On paper, Apple's upcoming iPhone 12 device may have a rather disappointing battery life, with only the iPhone 12 Pro Max exceeding 3,500 mAh In fact, the leaked battery size is smaller overall for the iPhone 12 versus the iPhone 11 But battery capacity is only part of the equation

MySmartPrice was able to confirm the size of the battery pack that the iPhone 12 model is supposed to have based on 3C and related certification codes with battery details for four iPhone devices And given that these next-generation Apple phones are expected to feature 5G connectivity, the rather constrained battery pack size is somewhat surprising

The iPhone 12 Pro Max will have the largest battery pack at 3,687 mAh; the 61-inch iPhone 12 Pro and iPhone 12 Max will have a 2,775 mAh battery, and the smallest 54-inch iPhone 12 will reportedly have a 2,227 mAh battery in the smallest 54-inch iPhone 12, which reportedly has a 2,227 mAh battery

Compared to other flagship smartphones, such as Samsung's Galaxy S20 and its 4,000 mAh battery and the OnePlus 8 Pro's 4,510 mAh battery pack, even the iPhone 12 Pro Max looks rather lackluster battery-wise Battery size and battery life are especially important in 5G phones, as the connection to next-generation cellular broadband can consume a phone's battery rapidly

Therefore, the battery specifications for the iPhone 12 series may end up being a bit disappointing previous leaks suggesting a high-powered charger for the iPhone 12 had predicted a battery large enough to rival flagship Android phones

However, the battery is not expected to be as large as the flagship Android phone

However, there are efficiency and optimization issues to consider here The longest-lasting battery models last 11-12 hours in a custom web-surfing battery test, in which web pages are repeatedly loaded via cellular network and used until the battery runs out

The Galaxy S20 Ultra with its huge 5000mAh battery can make the list, and the OnePlus 8 Pro lasted a very long 11:05 on a 60Hz mode display However, the Galaxy S20 (4000 mAh) and Galaxy S20 Plus (4500) lasted only 9:31 and 10:31, respectively

However, both the iPhone 11 Pro Max and iPhone 11 made the list iPhone 11 Pro Max has a 3,969 mAh battery, which is large, but not huge, compared to current flagship models And the iPhone 11 has a relatively small 3,110 mAh battery

This is a testament to Apple's software optimization and efficient performance from its chips With this in mind, the seemingly small battery size of the upcoming iPhone 12 device may not matter as much, especially since the new 5nm A14 Bionic chip should be even more efficient

Of course, there are new factors such as the addition of 5G and the possibility of a 120 Hz display on the iPhone 12 Pro model, but for now, we should not be too concerned about these leaked battery capacities for the iPhone 12
