Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that screen brightness affects smartphone battery life?

Yes. A reference work states plainly that showing a bright screen uses more energy than a dark one, which drains the battery faster. Several battery-modeling papers also list screen brightness among the factors that accelerate smartphone battery depletion.
