I'm having confusion between Realme 2 pro and Asus Zenfone, because Asus has got a massive battery (5000 mAh) and (Snapdragon 636), whereas Realme 2 pro has (Snapdragon 660), but a very low battery (3500 mAh) considering the processor. And I specifically want to buy a phone for gaming (PUBG, Asphalt 9 etc).
