iOS 15.6 official version battery life test is out, it consumes more power

Last week, Apple pushed the official version of iOS 15.6 system update, which mainly fixes bugs and optimizes the system, and does not bring any new features. However, many friends who plan to stay on iOS 15 for retirement plan to choose iOS 15.6. After a few days of testing feedback from users, they found that the overall experience of this version is not bad.

As for the battery life issue that everyone is most concerned about, foreign blogger @iAppleBytes recently used the GeekBench battery testing tool to test the battery life of the official version of iOS15.6. Let's take a look at the battery life of iOS 15.6.

The models involved in the test include 9 devices including iPhone 13, 12, 11, XR, 8, 7, 6S, SE, SE 2. The testing method is to set the settings, screen brightness and other parameters of these mobile phones to be consistent with the previous system testing, and use the GeekBench application to continuously run the battery life test until the battery is exhausted.

Judging from the test results, many iPhone devices failed miserably after upgrading to iOS 15.6, resulting in decreased battery life. Only the iPhone 12 became more power-efficient after the upgrade, with an extra 30 minutes of battery life.

After upgrading to iOS 15.6, the battery life of iPhone 13 is significantly worse than that of iOS 15.5, almost 36 minutes less. This may be because Apple has made a lot of patches to iOS 15 system errors and optimized the system, which has some impact on the system operation.

Among them, the iPhone SE ran out of battery first and shut down after 2 hours and 37 minutes. After all, the first-generation iPhone SE is the smallest in size and has the smallest battery capacity among all 9 models, with only 1624mAh.

As the latest iPhone 13 and the previous iPhone 12, these two iPhones have the longest battery life. The iPhone 12 lasted for 6 hours and 18 minutes before shutting down, while the iPhone 13 lasted nearly an hour and a half longer, until it shut down at 7 hours and 52 minutes, nearly 8 hours. The battery capacities of these two iPhone 12 and iPhone 13 are 2815 mAh and 3227 mAh respectively.

Through the iOS 15.6 battery life test report, it can be confirmed that Apple has not optimized the iPhone battery. Instead, it has caused a slight decline in the battery life of many iPhone models, which is generally not serious. Only the iPhone 13 series is recommended to stay on iOS 15.5 for better battery life performance, while the iPhone 12 is strongly recommended to upgrade to iOS 15.6.

If you find that your iPhone consumes more power and gets hotter after upgrading to iOS 15.6, there are three main reasons:

1. After iOS is upgraded, it will create file index data in the background within 48 hours, which will cause the iPhone device to consume power and become hot;

2. Errors caused by upgrading the iOS system via OTA;

3. Caused by battery aging.

Friends who have already upgraded to the official version of iOS 15.6 can also share their experience after the upgrade in the comment section.

Of course, the GeekBench battery test is different from our normal usage scenarios, and the test results can only be used as a reference. Everyone should refer to the actual usage. However, compared with the test results of previous versions under the same conditions, the official version of iOS 15.6 is indeed worse.

Friends who have already upgraded to the official version of iOS 15.6 can also share their experience after the upgrade in the comment section.

In the future, Apple will focus on the iOS 16 system. iOS 15.6 may be the last major version update, but it is also possible to launch a repaired version iOS15.6.X or iOS15.7 in the future. The official version of iOS 16 will be launched together with the new iPhone 14 series.
