Fairphone 3+ performance issues with /e/OS 0.16-20210422111920

this is an older thread and @watertable probably switched phones.

From another thread I looked how I’d programmatically measure startup times and put it into [HOWTO] Benchmark App Startup

I think profile Apps (Island/Shelter) do have considerable overhead, but I’d need to measure to speak to it. Also time-to-user-interaction is not the same as fully-drawn if it is a splash/loading screen. I don’t know yet how to measure app-switching.

I extracted your timings for other FP3(+) users to compare to:

  • installed Island to run WhatsApp and Telegram on the work profile, Switching to any of the Island apps can take a good 5/6 seconds
  • Spotify: 15 seconds “for it to start and stabilize”
  • Magic Earth can take 5/6 seconds to load
  • Brave: scrolling stops and I have to take the focus out of the app and come back to it in order for me to be able to keep scrolling again
  • Taking a photo (in normal mode, no HDR or anything) can take a good 4/5 seconds
