The Atlantic Fleet returned to Hampton Roads on 17 March and conducted battle practice later that month and into April.
Idaho went back to Philadelphia for maintenance from 12 April to 4 May. From there, she steamed south to the Gulf Coast to cruise the Mississippi River as far north as Natchez, Mississippi.
Torpedo training off Pensacola followed in June, after which she once again went to Philadelphia for periodic maintenance.
The rest of the year's activities consisted of fleet maneuvers off the coast of Massachusetts in July and August, gunnery training off the Virginia Capes in August and September, another overhaul in September and October, and a naval review in November.
Idaho concluded the year with more repairs and sea trials, lasting until 2 January 1912.

Idaho joined the fleet off Hampton Roads on 3 January for war games.
Further fleet exercises were held off Cuba from 12 January to 10 February.
Her participation in these maneuvers was cut short when her starboard engine broke down, forcing her to return to Philadelphia on 17 February for repairs, which were completed in mid-August.
She got underway again on 23 August for Hampton Roads, rendezvousing with the rest of the fleet two days later.
Target and torpedo practice followed in September, an in early October she underwent full speed and endurance tests off the coast of Maine.
She took part in a naval review in New York City on 7 October, after which she returned to Hampton Roads for more shooting practice.
On 7 November, the ship was assigned to the Fourth Division of the fleet.
She conducted another round of target practice later that month and on 8 December she returned to Philadelphia for another period of maintenance.

Idaho left Philadelphia on 2 January 1913 to rendezvous with the fleet off Hampton Roads the next day.
The assembled ships then got underway on 6 January for Cuba, where torpedo practice and other maneuvers were conducted through mid-March, at which point the fleet returned to Hampton Roads for during training, including target practice.
These operations lasted into early April, and Idaho went to Philadelphia for maintenance from 10 to 16 April.
By this time, conditions in Mexico had seriously deteriorated during the Mexican Revolution, so the US Navy deployed warships to protect American interests in the country.
Idaho was sent to Tampico form 23 April to 22 May as part of these operations.
From there, she moved to Veracruz on 23 May, remaining there until 22 June when she left to rejoin the fleet.
Beginning on 30 June, the ship cruised off the coast of New England through July, followed by fleet maneuvers off Long Island in August.

She took on a contingent of midshipmen from the US Naval Academy for a training cruise that began on 7 June.
Idaho joined the battleship Missouri for a cruise of the Mediterranean.
While still abroad, sale of the ship was being negotiated with the Greek government.
Greece had become engaged in a naval arms race with the Ottoman Empire in the early 1910s; in 1910 the Ottomans had purchased a pair of German pre-dreadnoughts (renamed Barbaros Hayreddin and Turgut Reis) and ordered dreadnought battleships from Britain in 1911 and 1914.
The Royal Hellenic Navy ordered the dreadnought Salamis from Germany in 1913 and the dreadnought Basileus Konstantinos from France in response.
As a stop-gap measure, the Greeks purchased Mississippi and Idaho from the US Navy.
The Greek government bought the ships through an intermediary, the shipbuilder Fred Gauntlett, who acquired them on 8 July and handed them over to Greece.
In the meantime, Idaho and Missouri stopped in a number of ports in the region: Tangier, Morocco; Gibraltar; and Naples, Italy.
After the sale was finalized, Idaho left Missouri and steamed to Ville
