Best iPhone 7 battery cases to keep your phone above 20 percent

by John_A

Depending on how much you use your iPhone 7, a full charge is either enough to get you through the day, or not nearly enough to keep up with you. Sometimes you simply need some music, but when you’ve got Bluetooth turned on, music streaming, and cellular data running, your battery isn’t likely to last long. This is where battery cases come in handy.

There’s a general lack of battery cases out there for the iPhone 7 that take advantage of its capabilities, and there are even fewer that won’t interfere with the lightning port, which now doubles as the headphone port. However, there are enough available to give you exactly what you need from a battery case. Check them out below.

Apple Smart Battery Case ($85+)


  • Capacity – 2,365mAh
  • Output – N/A
  • Size – 5.45 x 2.64 x 0.28 inches
  • Weight – N/A

Apple’s own Smart Battery Case is the go-to accessory if you want seamless integration with your iPhone 7. If you have any experience with the iPhone 6S’ Smart Battery Case, you’re in for much of the same with the one made for the iPhone 7, save for a different cut-out around the camera and none for the headphone jack (because the iPhone 7 doesn’t have one). The case will increase your call, internet, and video time by 26, 22, and 24 hours, respectively, meaning even heavy smartphone users should be able to use their devices without worrying about a full recharge.

Moreover, you can use the case with Lightning-supported accessories without removing it, including the Lighting to USB cable and the charging dock. As far as protection goes, this case is pretty basic. The interior is lined with a microfiber material, while the outside is made of silicone.

Mophie Juice Pack Air ($100)

mophie juice pack air for iPhone 7 and 7 Plus

  • Capacity – 2,525mAh
  • Output – N/A
  • Size – 5.90 x 2.80 x 0.65 inches
  • Weight – 99.5g (3.51 oz)

Mophie’s Juice Pack Air battery case is very similar to the battery cases the company has made for the iPhone 6 and iPhone 6S. The case will last for 500 recharges, and during use, can provide an estimated 27 hours of battery life to your iPhone 7 and iPhone 7 Plus. Just press and hold the button on the back for two seconds to begin charging your phone. The Juice Pack Air has LEDs on the back to show how much power is left, can be charged without removing the iPhone, and doesn’t block the speaker, microphone, camera, or any other important components of the phone. In fact, the case is designed to enhance the speaker’s audio quality, as it redirects sound from the bottom of the phone to the front. It’s also compatible with Mophie’s Charge Force wireless mount, so you can easily charge it while driving.

Foxin Battery Case ($20)


  • Capacity – 6,800mAh
  • Output – 1.0A
  • Size – 7.2 x 4 x 1.1 inches
  • Weight – 181g (6.4 oz)

If you power through your iPhone 7’s battery multiple times a day, Foxin’s battery case will be able to support you, as it’s capable of fully charging your phone two times a day, thanks to its own 6,800mAh battery. To complement that, you can charge your phone while it’s in the case, and once the iPhone battery is full, the charge will continue on to the battery case itself. There’s also a USB port on the side, allowing you to charge another device.

There is a flaw with this particular case, however, and it lies with the iPhone 7’s own Lightning port. Even though the port can be used to attach the phone to the case and to charge it, you’re unable to use the Apple earpods that come packed in with every iPhone. If that’s not a huge deal breaker, you can buy this case with confidence. Smartphone protection is standard with this case, so expect some defense against falls and shocks, but avoid bigger drops if you can.

Maxdara Charging Case ($16)


  • Capacity: 5,200mAh
  • Output: 1.5A
  • Size – 5.6 x 2.7 x 0.6 inches
  • Weight – 82.2g (2.9 oz)

Maxdara’s battery case will keep your iPhone 7 charged and ready, and it’ll let you know just how much power your case has left, thanks to the battery indicator located on the back — White: 100 percent, Green: 75 percent, Blue: 50 percent, Red: 25 percent. When the time comes to charge your phone using the case, you use the On/Off switch (also located on the back) to start and stop the process. The case has precise cutouts for your phone’s microphone, buttons, and camera. It’ll also protect your phone from scratches and shocks. It’s made with a dull polished material that results in a comfortable case you can hold for all the hours you’ll be using your phone.

Trianium Atomic Pro Battery Case ($40+)


  • Capacity – 3,200mAh
  • Output – N/A
  • Size – 5.9 x 2.7 x 0.4 inches
  • Weight – 158.7g (5.6 oz)

While Trianium’s battery case has one of the lower capacities on this list, it’ll still get the job done when it comes to keeping your phone alive. It can provide another full battery charge, or, as Trianium breaks it down: 14+ hours of talk time or 10 additional hours to browse the internet. The LED indicator on the back will keep you up to date on how much power remains.

Unfortunately, like other battery cases for the iPhone 7 so far, it doesn’t support Apple’s lightning headphones, or other headphones that use the lightning port. If you’re concerned about overall protection, the case ensures your phone’s safety by utilizing a hard back plate and a protective dual-layer bumper, resulting in protection against drops, shocks, and scratches. While it adds a bit of bulk, it does offer good protection.

Alpatronix BX170 Charging Case ($30+)

iPhone 7 battery case from Alphatronix

  • Capacity – 3,200mAh
  • Output – 1A
  • Size – 6.05 x 2.87 x 0.63 inches
  • Weight – 107.7g (3.8 oz)

Alphatronix’s case will get the job done when the time comes to recharge your phone, but like some other charging cases, it is not compatible with the packed in headphones Apple provides. Furthermore, the case isn’t charged using the Lightning connector, but instead requires a Micro USB cable — thankfully, there is one included. You can still charge the case without removing the phone, but it means keeping another cable nearby.

Aside from those minor setbacks, this is a great iPhone 7 battery case, and a decent protective case. The dual layer design combines a hard outer shell with a shock absorbing bumper, there’s a scratch-resistant finish, and the raised bezel will keep the screen away from surfaces when face down. All ports are accessible, there are LED indicators on the back, and it’s covered by a 1-year warranty when bought directly from Alphatronix.

Anker PowerCore Battery Case ($50)

  • Capacity – 2,200 mAh
  • Output – N/A
  • Size – 5.55 x 2.76 x 0.6 inches
  • Weight – 68.03g (2.4 oz)

While the Anker PowerCore is made to work with the iPhone 7, it will also easily work with the iPhone 6 and 6S given the phones have similar exterior designs. The PowerCore employs the iPhone’s lightning port to charge your phone, and can give it an almost 100-percent charge, providing between 11 and 13 hours of extra battery life. To charge the battery case for future use, you need to use the included Micro USB cable with the case’s Micro USB port. When not in use, the PowerCore doesn’t need to be constantly connected via the Lightning port — meaning you’re free to use your headphones — and can instead act as a protective case that will help keep your phone secure. That said, since it’s not a dedicated iPhone case, or one that’s meant to prevent dents and scratches, Anker recommends not dropping it.

ThinCase ($60)

  • Capacity – 3,000 mAh
  • Output – N/A
  • Size – N/A
  • Weight – N/A

We’ve written about the ThinCase before, and now that it’s just on the horizon, we’re going to talk about it again. This is an impressive battery case, not just because of how well it charges your iPhone 7, but because it manages to bring back the headphone jack the current iPhone model left behind. The ThinCase also offers pretty decent protection, thanks to raised edges that keep the display away from surfaces when placed face down, as well as a durable design that prevents bumps, dents, and scratching. A kickstand feature is also built directly into the case, and can be used simply by opening the front cover and flipping it over.

The ThinCase doubles your iPhone battery life, providing an additional 14 hours of use, and doesn’t need to be removed in order to be charged again. In fact, both the case and the phone can be charged simultaneously due to its pass-through charging feature. According to its creators, you can charge the ThinCase in less than two hours, though charging the case and phone together will take about 3.5 hours. Few other iPhone 7 battery cases match the feature set the ThinCase provides, so it may prove hard to pass up.

ZeroLemon Battery Case ($35)

  • Capacity – 3,100 mAh
  • Output – 1.0A
  • Size – 6 x 2.87 x 0.63 inches
  • Weight – 108g (3.8 oz)

ZeroLemon’s battery case isn’t drastically different from other offerings on our list, but it’s another quality option if you’re searching for a way to keep your phone charged up and somewhat protected. You get about 12 hours of additional battery life using this particular case, and the four LEDs on the back will keep you updated regarding the case’s battery levels and charging status. Both the case and iPhone can also be charged at the same time using the included Micro USB cable, and your phone can be connected to your PC without removing it from the case.

As a protective case, it’s on the slimmer side, adds minimal bulk to the iPhone, and is sure to defend against everyday scratches and bumps. As for drop damage, it can handle a small drop from your coffee table, but maybe not a drop from the roof of your car. Also, keep in mind that you can’t use your wired headphones with this — just Bluetooth-equipped models.

PhoneSuit Elite 7 Pro Battery Case ($80+)

  • Capacity – 3,000 mAh
  • Output – 1.5A
  • Size – 6.02 x 2.79 x 0.55 in
  • Weight – 90g (3.17 oz)

The PhoneSuit battery case is definitely one of the more expensive cases on our list, alongside the offerings from Apple and Mophie, but you can see where the money went. At first glance, it looks a lot like other battery cases we’ve written about, but there are some small differences in how you interact with the case — namely how you activate the case to charge your phone. Typically, you press a button, but the PhoneSuit incorporates touch controls for a more modern feel. Touch the left side for a second to check battery status, or both the left and right sides for three seconds to start or stop charging.

The PhoneSuit also supports pass-through charging, PC sync, and will automatically turn off when it has charged your phone. It uses polycarbonate composite materials and a scratch-resistant coating, helping to keep your iPhone in perfect condition when out and about. The exterior design uses a rubber, soft-touch coating to provide additional grip, and though it’s expensive, it has everything you’re looking for in a quality battery case.
