      The iPhone 7 plus uses a 2,900 mAh battery, giving a quoted talk time of 21 hours using 3G, or around 13 hours on the internet. This is about 5 low-cost AA batteries, or slightly more than a high-end (expensive) alkaline AA battery, and an increase of about 250 mAh from the battery of the iPhone 6 plus. In terms of physical size, it takes up around half of the phone’s volume. I’ll let you decide whether the battery’s capacity is big enough or not!
