In Apple Watch S4 Apple needs to create a brand new ASICS chipset that allows for Bluetooth 5, faster 802.11 AC (if not already in S3) and faster installation for WatchOS. Right now it seems that the iPhone downloads the package and then feeds it over Bluetooth to the Watch then installation begins. Why not use the iPhone as a conduit for management ... have the Watch download and install it - if storage allows for it. I still have 4GB free space on my (second owned) Nike+ S2.
Oooo your S3 is only now "beginning to slow down"?
Try those of us that have the Nike+ S2 that after WatchOS 3.2.3 deployed on July 19TH began to discover hiccups in Blueooth Headset connectivity reliability. Then even worse, with WatchOS 4 deployed on September 19TH 2017 (Less than 30 days before WatchOS 4.0.1 for S3) that performance CRAWLED to a baby's pace!!
S2 device performance since WatchOS 4:
Silent Mode
Storage Available: 3.6GB
Songs: 45
Photos: 13

Handoff Enabled

* I never take my watch to the gym with 40% or lower battery life.

Whenever I'm at the gym (not always is the gym's WiFi working, staff screwing around) I have 1 of my playlists playing during my weight training workout,
Jabra Sport Pulse is what I'm listening to my playlist on as well as it's heart rate monitor, and the Strong work out application. All are up to date.
IF I switch from my Strong workout to my playlist to switch a track more than the direct Next/Previous or to switch my playlist ... 8 second delay. Switching back to my Strong workout app ... 10 second delay. Worse is it seems like my watch freezes no ivsual feedback on weather or not an action is being processed during those delays. Music keeps playing.
I don't know if this is related to the iPhone 7 I have because it has it's own annoyance since I bought it summer 2017.
iPhone 7 + Jabra Sport Pulse / + Nike+ S2 : Both on silent (or just the iPhone on days I leave the watch at home) ... while listening to music there is a half second pause here and there ... seemingly randomly.
No iMessage/SMS/MMS
No Email (sometimes)
No Instagram alert/message/update on feed
I don't have a FB account not signed in from before I killed it.
I don't use SnapChat
BBM is pretty much bunk - 1 contact left and she's off completely; guess I should kill this.
So why is there seemingly an alert that is interrupting my music if it's not the headphones built in audio (I don't use the fitness coach app imbedded in the headset), Watch and iPhone are in Silent and the VIPs are not messaging or calling me so this is a COMPLETE Annnoying Mystery to me. Arrrgh.
