Why many iPhone users are not updating to iOS 26

Although iOS 26 has been available since September, a significant portion of iPhone owners in the US have yet to install the update. According to a new SellCell study of 2,000 adult users, about 22% of respondents are still on previous system versions. The reasons are more varied than simply not wanting to change a familiar interface.

The most unexpected factor turned out to be a simple lack of information: many users said they simply didn't know iOS 26 had been released. Next is the common misconception that the iPhone will update automatically without the owner's involvement. Additionally, some people deliberately postpone installation due to fears that the battery will drain faster after updating.

Another notable reason is the mixed perception of the new Liquid Glass design. Some users find it less readable or just unfamiliar, so they prefer not to rush. There are also concerns that the iPhone might run slower after the update, which relates to the past experience of many Apple device owners.

The survey showed that most users generally don't like updating immediately. 61% of respondents wait some time to make sure the system doesn't contain serious bugs. There are also those who install updates only when the device starts persistently demanding it.

Interestingly, only 28% of participants said nothing bothers them about iOS 26, meaning the vast majority have at least one doubt. The main fears remain reduced battery life and performance degradation, while the Liquid Glass design has become an additional factor that could deter users from switching to the new system version.
