Apple’s bigger iPhone 6 is a great product, but its battery could still do with some work. Fortunately, there’s a solution coming, but you’ll have to sacrifice some of the thickness to make it work.

If you’re an iPhone 6 owner and you haven’t been too impressed by the battery — but love everything else about your new phone — Mophie has a fix coming.

Launched at CES this week, the product that put Mophie on the map is being made for the iPhone 6 and iPhone 6 Plus, with the Juice Pack on the way for the 4.7 inch iPhone 6 in the Juice Pack Air and Juice Pack Plus, while the larger 5.5 inch iPhone 6 Plus will receive the Juice Pack.

“Our journey to bring the juice pack to consumers for every generation of iPhone continues with our latest solutions for iPhone 6 and iPhone 6 Plus,” said Daniel Huang, CEO and Co-Founder of Mophie.

“Since the release of the original juice pack for the first iPhone, Mophie battery cases have become a necessity to legions of smartphone users. Because we understand how vital these solutions are, our team remains intensely focused on quality and the level of innovative design needed to drive the direction of this industry.”

Each version of the Juice Pack will deliver slightly different battery boosts, with the iPhone 6’s options being useful for 100% more battery in the Air, 120% more in the Plus, and 60% more battery on the iPhone 6 Plus side of things.

The batteries act as cases for the phones, too, with rubberised edges to help stop the phones from breaking after a fall, while Mophie’s “Impact Isolation System” apparently improves things further, found only on the Juice Pack Plus for the iPhone 6.

Mophie’s battery cases also bring a microUSB port to the table, meaning you can charge the cases using the same connection so many phones and tablets are already using, while the cases include buttons that connect straight through to the volume, mute, and power buttons, making these usable through the case.

Pricing in Australia for these products hasn’t yet been announced, but we suspect you’ll see them from a $120 starting price, with availability possible (and likely) later in the year.
