This ranking combines two scores published by Picksly: the Battery score, based on public measurements, and the Smart score, which rates value for money. The price is the best new price checked at retailers, dated.
Ranked by the average of the Smart score and the Battery score, among 3 smartphones up to $800 with a verified offer. Smart only counts new devices scored at least 50 out of 100.
7 other models up to $800 score under 40 out of 100 for Battery: they are not suggested for this use.
