HTC has announced an updated version of its One X Android smartphone.

The HTC One X+ has a similar design to its predecessor but offers improved performance, a longer battery life, more storage and the new HTC Sense 4+ user interface.

O2 UK says it’s going to sell mobile phones without chargers as part of a trial scheme with HTC. It’ll be offering a forthcoming HTC device with a USB connection cable but no mains charger. The phone uses the microUSB standard, which means it’ll charge via a PC and will work with many chargers for other devices.

Research from O2 suggests the UK has more than 100 million unused phone chargers.

We start this week's programme by talking about the iPhone 5 and iOS6 before moving on to HTC's forthcoming Windows Phone 8 devices.

There's also some mobile payment news, online shopping research, a health study, data about tablet manufacturing and machine-to-machine connection figures.

Oooh, a new phone. It’s running a powerful new processor, it has a large edge-to-edge toughened glass display and its model name bears the familiar ‘i’ suffix. Hang on a moment. Suffix?  Yes, suffix. This isn’t a new Apple device but Motorola Mobility’s first Intel-powered Android smartphone, the RAZR i.

HTC is the latest manufacturer to announce smartphones that use the forthcoming Windows Phone 8 operating system, following recent launches by Samsung and Nokia.

Described as ‘the first signature Windows Phones’, the Windows Phone 8X and 8S will be available from November with distribution already arranged in over 50 countries worldwide, including the UK.
