Every time Apple pushes a new iOS system update, many users hesitate whether to upgrade, and one of their concerns is worrying that the battery life of their iPhone will get worse after upgrading.

After all, for users who have already upgraded to iOS 26, it is currently impossible to downgrade back to iOS 18. If the battery life of the new version is better, it can at least serve as a positive signal for keeping the system updated.

Recently, foreign blogger iAppleBytes conducted a battery life test on iOS 26.2 as usual.

The old Geekbench built-in battery benchmark tool was used, with parameters such as brightness and Wi-Fi unified as much as possible during the test. The time from full charge to automatic shutdown was recorded by having the iPhone run under continuous high load.

However, the models participating in the test did not cover all iPhones, only including 7 models: iPhone 11/12/13/15/16/SE2.

The test results (Geekbench battery benchmark test, continuous time from full charge to shutdown), compared with iOS 26.1, are as follows:

From the results, the improvement of iPhone 13 is relatively obvious, while iPhone 11 and iPhone 15 have seen a relatively obvious decline, and the remaining models are basically at similar levels.

But it should be emphasized that Geekbench's battery test is essentially a continuous high-load test, which is quite different from our daily mixed usage scenarios such as watching videos, taking photos, and playing games. Moreover, a single test result is also likely to have errors. In short, this result is for reference only.

In terms of the editor's personal actual experience, according to the daily battery usage statistics of the iPhone, the battery life of iOS 26.2 is not significantly different from that of iOS 26.1, and the overall level is still normal.

In fact, minor version releases of the iOS system (such as 26.1 or 26.1.1) rarely bring surprising improvements in battery life. More often, they just maintain the status quo, and the perception will not be obvious. Instead, we need to be alert to abnormal heating, sudden surge in power consumption and other situations, but fortunately, there has been no large-scale feedback on such problems in the current iOS 26 system.

Finally, we also conduct a small survey. Friends who have upgraded to iOS 26.2 can score the battery life and smoothness for more users' reference.
