Apple’s latest operating system, iOS 26, has seen slower adoption than previous updates, with around 55% of compatible iPhones currently running the new software. Some sites report higher numbers, up to 70%, but adoption still lags. The slower uptake may be due to the controversial Liquid Glass design introduced in iOS 26.
While some users have hesitated, the OS has received multiple updates that fix early bugs, improve battery life, and give users more control over the Liquid Glass aesthetic. Adjusting opacity in Settings → Display & Brightness → Liquid Glass addresses legibility concerns for many users.
The most important reason to update is security. iOS 26 includes critical security fixes that are not available on iOS 18. Delaying the update leaves devices vulnerable to threats, and Apple is not offering these patches for older versions.
Concerns about battery life are typically short-lived. The initial reindexing after installing a new iOS can temporarily drain battery, but performance normalizes within a few days.
For iPhone users hesitant about Liquid Glass or waiting for iOS 26.3, it’s worth noting that the next update may arrive later than expected. Updating now ensures you’re protected and have access to the latest features.
