7 Battery Cases for iPhone 6 and 6 Plus

There are two things your smartphone can never have enough of: storage for your music, apps, and photos, and battery life. The iPhone 6 and iPhone 6 Plus sport powerful, long-lasting batteries, but even the best batteries can be drained by intensive use. When your battery is low, you don't have to worry about plugging your phone in if you've got an extended life battery case.

These accessories are iPhone cases with batteries built into them which can provide extra juice to your iPhone—along with protection from drops and, in some cases, extra features like waterproofing or enhanced audio capabilities. Check out these 9 battery cases for the iPhone 6 and iPhone 6 Plus.

Ascent Solar EnerPlex

The first case on this list is unique: an iPhone battery case that can recharge itself not just by plugging in but also by using solar energy. The back of the case features solar panels to suck in energy from the sun to store in the case's 2700 milliampere-hour (mAh) battery.

Ascent Solar claims that the case can deliver about 10 hours of additional use to the iPhone that it's connected to

Incipio's affordable, $80 offGRID Express functions in the same way that all of the cases on this list do: they have batteries in the case that you charge separately via a microUSB port and then, when the iPhone needs to be recharged, you turn on the battery and send the power from it to the phone.

The offGRID Express sports a 3000 mAh battery, which should provide more than 100% additional battery life, according to Incipio.

As with a number of other cases on this list, the offGRID Express adds some width to the bottom of the phone, making the headphone jack difficult to reach. An included headphone jack adapter solves this problem.

The Mojo Refuel Invictus brings a neat twist to iPhone 6 series battery cases: a replaceable battery.

With the other cases on this list, when the battery starts to lose the ability to hold a full charge (as all batteries eventually do), you have to get rid of the whole case. With the Mojo Refuel Invictus, though, you hold onto the case and just swap in a new 3200 mAh battery. 

The case provides around 100% additional battery life and comes with a headphone jack adapter. It weighs 4.23 ounces.

Mophie is one of the biggest and longest-established names in the extended battery case market. It offers a number of models, including the thin and light juice pack air and the higher-capacity juice pack plus.

Both come in black, white, or gold, with the air offering a 2750 mAh battery for about double the battery life and the plus packing a 3300 mAh battery, which will more than double your iPhone's battery.

The air weighs in at just 3.5 ounces, while the plus tilts the scales at 3.9 ounces.

Otterbox makes some of the most popular, and rugged, iPhone cases on the market. With the Resurgence, it brings it expertise in making great products to battery cases.

The Resurgence offers a 2600 mAh battery, which should provide around 100% more battery life to your phone, according to the company. Also included with the case is a headphone jack adapter.

If you want to more than double your iPhone's battery life, check out Tylt's Energi case. The iPhone 6 model sports a 3200 mAh battery, while the version designed for the 6 Plus offers 3500 mAh.

Like other cases on the list, it adds bulk to the outer edges of the phone, making it hard to access the headphone jack; an adapter is available from Tylt. That bulk can also make it difficult to access other buttons, such as the mute/ringer switch, so you may want to try one in person before buying.

HiFi Skyn iPhone 6 battery case

This case will appeal most to audiophiles who want to have the ideal music experience with their smartphone. Some really high-end headphones require an amplifier to work; the iPhone, which puts a premium on being thin and light, doesn't offer one. CEntrance's HiFi-Skyn looks to solve that.

This case has an amp built into it as well as an extra battery designed to provide up to 10 hours' additional life for your iPhone. The Skyn is being released via crowd-funding site Indiegogo and should ship in March.
