Battery drain after Oreo update?

So, after updating to Oreo, I noticed that my battery doesn't last long as when it was still in Nougat. I know full wipe is often the best recourse but I don't want to have to go through deleting all my apps and data and reinstalling them afterwards. That takes a loooooot of time. Anyone else who might be having the same issue? Also, any tips other than full wipe/factory reset would be much appreciated. Thanks!

i met the same issue also
before oreo, my phone battery was last long
when im gaming it almost take 6hour+ to drain off the battery
after updated it drain 40% within 2+ hours
so can i downgrade from oreo ?
somebody know what is the solution ?

Your device is probably learning how you use it (again) and I'd recalibrate the battery (let the battery die and charge to 100% with the device off)
I think you'll be back to normal after a few days

No issue here. My battery is just as good on Oreo, if not better.

Same here. Battery drains obviously faster. There's an app that obviously doesn't know how to behave with oreo.

No issues here, but I did a full wipe and start again fresh.. So far down to 42% at just on 4hrs SOT.. should easily get my usual 5.5hrs or there abouts

Guys always do a factory reset after a major update.

my battery was not good at android 7
but i flashed android 8 with newflasher
and turned on limited background activity and background data usage at app info for all of the system apps and other apps that support this feature.
my battery in android 8 has been perfect
and free ram is about 1.9 gb always

i suggest you to do that

Of course you're 100% right but sometimes it's just too much work. In any case my update settled down very nicely after 2 days.:good:

I disagree 100% with the need to do a factory reset after an upgrade! What, are we on version 2 of Android??? By this time, and with what we pay for these devices (and don't think that the software is free because it's NOT) and with the fact that they have become essential tools for most people, we should NOT have to do a factory reset every time a new(er) version is released and thereby forced upon us! It is up to the OEM to test these things thoroughly to make sure they work as advertised and expected. I do not have an entire day to devote to getting things set up correctly every time this occurs. If the OEM's do not want to test things properly then they should give us the option of installing at our own risk, and not mandating the upgrade.

I agree with you guess my battery is way better now, keeping in mind I have lifelog app and live wallpaper running in the background the whole day, I love 30% since the last time I charged, 6 hours since I unplugged the device and I have 1,30 hours screen on. Oreo is perfect ?

How did you set the limitations of the apps' background activities?

Lobotomizing your phone like that beats the purpose of having latest n greatest functionalities from an OEM / Android. Although I wish there was a wakelock adjustment as a default setting w/o root. It all comes to personal preferences. I only limit background activities to apps I almost never use and I let the rest do their thing cause I like some of the google services and also some tasker profiles require a frequently updated context .
As for RAM, it is meant to be used and now android is smart enough to adjust the resource consumption on it's own without the need of a app killer which does a lot more harm.
Needless to say Google Assistant keeps on pushing it's Ok Google Anytime function down our throats. It's now easier to accidentally activate it and they did nothing to optimize the power use of that thing. I tried it thinking maybe it's usable now. But it actually managed to overheat the phone leading to ~10% battery drain/hour (just because i had tv shows playing and it was comparing the dialog to the hotword). Not 'Ok Google'.
Sooo make sure you have that disabled. Otherwise you're in for a nasty surprise in loud environments.

It's better, I would say.

Try this app. Very comprehensive usage stats.

And don't forget to grant usage permissions via ADB for extended details.
We should post battery drain/hour and SoT.

Hi
I have the same problem. I've repare instalation by PC companion and it's still not working ok.

My battery was at 96% at 4pm yesterday, this morning at 5.30am it was 15%. This is crazy drainage, I used it sparingly yesterday afternoon, it was at 60% by 9.30pm (bedtime). I didnt touch from 9.30pm to 5.30am. 45% drainage with absolutely nothing running. Thats nuts. Has the battery gotten anyway back to normal for anybody? Or is there a fix without factory resetting the phone?

Battery life considerably worse after update to 9.0

OTA update to 9.0 available a couple of days ago so I let it install. Since then, I've seen considerably quicker draining of the battery, with my usage of the phone being much the same as before. For example, when I went to sleep last night the battery was at 64%, and there were no apps running according to a swipe up from Home, but when I woke this morning, battery was down to 2%. I normally charge once a day, and previously the battery was hardly ever below 50% after 24 hours - I'm a pretty light user.
As an aside, with 9.0 there no longer appears to be possible under battery usage information in Settings to see the percentage of battery that has been used by the various apps and processes.

Ok here. 62% drop over night doing nothing suggests you have a rogue app in there. I'm assuming you have ok cellular coverage and nothing has changed there by coincidence. I would reboot and force close every app you have that's not essential overnight and try again. Swipe up from home and clearing those apps doesn't force close the apps. Greenify is an app that (in manual mode) will make it easy to select as many apps as you want and force close the lot of them. If that improves the situation you can then begin to work out which app(s) might be doing bad stuff whilst you sleep...

Battery on my P2 has significantly improved with Pie even if I didn't have any major problem with 8.1 either. Overnight drain 3-4%. After regular use after a full day I easily exceed 5h SOT. Everything stock with just Greenify in non root mode. I couldn't be happier, best Android release so far for me.

I've had my p2 installed with PIE for about 2 days now. I suggest giving it a week (which is what I'm doing) and then getting a full overview of how my battery is performing. Usually, after any major OS updates, being that apps are trying to utilize your resources and a new version of Android would try to allocate and learn your usage (in this case battery), you'd get a much better definitive idea of your overall performance.
I also think that since its now available, turn on Adaptive Battery mode. After a day of upgrading the OS, Adaptive battery at my 26 hr mark of upgrade said that one of my apps was taking in a lot of resources to be used in the background (ES File Explorer). I made AB to stop ES from taking battery resources.
So in conclusion, if it a week and then you'll be able to get a better overall understanding of whether your battery REALLY has gotten worse or better.
Hope this helps!

Interestingly, my battery was dropping really quickly too after the update to DP3, I switched off Adaptive Battery and it fixed the issue completely.
I tried it again with Android Pie and the issue resumed, so I turned it back off. Maybe try this too?

Exact same problem here after updating. Even tried a factory reset in case it was an updating issue. Same problem. My battery is currently at 43% 4 hours after a full charge. And I've barely used it. This is really poor.
No new apps installed.
My Oreo battery life was great. I'll try shutting off adaptive battery as suggested - but seems a real shame if one of the flagship battery saving features is doing the total opposite on Google's current flagship phone!
Doesn't seem to be a massively common issue so not sure if a likelihood of a patch either

Just a quick update - Google play services has now become the biggest drain on my battery, just as it was before I factory reset after the first install...
Anyone else had the same?

I had the same issue and did the same thing... until dp3 and my battery usage was terrible again even with adaptive battery turned off. I ended up turning it on again and after about a week my battery usage was back where it was before. So there doesn't seem to be a magic bullet here. FWIW app usage offered no insight as to what was causing the drain in the first place.

THIS.
I got like 8+ hours of SOT.... no mobile network though, all day wifi use only.

I have this issue. Dropped about 40% over night. I found that turning wifi off stopped the drain completely. I did not have this problem with Oreo at all so it's not the networks im connecting to. Weird thing is this did not happen when I first installed Pie. This started happening about 3 days into installing. Also, I put it in safe mode and saw the same drain with wifi on vs off.

Hi guys,
I seem to have fixed my terrible battery life!
The below might be worth a try if you're still suffering from it.
I noticed in GSAM that RCSphone was the front runner in battery drain so did a little research and found this site.
SOLUTION: Turn off app preview messages (settings / google / app preview messages). Apparently its only function is to allow Allo messages to be received without the app. To me, totally pointless as i don't know - nor have ever met - a single person who uses it.
I've gone from draining 8-10% an hour (screen off) to around 2.5%/hour and from 1hr 35 total SOT to 3hrs 39 minutes with 32% left (and an hour of that was Google maps navigating, so a proper work out for the phone).
Do give it a try and let me know if it works for you.
Although there's room for improvement (idle 2.5%/h seems high to me!) and it's ludicrous that I should have spent several hours finding a fix for this on 100% stock android, I'm very happy to have a usable battery life back again...
Adam.
UPDATE: Seems like in the night I lost 40% again. Idle drain climbed it's way up to 5.6% in the night. Still an improvement from where it was before, but not quite as good as it first appeared...

@Burkules I drop 0.4 - 0.7%/hr over night with Bluetooth off/Wifi on/strong cellular signal. Much the same as it was with Oreo. Not quite sure why's there's such a big range (almost 2x) but either way it's ok for me. Did you try the technique above?

Cheers for getting back on this.
I left it on safe mode the other night and it still drained absurdly fast, which suggests to me it's a google system drain rather than rogue app, but will try again with app preview now switched off. Likewise will try greenify again and report back.

Likewise maybe app preview set to off will help me even more. If I recall correctly rogue apps can cause some google system apps to wake up, but perhaps not in safe mode...

So, switched off adaptive battery again (i'd enabled it after my short-lived miracle recovery the other day) and now I'm down to 4%/hour. Which is better but still really high for idling! Cleared cache and data in Google play services for good measure too as it still comes up super high on the list of battery drainers.
Booting into safe mode now to check the drain without adaptive there and will report back...
UPDATE: Exactly the same drain in safe mode. This is a straight up google problem....

Haven't tried this - but if the battery drain is the same in safe mode (with only google/system apps running) I can't see how it will make a difference. Ill be in rehearsal for several hours today so will force close everything and will then be leaving my phone idling for a few hours anyway.
I signup up to the google play services beta yesterday, and google play services no longer appears as one of the top battery users... but the battery drain is the same and the numbers given in *all* battery apps (Gsam/accubattery/system) don't add up to anything close to the actual % drain. System battery displays 15% of usage (with 'full device usage' on show) when the battery is quite evidently at 48% from full charge. Total cluster****. So pissed off I updated.
Have you seen any improvement in yours with any of these workarounds?

Nothing to lose by trying. And as I said, Greenify makes it easy/quick to do. Force closing is almost as good as uninstalling those apps as the vast majority of installed apps won't restart or run in background until you use them for the first time again. In my experience, quiescent battery consumption (e.g. noticed over night):
Is vastly affected negatively by poor cellular signal strength. Marginal coverage can really drain the battery fast.
Gradually gets worse between reboots
Can be improved (once it degrades) if you force close all the apps you've installed, and swipe away the background apps just before you go to bed!
If quiescent consumption suddenly rises I can normally fix it by force closing all the apps (not being sure which was the one gone rogue/suddenly misbehaving)
At night I generally have excellent cellular coverage, good WiFi, and Bluetooth is off. NFC is always off
I don't enable sync on 2 of the 3 Gmail accounts I have configured
I disable notifications from any apps I don't actually need them from
Quiescent battery consumption is between, say, 0.4% and, 0.7%/hr at home, around 2 to 3%/hr when out and about which I put down to all background data being driven over 4G instead of Wifi, and variable cellular coverage
I've not noticed quiescent battery consumption change between Oreo and Pie, but this may be because I keep force closing apps at night and not giving adaptive battery (which I have on) a chance to have the same effect intelligently
Turning off app preview messages has made no practical different for me
I'm completely stock (stock launcher, not rooted, etc.)
If you can't fix it, at least a factory reset as the next experiment has the option to restore *most* of what was there before (so long as you have had the backup setting enabled). But because not everything is restored it's still a pain. And if that doesn't work it's another factory reset and test and then restore everything manually and gradually :-S. But I think you already tried that?

Thanks, just tried that as well and my battery has stayed resolutely at 68% on idle beside me for the last few hours, previously it had gone from 100% down to 69% in about 4 hours whilst similarly doing nothing.

Deep sleep apps ( manually disabled)still waking up .

Normally when I put apps manually in deep sleep they don't do anything , run , wake up or use background data, send notifications , more so when their mobile data is restricted as well as their background activity. The highlighted even show as "manually disabled " within the apps menu. Yet they are showing up usage in background process within GSAM monitor.
Any ideas lads?
Edit. I checked their status under Dev menu, they were set to working _set , changed them to Frequent and will monitor.

It's a bloody joke , that deep sleep or sleeping apps setting under device care.
Just checked a few of my apps that are set to deep sleep aka manually disabled. Yet within Dev menu, their status is Active under standby apps.
Here's one example.

I checked mine and the apps are not "disabled" when I add them to deep sleep. I can still open the app, which would be impossible if the app was disabled.
I wouldn't trust the dev option as an indication that the app isn't sleeping (aka running in the background)... I have apps listed in mine that I haven't used yet, and there has been zero activity in the apps at all (battery use or otherwise).
Double check the battery use of the app and see if it is running in the background.
**Never mind, just woke up here and saw your first post edit. Hopefully the issue gets resolved for ya

Yeah you're right. The dev option status for those apps running or not appears to be variable ,.changing them changes them back to whatever they want to be i believe.
I was just shocked ( not really ) I had those highlighted two or three apps in deep sleep status via the battery care menu, yet when my device was left sleeping and untouched for 2 hours I opened GSAM and it showed those very same apps as being used in the background as the top five usage lol

I use Nap Time by Francisco Franco to put the phone in a deep doze. Been using it on all my phones for several years now. Just need a couple adb commands for it to work on an unrooted phone.

I'm good with 0.5 to 0.4% usage per hour in standby, however I might look into that in the near future if it may improve them. Current issue on hand if at all any might be SOT. I'm currently averaging similar figures to my last Samsung device which was an S10+
I guage all my devices battery performance by how much screen on time I can attain for around 40% of battery consumption. Currently averaging 4.5 hours. Was hoping for 6 plus but they might be over optimistic considering the 4370mAh battery.

With Nap Time I only lose 3-4% in a 12 hour overnight. I also have a lot oy Samsung bloat disabled too.

Question Did anyone notice the huge standby battery drain? Any way to measure what causes it?

First off, I love the phone and I'll keep it, but ever since I got the phone I've been wondering why it's draining so much in standby. It's my first Samsung phone since 2011, so naturally I assume it's Samsung apps/services that drain? Especially since I don't use any new apps than on my other phones and in the battery stats it doesn't really show any user apps that use a lot.
Anyone has way to measure what system/user apps drain during standby? Or even better, any dev that could do a deeper dive into this?
For example, I just lost 32% battery while sleeping for about 8h, it has never been this much on any other of my previous phones (OnePlus Nord/Pixel 3a/Pixel 3/Pixel 2).
In fact, my OnePlus Nord with 815mAh more than the Flip3 is currently on last charge 3 days ago (it doesn't show me hours anymore) and 2h35m SOT and 25% battery left. On the Flip I just now got 17h with 1h30m SOT and 5% left. Settings all similar besides location accuracy turned off for the Flip as that was a massive drain.
Something must be unintentionally draining the battery during standby and I really hope one of you smart guys can find it. Or Samsung fixes it with an update..

I disabled AOD and any unnecessary account sync processes. It's only drained about 2% in standby the last 5 hours, but there are still some things to finish configuring.

How old is your device? You got to give it some time to settle. I had 15% battery drain the first night, after that it went down to 5%.

The first step in improving the battery is to remember that this isn't any other phone. You may want to explore what options are available and what all you have enabled. By default, almost everything is on to show off all the cool new features that make this a Flip 3, not a OnePlus Nord.

Which Flip features are in use during standby though? During standby it's just another phone

Not true. Samsung has a bunch of features still in use.
Settings -> Advanced features -> Motions and gestures has a whole collection of things that are still running when the screen is off (and most aren't useful to the Flip, but came from "another phone").
Settings -> Cover screen allows you to disable turning on the screen when notifications arrive, if that is not something you need.
Also, unless you are using the app to lower the refresh rate, you may be running a bit high when idle.

I've turned a few things off there, but a lot of them OnePlus has too + a few more, which I had all enabled

I didn't really get any notification during last night, so I doubt this was the culprit

Yes I'm using that app and have it set to 48-96Hz
Appreciate the help, I believe there must be something that's unintentionally draining and while I went through every single setting in the beginning, I'm still very new to OneUI (and also impressed how far it came from the TouchWiz ****show)

One thing I always forget is that a lot of those features are running services and polling when they're enabled. Even though I'm not touching the screen with the tap to wake enabled, it's constantly waiting for that tap when it's asleep. Any one isn't a big impact, but Samsung has so many "convenience" features that I end up wasting battery to never use.
The calibration period is also horrible. Android 11 is slow to calibrate the battery and Samsung is worse. You can get a good idea of what is draining battery by going to Settings -> Battery and device care -> Battery. That may help find out if it's a renegade app.
One thing Asus does that I wish Samsung would embrace is Auto-start management. Some apps aren't efficient at polling for notifications and more than once have been the cause of major drain.
Another one even Samsung admits to be a source of drain is the edge panels. If you don't use them, it's best to kill the entire feature.

I just assumed it's not a big impact as OnePlus has those as well, for example draw a "V" on screen for flashlight or ">" to skip song besides the regular double tap to wake and it never appeared to be a battery issue for me before.

Do I assume correctly that some system apps or similar are hidden there? I just did the calculations and the percentages only make up 43.6%. I attached a screenshot

OnePlus also optimizes them better than brand new Samsung firmware. I had a lot of stuff enabled on the Note 20 Ultra that I won't be using for a month or two now.
Some apps are excluded, but it will let you know if it's something not included with the phone.
Another good idea is to uninstall, disable, or "adb uninstall" any bloat you don't use. Besides clearing up space in the app drawer, it kills off services you don't use. A lot of the apps will run services even before you sign in, even though they aren't actually handling any data.

I already went through the list and uninstalled which I 100% knew what it was and that it's not needed, but not sure about 99% of Samsung stuff. Some Samsung apps on the phone I don't even know what they are and when I start them it just prompts to agree to some terms before starting the app... I'll have a look around for a Samsung debloat list

If you have the unlocked version, they allowed uninstall for a lot of apps that were previously locked. A lot can also be downloaded later from Google Play or the Galaxy Store if you change your mind.
I use Firefox, so I uninstall Samsung Internet and Chrome. Members and Health are two big ones that like to run those "please enable us" services. It's a lot of deciding what you might use versus what you can live without.
Another good idea is to add anything you won't use, but didn't remove to deep sleeping apps to kill it's ability to run in the background. It's the closest thing to auto start management without rooting.

So far I don't have much hope sadly. Whole day currently at home and not using the phone much and it's looking like in the screenshot (screen off, loosing almost 2.7% per hour, as comparison my OnePlus is at 0.9% per hour)
https://imgur.com/RLITZwQ
It's 21:21 at the moment and I'm at 54% after 9h 42m (comparison OnePlus with 815mAh more: 7% after 79h with 2h54m SOT)

I'll probably head to bed in a few hours and then report back tomorrow morning how much I lost during the night..

I'm not claiming to have amazing battery life, since I almost considered keeping my trade-in and returning this one over it. I am interested why it is so bad for others, though.

HOLY **** I would love to have this battery life. I'm literally not doing anything with the phone and just loosing so much. I'm pretty much the opposite of a power user, so my phone is in standby most of the time and loosing so much is pretty frustrating.
EDIT: I might have an idea why it's so bad for me, I don't really have reception in my apartment (as you can see on my screenshots), so I assume it's constantly trying to get better receptions, I see 2 bars sometimes, but most of the time 0. I'll keep my phone at the window where I have reception for the rest of the day and see if it makes a difference. (Although the OnePlus has also bad reception, but does have a different carriers SIM card)

Dependencies, dependencies, dependencies... some of those apks just sit there unless needed.
Do not disable apks/services unless you know what they do and what, if any, their dependencies are. Go too far and you'll end up in a boot loop.
What works for others probably isn't ideal for you.
Package Disabler is a better option as you easily toggle apks on/off as needed.
Screen off the serial offenders tend to be Google backup Transport, Framework and any cloud apps.
Try disabling Google play Services at night and see if that helps. You may need to disable Find my Device first as System Administrator if disable is greyed out.
Disabling play services also kills Gmaps and Playstore which are know hogs. Gmail as well to a lesser extent.
Google Firebase, do you need it? If not disable.
Carrier, Google, Samsung and app feedback, disable.
Using power management can cause erratic behavior and not solve the problem. Treat each power hog on a case by case basis instead. It takes a lot longer but yields a cleaner, more stable setup.
Play with it, go through -all- the settings. It's actually quit fun to explore and almost impossible to crash and burn.

Battery Drain Diagnosing

I have had a battery drain for several weeks now. It isn't to severe but the biggest issue bothering me the most is at night it is draining about 5-6% even with battery saver turned on. It used to be that in normal mode, the battery would only drop 2-3% over night. I do not charge at night.
I am fully updated and I even reset the phone to factory 2 days ago and the issue still persists. Nothing seems to stand out in the battery stats with regards to apps sucking battery %. So I think this is an issue where it is not going into Doze or Deep Doze but I dont know how to determine that.
Any suggestions how to find the problem?

(on android 10)
When you wake up in the morning...
Go into "Settings"
Then "Battery"
Then click the top right three dots
Then select "Battery Usage"
It should show you which apps used the most battery during the night.

I have done that. No apps appear to be doing anything unusual. There are no battery hogs showing up. Not even excessive google services usage or anything. That is why I think this may be a situation where it isn't going into doze or deep doze like it used to but I dont know how to check or monitor that. that info doesn't show in battery stats.

I never heard of this doze/deep doze mode - where did you see this?
I ask because I typically get 10% loss overnight with what I thought was very good because the pixel often then calculates I have 2 days of remaining battery life with that stat.

You can google it as there are tons of articles about it but here is some insight into it from the developer side: https://bignerdranch.com/blog/diving-into-doze-mode-for-developers/

OK, so it says in order to go into deep-doze, the phone:
1) Must not be charging
2) The screen is off
3) The phone is not moving
So, during the night, are all three of these conditions met?
Also, the device will come out of deep-doze if an incoming push notification is received - could one of your apps be receiving push notifications during the night?
Also, "Any process using a foreground service is exempt from Doze Mode effects, which is key for long-running applications"...do you possibly have any apps that have a foreground service?

Have you tried to switch off Bluetooth, it has a huge impact on battery even if not in use.

I've used apps before. Can't remember but gsam might be one...
It's possible to identify apps that are holding wake locks. That's the first place to check for battery drain.

all the apps I can find to track wake locks seem to need ROOT. I'd rather not do that as then I lose OTA updates.
After some extreme disabling of user app, system apps, services, etc. I finally got back to 3% battery drop overnight. I'm not sure which one was the culprit yet but i'll start enabling things as I need them and keep monitoring.

I'm having heavy battery drain. I already charged to 100 and less to 30 minutes i lost 10%.
It began since last update on my case.

After you see a big drain, DON'T plug in and...
Go into "Settings"
Then "Battery"
Then click the top right three dots
Then select "Battery Usage"
It should show you which apps are to blame for the drain.

Gsam needs permissions but these can be set with USB debugging, no root needed.

So one thing I have learned is that it appears every time I reboot, gsam thinks my wifi is on even though I have it off. If i turn it on and then back off. Gsam now says wifi is off.

So i got through the night at 3% battery drain but now I am realizing that my phone will not go into deep sleep during the day. Any suggestions how to fix that?

According to the details in the link posted earlier, it will never go into deep sleep if the phone is moving.

I leave my phone sitting on a desk all day. There has to be some Android services that only operate during the day but i can't dtermine what those might be.

Was gsam able to identify which app was holding a wake lock?
Or maybe triggering frequent wakeups?
Both of those would prevent doze...

Battery Guru is good for chasing drains (with ADBs), add BBS + adbs and you can find anything using them together!

Google play services mostly. There was a large amount from "Adaptive connectiviy" but when I disabled that those went away.
