In this buying guide, we’ll explain the benefits of a Galaxy S8 battery case and share a list of the best Galaxy S8 battery cases available. These cases will keep your phone safe and nearly double its battery life at the same time.
With a big curved display and glass covering the front and the back, the Galaxy S8 can easily get damaged. That’s why we recommend getting a good case, and while you’re at it one that extends battery life.
There are a few different choices for a battery case, from cheap no-name brands that may not last as long as advertised, to quality cases from brands we know and trust. We’ve found options as low as $36 although you’ll need to spend $99 to get a battery case from a reputable brand.
Last year Samsung debuted their own battery cases for the Galaxy S7 and S7 Edge with wireless charging built-in. So far though, there has been no sign that the company will be offering that same accessory this year. As a result, owners will need to look to popular third-party accessory manufacturers.
The Galaxy S8 and S8+ come with a large 3,000 and 3,500 mAh battery packed inside. However, like earlier devices that battery is no longer removable. As a result, the best thing for users is a portable battery charger, or a Galaxy S8 battery case.
Buying a cheap $36 battery case is better than nothing, and will keep your screen safe from drops and other damage, and it’s far cheaper than spending $200 or more to replace a broken screen. More expensive options like Mophie offer wireless charging built-in, so you won’t lose any features and still have protection.
These cases can make the Galaxy S8 last for 2-3 days on a single charge. Perfect for road warriors, business users or someone on vacation. Even if you don’t use it daily, a battery case is a good accessory to have when you need it.
Considering the Galaxy S8 and S8+ is still fairly new the options are somewhat limited. That said, some of the best brands have released great cases worth considering. As more get released we’ll update the slideshow below. For now, these are the best Galaxy S8 battery cases that will let you use your phone longer than ever before.
i-Blades Smart Case
First up is a unique case from the guys at i-Blades. They actually call it a "smart case" for one of the smartest phones on the planet, the Galaxy S8.
The i-Blade Smart Case for the Galaxy S8 does a lot more than just extend the battery life. It's a traditional thin case that offers decent protection, but then there are four connection points on the back that allow modules or "blades" to snap on. It isn't extremely pretty, but the blades add a lot of value.
For $99 the i-Blade Battery attachment adds 12 hours of battery life, 64GB of storage (so 128GB total) and a second microSD slot for even more storage. Technically with their case, the Galaxy S8 can last nearly two days and have over 600GB of storage in total. Pretty neat right?
The case also has sensors to monitor air quality around you, and there will be more snap-on blades released at a later date.
