keep losing bluetooth connection magic mouse and keyboard

Hi,

I purchased a new iMac 27

The Specks:

iMac (Retina 5K, 27-inch, Late 2015)

32 GB 1867 MHz DDR3

2T Fusion Drive

4 GHz Intel Core i7

AMD Radeon R9 M395 2048 MB

This was not at cheep setup.

The first 2-3 weeks went fine – but then I keep loosing connection to my mouse and keyboard that came included. I notes’ that the connected Bluetooth icon on the top right corner goo’s to “unplugged” and the computer tells me the mouse and keyboard are unplugged. This I not expectable for a setup on this price range!!

When I keep working non stop for an hour or 2 the problem seems to decrease – but never goo’s away!

Every time the computer goes on standby the problems coms back after 5-10 minuets

The funny thing is - it looses connection while I’m fully working or dragging sliders in fx LightRoom!!

Come on Apple - When will there be an update for this??
