Bought a pair of iPhone 6 for wife and self 8 months ago, mine is fine, but hers drops wifi several times over breakfast and reverts to 3g (one bar so useless!) and has to be toggled to reconnect. So when listening to internet radio, her transmission/connection disappears, mine doesn't. Also her battery depletes on same settings as mine about 50% faster. Sounds like a case of repair rather than settings??
