Now that this juicy battery pack is out, we can see how it compares to its competitors!

Fully topped off, this 3.82 V, 1821 mAh cell will deliver up to 6.96 Wh of power.

To compare Apples to Apples, the iPhone 7 featured a 7.45 Wh battery.

And for reference, the similarly-spec'd Galaxy S8 packs a 11.55 Wh battery.

Before you get hopping mad about battery news: despite the drop in capacity, Apple claims battery life will be comparable to last year’s unit.
