Fast-Charging Algorithms of the iPhone 13 Pro Max and Samsung S22 Ultra

Practical Protocols to Minimize Battery Cell Degradation

Comparative Analysis and Insights by Dr. Ali Khazaeli (Subject Matter Expert, Battery, TechInsights)

Find an analysis of the existing fast charging methods and their associated problems, and an investigation of the fast-charging techniques of the iPhone 13 Pro Max and Samsung S22 Ultra.

Although Lithium-ion batteries are good power sources for portable and wearable electronics, their required time to recharge is still a common concern. High currents are needed to accelerate the charging process; however, these high currents cause accelerated capacity and power fade. Due to this, battery OEMs continue to attempt to develop novel fast-charging algorithms to speed up the charging process without comprising the cyclic life.

Within this eBook, you will find an analysis of the existing fast charging methods and their associated problems, and an investigation of the fast-charging techniques of the iPhone 13 Pro Max and Samsung S22 Ultra. We then explore the reason for the slower charging rate of the iPhone 13 Pro (20W @ ~106min) compared to Samsung (25W @ 70min).

Finally, Dr. Khazaeli explains why we only see a ~10% improvement in charging speed using the 45W compared to the 25W charger and describes the other benefits of using a 45W vs. a 25W charger.
