If you were hoping for more exciting updates with the Apple Watch Series 8, you might have to temper your expectations. It was thought that the next-generation watch would have a body temperature sensor, but it may not be the case.

A body temperature sensor for the Series 8 has been rumored for a long time. Mark Gurman, who has a pretty good track record when it comes to Apple rumors, said in June that a body temperature sensor was coming. The Wall Street Journal said in September that there was a possibility of a fertility feature. The body temperature sensor was predicted by the Apple analyst. There are many reasons to believe that this was in the works.

Gurman backtracked in his latest newsletter. Don't expect any of the Series 8's capabilities to be available soon, Gurman wrote. Body temperature was on the agenda, but chatter has slowed down recently. Blood pressure is at least two to three years away, and I wouldn't be surprised if it doesn't land until later in the second half of the decade.

It makes sense for blood pressure and blood sugar. There has been a lot of progress in blood pressure monitoring, but the technology is still not there. The same applies to the monitoring of blood sugar. The feature was rumored for the Series 7 but never materialized. The prototype from Japanese startup Quantum Operation was featured at the Consumer Electronics Show, but it is not ready for use in consumer-grade devices. Body temperature sensors are already available in several other consumer Wearables, including those from rivals. In 2020, researchers used body temperature sensors in Wearables to try to determine if the smartwatches could detect COVID-19.

Body temperature sensors are mostly used for sleep and recovery tracking, but fertility Wearables like Ava may also feature them. Apple has added sleep and period tracking in the past few years, but they are on the simpler side. Adding a body temperature sensor would help level up these features, especially if the company is planning on adding fertility-related features. Apple is notorious for sitting on features other device makers have already implemented until it is happy with its own version.

Gurman says that a body temperature feature isn't completely dead becausehatter slowing down doesn't mean it's dead. It brings up the idea that it is unrealistic to expect Apple to introduce a new feature every year on its watch. Since the Series 3, Apple has been ahead of the competition when it comes to advanced smartwatch capabilities. The Series 3 introduced cellular, the Series 4 changed the design and added FDA-cleared EKGs, the Series 5 added an always-on display, and the Series 6 added a SpO2 sensor. The Series 6 additions were less buzz-worthy. SpO2 sensors have been on the Series 7 for a while, but the main feature was a larger screen.

The Apple Watch is the most popular watch on the market, and Apple has been in the lead for a long time. There is a transition to a new unified platform for Wear OS watches. Both of them have advanced health features and better batteries, but they lag in smart features. Many of its health and fitness features are not as polished as the one from SAMSUNG. There is no need for Apple to dramatically change things in the short term as it is already investing in more health research.

It will take a while before consumer use of advanced health features like blood pressure and bloodglucose. They will probably have to go through the FDA clearance process when they are ready. It is more than likely that future Apple Watch updates will focus more on design, incremental hardware upgrades, and software updates that make use of existing sensors. Gurman predicted the Series 8 would have a rugged sports version and a new entry-level model. If Apple could figure out how to include multiday battery life, we would all settle down.
