Best Smartphones — every ranking, by use case and budget

We researched every phone against its official specs and the consensus of the reviews we trust most (GSMArena, Tom's Guide, PhoneArena, TechRadar, Android Central, Macworld, Consumer Reports, Forbes and others), then scored it on the same rubric. We have not bought and lab-tested every unit ourselves; scores reflect what each maker states and what independent reviewers measured, weighed against each other.
