[Asus ROG Phone 6 / 6 Pro] TomKay:
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.
