I don't remember any complaints about the battery life of D3x00 or D5x00 users Or Z50 users... other than the general complaint, that battery life with any ML camera is way shorter than with a DSLR (naturally).

There is simply no space in the Z50 body to hold an EN-EL15 battery.

Besides: "The change from Nikon's standard DSLR battery is also another inconvenience"... it's an inconvenience you have with any single-digit Nikon DSLR since the D1, too
