Alternatively, you can press Settings/Apps/See all xxx apps/Google Play services/App details, and it will redirect to the Google Play services page on Play store. Click "update" button and wait for it to finish.
This should address the CPU frequency raise and heat build-up issue caused by Google's SystemUpdate module. If it still happens after the update, let me know.
can you provide the 'Google Play services' version number that's bringing the fix?
I'm currently only seeing version '22.21.16 (190400-454906765)', and I don't think it includes the fix.
