Greatest Battery Circumstances for iPhone 7 and seven Plus



The iPhone 7 might be nearly four years old, but as one of the last smartphones Apple made with Touch ID it has remained very popular. 

Running the latest version of iOS and sporting the still-excellent A10 Fusion processor, it has held up particularly well. 

However, one are where you may be feeling some strain is battery life. The iPhone 7 came with just a 1,960mAh battery, while the 7 Plus fared a bit better at 2,900mAh.

While it may have been fine to last a full day when you first bought it, you may be struggling to get more than a couple of hours out of it now. That’s where a battery case comes in. 

One of the iPhone 7 battery cases reviewed 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 we recommend here are compatible with the later iPhone 8, but you can also check out a separate guide to the Best battery case for iPhone 8 and iPhone 8 Plus.

Apple iPhone 7 Smart Battery Case

Apple’s smart battery cases might not hold up to the company’s usual sleek design language, but they are very practical. 

The case has a soft elastomer hinge that makes it super easy to slip the iPhone in and out of the convenient one-piece design. Many battery cases come in two parts, which can sometimes detach and get lost or snap.

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

Unusually, the iPhone 7 draws power first from this case, before using its own internal power. Most other battery cases let the phone drain its own battery first, and then use the extra case battery. The case ensures that the iPhone will have 100 percent charge for as long as possible.

There’s no LED battery life indicator on the exterior of the case, although curiously there is one on the interior. Instead battery status is displayed on the iPhone Lock screen and in the Notification Centre. At first this seemed odd, but you get used to it quickly, and is actually a neat idea.

The iPhone 7 Smart Battery Case has a 2,365mAh charge capacity, which is lower than most battery cases but enough for one full recharge, but no more until it gets charged again itself.

At £99/US$99/AU$149 the Apple iPhone 7 Smart Battery Case is not cheap, but if it both protects your precious phone and gives you enough power for the day then it represents good value, and as it’s made by Apple you can be sure of its build quality and safety.

Mophie Juice Pack Air for iPhone 7

Mophie is the market leader in smartphone battery cases, and it’s great that it now has a dedicated case for the Apple iPhone 7 and iPhone 7 Plus – as well as it’s Hold Force magnetic solution (see further down 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 aligns magnetically with all Mophie Charge Force wireless power accessories (such as the Charging Base £39.95/$39.95). Simply place your Mophie case on any wireless charging base and power is sent to your device directly on contact. 

The wireless charging option is great if you buy one of the optional Mophie charging bases. It adds a level of simplicity to your day by saving you searching for the right cable and getting it into the plug the right way round.

Either wirelessly or wired the phone charges first, followed by the Juice Pack battery. The iPhone 7 model has a battery capacity of 2,525mAh, and the iPhone 7 Plus version 2,420mAh – both enough for a full recharge from a fading battery.

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

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

It does add more bulk to the iPhone than some of the slimmer cases reviewed here. One disappointment is that this case charges via a Micro USB port, and not Apple’s Lightning connector – meaning you have to suffer the usual non-reversible Micro USB fumbling, and need an extra cable lying around when you need it (unless you go for the wireless-charging option). It’s also a two-part case design, which is not a great hardship but one-piece designs do seem 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 both the iPhone 7 and 7 Plus. 

Fuze Case

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

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

While allowing Apple more design freedom this does mean that iPhone 7 users have to buy expensive Bluetooth headphones. And with the adapter installed you can no longer both listen to music and charge or sync your phone.

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

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

The case is super slim and its 68g weight (without phone) is noticeably lighter than the 101g Apple Smart Case.

At present only the Black case is available, but Blue, White, Gold, and Pink cases will be available in March 2017.

At the moment Fuze is awaiting Apple’s MFI accreditation and so not all the promised features work. So until this is sorted out your headphones microphone and inline controls do not work, and the Lightning port will only allow for charging. Syncing and audio transfer do not work. On top of this an error message might pop up. The promised headphone integration doesn’t also work, so while this is a nice, slim battery case we don’t think it’s doing much else, despite the claims!

There’s a deal right mow where the Fuze Case is priced at just US$49 instead of the US$90 RRP, but from a recommendation point of view we’d wait until Apple approves the Fuze Case before purchase, and the case is updated to work properly. International shipping outside of the US is $15. Buy direct from Fuze.

Ekrist

A 6000mAh capacity means it should be able to charge both the regular and Plus model at least twice, while LED indicators give a quick overview of how much juice is left. 

As with many battery cases, upon connection to the power your iPhone will be charged first, before the case is juiced up. 

It also boasts a 360-degree scratch guard, meaning it can stand up to the task of everyday wear and tear. 

The standard 4.7in compatibility means it will also fit the iPhone 8, 6 and 6s, but none of the Plus models. 

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

Fey-EU

With so many third-party iPhone battery cases sporting 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 supports the 8, 6 and 6s too. 

Its key selling point over other battery cases is durability. The hard shell design provides military-grade protection, while a soft bumper inner provides support for the most fragile areas of your phone. 

A 3100mAh capacity is plenty for the iPhone 7 to get a full charge and have plenty of room to spare, although it doesn’t support for the 7 Plus. 

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

iPhone 7 battery case buying guide

There are plenty of things to look out for when buying an iPhone 7 battery case. Here are four key areas to keep in mind. 

Power

It’s not quite as simple as it sounds but look for a large battery capacity in the case. It needs to be at least 2,000mAh (milliamp hours), but that would just scrape a full recharge, and more likely give you just 80 percent more juice – enough but there’s better out there. See dedicated articles on phone battery charging tips and tips to boost iPhone battery life.

Protection

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

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

Design

Look for lightweight and slim battery cases if you value the iPhone’s naked statistics. You usually sacrifice some slimness for extra battery capacity.

Charging cable

Try to choose a battery case that uses Apple’s Lightning charge and sync cable rather than MicroUSB as that avoids having to keep two different types of cable – one of which (MicroUSB) is fiddly. We also have a round up of the best charging cables if you need a few suggestions.
