You said 'modern' versions, and yet, you mention a mirrorless battery issue of the past. All the major players have resolved this issue in all releases in the past 2+ years, soon eventually to be the distance past.
I get over 1000 shots out of a battery in my Nikon. Barely 200 out of my Olympus. (Reminds me to put its battery on charge!) Anyway doesn't affect image quality one way or the other - I never suggested it would!
