Battery Drain on 9.0 Pie - Samsung Galaxy Note 9 Questions & Answers

Hi people,
Can someone give me and opinion of the battery drain with a note 9 on pie?
I bought my Note 9 four days ago and updated to 9.0 pie right out of the box, I think that battery is still optimizing for usage but I find it very bad with battery life and SoT. I'm posting a screenshot, if you have some tips ?

I'm with exynos, 50% brightness display, exynos version, Bluetooth off

You answered your own question! Battery is still optimizing for usage! You have to give it 10 or so days before it battery gets better! Also turn off Wi-Fi, Bluetooth, 4G, Sync, turn the screen off turn everything off lol messing with you 2/3 weeks mine took to settle down!

I'm having the same problem. Android System was waaaaay lower before. It's always at the top of the list now. :/

There's plenty that can be done, especially if you have the exynos version of the phone.
-Unlock bootloader and install Dr Ketan's rom, it is fantastic.
-Then apply endurance kernel.
-Use Magisk manager to apply module: Universal GMS Doze
-Use Mtweaks to apply a few kernel tweaks
I haven't gone this far just yet as I'd like to see how the phone goes without it for a few weeks but you can also install greenify or if you want to really get serious, greenify xposed module. Personally I find the battery life of the note9 to be fantastic but you must keep in mind that the screen is enormous and hi-resolution. Whenever you are using the screen, especially at a high brightness level the battery is going to drain - it can't run on good intentions.
Try turning down the brightness. If you are absolutely serious about battery life over everything else, you can disable auto-sync, remove the official facebook apps if you have them and replace them with faceslim and lite messenger and modify the notification settings.
Doing all of the above and only turning the phone on when you need to make a phone call or use navigation etc should net you an easy 4 days+ of useage but then again, you may as well have bought a $30 powerbank phone.

Tripping Knox hardly sounds like a good idea if I'm honest.
If your Android System is high then something in the background is wrong. You could try clearing cache then give the phone a couple days to settle

Battery life varies significantly with any phone and any version of Android.
Often we assume, wrongly in my opinion that a very large factor in battery life is the version of Android , hence the numerous posts on this forum who wish to or have gone back to Oreo, for reasons I consider delusional.
What apps you have on your phone and how often you use them are significant, playing games that use lots of cpu and gpu is going to impact battery life.
Web browser and YouTube rather less so.
I have experienced lower and higher screen on time and standby time with the same apps and version of Oreo, and Pie (both on beta and released)
I am on Exynos Note 9
Bought and used since release date Aug 24 2018, haven't used so called battery life friendly charging (20% to 80% etc)
Can run battery down to 0% on occasion and charge to 100% using fast charge, often left on charge overnight.
Yes there are some optimisation that may help and I use a few, I couldn't tell how much they help though as just varying usage is a greater factor in my opinion
Battery performance from yesterday
18.5 hours total usage with 9.25 hours screen on time

Screen Brightness kills battery more than you'd think

So the poor battery life on my Note 4 might have more to do with screen brightness than I would have expected. Unfortunately, most people posting their SOT's aren't doing it in a very scientific way, so it's hard to know what we should expect from these devices.
Here are my battery test results using PCMark for Android https://play.google.com/store/apps/details?id=com.futuremark.pcmark.android.benchmark
In one test, I put the screen brightness to 100% and the results were pretty dismal. In the second test, I ran it at 50% brightness, which is brighter than the Note 2 at full and the results were much better.
I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

thanks for tests im using my exynos version on auto brightness and generally get 6 hours SOT. i saw on alot of people s stats and people who has problems generally has google play services on their battery usage list and it definetly shouldnt be at there... its probably about location reports to google every1 should disable it from location settings it doesnt break anything.

Yes, location can be an issue, but I think that impacts standby time more than SOT. Currently I've done the following to help with location-related issues:
- used lion tamer (soon to be called amplify) to slow down NLP wakelocks.
- set my location settings to powersave mode
- setup AutomateIt to turn on GPS when I'm in Google Maps (I'm usually plugged into the car outlet, so battery isn't a concern while navigating.
- Greenify stuff like Google search, Maps and several others.
I like and use Location Reporting, so disabling it outright isn't an option. My standby usage is very good at usually less than 1% an hour and my wakelocks keep my device awake usually less than 6%, but I'm still working to lower that number.

last night with 10 hours sleep time. with wifi connected sync was activated for 3 mails. i just lost 2% and i didnt do anything special like you did. no greenify no root nothing i couldnt even install wakelock detector cuz its broken on kitkat without root.
. i just disabled some useless stuff like samsung store etc.. everything else is working. and on my car i generally listen music over bluetooth
Lux could help

Before I started tweaking, I was getting around 6%-9% drain PER HOUR! Disabling stuff without root only got me so far, then the xposed tweaks and Titanium Backup had to be used.

like i said i dont know whats wrong for some people its probably something you installed(skype maybe) or mostly about location reporting. even last night i left my phone at 90% when i get it this morning after like 10 hours it was on 88% like i said earlier wifi was connected no power saving etc just normal idle time nothing special.

I was testing without any apps installed (just whatever I used to record battery consumption) and it was crazy high. Then I started adding accounts and apps, tweaking and I got my standby time to be much lower, but SOT leaves much to be desired. I'm going to try using the manual brightness and see if there are any differences - I often find auto brightness to be too bright or too dim! No "sweet spot" found! LOL
Greeny can also help but may need root
I'd suggest changing the settings for your Battery Monitor Widget app. AFAICS it polls every 10 minutes so a wakelock occurs every ten minutes to save the data. Use something like an hour and see what happens. Also would highly recommend BetterBatteryStats, a free version is available here for members.

I'll try that, although that might only improve wakelocks, not screen on time.
BBS never worked right for me. Always complaining that it couldn't retrieve the stats or falling back on something else.

Wait, with the screen off? Then you have something horribly wrong with your device. Mine did a few % over a night. With nothing done to the phone to conserve battery at all. Snapdragon, though. With the update.
I loose only 2% for 7h of standby last night.
We are seeing a trend I think, I noticed that it's mainly us 910U users or exnyos users complaining about battery life. So it must be something in the 910U rom?
I've got a 910F and I get 6 hours screen on time maximum :/

Doesn't happen now that I've rooted and applied my standard tweaks, but I tried a factory reset to see if I could correct the high standby drain and was not successful without these tweaks.

I have 910f and i got same issues with my batt.
i've tried clean system, root, custom rom. Battery is always draining higher than some people.
As i said in other thread: some people have an issue, some have great battery life. And nobody knows why
Maybe it's the guys who keep it stock and don't root, custom rom and "tweak" that get the good battery life.
Delete it pls.

[Q] Battery Drain Rate - Is this normal?

Hello, I have just a got an XT1254 for around a week so I am still testing the device. Battery is always my biggest concern for every phone I had and therefore I like droid turbo's big battery.
After I have got the device, I tried to debloat most of the moto/verizon/amazon apps and managed to get only 1%-2% drain during sleep overnight. I haven't installed many apps at this moment, as I am testing how long I can get with minimal usage for one charge. It is now more than 2.5 days after charge and I have 62% left, and I disabled almost all censors. and only turn on data/wireless only when necessary.
My problem is, I still get a, I think, quite fast battery drain when screen on. I am not watching video or playing games, I just use whatsapp or test camera, not even facebook, and I get 1% drain in 2-3 minutes. What I want to ask is, is this normal? Or is there anything I can do to reduce further? I think the screen eats most of the battery, and I used auto brightness, or manually to 10% brightness indoor, with dark wallpaper in launcher already.
I have no plan to root at this moment, but I think the processor speed can be lowered. Is there anything I can tweak about the processor?
Thank you very much for answering!

Thank you and I have tried to read the posts. The google play service doesn't seem to be the problem of my device. The drain during sleep is somewhat acceptable, and anyway I need to keep background data on for play service. My problem is, when screen on, it drains 1% in 2-3 minutes doing simple tasks like whatsapp and camera, and the brightness is already either auto or minimum. And my point is, given the huge battery and nothing serious being done, it still drains more than my previous phone (sony m2 also running kitkat 4.4.4)

You should take a look at the apps you have installed, besides this, I think the drain is pretty normal for a QHD screen. Remember there are great number of pixels to move in this screen, so the battery also suffers from this.

I attach a screen capture of my battery screen.
My phone is new and I haven't installed many things. Just nova launcher plus some widgets. BTW, may I ask whether phone idle contribute 25% of power is normal. Yes I mostly leave the phone standby and actually do not have real use except phone, sms and whatsapp.

I don't see anything wrong with the drain, all is perfectly normal. Phone idle is on top when you don't use the phone, so I think you have no problems at all.

Very disappointed in OP3t battery life. Not sure what to do.

I'm coming from a OnePlus One. Unfortunately, I can't find reliable BLP571 replacement batteries in the U.S., so I purchased a new OP3t.
On the OPO, I have been running custom MM and N-based ROMs. When the OPO (currently running Nougat 7.1.1 on TugaPower 2.1) is sitting around doing nothing, I typically see my idle battery current drain at around 9 uA to 14 uA and Wakelocks around 10%. Of course, when I turn the screen on, these jump up.
On the OP3t, I have tried running both OOS 3.5.4 and the new TugaPower 4.0 (which is based on Nougat 7.1.1). When the OP3t is supposedly doing nothing, I saw an idle current of around 85 mA on OOS 3.5.4, and around 35 mA on TugaPower. I didn't check the Wakelocks on OOS 3.5.4, but the Wakelocks on TugaPower are around 93% awake time (!!!!).
When I wake up in the morning, the OP3t is down to around 75% battery. For reference, my OPO used to be around 98% overnight when the battery was new. Even now, my ancient OPO with a nearly useless battery is around 85% for the same overnight time period.
What can I do?
3.5.4 actually has drain issues, try 3.5.3
Even after the annoying wake-locks and the random battery drain that just happens because why not... I still manage to get 5-6 hours of SOT, I have managed to push it till around 9 hours if I keep the Bluetooth and data off; with Greenify and using the aggressive doze it has helped but I don't get any notifications until I turn my screen back on.. Which is fine with me, as I get texts and calls. It's much better than the nexus 6 and the galaxy s4 which would struggle to even get 4 hours of on screen time. There are plenty of people raising issues about battery life on the OnePlus3T even though its probably much than your last device. XDA also has plenty of threads already created talking about the same subject.
Edit - I'm on the latest nougat update 4.0.1
the 3T or OOS doesnt have any drain or bad battery issues.
the problem is user/user-app based.
sort out the app which is causing the problem.
I just made a post to a similar thread. It seems the battery issue is hit or miss. At any rate, please check my post here: https://forum.xda-developers.com/showpost.php?p=70581453&postcount=9
Let me know if this helps you out. Look forward to feedback.

You stole my thunder.
Just kidding, but you're absolutely correct. I'm waiting to get my OP3T and then I will write a tutorial for users to help them out with the battery. Those 2 apps will be in my tut along with a few others that are helpful!
Weird, usually my phone, while idle of course, drains by 1% every 2 and a half to 3 hours. During use while im not playing games or anything im using pixel filter. Most time ive gotten is 9 hours 32 mins screen time. Im on 4.0.1 not rooted. Just uninstall apps u dont really need like amazon, youtube, facebook, tumblr and so on and use Firefox web browser. Firefox has background play for YouTube or any other audio source so you can stream music on Spotify soundcloud or whatever you want. I basically rely on Firefox for all internet things as if my phone were a PC. Saves time and battery because with 6gb ram my browser never slows down or reloads. Firefox is also really nice in the background consuming only 10mah every hour when not active or streaming audio. Cutting down ur app count will allow your device to doze longer, fetch less data and it certainly drains far less. Also if you're into this sort of thing, boot times are much quicker too.
Edit: sorry for the unedited massive paragraph here.
Another Edit: Make sure in case you want to use battery saver mode while streaming music to toggle Firefox to have unrestricted data usage in the data saver menu.
Check the link in my signature. My drain wasn't quite as bad but might help you figure it out. Good luck!
Thanks, guys! Greenify + ForceDoze seems to be helping a LOT! I'll need to let it run a few days to see the the real-world numbers.
I am having a problem adding apps to the ForceDoze Whitelist, though. Is that a known issue?

I've found that the whitelist appears blank until you add or remove an app, then the whole list will appear.
For me at times something appears to kick in in the background causing the CPU to spike and the phone to heat up. I can't figure out what it is though. When this isn't happening the battery drain is virtually zero and the phone flatlines overnight ,when it kicks in,the battery loses about 10% an hour on idle. I think there might be faulty drivers or something in the ROM causing this?! It's not apps as it happens to me on a completely debloated ROM with no apps. This is on Lineage and OOS. I've never seen this before on the phones I've had.

OOS 4.01 - I am experiencing exactly what you describe at 12%/hr and I have done literally all of the suggestions here. I have greenify, force doze, turned off location, disabled swift, did a factory reset and installed only 1 or 2 apps- and still I can watch battery drain with:
4 hours off charger and down to 44% with:
Kernel (android OS) 42.5%
Android System 33.7%
Google Play services 2.4%
Blah...Blah... (much smaller %'s)
What the heck could be causing this kind of drain? It seems to flatline when not in use for a while...
thoughts? Love the phone., but it is not usable like this....

Hello,
I usually use Greenify Paid Version + Amplify Paid Version but only in 6.X roms in 7.X Xposed isn´t released yet....
Do you recommend use Greenify + ForceDoze (I never heard about this app) even without Xposed?
Thanks in advance.
I am still struggling with battery performance on my new OP3t.
I am running TugaPower N10 (LineageOS 7.1.1) + Better Battery Stats + Battery Monitor Widget + ForceDoze + Greenify.
While my wakelocks seem to be pretty short now, my lowest average current drain is 35 mA. For reference, my old OnePlus One had a lowest average current drain of 7 mA, or about 5x more on the OP3t.
My battery meter reflects the higher drain.
I have the same apps installed, maybe even some less.
Looking for more assistance ...
I'm on 4.0.3 OOS and using Franco kernel, 2% drain during all night, 5 hours of screen on time and still 56% battery, check what is wrong with your apps, or move from Lineage to OOS, is simply better.
EDIT: I'm not using any app like ForceDoze or Greenify
I'm not dissapointed.

Android 10 One UI 2 Battery and Performance

for those who got the final update, or had the beta, how is the battery life and general performance compared with PIE ?
Mine is snappier and battery life is better.

The battery life is slightly increased and rest every thing is okay.
Was a beta user. Exynos variant. Im sure the battery life and performance of Snapdragon variants would go more better. Exynos always sucks.
I think battery is better, lets see the rest
Mine is about the same. In the beta forums it seems to be all over the place though, some are happy, some not so much.
Any changes in the camera quality ?
My Exynos S10 used to reach 30-40+ hours of battery time on P (mostly web whatsapp and regular phone calls, no games at all, see pic).
After upgrading to stable Q, juice can't even give me 30 hours. As I see it, in my case Q is clearly the culprit.
SOT is not a valid metric for me, as I'm always on web whatsapp -- lots of use, no screen on.
Stable version of Q. Better battery for me
2 hours of screen
It takes me 2 hours of screen. plz heeelp

For starters, try and disable the following settings, case they are on:
. location
. bluetooth
. AOD
. NFC
. WiFi (case mobile data is suitable for you)
<Display>:
. set screen brightness to something around 50% (middle of the bar).
. set <Screen timeout> to , say, 30 seconds.
. set <Screen saver> to "none"
<Device care> / <Battery>:
. set <Power Mode> to "optimized"
. set <Adaptive power saving> to "on".
As for apps, Facebook is known to be a huge juice drainer.
Let me know how this works for you,
Cheers

Disabling everything isn't the solution.... Something must have gone wrong during the update process. I have everything on and I have a great battery life. Maybe trying a factory reset for example (even if it's annoying)
battery is marginally better on mine, after the update i entered the stock recovery and wiped cache, i dont know if that does anything.One UI 2 is very underwhelming, not many changes

Disabling everything is for quick diagnosing purposes, for identifying shady component(s), not meant to be a solution. Think of a box that won't start. You start by ruling out PSU, then memory modules, video card, and so on. Sure, in the OP case update issues must be considered, as well as third party software.
Cheers
My phone feels great after the update. Fast and smooth, the battery is the same, gets me through the day with Wi-Fi,BT and mobile data on all the time.
Love the new animations but the gesture navigation needs improvement, especially when switching between apps. Overall great update.
Thanks you Samsung!
ram usage increased too...
I agreed. I'm on the stable version of android 10. I have a Galaxy S10 G973U and It is on T-Mobile. Battery Life has steadily gotten worse for me starting from the October security update and it is much worse on One ui 2.0. Overnight, I lost 15 PERCENT CHARGE. I don't know what to do. I'm not sure if its a problem with my device or a widespread issue and just a problem with the software. Pls help. I called samsung to report this 3 times and they referred me to a repair shop. I don't want to go to the shop unless I am hundred percent sure that this is an issue only with my phone. g973u1 users are reporting excellent battery life and some g973u users are reporting bad battery life. Pls help.
In only 2h of screen time, I've lost 40% of my battery and I was a 100%.
Few web browsing and some texts and Spotify playlist in the background.
Is there anyway to optimize the battery life on One ui 2.0?
Gotta love these "how's the battery life?" threads.
Mine is better.
Mine is worse.
Mine is about the same
Camera quality decreased
Phone runs hotter
Uses more ram
It ruined my marriage
The phone got bigger for some reason
And so forth...
For me its about the same
Hi. as I get the view of the battery life as it was in android 9¡? While still not understand view of the battery life in android 10

Question Critical battery drain

Hello
Yesterday i had the phone around 65% at 01h00, in the next morning (around 7h20) i wake up to find the phone at 1%, no wifi/4G/bluetooth/GPS...etc was active, even the battery saver was ON. As you can see in the screenshots, android system drain battery around 400% !!! what's up with this behavior ? happened the 1st time last week (49% drained in 8 hours) the problem seems gone after i fully charge and than reboot, but still today happened.
The phone is almost 1 month old.
The 1st few days, i disconnected the phone from charging at 100% and went to sleep, after 6 hours battery is drained by 6% without doing nothing. is this normal ??? screenshot
ROM : crDroid 8, latest magisk installed+microg+magiskhide props config and fdroid/aurora modules installed.
Thanks

clearly something is going wrong, I would suggest factory resetting, and optionally reinstalling your custom rom.

well, that must a bug related to optimiztion of the rom, report it to the rom mantainer
Exactly what happened to me same ROM same phone but I didn't root it. it drained from 54% to 6% during the night, next day I switched the ambient display off and the battery became better but so far I am also looking for solutions to make it similar to miui
I feel the battery is draining so much fast when I start using the apps unlike miui but the room is also great and fast , with my light use it gave me 1 day of use and remaining of 10% with 120 fps (3.3%/hr screen on and 0.6%/h screen off )
today I will test it with 60fps

No, only when charging of course (around 40°)

I'll wait and see if this bug happens again as right now i need the phone for the rest of the week, if happens again i might switch rom altogether on the weekend.

Wow, 3.3%/hr is seriously impressive for active drain, especially for 120hz. Can I ask you if you did anything special / your exact setup? I installed Ricedroid 8.0 + Sleepy kernel and applied the GMS Doze module + Naptime (as suggested by a kind poster on here), and this allowed my idle drain to go down to 0.2%/hr, but my active drain is still struggling a bit.

to be honest I am not sure if I report it correctly I have used accubattry app but I will post few screenshots from the app and you can see , I didn't do anything except disable the ambient display maybe my usage is light in default I don't know I also formatted the phone like 20 times during my testing for different ROMs. I found Cr-droid to be the best so far or miui

Ohh the 3.3%/hr is combined use, which takes account of both active drain and idle drain (through what I guess is some weighted average). But honestly, 6.7%/hr (or even 7.8%/hr tbh) is still pretty damn impressive, so I'll thank you for letting me know! Now I wanna flash crDroid haha.

I spent 1 day and half trying all custom roms in this forum because for long time I was on miui and didn't know how custom ROMs are now , after trying I found that all custom ROMs either are pixel flavored or very basic without any customization and I settled with Cr-droid because it offers best of both worlds less google and good customization options.
now regarding the battery after few days of using on 60 fps I have combined use 2.4%/hr and 0.8% screen off but I still feel that it drains fast during my usage compared to Miui , I have only used naptime for optimization do you advise me to add anything else for non-rooted device ?

MIUI very often switches off alarm (not clock alarm) and wakeups -- it's known for long. Your notifications often comes late when using MIUI. In real life situation, however you might never notice it, but it's there. It also sets higher priorities to known messaging, social media apps to receive notification/action faster than any apps that are outside "the list".
It's a good trade off for battery life compares to stock AOSP or lineage which put every apps on generic list of "optimized battery" based on your pattern. It will took a long before the pattern is useable.

I'm not sure about your possibilities on a non-rooted device honestly. I think Naptime can work on a non-rooted device, if you grant a few permissions through ADB first (if I remember correctly, the app itself will guide you through the process). Be mindful of which apps you're restricting though, as Naptime will likely cause delays in the arrival of notifications. You can whitelist apps through Android's battery restriction screen.

yes I am it currently after activation via ADB it made some improvement I felt , so far the highest consuming system apps are : Android OS [19%] screen [9%] and System UI [6%] can I do something about them ?

Hmm I don't have any further tips honestly, not about these specific things. In my case, using Naptime already improves battery life by a ton over the course of a day (not wasting entire %s in hours of idle time is already huge).
Try and see if greenify or its replacements helps.
