Best battery cases for iPhone 7 and 7 Plus


The iPhone 7 may be almost four years old, but as one of the last smartphones Apple made with Touch ID, it’s still wildly popular.

It’s held up particularly well with the latest version of iOS and the still excellent A10 Fusion processor.

One of the areas where you might feel some strain is in battery life. The iPhone 7 only had a 1,960mAh battery, while the 7 Plus did slightly better at 2,900mAh.

While it might have been ok to last a full day when you first bought it, you might struggle to get more than a few hours out of it now. This is where a battery case comes into play.

One of the iPhone 7 battery cases tested here claims to be compatible with the iPhones 6, 6s, and 7 due to its larger rear camera cutout, but most 6/6s cases fail the camera cutout test.

Many of the products recommended here are compatible with the newer iPhone 8, but you can also check out a separate guide on the best battery case for iPhone 8 and iPhone 8 Plus.

Apple iPhone 7 smart battery case

Apple’s smart battery cases may not live up to the company’s usual sleek design language, but they’re very practical.

The case has a soft elastomeric hinge that makes it super easy to slide the iPhone in and out of the convenient one-piece design. Many battery cases come in two pieces that can sometimes come loose and become lost or broken.

You can sync and charge iPhone 7 and Battery Case at the same time when the phone is in the case. This uses the same Lightning cable that you get with the iPhone.

Unusually, the iPhone 7 first draws power from this case before using its own internal power. With most other battery cases, the phone first drains its own battery and then uses the case’s extra battery. The case ensures that the iPhone is 100 percent charged for as long as possible.

There is no LED battery level indicator on the outside of the case, although curiously there is one inside. Instead, the battery status is displayed on the iPhone lock screen and in the notification center. This seemed strange at first, but you quickly get used to it and it’s actually a nice idea.

The iPhone 7 Smart Battery Case has a charging capacity of 2,365 mAh, which is lower than most battery cases, but enough for a full charge, but not more until it is recharged itself.

At £99/$99/AU$149, the Apple iPhone 7 Smart Battery Case doesn’t come cheap, but if it both protects your valuable phone and gives you enough power to get you through the day, then it represents good value for money , and since it is made by Apple, you can be sure of its build quality and security.

Mophie Juice Pack Air for iPhone 7

Mophie Juice Pack Air

Mophie is the market leader in smartphone battery cases and it’s great that there’s now a dedicated case for the Apple iPhone 7 and iPhone 7 Plus – as well as its Magnetic Hold Force solution (see later in this feature).

The Mophie Juice Pack Air for iPhone 7 is compatible with Qi and other popular wireless charging systems, which sets it apart from other battery cases reviewed here. Charge Force technology magnetically adapts to all Mophie Charge Force wireless accessories (e.g. the £39.95/$39.95 charging dock). Simply place your Mophie case on any wireless charging dock and your device will be powered upon contact.

The wireless charging option is great if you buy one of the optional Mophie charging stations. It simplifies your everyday life by saving you the hassle of finding the right cable and plugging it in the right way.

Either wireless or wired, the phone charges first, followed by the Juice Pack battery. The iPhone 7 model has a battery capacity of 2,525 mAh and the iPhone 7 Plus version has 2,420 mAh – both enough for a full charge when the battery is low.

A battery compartment isn’t just for charging. It’s just as important that it protects your phone – after all, a fully charged but broken or damaged phone is about as useful as a dead one. The iPhone 7 Mophie Juice Pack Air features rubberized support pads and raised corners to protect the screen from drops and scratches.

The Mophie Juice Pack Air for iPhone 7 looks and feels good. The buttons are nice and responsive.

It adds more bulk to the iPhone than some of the slimmer cases reviewed here. One disappointment is that this case charges via a micro-USB connector rather than Apple’s Lightning connector – meaning you’ll have to endure the usual non-reversible micro-USB fumbling and need an extra cable lying around when you need it (unless you opt for the wireless charging option). It’s also a two-piece case design, which doesn’t pose much of a difficulty, but one-piece designs seem to be more popular these days.

Each is available in black, gold, rose gold, navy, and red. You can buy it now for just £59.95 / US$59.95 for the iPhone 7 and 7 Plus.

Fuze case

The Fuze Case is a battery case for the iPhone 7 and 7 Plus that promises not only extra juice when you need it and rugged protection, but also the return of the 3.5mm headphone jack.

Apple removed the headphone jack from the iPhone 7 and expects users to switch to Bluetooth headphones or use the included dongle adapter that fits into the 7’s Lightning connector.

While Apple allows more design freedom, it means iPhone 7 users will have to buy expensive Bluetooth headphones. And with the adapter installed, you can no longer listen to music and charge or sync your phone at the same time.

Fuze corrects this by adding a headphone jack to the case.

The battery capacity of the iPhone 7 Case is 2,400 mAh, with 3,600 mAh for the iPhone 7 Plus Fuze Case. In our testing, we barely achieved a full charge when switching to the case as the iPhone 7 dropped to 10% battery charge.

The case is super slim and at 68g (excluding the phone) it is significantly lighter than the Apple Smart Case at 101g.

Only the black case is currently available, but the blue, white, gold, and pink cases will be available in March 2017.

At the moment Fuze is awaiting MFI accreditation from Apple and as such not all promised features work. Until that’s sorted out, your headphone mic and inline controls won’t work, and the Lightning connector only allows for charging. Syncing and audio streaming are not working. Additionally, an error message may appear. The promised headphone integration doesn’t work either, so while this is a nice slim battery case we don’t think it does much more despite the claims!

There is an offer where the Fuze Case is only $49 instead of that US$90 MSRP, but from a recommendation perspective, we’d wait until Apple approves the Fuze case and updates the case to make it work properly before purchasing. International shipping outside of the US is $15. Buy direct from Fuze.

Ekrist Battery Case for iPhone 8/7/6/6s

A 6000mAh capacity means both the regular and Plus models can be charged at least twice, while LED indicators give a quick overview of how much juice is left.

As with many battery cases, when plugged into AC power, your iPhone will first charge before the case is juiced.

It also features 360-degree scratch protection, so it can withstand everyday wear and tear.

The standard 4.7-inch compatibility means it will also fit the iPhone 8, 6 and 6s, but not any of the Plus models.

You can buy it now for £25.90, although it doesn’t currently ship to the US.

Fey-EU Slim Battery Case for iPhone 6/6S/7/8

With so many third-party iPhone battery cases featuring a generic black design, Fey-EU’s option really stands out from the crowd.

The eye-catching red trim really adds to the design of your iPhone 7, although again it also supports the 8, 6 and 6s models.

Its main selling point over other battery cases is durability. The hard shell design offers military-grade protection, while a soft bumper inside supports your phone’s most sensitive areas.

A capacity of 3100mAh is enough for the iPhone 7 to be fully charged and have plenty of space, although it doesn’t support the 7 Plus.

You can buy it now for £29.89/US$39.89

iPhone 7 Battery Case Buying Guide

There are a few things to consider when buying an iPhone 7 battery case. Here are four key areas to keep an eye on.


It’s not quite as easy as it sounds, but make sure you have a large battery capacity in the case. It has to be at least 2,000mAh (milliamp-hours), but that would only scrape a full charge and probably only give you 80 per cent more juice – enough, but there are better ones out there. Read dedicated articles on phone battery charging tips and iPhone battery life extending tips.


An equally important role of the battery case is to protect your phone from bumps, falls, falls and bumps. We consider the robustness of the case in all of our tests. Also note that while the iPhone 7 is waterproof, most cases are not.

(Also see our roundup of the best iPhone 7 and 7 Plus cases).


Look for light and slim battery cases if you appreciate the iPhone’s raw stats. Usually you sacrifice some slimness for extra battery capacity.

charging cable

Try to choose a battery case that uses Apple’s Lightning charge and sync cable instead of MicroUSB, as this avoids having to keep two different types of cables — one of which (MicroUSB) is fiddly. We also have a roundup of the best charging cables if you need some suggestions.
