I got this device recently. Asus has done a very good job this time. They made a phone with a massive 5000mah battery which is mind blowing. And I’m using this device, and amazingly I didnt find any lag till now. It has a qualcomm quad core chipset which is flawless in my opinion. It has a asus Zenui skin on the top which very fast and fluid. I played asphalt 8 and modern combat 5 and this device didn’t even heated up. Talking about the design, the design is awesome in my opinion, very slim and sleek design eventhough it has a 5000 mah battery inside. Taking about the battery in this phone, hmmm. we should’nt talk about that coz its got a 5000 mah battery capcity. Even I recharged it only once when I unboxed this thing and right now it has 85% juice left. Even you can use this device to charge other phones. That’s preety Dope feature. Bottom line, If you want a power and performance packed phone then definetly go for it. Its my personal recommendation. Dont think something else just go for it.
