There is a demand for enduring battery life for our mobile devices particularly smartphones. As a traveler who’s usually on the go, there isn’t always a chance to charge our smartphones especially in transit. Asus Philippines gave us a chance to try out their latest battery power behemoth, the Asus Zenfone Max ZC550KL. The Asus Zenfone Max boast a 5,000mAh lithium-polymer battery boasting a 38-day standby time. While I haven’t full tested its standby time, I had the Asus Zenfone Max gone through the demands of travel on a festival weekend in Cebu.
