Every time the iPhone is upgraded, it's a big concern, especially in terms of battery life. After the official version of iOS18 was launched, many friends wanted to know how big a gap there is between it and iOS17 in terms of battery life. Today we will talk about this controversial topic.
Test process:
We found two identical iPhones15, with iOS17 and iOS18 system versions, and the battery health was 100%. First of all, I played 1 hour of 4K video streaming, and there was not much difference in consumption between the two phones, but iOS18 had a slight lead. This is followed by a comparison of 1 hour of gaming battery life, which is basically a high-intensity test and a heavy power consumption link. During the test, we found that using wireless networks for testing today is expected to be more power-efficient than connecting to 4G and 5G, and of course the reference value is still relatively high.
Then, we also compared the autonomy of the 1-hour shooting, and scored in between. This part of running is very power-hungry because it will mobilize a large number of functions and images. After two benchmark software, we found that the temperature of the iPhone15 of iOS17 reached 44° degrees, while the temperature of the iPhone15 of iOS18 was around 42° degrees, and the temperature of iOS18 was better in terms of temperature control, and the battery life was also about 3% ahead.
Test Results:
In the end, the iPhone 15 with iOS17 lasted six hours and ten minutes, which is a decent result, and it could be worse if it was in the case of 4G or 5G. And the iPhone 15 with iOS18 lasted for six hours and twenty-eight minutes, which is indeed a bit better.
Summary:
What do you think about the battery life of the iPhone 15 after upgrading to iOS18? Do you think the improvement of iOS18 is obvious, or do you think that iOS17 is enough for the needs? Feel free to leave a message in the comment area to share your views.
