Apple Watch suddenly VERY slow
I've been using my Apple watch for a month now, everything was running smoothly.
Then, yesterday it became VERY slow. Some apps just didn't charge at all, some charged very slowly.
Connection got unstable. Battery drained faster then normal.
Nothing especial happened yesterday. I had already updated to WatchOS 3 more than two weeks ago. I installed yesterday a new app (Watchfy).
Already tried unpairing / repairing, rebooting (watch / Iphone), turning off / on Bluetooth, deleting some apps.
Iphone SE, IOS 10.
Has someone had the same problem? Is there a known solution?
Thanks!!
