iphone spinning circle next to WiFi
Fighting this literally for months and my only solution was a restart until this old answer from "deggie"... "Don't do the restart and let it run. After about 24 hours check your battery usage and see which app is using the most battery, that will be the one spinning the wheel."
It was my "Brave" browser. Removed battery eater "Brave", went with "Firefox Focus", spinner all gone!
Thank you deggie!
