After I bought rog phone 2 from flipkart in India battery was good for almost 2 weeks. Then the battery started to show abnormal drainage. After a month of use the battery of 6000mah doesn't even lasts for 3 hours of playing games. This battery of Asus rog phone 2 feels like 3000 mah rather than of 6000 mah. I think many like me has started facing this issue in this phone. I hope Asus will look into this issue asap and fix this drainage issue is next update.
