The Philips Xenium NRG — apparently Zorbiantium SPRFLY was already taken — is the first “commercial” mobile phone to use Techitium’s BackuPower system which allows phone users to add a little AAA battery to a phone to get a bit more juice without charging.

The old fella at their booth wouldn’t let me take pictures, but it basically looks like a white Walkman phone with a little bump where you hide the battery — definitely nothing to write home about and there was no mention of actual availability.

The concept, however, is quite cool and would make for a great entry-level phone, especially in developing countries where power — and power jacks — might be few and far between. Will we ever see it and/or ever care? Probably not, but it’s nice to know it’s out there.
