With its expected debut just two months away in September 2026, rumors about the Apple Watch Series 12 are becoming more detailed. Based on internal code leaks and insights from prominent leakers, the next-generation smartwatch from Apple will bring concrete improvements, starting with a new processor and extended battery life. There are also whispers about less certain features like Touch ID on the side button and health sensors in the band, but these remain speculative.
A new chip after a one-year pause
The current lineup (Apple Watch Series 11, Ultra 3, and SE 3) all share the same S10 chip from the previous year. Now, leaked Apple code indicates that the Series 12 will receive an upgraded processor, likely called S11 or S12. After a year without performance gains, users can expect a tangible boost in speed and efficiency. The new chip is expected to enhance watchOS 12, providing smoother app launches and more responsive complications.

Longer battery life on the way
A well-known leaker on the Chinese social platform Weibo revealed that Apple is focusing on improving battery life for the Series 12. Currently, the Series 11 offers up to 24 hours of normal use and 38 hours in Low Power Mode. With the new model, Apple aims to exceed these numbers, possibly approaching two days of typical usage. This would be a significant step forward for users who prefer not to charge their watch nightly.
Touch ID on the side button: possible but uncertain
References to Touch ID have appeared in Apple code snippets, suggesting that a fingerprint sensor might be built into the side button. This would allow users to unlock the watch without entering a passcode, enhancing convenience and privacy. However, one leaker denied this rumor, and authoritative sources like Bloomberg's Mark Gurman and supply chain analyst Ming-Chi Kuo have never mentioned Touch ID for the Apple Watch. For now, Touch ID remains a long shot.

Band sensors: a futuristic idea
Another rumor from leaker Kosutami claims that the Series 12 will feature a band with at least one health sensor, a first for Apple. This could enable new measurements like skin temperature or hydration, but the lack of credible support makes this rumor highly speculative. Apple has always integrated sensors directly into the watch for accuracy and reliability.
As we await the official September 2026 launch, the Apple Watch Series 12 appears to offer promising updates. The new chip and longer battery are nearly certain upgrades, while Touch ID and band sensors hang in the balance. For those concerned about data security, it's worth noting that privacy protection remains a hot topic: recently, the ACLU launched a legal toolkit to expose police surveillance technologies, an initiative that underscores the importance of transparency in wearable devices.
