In the era of discounts and cashbacks, one of the most commonly used and abused word is UPTO.. Get upto 80% discount and 100% cashback (*max discount & cashback Rs.50 😛 )

ASUS seems to have decided to take this concept and run with it. Not just does it’s latest Zenfone 3 Max off upto 3 days of battery life but it also offers upto 5000mAh battery as well. What does upto 5000mAh really mean? Well, your guess is as good as mine.
