High end gaming and mobile gaming do not go in the same sentence. People don't understand specs don't mean SH*T if there is no cooling method or ventilation put into these devices. It could have all the 2.6ghz quad core snapdragon 1000 processor with 4gb of ram and 1tb of memory. Without anyway of cooling or ventilation you will yield 10-15min of "high end gaming" until the device feels too hot to handle so you will stop or the device stops itself from becoming too hot.
Phone specs look great on paper. What lacks is high end software for the high end specs and no cooling or ventilation. What's the use of a 800hp muscle car if there is zero ventilation to the engine???
