Apple is and has always been notorious for not publishing the actual battery capacities of its smartphones in the official specifications. So if you’re interested in the exact numbers for the new iPhone 15 series, you usually have to wait until the first people pick up their new iPhones and then take them apart.
Alternatively, you can wait for Chinese regulators to certify the new iPhones for sale in the country. Such certification is exactly what has just appeared. And the fact revealed that all four iPhone 15 models have slightly larger batteries than their predecessors.
The cell of the regular Apple iPhone 15 has a capacity of 3,349 mAh, compared to 3,279 mAh for the iPhone 14. The iPhone 15 Plus has 4,383 mAh, compared to 4,325 mAh for the iPhone 14 Plus. The battery capacity of the iPhone 15 Pro is 3,274 mAh, compared to 3,200 mAh for the iPhone 14 Pro. Finally, the iPhone 15 Pro Max beats them all with its 4,422 mAh battery. It went up from 4,323 mAh in the iPhone 14 Pro Max.
As you can see, these increases are tiny. A 100 mAh or 2-3 percent larger battery will not make a noticeable difference in practice. So if there are significant improvements in battery life, they will most likely come from more efficient chipsets and displays.
The Apple iPhone 15 and iPhone 15 Plus, as well as the iPhone 15 Pro and iPhone 15 Pro Max, were unveiled on Tuesday at a major event at Apple’s headquarters in California. Since then, pre-orders have been underway in dozens of countries around the world.
