Upon commissioning, "Emperor of India" joined the 4th Battle Squadron of the Grand Fleet, based at Scapa Flow. She took part in numerous sorties into the northern North Sea to enforce the blockade of Germany, along with frequent training exercises and gunnery drills. "Emperor of India" was in dock for a refit in late May 1916, so she was unavailable for the Battle of Jutland. The increased danger from submarines led both the Grand Fleet and the German High Seas Fleet to pursue more cautious strategies after Jutland, which led to a less eventful war.
