Price comparison company uSwitch.com finds that 71 per cent of UK smartphone users have experienced issues with their handsets. 48 per cent cite short battery life, 31 per cent have internet/3G failure, 23 per cent experience frozen screens, and 14 per cent encounter software faults.
Battery life and poor 3G coverage are the biggest gripes for users, but there's also problems with basic commands as 12 and seven per cent have issues sending and receiving texts, while 13 per cent find calls cutting out.
Ernest Doku, telecoms expert at uSwitch.com, said: "As phones have got smarter, they have also got more temperamental. And, while manufacturers continue to push the boundaries with new designs, consumers shelling out for top of the range devices will be frustrated that they aren’t getting the most out of them."
