I bought Xperia XA Dual (F3116) with product ID: [protected] on 25/08/2016 from sai electronics shop no. 28, B&E DDA market, Dilshad garden, Delhi 110095 and got to know that the phone has major battery drainage issues. It gets discharged even without using it. It runs for 3-4 hours only on average usage and it takes longer time to get fully charged although the company promises fast charging, it also hangs. Camera is also below average. Please look into the matter as soon as possible and also i would like to return the product and get a refund. i want my money back. i feel duped
