Autonomy OnePlus 9 Pro, Galaxy S21 Ultra, iPhone 12 Pro Max

YouTuber PhoneBuff once again compared the autonomy of flagship smartphones. This time, top models from OnePlus, Samsung and Apple clashed in a battle of endurance.

In terms of characteristics, defeat iPhone 12 Pro Max seems inevitable: its battery has a capacity of only 3,687 mAh versus 4,500 mAh for OnePlus 9 Pro and 5000 mAh at Galaxy S21 Ultra. All three smartphones received 5nm processors (Apple A14 and Snapdragon 888), as well as similar screen sizes: 6.7 inches for the iPhone and OnePlus and 6.8 inches for the Galaxy. However, the Apple flagship has a slightly lower display resolution and a refresh rate of 60 Hz instead of 120 Hz for rivals.

Before the start of the test, the brightness and volume of smartphones were calibrated to the same level and a robotic simulation of everyday use was launched. The type of activity changed every hour (except for the standby mode, which lasted 16 hours). Here is how much the smartphones were discharged during these tests:

After the music test, OnePlus had only 1% of the charge left, with smartphones ahead of the most severe test - filming and publishing a video on Snapchat. The OnePlus 9 Pro survived a full 17 minutes, the Galaxy S21 Ultra lasted 31 minutes, while The iPhone was able not only to survive this hour, but also to withstand another 21 minutes of the test with switching between applications.

As a result, the iPhone 12 Pro Max lasted 26 hours and 20 minutes, the Galaxy S21 Ultra - 25 hours 28 minutes, and the OnePlus 9 Pro - 25 hours 15 minutes, taking into account 16 hours of standby time.
