Overnight Battery drain - Please Help

Hi guys

I'm using Exynos 6GB variant (Indian Version).

I have posted the screenshots of my battery usage overnight. I believe the drain is higher than usual.

Only Wifi, GPS and Sync are ON. Could anyone help me find out the issue?https://xdaforums.com/#
[Samsung Galaxy Note 9 Real Life Review] RedDevils88:
Today my standby drain is horrible. 5% per hour. Is this even normal?
[Samsung Galaxy Note 9 Real Life Review] alex989898:
No. 5%/h for a phone doing nothing is not normal at all.
[Samsung Galaxy Note 9 Real Life Review] AlfaM03:
I get 5h screen on time with my Exynos version which is okay. But I notice that I'm only pushing about 14-16hrs battery life, and yes about 2-3%/hr when I go to sleep at night. Is this normal? Is it because of the Exynos processor or probably some apps draining heavily on the background even of the screen is off? I've used greenify to disable any possible apps as well as adding almost everything to my always sleeping apps. Is there way we could monitor apps draining battery when screen is off without rooting?
[Samsung Galaxy Note 9 Real Life Review] themaximillian:
I also got Exynos variant and feel that standby drain is way to high...

During a 2h meeting I tested the standby drain using GSAM and had an average of 3.7%/h.

Android Systems has the main drainer.

Anybody got a suggestion on where to start looking to reduce the standby drain?

go to: setting-apps- android system- battery- allow activity in background- off

you can do this with several app system

and help with your power drain
[Samsung Galaxy Note 9 Real Life Review] vonDubenshire:
It's usually a router issue.

Check your beacon intervals and dtim setting s.

mine lasts 12 hrs of using constantly. SOT reaches up to 7 hours
[Samsung Galaxy Note 9 Real Life Review] mariojp:
I've just lost 13% of battery within 4 hours of standby at work. I don't understand this. This is a 4000 mAh battery!
[Samsung Galaxy Note 9 Real Life Review] jxb25:
Where do you go to find out if your phone has a standby drain
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
Use the following three apps. Accubattery Pro, GSAM and Better battery stats. These three apps will enlighten you.

[Samsung Galaxy Note 9 Real Life Review] 0alfred0:
Yes, I sold my S8+ last year because it was losing 15-18% over night and 3-5% an hour in standby. It is not a new problem (at least with exynos).

Sure, you could try to tweak 100 settings and disable all apps and all... but is that normal usage of a phone? No, sadly normal usage means high drain on Samsung devices. I really dont see a reason why i would buy a 1000€ phone with 8gb ram just to restrict apps to run in the background and have battery saver on all day (restrict the fast cpu, cut back on screen resolution - all reasons why i bought the phone) .
[Samsung Galaxy Note 9 Real Life Review] ehsanuetian:
is this normal?
[Samsung Galaxy Note 9 Real Life Review] SuckOr:
I would just tell Samsung the problem, so that they can work on a fix. There is something wrong.

Simply use the Samsung+ / Samsung Members App.
[Samsung Galaxy Note 9 Real Life Review] hatsku:
Hello guys I was wondering if 0.9%/h in standby is normal or not ? With LTE : on ,GPS: on sync: on, I have exynos version

And did someone notice that people have battery issue have the sm n960F model, will it be this model have battery issue ?

I also got a sm n960F model.

Thanks for your attention :)

Hi all

I have the same issue - my previous Note 9 from EE 128GB was brilliant lasted ages with 6 or so hours of SOT and a lot longer standby but my new dual sim from Samsung is just not making it.

I've tried almost everything the one thing I haven't tried is setting up as a new phone to start from scratch. Has anyone else tried this?
[Samsung Galaxy Note 9 Real Life Review] sefrcoko:
Users dedunitely shouldn't cripple their phones, but Sammy throws so much into the mix that a lot of it isn't needed for everyone. Turning off the things you don't use can easily drop the idle drain to something more reasonable like 1% or even less.
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
I don't have issues with standy drain or sot. However I've been running a few self experiments of late. I've been putting the note 9 in aeroplane mode for about 4-7 hours nightly.

Sometimes it drains 1% sometimes the usual 2-4% pretty random. What I learned? Aeroplane mode can still use similar battery than when not in aeroplane mode sometimes.
[Samsung Galaxy Note 9 Real Life Review] hkbladelawhk:
Standby drain is pretty terrible on mine too. If I keep all apps I need enabled, then it's like 4-5%/hour.

[Samsung Galaxy Note 9 Real Life Review] AndyCosmos:
Thank you , I just followed your advice by not allowing Android system run in the background and seem to do the trick , as for now the battery drain seem to be minimal , durin the night with medium battery saver with WiFi on and AOD OFF only 1% down during 8 hours overnight standby , have tge6 Note 9 for a few day and the battery was horrible , will report back more after a week . ( I also turn off bixby and good assistant voice activation off )
[Samsung Galaxy Note 9 Real Life Review] Sherlock H:
I can't do this on my S8+ , Android 7. Please help.
[Samsung Galaxy Note 9 Real Life Review] AndyCosmos:
You mean you could not find Android system in apps lust ? I don't know about Android 7 but if there is a 3 dot on the right corner when you are on apps list the click on it and choose system app ad back to app list and you will find the Android system , disbale the background activity from there when you click on it .
[Samsung Galaxy Note 9 Real Life Review] Sherlock H:
See this please in attachments. Where is it?
[Samsung Galaxy Note 9 Real Life Review] RanMN:
Just adding on to the thread that my Exynos 512gb is also draining around 10% over the night(around 6.5hrs). Dint have this problem the first few days.
[Samsung Galaxy Note 9 Real Life Review] AndyCosmos:
Here are some screen captures from my Note 9 ( 128 GB ) running Android 8.1 .
[Samsung Galaxy Note 9 Real Life Review] K-alz:
I suggest that you shouldn't stress about the 2% or 5% or even 10% standby drain. The phone has a ton of features and processes going on in the background. Also, I suggest leaving everything as is out of the box and your battery would work just fine. Samsung optimizes everything with the consideration of everything turned on. I don't have any problem with the battery on my TMobile note 9. It does drop faster from 100% to the 80s then after that it holds up real well. Between 6-7 hours of screen on time with everything on just like it is out of the box and QHD enabled. Make sure to reboot your phone once or twice a week. Also, clear the cash through recovery just as often. One more thing, Everytime you want to uninstall an app, make sure to go to settings/apps and go to that app and clear its cache and data before you uninstall it. If you just uninstall it, it'll leave wakelocks that will mess with your battery.
[Samsung Galaxy Note 9 Real Life Review] OutCastedSheep:
by doing this, will it affect any other background running apps to turn off??

(e.g) messages, notifications, live updates for some apps.?
[Samsung Galaxy Note 9 Real Life Review] mudrazr:
Battery drain weird

Hi guys I have been using the note 9 512Gb exynos version the battery drain during idle is almost close to 10% I find it strange. I have switched of all the background activity my aod wifi is on during the idle.
[Samsung Galaxy Note 9 Real Life Review] GrumGrum:
I've asked to return mine, its no where near as good as the 128gb I had and my wifes P20 is so much better, only thing I will miss is probably the Spen. Maybe Mate 20 X or Mate 20 Pro for me :(
[Samsung Galaxy Note 9 Real Life Review] illetyus:
I use accu battery app. It says %20 drain in 7 hours. It does feel weird. Is it normal?
[Samsung Galaxy Note 9 Real Life Review] speed8081:
Battery drain maybe some apps still running on the background. Try to ""closed all" to clear the apps after using.
[Samsung Galaxy Note 9 Real Life Review] akyp:
I used to get slightly over 1%/hr with data, WIFI and AoD off overnight. After wiping the cache partition it becomes 0.5%/hr which is a lot more reasonable.

Edit: Forgot to mention I have the Snapdragon variant with both SIM slots in use.
[Samsung Galaxy Note 9 Real Life Review] Icetea:
the German web side "inside-handy" has checked also the note 9 (SM-N960F-/Exynos 9810)

they wrote, that the note 9 normally has a power consumption of 0,56%/h in standby mode and 5%/h at normally work.

see here -> https://www.inside-handy.de/handy-vergleich/samsung-galaxy-note-9/huawei-mate-9 in area "akku"

i have compared it to my phone. (HUAWEI Mate 9) ;) and the shown values for my mate 9 are true! +/- 2% at 8 hours (in the night!) if BT/GPS/BGDATA/WLan is off.

But the problem is, that HUAWEi uses a own "doze" mode that sometimes killed app activities during the night! you can’t do anything against that circumstances!:p You have the choice! More power consumption against killed/frozen activities! :eek:
[Samsung Galaxy Note 9 Real Life Review] illetyus:
Mine eats %2 per hour......
[Samsung Galaxy Note 9 Real Life Review] Icetea:
At night or at day?
[Samsung Galaxy Note 9 Real Life Review] illetyus:
When i sleep, it drops to 0.7 per hour.

When i use the phone, it is about 2.7 per hour
[Samsung Galaxy Note 9 Real Life Review] Shadyville01:
If you have an Exynox version, switch your mobile connection to 2G only before gong to bed, garantee you a 1-2% battery drain overnight at most.
[Samsung Galaxy Note 9 Real Life Review] sefrcoko:
Pretty sure the chip already has thermal paste applied from factory. All it does is ensure uniform transference of heat from the chip to the heatsink. Adding more paste wouldn't help unless the existing paste had already worn away (meaning the chip isn't transfering as much heat to the heatsink as it could be, potentially leading to throttling due to overheating). Adding too much paste can also cause problems. Not sure why thermal paste was mentioned in the context of standby drain though.
[Samsung Galaxy Note 9 Real Life Review] sefrcoko:
If it wears out then the chip would overheat and get severely throttled or even shut down completely. Nothing to do with standby drain, and never happened once on any phone I have ever owned :)
[Samsung Galaxy Note 9 Real Life Review] sefrcoko:
Yes the processor will drain the battery... because it's being used lol. You're still mixing up things in terms of thermal paste and standby drain, which are very much unrelated. But Greenify is a valid suggestion, agree on that at least ;). Cheers

What the hell is talking about ? [emoji1787]
[Samsung Galaxy Note 9 Real Life Review] Tornlogic:
2 Full Days with 14% left

So here are my results of my Snapdragon variant after owning the phone for 6 weeks and not rebooting for the last one. What the image doesn't show is how much I stream music via Google Music and podcasts via YouTube Red. Usually streaming to bluetooth in my car, or listening to YouTube Red with headphones. So I may not have a huge amount OST, but the phone is under heavy use through out the day... or in this case, 2 days.

[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
I've come to learn that anything below 1% per hour battery drain in standby overnight is good.
[Samsung Galaxy Note 9 Real Life Review] Jpas1:
I've noticed nearly 2% drain per hour overnight with Bluetooth and AOD display on. Android system is typically the highest usage item when I look at my battery usage. Any recommendations?
[Samsung Galaxy Note 9 Real Life Review] vctrrl:
I've been experiencing the same kind of drain overnight without AOD or BT on. System is also eating relevant amount of battery. It was draining about 0.6% to 1% per hour previously. No configuration change and no new apps installed and it went to 2% or even more per hour.
[Samsung Galaxy Note 9 Real Life Review] sullytrny:
I've found that if you don't use the Optimization feature to ofen that the battery life will stay quite high, it's basically a cache cleaner and if you have a lot of apps music movies like I do (15,000 songs 50+ movies 50 games) it just rebuilds everything in the background for a few days
[Samsung Galaxy Note 9 Real Life Review] sullytrny:
But don't get confused with this, see attachment :cowboy:

It's the option at the very bottom
[Samsung Galaxy Note 9 Real Life Review] sullytrny:
With that enabled I'm getting 2% drop per hour while using surfing the net

Need some help guys .. just lost about 13% in the 8 hours I slept. I was on mid power saving and on wifi
[Samsung Galaxy Note 9 Real Life Review] stiffis:
Tried restarting the device and turned off WiFi over night? :)
[Samsung Galaxy Note 9 Real Life Review] Limeybastard:
Put it on airplane mode over night then report back.
[Samsung Galaxy Note 9 Real Life Review] avatar_ro:
can anyone please tell us how the overnight battery drain is on PIE?
[Samsung Galaxy Note 9 Real Life Review] dancrow:
Mine is 0.9% per hour
[Samsung Galaxy Note 9 Real Life Review] avatar_ro:
thank you. so basically the same.
[Samsung Galaxy Note 9 Real Life Review] benjaminllim:
0.6%/hr on Oreo, Exynos version.
[Samsung Galaxy Note 9 Real Life Review] sumukh_rao:
I have the Exynos variant and after updating to Pie, I have terrible battery drain due to Google Play Services. It's on the top in battery usage and I can't restrict the background activity. Any help?
[Samsung Galaxy Note 9 Real Life Review] Ulfrik:
Well quite the same here man... It is very disappointing about this phone.

I am suspending as much apps I can putting them in "always sleeping", have a slight improvement since then
[Samsung Galaxy Note 9 Real Life Review] benjaminllim:
After the latest update not Pie update, my standby became slightly worse from 0.6%/hr to 0.8%/hr.
[Samsung Galaxy Note 9 Real Life Review] bandario:
There is a magisk module called Universal GMS Doze that claims to optimize the ridiculous anti-deep sleep behaviour of Google Play Services whilst still letting important things like calls and SMS pass through uninterrupted.

It's early days yet but I am getting spectacular battery life given my battery is less than a week old and not even close to max performance yet.
[Samsung Galaxy Note 9 Real Life Review] Krishan Shamod:
I have same problem.Please report it to Samsung.

---------- Post added at 06:09 PM ---------- Previous post was at 05:41 PM ----------

In standby time my note 9 battery drain fast.

Ex:- last night(11.00pm) my battery has 33% battery but today morning(7.00 am ) it has 20% percent.
[Samsung Galaxy Note 9 Real Life Review] bandario:
Are you using always on display?

Do you have exynos version? There are things you can do.
[Samsung Galaxy Note 9 Real Life Review] Krishan Shamod:
My AOD turn of on 10pm .Its not working in mid night.I'm using exynos version.
[Samsung Galaxy Note 9 Real Life Review] Krishan Shamod:
What are that things?
[Samsung Galaxy Note 9 Real Life Review] Krishan Shamod:
I found the problem.If you are turn on Bixby voice wake up battery drains very fast in standby time.turn off it and check battery life.

I had same problem but after I turn off it my note 9 drains 2-3% in night.....
[Samsung Galaxy Note 9 Real Life Review] bandario:
Custom rom, custom kernel, power tweaks that require root, greenify via root or xposed module. Every little bit helps to build a battery monster.
[Samsung Galaxy Note 9 Real Life Review] Krishan Shamod:
How I do those??please help???
[Samsung Galaxy Note 9 Real Life Review] brooon:
Hey there!

The battery drain indeed seems to be horrible on PIE (exynos). I´ve made several screenshots and obviously (as read several times on the net) the android system as well as the kernel are the main suckers here. I honestly have no idea what to do.

Standbydrain (Airplanemode) :

1-2% in 8-10 Hours.

Its sleeping like a baby.

But only on Oreo 8.1 ! On Pie its daining 4-6% in 8-10 Hours.

If you guys want Screenshots : 2 more Days and i can uploade some ;)
[Samsung Galaxy Note 9 Real Life Review] johngerges582:
After the Pie update, my battery life tanked.
[Samsung Galaxy Note 9 Real Life Review] doggydog2:
2.5%/hr is the minimum i could get when standby on 3g. With sysconfig patcher, naptime, servicely and friendly kernel. Not happy at all with battery. Can't do more than 18 hours ever. Add some 5-10%/hr SOT and it's dead quick. Also when restarting or flashing there's like 10% drop each time during that 5min operation.
[Samsung Galaxy Note 9 Real Life Review] bloodstorm666:
Same here.

android core apps battery drain

draining my battery like crazy. anyone has a fix?

done all the wipe cache, data for related apps still the same.

i have alot of contacts though. will this be an issue?
[Samsung Galaxy Note 9 Real Life Review] amorosa:
Hmm do a force-close of the app.

Then restart ur device and see what happens in future with core apps.
[Samsung Galaxy Note 9 Real Life Review] sherpa25:
What app is that you're using to view app consumption ('App Sucker'?)?
[Samsung Galaxy Note 9 Real Life Review] brooon:
Hi there!

Draining mine as well. I get roundabout 3-4 hours OST, sometimes way less.

gsam battery monitor

you have to use adb command to enable stats like the photo i have.

---------- Post added at 03:05 AM ---------- Previous post was at 03:04 AM ----------

EDIT: i did a factory reset and reinstall everything from scratch (not even restoring settings) and android core apps seems to be fine now.

hope it doesnt come back again and my battery improves.
[Samsung Galaxy Note 9 Real Life Review] johngerges582:
I gotta say after about 2 days after the update, my battery life is now better then ever. I have no idea how. Disabling WIFI calling, and disabiling the lift to wake really improved it for some reason.
[Samsung Galaxy Note 9 Real Life Review] DarthJe5us:
Lost 20% in 2h last night while my phone was in my pocket. Pie is so bad for battery for me.
[Samsung Galaxy Note 9 Real Life Review] avatar_ro:
What the actual F!!! since the last update I lose on mobile 4G dual sims around 2.5%/h which is horrible., however with WIFI ON only 0.7%
[Samsung Galaxy Note 9 Real Life Review] Kimbo82:
Last night I lost 1,1% per hour, deep sleep for 83% of the night. If I leave the phone with airplane mode on, then I lose around 0,1% per hour. I'm disappointed with the high drain in standby mode...
[Samsung Galaxy Note 9 Real Life Review] avatar_ro:
I have already complained via Samsung members app a few days ago. I am waiting for an answer if I will receive one.
[Samsung Galaxy Note 9 Real Life Review] Kimbo82:
Let us know what they say. It's ridiculous I think...
[Samsung Galaxy Note 9 Real Life Review] carloandreaguilar:
Im one One UI March patch and I only got 2% drain in 8 hours of sleep with lift to wake on, and wifi and data on. No airplane mode.

Aod was on tap to show.

I just got the phone 5 days ago

Amazing standby. I set battery hog apps to sleep automatically when in background. Never had such
[Samsung Galaxy Note 9 Real Life Review] Kimbo82:
As it should be, I wish I had the same. Frustrating that I don't have it...
[Samsung Galaxy Note 9 Real Life Review] brooon:
Flashed a fresh Rom via Odin with newest updates (CSC3 - - > CSC1), didn't load the samsung / Google backups during the setup process and installed just the basic, most important apps (Google stuff, outlook, slack). This is the last chance for this device, else I'll sell it.

/shrug
[Samsung Galaxy Note 9 Real Life Review] avatar_ro:
normally it should drain a max 1%/h when not used but this is not the case. ideally would be 0.5%/h but we can only dream. (for dual sim I mean)
[Samsung Galaxy Note 9 Real Life Review] carloandreaguilar:
You need to Install wakelock detector lite and see what apps cause drain. In my case it was Skype. Put all battery draining apps on restrict mode. That's all. Check wakelock detector
[Samsung Galaxy Note 9 Real Life Review] nuclearrage:
I took off charger 5 am Friday morning. It is now Saturday 9 am, I am at 68%. This damn phone sleeps better than I do. I probably wont charge again until Sunday night.

Bone stock. AOD is always on, so I guess I am lucky as well. I have a direct from Samsung unlocked US model.
[Samsung Galaxy Note 9 Real Life Review] brooon:
Well...things got better with CSC1.

Exynos.
[Samsung Galaxy Note 9 Real Life Review] carloandreaguilar:
I've also turned off NFC and bluetooth
[Samsung Galaxy Note 9 Real Life Review] avatar_ro:
Of the answer was a typical one, go to battery settings and put to sleep apps that I do not use... yeah... top quality right there.
[Samsung Galaxy Note 9 Real Life Review] Kimbo82:
I chatted with support here in Sweden as well, and I got the same answer. Like I hadn't tried that and I think a phone with this battery should have good standby drain by default...

I went to Oreo for now, and I'm quite happy with the drain now. I feel that it's much better, and I like the theming options. I will monitor to see how the updates go and later on I might go to Pie again.
[Samsung Galaxy Note 9 Real Life Review] horiakyys:
I went back to Oreo too, but unfortunately I lost10% of battery in 1 hour, with light usage... A little bit strange, I remember battery was better. But I'll see after few cycles, maybe will get better
[Samsung Galaxy Note 9 Real Life Review] brooon:
Back on Oreo as well. I really start to miss my 3T - it just worked from day one :D
[Samsung Galaxy Note 9 Real Life Review] mohammad.nomaan:
I have been using the device for over a week and looking at the battery life, its isn't as great as it should be for a 4000Mah unit

To get a better backup, I disabled all the useless apps and sensors but still the device doesn't give 1 day and need to be recharged

Strange for me
[Samsung Galaxy Note 9 Real Life Review] melchiar:
