Paid just under $200 to replace my cracked iPhone screen. Days later, my iPhone 6S (less than a year since purchase) battery loses its charge in less than ten minutes.
When I asked for assistance in store, the employees claimed that the loss of charge is unrelated the the screen I purchased. Neither the employee, the technician or the manager would admit the the loss of charge and screen replacement are linked. To the point that they told me my logic is flawed - I left the store unimpressed and insulted.
I don't suggest going here. Just go to Apple for the service your phone deserves. It's worth the price.
