Are all iPhone 6s devices charge slowly or only the 16 gb variants ?
I had this slow charging problem from the first day , I thought I will go for repair before the warranty finishes . So , I was there at Apple service centre and told them all the problems . Main reason of me going there was slow charging . And another problem was mute button not working . They took 4-5 days and gave me a new phone ( thankfully) but the slow charging problem is still there with me in the new device as well.
