Nokia reveals its first two Windows Phone 8 smartphones in this week's podcast, while Amazon announces a handful of new tablets.

And if that wasn't enough, there's an update from Everything Everywhere about its plans for 4G in the UK.

WDS, a UK-based Xerox group business that specialises in wireless customer experience, says smartphone makers are risking dissatisfied customers by not quoting battery performance in a way that reflects day-to-day use.

It analysed fifty of the top smartphones launched from August 2011 to August 2012, discovering that everyday features such as web browsing were generally omitted from battery specifications. Instead, there was a focus on standby time and talk time using 2G networks.

Nokia has announced its first two Windows Phone 8 devices at a special event in New York today.

The Nokia Lumia 920 is the company’s flagship Windows Phone 8 smartphone, incorporating the company’s PureView imaging technology with low-light capability and image stabilisation to offer clearer photographs. It’s also equipped with Nokia City Lens - a new location-based augmented reality service - along with wireless charging and a 2000mAh battery.

For many people, the biggest concerns about camping at a music festival involve inclement weather and sub-standard plumbing. However, the last few years have seen Orange reminding us about a third problem: mobile phone charging.

This year Vodafone has introduced its own take on festival gadgetry with the Booster Brolly. It’s a prototype umbrella created in partnership with University College London to keep festivalgoers dry (or protected from the sun) whilst charging their phones.

Free mobile apps can consume considerably more battery life than paid-for versions, according to new research produced at Indiana’s Purdue University in association with Microsoft.

Researchers found that battery life was adversely affected by advertising, which often helps fund free games but may use the phone’s network connection and GPS location software.
