I charge my Pixel 5 pretty infrequently, couldn't give a number though. I leave it in battery saver mode automatically when it's below 70%, and often I will just plug it in to a quick charging cable (the one from my steam deck actually) for 20 minutes to "top up" (may not fully charge but who cares). I only notice my battery life about once every other week. Other than frequent photography, I guess I don't do very much intensive processing on my phone though.
