iOS17.2.1 upgrade experience, battery life test, except for this one have dropped

After the new version of the iOS system is pushed to upgrade and update, many iPhone users are more concerned about the performance of the new version of the iOS system in terms of battery life, and whether it is worth upgrading.

Apple pushed the iOS17.2.1 official version upgrade update to the iPhone last week, which is a minor version of the upgrade update, the update package size is only 207MB, and the iOS17.2.1 official version upgrade update contains important bug fixes, and solves the problem that the battery drains faster than expected in some cases, and it is recommended that all users upgrade and install.

Foreign bloggers @iAppleBytes also tested the battery life of the official version of iOS17.2.1, and @iAppleBytes tested the battery life of iPhoneSE2, iPhoneXR, iPhone11, iPhone12 and iPhone13 after upgrading to iOS17.2.1 official version.

@iAppleBytes set the brightness of the 5 iPhones to 25%, connect them to the same WiFi, and then test the overall battery life with GeekBench 4

The test results show that after upgrading to iOS17.2.1 official version, in addition to the improvement of the battery life of the iPhone11, the battery life of the other four iPhones has decreased a little, of course, not by much.

In general, the official version of iOS17.2.1 upgrade is relatively stable in battery life.
