power bank with you, but they’re hardly pocketable and that’s just one more thing to lug around. For true mobility and peace of mind, you’ll need a battery case. Not only do these battery-infused cases keep your smartphone charged, but they also keep it protected as well. Here’s a list of some of our favorites.
TL;DR – These are the Best Smartphone Battery Cases:
1. Alpatronix BXX
Best iPhone XS Battery Case
When you’re dealing with third-party peripherals and Apple products, it’s important to remember Cupertino has a tendency to release updates which spawn the dreaded incompatibility message on-screen. While the Alpatronix BXX isn’t “Made for iPhone” certified, it does use a certified connector, which is a big help. This 4200mAh battery case will give your iPhone XS or iPhone X an extra full charge and even better, it’s Qi compatible for wireless charging without removing the case.
2. ZeroLemon Rugged Juicer
Another Great iPhone XS Battery Case
ZeroLemon Rugged Juicer
A Rugged Juicer might sound like a steroid-addled lumberjack, but it’s actually this very high capacity battery case from ZeroLemon. While the Rugged Juicer isn’t capable of wireless charging—you’ll have to remove the case for that—it does have a massive 8000mAh battery. That’s enough to charge your iPhone XS or iPhone X twice, so wireless charging will be the least of your worries. As mentioned above, the Rugged Juicer isn’t Made For iPhone certified, but its connector is Apple certified.
3. Apple Smart Battery Case
The Offiicial Apple iPhone XS Battery Case
Apple Smart Battery Case
While there’s generally added value and possibly aesthetic advantages to third-party battery cases, for the iPhone XS and iPhone X, you really can’t go wrong with Apple’s Smart Battery Case.
The 2,365mAh battery will almost recharge the battery fully, and it is (obviously) MFi certified. One of the biggest advantages over a third-party case is the inclusion of a Lightning port, so you can use Lighting headphones and earbuds no problem.
4. Mophie Juice Pack Access
Best iPhone XS Max Battery Case
Mophie Juice Pack Access
The iPhone XS Max has a bigger battery than Apple’s ‘regular-sized’ iPhone XS, but it never hurts to have even more battery life at the ready. The Juice Pack Access gives your handset an additional 2,220mAh of portable power.
That translates to about 18 more hours of video playback or 16 additional hours of web browsing. The Mophie Juice Pack Access also works with Qi-compatible charging pads, so you can charge your phone and case at the same time.
5. Trianium Atomic Pro
Best iPhone XR Battery Case
Trianium Atomic Pro
Packed with a fat 4200mAh battery, the Trianium Atomic Pro is an excellent battery case for iPhone XR users. You can charge the case and phone together using a micro USB cable, which is kind of a bonus in since you can ditch the Apple-specific Lightning cable.
Another bonus of this case is it also has wireless charging built-in, so it’ll work with all the Qi wireless charging pads you’ve already own. I’ve been using this case for about six months now and couldn’t be happier. And despite the long battery life, it’s still surprisingly slim.
6. ZeroLemon Slim Power
Best Samsung Galaxy S10 Battery Case
ZeroLemon Slim Power
The ZeroLemon Slim Power battery case for the Samsung Galaxy S10 packs a ton of power. With a 5,000mAh battery life, the Atomic Pro will keep you moving without freaking out about not carrying a charger. But when you do charge and sync, this case is fully fast charge compatible with the phone still in the case.
7. Alclap Google Pixel 3 Battery Case
Best Google Pixel 3 Battery Case
Alclap Google Pixel 3 Battery Case
While most battery cases on this list will simply add a single recharge to your smartphone, the Alclap Google Pixel 3 Battery Case will actually give you a 125% boost, thanks to its 4,700mAh battery.
There’s a nice front-facing bumper to keep your screen safe, and this charger is also fully capable of charging the case and your Pixel 3 together with a single USB-C cable. And while it’s certain to add some extra girth to your Pixel, this case is still lightweight and has a nice soft-touch feel.
8. Newdery Slim Charging Case
Best LG V30 Battery Case
Newdery Slim Charging Case
There is a surprising dearth of battery cases for the LG V30, but this slim charger from Newdery is a solid option. It isn’t compatible with wireless charging, but the 4,200mAh battery will recharge your phone completely on the go. There’s a lifetime warranty and you can sync and charge your V30 without removing it from the case. But the most impressive feature of this case is its small size, adding just 0.4 of an inch to the V30’s profile.
