Hi All,

Is anyone getting really bad standby drain on the Exynos version? Soon as I take the phone off 100% charge within minutes of checking it again it falls down to 98% with nothing running or in the background. Last night while I slept for 8 hours it lost 11% which 0 apps running in the background. Please let me know cheers.

Hi I've had the same experience with the note 10+ s20 ultra and now note 20 ultra, at work today on lte connection I got 2.5 hours sot over 12 hours at the end of which my battery was empty. This might improve when the software learns my usage patterns but I found there's nothing you can do about the standby drain, the only 2 brands in my experience with good standby battery life are Huawei and apple.
[Samsung Galaxy Note 20 Ultra Questions & Answers] xORJSx:
Yeah I had the exact same issue with my note 10 plus even with learning usage which I sent back. Just come from the Huawei Mate 20X which had the best battery life to this. Hopefully it may improve otherwise I can't see myself keeping it.
[Samsung Galaxy Note 20 Ultra Questions & Answers] kradcliffe:
I had the P30 Pro and the battery life was far better than this. Let's hope it improves over the next few days.

Just installed the new update which may help.
[Samsung Galaxy Note 20 Ultra Questions & Answers] shvyue:
4h normal use (about 1h screen on), the battery dropped from 90% to 50%
[Samsung Galaxy Note 20 Ultra Questions & Answers] angka8:
The standby drain is really bad. Really hope after few days of usage it can improve tremendously
[Samsung Galaxy Note 20 Ultra Questions & Answers] gavinfabl:
4% overnight only.

Yesterday, 6 hours SOT. 7am to 10pm. 120hz. Typically getting 5 to 6 hours SOT.
[Samsung Galaxy Note 20 Ultra Questions & Answers] doctor78SI:
Did any of you tried putting apps to sleep apps in settings? I did that on my note 10 plus and I think it matters.
[Samsung Galaxy Note 20 Ultra Questions & Answers] hongjiu923:
Exynos or Snapdragon ?

i am only getting 5hrs + SOT on 120hz adaptive with total of 10hrs standby time
[Samsung Galaxy Note 20 Ultra Questions & Answers] gavinfabl:
Exynos. Quite normal to get anywhere between 5 to 6.6 hours SOT. With 120hz and everything on.
[Samsung Galaxy Note 20 Ultra Questions & Answers] freezingpoint:
Do you guys disable any bloatware apps? Either via adb or package disabler. There are some apps that run like Samsung push service, smart things, etc.
[Samsung Galaxy Note 20 Ultra Questions & Answers] gavinfabl:
Not interested in doing anything like that, so no.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Vyshakh_88:
7 hours sleep time. Battery discharged only 3 percent.

Before sleep it was 81%. Morning woke up to 78%. Exynos version.

[Samsung Galaxy Note 20 Ultra Questions & Answers] umbrokhan:
Turn off auto brightness and turn off adaptive power saving.

I had battery drain since Galaxy S4, S6 Edge Plus, S9, S20 Ultra and Now Note 20 Ultra. Same story every year about battery drain.
[Samsung Galaxy Note 20 Ultra Questions & Answers] enjoylife1788:
How does Auto Brightness affect the standby battery drain? I am curious.
[Samsung Galaxy Note 20 Ultra Questions & Answers] umbrokhan:
When you go out doors day time or sunshine your screen automatically goes full brightness so it will drain battery quickly. Keep your screen brightness low or medium

Now I'm past the first week or so I'm having no battery issues. Happy as usual with my next Note!
[Samsung Galaxy Note 20 Ultra Questions & Answers] eVoHicks:
I get around 3% battery drain in around 7 hours overnight, but then at work I might not use it for an hour and its drained 3 or 4 %. Maybe alot to do with signal.
[Samsung Galaxy Note 20 Ultra Questions & Answers] umbrokhan:
If your using WiFi network battery drain is less.

If your using 5G or 4G LTE then battery drain is a lot more.
[Samsung Galaxy Note 20 Ultra Questions & Answers] kasey348:
i had the same problem, just turn off 5G and you will see the difference.

note 10 5G have the same issue, my s20 ultra have almost twice battery life than this note 20.
[Samsung Galaxy Note 20 Ultra Questions & Answers] ram4ufriends:
How do we turn off 5G?
[Samsung Galaxy Note 20 Ultra Questions & Answers] GDHAMTON7:
One way you can try is using Samsung band selection app. You can force the phone to lock on to 4g LTE... There may be an easier way than this but this works
[Samsung Galaxy Note 20 Ultra Questions & Answers] xORJSx:
I done this the day I got it as I only have a 4g sim and no improvements :(
[Samsung Galaxy Note 20 Ultra Questions & Answers] xORJSx:

I’m also getting the same wakelock as you do on my Note 20 Ultra and it’s draining my battery during standby. Did you manage to find a way to fix it? ?
[Samsung Galaxy Note 20 Ultra Questions & Answers] blackhawk:
Check running services in Developer options and also the cache to see if you can find it.

Autostarts will probably see it:

[Samsung Galaxy Note 20 Ultra Questions & Answers] Limeybastard:
Yep , I'll vouch for the mate 20x battery life. That thing was a beast which I also owned.

As for the OP question. I owned an exynos note 20 ultra and posted screen shots of gsam and accubattry in the real life sub forum of the note 20 ultra xda sub section.

Didn't have any issues with SOT or standby. Most the BS made up against exynos is just that.
[Samsung Galaxy Note 20 Ultra Questions & Answers] blackhawk:
The difference between the two variants is small even in the specs.

Either one can be a wanton battery hog if misconfigured which can be the case right out of the box. They can be a pain when like that but they can be sorted out.

Any PC I ever bought or built needed to be optimized.

Why should this handheld PC be any different?
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
Cameraservice_proxy wakelock

I've already checked in running services and cached in developer options but it's not there. I installed Autostarts to see if it will appear but it doesn't. But I still see it in wakelock detector and it's running under Android System. The thing is it seems to run only when the screen is off and not when I'm using the phone.
[Samsung Galaxy Note 20 Ultra Questions & Answers] BHart1990:
You are right.
[Samsung Galaxy Note 20 Ultra Questions & Answers] bmonteiro:
This wakelock appears to be the system polling the light codition for the adaptive display refresh rate. I find it weird to experience this wakelock when my screen is set to 60hz, and it also appears the be sucking a lot of energy, because on my phone this wakelock is always on top of CPU comsuption.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
Cameraservice_proxy wakelock

I also find it weird since my phone is set to 60hz only yet it still appears in my wakelock detector app under Android System. I even installed Naptime to force doze and prevent wakelocks but it doesn't seem to work.
[Samsung Galaxy Note 20 Ultra Questions & Answers] blackhawk:
Install Gallaxy Labs Battery Tracker.

Install Karma Firewall to spot the apks phoning home.

Use it's logs to see who's doing what*.

Turn off all cloud crap, all feedback, Goggle Backup Transport, gmail/contact/callender sync.

Firewall block habitual offenders and observe what they do/possible negative consequences and work arounds.

I briefly toggle on Goggle Play Services so gmail will manual sync. GPS is a complete hog that constantly runs. It's needed for Playstore too which should be PDed and firewall blocked.

You get the idea.... no easy solution; try/observe/adjust.

Do not enable any power management as they will most likely make things worse!!! Only set the screen resolution/performance parameters.

^remember this^

Install a package disabler; I have around 86 blocked.

Or use ADB to shut them down; many are never needed.

It took me months to completely work this out on my 10+ running on Pie. You can see in the attached image how clean it's now running... took a year to get it fully dailed in to this point. One reason I rarely update and then only one apk at a time.

Q will probably behave similarly but each set up is unique; no cookie cutter solution for any.

Plus what each user needs/wants and what they're willing to pay for it in terms of performance and battery life.

*Example; the browser Brave will constantly poll unless force stopped... it's a pig.

Closing it's window doesn't shut it down. No way to alter it's misbehavior except a manual force stop.
[Samsung Galaxy Note 20 Ultra Questions & Answers] bmonteiro:
Does anyone here uses Galaxy Watch 3 together with it's note 20 ultra and would like to share it's experience regarding battery usage? Mine when heart rate is continuously monitored, the Bluetooth (phone) service uses about 15% of battery during the discharging cycle. And I remember that on my old note 10 the usage was not that bad. As soon as I set the watch to manually measure and reboot the phone the Bluetooth usage goes down to 0/1% through the whole discharging cycle
[Samsung Galaxy Note 20 Ultra Questions & Answers] Limeybastard:
So this wake lock that you guys are mentioning, is it cutting in to your standby times and if so what are you comparing it with? I have the same wake lock and my standby times and deep sleep is typical of any other previous samsung device that I have owned in the past. Deep sleep around 94% and standby drain it approx 0.6 to 0.4 % and hour overnight.
[Samsung Galaxy Note 20 Ultra Questions & Answers] blackhawk:
Try a network reset... that might get it. Clear the system cache in boot menu.

Maybe another unneeded apk's constant running and/or polling causing it.

Goggle Play Services (clear it's data) is a prime candidate; I firewall block this except briefly to use gmail.

Google Backup Transport and Framework too; I package block both. Same for Sammy cloud crap.

Karma Firewall might help you spot the offender(s).

I've found this app's logs very useful for doing this.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
It sure does have an impact on my battery life. If it doesn’t run in the background, my battery can last up to about 3 hours of SOT usage from 100-80%. But when it runs in the background when the screen is off and I’m not using the phone, my battery only lasts me around 2 hours of SOT usage from 100-80%.

Note 20 ultra snapdragon

And my standby battery draining extremely bad

It loses too much battery while I'm sleeping
[Samsung Galaxy Note 20 Ultra Questions & Answers] Limeybastard:
What makes you think that this is the cause of your battery drain , because you see a high wakelock figure next to it ? Lol you also mention when it doesn't run you get better battery life, remind me when does it actually not run and more importantly how do you know when it's not running.?

Reading those figures on wakelocks from Android system doesn't necessarily mean that is the actual source of issue.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
Well previously on my Note 10+ I experienced a high drain during standby time. I put all my apps to sleep but I can't seem to fix the problem. When I installed the wakelock detector, it appears that a wakelock has been running constantly when the phone is in standby. As soon as I installed Naptime to force doze and disable wakelocks during standby, the wakelock doesn't appear anymore in wakelock detector and my battery standby time improves significantly. Therefore, learning from my past experience with my Note 10+, I'm pretty sure this cameraservice_proxy wakelock is the cause of my current battery drain during standby on my Note 20 Ultra.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Limeybastard:
Try turning off all your screen features like double tap to wake , raise to wake, tap for AOD etc then report back.
[Samsung Galaxy Note 20 Ultra Questions & Answers] blackhawk:
That's not it. I'm using all of those.

With AOD on usage should be 1%.

Power management doesn't help and will even make it worse.

The Sammy and Google system apks are prime offenders. There are many...

This is what a tamed 10+ looks like:
[Samsung Galaxy Note 20 Ultra Questions & Answers] Nastrahl:
If i understand you well, do i also need to activate high performance mode instead of optimised in the energy power saving settings ?
[Samsung Galaxy Note 20 Ultra Questions & Answers] Limeybastard:
Not sure who you were quoting for what response to be honest .

With AOD I mentioned turning tap to show plus other "features" that use sensors on device for wakeup. Whatever it is , it ain't an issue, it's samsung hardware working un-efficiently with Googles typical power ( spy) hungry OS. Then you add all of the One UI features into the mix on top of Googles , equals we need bigger batteries for every new incarnation of Android on new hardwarethe more mAh you get the more they tax it.

[Samsung Galaxy Note 20 Ultra Questions & Answers] blackhawk:
I'm on a completely different model and OS but even both were they same, each user's needs and profile are different.

There's no cookie cutter solution to replace digging into it yourself and fixing the issues. I have about 80 apks package blocked and many firewall blocked.

For me the Optimize power setting works best with none of the battery saving options toggle on. Only fast charging is active.

Many times the factory loaded apks run best.

I've also disable all feedback and all cloud crap except gmail which has auto sync disabled.

It's an ongoing process. I play with it, change and observe as well learning what different apks do and their dependencies when possible.

It's very much a fluid thing as I muck with it a lot especially when I see any excessive usage crop up.

Occasionally I find malware, twice in the last year but nipped it in the bud; minimum or no damage, no reload needed. So it's not just all about battery life that I constantly play and scruntinize it.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
After disabling all screen features that you mentioned and other related screen features, it seems to have no effect in reducing or preventing the wakelock. Today, my SOT from 100-80% barely reached 2 hrs because the wakelock was running in the background for about 10 minutes. Without any or almost no background wakelock, I've no problem getting more than 2 hrs of SOT from 100-80% just like back on my Note 10+.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Limeybastard:
I tried it also, didn't make any difference. But that so called wakelock also runs on mine. I'll post a GSAM screen shot to show you how long it runs for over night. Since I've only just now charged my phone 2 hours ago and it has ran for 1.1 minutes.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
Alright I'll wait for your updates. Interesting to note that yours only ran for around 1 minute after 2 hours since charged while mine already ran for 10 minutes in 2 hours of usage. I wonder what could have caused the difference.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Limeybastard:
Ok, here's mine after over 12 hours since being disconnected from charger. LTE usage only.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
It seems that yours doesn't run in the background that much and thus not affecting your battery life. Mine is horrendous. After about 1 hr 30 minutes unplugged from the charger, it already ran for more than 5 minutes.
[Samsung Galaxy Note 20 Ultra Questions & Answers] blackhawk:
A late night experiment... you know for scientific purposes.

Does it goes nuts in safe mode too?
[Samsung Galaxy Note 20 Ultra Questions & Answers] Limeybastard:
How's he going to check GSAM when after let's say 6 hours or so of safe mode is performed ?
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
It's not even during the night..the screenshots are from this morning when I'm actively using my phone. It looks like every time the screen is off if will run in the background. I've tried putting my phone in safe mode yesterday and it seems to run in the background too since the battery goes down in a similar manner. But I can't confirm it since all my wakelock detector apps are disabled in safe mode.
[Samsung Galaxy Note 20 Ultra Questions & Answers] blackhawk:
Looks like a little bugger.

Karma Firewall* won't log with Q so that's out; wonder if an apk is mucking it up there. Goggle Play Services wuvs to do that.

I found this:

https://android.googlesource.com/pl...android/server/camera/CameraServiceProxy.java

If you have a package blocker you can go after Google Backup Transport, Google Services Framework and Google Play Services (GPS). Try clearing their data.

The two former can be package blocked while GPS is needed for gmail and Playstore, but you can toggle it on/off with no harm other than a reboot to use Playstore. Firewall blocking is effective with GPS too and cuts it's battery usage at least on my 10+; this is the easiest solution for getting this pest under control.

*you can still firewall lock down wayward system apps which will reduce battery consumption.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
Will disabling all those packages work? Since it doesn't seem related to camera services which is what the name of the wakelock implies.
[Samsung Galaxy Note 20 Ultra Questions & Answers] blackhawk:
That link may give you some clues to dependencies involved. Those Google services I mentioned are known hogs on my 10+ Pie device.

Just a guess on my part that they may be the cause.

Disabling Google Backup Transport in Google settings didn't stop it from using resources.

What I did was package blocked GBS and GFS* as well as clear their data when they act up (even PBed they remain partially active). I firewall blocked GPS except briefly to use gmail; toggling GPS on while gmail is running then off after a second or two will allow gmail to work for a few hours.

I know it sounds extreme but it completely tamed my 10+ GPS polls the internet 4 times every minute, firewall blocking it along with the previous mentioned modes reduce battery consumption noticably including during the night.

I'm still playing with it but it's the best solution I've found as this phone is not rooted.

Unfortunately true to form Google took away even more diagnostic tools with Q. Even with Pie it's a pain. Google says it's for security but it sounds like a load of $hit to me. Google is the biggest security risk as best I can tell.

Be nice to have some of the real time diagnostic tools that I have in Windows like Process Viewer. Android is getting as bad as Apple.

So I'm reduced to just watching the shadows on the cave wall so to speak:(

*Google Framework Services must be package blocked together with Google Backup Transport.

All Samsung cloud apks too. All backup on my device is now 100% self contained via SD card and a PC copy of same. Backup copies of all my apks are stored as well so Playstore isn't needed for a full reload. Faster and easier.

I took the cloud junk out of the equation completely.

If you're using cloud services... pick your poison.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
After some observation, I've found out that this particular wakelock will always run in the background when I put my phone inside my pocket/bag or putting it on any surface facing downwards. When the phone is put on a surface facing upwards and the screen is off, it doesn't run or only for a bit if it does. But whenever it's inside my pocket or bag or facing downwards on a surface and the screen is off, it will definitely run and thus drains my battery.

I've tried to disable packages related to camera service but it seems not to help. I'm assuming that there could be a bug that causes the wakelock to run whenever the front camera is obstructed especially when it's inside my pocket or my bag. But right now I can't figure out what should I do to prevent it other than not putting my phone inside my pocket or bag which is very cumbersome.
[Samsung Galaxy Note 20 Ultra Questions & Answers] blackspp:
Standby drain I'm not so worried about, how fast the first say 10 % disappears from a full charge puzzles me.

Charged full, remove from charger, switch on, sign in, put it away for 4 minute.s Look and battery is already down to 96%. without having done anything. And than it drops quickly further to around 85 - 87% and the rest of the day it's pretty good.
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
Do you have any wakelocks running in the background that could have caused the battery drain like in my situation?
[Samsung Galaxy Note 20 Ultra Questions & Answers] blackspp:
Hi, no, I haven't noticed any. ADBed all bloatware too, it's quite a minimalistic setup now. I even removed lawnchair, using stock launcher...
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
Interesting. Can I know what bloatwares that you've removed using ADB?
[Samsung Galaxy Note 20 Ultra Questions & Answers] blackhawk:
I don't think it has anything to with the cam; it's the proximity sensor. Try altering it's settings.

The wake up on pick up junk and whatever else other than phone calls.

Clear system cache.

I've seen people say the proximity sensor on this model is part of the cam (which I doubt) or some that show it near it's usual spot.

Which is it (use finger)?

Isn't this fun?:laugh:
[Samsung Galaxy Note 20 Ultra Questions & Answers] Azzreiz:
Based on what you said, the proximity sensor looks like it's not a part of the front camera. It seems to be located slightly to the right of the front camera. However this particular wakelock's name seems related to camera even though it looks like it's related to the proximity sensor. I tried to find any packages that could be related to the proximity sensor so that I can try to disable them but I couldn't find any.

This wakelock is really frustrating me since it never appears on the Note 10+, my previous phone, which uses the same sensor setup as the Note 20 Ultra.
