Still can't decide on what you want? Our round-up of the best iPhone cases can help you find what you're looking for.

Best for iPhone X/XS: Smiphee iPhone X/XS Battery Case

You paid good money for your new iPhone X, which means you need a case that prioritizes protection above all else. The Smiphee self-charging case for the iPhone X/XS holds a modest 4,000mAH battery, which can extend your phone’s battery by an extra day. However, its main draw is in the design. With its “chinless” frame, the Smiphee can easily pass for a standard iPhone case. It’s made with a soft, rubber material that is highly durable, yet light-weight. Additionally, the raised bezel edges around your phone’s screen and camera lens add an extra buffer, protecting the glass from shattering on the hard concrete.

The Smiphee also offers a decent level of compatibility with your iPhone’s features. It supports sync-through charging and works with both wired and Bluetooth headphones. Additionally, the product is backed by a 12-month money-back guarantee, so you have plenty of time to test-drive your new, long-lasting battery pack.

Best Budget for iPhone X/XS: Trianium Atomic Pro iPhone X/Xs

It’s not every day that a budget-friendly product can go toe-to-toe with higher-end models, but the Trianium Atomic Pro is the exception to the rule. This case offers great value, featuring similar specs to competitors that are twice its price. It holds a 4,000mAH power bank, which effectively doubles your phone’s battery. Broken down, this equates to eight hours of talk time or 11 hours of web browsing. Its two-piece design makes the installation process quick and easy—they just snap right into place. Removing the case is also a painless procedure, but since the Trianium supports sync-through charging, you may never have to.

The Trianium Atomic Pro offers 360-degree protection, featuring a harden backplate and a shock-absorbent bumper. Clumsy phone users can rest easy because their valuable devices are fully protected. At the same time, the case fits snugly into your palm or pocket, thanks to its ultra-thin design.

Unfortunately, the Trianium is limited in terms of compatible features: It doesn’t support wireless charging or CarPlay, and only works with Apple AirPods and other Bluetooth-headphones. These are small inconveniences, so if you can look past them, then you can save some money by choosing this reliable battery case.

Best for iPhone 7/8: HETP Battery Case for iPhone 8/7

You would never guess that a budget-friendly battery case could contain so much power. With its 6,000mAH, the HETP iPhone 7/8 case exceeds expectations for its price range, increasing your phone’s lifespan by 200 percent. Still, the HETP case’s merits don’t rest on its battery power alone. The product is made with highly durable materials, and although a bit bulky, it offers heavy-duty protection. Its exterior shell stands up to daily wear and tear, but more importantly, it contains an internal chip that regulates your phone’s temperature, protecting against overheating, overcharging, and short-circuiting.

The HETP case utilizes the convenience of sync-through technology, allowing you to charge both your phone and the battery case simultaneously. Simply insert your iPhone’s lightning output connector, just as you would when charging any other device.

Also, the HEPT case includes an LED indicator to track its battery power, so you’ll always know when your phone is fully charged and ready to go.

Measuring 0.6 inches thick and weighing 5.6 ounces, the lightweight Lonlif battery case for the iPhone 7/8 does not underestimate the importance of design. Its durable, scratch-proof shell and raised edges offer well-rounded protection without adding unnecessary bulk. Also, its two-piece magnetic frame slides easily onto your phone, so there’s no struggle when it comes to the installation process.

Since the case is so thin, you have to compromise slightly on battery power. The Lonlif’s 4,000mAH battery adds an extra 120 percent to your battery, providing an additional 16 hours of talk time, 14 hours of web browsing, or 48 hours of audio listening. The case will easily extend your charge by a full day, and since it uses a manual on/off switch, you can utilize that extra power more effectively.

Additionally, the Lonlif features sync-through charging, so you can recharge your phone and your case simultaneously. It’s also compatible with the standard iPhone cable and Apple’s wired EarPods, unlike other devices, which are purely wireless and require their own charger.

Best for iPhone 7/8 Plus: Alpatronix BX190plus 5.5-inch 5000mAh

Alpatronix is already a well-respected brand of iPhone battery cases and its BX-series offers several different versions to accommodate various iPhone models. The BX190plus, made exclusively for the iPhone 7/8 Plus, however, features the best battery in the collection. With an energy capacity of 5,000mAH, the BX190plus extends your phone’s lifespan by 150 percent. Additionally, this device offers more compatibility features than the standard iPhone battery case.

It supports Qi-wireless charging, which is less common among these battery cases but also works with the Apple-certified micro USB connectors. It’s also compatible with Apple Pay and supports all future iOS software updates. The one downside is that this charging case is a purely wireless device; there’s no input for wired earbuds, so you need to have a pair of Apple AirPods on hand.

Touching on design, the Alpatronix boasts a slender, lightweight frame, measuring just half an inch thick and weighing 5.1 ounces. The case comes in two separate units that snap securely onto your mobile device. The front has a raised bezel edge and comes with a tempered glass cover to protect your screen from cracking on the hard asphalt. Meanwhile, the rear end is reinforced with a scratch-proof, shock absorbent buffer.

With the Alpatronix BX-series, you’re surely getting your money’s worth. The brand’s products adhere to high standards in regards to quality, which is backed by its certifications from the CE, RoHS, and FCC.

Best Battery Capacity for iPhone 7/8 Plus: Smtqa Battery Case for iPhone 7/8 Plus

With a whooping 8,000mAH battery pack, the Smtqa charging case delivers one of the highest capacities we’ve seen so far. With this much power, you’re basically tripling your phone’s battery life. The Smtqa provides 17 hours of call time, 13 hours of video-watching, 60 hours of playback, or three hours of 3D gaming, stretching your phone’s charge over several days. On the back of the device, you’ll find a set of four LED lights that track how much power is left in your case. It also includes a manual on/off switch, allowing you to save that extra charge until you absolutely need it.

The Smtqa case is highly durable, boasting 360-degree protection against scratches and drops. Under the hood, so to speak, you’ll also find internal chips that regulate your phone’s temperature, so it won’t overheat or short circuit. The Smtqa case features a standard lighting port, so you can still use a regular charger and earbuds with the device.
