Apple Smart Battery Case

  • Capacity: 2,365mAh
  • Output: 1A
  • Size: 7.4 x 3.5 x 0.9 inches
  • Weight: 158.7g (5.6 oz)

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 cutout 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.

You can also use the case with Lightning-supported accessories, including the Lighting to USB cable and the charging dock, without having to remove it. 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 Wireless

  • Capacity: 2,525mAh
  • Output: 1A
  • Size: 5.90 x 2.80 x 0.65 inches
  • Weight: 99.5g (3.51 oz)

Mophie’s Juice Pack Wireless battery case should more than double your iPhone 7’s battery life, and it also adds support for Qi wireless charging. The case will last for 500 recharges and can provide an estimated 27 hours of extra battery life to your iPhone 7. Just press and hold the button on the back for 2 seconds to begin charging your phone. The Juice Pack Wireless has LEDs on the back to show how much power is left. It also supports pass-through charging, so when you plug in, it will charge your iPhone 7 up first.

It adds quite a bit of bulk, but it doesn’t block the speaker, microphone, camera, or any other important components of the phone. The case is actually 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.

Trianium Atomic Pro Battery Case

The best iPhone 7 battery cases
  • Capacity: 3,200mAh
  • Output: 1A
  • 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-plus 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 most other battery cases for the iPhone 7, 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 has a hard back plate and a protective dual-layer bumper that safeguards against drops, shocks, and scratches. While it adds a bit of bulk, it does offer good protection.

Alpatronix BX170 Charging Case

The best iPhone 7 battery cases
  • Capacity: 3,200mAh
  • Output: 1A
  • Size: 6.05 x 2.87 x 0.63 inches
  • Weight: 107.7g (3.8 oz)

This case from Alphatronix 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 headphones Apple provides. The case also 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 drawbacks, this is a great iPhone 7 battery case, as well as 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 the phone is facedown. All ports are accessible, there are LED indicators on the back, and it’s covered by a lifetime warranty.

Moshi IonSuit iPhone 7 Battery Case

The best iPhone 7 battery cases
  • Capacity: 3,020 mAh
  • Output: 2.1A
  • Size: 6.1 x 2.8 x 0.7 inches
  • Weight: 113g (4 oz)

If you’re looking for a great battery case that’s also super protective, the Moshi IonSuit iPhone 7 Battery Case is worth considering. The case is a little bigger than some of the others on the list, but the result is that the case is drop-rated, and it has a lip around the screen to prevent the screen from any contact should the phone be dropped.

The actual battery in the case comes in at 3,020mAh, which effectively doubles the battery life of your phone, plus it supports 2.1A quick-charging, meaning it’ll charge a little quicker than some of the others on this list. The case is a little expensive, but for many it will be well worth spending that cash.
