As opposed to Android manufacturers, Apple does not publicly disclose the exact capacity of the battery inside its iPhones. Instead, the company only listed down their battery life in the form of operational hours.
The information is not something that you can easily find within iOS settings as well. So, if you are hellbent on finding the exact capacity of the battery, you have to pop up your iPhone and look directly on the battery cell’s label, as per what you can see on the teardown guides by iFixit.
But sometimes, there are other parties who would list down the information. In the latest example, Vodafone Netherlands has revealed the battery capacity for all four devices within iPhone 12 and iPhone 12 Pro Series right on its website:
If these figures are true, this means that the battery capacities for the new iPhone 12 and iPhone 12 Pro Series are much lower than its predecessor. As a comparison, the iPhone 11 Pro Max carried a 3969mAh battery while iPhone 11 Pro and iPhone 11 were equipped with 3046mAh battery and 3110mAh batteries, respectively.
If the information regarding the battery capacities is true, it is rather interesting how iPhone 12 and iPhone 12 Pro Series managed to match or come very close to the battery life of their predecessors. For example, the battery life figures on Apple’s website stated that both iPhone 12 Pro Max and iPhone 11 Pro Max has similar battery life at up to 20 hours for video playback.
As for other models, the iPhone 12 Pro’s battery life is rated at 17 hours as compared to iPhone 11 Pro’s 18 hours but iPhone 12 and iPhone 11 have similar video playback rating at 17 hours. On another hand, iPhone 12 mini is listed at 15 hours which is slightly shorter than iPhone XR but still two hours longer than the 2nd gen iPhone SE.
Apple has been touting the power efficiency of its new 5nm A14 Bionic chip which could be one of the main reason why iPhone 12 and iPhone 12 Pro Series still has roughly the same battery life as per their predecessors. Nevertheless, let’s see how all those figures will hold up in real life when the new phones become available to customers later this month.
