The Samsung Galaxy S8 doesn't have great battery life, so you may be in search of an extra boost of battery life after a long day of use. That's where a battery case comes in real handy, offering you essentially an extra battery pack that's attached to your phone and doubles up with some added protection.
The Mophie Juice Pack Battery Case includes a 2,950mAh battery, along with wireless charging, allowing you to take advantage of your existing Qi charger. Plus, the low-profile design won't add so much bulk that you never want to use the Juice Pack.
Simple and straightforward
A 6000mAh battery is more than double the standard capacity provided by the Galaxy S8, and this battery case from HETP is quite impressive. There is sync-through technology, which makes it easy to charge both your phone and the case at the same time without having to worry about waiting forever for either product to charge.
ZeroLemon is one of the leaders when it comes to external battery cases, and the option for the Galaxy S8 is rather large. The capacity comes in at 8500mAh, with the company stating this will add up to 32 hours of web browsing or an additional 48 hours of talk time.
Mophie decided to do things differently with the Charge Force Magnetic Case. Instead of adding bulk and building the battery into the case, it's more of a modular design. The included 3,000mAh battery will ensure that you get through the day, but you can also use the included case with other modules offered by Mophie.
Sleek with a bumper
The problem with some of these battery cases is that you aren't really able to take advantage of the 3.5mm headphone jack. Trianium solves this with the Atomic Pro by adding a headphone adapter to go along with the 4,500mAh case.
Out of the norm
Some folks don't like the idea of using a black case all the time, but the options are limited when it comes to battery packs. The Maxboost Atomic Power includes a 4,500mAh battery, but also comes in a White/Grey color combination, ensuring that your Galaxy S8 will stand out from the crowd.
