VP22 High CPU usage + battery drain: c2@1.2-mediatek

pparent

Hello,

On Vollaphone 22 . I think it happens since 24.04-1.2:

top - 00:01:38 up 10:28,  2 users,  load average: 23.18, 23.12, 23.07

It stays like that for hours, and eats a lot of battery unril I reboot.

1046 is an user in the Halium container, it's not so obvious to identify what it does.
Rather than top, I use htop (installed with crackle) to make it easier to see what it's used for. by looking at the other processes it runs.

I have no idea what kind of app is the one that is draining your battery and I dont even know how to check which app is draining my battery.
the only thing I know after updating to 20.04-1.2 my battery is not lasting at all.

Well it could help if when the battery is draining fast, you can go to the terminal and type "top", to see what program is using a lot of CPU.

I used "top -o %CPU" command, that you suggested "THANKS" and I realize that whatsnew app which suppose to be the upgrade of whatsapp web app is consuming all the battery, I am just waiting to test it for a full day and I will let you know tomorrow.

PS the icon of the new app is X11 icon, which someone asked me to check, his quote was: "Do you use one of the newer browsers, or any app that produces an X11 icon in the Dash?"

I just realize it is your project
I can be your tester.

Hum this is kind of strange as I don't observe anything similar. For me "Whatslectron" which is the process behind whatsnew, takes 1-3% CPU when in background (more or less the same that whatsweb consumed when unsuspended)

Question:

-What version of Ubuntu Touch are you using precisely? Stable or daily?

-When you use Whatsnew, when you go in the window carousel, do you see one ore two window corresponding to whatsnew, and what icon does it have under it?

-What is precisely the name of the process you see in top taking 100% CPU? Is it "Whatsnew"? "whatslectron"? Something else?

-Could you give me the result of "md5sum /lib/aarch64-linux-gnu/liblomiri-private.so" in your terminal?

UT 24.04-1.2 stable

Unfortunately, I uninstall the app and try to install the old one, I am not sure if it is still the case.
I am not sure but, I think that at the first install there were 2 windows in the window carousel.
Now I see 2 apps but after few seconds the second one is disappearing.
The icon is X11 Support.
The command in the top command list was and is whatslectron, before was at the top of the list with 100% cpu now is at the second place with 8% or less.
md5sum:
