Nexus 7 thinks its charging USB all the time

[SherbetDibDab]

To cut a long story short I love my nexus 7 but the charging has been terrible recently! It always thinks its being charged via USB when in reality I've tried lots of different AC chargers in various sockets around the house, what can I do???

Thanks everyone

What happens when you use the factory charger AND cable?
