Apple Watch Series 2 running slower on OS 4.0

Has anyone else noticed how slowly Apple Watch Series 2 running slower on OS 4.0 now runs Siri for calling or starting an exercise app. It's so slow now I might as well go back to Fitbit! Only had my Apple Watch 2 for 3 months so a little ****** off to say the least. It seems like they do this every time when they do an update with new equipment coming out they make the old version slower intentionally. There little point in using the Siri call function now as it's quicker to get your phone out of your pocket unlock it, select the phone app and call your self. Barking mad!!! Apple Pay now never works the first time and ask me to try again later, press it again and it works!

I know I’m a bit late to this thread but I found a solution that has worked for me. My watch has been horribly slow since watchOS4, especially when using the Workout App. I was playing with the settings today and stumbled across ”Detect Gym Equipment“ being on. I never venture into a gym so turned it off and what do you know, the watch is responsive again!


From the watch... Settings > General > Workout > Detect Gym Equipment > turn off


Hope it helps.

Same issues. I’ve gone through the reset/repair cycle many times and no improvement on my series 1. Starting workouts is just simply a painful process. If lucky, it hangs for a while (>20s) or outright crashes. I’ve intentionally not loaded additional apps on there to try to improve things but it’s borderline becoming useless as a fitness tracker. I’m so disappointed. Because of the recent trust issue, I can’t help feel this is similar to the recent battery-gate. It’s not convincing me to update at all, but rather jump-ship to Fitbit....

Yes, both my and my wife's Series 2 watches, just a few months old when upgraded to watchOS 4, now seem like they are a few years old—glacially slow launching apps, changing faces, etc. The Siri feature is unusable. I've been using Apple products for more than 30 years and while this is a familiar problem with their products, this is the most egregious example I have seen in several years. I was hoping for improvement with the point updates, but we've had two of them now without any restoration of performance. I'm a very disappointed customer at this point.

I have the same issue. The Nike app is so abysmally slow that it barely starts and the voice guided features and such lag and don’t work. I totally wiped my iphone7 and series 2 Apple Watch and reinstalled everything: no change.


This is completely unacceptable and I wonder if they have clocked down the old watches similar to the phones. WatchOS 4 has totally ruined this for me. My ecosystem is all Apple, Macs, Apple TV. Now I’ll be replacing this watch with a Garmin and seriously considering moving away from the ecosystem in general.
