Apple is often quite muzhana in disclosing technical specifications of its products. One of the information the company usually omit is battery capacity, and this year there is a good reason for this: the iPhone 8 battery is marginally smaller than the iPhone 7 battery.
According to TENAA, the communications regulator in China (similar to Anatel in Brazil) homologating products that will be launched in the country, the iPhone 8 will have a battery of 1,821 mAh, while the iPhone 8 Plus will have a battery of 2,675 mAh.
This means a 7.1% reduction compared to the iPhone’s 1,960 mAh battery and 8.6% compared to the iPhone 7 Plus with a capacity of 2,900 mAh.
Apple, however, says that this should not reduce the time it takes to use the phone. From the company’s metrics, a single recharge of the iPhone 8 should provide approximately the same time of use of an iPhone 7, and the same goes for the Plus models.
But if the battery is less, how long can usage be the same? Through optimization of hardware and software it is possible to make the device consume less energy. The Bionic A11 processor uses a 10-nanometer versus 16-nanometer process from the A10 processor, from last year’s model, which allows it to achieve better performance using less power.
It’s a similar situation to the view on the Galaxy S8 and Galaxy Note 8 compared to last year’s cell phones. Fearing new disasters such as Note 7, Samsung was more conservative in its batteries and came to diminish them, but without causing loss of autonomy, thanks to the reduction of 14 nm to 10 nm of the processor.
