As we examine the battery our heart beats a little bit faster for a second, as we only see a single adhesive strip we need to pull out...

....Well we've been pleased too early. Right under the battery is a big, mean piece of adhesive we need to combat. Luckily our Plastic Cards come in handy!

Now that the battery is out, we can compare it to its competitors! Fully topped off, this 3.82 V, 4000 mAh cell will deliver up to 15.3 Wh of power. The new iPhone 8 Plus has only 10.28 Wh.
