While Apple consistently leads in global smartphone technology, battery capacity has been a perennial concern for users of this flagship device. Besides the price, the battery size of iPhone 13 is a critical aspect that captures user attention.
Although Apple doesn't officially disclose the battery capacity of its iPhone lineup, experts estimate the following based on publicly available information:

– iPhone 13 mini has a battery capacity of 2425 mAh
– iPhone 13 has a battery capacity of 3240 mAh
– iPhone 13 Pro boasts a robust 3125 mAh battery capacity
– The iPhone 13 Pro Max packs an impressive 4373 mAh battery
Specifically, Apple has officially disclosed the usage duration for the iPhone 13 series as follows:
The battery life of the iPhone 13 Pro Max surpasses that of the iPhone 12 Pro Max by 2.5 hours, precisely
+ Up to 28 hours of livestream video viewing time
+ Up to 95 hours of music playback time
iPhone 13 Pro Max still uses the lightning charging port, supporting fast charging up to 20W, MagSafe wireless charging at 15W, and Qi wireless charging at 5W.
The iPhone 13 Pro's battery life exceeds that of the iPhone 12 Pro Max by 1.5 hours, specifically:
+ Up to 22 hours of livestream video viewing time
+ Up to 75 hours of music playback time
iPhone 13 Pro also features the lightning charging port with fast charging up to 20W, MagSafe charging at 15W, and Qi fast charging at 5W.
The iPhone 13's battery life surpasses that of the iPhone 12 by 2.5 hours, precisely:
+ Up to 19 hours of livestream video viewing time
+ Up to 75 hours of music playback time
Just like its predecessors, the iPhone 13 comes with 20W fast charging technology, MagSafe wireless charging at 15W, and Qi wireless charging at 5W.
The iPhone 13 mini's battery life surpasses that of the iPhone 12 mini by 1.5 hours, specifically:

iPhone 13 mini also incorporates full 20W fast charging technology, 15W MagSafe fast charging, and Qi wireless charging technology at 5W.

Thus, all members of the iPhone 13 family recently unveiled by Apple have seen significant improvements in battery life, surpassing their respective predecessors. This is attributed to three main factors:
Firstly, the batteries used in the iPhone 13 series are larger than those in their predecessors, contributing to an increase in thickness compared to the older generation.
Secondly, optimization in the processing chip enhances power efficiency, contributing to battery conservation.
Thirdly, software optimization is also a positive aspect that allows iPhones in general, and the iPhone 13 in particular, to have excellent power-saving capabilities.
However, when compared to the current market trend of Android smartphones with battery capacities up to 6000 mAh or even higher, the iPhone 13 still faces a weakness in battery capacity.
The iPhone 13, along with the iPhone 13 mini, iPhone 13 Pro, and iPhone 13 Pro Max, was officially unveiled by Apple in an event on September 14th. It brings users a new iPhone that may not differ much from its predecessor. However, performance upgrades with the Apple A15 chip and improvements in the camera promise users an even better experience with this new iPhone generation.
Currently, official Apple distributors in Vietnam have released the official prices for the iPhone 13, and the selling prices do not differ much from its predecessor. The iPhone 13 is expected to officially arrive in Vietnam in October 2021.
