Structural integrity is provided by a midframe, which also houses the power source that makes this galaxy spin.

With the push of a finger, we can pop out the 3.85 V battery with its 472 mAh offering 1.81 Wh.

That means this Galaxy surpasses the 1.47 Wh of the Gear S3 (380 mAh @ 3.85 V) and the 1.113 Wh of the Apple Watch Series 4 (291.8 mAh @ 3.81 V).
