5 Best Galaxy S9 Battery Cases

Mophie Galaxy S9 Juice Pack ($99)

One of the most popular and trusted name in smartphone accessories, especially battery cases, is Mohpie. They're one of the original battery case manufacturers. 

What makes their case better than most is you don't lose any features. With the Mophie Juice Pack for the Galaxy S9, you still get wireless charging, NFC, Bluetooth, and fast charging technology. Yes, fast charging works through the case. The downside to keeping those helpful features though is there's only an extra 2,070 mAh of battery in the case. It's smaller than some, but you get to keep all the features you love. 

Meaning the Galaxy S9 goes from 3,000 to a little over 5,000 mAh with the Mophie case. That said, it's also a better case, better brand, and higher quality battery. It's also one of the thinnest battery cases available.
