Zenfone 9 Battery Drain by "Others"

[bLackShadow7]

Hello,
I have just bought a Zenfone 9 last week and I am having bad battery life. The SOT is roughly 3 to 4 hours. I can see most of the battery is consuming by "Others".
Is it normal?
Model Name: Zenfone 9
Firmware Version: 32.2050.2050.34
I am really disappointed with the battery performance so far.

Thank you

You can enable the log and let the battery drain for a bit before stopping the logging tool.

I've got the same issue, too...

@Mansi_ASUS I was able to identify at least one cause of this "others" drain, can you pass this to the team?

Here's 18% drain, and looking to the logcat log I can see the following:

So, it's a vendor.qti.camera.provider process eating CPU, which I confirmed with the 'top' observations:

PID USER PR NI VIRT RES SHR S[%CPU] %MEM TIME+ ARGS
1897 cameraserver 20 0 15G 4.0M 4.0M S 23.3 0.0 862:40.01 vendor.qti.camera.provider@2.7-service_64

vendor.qti.camera.provider is at constant ~25% cpu, I've waited for some time to ensure that it's not a fluke/spike. Device was with screen off and of course camera is off. I don't use camera much, so was able to catch this only once. Hope it helps.

PS: I've posted the same reply yesterday, but can't see it on the forums 😞

@Mansi_ASUS, I was able to pinpoint at least one "others" drain cause - here're my battery stats with 18% "others" drain:

Now I look into 'adb shell logcat' log and see the following:

So, it's a vendor.qti.camera.provider process eating CPU, which I confirmed with the 'adb shell top' observations:

As you see, camera.provider is at constant ~25% load, with the total time exceeding systemui/system_server. I've waited for some time - and this isn't a fluke/spike. The phone is with a screen off and camera hasn't been used for some time.

I don't use camera a lot, so caught this but just once. Hope this helps.

I can see constant high CPU usage (~30%) by android.system.suspend@1.0-service. Other processes thermal-engine-v2 and system_server are also using a few percent of CPU all the time.

ADB is connected over WiFi, phone is not connected to USB/charger, screen is off.
