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.

X Vario test data on DxO Mark D7000 test data on DxO MarkVery good image quality; Better than average noise vs. detail handling at high ISOs; Very good dynamic range in JPEGs, excellent in RAW files; Lots of high-end features in a relatively compact body; 6 fps burst mode.
Viewfinder not as accurate as specified; Viewfinder doesn't show ISO unless adjusting; No live histogram in Live View mode; No phase-detect Live View AF mode.
Outstanding design and build; Exceptionally sharp 28-70mm equivalent zoom lens; Very good still image quality with accurate and realistic colors; Fairly speedy and accurate autofocusing.
Expensive, especially for a fixed-lens compact; Relatively slow f/3.5-6.4 lens; Below average video functionality and quality; Not at all pocketable, about as big and heavy as a mirrorless camera with a moderate zoom lens attached.
