Sony Xperia Z Ultra phablet owners can now enjoy an extended battery life thanks to a new Mugen Power case for the device.

Samsung has started a real trend with its Galaxy Note, charting the territory for large-screen devices with smartphone functionality. If at first industry observers were skeptical on whether consumers would buy a huge smartphone, the phablet trend has really taken off and more companies started to launch their own super-sized smartphones. There is no doubt today that high-end phablets are successful and they are becoming increasingly popular each day.

On the phablet front, Sony has its large-screen Xperia Z Ultra, which boasts a massive 6.4-inch display. However, large displays, high resolutions, powerful processors, and high-end features take a toll on battery life. The new Mugen Power case for the Sony Xperia Z Ultra aims to prolong the battery life of the device so users can enjoy it for longer.

The Sony Xperia Z Ultra comes with a 3,050 battery, just like the new-generation Samsung Galaxy Note 3. While for many users that battery might suffice, heavy users may need a little more juice - enter battery cases.

For those power-hungry users, Mugen now has a 4,000 mAh Extended Battery Case for the Sony Xperia Z Ultra. The new CC-6802 Mugen Power Extended Battery Case accessory is immediately available for order and costs $98.50. Shipping, however, won't start until Jan. 17.

As expected, the case will provide Sony Xperia Z Ultra owners with an additional 4,000 mAh battery to extend the non-removable 3,050 unit the device packs. The bottom of the case has a switch, allowing users to easily toggle between the battery pack and the phablet's own battery.

Moreover, a kickstand will allow users to view video content in a more convenient manner, and the case also includes its own stylus.
