This is not necessarily a drainage problem, but after the latest update (4.5) CPU sleep has been acting like a roller coaster. This is the last 12 hours with mostly idling (a little bit of browsing on this forum and such at around clock 19.00, which really doesn’t show):
This has happened since, and it happens all the time. Looking at htop or Lighthouse nothing particular seems to pop up. My configuration is pretty basic (on Xperia 10 III). Only calendar syncs to Nextcloud, but even that is set to manual.
