Sometimes Apple Magic Mouse 2 (which I bought from Aliexpress) connects to the computer only after a short time (2-5secs) recharging even if its own charge level is big.
I do not have a link to this product in Aliexpress right now, because this store (Global Tops-E Online Store - https://www.aliexpress.com/store/5068440) does not sell this, full of bugs, "Apple" Mouse now.
Also, I do not recommend buying anything from this seller (Global Tops-E Online Store), because they are swindlers. Actually, I have lost $80 buying this mouse. Be careful!
