If you haven't upgraded to MacOS Ventura and are considering doing so, from my experience so far I say don't upgrade. I upgraded my MacBook Pro which I bought new in April to Ventura on the day it was released. Performance is fine, but battery life is significantly less. To test, I started it in safe mode, and let it sit without my touching it for a couple of hours. The battery level dropped almost 30% during that time. I spent some time chatting with Apple's tech support. After about 45 minutes of trying different things, they said to let it go for a few days to see if battery life improves. That was not a good sign. Here it is now a few days after that, and I'm running my test again. The battery level is still dropping just as fast. It has dropped 3% just while I'm typing this response, and I'm not typing it on the MacBook. Don't upgrade!
