Mophie 3,300 mAh Battery Case
Mophie is by far the biggest name when it comes to battery cases, and they've been our go-to company for a long time. However, Samsung made their own this year, and it's cheaper than a Mophie. Making this a hard choice.
Mophie is a tried and true brand, who's been making these cases for a long, long time, so the extra $10 for the Mophie could end up being a worthy price to pay. It features wireless charging, an LED indicator on bottom to show remaining battery life, and it packs a 3,300 mAh battery inside, only a tiny 100 mAh smaller than Samsung's official case.
That said, the Mophie is $99.95, so costs a little more for slightly less. We are getting a trusted brand with a proven track record of battery cases, so that's something to consider. Like Samsung, Mophie offers one for both the Galaxy S7, and the Galaxy S7 Edge. Below is the link for the Edge variant.
