- iPhone 11 Pro: Up to 18 hours of video playback or 11 hours of internet use.
- iPhone 11 Pro Max: Up to 20 hours of video playback or 12 hours of internet use.
One of the major improvements with the iPhone 11 series was Apple’s shift to the A13 Bionic chip. This chip offered better power efficiency, which paired perfectly with the larger batteries in the iPhone 11 Pro models. Despite the fact that the iPhone 11 Pro had a slightly smaller battery than the XS Max, the A13 chip’s efficiency resulted in superior overall battery performance.
iPhone 12 Series: 5G and Improved Battery Life
The iPhone 12 series, launched in 2020, brought 5G connectivity to the iPhone lineup for the first time. Apple also introduced the Ceramic Shield front cover, which is tougher than previous glass materials, and the return of the flat-edge design that reminded many of the iPhone 4.
With the introduction of 5G, one might expect battery life to decrease, but Apple had other ideas. With the combination of a new 5nm A14 Bionic chip, OLED screens across all models, and software optimizations, Apple ensured that the iPhone 12 series maintained strong battery performance despite the added power demands of 5G.
Battery Capacity:
- iPhone 12 Mini: 2,227 mAh
- iPhone 12: 2,815 mAh

- iPhone 12 Pro: Up to 17 hours of video playback.
- iPhone 12 Pro Max: Up to 20 hours of video playback.
Despite the smaller battery in the iPhone 12 Mini, the phone still managed to offer good battery life thanks to the A14 Bionic’s efficiency. The Pro models had larger batteries, offering longer battery life for power users.
iPhone 13 Series: Battery Life That Lasts All Day
The iPhone 13 series, introduced in 2021, made significant strides in battery life. The iPhone 13 models were powered by the A15 Bionic chip, which not only boosted processing power but also enhanced battery efficiency. Additionally, the physical size of the batteries was increased, contributing to longer battery life overall.
Battery Capacity:
