Apple has unexpectedly released a revised version of the iOS 26 Developer Beta aimed at addressing a significant battery issue. This update comes shortly after the initial Developer Beta was made available for iPhone 15 and iPhone 16 users on June 9, the first day of WWDC. Although it is labeled as a Developer Beta, users do not need to be registered developers to install it, as Apple has removed the $99 fee previously associated with becoming a developer.
The reason behind this rapid deployment of a revised Developer Beta is due to a critical bug present in the first release. Users reported that the low battery symbol could erroneously appear on their screens, which might leave their devices unable to turn on after installation. This update seeks to rectify this issue, preventing the possibility of bricking an iPhone 15 or iPhone 16.
Importantly, devices from the iPhone 11 series to the iPhone 14 series are not affected by this battery problem, while older models are incompatible with the new update. The Developer Beta serves as a testing platform for app developers, allowing them to ensure their applications function properly with the new operating system. Apple is set to launch the first public beta of iOS 26 in July, with a full stable release scheduled for September, coinciding with the introduction of the upcoming iPhone 17 series, which includes the new ultra-thin iPhone 17 Air.
A standout feature of the iOS 26 Developer Beta 1 is its innovative Liquid Glass design. This feature presents a translucent appearance with real-time light refraction, contributing to a modern and cohesive look. For those interested in installing the revised beta, registered users can navigate to Settings > General > Software Update to proceed with the installation, ensuring their devices are backed up beforehand.
