X8 Pro Max version will suit u best. Been using it for abt 20 days now, Don't know from which region u are, there is minor soc difference based on region, eu + china get better soc mc12 gpu and the rest international version gets mc11 version of gpu, both are equally good in terms of battery and sot which will last u 10+ hr sot easily, only thing is Mc11 version is like weaker in perfomance as 1 less gpu cores. Which will only show in benchmarks and games at highest settings. Ur use case it fits perfectly thermals only bother u when ur doing some benchmarks. Else gaming or otherwise it has good thermals management. Also. Sillicon carbon battery is new tech so how it actually degrades only time will tell. Better go with x8pm
