Finally, we've reached the iPhone 7's power source. What strange energies fuel this dark obelisk? Magic? The offal of a dying star?

Actually, it's a relatively benign Lithium-ion battery. This 3.8 V, 1960 mAh battery is rated for a capacity of 7.45 Wh—a notable increase from the 6.55 Wh battery in last year's model.

Apple claims that this upgraded cell will provide up to 14 hours of 3G talk time, 14 hours of Wi-Fi internet browsing, and 10 days of standby.

While the improved battery life is great, we're more excited about the fact that this battery keeps its replacement-friendly pull tabs—and that it hasn't blown up on us.
