iPhone 6 Bluetooth Range Problem

I'm having bluetooth issue with my new iPhone 6. The range/distance seems to be very much smaller than with my old iPhone 5. I've tried with two different bluetooth headsets and with either one can't go farther them 5 feet / 2 meters using iPhone 6 without dropping bluetooth connection. If I pair same devices to my old iPhone 5 I can go to the different rooms and still be able to listen to music, answer the phone calls etc. Anyone has the same issue?

Thanks
