Hi, i have updated iOS from 14.8 to 15. After that i am facing issues like so many apps are lagging. Those were working perfectly fine on the same day prior to update. IPhone storage is taking 3+ mins to load completely. Apple store is taking couple of secs to load. Iphone is getting extremely heat while using. Charging is also taking longer time. Chat with apple support team, as per their suggestion, updated iOS again using my pc. Still getting the same issue. They are also suggesting to do factory reset as well. Why would i do factory reset and restore again. Just downgrade it to iOS 14.8 again.
