iPhone 14 battery sizes

In a filing on the Chemtrec website, Apple has published official details on the battery sizes of each of the iPhone 14 models. As expected, the iPhone 14 Plus battery is particularly impressive. There are also increases for the iPhone 14 and iPhone 14 Pro, while the battery in the iPhone 14 Pro Max is actually slightly smaller.

Here is the watt hour capacity for each of Apple’s iPhone 14 models, compared to their iPhone 13 predecessors:

• iPhone 14 – 12.68 watt hours
  • iPhone 13 – 12.41 watt hours
• iPhone 14 Plus – 16.68 watt hours
  • N/A
• iPhone 14 Pro – 12.38 watt hours
  • iPhone 13 Pro: 11.97 watt hours
• iPhone 14 Pro Max – 16.68 watt hours
  • iPhone 13 Pro Max: 16.75 watt hours

The battery life of an iPhone is impacted by two primary factors: the size of the battery life and the efficiency of the processor inside the iPhone. This year, the iPhone 14 Pro and iPhone 14 Pro Max have switched to a new A16 Bionic process that uses a new 4nm manufacturing process. The iPhone 14 and iPhone 14 Plus use the 5nm A15 Bionic, which is still incredibly efficient but less so than the A16 Bionic.

Shrinking the fabrication process used for chip manufacturing generally results in a boost in efficiency. This will obviously counteract the fact that the iPhone 14 Pro Max features a negligibly smaller battery than the iPhone 13 Pro Max.

Some additional statistics on the iPhone 14’s mAh battery stats have also emerged through a regulatory database in China.

• iPhone 14: 3279 mAh
  • iPhone 13: 3227 mAh
• iPhone 14 Plus: 4325 mAh
  • N/A
• iPhone 14 Pro: 3200 mAh
  • iPhone 13 Pro: 3095 mAh
• iPhone 14 Pro Max: 4323 mAh
  • iPhone 13 Pro Max: 4352 mAh

iPhone 14 battery life: What to expect and how it compares to previous iPhones

The four iPhone 14 models feature the same general design as the iPhone 13 and 12 with flat sides. But with the iPhone 12 devices at a thickness of 0.29 inches (7.4 mm) and the iPhone 13 lineup at 0.30 inches (7.65 mm) thick, the iPhone 14 comes in at 0.31 inches (7.8 mm and 7.85 mm for the Pro). That includes a slightly increased battery life along with new camera modules.

iPhone 14 battery life: What to expect

Apple says the iPhone 14 devices offer the “Best battery life ever in an iPhone.”

• 1 hour longer battery life on iPhone 14 Pro than iPhone 13 Pro for video playback
• 1 hour longer battery life on iPhone 14 Pro Max than iPhone 13 Pro Max for video playback
• 1 hour longer battery life on iPhone 14 than iPhone 13 for video playback
• 7 hours longer battery life on iPhone 14 Plus than iPhone 13 for video playback (no direct predecessor for comparison)
