New MacBook Pro - Frequent Disconnect of Magic Mouse 1

Hello,

I recently switched from a MacBook Pro Mid 2015 to the 2018 model (for cpu speed and more memory) and I am using my old magic mouse V1.

In the past, I experienced the common battery connection issues when setting down the mouse too hard.

But now, I see very frequent disconnects of the mouse even when the mouse is not moved/in hand and also sometimes the cursor gets stuck and only will move a few pixel. The first problem is resolved by clicking once and the latter only by switching the mouse off and on. Very frequent means, it happened twice while typing this *g*.

Since both old and new MacbBook are using the same version of High Sierra, I assume this is related to the new hardware. Are there any known issues with the new MacBook Pros?

One difference though: the new Mac is only connected via WLAN while the old one was using ethernet.

Any help is appreciated. This is really annoying.

Andreas

P.S. tried to reset bluetooth already. No change.
