Hey, thanks. Yes, I can confirm that. Since a few days I noticed qml-phone-shell taking up 30% - 40% CPU too. Haven't yet seen maliit-server doing that on my phone.
I've been thinking about some small daemon that would collect CPU times of apps and send that to some stats server in an automated manner. I think that would be very useful. Shouldn't be too hard to create some snapshots every x seconds and send collected reports to a server once a day or so. There we could create stats on which binaries use the most CPU and get a good feeling where optimisation is needed. In a second step this could also include crash traces and such. Of course this would need to be an opt-in feature. What do you think?
