Over on Guy Goma Kewney site, James Sherwood has pictures of a lovely mobile phone battery solution from MWC - the Philips 9@9j mobile phone takes not only a custom Lithium Ion battery, but also has a slot to take a regular AAA battery to top up the main battery for another three hours of talk time. If I was travelling, and I had the option to strap in a standard cell to my Symbian phone, I would be right there.

Dubbed with the curious name of 9@9j, the candybar handset has a standard lithium-ion battery inside and, should it run out of life, then the AAA battery, which slides into a slot at the bottom of the phone, kicks in to give the handset’s lithium-ion battery a little more juice.
