@mario-ch I know what you mean but e.g.:

Jan 27 - 13 commits
Jan 29 - 13 commits
Jan 31 - 17 commitsNo chance to recognize when the change was made.

After discussing here, my Xperia X just went down to 20% in just 13 hours
Do you have apps that is always running on your phone? Mine is usually TELEports and Pesbuk. -
Recent changes of CPU governors related to suzu:
Jan 22: https://github.com/fredldotme/device-kernel-loire/commit/2feb357a3e4a605b687cef3d3d6c572ae11cb9fc
CPU_QUIET_GOVERNOR_RQBALANCE:
This governor will scale the number of CPUs online depending on both CPU load and the number of runnable threads with careful but simple and precise calculations.
CPU_FREQ_GOV_SCHEDUTIL:
This governor makes decisions based on the utilization data provided by the scheduler. It sets the CPU frequency to be proportional to the utilization/capacity ratio coming from the scheduler. If the utilization is frequency-invariant, the new frequency is also proportional to the maximum available frequency. If that is not the case, it is proportional to the current frequency of the CPU. The frequency tipping point is at utilization/capacity equal to 80% in both cases.
Maybe @fredldotme could bring back availability of previous default governor, I'm not sure if it was "interactive" or what. Then we can try to test it via command:
echo "interactive" | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor -
I got mixed responses from the recent Xperia X work. Some say battery life has improved, now some claim it got worse. Generally those who got worse battery life had suspension prevention enabled in some apps.
@c4pp4 I'm not sure that schedutil is at fault here. Also we need it as it sets CPU frequencies in a kthread context, which is required for some mutexes to work correctly and not drag down the system into a panic.
You could try reverting this commit locally and see for yourself if it's due to the way the CPU is actually idling: https://github.com/fredldotme/device-kernel-loire/commit/84d9466cc10cc869b3a19086208cf4c6c59ef9b0
IMPORTANT: You will lose the ability to get notifications on time.
I'd rather suggest not using suspension prevention in UTTT as that's not a supported configuration for exactly this reason.

@fredldotme
Can you describe how they are using the phone so the battery life has improved? I'm not using UTTT at all. Wi-Fi OFF. Data 3G ON. I have Dekko2 and TELEports installed. I'm using Morph and listening to the music. Anbox is off. That's all and I'm "happy" with 12 hours. Unfortunately I have no hardware to build the test at the moment.
Idle test from full charge: Wi-Fi OFF, Data OFF, two active SIMS, display turned OFF all the time, after 12 hours it's on 80%. Is it OK?
I'll take a notes about phone using (time and task) and try to compare it with battery usage graph and let you know.
-
@fredldotme Stable channel OTA-16 and I've reinstalled all my apps for sure. It looks like Morph browser (and maybe some other apps?) is eating more battery power (javascript sites?). On the other hand I've noticed better system response. I think it's the result of the governor changes. Without using Morph too frequently it lasts quite a long in my case (cca 20h). I think it's a great work after all. I will be monitoring usage again and when I find out something new I'll place a note.
-
@c4pp4 cool
-
As I mentioned before, the more consumption of the battery, is not a serious problem for me. Because I think that if the changes made contribute to a more stable and secure system, that is more important to me. Thank you for your work and the 'commitment'. I wish you a happy Easter.

Lately, the more battery drain is more apparent on my Xperia X. The drain happens on idle. I get around 20% drain overnight with wifi turned off. I have Dekko and Ubsync though, so perhaps those have impact too.
-
@kugiigi Data on?
-
Well Ubsync is a solution that inherently wakes up the device more often by nature. Can't have syncing without waste of battery life.
-
@c4pp4 No, but there's a sim card.
@fredldotme Yeah that is true. I tried stopping the UBsync service but it's still the same. Maybe I'll try fully disabling syncing and trigger syncing manually
-
@kugiigi was that recent battery drain on devel? One of the reasons might have been nfcd looking for an NFC adapter every second. It's now not looking for an adaper anymore as it's been disabled for Android < 9 devices.
-
@fredldotme No, I'm on stable. But thanks for the information.
The drain is still there. It's most likely UBsync's fault because it's the latest app I installed I'll just try to uninstall it and go back to manual backing up to my NC
