The battery cases will be launched around the time the new Galaxy smartphones are released later this spring for $99.95

[custom:mwc15] Mophie previously launched versions of its Juice Pack battery case for the Samsung Galaxy S3, S4 and S5. Now the company is doing the same for both the Galaxy S6 and the Galaxy S6 edge.

Mophie said:

These latest additions to mophie's juice pack family each offer users more than 100% extra battery life (3300 mAh) and edge-to-edge protection, highlighted by mophie's proprietary Impact Isolation System that acts as an internal suspension system, protecting the device from drops. Along with pass through sync and quick charge capabilities, the design of the juice pack line also maintains the functionality of the S6 and S6 Edge with pass-through buttons and mophie's proprietary mute switch. As part of Samsung's SMAPP program, consisting of strategic accessory partners, mophie will offer the only battery charging case for the S6 and S6 Edge at launch.
