Poor Note 8 Exynos Battery Life? - Samsung Galaxy Note 8 Questions and Answers

Hi guys, has anyone else been experiencing poor battery life in the stock note 8 oreo rom? I've factory reset, switched off AOD etc. Same apps installed as when it was on nougat.
Thanks

Mine is doing the same. I reckon it will take a week or two to level out

i agree mine used to do that on nougat

I also have terrible battery life.
I've switched AOD off, as well as the weird Gallery settings (like Image Analysis etc), but it's still losing 30% battery while sitting idly for 3 hours.
I hope it does level out soon enough.

Maybe some of those apps aren't as optimized for Oreo yet. In any case, let it settle for a while after a major update like Oreo. I got over 5 SOT with my regular usage (27 hours runtime) on my first full charge after updating. Not bad, but it will improve a bit from there on my next 1-2 charges and hit 6 hours SOT like before.

I recommend you install betterbatterystats, give it permissions through adb, and let it run. Post some screenshots from the summary, kernel wakelocks, and partial wakelocks tabs. It'd make it easier to pin down the issues.

Okay guys, so it is the third/fourth day now and battery life has gotten better. This morning I did wake up to a bixby update, so maybe that was the issue? Anyways hopefully the battery life stays like this ongoing.
As soon as OEM unlock comes up I'm flashing a custom ROM ;P

[Q] has anyone upgraded to the official lollipop?

I've heard mixed reports regarding the latest ota update, some users have complained about the battery running dry in a much shorter time others reported apps crashing much more frequently. What do you guys think? Have anyone upgraded? Share your experiences please

I do not know about the OTA update, but I think the cause of the battery drain is more due to the applications installed on the device. For example after I upgraded to Lollipop (MaximusHD) my battery was draining ridiculously fast. Turns out it was the Gmail - INBOX application which was causing it. I would suggest clearing your device and checking the battery. Then slowly adding applications and testing it. Will definitely help you figure out the cause of the drain. Cheers.

thanks man, I think I'm gonna do a full reset after upgrading. should fix everything.
so your battery is now lasting more than it used to with android 4.4.3? I'm asking bc I've heard that android lollipop it's more battery friendly u know.
Well it has improved. But not drastically!. . Though I should mention my device is 2 years and a few months old, and I haven't really taken good care of my battery. I charge it overnight nearly every other day. But taking all that into consideration it gives me oddly 12 hours with normal usage. And 6 hours on a heavy day!
Used to get around 6 hours on heavy usage and 9-10 hours on moderate usage when i was on kitkat !! .
How do you like lollipop so far?
I have upgraded to Lollipop (5.0.2) and generally it is fine. Battery life is about the same, speed is also about the same.
I do have a question for anyone who has upgraded.. have we lost our ability to use the "Ok Google" Call command? It used to work on Kit Kat but now it comes up with my password prompt (pattern lock) before the phone dials out. I use this occasionally when I am driving.
Is this a new security measure in Lollipop or am I missing a setting on the phone?
Thanks in advance.

Stock Marshmallow Battery Life: What gives?

So got my father a S6 and its running stock Marshmallow, Long story short his battery life dies extremely fast. He has wifi turned off and bluetooth on most of the time. He has the phone on his pocket or on a desk not being used and the phone goes from full to 20% in a few hours. Should I flash a rom to help the battery performance or do you think its a faulty battery?
I Would provide screenshots but I dont have the phone on my at the moment.

Was the marshmallow just flashed if so might need to let the battery and kernel set in some scenes screenshots or stats would help determine if its a faulty battery

I ended up flashing back to factory using samsung smart switch, gonna give it another test tomorrow with minimal apps installed and if it drains then i know its a bad battery.
try wiping cache or factory reset in stock recovery. my phone had minor bugs after I installed 6.0 using Odin. factory reset fixed them.

ill try doing that thanks!
My battery life has actually improved since the update.
Make sure NFC is turned off as well (unless you use it often)
My battery life on MM isn't all that bad.. It gave me my first report on the apps that use the most juice, and gave me the option not to have it run in the background.. Not a bad feature.. Mine is rooted with a ton of Apps Frozen or Removed via Titanium Backup.. Battery life isn't better, but over time the device will get to know your habits and battery life should get better over time..
I'm stock MM and rooted running DS Battery Saver with the slumber profile. I'm just settling into it (a day or so) as well but out of the gate it's not too bad (12+ hours per charge). I've got most of the Tmobile and Samsung apps frozen but run a good dose of others.
I'm inclined to think this will improve over the next couple/few days and even more so with a custom kernel.
Update:
So I flashed the phone with samsung smart switch and battery is much better
Not as good as other phones ive used but its much better than what it used to be.

Root it an install deep sleep battery saver if that is an option.
If not, you can install an app like Greenify or Macrodroid and use them to disable sync or data/wifi when the screen is off.
That will help conserve battery quite a bit.
yes thats my next step. Its my fathers phone not mines. Just got my G5 today

Terrible battery life with nougat update

Hi recently just updated to nougat and did a clean factory wipe (stock no root) and my battery life is terrible. Is it normal? It drains so fast throughout the night that I lose about 40% from the time I go to sleep till I wake up.
Any insight would be wonderful. Thanks.
You're not the first person to report this, but my N6 battery life has been great for months on Nougat. Maybe it's one of your apps that isn't best suited to Nougat?

Thanks for the reply. I've checked the battery usage of apps and nothing seems bad. The next step was to check GSAM but I can't view usage per app unless I root my phone which I'm probably going to do today just to figure out what's wrong while I'm waiting at the dealer for them to fix my car.....
Overnight didn't notice an issue but it wasn't great only about 3 hours screen on time until I shut off location history. With location history off I'm now getting at least 5 hours screen on time
Sent from my Nexus 6
I was on the same problem, but i downloaded the image tgr and made a clean flash and now works perfectly!

Battery Drain on 9.0 Pie

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

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
which rom are u using now? stock or custom?

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

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.
