Let's start this week with Apple, and specifically speculation coming out of Asia that they're in the process of testing a 13 inch iPad (with a screen size of around 12.5-inches) and that they may be looking to increase the screen size of future iPhones given that the iPhone 5 has a relatively modest (compared to ever-increasing screen sizes) 4-inch screen. There are also claims that Apple is about to start production on a new iPad with the same dimensions as the existing model but with an enhanced thinner and more lightweight display, which could be hitting the shops as early as the Autumn.

The other big rumour concerning Apple is that they are working on massively improving the battery life of their iPhones. It looks like they will be changing the way that the iPhone’s consume battery power with a new built-in system which will monitor and analyse how an individual uses their iPhone so the phone’s settings can be adjusted to maximise the life of the battery between charges. That'll certainly be handy but whether it's the 'wow' the public will be looking for from the iPhone 6 (the iPhone most likely to have this technology included) remains to be seen.

Talking of new smartphone launches, the Moto X, the brand new flagship phone from Motorola, is expected to make its debut next week. The Moto X will be the first smartphone to have been developed by Motorola and Google since Motorola was purchased by Google last year. As ever, there have been numerous ‘leaks’ in the press and online so we’re expecting it to feature a 4.5-inch screen, a 10-megapixel rear camera and a 1.7GHz dual-core processor. We’ll bring you more on the Moto X once it’s officially unveiled.

Now for some really good news - EE’s super-fast 4G network now covers almost 60% of the UK and is currently available in 95 towns/cities across the country. Launched around 9 months ago, the latest towns to be switched over include Tonbridge, Camberley, Crawley, Altrincham, Farnborough and Farnham. Three more cities have also been switched onto double speed, namely Newcastle, Belfast and Southampton which means they can benefit from 4G speeds of up to 60Mbps; this takes the number of cities enjoying double speed up to 15.

Things are just getting faster in the mobile world, they're getting bigger too.  Rumours are circulating that Nokia may be joining the realms of the 6-inch plus phablets according to an article in the FT and a recent leaked image on a technology site. It’s thought that Nokia are testing larger screen Lumias and aiming to produce a large smartphone which will compete with Samsung’s Galaxy Note. There are certainly system updates in the pipeline which would support a larger Windows phone and if the rumours prove to be true then the new handset could be ready by the end of 2013.

Those big screen devices need big batteries and frequent charging, so the eco-minded among you will be glad to hear that this week the University of Maryland in the USA is working on developing wooden batteries! Probably not the most obvious choice but apparently the ‘fibrous structures’ in wood could be charged to create an electrical current. It suggests the intriguing possibility of a mahogony phone with wooden batteries.  You may scoff but we've seen stranger things...
