Cameras with longer battery life can take more photos before exhausting their batteries.
Special note: The measurement standard for battery life stipulates that if a camera has an internal flash, it must be used for 50% of photos taken. For this reason, comparisons of one camera with an internal flash to another without will not be comparable
Maximum effective ISO is an estimate of the highest sensitivity at which a camera can capture excellent quality photos.
Cameras with higher effective ISO will be better choices for indoor photography, night shooting, and indoor sports photography, especially if you intend to make large prints.

G1X Mark II test data on DxO Mark GF3X test data on DxO MarkWider, longer, faster lens than predecessor, with good overall optical quality; Faster AF performance; Closer macro shooting; Built-in Wi-Fi and NFC with remote shooting; Decent JPEG burst performance; Excellent build quality.
Localized flare issue when wide open; No real net improvement in image quality over predecessor; Slow burst mode when shooting RAW files; Poor battery life; Video quality is so-so (not like Canon DSLRs).
