So long story short on Saturday, I got a replacement Iphone free of charge from the Apple Store due to a wifi hardware problem but now I face more problems... I woke up the next morning (Charging over night) to find the battery was still on red even though it was plugged in all night.. I thought maybe it was the usb lead so tried restarting it and plugging it into computer for a few hours, all seemed okay. Then about 3-4 hours later, I received all of last nights and this mornings texts.. It was like they didn't come through cause it was on charge.. Anyway, came home today and battery was low, Plugged it in charge about 3 hours ago but its still on red and I have asked people to try ring/text me and I have not received anything even though they are certain they have.. Any tips? I have tried restoring and restarting but no luck..?! I don't really want to make another trip to apple store! Thanks!
