     The fact is that most UPS manufacturers quote UPS efficiency at 100% load because it represents the very best efficiency the UPS will attain. If this UPS runs at 50% of the load, will it have same efficiency or not?

    The internal losses are constant, so the closer the device is operating at full load the more efficient.

    The answer to your question is that it will not be as efficient at 50% load.
