If you own an Apple Watch you’re probably already familiar with the relatively slow process of updating watchOS on an Apple Watch. Some simple updates may install in a reasonable amount of time, but some of the larger watchOS updates can take an hour or much more. As a result, many Apple Watch owners will either postpone software updates indefinitely or install software updates to watchOS overnight, or when they know they won’t need their watch anytime soon.
But there’s another option, and you can actually speed up the watchOS software update process quite a bit by using a little trick.
This is a fairly simple trick, and it involves simply turning off Bluetooth on your iPhone, which in turn forces your Apple Watch to download the watchOS software update over wi-fi (remember, your iPhone is paired via Bluetooth with the Apple Watch). Here’s how it works:
How to Speed Up WatchOS Updates on Apple Watch
- Start updating watchOS as usual by going to the Apple “Watch” app on the iPhone, then to “My Watch” > Settings > General > Software Update
- Tap on “Download & Install” when a watchOS software update appears
- When you see the “time remaining…” estimate appear, return to the Home Screen of the iPhone and then open the normal “Settings” app
- Tap on “Bluetooth” and toggle the Bluetooth setting to OFF to completely disable Bluetooth on the iPhone
- Return again to the “Watch” app and a message will appear about reconnecting to the Apple Watch, tap on the “Cancel” button at that popup
- When the watchOS download finishes, tap on on “Install” in the Watch app to start the installation process over wi-fi
Essentially you’re forcing the iPhone and Apple Watch to use the speedier wi-fi connection to transfer the watchOS package between devices, rather than the much slower Bluetooth.
Note you can’t just toggle Bluetooth in the Control Center because of how the Bluetooth and Wi-Fi Control Center buttons function in modern iOS releases, which just disconnect devices rather than turning off the service – that’s why you have to go to the Settings app to turn off Bluetooth on the iPhone.
This nifty trick comes our way from iDownloadblog, so cheers to them for the helpful tip.
Let’s hope a future version of watchOS or the Apple Watch iPhone app allows users to install updates through wi-fi directly without this workaround, but until (or if ever) that happens, you can simply toggle Bluetooth off on the iPhone and you’ll find the updating process is much quicker.
