Although it's late, thank you for all the comments.
Now, bringing
Berlin to a conclusion:
After returning to the Recon Forces, the cruiser was retired the following year with most of her crew moving to the new cruiser SMS
Straßburg.
With the outbreak of the war,
Berlin was reactivated and put into the IV. Recon Group. In this position, she mostly performed guard and picket duties in the North Sea, before being transferred to the Baltic in late 1915. After a short stint there, replacing her sister
Bremen, she returned to the Recon Forces and the North Sea in January of 1916.
Berlin did not participate in the Battle of Jutland because at the time she was in drydock for over two months. In October of 1916 she came under attack from the British submarine
E38, which missed with her torpedoes, but damaged her sister
München instead. The cruiser survived but had to be tugged back by
Berlin. In 1917
Berlin was transferred to Danzig where she was decommissioned, disarmed and used as a tender for the remainder of the war.
Berlin was one of the six remaining active cruisers of the new Weimar Republic after the war and was reactived in 1919 as s training ship for stokers. In 1921-1922 the cruiser was rebuilt, even more so than her sister
Hamburg:
The old ramming bow was replaced with a cruiser bow, which included the removal of the forward casemates. The bridge wings were extended and rangefinders installed, the bridge itself was connected with the mast with a bridge. The mast itself received an enclosed spotting platform and the number of forward searchlights was reduced to one. The compass platform was removed and the aft superstructure extended with another rangefinder platform. All the 105mm SK L/40 were replaced with the L/45 model, although she now only had eight of them. The underwater torpedo tubes were removed and instead two deck-mounted tubes behind the middle guns were added. Interestingly, the small aft casemates were kept, although they had been removed on her sister
Hamburg.
Returning to the fleet as a training cruiser,
Berlin made several training tours to foreign lands, including Spain, Portugal, East Asia and South America.
Berlin was also the first ship to visit Australia since the end of the war in 1928. On March 27th, 1929, after returning from her last world tour, she was deactivated once again and put into reserve, her crew moving over to the new cruiser
Karlsruhe.
From 1936 onwards and during World War 2, the cruiser was used as a depot ship in Kiel. She survived the war and was handed over to the British, who loaded the ship with gas ammunition and sunk it in the Skagerrak.
