The thing is I'm the hottest person and I need a hot phone. Okay jokes apart. The phone heats up like furnace and I'm always feeling the heat because of the climate. But on deep analyses once the heat raises above 36c the 810 was throttled and heat raises slowly. But a simple use, the phone easily raise to 30-35c.https://forums.oneplus.net/threads/one-plus-2-heat-issues-review.348417/
Damn thing heats up like a furnace. And then you also have the Indian climate. Put the SD810 together with Indian summer and you are effectively holding a frying pan in your hand.
Better to go for X Play or Style, even the Nexus 5 will work better here.
