Apple has not provided public information about the battery of the iPhone 12. However, the Brazilian website Tecnoblog claims to have information that does indicate the battery capacity.
‘iPhone 12 battery smaller than its predecessor’
The document, which Tecnoblog has in its hands, shows that the iPhone 12 mini has the smallest battery of the iPhone 12 series. With a battery capacity of 2,227 mAh, it is smaller than, for example, that of the iPhone 11 . The choice for a smaller battery is not surprising, given the compact size of the device.
The same source indicates that the iPhone 12 is equipped with a 2815 mAh battery. This also makes this battery smaller than the 3110 mAh battery of the iPhone 11. What does this say about the final battery life?
Thanks to the new A14 Bionic chip, the battery life remains about the same. The A14 chip is a lot more powerful (and more energy efficient) than its predecessor. The chip has become more compact and more efficient in important parts. Still, it remains striking that Apple opts for a smaller battery.
Why does Apple choose a smaller battery?
In recent years we have become used to the battery getting bigger with every new device. Apple now appears to be moving away from this trend. A probable reason is the choice for a thinner design. With this, Apple partly prefers form over function.
The integration of 5G also affects the ‘shrinkage’ of the battery. This year, Apple is switching completely to 5G, so the iPhone 12 can handle both techniques of the 4G successor: sub-6GHz and mmWave. With this double support, you will always have good mobile coverage, but there are hefty production costs for Apple. In order not to increase the price of the iPhone 12 devices (too much), Apple is cutting costs for other parts, including the battery.
The battery capacity information comes from ANATEL, the Brazilian national telecommunications agency that certifies new electronic devices. Tech website Tecnoblog discovered the document and is now slowly leaking the first bits of information. The website claims to have data on all four new iPhone models. Details about the battery capacity of the iPhone 12 Pro and iPhone 12 Pro Max the website has not yet shared.
