Apple Watch Ultra users are eagerly anticipating the announcement of the successor to their device, just a month away. However, the recent watchOS 9.6.1 update appears to have introduced unexpected problems, notably severe battery drain issues.

Following the installation of watchOS 9.6, many Apple Watch Ultra users have been voicing their concerns about rapid battery depletion. The update was intended to fix UI bugs, but unfortunately, it seems to have brought about more problems than solutions for these users. Interestingly, this update didn’t introduce any noteworthy new features; the previous version, watchOS 9.5, merely included the Pride Watch Face alongside rainbow watch straps.

While watchOS 9.5 and 9.6 did bring some undisclosed security patches and bug fixes, the lack of detailed changelogs has left users in the dark. For instance, watchOS 9.6 included critical security patches addressing issues such as arbitrary code execution with kernel privileges and unauthorized access to sensitive location information via Find My.

The latest version of the OS for watch, WatchOS 9 was rolled out by Apple on 15th August. It is compatible to run on the Apple Watch Series 4 and the latest Apple Watch Ultra models.

The watchOS 9.6.1 battery drain issue has become a focal point, impacting users’ daily experiences. Even with battery health at a healthy 99%, users have reported that their Apple Watch Ultra now barely lasts a day and a half, often dropping to around 65% within 8 hours.

This battery issue doesn’t seem to be limited to older units; even recently purchased Apple Watch Ultras are encountering the same watchOS 9.6.1 battery drain problem. The scale of the problem is apparent from the numerous reports, leaving users justifiably frustrated with this flagship smartwatch’s performance.

Regrettably, Apple Diagnostics has been unable to pinpoint the source of the issue, exacerbating concerns. With battery life diminishing to less than a day for some users, the seriousness of the problem is evident. It’s crucial that Apple promptly addresses this battery drain problem, especially given the recent changes to memory management and kernels introduced by the security updates.

Despite the potential security benefits, users are advised to exercise caution before updating to watchOS 9.6.1 Since this update doesn’t bring any significant new features, those content with their current version’s stability might want to refrain from updating. A potential solution, although not without its own challenges, is to consider updating to the watchOS 10 Beta, available through the Apple developer program. However, this path isn’t recommended unless users are familiar with the potential complications that beta software can entail.

In summary, the battery drain issue following the watchOS 9.6.1 update has created significant disruptions for Apple Watch Ultra users. While the update did address critical security vulnerabilities, it’s clear that the associated changes have inadvertently impacted battery performance. Users are left hoping for a forthcoming solution from Apple, whether through a subsequent patch or update. In the meantime, users will need to carefully consider their options and the potential trade-offs involved in finding temporary workarounds for this issue.

Let’s check out the mixed responses from people who have updated their Apple Watches with the latest watchOS 9.6.1!

What is the watchOS 9.6.1 Battery Drain issue?

However, numerous users have reported that their Apple Watch Ultra’s battery life has significantly decreased since installing the patch.

According to these reports, the Apple Watch Ultra used to maintain a battery life of at least 2 to 2.5 days on a single charge, and sometimes even up to 3 days with moderate usage. The current situation is undeniably concerning. Users have expressed that despite fully charging their smartwatches overnight, the battery level drops to 67% within just eight hours—even shortly after putting the watch on their wrist. Remarkably, the battery’s health remains unaffected by these issues.

Curiously, even those who have recently purchased the watch and updated the firmware are encountering the same troubling battery performance.

Users have reached out to Apple’s support for assistance, but even after conducting hardware diagnostics, the issue remains unidentified. Some users have expressed their frustrations in forums. For instance, one user questioned if others were observing a significant reduction in battery life over the past couple of days. Their Apple Watch Ultra, just a month old, previously lasted 2-2.5 days on a single charge but now barely manages a day. Notably, this change occurred without any alterations to settings or usage behavior.

Another user shared their experience, mentioning that their watch’s battery dropped to 6% within only 23 hours of usage. This occurred despite engaging in a 3-hour run with 1 hour of podcast streaming. Even though battery health still indicates 100%, such issues have left users less than satisfied.

In an attempt to resolve the problem, users have followed common troubleshooting procedures like restarting, unpairing, repairing, and even performing factory resets on their watches. Unfortunately, none of these steps have yielded any positive results.
