Idle battery drain -prevent sleep by Assistantdelay

[efitko]

Hi everyone,

I've been dealing with idle battery drain for quite some time. Overnight, I can lose up to 40% of battery. I’ve done two factory resets, wiped the partition cache—nothing helped.

I installed GSam Battery Monitor and noticed that the phone doesn't enter deep sleep due to “Prevent Sleep by AssistantDelay.”

Using PowerShell and ADB:

while ($true) {

  adb shell dumpsys power | Select-String "AssistantDelay"

  Start-Sleep -Seconds 3

}

I see various native Samsung apps appearing, which I’d prefer not to disable. When I tried disabling one, another would activate in its place, and it kept going like that.

I’d really like to understand what’s causing this. I assume it’s a software-related issue, so sending the phone in for warranty service would likely be pointless.

I’ve disabled both Bixby and Google Assistant/Gemini.

Can anyone help me figure out what to do?

Also of note, I downloaded that app you mentioned and noticed my phone telling me it was always running in the background. So there's a chance the battery measure app is preventing sleep.

Also to sum up that link, they suspect it's edge lighting. Though with a command you can find out which app is doing it.

Keep us posted with your findings.

I’ve already studied all of that… And as I mentioned above, if I disable the app via ADB, another one appears in its place. In my case, it has nothing to do with Edge lighting. Here’s an example:

Gimme a few days to try things on my own device

As of right now, I suggest using the send feedback button within samsung members, writing the important details with screenshots if needed and seeing if something happens. That feedback should go directly to devs. Seems this issue might go back to the s23 or older

I’ve already sent it—curious to see if I’ll get any response.

You'll get a "thanks for letting us know" initially but eventually someone does see it. It's just if they have the power to fix it or understand the problem is the issue

Hi.

I don't understand why people try to mess up their phones when the newer phones are designed to sort them selves out by learning user usage habits with help of AI.

Without going to technical.

Here is my take.( If you haven't done already).

1. If you Factory Reset your phone.

A) Don't transfer/recover apps or settings.
Photos etc can be recovered either by smartswitch or if you have a cloud backup like Google One etc.
I'm presuming you do have a good backup in place.

My experience has been incompatible apps and settings are the common issues for abnormalities like yours.

2. My personal overnight drain is around 5% which I feel is fair .

3. I never use any third party battery apps as they themselves needed resources to run. The inbuilt one is quite capable.

4. If you like dabbling with adb and stuff you are better off asking at xda forums as there are more technical people there who can guide you.

This is more of a consumer/customer forum and we don't advise playing around with adb if you don't know what you are doing or getting into.

Either way. Hope you find a solution to your problem.

Also as you rightly pointed out messing with one app will have a knock on effect Other apps reliant on that app and mess up the fine tuning.

Have a bit of an update. I'm seeing the same wake message yes, but it's not affecting my doze.
(rounding occasionally) For stats, held awake for 1h 2m with 17m of deep sleep. So the device has been recording for 1h 20m. 17m of that time was total cpu off. (not off but you know what I mean, cpu in a sleep state and not really running)
In the 1h 2m it was awake, 30m was spent in light doze and 44m spent in deep doze. Those do not add up so assuming overlap or cpu sleep occurred in deep doze. So the phone spent 4% of it's time awake not in any doze mode (as recorded by that app, not my maths). My screen has been on for 6% of the time as well.
So from what I'm seeing right now on my own device. Doze is always on in mostly deep doze while the screen is off, the assistant wake isn't preventing doze from working while yes it has gone off 20 times by now.
Have to wait for tonight to get more data, will charge to around 80%, leave it overnight and not charge it as I usually do as I sleep. Then I'll look at the doze data and battery usage

So @efitko have a look at the doze section of that app. Yes you might see the wake 2000 times but look if the device is actually waking up or not. As again, with my testing, the device stays in doze even after the assistant interrupts
