Apple has launched the second public beta version of iOS 26, introducing a range of innovative features such as the Liquid Glass interface and live translation capabilities, all set to debut next month alongside the much-anticipated iPhone 17 announcement. While the urge to install this update may be strong, it’s essential to approach it with a sense of caution and realistic expectations. Pre-release software is inherently incomplete, and although a public beta indicates a level of confidence from Apple, the primary objective is to assess its performance before a wider rollout to millions of devices. Despite the relative stability of the iOS 26 developer beta, unforeseen bugs could still emerge.

The Stability of the Public Beta
One notable aspect of the iOS 26 public beta is its increased stability compared to the developer versions, which are primarily designed for developers needing to push the limits of stability to test their applications. However, “more stable” does not equate to “completely reliable.” Apple continues to refine features within the iOS 26 betas leading up to the expected September or October launch. If you choose to explore the iOS 26 public beta, it is advisable to do so on a secondary iPhone rather than your primary device. The beta is compatible with models dating back to the iPhone 11, so consider using an older device from your collection. Additionally, ensure that you have comprehensive backups of your important data before proceeding.
Potential Bugs in the iOS 26 Public Beta
Now, let’s examine why opting for the iOS public beta might not be the best choice for everyone. Software bugs during the development phase are an anticipated reality—this is precisely the purpose of beta testing. This phase allows developers to identify and address potential issues before the final product is released. Expanding the public beta to a broader audience helps uncover unique interactions among various iPhone models and third-party applications. Bugs can manifest in numerous ways, including connectivity problems with Bluetooth or Wi-Fi and occasional crashes of third-party apps. Additionally, excessive background processes may lead to increased device temperature, which can adversely affect battery life. While I have not encountered any catastrophic bugs during beta testing—typically, the issues are minor annoyances—these occurrences are standard in developer and public beta versions. If you prefer to avoid potential bugs and usability issues, it may be wise to refrain from installing the iOS 26 public beta on your main device.
Impact on Battery Life
If you’ve recently purchased a portable charger for your iPhone, be prepared to rely on it more frequently while running beta software. Optimizing energy efficiency tends to be a lower priority for Apple’s developers during the beta phase, as their focus is on ensuring feature functionality and resolving bugs. An iOS update initiates a series of internal indexing processes that can consume significant energy for several hours or even days post-installation. For instance, the Photos app will refresh its database of recognized individuals, scan images for new identifiable objects or scenes, and search for duplicates. Consequently, running beta versions can be taxing on battery performance.
Performance May Be Affected
Due in part to the extensive reindexing of data stored on your device, the iOS 26 public beta is unlikely to deliver the performance levels you might expect. Applications and games that require substantial processing power will need to be calibrated to function effectively with the new iOS, which may result in noticeable stuttering or glitches. While Game Mode is designed to enhance performance in demanding gaming scenarios, beta software can disrupt these low-level processes. I understand the temptation to dive into new features as soon as they are available, but it’s wise to exercise patience to avoid potential pitfalls that can arise from beta testing.
