The Best iPhone 6 Battery Case

Trianium Atomic S iPhone 6/6S Charging Case

The iPhone 6 Battery Case (Cellphone case with Battery Charger included) is a must have if you use your iPhone 6 on a regular basis. And, getting a battery case is a no-brainer especially if you are a power user – which most of us are.

One of the great things about the iPhone 6 is that it is bigger, better and most importantly, more beautiful than any other previous iPhones. It also offers an unparalled performance compared to its rivals. However, this comes at a cost – the battery life.

Therefore, you want a case that is not only going to protect your phone but also let its beauty shine through and keep it charged up and going for hours.

Our pick for the best overall iPhone 6 Battery Case is : Trianium Atomic S iPhone 6 Battery Case

Trianium’s  Atomic S iPhone 6 Battery Case is a powerful 3100mAh Li-polymer rechargeable battery that can effectively provide 100%+ extra battery life for your iPhone 6. In other words, it is perfectly capable of providing a full charge to iPhone 6.

It’s beautiful, incredibly thin, and has a cleverly designed two-part bumper that protects the phone very well. The rubbery matte finish is grippy and feels great in your hands.

You can simultaneously charge your iPhone and battery case together with the included microUSB cable. The case provides USB pass-through so you can sync your phone while the phone is still in the case. The case deploys microUSB input to lightning 8-pin output – so you don’t have to spend money on multiple apple cables.

The camera/flash area is given plenty of clearance so you can get worry-free flash pictures. The LED battery level indicator in the back lets you know exactly how much power you have.

It works with iOS 8+ and comes with a Lifetime Warranty from Trianium – for your complete peace of mind.

For all that it has to offer, The Trianium is not only an excellent protective case, but it’s also well engineered, thin, and holds a large amount of juice for the power hungry iPhone 6.

There are not too many battery cases for the iPhone 6 yet. Of the ones that are out there, Trianium’s  Atomic S is the winner.

Other iPhone 6 Battery Cases That Are Also Great

Here are a few other iPhone 6 Battery cases that are worth considering:

Anker Ultra Slim Extended Battery Case for iPhone 6

Anker Ultra Slim

If you use your phone a lot,  Anker’s Ultra Slim is the battery case you’ve been looking for.

It will provide you a full charge, and a half, (around 140%+), giving you more than enough power to work and play on it all day long. 2850mAh capacity provides an extra 70 hours audio playback, 19 hours  talktime, 15 hours video, 14 hours web browsing or 3½ hours 3D gaming to your iPhone 6.

You’ll love the slim look and matte finish which is print-resistant. It feels great on your hands.

It’s one of the fastest charging battery cases I have come across. If you see your battery running low, simply press the button on the lower back of the case and your phone will automagically start sucking in the battery juice.

Anker’s Ultra Slim Battery Case comes with a Micro USB cable, audio jack extender, welcome guide and 18-month warranty.

i-Blason iPhone 6 External Protective Battery Case


i-Blason’s battery case has  simple and polished design, and the whole back of the case feels very smooth in the hand. However, that also means the case is not very grip friendly and can more easily slide out of your hand than others.

The 3200mAh built-in smart lion-thium polymer battery provides 100%+ charge for your iPhone 6 battery.

It’s precise cut and design give you easy access to all ports, sensors, speakers, cameras and all iPhone features.

However, keep in mind that the case makes the phone longer and slightly thicker.  It still fits comfortably in your pocket, but you’ll definitely  feel its length and heft.

Because i-Blason adds to the length of the phone, you need to use a headphone jack extension, which is included. But if your headphones have a thin and long headphone plug, this might not be a huge issue.

Powercase iPhone 6 Battery Case


While Powercase is not the best iPhone 6 battery case out there, if you are on a budget, this will get the job done.

You will not find a better battery case for under $13 bucks. There is a reason why this has been on top of the Amazon’s bestseller list for battery cases.

It will fit your iPhone 6 well, and will charge the phone just as intended. You need to push the charge button, whenever you want to boost your phone battery.

The case has a wonderful texture and a very clever design. You’ll like the matte black finish  and the nice satin feel in the hands. The kickstand is great for watching movies/TV shows.

You won’t, however, be able to recharge the case and the phone at the same time.

Buy the Powercase for what it is, without too much expectations, and you will be pleasantly surprised.

Stalion Stamina iPhone 6 Extended Charging Case

Stalion Stamina

Smooth finish, 3100mAh battery and 2  changeable frame make Stalion Stamina another great buy when you are looking for battery case that will fully charge your phone and looks stylish.

It has four LED light indicators on the back to show how much power your case has. You use the power button on the back of the case to power on your battery case. The case has a built in smart sensor to prevent overcharging and overheating.

In order to turn the battery case ON or OFF, the “Power” button must be pressed for 2 seconds and then released. This prevents unintended battery power-on (for example – when in a pocket or purse).

This slim and light case charges very fast and you will also be able the recharge the phone and the case at the same time.

ZVOLTZ ZT6 iPhone 6 Battery Case


ZVOLTZ ZT6 comes with a fully protective hardshell case with a removable bumper. The removable bumper reduces added bulk while offering comprehensive protection for your phone.

Like others, it has LED battery level indicator, charge & sync through the case, and conveniently placed cutouts for all buttons and ports.  The battery capacity is rated at 3100mAh – which will charge your iPhone 6 roughly about 1.5 times.

It also comes with a headphone extension cable, just in case. The cutouts are just right for your buttons and speakers – so  the sound is not muffled.

It’s a bit on the heavier side of the other battery cases we reviewed.

You get 1 year warranty by  ZVOLTZ and guaranteed compatibility against future iOS updates.
