With the iPhone 6s and 6s Plus, Apple didn't increase battery life over the iPhone 6 and 6 Plus, which means battery cases are going to remain a popular accessory for at least another year. In our latest video review, we went hands on with the ibattz Mojo Refuel Invictus battery case, which will fit the iPhone 6s Plus or the iPhone 6 Plus.
The ibattz is equipped with two removable and replaceable 3,000 mAh batteries, for a total capacity of 6,000 mAh. Each one of the batteries has enough juice to charge an iPhone 6 Plus or 6s Plus about 70 percent of the way, so combined, there's enough power to keep an iPhone going for a couple of days.
With two batteries in the Invictus Refuel case, it's quite heavy, but we didn't think the case itself was too bulky considering it's housing multiple batteries. There's a power button at the bottom of the case with LEDs for each battery, so you can get an idea of how much battery is left at a glance. The case itself recharges using micro-USB.
We liked the power this case provided, but we weren't a fan of the construction of the case itself. The materials felt a bit cheap and we were worried we'd break it putting it on the iPhone. The bulk of the phone also rendered the mute switch unusable due to a faulty mute switch on the case itself, so this is probably a case most users are going to want to pass on.
