I'm trying to find out how the Restricted works and how can I really prevent apps from running when not needed.
My recent observations/test so far:
When set Spotify to Restricted and put it in the background it doesn't stop immediately, but let's say after 3-4 min. I guess this is normal despite being a bit off from my expectations.
Most of the apps I put in restricted battery mode but despite that, I get notifications from them without opening/running them. Today I was surprised when Skype started ringing on my phone simultaneously with my laptop when I was expecting calls from my parents. I intentionally did set Skype battery mode to restricted and ensured Skype is not allowed in "Alarms and reminders" under "Special app access". Why then Skype was running in the background and how I can prevent such with other apps?
