In the middle of this month, Apple released two official updates, iOS 18 and iOS 17.7, one after another.
iOS 18 has a lot of new features, while iOS 17.7 is all about bug fixes.
At the time of the handover of the old and new systems, I believe everyone is also very concerned about the battery life performance of these two versions.
So without further ado, this time we still have our old friend @iAppleBytes to bring us a battery life test of the new system.
I'm sure you're already familiar with @iAppleBytes, a blogger who focuses on testing the battery life of each iOS version.
He usually tests the maximum battery life of different models in the same scenario, and makes horizontal comparisons to give a relatively objective battery life reference.

The test process was also consistent with the usual test process, and the battery health of the tested iPhone was basically maintained above 90%.
Generally speaking, the first few days of installing a new system on an iPhone are under-optimized and this process can have an impact on battery life testing.
As a result, this time @iAppleBytes was still a few days after the system upgrade was completed, and the test officially began.
@iAppleBytes After disabling the auto-brightness setting for all iPhones, uniformly adjust the brightness to 25 percent.
Finally, connect the same WiFi and test the overall battery life with GeekBench 4.
The protagonists of this test are still 6 models, namely iPhone 15, iPhone 13, iPhone 12, iPhone 11, iPhone XR and iPhone SE 2.

It should be noted that in the autonomy test of the official version of iOS 18, the @iAppleBytes did not include the iPhone SE2 model.
The final endurance test results are shown in the graph below.
It can be seen that compared with the iOS 17.6.1 version, the battery life performance of the above iPhones is not much different when running iOS 17.7, and it is basically in a stable state.
When comparing iOS 17.7 and iOS 18, the battery life of the new device is weaker than that of the old model.
Especially for the iPhone XR and iPhone 12 models, the battery life has been improved after upgrading to iOS 18.
It seems that iOS 18 has done a good job of optimizing the power consumption of older models.
It's important to note that this test simulates the iPhone's extreme battery life in heavy use.
The specific battery life performance is still based on your actual usage habits, and the data is for reference only.
At present, iOS 17.7 is basically the final version of iOS 17, and the overall performance of the system in terms of stability is very mature.
After all, iOS 18.0 is an early version of the new system, and there is still more room for optimization in the future.
In short, you can choose the version of the system you want to upgrade according to your own needs.
In addition to the battery life test of iOS 17.7 and iOS 18, a hidden change based on the real-time activity feature was also exposed some time ago.
Introducing iOS 16, Live Events is designed to show users the background real-time progress of an app through the Dynamic Island or Notifications interface.
For some fitness enthusiasts, it's also often used to keep track of workout time.
@Nico, a user of the X platform, recently said that the refresh rate of the real-time activity feature that was originally refreshed once per second on iOS 17 seems to have been slowed down to around 5 seconds to 15 seconds in iOS 18.

Subsequently, Apple officially responded to the issue in a feedback log.
According to Apple, the previous iOS 17 real-time activity process refreshed every second was a bug, which caused unnecessary battery drain on the iPhone and caused wear and tear on the device's storage.
Currently, the issue has been fixed in iOS 18.
Of course, for clock-like app processes, you can still keep track of the latest progress through real-time activities without causing abnormal power consumption.
That's all there has been to Apple's latest software developments.
Do you think the new system is power-saving? Welcome to leave a message in the comment area and discuss with you.
