Adoption of iOS 26 has hit the halfway mark, but a significant number of iPhone users are still holding back, citing concerns about battery life, performance, and the controversial 'Liquid Glass' design. As the Mobile & Apps Editor here at Automatica Press, I've seen this hesitation before, but this year seems particularly pronounced. Is Apple's push for the latest and greatest leaving some users behind?

Battery Life and Performance Fears Stall Updates

New data from SellCell paints a concerning picture. Their survey of 2,000 U.S. iPhone users reveals that nearly a quarter (24.2%) are worried iOS 26 will drain their battery faster. I've personally experienced this with past updates, and it's a legitimate fear. Nobody wants their phone dying before lunchtime. Another 23.8% are concerned about overall performance degradation. Older devices, in particular, can struggle with the demands of a new OS.

It's not just about technical performance, though. A substantial 17.5% of those surveyed expressed dislike for the new 'Liquid Glass' design. Some find it harder to read, while 8.6% are frustrated that certain visual elements can't be disabled. I've heard similar complaints from readers: change for the sake of change isn't always progress. Apple's commitment to accessibility needs to be front and center.

Delayed Updates and Lingering Distrust

SellCell also found that only 38.8% of users update immediately when prompted. The majority, a whopping 61.2%, delay or defer updates. This includes waiting to see if others report problems, assuming updates happen automatically (they don't, folks!), dismissing reminders, or simply postponing for weeks or months. I always advise a cautious approach – let the early adopters find the bugs first. Some folks won't update until an app stops working, which is a risky game, but understandable.

Adding to the complexity, Apple just released iOS 26.2.1 this week, but 9to5Mac reports that iOS 26.3 is expected to launch soon. This next update will introduce three new ways to customize iPhones with additional settings and wallpaper options. That may sway some fence-sitters, but the underlying performance and design concerns need to be addressed.

"Apple needs to reassure users that updating to iOS 26 won't turn their beloved iPhones into battery-guzzling, lag-filled bricks."

Ultimately, Apple needs to reassure users that updating to iOS 26 won't turn their beloved iPhones into battery-guzzling, lag-filled bricks. Transparency about performance impacts on older devices and greater customization options could go a long way. Until then, I suspect adoption rates will remain stubbornly below Apple's expectations, even with customization options coming in 26.3.
