Abnormal charging behaviour is very common issue in asus products. Atleast I experienced it in all my 6 devices like zenfone 2 laser, max pro m1 and m2 and several others. I think fault is in cable that they provide. Its also useless in data transfer. Little movement while data transfer causes sudden transfer failure and disconnectivity of device. They should improve USB cable quality.
