My go-to resource for comparison of phones' battery life is GSMArena's Battery life test results. [1] I customize usage pattern to 1h calls, 3h web browsing and 3h video playback (I don't watch much video on the phone, but I believe that power consumption of Skype, GPS navigation, etc. should be somewhat similar) I feel that today's phones are way too large, so I limit my choice to non-huge ones. So far, last year's Sony Z3 Compact tops the chart: 44% better battery life than iPhone6s in my 'heavy usage' scenario, 63% better in the default scenario. I'm eagerly awaiting the results for the recent Z5 Compact: it might provide even better battery life (72.5 hours compared to 'two and a half days', as tested by The Guardian [2] [3]).
