Hello, I hope we will find out what causes this terrible (up to 15%) battery drain we get after our phone is sitting in idle through the night. Some people also write about this kind of software issue even when they are in airplane mode without WiFi. Let's check this out! Share your ideas and results My setup for the night is 2G (4/5 bars) with data on + connected to WiFi 5GHz full bars. Night shift is turned on by default every night (based on time). Spotify is mostly disabled, no Hey Siri and so on. Only weather and notes can sync in the background.
