Best battery cases for Samsung Galaxy S8 and S8+

While the Samsung Galaxy S8 and Galaxy S8+ offer adequate battery life (particularly the S8+), there are times when you may need your phone to keep its lights on longer than it normally does. For those times, you might want to purchase a battery case - which, of course, will also keep your S8 or S8+ safe from drops, bumps, scratches, and other potential dangers.

If you do need a battery case for your Samsung Galaxy S8 or S8+, we think that the options presented below are among the best currently on the market. Obviously, the cases that you'll discover here will make your handset quite thick, but that's what you have to live with if you want protection and extended battery life in a single product. The cases are listed in no particular order.

Mophie Juice Pack Case

Buy ($99.95): Galaxy S8 | Galaxy S8+

A Mophie Juice Pack case can almost double the battery life of your Galaxy S8 or S8+ (thanks to built in cells of 2,950 mAh and 3,300 mAh, respectively). The case looks pretty stylish, provides edge-to-edge protection, and supports wireless charging. Magnetic mounts, LED power indicators, and 2-year warranties come with each Mophie Juice Pack case for the S8 smartphone family.

ZeroLemon Ultra Power Case

Buy ($59.95): Galaxy S8 | Galaxy S8+

This ZeroLemon case is not among the prettiest products here, and its bulkiness certainly doesn't help in this regard. However, the case excels in one important regard, as it's got an 8500 mAh battery that's ready to nearly triple the life of your phone's battery. You're also getting all-round protection for your handset, and an LED power indicator. All cases come with 180 days (6 months) ZeroLemon Guarantee Warranty, as well as a 30-day Amazon full refund guarantee.

Trianium Atomic Pro Case

Buy: Galaxy S8 ($35.99) | Galaxy S8+ ($39.99)

The Trianium Atomic Pro cases can double the battery life of your Galaxy S8 or Galaxy S8+, as they include 4500 mAh, and 5000 mAh cells, respectively. These are two-piece cases, including a bumper frame and a hard-shell backplate for comprehensive protection. An LED battery level indicator is on board, too. Unfortunately, the Trianium Atomic Pro won't let you charge your Galaxy S8 wirelessly, but at least fast charging is supported. Oh, and you're also getting lifetime warranty.

BrexLink Battery Case 

Buy ($39.99): Galaxy S8 | Galaxy S8+

Here's another reliable case that will double the battery life of your beloved Samsung Galaxy S8 or Galaxy S8+ (thanks to 5000 mAh, or 5500 mAh capacities). Made by BrexLink, the case will do a fine job at keeping your phone safe, as well as at preventing overheating when charging. 1.5-year warranty is included.

WingYeah Slim Battery Case

Buy: Galaxy S8 ($34.99)

At 0.55 inches (14 mm), this WingYeah case is thinner than all the other options on this list, and yet it still manages to pack a 4200 mAh battery inside. The case is quite elegant, comes with 1-year warranty, and can be purchased in three color versions: black, black pearl, and pink. Sadly, the WingYeah case is available only for the Galaxy S8, so S8+ owners have to look elsewhere.

Speaking of battery, just-as predicted, battery capacity doesn't tell the whole story of how long a device will last: Now the ignorant haters can shut their traps.
