"Kronprinz" participated in a fleet operation into the North Sea which ended without combat from 29 until 31 May 1915. In August, Constanz Feldt replaced Dalwigk zu Lichtenfels as the ship's captain. The ship supported a minelaying operation on 11–12 September off Texel. The fleet conducted another sweep into the North Sea on 23–24 October. Several uneventful sorties followed on 5–7 March 1916, 31 March and 2–3 April. "Kronprinz" supported a raid on the English coast on 24 April 1916 conducted by the German battlecruiser force of I Scouting Group. The battlecruisers left the Jade Estuary at 10:55 CET, and the rest of the High Seas Fleet followed at 13:40. The battlecruiser struck a mine while en route to the target, and had to withdraw. The other battlecruisers bombarded the town of Lowestoft unopposed, but during the approach to Yarmouth, they encountered the British cruisers of the Harwich Force. A short gun duel ensued before the Harwich Force withdrew. Reports of British submarines in the area prompted the retreat of I Scouting Group. At this point, Admiral Reinhard Scheer, who had been warned of the sortie of the Grand Fleet from its base in Scapa Flow, also withdrew to safer German waters.
