"Andromeda" returned home later that year and began a lengthy refit. She was assigned to the China Station in 1904 and returned home three years later. The ship was reduced to reserve at Chatham Dockyard upon her return, but transferred to Devonport Dockyard shortly afterwards. "Andromeda" was assigned to the 9th Cruiser Squadron of the new reserve Third Fleet in 1912. The following year the ship was converted to a boys' training ship and renamed "Powerful II" on 23 September 1913. She was later renamed "Impregnable II" in November 1919 and finally, HMS "Defiance" on 20 January 1931, when she became part of the torpedo school. The ship was sold for scrap in 1956 and arrived at Burgt, Belgium, on 14 August to begin demolition.
