Bluetooth in iphone 5S is worse than the 4. Connection to devices sounds like a cd skipping.

my ipad doesn't have any trouble connecting, but the phone skips, and sometimes silence for 20 seconds, or just stops altogether. I just bought a new car with bluetooth technology. The ipad can connect and play, but the phone is a sketchy connection. I'd prefer to use the bluetooth in the car for phone calls but when I do, it sounds very crackly. I also have a motorola wireless headset I wear at the gym or when walking. the connection is spotty and makes it difficult to enjoy. i just bought the phone a month ago and it is on 7.1
