Apple has cautioned iPhone users that the newly released iOS 26 update may temporarily impact battery life. The company included the warning in the update’s release notes and linked users to a support page that explains why this happens.
According to Apple, major system updates often trigger a spike in background activity. After installing iOS 26, iPhones may run indexing, app updates, and asset downloads in the background, which can cause devices to heat up and drain power faster than usual. The company stressed that this effect is short-lived and should normalize once these processes finish.
Beyond background tasks, Apple also pointed out that new features in iOS 26 demand more system resources, which may slightly affect performance and energy use depending on individual usage. However, the company reassured users that ongoing optimizations in future updates will smooth out these issues.
Despite the potential dip in performance, Apple emphasized the importance of updating. iOS 26 not only brings enhancements to apps like Safari, Messages, and Control Center but also includes critical security patches and bug fixes. Skipping updates could leave devices vulnerable or cut users off from the latest features, including Apple Intelligence.
Apple’s move to address the issue directly reflects a proactive approach, as complaints about battery drain after iOS updates are a recurring concern. This time, the company is attempting to manage expectations early by explaining the situation upfront.
In short, if your iPhone feels warm, sluggish, or loses battery quicker after upgrading to iOS 26, there’s no need for panic—it’s part of the adjustment process, and performance should balance out soon.
