As the announcement of the iPhone 12 lineup nears and leaks consolidate a more final picture of the devices, it seems that battery life may improve across most models in spite of reduced capacities.
International certifications spotted in July seemed to reveal the battery capacities of each of the four iPhone 12 models.
- 5.4-inch iPhone 12 mini (model A2471) – 2,227mAh
- 6.1-inch iPhone 12 (model A2431) – 2,775mAh
- 6.1-inch iPhone 12 Pro (model A2431) – 2,775mAh
- 6.7-inch iPhone 12 Pro Max (model A2466) – 3,687mAh
These battery capacities are notably smaller than the iPhone 11 models they are replacing. Apple improved the capacity of its batteries in the iPhone 11 Pro and iPhone 11 Pro Max last year, which have heavier and thicker batteries than those used in the previous XS and XS Max models from 2018. The iPhone 11 Pro Max had the largest battery life of any iPhone ever, lasting up to five hours longer than the iPhone XS Max per charge. This year seems to reverse that trend.
The iPhone 11 Pro has a 3,046 mAh battery, up from the 2,658 mAh battery in the iPhone XS, but the iPhone 12 Pro moves down to 2,775mAh. The iPhone 11 Pro Max has a 3,969 mAh battery, up from the 3,174 mAh battery in the iPhone XS Max, but down to 3,687mAh on the iPhone 12 Pro Max.
According to these filings, the iPhone 12 mini will have a battery capacity 883mAh smaller than the iPhone 11, and the iPhone 12 will have a capacity 335mAh smaller than the iPhone 11. Even the iPhone 12 Pro suffers from a battery capacity 271mAh smaller than the iPhone 11 Pro, and the iPhone 12 Pro Max has a capacity 282mAh smaller than the iPhone 11 Pro Max. Other
