High CPU usage, causing box to power off.

Hi

Any ideas why Mimic cause high cpu usage.

Kodi using Mimic, then go into any addon.
The amp/watt meter shows it pulling over 8 watts and trips the box into instant power-off.

Confluence and Amber skin works fine, 3 to 4 watts.

S905 android box ( Kodi 16)

Cheers
