My iphone 6 is turning off again and again
hi
yesterday i updated my i phone 6 with the apple latest software 9.3.5 after that my phone was taking so much of time to get 100% charge and the battery was draining very fast and when i woke up in morning i saw that my phone was switched off then i plugged in my phone but there was no battery charging symbol appearing i took it to apple service provider they told me that your phone is dead i asked what's the reason behind they were totally clue less i want to know how this thing can happen
being such a most valuable brand in the world you guys are totally clue less that why your device stops working suddenly i need a proper service for that i am not a fool who spent 60000 bucks on a device then after 16 months suddenly that device stops working and you guys are clue less about that
please revert as soon as possible
iPhone 6, iOS 9.3.5
