Got a Brand new Iphone 5s on contract with Vodafone via Phones4u - noticed battery life was very poor (and worse than anticipated by apple). Visited a phones4u store - got fobbed off that "it takes a little while for the battery to optimize". So waited another four weeks - still the same thing. Contacted Phones4u and they said they couldn't replace as it was outside the 28 day rule!! Offered to send it away for repair - I declined, it was purchased and not fit for purpose from day 1. Huge mistake going to Phones4u - lesson learnt! Go direct to the provider next time and avoid the organ grinder at all costs!!
