Apple uses smaller batteries in the iPhone 12 series than in the previous generation.
So compared to the iPhone 11, the iPhone 12 now has only one battery with 2815 mAh (depending on the source also only 2775 mAh) instead of 3110 mAh before – a reduction of about 10 percent. The iPhone 12 Pro should have the same battery size as the normal 12.
Smaller batteries but almost the same running time?
The larger 12 Pro Max model has a 3687 mAh battery, about seven percent less than the 11 Pro with 3.969 mAh. Still these numbers are to be regarded as not final, since there are still no teardowns of the new models.
Apple however indicates at least one hour less battery life on the comparison side of the iPhones. Interestingly enough, the battery life of the iPhone 12 drops during streamed video playback
and on the Pro model during normal video playback.
So the 12 series models will most likely not quite reach the very good battery life of the 11 series models. We’re curious how the smaller batteries will work together with the new displays with much higher resolution. In addition, the 5G usage should also draw some energy. If the real runtimes are only slightly different from the previous models, Apple might have succeeded in optimizing the internal components very well.
