Testing iOS 14.4 battery life on iPhone 11, iPhone Xr, ...

Although not mentioned in the description of the update, many people are also very concerned about the battery performance of this version.

Not to let you wait long,  YouTuber iAppleBytes  recently performed battery tests on 7 iPhone models, including:  iPhone SE,  iPhone 6s ,  iPhone 7 ,  iPhone 8 ,  iPhone 11  and  iPhone SE (2020) , shows that the latest iOS 14.4 update does bring some battery performance improvements.

Specifically, when running iOS 14.4, iPhone 11 lasted 5 hours and 33 minutes in the test on Geekbench. Compared to iOS 14.3 (with a duration of 5 hours and 7 minutes), the device has improved to 26 minutes of use.

Similarly, the iPhone 8 used about 3 hours 47 minutes in the test, up 15 minutes from iOS 14.3. The iPhone 7 also has a significantly increased battery life of about 15 minutes, while the iPhone SE (2020) adds a few minutes.

Although I have not tested with the iPhone 12 series  , when looking at the results of the tests on previous devices, we can confirm that iOS 14.4 has significantly improved the battery life of the iPhone. .

Have you updated iOS 14.4 for your iPhone and how do you feel?
