So, i went to the apple store in my town to get my iphone checked. the display glass popped open and i suspect the issue to be a swelling battery. the guy at the genius bar, after running a diagnose, confirmed it's a battery issue, it's swelling and it may leak, not likely explode, but suggests to stop using the phone or replace the battery soon. the phone is out of warranty and i don't have apple care, so he offered to replace it for 80€. actually the deal was: at 80€ instead of changing the battery, we give you a whole new iphone 5. Now, i'm not a mouthful and not the kind of person who argues directly with a person, so i kindly told him, "i'll think of that, but i don't want to pay that kind of money on such an old phone" to be honest, the deal he offered is lame to say the least. the battery is the problem, but since it's under a special warranty condition, at the same price of the battery replacement, he will replace the whole phone (which normally would cost 280€). ok, but the rest of the phone works fine!! why would i want to replace the whole phone? what's the special offer?? i thought they would treat defective batteries in a different way, instead, i should pay the same price of a normal battery replacement... very disappointed.
