With the launch of iPhone series 12, the company confirmed that they have reduced the battery size in the phone to make it slimmer and have made a lot of optimizations in the software and hardware to drain less battery, giving a better battery life. However, when users started using the phone, it seems that the iPhone 12 battery lasts even less than the iPhone 11 battery. Also, when it comes to 3D games, which the phone is capable of doing, the battery performance degrades to a new low.
When tested with 3D games on the iPhone 12 and Pro models, the phone only lasted for 3 hours and 1minute, while the same on iPhone 11 Pro lasted for 6 hours and 38 minutes. On the same platform, the iPhone 11 lasted 7 hours 37 minutes, and even the iPhone SE 2 lasted for 5 hours. When we compare the gap between the models, it seems that the gap is too big. Similarly, when we look at an Android smartphone like Xiaomi Mi 10 Pro, it can last around 10 hours playing 3D games.
When it comes to browser runtime, both the iPhone 12 and iPhone 12 Pro gives a time of 12 hours and 33 minutes. Also, while streaming videos from platforms like videos, you will get the time of 6 hours and 38 minutes in the iPhone 12 and 10 minutes more in 12 Pro. The results clearly show that the battery performance in the iPhone 12 series is a downgrade from what it already was and they were mostly betting on the power-efficient A14 Bionic chipset to increase the battery life.
