[Samsung Galaxy S9  Real Life Review] CjsS9:
I brought a S9 in Aug 2018 and it was working fine, getting a SOT around 4+ Hours till mid Dec however since then the SOT has dropped to 2-2.5 hours. Majority of the battery is been drained through Andriod System. Battery drain during night when its Ideal is around 30-40% in 7 hours stand by. Have taken the phone to the Samsung service center on 20th Feb after following all suggestions on different forums. Got the phone back after a day and working fine for a couple of days but then on Friday evening it was back to doing the Android System drain.

Got it back today to the service center and they are not ready to accept that there is a problem. Have forced them to look at the issue after talking to Samsung Customer care and will wait for tomorrow to collect the phone and see if something has improved.

For any one facing this issue can you check one more bit on the Phone. When you open your messages and read a message it flips back to the message home screen. Mine would not even let me type a message. It can take from 30 sec to 2 min for this to refresh.

S9 running stock pie,no root,january security patch.???.... made a bet with my wife to see how much i gonna keep it stock so i got to get used to this sot for the next couple months ???
[Samsung Galaxy S9  Real Life Review] sprintomatic:
After pie update, SOT went down to 3hrs from 5hrs. No new apps, same settings. Very disappointing. phone used to last all day, now its like the S6, dies half day. Never buying samsung product again.
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
You may have seen that the S10 has an impressive battery life, and it's a huge improvement over the galaxy S9, even the note 9 in some cases...
[Samsung Galaxy S9  Real Life Review] *Detection*:
Factory reset after a major OS upgrade like that, battery life usually takes a hit otherwise
[Samsung Galaxy S9  Real Life Review] CjsS9:
Hi All.... Got the Issue resolved for Android System eating the battery for myself. .... Not sure if this would work for others. Get a New Sim card from the provider. I have replaced my Sim after doing a time and motion analysis and the data from the Sim card was not able to configure with the System. MY SOT is back to 5.5 hours really happy after struggling for 3 months.
[Samsung Galaxy S9  Real Life Review] sprintomatic:
Which carrier are you with?
[Samsung Galaxy S9  Real Life Review] CjsS9:
Using the Phone in India with a Dual Sim. Issue was with Airtel Sim
[Samsung Galaxy S9  Real Life Review] i_piss_on_apple:
Maybe I should try the same cause this is abysmal..
[Samsung Galaxy S9  Real Life Review] techhahn:
I should have come here before buying s10e (Exynos). Battery life is horrible. Getting 3-4 hrs SOT on light usage. Samsung Sucks. Battery drains even faster with the dual sim card.
[Samsung Galaxy S9  Real Life Review] $ilent:
I'm set to get around 8 hours SOT from my s9 exynos. I use package disabler to get rid of all that stock crap like Facebook etc. I use bluetooth and location 24/7 and auto screen brightness. wifi is off and so is AOD, NFC etc.

Crazy how good this battery is.
[Samsung Galaxy S9  Real Life Review] xo.en:
Nice, nice...
[Samsung Galaxy S9  Real Life Review] bravelion1:
Galaxy s9 exynos.

I can get 7 hours of SOT till the battery dies completely. Running on android 9 pie.

Tested doing mostly YouTube and browsing, a bit of gaming as well. TIP: Be careful what you install, some apps can drain the battery alot and the phone won't be able to really tell you that for some reason.
[Samsung Galaxy S9  Real Life Review] RootNightmareX:
What do you recommand me guys between s8 and s9 for battery?
[Samsung Galaxy S9  Real Life Review] Theandroidfan:
How!? Did you use low brightness / auto-brightness?
[Samsung Galaxy S9  Real Life Review] bravelion1:
Well, keep in mind that I've used the phone non stop from the time of fully charging it...usually the battery drains even if you dont use the phone during the day , so that could be why i got 7 hours, also, i used auto brightness and i was in my home so i guess it was set to the middle.
[Samsung Galaxy S9  Real Life Review] wlodar1234:
S9 Exynos Stock XEO

SOT after installing Package Disabler and configuring settings. Before modifications it was on average 2.5 to 3 hours.

Edit: Today's result is even better :cool:
[Samsung Galaxy S9  Real Life Review] MetalSem:
Which packages have you disabled?

Thanks.
[Samsung Galaxy S9  Real Life Review] Dgsmd:
I must have got the **** phone of the batch

I only get 1h, 1h30m if I'm lucky of SOT on my s9...

Any tips?
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
Can you post a screenshot so we can get an idea of what's consuming your battery?

After Pie update I have some problems: only 3 MAX 4 hours on SoT, S9 is continuously warm and sometime hot (doing normal thing, WhatsApp or Youtube with low brightness). My S9 is brand new, so my battery have no problem. It is a problem that Im the only?
[Samsung Galaxy S9  Real Life Review] Theandroidfan:

My battery life is getting even worse even though I wipe the cache after each and every update...

Battery health on Samsung info app is 100%.
[Samsung Galaxy S9  Real Life Review] Diddymies:
You should do a full factory reset, rather than a cache wipe.
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
In this case I'll have to do a factory reset after each update, doesn't it affect my phone's performance? I've seen some people who did factory reset and they haven't seen any improvement in battery life.
[Samsung Galaxy S9  Real Life Review] babyboy3265:
Whats your ROM and KERNEL?

---------- Post added at 03:20 PM ---------- Previous post was at 02:55 PM ----------

Hey so i will write up what happened to me and how it improved it. Counts for you and everyone else here who wants to improve their battery. S9+ Exynos.

I used to be on OREO and got 6h easily. Custom ROm and KERNEL. Then some week ago i moved to PIE and my battery went to the toilet. 4h SOT max with minimum resolution (cant see a difference) and with Elemental X KERNEL under clocked. PIE=crap battery.

Then I found by mistake here on XDA a forum talking about Magisk module called "LKT". I installed and set its profile to Battery. Now my SOT is about 6h no sweat. I noticed no performance degradation whatsoever. As of writing this, i have 40% battery and 3:31h SOT. Android System 8%, Android OS 5% and Device idle 3%. 9h on battery total.

I fully recommend you to try the LKT module. it really works!!!
[Samsung Galaxy S9  Real Life Review] Haxomen:
Ambasadii rom with its kernel, underclocked in MTweaks
[Samsung Galaxy S9  Real Life Review] babyboy3265:
When you say under-clocked, what frequencies are you talking about? Can you attach a few screenshots? thanks

Android System use too much battery.
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
Try to wipe cache...
[Samsung Galaxy S9  Real Life Review] jossy29:
too much? I have a Galaxy S9 Unlocked Exynos Version. I usually get 90 min Screen On time. My Android-System drains too much. Sometimes about 40%.:crying: I have tried everything: factory reset, cache wipe, secure mode, nothing happened. Do you know what I can do? My settings AOD off, FHD+, Bluetooth off, mostly Wifi, sometimes 4G.

Thanks to your help.

I can not upload a Screenshot. Here for example: Battery at 4%, Android-System: 36% Screen: 10% at 1h 40 min, Android OS: 9%, com.android.systemui: 5%

Last charge: 8h 50 min ago
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
This is what I usually get since I updated to one UI.

I was able to get 5 hours of SOT when I was using oreo. Now, I rarely reach 4 hours before the phone dies.

And when the battery is at 15%, it barely lasts 4 to 5 minutes.

I don't know if this a software problem or my battery isn't in a good condition.
[Samsung Galaxy S9  Real Life Review] onlyonemail:
What application are you using, can you tell us how
[Samsung Galaxy S9  Real Life Review] wlodar1234:
Package disabler, but has stopped working after some update.. :/
[Samsung Galaxy S9  Real Life Review] onlyonemail:
don't update if you have that risk, updates only reduce performance so you have to buy the latest series ?
[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
I am noticing a slight improvement in battery life after october update. In this screenshot, even if android system has taken 26%, I still managed to get 4hr + of SOT.
[Samsung Galaxy S9  Real Life Review] wlodar1234:
With the Package Disabler installed and after disabling unnecessary applications - (a few pages back I inserted a screenshot) it was not a problem to achieve (using WiFi) SOT over 8 hours. Without Disabler using WiFi, achieving 5h SOT is sometimes hard .. Fortunately, I found a replacement for a non-working "Package disabler" -> "CCSWE App Manager (Samsung)". For now, everything works well and turns off applications without any problems.

[Samsung Galaxy S9  Real Life Review] z4nD4R@gs2:
Hello,

after last (I'd guess October) update I have noticed a slightly worse battery performance. Just personal feeling (usually I was able to finish the day with ~40% batter, but after update now I finish the date with ~20%).

Does anyone has the same "feelings"?

[Samsung Galaxy S9  Real Life Review] jamil aboudaher:
I noticed a better battery life after october update. I have the exynos model.
[Samsung Galaxy S9  Real Life Review] sesser:
what you people do for 5hours a day on a phone?! I usually got about 1.5-2h max.
[Samsung Galaxy S9  Real Life Review] Haxomen:
Some people do work over phone, some play games, some watch videos, its a portable device after all. Battery backup is of essence in a portable device. With modern technology it would be only logical to have more than 5h on an device that was hundered of dollars
[Samsung Galaxy S9  Real Life Review] iSonik:
Yup this. I use Anki alot on my phone (like 1-2 h daily) so that already killed my S9 battery
[Samsung Galaxy S9  Real Life Review] dannotsys:
I was able to get 7 hours and 8 minutes of sot at 10% battery left, with heavy usage of youtube premium (8h and 15 min over 4G, most time watching videos, not just listening), medium use of google play music with bluetooth earphones (around 1h and 5min over 4G) and some gaming (10 min of Clash Royale). All this after disabling most of samsung bloatware (including Bixby) with the app Package Disabler Pro and putting the not used apps to sleep, by preventing them to use the battery when not active
[Samsung Galaxy S9  Real Life Review] realali:
I use phone 2 hours every day. on the way to work.
[Samsung Galaxy S9  Real Life Review] dadme:
What software/security patch? S9 or S9+?
[Samsung Galaxy S9  Real Life Review] dannotsys:
Galaxy S9 SD 845, the smaller one

But that was some time ago, with android 9 and latest patch for it at that time (ZTO CSC). Now with the latest android 10 patch, I cannot properly check the screen on time from the last battery charge, due to the changes on the battery stats screen, but it is surely above 5 hours (not much gaming, only clash royale)

I would recommend however always disable the bloatware using that play store app, disable the always on display feature, bixby and put some used apps to sleep while not in use

The samsung touchscreen is very smooty and sensitive but are a big battery drainer too, so games and apps that require constant touch can increase the drain rate
[Samsung Galaxy S9  Real Life Review] hulhulsulsul:
It is such a frustration that the battery lasts only half a day with 2 hours of screen on time. And my device is literally brand new. And i paid $490 USD for that piece of junk.
[Samsung Galaxy S9  Real Life Review] ungern:
2hrs SOT as brand new?

Either it's not new, you're playing games that are processor intensive, or battery is drained by background junk.

I bought a 2 year old S9, use dual SIM and easily get 2hrs SOT on a single charge playing medium draining games.

Test Accubattery, that'll tell you what's using the juice.

Tunein for example sucks it dry, really bad app for a simple task as playing radio.
[Samsung Galaxy S9  Real Life Review] hulhulsulsul:
Didn't have the chance to observe the battery life on Android 9.0, my phone updated itself to Android 10 One UI 2.0 right after I unboxed it. Therefore, I really don't know if it's software or hardware related. But I'm planning to downgrade to 9.0 to see if that makes any difference in terms of battery.
[Samsung Galaxy S9  Real Life Review] chaos_envoys:
My battery usage today

Been a busy day, and less time to use the phone, but overall great battery life for me
[Samsung Galaxy S9  Real Life Review] GONEzo:
Ok this phone is the most ****ed up battery.....First WEEK absolute crap battery life (2-3 hours max screen on time). Now, finally I'm getting over 5 hours. I do however have "intelligent scan" turned off and location off most of the time. Surely intelligent scan doesn't use that much battery? Like....WTF.
[Samsung Galaxy S9  Real Life Review] radiohead14:
day 4 - seems like it's settled, and got 7hrs sot (see attached). similar usage to my previous post.
[Samsung Galaxy S9  Real Life Review] stevenl23:
How??

I'd take a screenshot, but i'm attempting to fully deplete and recharge the battery because i'm gettig like 3 and 1/2 hours screen on time.

To clarify i've set permissions for locations to be for only google maps, i've left it on for find my samsung predominantly.

Is it because i have intelligent scan on?

I have the exynos variant and have had it since the 13th.:confused:
[Samsung Galaxy S9  Real Life Review] Swordchan:
Yo, the highest i can get is probably around 4 hours SOT and 24 hours on battery . I'am using apps like snapchat, instagram,facebook. Automatic brightness, AOD. Location on battery saving. . Is snapchat the battery killer? even tho it doesnt show that its draining much in Battery usage?

Can any1 using snapchat,instagram, and facebook reply and tell ur SOT / batterytime. cheers
[Samsung Galaxy S9  Real Life Review] ssgunner20:
Here are my results.

Similar on the S8+. So no complaints.

[Samsung Galaxy S9  Real Life Review] sl4y3r88:
My personal best on my 8 day old Exynos is 4hrs 20 mins. #fail
[Samsung Galaxy S9  Real Life Review] stevenl23:
-Get a dark theme

-i left on location for find my samsung, if you are like me revoke location access to everything even google maps except Google play services. Google maps tracks your location in the background otherwise. It'll just ask you for location access whenever you use it. Otherwise turn it off.

-Enable power saving mode only for decreased brightness. Don't down clock CPU and anything else unless you wish. Somehow this manages to help a lot with predicted battery life.

-Disable Facebook's ability to run in background.

At first battery life was terrible but even with a lot of gaming I'm getting very good battery life.

I have exynos variant

:good:
[Samsung Galaxy S9  Real Life Review] chaos_envoys:
That's the battery life for s9+ right? Not the s9..

[Samsung Galaxy S9  Real Life Review] radlink14:
Thanks a lot for your tips, I did the following:

Battery saver - only reduce screen 10%

Gps- battery saver option

Developer options - turn off the data always on even when on wifi

And it seems I should be able to get to 6hrs based on this usage!

I have the duos exynos variant.

[Samsung Galaxy S9  Real Life Review] WingedHussar:
Ah, yes. I did drop screen resolution to FHD+. I also set a dark theme. I'm not sure if it makes any difference l, but I use Nova Launcher. Lastly, under Device Management -> battery, I made sure apps weren't using too much battery in the background. Other than that, I don't use battery saver or anything. I have the unlocked Snapdragon version.
[Samsung Galaxy S9  Real Life Review] ja-ki:
So I got this phone today and I'm on my first charge. Right now it has 50% left and I got exactly 4h SOT. Exynos variant.

Edit: I'm now at 25% charge and got exactly 6 hours SOT

[Samsung Galaxy S9  Real Life Review] polmdm:
I have difficulties to reach 3 SOT, with your same phone (s9 exynos), can you share your settings?

I have all apps under control (except Telegram, Whatsapp and Fitbit), no Always on display but my battery drain more in stand by than using it... I don't know why
[Samsung Galaxy S9  Real Life Review] chaos_envoys:
Hmm.. my setting is

- fhd+

- developer options: mobile data turned off when on wifi

- screen brightness about 35% with auto on

- disabled facebook

- no AOD (doesnt use it that much)

- dark theme (but my wallpaper isn't though)

- apps are sleeping always except line messenger, whatsapp, google play games, spotify

Only that I think..

My usage today was even better

[IMG="exynos S9"]https://preview.ibb.co/bvnsSH/Screenshot_20180406_192517_Settings.jpg[/IMG]
[Samsung Galaxy S9  Real Life Review] polmdm:
Today usage, I have your same settings (except for developer one and auto brightness)
[Samsung Galaxy S9  Real Life Review] sprockettyz:
So what was your usage with the same. Settings?

I'm getting really poor battery life on exynos
[Samsung Galaxy S9  Real Life Review] polmdm:
Sorry I noticed only now that I couldn't share the screenshot:

Usually I reach 4 h SOT but only the days I stay all day covered by Wi-Fi, the others is a dramma. Another big problem I noticed that during the night (airplane mode) it lost about 15%....

The paradox is that the battery drain more when I don't use it than when I use phone. I've already wrote to Samsung assistence to notify this problem. I'll be waiting for further information instead I disabled some apps and I'm using a dark theme...
[Samsung Galaxy S9  Real Life Review] sprockettyz:
I'm getting similar drama on s9 exynos.
[Samsung Galaxy S9  Real Life Review] chaos_envoys:
The develper option setting to turn off mobile data when wifi is on really helps saving battery overnight when idle and on wifi.. on an 8 hours sleep, my battery drain was just 4%!!!

Didn't use airplane mode, wifi and mobile is still on and the battery drain is just 4%.. really impressed by my exynos s9 now

Seems like an app is draining your battery on the background.. what social apps you're using?
[Samsung Galaxy S9  Real Life Review] sprockettyz:
Are u syncing any Google accounts?
[Samsung Galaxy S9  Real Life Review] chaos_envoys:
Yeah, i'm using google account on calendar and contacts, and push service on my gmail.. not that much email coming in though..
[Samsung Galaxy S9  Real Life Review] polmdm:
Telegram and WhatsApp and Gmail in push. I have to check Google settings to verify the syncing... I'll do as soon as possible
[Samsung Galaxy S9  Real Life Review] edhahaha:
getting around 4 hrs of average sot for SD845 unlocked version, been using the phone for around 2 weeks, always on location, auto brightness, no AOD, anything more to pump out more battery life?

on side note is the android OS and android system usage seems about right? cuz technically from the graph it uses 10% or 8% of the battery and I monitored its around 8~10% for each everyday.
[Samsung Galaxy S9  Real Life Review] stevenl23:
Are you sure you are looking at screen on time? Not 'on battery'?

Cause i reckon that's kinda impossible. Max for me with exynos as well is 4 and 1/2
[Samsung Galaxy S9  Real Life Review] ja-ki:
The time the screen was on. Total runtime was longer of course. I will charge my phone fully soon and post a screenshot.
[Samsung Galaxy S9  Real Life Review] chaos_envoys:
that's my usage.. 6 hr SOT is achieveable for my exynos
[Samsung Galaxy S9  Real Life Review] stevenl23:
Somehow I managed to get this battery life while also playing downloaded music on spotify for over 6 hours. Exynos variant s9 too. Power saver mode only includes decreased screen brightness, not CPU limiter or anything else.

Anyone who jumped to the s9 from a v20? Would love to know the feedback.
[Samsung Galaxy S9  Real Life Review] chaos_envoys:
I switched from lg v20 to galaxy s9 exynos, the regular version, not the plus.. overall I really glad I switched, the device is easier to use since it's significantly smaller, the dual speaker is better, the camera is significantly better, the screen and the battery life is significantly better.. really miss the removable battery though.. but didn't regret the switch.

My battery life yesterday, full of gaming though
