In terms of autonomy, we should not expect a miracle from the iPhone 12 mini. Apple announces indeed times in video playback, video streaming and audio playback less important for this model than for the other three devices of vintage 2020. And for good reason, it is difficult to fit a large battery in a small device of 5, 4 inches (read: iPhone 12 mini, mini autonomy).
ANATEL, the Brazilian certification agency equivalent to the US FCC, today released some information about the iPhone 12 mini. And in particular the battery capacity: it is 2,227 mAh, or 18% more than the battery of the iPhone SE 2020 (1,821 mAh). The iPhone 12 will be better equipped, with a 2,815 mAh battery. The iPhone 11 integrated a 3,110 mAh component, compared to the 3,046 mAh for the iPhone 11 Pro, which is smaller with its 5.8-inch screen.
It's difficult to make a final judgment on the autonomy of the iPhone 12 mini without having tested it thoroughly. However, it will be necessary to wait until November 13 to be able to play with it (the precos starting on November 6). But we will undoubtedly be somewhere between not too bad and without more. The document also mentions Brazilian and Indian production of the iPhone 12 Pro, in addition to Chinese manufacture.
