[Samsung Galaxy S23 Ultra] vpsj:
Does anyone know what "Prevent sleep by AssistantDelay" means?

I checked with battery historian, and that is the biggest issue I have. My phone basically never dozes because this wakelock keeps the CPU running the entire night every 20-30 seconds.

My SOT has gone down from 7.5-8 hrs to around 5 and the phone also dies under 20 hrs whereas it used to last well over 30 hrs for me (with the same usage).

It's not the 'Screen on' battery rate of change that I'm worried about.. that's mostly fine.. it's when the phone is in standby. Whether I turn off auto sync, keep it under power saving mode, or do anything at all really.. seems to be making no difference.

Any idea? Previously I had a OnePlus 5T and for damn near 6 years that phone never lost more than 3-4% overnight even when I slept for 7-8 hrs.

S23U loses 1.5-2% each hour when it shouldn't even be doing anything at night.

I have obviously tried the basics (restart, clear cache from recovery etc) but nothing has worked. Need some advice.
[Samsung Galaxy S23 Ultra] amirage:
It's the edge panel notifications that light up when you get notifications.
[Samsung Galaxy S23 Ultra] vpsj:
I don't even have edge panel notifications turned on though.

It's so bizarre that this keeps the phone from dozing. Is there a fix? Can I completely turn off/ disable edge panel lights feature somehow?
[Samsung Galaxy S23 Ultra] Big Bread:
Disable the service using ADB commands or UAD.

I had the same issue a while ago, but with AOD. I never use AOD, but my phone would turn on a grey screen throughout the night and drain my battery, even though AOD was turned off. Even when some features are turned off, their services still run in background.
[Samsung Galaxy S23 Ultra] amirage:
You can change the notification settings from brief to detailed and see how it impacts. I have kept it on though..the impact isn't so bad to remove that feature.
[Samsung Galaxy S23 Ultra] vpsj:
The notifications are already set to detailed (which is why I assumed the Edge lighting thing is disabled since that option isn't available in detailed mode).

I don't know if it's because of the 6.1 update or something else but my standby battery is definitely draining faster than usual. I am used to less than 1%/hour but it's closer to 2%/hr now. Even after clearing the cache.

Maybe edge lighting is not the culprit here but _something_ is, since the phone seems to never go into Deep Doze

YouTube kills battery life on my S23 Ultra.

Very high CPU/GPU usage wtf? Phone is very hot by watching a 720p YouTube video.

Google can't make something right, can they? 😡
[Samsung Galaxy S23 Ultra] Big Bread:
Two days after April update. Same usage as last post (with buds 2 pro and watch 5 pro). Battery life (and SOT) could easily surpass Dec and Feb patch if I use more than 67%.

I'll be staying on April until OUI7.0 launches. Cba to gamble battery life with samsung every month.
[Samsung Galaxy S23 Ultra] TeeJae360:
Wow! This is Nuts.
[Samsung Galaxy S23 Ultra] iamnotkurtcobain:
How do you get such a good battery life? Any special settings? Is this with Standard or Light performance mode?
[Samsung Galaxy S23 Ultra] Normusmaxamus:
I just debloat the apps I don't need. Turn location off and have darkmode on all my apps I use. Also I have a black wallpaper for my home and lockscreen. I use standard performance mode.
[Samsung Galaxy S23 Ultra] iamnotkurtcobain:
Same for me. Maybe you debloated some more apps than me. Do you have a list what you have debloated?
[Samsung Galaxy S23 Ultra] Normusmaxamus:
I did post it last week. But no problem here it is. Hope it helps.

Thanks mate!

Has anyone odin formatted the device after the last update? Just wondering if it will lead to any battery savings? I have always wiped cache post every security update...religiously
[Samsung Galaxy S23 Ultra] bodomfan:
Wow
[Samsung Galaxy S23 Ultra] vpsj:
Hi, can you please tell me where is this source code and how can I check mine as well?

I used my phone's bugreport and tested it in my privately hosted battery historian and I see the same wakelock keeping my phone awake every 20-30s. I earlier thought it was because of your Galaxy Mhz app but I can now confirm that's not the case.

Is it possible for any other service to also use the same "Prevent sleep by AssistantDelay" wakelock? Is there a way for us to search the Android system by this key phrase and find out? Because edge lighting doesn't seem to be something that should cause so many wakelocks.

Also I have kept it completely disabled and yet this wakelock continues to occur for no reason at all. I just want to find out why.

Please reply if you see this. Thanks!
[Samsung Galaxy S23 Ultra] tribalfs:
It's decompiled from oneui rom framework files. This one is particulary from services.jar.

Yes, this can also be caused by apps/services that intercept notifications
[Samsung Galaxy S23 Ultra] amirage:
So long story short...we will need to live with it right
[Samsung Galaxy S23 Ultra] linom:
This is phenomenal. Are you on Wifi only or use 5G? And do you disable mobile data while on Wifi? The debloat file also has routines which are disabled, which is a bit of a surprise as I use it to switch to 2G when on Wifi. The best I get is a day and a half with avg of 6-7 hr SOT and if I watch videos about 9 hrs SOT.
[Samsung Galaxy S23 Ultra] Normusmaxamus:
I use both WiFi at home and 5G when I'm out and about. I don't disable mobile data only what is in my debloat file. I don't use routines has personally. I have no need for it. That's not bad sot or battery life your getting on your device.
[Samsung Galaxy S23 Ultra] linom:
Thanks. Is debloating the secret sauce to 3 days of standby time? Used to debloat and root a lot until S10 series but then stopped doing it given Android's battery improvements and risk of breaking something.
[Samsung Galaxy S23 Ultra] Normusmaxamus:
Everyone is different I guess. I just disable all the apps and bloatware I don't use. I'm not rooted either just plain stock. It's suits me for my needs.
[Samsung Galaxy S23 Ultra] Big Bread:
How's the second April patch going? (It was released yesterday, I think.)

This is April's second patch
[Samsung Galaxy S23 Ultra] Emperon:
I'm considering to downgrade to 5.1. Which 5.1 firmware version is/was the best for battery life in your opinions?
[Samsung Galaxy S23 Ultra] _GRIZZLY_:
Last version of course, with bootloader "3"
[Samsung Galaxy S23 Ultra] darek5cro:
You can downgrade to Android 10 if you want.. It wont change because this phone is 1.5 year old. I dont know what do you expect but you cant get 12h SOT with S23Ultra after 1 year of use. Deal with it and be happy that its better than S20 and Note 20 series

I have latest firmware and its always same, 5h SOT - 50-55% battery.. and so it is since day one I bought it (bloatware removed and thats all)

[Samsung Galaxy S23 Ultra] trevzv:
Something is wrong, I use light mode, aviation mode, just wifi and Bluetooth sometimes, 120hz, some apps disabled, but the battery still terrible.
[Samsung Galaxy S23 Ultra] Klaudas:
What exactly is wrong? The battery life seems pretty average to me. The only thing I can see that might be causing the issue is that you are charging your phone to 85%. Also, you have Battery Guru installed, which could be wasting battery life as well.
[Samsung Galaxy S23 Ultra] Fl1nt91:
Charging battery to 85% is like charging to 65%. It lasts a lot less that just a regular 85% of the total
[Samsung Galaxy S23 Ultra] matty100147:
Pretty normal to me, I have flight mode on with WiFi all day and I can only get 6hrs or so charging my phone to 100%
[Samsung Galaxy S23 Ultra] trevzv:
Guys, I did about 7:30 hours of screen charging the phone up to 85%, it got very bad autonomy after the last updates.
[Samsung Galaxy S23 Ultra] Klaudas:
I think you updated a bunch of applications as well in the meantime not just OS🙂
[Samsung Galaxy S23 Ultra] iamnotkurtcobain:
OneUI 6.0 left, 6.1 right :(
[Samsung Galaxy S23 Ultra] amirage:
This is called planned obsolescence. Android since 10.0 was designed to run on lower specd devices yet we have flagships struggling to achieve better battery life after the launched Android version. The only thing that comes to mind is Samsung's version of planned obsolescence making sure devices struggle with battery life even if the battery is replaced. This is where AOSP comes to play however getting it to run on Samsungs is a nightmare. This is probably how tech is going to be henceforth.
[Samsung Galaxy S23 Ultra] darek5cro:
Folks.. accept that battery wont (and cant) last same after 6 months, one year, two years of everyday phone usage.. deal with that .. or buy new phone.
[Samsung Galaxy S23 Ultra] amirage:
I won't agree with that because I recently changed my battery under warranty; January 2024 to be exact. So, my battery is relatively new compared to the average S23U user here yet I struggle to achieve the same results as a brand new phone. So, if we remove battery health from the equation, OS tweaks are to be blamed for poor battery life i.e. planned obsolescence.
[Samsung Galaxy S23 Ultra] darek5cro:
Okay, they changed your battery with new one (you wont know how "new" this new battery is, and you cant see inside because you will lose warranty if you open phone by your own) - if you are not satisfied with this new battery - ask for another replacement..

I had same problem with Note 20 Ultra when they changed battery under warranty with "new" battery (original Samsung box) which was produced 2 months after the release of the Note 20 Ultra, and I asked for a replacement after a year of half of use (so more than 1 year this battery was somewhere in warehouse/shelf) Who knows what they did with that battery, maybe they used it on other models for testing and installed it on my phone and billed it as a new one.

But fact is, i asked 2 times in total for battery replacement under warranty and none worked as well as the first one installed in the factory
[Samsung Galaxy S23 Ultra] OnnoJ:
This would actually support @amirage 's hypothesis, being also applicable for the Note 20 Ultra
[Samsung Galaxy S23 Ultra] amirage:
If the battery was replaced from the Samsung service centre, it should be "new" assuming that the battery was produced recently. However, as you said, it would be impossible to verify how "new" battery is unless we know the manufacturing date. But, assuming that the battery has not gone through the same charge cycles as the average user here, we may safely conclude battery drain is associated with OS tweaks than with the battery...unless we are both having a very bad spate of luck simultaneously ...
[Samsung Galaxy S23 Ultra] olafsand:
That's what i also afraid that battery's are more than year old. I don't think they produce new batteries anymore for s23u
[Samsung Galaxy S23 Ultra] Thanos88:
I haven't faced such issues, works perfectly for me.

Clear data & uninstall.

Make sure it's downloaded from app store.

Once downloaded, open, go to the bottom right, tap the 3 dots, click on "enable more stats"

Do the following commands in the poweshell window (make sure usb debugging is on);

./adb.exe devices (if your pc/laptop has successfully found your device then do the following command);

./adb.exe shell pm grant com.gsamlabs.bbm android.permission.BATTERY_STATS

Follow the tutorial within the Gsam app that appeared after you clicked on the 3 dots & clicked enable more stats. It will say things like "ok I've got adb installed" "ok I've enabled usb debugging " etc, at the end of the tutorial you should get a "success" message. As long as this success message appears, you've done everything correctly & shouldn't face force closing.

Let me know how you get on
[Samsung Galaxy S23 Ultra] Kinsman-UK:
Yup - got it this time after a wipe and uninstall of GSAM. Weird, as I tried this before. Can only assume something carried over from a previous backup. The only things I've done since last attempting it are a wipe of cache in recovery and installing the latest Samsung update. Thanks for your reply!
[Samsung Galaxy S23 Ultra] Thanos88:
You're welcome 👍👍
[Samsung Galaxy S23 Ultra] Paul_Deemer:
For those of you saying that all these extensive tweaks need to be made remember I got almost 11 hours with mostly stock settings. WQHD On, Motion Smoothness Adaptive, Adaptive Battery On, Performance Standard. Game Booster settings are still stock and havent been changed.

The Only real things that are different from stock on my Phone are 1) Chrome is disabled and using Samsung Internet, Gmail is disabled and using Samsung email. Samsung Keyboard was replaced with Googles Keyboard and finally 5G disabled and using 4G LTE.

Some of the stuff I have seen on the web indictate there is a problem with Samsungs Keyboard and it is causing a very bad drain as well as the Chrome browser. So if your battery life is bad first thing to do is get rid of both. UI 5.1 seems to be causing the battery issues so that can be fixed with an update.
[Samsung Galaxy S23 Ultra] Dinosaure42:
Looking promising ! Only lost a percent after 10m45s lmaooo that's insane
[Samsung Galaxy S23 Ultra] Thanos88:
Perfect, that's what I'm getting per 10mins. Only thing to look out for is standby Drain
[Samsung Galaxy S23 Ultra] Thanos88:
I lost 2% in 14 hours, not a major difference 😇
[Samsung Galaxy S23 Ultra] amirage:
Is GSAM still working after the recent update...It keeps force-closing for me. I even uninstalled/reinstalled it but to no avail.
[Samsung Galaxy S23 Ultra] amirage:
Why would Samsung keyboard cause drain? Chrome I can imagine, it's a synonym for battery drain but Samsung keyboard?? I'm tempted to use Gboard since it's far superior to Samsung's but I'll lose out on the OS theme
[Samsung Galaxy S23 Ultra] bala_gamer:
Best battery life from a Samsung flagship in recent times, loving it
[Samsung Galaxy S23 Ultra] Thanos88:
Yes still working. Clear cache and data and uninstall and then reinstall (make sure reinstalled from play store (
[Samsung Galaxy S23 Ultra] Thanos88:
You can use a dark theme on gboard too, it's not as good as Samsung keyboard theme but still does the job

The same keeps happening to me. Gsam will work for a while then crash. Some reporting no problems with it at all

Try to enable phone permission as soon as you install it, if that doesn't work then may have to wait for a developer update. I've updated my s23 to latest firmware and it works perfectly
[Samsung Galaxy S23 Ultra] robi101012981:
What tweaks should I do if I'm happy with those 6h SOT? As I've said, coming from S22 Ultra it's really an improvement.
[Samsung Galaxy S23 Ultra] darek5cro:
Yes. They are not producing new batteries for S23 Ultra anymore. So as new S23Ultras. Its only what is left in stock in warehouses. Why? Well, S24 is out for almost 6 months.. So buy new model for 1300€ and enjoy another year-two, or get used to bugs and average battery life after one year of using "old" model S23 Ultra.. You have warranty for 2 years, true, parts will be replaced with those they have in stock regardless of when they were manufactured and how they were stored. They are in the original packaging and you can't complain that you didn't get the original. You can only complain again and again that isnt working properly
[Samsung Galaxy S23 Ultra] Klaudas:
Ain't no way that battery lasts less after more than one year, major OS update and all updated applications.

Maybe new features, apps needs more processing power and battery?! Maybe that would explain why my 3 year old laptop is not performing the same way it used to 3 years ago?!
[Samsung Galaxy S23 Ultra] amirage:
Again..the contention is that Android since 9.0 or so was designed so that it would run on lower specd devices...low in ram and cpu yet be buttery smooth. OEM flavours are over engineered with a load of vestigial features that end up draining the battery...anyways...no point in cribbing about it...we've got to live with it...or take the plunge into AOSP

Does anyone know what this air command is and why it runs nonstop in the background? Thanks.
[Samsung Galaxy S23 Ultra] djoxie:
Air Command is connected to your S Pen, it automatically starts working when you take it out of your phone. If you keep your S PEN in the phone, check if it is put in properly.
[Samsung Galaxy S23 Ultra] Big Bread:
But even when I restart my phone and never use my s pen, it constantly runs in the background. I've checked, my s pen is always inserted properly.
[Samsung Galaxy S23 Ultra] djoxie:
Perhaps you triggered it somehow
[Samsung Galaxy S23 Ultra] OnnoJ:
Do you happen to have the setting 'Allow multiple S Pen' (or similar) under 'More S Pen settings' active? This will keep digitizer active even when S Pen is in its slot. Probably Air Command remains active too...

[Samsung Galaxy S23 Ultra] Klaudas:
Most ROMs, operators have option to disable it. For example EUX SM-918B
[Samsung Galaxy S23 Ultra] pratik_193:
Got it. In INS this option is not there
[Samsung Galaxy S23 Ultra] OnnoJ:
Well, not on my SM-S918B/DS with EUX in NLD.

There is also never a VoLTE icon visible in status bar. For sure all calls are VoLTE though, but as it is the norm nowadays, there is no need to show.

Is yours originally EUX?
[Samsung Galaxy S23 Ultra] amirage:
the VoLTE option disappears when I use an Indian SIM and it comes back on when I'm on UAE SIM. So, basically, Indian operators use VoLTE for voice and data

here's a trend that I'm seeing. People who are battery champions don't have IM apps installed and have Samsung internet as their go to browser...how do we less fortunate IM app users get closer to that figure? Whatsapp is an absolute evil in battery management...
[Samsung Galaxy S23 Ultra] Naikkon:
Edit. I googled
[Samsung Galaxy S23 Ultra] nmt1900:
I have a hard time in understanding how WhatsApp can be deadly on battery management. I even have 2 of them (both WhatsApp and WA Business) installed because of 2 accounts and do not see any detrimental effect from that. Can it be about some settings although I have not done anything special in WhatsApp settings nor set them to sleep?
[Samsung Galaxy S23 Ultra] nmt1900:
There's one thing about VoLTE - if operator does not have any 2G or 3G coverage then VoLTE is only way to make voice calls (beside VoWiFi of course). Many operators are dismantling their 3G networks and some do that even with 2G and with them you cannot have an option to disable VoLTE.
