During the Battle of Jutland on 31 May 1916, she was on the unengaged side of the fleet and did not fire her 9.2 or 7.5-inch guns at all during the battle. The ship spent several days after the battle searching for survivors from her sister and other sunken ships. Before the end of the war the 12-pounder AA gun mounted on the aft superstructure was moved to the roof of the forward 9.2-inch gun turret. "Shannon" was paid off on 2 May 1919 and became an accommodation ship until sold for breaking up on 12 December 1922.
