I have the iPhone 7 and I am wondering if I should upgrade from 12.4.1 to 13.1.2 because I read that it is to buggy. Another random question is there anyway I can I inprove the battery life on my phone because I went through all the apps and turned off the background app refresh and cellular data and it still goes down also is it normal for the phone to feel a little warm when it charges and it takes forever to charge
Thanks
