The battery of the case is 3,000mAh which is similar to the Sony Xperia Z Ultra’s battery, meaning that it will be good for one full recharge, nothing more, nothing less, and thanks to its magnetic connector, you will be able to charge the case and the phone at the same time, so you don’t have to go through the hassle of removing the case and charging both devices separately. In fact the Power Cover CP 12 will even sport a stylus which you can use to navigate around the handset, although we’re not sure if it will come with the same level of stylus support you might find with the Galaxy Note 3. Unfortunately pricing or availability remains unknown, but if you’re looking for a multipurpose accessory for the Sony Xperia Z Ultra, this might be it.
