Best iPhone X Battery Cases to Extend Battery Life in 2021

Mophie makes some of the best battery cases on the market, and the Mophie Juice Pack Air comes packed with great features you'd expect from a high-end battery case. It's low-profile and ergonomic design makes it easy to hold. The LED indicator lights on the back will show you how much battery you have left in the case. Plus, you can charge your iPhone and the Juice Pack Air at the same time using Qi wireless charging. You don't have to charge them with separate cables.

Designed with a protective, 360-degree bumper case, and able to charge your iPhone with the push of a button. This protective battery case will add 15+ hours of talk time or nearly 10+ hours of web browsing time to your iPhone X's battery life. Unlike plenty of other battery cases, the Trianium Atomic Pro is actually quite slim and compact (though it's definitely not designed to be ultra-thin and minimalist).

This case not only will provide you with eight extra hours of talk time thanks to its 3,000mAh battery, but it also features a rubbery textured surface that allows you to grip your phone extra tight. The Maxboost iPhone X Battery Case is designed with a lightweight look and feel, and shouldn't add too much bulk to your iPhone X. Plus, an LED indicator will tell you when your case needs to be charged, If you need to turn it on or off in an instant. You can hit the button at your leisure!

The Alpatronix BXX battery case is great for those who love wireless charging. This case comes packed with 4200mAh of extra juice so that you can get a little more than a full charge from it throughout the day. If you already have a wireless charging pad at home, just place the phone with this case on, and both will charge like magic.

If you care about protecting your iPhone X as much as you care about keeping it charged up, the EasyACC Rugged Battery case wraps your iPhone in solid protection as well as a battery. With a 5,000mAh battery pack, you should be able to get just about twice as much time on your iPhone X before recharging. Plus, its rugged design will ensure that any minor drops or dings won't leave your iPhone X any worse for wear.

Who says a battery case has to look boring? Casely offers several colorful and fashionable battery cases from plaids and florals to animal prints for all you cool cats and kittens out there. Don't let the good looks fool you: this is a 4,000mAh case, enough to give your iPhone X a full recharge.
