Google implements pulse loss detection for users of the Pixel Watch 3.

      Google has started rolling out its Loss of Pulse Detection feature to Pixel Watch 3 users in the United States. This potentially life-saving capability utilizes the watch’s optical heart rate sensors to determine if the wearer’s pulse stops at any time, which could indicate situations like cardiac arrest or other heart-related issues. If such problems are detected and the wearer becomes unresponsive, the watch can automatically notify emergency services. The rollout is gradual, and all users are expected to have access to it within the next few weeks.

      The feature was initially announced alongside the Pixel Watch 3 in August 2024 and was already available in several European countries. However, its launch in the U.S. required approval from the Food and Drug Administration (FDA), which was granted in late February 2025. As it becomes available to both new and existing Pixel Watch 3 owners, it could be a worthwhile time to consider purchasing one if you're looking for a smartwatch alternative.

      To ensure the feature's reliability and reduce false alarms, Google dedicated significant time to rigorous testing, analyzing over 100,000 hours of data to refine its performance. The company also published a peer-reviewed study in Nature that outlines its long-term development and effectiveness.

      Users will receive a notification on their Pixel Watch 3 prompting them to enroll in the Loss of Pulse Detection feature. Once activated, the watch will continuously monitor the wearer’s heart rate and will initiate emergency protocols if a pulse loss is identified and the wearer fails to respond after a certain period.

      For those interested in acquiring the Pixel Watch 3 with this advanced health monitoring feature, both new and existing devices will be eligible for the update. This could be particularly beneficial for individuals who may have undiagnosed heart issues, but it is generally a valuable feature to have.

      Does the Google Pixel 9a feature a 120Hz screen?

      The Google Pixel 9a is a mid-range device that offers impressive value without significant compromises. The phone has undergone various enhancements, including the removal of the camera bump, the addition of a new processor, and an increased screen size, all while maintaining the same price point. With the recent launch of Apple’s "midrange" device, the Apple iPhone 16e, comparisons between the two are inevitable. The Google Pixel 9a is a more budget-friendly option and outperforms the iPhone 16e in several areas.

      Does the Google Pixel 9a have a 120Hz screen?

      Yes, the Pixel 9a supports refresh rates ranging from 60 to 120Hz. It features a screen resolution of 1080 x 2424 pixels, with over 422 pixels per inch (PPI) and a 20:9 aspect ratio. The display can achieve a peak brightness of 2,700 nits, allowing for comfortable use even in direct sunlight, and can reach up to 1,800 nits with HDR enabled.

      Is the Google Pixel 9a waterproof?

      The Google Pixel 9a, the latest addition to Google's affordable Pixel smartphone lineup, introduces several upgrades at a competitive price. This model boasts a vivid pOLED Actua display and Google's Face Unlock technology, along with traditional fingerprint security. The phone is available in four matte colors: Obsidian, Porcelain, Iris, and Peony, and features slightly thicker bezels than Google's premium models. Equipped with a Google Tensor G4 processor and 8GB of RAM, it is designed to handle demanding tasks.

      However, an important consideration for some users is its resistance to elements. Can it withstand exposure to water and everyday splashes? Google's premium Pixel models are recognized for their excellent water and dust protection, so it's reasonable to question the resilience of this more budget-friendly model. Therefore, is the Google Pixel 9a safe to use around water?

      Does the Google Pixel 9a come with a charger? Here’s what’s in the box.

      After much anticipation, the Google Pixel 9a has officially been announced. Google's Pixel A series is a great option for those looking for a dependable Android smartphone at a lower price, and the latest model continues this tradition. While it is undoubtedly part of the Google Pixel 9 series, it features fewer capabilities than its high-end counterparts.

      One query that potential buyers may have regarding the Pixel 9a is whether it includes a charger. Here’s the answer:

      The Pixel 9a does not come bundled with a charger. This has become standard for most smartphones these days, including other models in the Pixel 9 series, such as the Pixel 9 Pro. While this may be disappointing for some, it is not unexpected.
