Running navigation in the background with closed app
Two days ago I was checking a route in ABRP and then I closed the app. Yesterday I noticed a high battery drain, not knowing what was up I closed all apps on my iPhone. Then I heard a navigation prompt about turning left. It was weird as no app was open but it was just this one thing and theb stopped. The battery drain still was high though. Today the drain was still high and as was going out I heard the navigation prompt again. No app open apart from messages and such. I then thought about ABRP and as I opened the app, the route navigation was still there guiding me. I checked location info and yes, ABRP was using location. Is it possible for the app to run in the background even if it’s completely closed? And use location? How?!
