My Asus ROG Phone 6 loses 5% battery life in 24h while just idling.

WiFi and Bluetooth are turned off. I don't have a SIM card installed yet, but even with a "Aeroplane mode" activated, I get the same consumption.

Is that consumption normal?

What irritates me is that in the beginning I saw horizontal lines in the "Battery usage" chart, indicating close to zero battery consumption when the phone was turned off. I don't get these horizontal segments anymore.

I installed GSam Battery Monitor and it shows 100% time spent in Deep sleep (but shows a "5% / 5%" for "Discharge Screen Off"). In the "OTHERS" chart, "Doze" is a continuous line but "Active" shows a lot of interrupted small blocks ("Screen" is obviously completely absent). "Wifi" is shown as always on, but I believe that is a bug because I turned off the location-based features that turn on Wifi automatically, turned on Aeroplane mode, etc. After a restart, the "Wifi" bar was correctly absent for a while but briefly turning Wifi on, got it back to "always on". I'm 99.9% sure this is a GSam bug.

I have double confirmed with "DevCheck" that the CPU goes to "Deep sleep" and spends pretty much all the time in that state.

I get about "5m" combined App Wakelocks in 48h.
The biggest battery consumer is "Kernel (Android OS) 7.5%", followed by "System (*wakelock*) 2.3%", "Google Play services 1.6%". These figures are from a 14 day period in which I used the phone for 3h to play a game (6.7% consumption) and otherwise only turned it on to check the battery. I currently don't have access to the percentage figures during pure sleeping since I plugged in the phone for charging.

Using GSam Battery Monitor, I don't see any app wasting battery life in the background. It's the kernel that consumes the vast majority of the battery life, if the phone is idle. The Android/Asus Battery usage stats show "Phone idle" with 54.7% for that 14 day period. The next one is the game with 3.8% (played for 3h) and then there is "Screen" with 1.9%.

I'd understand this kind of idle figure if the phone had a SIM card installed and bad reception but as I said before there is no card in the phone yet and the consumption is the same if I put it in Aeroplane mode.

I'm running Android 12, build 32.2810.2212.241.

The battery "system mode" is "Dynamic". The refresh rate is set to "60Hz" (not that it should matter with the screen turned off all the time). "Battery Saver" in the "Developer options" is turned "on".

I'd be grateful if someone could comment on the 5% battery life loss within 24h. I realize that many will not be able to compare this with their figures, as they'll have a cell phone service running, but perhaps those who turns on Aeroplane mode, should have comparable figures, for an 8h period, or so.

My Huawei Mate 20 (running Android 10) shows pretty much no consumption at all over night via the battery stats, when I turn on Aeroplane mode. Perhaps it loses 1% or at most 2%, I'll check again. Should the ROG Phone 6 behave the same, or is this difference to be expected?

Again, I'm irritated that I definitely saw multiple horizontal (no usage) periods in the battery usage chart in the beginning. I'm pretty sure these appeared before I had given the phone a full charge yet, so perhaps they weren't really indicative of close to zero consumption due to a lack of battery capacity calibration.

0.2%/h is a very good result.
I'm not so sure.

First, remember that this figure is without any cell phone service drawing current.
Second, I initially saw segments of the battery consumption graph that were horizontal, but no longer do.
Third, look at what Thanos88 reported.

I've seen other posts about unusually high idle consumption of the ROG Phone 6. I believe most users will not even notice because they don't shut down their phones fully and the idle consumption disappears as noise under the all the higher normal consumption. Perhaps other users don't complain, because they don't suffer from the issue I seem to be having. I don't know.

android 12

.197 firmware

Done plenty of app debloating
Thanks!

I note that you are not on the latest version (.241). That could explain the difference. Perhaps I saw the near to zero consumption before I accepted the update to .241? That is quite possible.

I've done a lot of app debloating as well, removing Facebook, etc., but as I mentioned before, there are no apps that cause any noteworthy battery consumption. Did you do anything out of the ordinary? I first just uninstalled and/or disabled some apps/services that I did not need and later even uninstalled some via ADB. The latter made no difference regarding battery consumption.

My 5%/24h figure comes from

41.3% Android System
15.2% Kernel (Android OS)
4.4% Phone Services
3.5% com.android.systemui:screenshot
3.1% Google Play services
2.0% com.google.uid.shared:.....
1.9% GSam Battery Monitor
0.9% ASUS Launcher

There are some more (e.g., 0.4% Gmail) but they don't use much at all.


Time Held Awake (over a 37h period):
Kernel (Android OS) 10m 53s
Android System 4m 1s
Google Play services 16s
com.google.uid.shared:..... 2s
com.android.systemui:screenshot 1s

That's all, no other apps/services are reported to keep the phone awake (while it was idling).


Number of times Waking Device
Google Play services 48
Android System 34
Calendar Storage 8
android.uid.calendar:..... 7
com.android.systemui:screenshot 6
com.google.android.partnersetup 5

There are a few more, but the next one has a figure of 3 and the rest are all lower.

No network data used (no SIM card, Wifi turned off) and no location used either.

I note that further battery consumers were sensors used by

Dirac Control Service 13m 5s
Android System 1m 17s

I do not know whether this is normal.

Is it possible to revert to the .197 firmware (or whatever firmware version my phone originally had) by performing a factory reset?
Or does the latter just clear all user data but leaves the current firmware in place?
In the latter case I would have to flash the .197 firmware manually, correct?
Would the latter be safe regarding warranty, etc.?

I don't want to root the phone or anything like that, I just would like to avoid unnecessary battery consumption.

Try to force stop and clear data & clear cache of Google play services , then reboot your device , charge to full and then see what happens

Thanks for the tip! I've done that before, without the "charge to full". I can try the exact sequence you have described.

Given the usage figures, Google play services are not using much:

Just
3.1% Google Play services

compared to

41.3% Android System
15.2% Kernel (Android OS)
4.4% Phone Services

Are you saying that either Google Play services are using battery in a way that GSam does not catch, or that Google Play services somehow responsible for the high system consumption?

I would say Google play services is causing the issue. Also I forgot to mention, make sure you force stop, then click "uninstall updates" on Google play services, then clear cache , then Clear data then reboot your phone.

If that doesn't help, I highly recommend you dow load BBS (Better battery stats) , give it adb permissions, and monitor your battery life/wakelocks with that app

I followed the steps you described (including the "uninstall updates") and will report results, once the phone has fully charged and has idled for 24h. If there is no change, I'll uninstall GSam and install BBS.

Thanks a lot for your help.

Sadly, clearing the data&cache of Google Play services and downgrading it, did not help, at least it does not look like it helped right now.

This time, the battery lost 6% in 30h (went from 100% to 94%).

The last few hours showed very little battery consumption, though. Perhaps there was some book keeping to do after reboot which caused some consumption up until very recently.

I'll let the phone idle for another 24h and see whether the flat period continues. It would be awesome if it did.

I let the phone idle for another 24h and even though I restricted battery usage for more apps/services, the idle consumption did not change.

I'll try Better Battery Stats now.

That's odd. What's your software number?
Android 12, build 32.2810.2212.241

Three updates more current than your .197 version.

I would have thought that if Google Play services were at fault, GSam Battery Monitor would have showed that. But perhaps not. I'll see whether BBS will provide any better clues. I could also try to disable Google Play services (just for diagnosing purposes), but I'm not sure that would result in any useful data, as many apps complain, if one disables Google Play services completely.

I suspect the difference between your idle consumption and mine is the firmware version. I've disabled/restricted so many apps/services, I doubt the phone would run normally now. So far, no culprit has been identified.

It's going to be the firmware then, or maybe even an app you've installed. I'm currently on 44% battery, with 9 hours 41 mins SOT, 1 days 2 hours off charge

I think I can exclude any user apps, since,

1. The issue is the same if I start the phone in "Safe mode" (disables all user apps).
2. GSam Battery Monitor would have reported high usage by an app.

The battery consumers are the OS and motion sensors.

I turned off "Lift phone to check" (or similar) and the phone indeed does not activate the lock screen when I move it while the screen is dark. The phone stills faintly shows the fingerprint area if I move it, so some motion detection must be going on. I don't think this behaviour can be disabled, or can it?

The fingerprint motion can be switched off in the settings however, it's probably the firmware that's causing the main issue imo

    That's great!

    What build number of Android OS are you running?

    I'd be grateful, if you could check it and post it here.

    Have you done anything to get this performance or is it "out of the box"?
