Choose to upgrade to iOS 26.2 or stay with iOS 18.7.3, just want to keep the two words peace

Apple just released iOS 26.2 and iOS 18.7.3 at the same time, so which version is reasonable to upgrade?

In essence, iOS 26.2 and iOS 18.7.3 were born with different purposes and are aimed at different iPhone audiences. iOS 26.2 brings smoother performance, fixes many important bugs on iOS 26.1, improves battery life as well as addresses negative user feedback about the Liquid Glass interface. Meanwhile, iOS 18.7.3 is more aimed at older iPhone models, still ensuring the performance inherent in iOS 18 but still providing a serious security patch, limiting the risk of being ‘visited’ by hackers due to vulnerabilities that can be exploited.

Choose iOS 26.2 or iOS 18.7.3?

In fact, if users have updated to iOS 26.2, they can fix the vulnerabilities that have been patched on iOS 18.7.3. However, iOS 26.2 will be more suitable for the new generation iPhone lines, equipped with a more powerful processor chip, with better graphics processing capabilities to be able to ‘carry out’ new effects on the Liquid Glass interface.

Meanwhile, iOS 18.7.3 was created for devices with old hardware and limited battery performance. At this time, the device needs a more stable and gentle operating system than the new transparency effects on iOS 26. The interface on iOS 18.7.3 remains unchanged compared to the iOS 18 version, with no new icons, no additional features or other fancy effects.

Overall, iOS 18.7.3 is an important security update that needs upgrading but does not affect the performance or battery life of the device.

Thereby, you can also choose for yourself the necessary operating system version to upgrade your iPhone device. Personally, the models that should upgrade to iOS 26.2 should only be iPhone 13 Series or higher, the rest should choose to stay on iOS 18.7.3 to get the best performance.
