It’s no secret that the Apple Watch is a convenient accessory for the iPhone, but even so, it tends to use the Bluetooth radio for most file transfers. This can sometimes be unbearably slow, especially when the transfer involves large or several files at one time.
It should be noted that the Apple Watch is Wi-Fi enabled in addition to Bluetooth-enabled, and while the Apple Watch prioritizes the Bluetooth connection over Wi-Fi, it is possible to force Wi-Fi usage for file transfers between an Apple Watch and an iPhone; but this requires effort.
iOS developer udevs wanted to improve this user experience, and so a free jailbreak tweak called NanoFi was consequently conceived. Once installed, it forces the Apple Watch to prioritize its Wi-Fi connection instead of Bluetooth for file transfers.
If you’re wondering what types of file transfers occur between the Apple Watch and the iPhone, a few different examples include Music, Photos, and even software updates. When the file sizes are large, or you transfer these files in large quantities, Wi-Fi proves to be much faster than Bluetooth every single time.
Perhaps the only caveat is that Wi-Fi needs to actually be available for your device to use it. Your Apple Watch automatically uses any Wi-Fi networks that your iPhone recognizes. If you don’t have any recognized Wi-Fi networks nearby, then you’ll need to join a Wi-Fi network or your Apple Watch will fall back to using Bluetooth until you do.
Since NanoFi works behind the scenes, it should come as no surprise that the tweak doesn’t have any options to configure. Simply installing the tweak on your jailbroken iPhone is enough to improve the file transfer performance between your Apple Watch and your iPhone — so long as Wi-Fi is available when you use it.
If you’re interested in giving NanoFi a try, then you can download the tweak for free from udevs personal repository via your favorite package manager app. The tweak supports jailbroken iOS 14 devices, and obviously, the user needs an Apple Watch to take advantage of it.
