover, and sync. No location, no nfc, beam, wifi scanner, no edge or edge light.

I love the phone but the battery just not anything to clap for compared to my 1.5 year old iphone 7+
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
Your sot is rather low and unacceptable .Hope you followed the basic steps mentioned here (post #215)

...

Finally, UNLESS you try to squeeze out every single bit out of the S9 plus , I assure you , the battery life on the iP7+ is better in terms of total endurance, sot and standby drain.
[Samsung Galaxy S9+ Real Life Review] samitro:
My first charge, I was expecting worse than that, if it remains like this I'm happy, it is Exynos running latest BRE5
[Samsung Galaxy S9+ Real Life Review] ssj100:
Looks good, especially for a first charge. Always On Display off? Any other battery related tweaks?
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
I understand, as I get the same pain when I keep switching between iOS , stock Android or near stock like Oxygen OS and then an Android Environment with several "duplicate" stuff and most of them personally I "dislike" [MENTION=381438]samsung[/MENTION] that eats up resources and kills battery...

Photos and Gallery are basically the same. Photos u can uninstall, Gallery you can't. Why not uninstall the first and get some more juice ? And do cloud sync Gallery only when necessary.

..

Another step that I 4got in the earlier list:

Settings>Connections>Data Usage>Data Saver. Keep it on. It reduces data usage of unused apps in the background and saves battery.

..

Greenify is a really good app that identifies and puts "misbehaving" apps into "hibernation" when not in use and thus stops them from lagging & leeching the battery. With "Doze", its just better. Download it, install and grant in adb.

That sot will increase with those steps followed. I agree with you that some manufactures make it simply hard to sail through flawlessly.
[Samsung Galaxy S9+ Real Life Review] samitro:
AOD off, GPS location tracking and history off as usual, Google now off, no other tweaks, no apps disabled (I did not install any Samsung app at the first boot). I changed the theme to black few minutes before I took the screenshot. I was home though over the weekend and over WIFI all the time but I do not have very good coverage with S9 for some reason.
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
AOD and Location tracking - two big killers...

...You are using a VoLTE network, just keep the network mode in "LTE Only"(if haven't already), you gonna get stronger signals than without.
[Samsung Galaxy S9+ Real Life Review] ssj100:
Nice. Some people here are reporting much worse SOT and battery endurance despite a lot more tweaks than you. Your screenshot suggests you would get probably 6 hours SOT with 50+ hours on battery - this is with presumably light to moderate use, and fits with my own experience (although I would have about an hour less SOT due to having AOD enabled all the time over such a long period on battery).

Could you post a few more screenshots or report your battery stats for your subsequent cycles? I am having very consistent battery drain but there are some reports of the opposite.
[Samsung Galaxy S9+ Real Life Review] samitro:
I do not have the option with LTE only, the only option with LTE is "LTE/3G/2G auto connect"
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
Yeah, its carrier dependent. Carrier like Jio(entirely 4G/LTE and no fallback 2G/3G support of its own) shows an option of "LTE only" no matter which slot its insert into.

Do you use auto brightness, bixby , social media apps, any cloud based syncing @ your earlier posted SOT?
[Samsung Galaxy S9+ Real Life Review] Dawid Cxod Nowak:
Thanks mate!

Will do this, just quick question, How do you grant it in ADB?

I've noticed that data saver kills a lot of notifications. Phone calls through messenger dont come through, emials and so forth. Thats a bummer..
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
First, Install greenify app, open the app and select "my device is not rooted">grant permission">select greenify and select allow usage tracking and allow it. Then click the back button and "finish it".

Next open the greenify app again>3 dots on upper right corner>Aggressive doze>select it. Here u would need to give adb shell permission.

How to as per the link :

https://greenify.uservoice.com/knowledgebase/articles/749142

...

Its not. Just do this :

Settings>Notifications> and keep notications on only from apps/services you need.
[Samsung Galaxy S9+ Real Life Review] xmatharux:
Just tried 'Naptime' app with ADB commands and aggressive doze - doesn't look like it does much but it has a nice tracking feature to show when your phone enters/exits doze.

To people with great battery life - what are you % of doze time? i.e. mine is around 70% and 3% battery drain per hour

One of my best times ever:

:)
[Samsung Galaxy S9+ Real Life Review] Target7:
Hello,

I have a S9+ since its release, in Europe so Exynos model I guess, and I can't stand more than 2h in SOT... When screen is ON its incredible how I'm losing batery, never experienced that with my former S3, S5 or S7 edge...

Today I woke up at 12, and at 4pm I was 15%, with only some Facebook, some mail, and 15mn of spotify and Waze...

Even with data synch disabled, eco battery mode ON, everything extra options disabled, it's still a scandal.

Last firmware via OTA.

Than, before resend the phone to Samsung, I have planned to try my last opportunity : hard reset, wipe cache/battery, install a firmware via Odin, and don't put any backups, just readd my photos/video/apps manually.

So here my two questions :

- which firmware should I install ?

- what are all the steps I must not forget to havea clean phone and particularly their order ? Do i have to wipe cache/battery before installing the firmware with Odin, or do the contrary ?

Thanks in advance !
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
You dont need to ask which sw version to use, use the latest version only.

Now take these steps:

(A) As [MENTION=9156259]Sobertooth[/MENTION] mentioned earlier,do this : After inserting sims(exactly I too do this with every phone)

(b) Check for system update, download and install.(doesn't need to be installed via odin)

(c) Switch off

(d) Press volume up, bixby and power off swtich all together ,release when Samsung screen appears

(e) Select wipe data/Factory reset and do so

(f) Reboot

(g) Go through the setup process, install apps

(h) Repeat step (c) and (d)

(i) Select Wipe cache partition , do so and reboot. ( its unnecessary cleaning cache before installing the OTA or firmware via odin).

..

(B).

Next do this:

1. Use a black theme and wallpaper.

2 . Go to cloud and account settings and stop syncing whats not necessary to sync as per your requirements and remove accounts you do not find yourself using.

3. Uninstall apps you do not use at all.

4. Uninstall and disable bloatwares.

5. Keep apps in always sleeping mode that you often don't use.

6. Keep display brightness to manual and not auto .

7. Go to improve accuracy in location settings and keep Wi-Fi scanning off.

8. Keep AOD off or use it in a specific time frame.

9. Keep "mobile data turned on" option in developer options and keep it off.

10 .Go to advanced features settings and keep features off that u don't require.

11. Keep gallery syncing off and uninstall google photos.

12. Use greenify app and grant permission in adb.

13. Settings>Connections>Data Usage>Data Saver. Keep it on. It reduces data usage of unused apps in the background and saves battery.

14. Settings>Notifications> and keep notications on only from apps/services you need...

....

Then wait for few days to let the OS settle down(say a week) and report back: Good luck:good:
[Samsung Galaxy S9+ Real Life Review] Target7:
Thanks mate. It is currently rebooting after the wipe data reset. I'll go throught next steps after dinner. Hope I'll eventually reach +2h SOT ! Keep you updated.

Nice, very good standby drain - AOD disabled helps a lot there!

Been a little while since I last posted a screenshot hehe - here's another one. It's been very consistent. For me, I see no need to use "tweaks" like disabling AOD or using a black theme.

[Samsung Galaxy S9+ Real Life Review] mtm1401:
What have you done to get that?!!

I comfortably get 5 hours of SOT but that's over 15 hours or so...

Can't seem to get my screen off drain below 2% an hour even with AOD off

sungstromeda:

no root only adb work:)))
[Samsung Galaxy S9+ Real Life Review] bassgenerator:
GPS battery saving. I do not use AOD is not useful to me. I do not use Facebook or messenger but telegram and viber. GMAIL sync is one account. Maximum display resolution WQHD, disable 122 bloatware Samsung and MS Office. Dark theme important. Scan close devices off. This is the path and this is the key to success. Sungstromeda and System MOD module !!!!

Touch Wiz to replace Nova Launcher. Do not use Chrome that destroys the battery by 50 percent more. but Samsung browser. Despite these enhancements, enjoy all of Samsung's features.
[Samsung Galaxy S9+ Real Life Review] Target7:
Hello back mates,

After a wipe data factory, manual installation of apps, manual pictures backup, and a wipe cache, still can't even reach 2h of SOT... :crying:

If I use my phone when it is charging in low speed, (computer USB, car USB or even external battery USB), I loose battery, (around 1% every 5 minutes). If is chargin in low speed and let my screen off, it charging extermely slowly (around 1% every 10mn).

I have no any solutions to try... First time in 10 years and 5 different Samsung phones that I experience that. I know that at the beginning Samsung often take time to realease an update adapted to last android versions with a good battery, but here it has already been several months, and when I saw people experiencing +5h SOT or even a extreme case of 15h I'm just getting insane. :cowboy:

AOD OFF, battery eco mode ON, high accuracy GPS OFF.

This morging in the subway, 30mn of Spotify only (I know that is an hungry battery app but my songs are offline so no data), I lost 20% ! More than 3% every 5mn !!!

Should I consider to a go a shop and start complaining ? (I bought the phone through my phone network operator (the phone only, no mobile contract), can I even do that ?

Thank for your help.
[Samsung Galaxy S9+ Real Life Review] mtm1401:
What's your total phone on time with 2 hours SOT?

If you've done the above steps and it hasn't made a difference it's most likely broken. I don't think I could force my phone to die with only 2 hours of SOT unless I left it idling for a few days.

I'd take it to a Samsung store or return it to the network provider. It will be in warranty so they are legally required to fix/ replace it.

Explain what happens and the steps you've taken to rectify as no doubt they'll tell you to do a reset etc.

Hopefully get a nice shiny new device
[Samsung Galaxy S9+ Real Life Review] bassgenerator:
yes shiny new device or the phone with black crushing as a bonus: Smiať:: Smiať:: Smiať:

Looks like that adguard is hammering your battery, why don't you use the built in one on Samsung browser?
[Samsung Galaxy S9+ Real Life Review] bassgenerator:
Adguard consumes a lot of batteries. Fake apps. only SABS. I can imagine better statistics
[Samsung Galaxy S9+ Real Life Review] shaggyskunk:
SOT of 2 hours is definitely not normal... I'm pretty sure that I could be running bench tests continuously for much more than 2 hours with the screen on the whole time - Since you have already done a Factory Reset - You might want to try running your device in Safe Mode for a few hours and see if you can get at least 5 hours of SOT (just to rule out any misbehaving apps).

If you can achieve at least 5 hours of SOT in Safe Mode then it's more likely to be a user installed app than the device itself - I'm usually getting ~7 hours of SOT Fwiw ?

[Samsung Galaxy S9+ Real Life Review] ssj100:
Is "Adguard" is the same as "Adguard Content Blocker"? If so, I've used that for years, and I've never seen it show up in my battery stats. That is, it doesn't appear to use any significant battery for me. I suppose if you're using apps/browsers that have huge amounts of ads to block, then it would use more battery?
[Samsung Galaxy S9+ Real Life Review] gyuri81:
what's the status bar? do you add a link? thx :)
[Samsung Galaxy S9+ Real Life Review] Dawid Cxod Nowak:
So i've done the following, and have tried out the phone in the past 1.5 week.

As of now its a lot better, but there are things that still bother me. While battery time has improved notifications with datasaver need to be manually updated in the settings. Allowing notifications to go through while datasaver is on.

On top of that, I still dont get all the notifications from messenger or facebook.

Currently with BT on during my work day, minor usage like one hour SOT. Some calls, and some inbetween usage of facebook, messenger and chrome.

I land on 60-70% battery left.

Last weekend I let my phone just be on and check on it how it behaves since I dont use it while being at home.

So the only real option is use it through a browser... and then messenger too?

Why the f**k have they not fixed that yet.... I've had the same issues since galaxy s2...

And everyone is saying how good android is, while 50% of the issues are still there bugging around.
[Samsung Galaxy S9+ Real Life Review] shaggyskunk:
FB has a bad reputation (aside from the fact that they sold your personal information!) for sucking the battery - There's alternatives like Metal (I don't use FB, WhatsApp or Messenger etc) but from what I've seen it's less to do with Android and more to do with poorly designed apps that are more interested in selling your privacy than building apps that do what you want... My 2 cents ?

Sent from my SM-G965W ??
[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
Nice to see that you are getting better batterylife.

..

Keeping datasaver ON doesn't indirectly keep the apps notifications OFF. When you keep the Notifications for all apps OFF, you need to manually toggle notifications ON from apps you need real time notifications from.Hence I'm not having any issues getting notifications from messenger or FB with datasaver on. If you still want those apps to get full freedom of working in the background just choose "Allow app while datasaver on".(don't get confused with the working of datasaver and notifications). Hope you are not getting confused or conflicting anything.

I recommend swipe for Facebook/ messenger
[Samsung Galaxy S9+ Real Life Review] cavags5:
Facebook is not that bad as you say, all depends on the usage, and inside Facebook you can block the pop ups.

There is worse apps than Facebook, like messenger, instagram or aliexpress.

I never had Facebook drain, only aliexpress its the app that optimised still drain without using,

The problems with drain, is only in 4G, because in Wi-Fi is perfect.

Only need to know how to optimise your phone.

I don't use data saver or power saving,

[Samsung Galaxy S9+ Real Life Review] Sabertooth:
fb drain hasn't been any issue 4 me too. I don't think fb should b considered as a big negative factor whn checking batterylife. Like u said there are other applications that drain more than fb. To put into prospective I compare batterylife of smartphones including fb installed.

[Samsung Galaxy S9+ Real Life Review] Virgo_Guy:
Gsmarena came up with their as usual "long term review" for the exynos s9 plus declaring 4 to 5 hrs as average SOT and they agree with the batterylife inconsistency(pointed out by Anandtech and Strategy Analytics earlier). I felt it since day 1 with no changes whatsoever post all the OTAs. Batterylife became ofcourse better but I would say that's due to doze , other factors and workarounds involved that held true to the predecessors as well and not convinced that it's due to the OTAs pushed so far as with those steps considered, for me batterylife pre and post OTAs - was and is better but similar and the nature of inconsistency still remains ).

[Samsung Galaxy S9+ Real Life Review] ssj100:
Recently updated to the June 1st security patch and had some heavy use with GPS navigation on high accuracy again (with bluetooth connected to the car and music playing too). Still happy with battery life and it's much the same as it was from the start - see attached. Was on mobile data for about two-thirds of the time, Wi-Fi the rest. AOD enabled 24/7, but given quite heavy use in general, AOD was only "in use" for just over 3 hours and therefore didn't use much battery in this cycle.
[Samsung Galaxy S9+ Real Life Review] Venom0642:
Ignore my post on top seems like some idiot's were posting false issues on Exynos and unlocked, i apologize for that. Have you try going to recovery and wipe cache, if that doesn't resolve your battery issue i suggest which no one likes but if want to try to resolve battery issue i would do a factory reset hopefully that will fix your issue.

Some moron that posted false stuff on S9 and S9 Plus, So i do apologize for giving wrong information, Next time i will do more research before i post something like this. And yes your correct i have heard more positive stuff on S9 and S9 Plus Exynos and unlocked and Snapdragon. Which i have the AT&T S9 Plus Snapdragon.
[Samsung Galaxy S9+ Real Life Review] GodXen:
Ok, seems like nothing else left. I hope factory reset will solve that.

I hate to set up my phone from scratch again, but can't live with that battery drain either
[Samsung Galaxy S9+ Real Life Review] Galaxo60:
This was my battery on the first cycle using the phone all day, Exynos version:

I'm happy with the battery, but I was so mad with the consumptions in stand by, when sometimes I would get even 30% battery drain overnight.

I disabled a lot of options in the settings related to searching for things and usage of sensors, and so far that helped me a lot with the battery drain. Maybe some of those are crushing your battery.

For those who achieved 7-8 hrs of screen on time:

HOW?

On s9+ exynos, I use FHD, aod off, disabled/uninstalled unused apps (facebook linkedin etc), turned off nearby scanning, location history, bixby

and my maximum sot was 5-6 hrs during a 22 hrs up time
