Since updating to android 11 the phone has been awful in several ways and its gotten to a point this week that it is often so hot it is painful to hold. I've cleared the cache partition, but it hasn't changed. Since the update my WiFi disconnects randomly throughout the day, however is fine on every other device I am using. It has gotten to the point that I mostly leave it turned off as I have unlimited data, however I have things that I can only do over WiFi so it is required. My battery barely lasts, im currently using over 200% a day so I frequently have to charge it, but the phone gets hot when in use not necessarily when charging. The phone was absolutely fine prior to android 11 and I don't know how to fix this.
