With the cover dispatched, we pop out the battery with the greatest of ease.

The Galaxy Alpha's Lithium-ion battery is rated at 3.85 V and 1860 mAh, giving it 7.17 Wh of juice.

That's a pretty dramatic decrease from the 10.7 Wh battery in the Galaxy S5.

However the Alpha is closely matched with the iPhone 6, which runs at 3.82 V and 1810 mAh, (6.91 Wh).
