Thinking about coming from iPhone 15PM, what’s the battery like on the normal 9pro vs 9Pro XL

I know you’ve all heard it so many times before.. want to join pixel but not sure about a few things..

Is the battery better or worse vs iPhone 15PM?

Is the battery much difference between the normal 9pro vs 9pro XL? I can get a normal pro with more memory for same price as XL with less memory..

Does the phone charge quicker than an iPhone?

I’ve tried researching on YouTube but no one really explain or does fair tests!

Plus any other info would be great…
