I had my Iphone 4 checked here cause I was getting NO CHARGE at all to my phone. John did a few checks and then said it was the battery, he changed out the battery in less then 5 minutes and there it was my iphone was completely back up less fully charged but in working order. John the owner was super professional, friendly and knows what hes doing! Im sending all my friends and co-workers here! Thank you IPHIX. Definetly coming back here if I have any other issues with my smartphones...
