Battery capacity for new iPhone models
Apple does not provide official information to the public about the battery capacity of its devices. However, this does not prevent us from obtaining such information. This time too.
According to the documentation of the Brazilian telecommunications agency ANATEL, which certifies electronic devices before they are sold in this country, iPhone 12 mini has a 2227 mAh battery and iPhone 12 is equipped with a 2815 mAh battery.
This information was obtained by the editors of the Brazilian service Tecnoblog. What's more, they claim that the documentation they had access to includes data on the batteries installed on the new Pro Series iPhone, but they don't want to share them yet.
By comparison, iPhone 11 is equipped with a 3110 mAh battery, slightly larger than the latest model. A little better in comparison with older models, the mini one. Its battery is over 400 mAh larger than in the case of the new iPhone SE.
