17.2.1 upgrade issues
I had the iPhone 13 and after upgrading to the new iOS 17.2.1 the phone crashed and was hanging all the time, so I bought the new iPhone 15 Pro and upgraded to 17.2.1 and my phone became slow, battery dies quickly, it takes me 30 seconds to be able to make a phone call, WhatsApp groups take 20 seconds to open, I literally can’t function on my phone. Please help me with a solution
