How big is the difference between iOS 15.4.1 and iOS 15.6? Is it worth upgrading?

On July 21, Apple officially released the official version of iOS15.6. Many friends have upgraded and found it easy to use. Some users are still using iOS15.4.1. So, taking iPhone13 as an example, which one is better, iOS15.4.1 or iOS15.6? How big is the gap between the two?

1. Battery life

When using iOS15.4.1, iPhone13 consumes 2% of power in 5 hours of standby at night. However, iOS15.6 consumes 1% of power in 5 hours of attack at night. In a 1-hour game test, iOS15.4.1 consumes 20% of power, while iOS15.6 consumes 17%. When the iPhone13 is fully charged at 7 am on iOS15.4.1 and the remaining power is 58% at 5 pm, the remaining power in iOS15.6 is 63% in the same scenario. It can be seen from the actual test that the official version of iOS15.6 has better battery life.

2. Signal

The signal performance of iPhone13 on iOS15.4.1 is 1 bar of signal in high-rise residential buildings, 2 bars of signal in business districts, and full bars of signal in outdoor scenes. The signal performance of iOS15.6 is 1 bar of signal in high-rise residential buildings, 2-3 bars of signal in business districts, and full bars of signal in outdoor scenes. In terms of signal, iOS15.6 is slightly better.

3. Fluency

The fluency of iPhone13 on iOS15.4.1 is pretty good, with no lag or frame drops during daily scrolling. The fluency of iOS15.6 is also perfect, except that when compared to the speed of opening APP, iOS15.6 is slightly faster.

4. Fever

When iPhone 13 is used lightly in daily outdoor scenes with iOS 15.4.1, the heat is more obvious. When it is used almost without heat indoors, the heat on the back of the phone is more obvious when playing games indoors. When it is used lightly in daily outdoor scenes with iOS 15.6, the heat is slightly lower than before. The heat on the back of the phone when playing games indoors is also significantly reduced.

5. Kill the background

iPhone13 often has the phenomenon of killing background processes in iOS15.4.1. I personally think that the phenomenon of killing background processes in the new phone should be due to system optimization. Upgrading to iOS15.6 perfectly solves the problem. After using it for a week, there has been no background killing phenomenon.

It is not difficult to see from the above tests that the official version of iOS15.6 has certain improvements in the above five aspects compared to iOS15.4.1. Although the improvement seems not significant, it is actually more comfortable to use.

I believe everyone already knows the difference between iOS15.4.1 and iOS15.6. If you think the current system is stable, you can choose not to upgrade. If you are not satisfied with the current system, you can consider upgrading.
