Battery and Charging
The iPhone 8 houses a non-removable 1821 mAh lithium-ion battery, which, while modest by today's standards, enables up to 14 hours of talk time on 3G networks. The device supports 15W wired charging with Power Delivery 2.0, capable of charging up to 50% in just 30 minutes as advertised by Apple, although real-world charging times may vary.
