Windows 8 Excessive CPU Usage with OneDrive

OneDrive and .NET Optimization services are sucking CPU cyclescausing ultra fast battery drain.

I have a dual battery Lenovo T420s and the battery went from full to half in about 40 minutes. The CPU cooling fan is also getting a hell of a work out.

Once I killed the oneDrive tray app, the fan slowed down to a negligible speed. the suddenly it sped up again within a minute or so.

.Net Optimization service was the culprit this time.

Let be frank. Can these CPU and  battery hogging services have the ability to run while plugged in instead of while on battery.

UPDATE:
On my Surface Pro 2, Skydrive tanks the CPU, running, syncing, the unit gets very warm. Once I stop the Onedrive service. the unit settles down.
