After surveying almost 1,000 Wirecutter readers and testing 60 iPhone 6 cases over a period of about 30 hours (so far), our current pick for the best all-around case is the NGP from Incipio. The NGP has protected several generations of iPhones (and many other devices) and has a reputation for providing solid protection and a good fit. It's slim enough to not detract from the iPhone 6's svelte dimensions, while still offering comprehensive protection for the handset's body, including its buttons. Openings along the bottom allow for compatibility with a wide range of accessories.
How we decided
Truth is, there are plenty of good iPhone cases out there. A bad case is actually a pretty rare thing. But in looking for a few cases that work for most people, we sought out a case that can adequately protect your phone without adding too much bulk or unnecessary embellishments while doing so. Apple sets forth very specific guidelines for case developers. The main thesis: "A well-designed case will securely house an Apple device while not interfering with the device's operation." It goes into much deeper specifics.
A respectable degree of shock absorption is important, as is a tight fit. The case should cover as much of the iPhone's body as possible, including a raised lip around the glass display to keep it from laying flat on a surface. The best cases offer button protection with great tactility, mimicking or in some instances even enhancing what you'd feel with a bare iPhone. Based on these criteria, plastic shells are automatically out of the picture.
Incipio's $20 NGP is the best iPhone 6 case for most people because it offers full body protection from drops and scuffs while adding minimal bulk. Including the protective lip around the screen, the case adds a little more than 2mm to the total depth of the handset, which is about half the extra thickness of our previous pick, the CandyShell. While those with butterfingers may benefit from the extra protection of the CandyShell's dual-layer design, the NGP's slimmer, but still shock-absorbent design offers the best compromise between protection and aesthetics.
The NGP is made out of a single piece of flexible polymer material that the company calls Flex2O. This sounds fancy, but it's really just a variant of standard thermoplastic polyurethane, which you may know as TPU. But there are a lot of TPU cases that can be had for half as much as the NGP, so why pay extra? It comes down to the little things, like fit, button feel, and quality control. As with all good cases, port openings are properly aligned and the button protection doesn't dampen the clicking sensation. Buttons depress readily without requiring noticeably more pressure. This is important because even a little unpleasantness adds up to a lot of annoyance when repeated dozens of times daily.
Flaws but not dealbreakers
There are only two small issues with the case. The first is the height of the lip. At 0.6mm tall, it falls below the 1mm threshold Apple recommends in its case developer guide. We feel it's large enough to still adequately protect the screen. The other issue is a trifle. There's a black ring around the camera opening, which is meant to help prevent color issues when the flash is used. On our review unit, the paint is slightly uneven. It's not so bad that it'll have an effect on pictures, but perfectionists may notice the uneven paint job.
Other great cases
If you're the type of person who's always cashing in on AppleCare, we suggest something with more protection, like Speck's CandyShell ($35), our previous top pick. The two layers of material--plastic on the outside, rubber on the inside--offer more protection than cases that are just one or the other. It's 10.9mm thick, which puts it on the chunky side, but it doesn't feel as thick as it is and is one of the only cases we tested that meets military drop test standards. There's a wide range of colors available, and variants add rubbery grips (CandyShell Grip), credit card holders (CandyShell Card), or graphic prints (CandyShell Inked).
If you're trying to replace your wallet, we recommend CM4's Q Card Case ($40). Without any cards in it, this case is only about a millimeter thicker than the standard CandyShell. The body is sturdy rubber, and it fits securely while protruding to form a 0.8mm lip. On the back, there's a faux leather pocket that can hold up to three cards, plus some cash. With Apple Pay looming, carrying so few cards is becoming even more viable for most people, making this case more practical than it would've been in the past.
The problem with many cases is they prevent being able to dock with speakers and similar accessories. STM's Harbour ($25) address this problem better than any other case. Similar in its construction to the CandyShell but costing $10 less, this case is smaller in every dimension, and has a matte finish.
The biggest advantage to the Harbour is its flip-open bottom. When closed, the case has one hole for the headphone port and microphone, and a second for the Lightning port. While the openings are large enough to work with many plugs, the bottom 1.25 inches of the case can flip up and away on a rubber hinge, allowing full access for docking or compatibility with larger accessories. It's a best-of-both worlds scenario: full protection during normal use, and proper access when you need it. We tested the strength of the hinge by bending it back and forth 250 times, and saw no wear.
We also have an editor's choice case. Apple's $45 leather case isn't as protective as our other picks, but we like it anyway. Sure, it leaves the bottom edge exposed and won't wear as well over time as plastic (in terms of durability), but it offers enough coverage to protect from the majority of scuffs and minor drops. And at 9mm thick, it's one of the thinner cases around that still has a lip protecting the screen.
While lighter color options will show dirt around the edges perhaps sooner than one might like, one man's "dirt" is another's coveted patina that makes the case more unique. Most importantly though, it just looks and feels great. It's like the difference between a hiking boot and a leather dress boot--the hiking boot is more protective and comfortable, but if you're not hiking, sometimes it's worth forgoing a bit of protection and comfort for style and luxury points. That's why several of our senior editors use it as their day-to-day case.
There are a lot of good choices when it comes to the early batch of iPhone 6 cases, but the best pick is the NGP. Very protective without sacrificing aesthetics, it's going to be the case to beat going forward. We'll continue to test it over the long term and see how it fares as newer cases are released.
