I've reviewed nearly a dozen iPhone 6 battery cases since the launch of
This is great news as it also more than doubles the effective battery life and increased the time between charges - welcome in anyone's books. However, they're mostly quite bulky and once their internal batteries are depleted, you'll be reaching for a wall socket again. Thankfully, iBattz has an answer to both of those questions with its new Mojo Refuel Invictus battery charging case.

iPhone 6 Battery Case Roundup: 5 Ways To Double Battery Life
Boost Your iPhone 6's Battery Life With The Lenmar Battery Case
The most exciting feature is that it uses removable batteries and these are readily available as they're actually the N9005 model that's used by Samsung's Galaxy Note III. As you can easily remove it - even while the iPhone 6 is installed, this means you can carry several with you, changing them when needed. This gives you essentially unlimited battery life - the batteries are the same size as a credit card and only a few millimeters thick so carrying half a dozen with you is no hardship at all.
In fact, you could quite easily carry dozens and have enough power on hand to keep your iPhone running for a month or more. That's a pretty extreme example, but I've seen plenty of non-Apple handset owners carrying around spare batteries for their handsets - of course many other handsets sport user-removeable batteries and while its possible to remove the iPhone 6's battery, it's not something you can do quickly or easily - at least not for battery life purposes.
The battery's capacity is 3,200mAh, equating to around 120% of the standard iPhone battery, so you can recharge a flat iPhone 6 to full, with a good 10-20% left over for another blip. A separate product is available that comes equipped with another battery and a USB-powered charger so you can top up your depleted batteries once your iPhone 6 has sucked them dry.
The case itself is quite possibly my favourite iPhone 6 charging case yet. It's a few millimetres thinner than all other cases I've tested and it's noticeable too. It's also a few grams lighter. This is mostly due to the fact that the proective lip that usually protects the screen all the way round, allowing the case to take the hit in case of a drop, isn't actually present all the way round.
Instead, two protrusions at the top will prevent the iPhone's screen taking the brunt of any face-down impacts. Despite its smaller size, the case sports the same battery capacity as other I've looked at and also has an enlarged headphone jack, which should allow nearly all 3.5mm minijacks to fit in without needing to use the included adaptor.
To charge the case you use a standard micro-USB cable and one is included in the box. A full charge can take a couple of hours, even from the mains and as usual, the case will allow the iPhone to be charged first before tapping into the full power to boost its own battery.
You can of course force the battery to be charged using the button on the base and this is also how you activate and deactivate charging on the move - it's a pretty simple device. To open up the case, you simply pull off the back cover, which reveals the battery. You can then remove the top section and insert your iPhone 6.
It's certainly not as easy to work with as most other charging cases I've used, but then most of those are larger, heavier and don't sport a removable battery. The case has a cut-out for the vibration/ring button, but overlaid buttons for the volume and power buttons.
The latter aren't as nice to use as the real things - you do get used to them, but I'd have preferred to see cut-outs for these buttons instead. Finally, there's an LED on the rear of the Mojo Refuel Invictus, which indicates whether or not the case is charging and also what the battery charge level is.
Overall, despite one or two niggles, the Mojo Refuel Invictus is my new favourite battery charging case for the iPhone 6. It's the thinnest and lightest I've used so far and the ability to quickly replace its battery with another is a huge boon that I can see many people taking advantage of.
As the batteries themselves cost less than $10 on Amazon, owning a handful isn't going to cost a fortune, but could see you gain days of batterylife without the need to carry around a heavy portable battery.
