Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation
	The condensed consolidated financial statements as of April 4, 2015 and for the three months ended April 4, 2015 and March 29, 2014, include, in the opinion of management, all adjustments (consisting of normal recurring adjustments and reclassifications) necessary to present fairly the condensed consolidated balance sheets, statements of operations, statements of comprehensive income, statement of stockholders' equity, and statements of cash flows of Motorola Solutions, Inc. (“Motorola Solutions” or the “Company”) for all periods presented.
	Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Form 10-K for the year ended December 31, 2014. The results of operations for the three months ended April 4, 2015 are not necessarily indicative of the operating results to be expected for the full year.
	The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers." This new standard will replace most existing revenue recognition guidance in U.S. GAAP. The core principle of the ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount it expects to receive for those goods and services. This ASU requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and estimates and changes in those estimates. This ASU will be effective for the Company beginning January 1, 2017; however, in April 2015, the FASB proposed a one year delay in the effective date of the standard. This ASU allows for both retrospective and modified-retrospective methods of adoption. The Company is in the process of determining the method of adoption it will elect and is currently assessing the impact of this ASU on its consolidated financial statements and footnote disclosures.
	In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis." ASU 2015-02 changes the consolidation analysis required for limited partnerships and other variable interest entities. This ASU will be effective for the Company beginning January 1, 2016, with early adoption permitted. This ASU allows for either retrospective or modified retrospective application.  The Company does not expect this ASU will have a material impact on its consolidated financial statements.
	In April 2015, the FASB issued ASU No. 2015-03, "Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” Under this guidance, debt issuance costs related to a recognized debt liability are required to be presented in the balance sheet as a direct reduction from the carrying amount of such debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this guidance. The Company will be required to apply a full retrospective approach to all periods presented. This guidance will be effective January 1, 2016 and, upon adoption, debt issuance costs capitalized in other assets in the consolidated balance sheet will be reclassified and presented as a reduction to long-term debt. As of April 4, 2015, debt issuance costs, net of accumulated amortization, recognized in the condensed consolidated balance sheet were $19 million.
	In April 2015, the FASB issued ASU No. 2015-05, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement." Under this guidance, if it is determined that a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses; however, if it is determined that a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. This ASU allows for the option of applying either a full retrospective approach to all periods presented or a prospective approach to all arrangements entered into or materially modified after the effective date of January 1, 2016. The Company is in the process of assessing the impact of this ASU on its consolidated financial statements and footnote disclosures.

	As of April 4, 2015, the Company had outstanding foreign exchange contracts with notional amounts totaling $694 million, compared to $628 million outstanding at December 31, 2014. The Company does not believe these financial instruments should subject it to undue risk due to foreign exchange movements because gains and losses on these contracts should generally offset gains and losses on the underlying assets, liabilities and transactions.
	The following table shows the five largest net notional amounts of the positions to buy or sell foreign currency as of April 4, 2015, and the corresponding positions as of December 31, 2014:

	Interest Rate Risk
	As of April 4, 2015, the Company had $3.4 billion of long-term debt, including the current portion, which is primarily priced at long-term, fixed interest rates.
	One of the Company’s European subsidiaries has Euro-denominated loans. The interest on the Euro-denominated loans is variable and the Company has an interest rate swap in place which is not designated as a hedge. As such, the changes in the fair value of the interest rate swap is included in Other income (expense) in the Company’s condensed consolidated statements of operations. The fair value of the interest rate swap was in a liability position of $2 million at April 4, 2015 and December 31, 2014.
	Counterparty Risk
	The use of derivative financial instruments exposes the Company to counterparty credit risk in the event of non-performance by counterparties. However, the Company’s risk is limited to the fair value of the instruments when the derivative is in an asset position. The Company actively monitors its exposure to credit risk. As of April 4, 2015, all of the counterparties have investment grade credit ratings. As of April 4, 2015, the Company had $2 million of exposure to aggregate net credit risk with all counterparties.
	The following tables summarize the fair values and location in the condensed consolidated balance sheets of all derivative financial instruments held by the Company as of April 4, 2015 and December 31, 2014:

Income Taxes	Income Taxes
	At the end of each interim reporting period, the Company makes an estimate of the annual effective income tax rate. Tax items included in the annual effective income tax rate are pro-rated for the full year and tax items discrete to a specific quarter are included in the effective income tax rate for that quarter. The estimate used in providing for income taxes on a year-to-date basis may change in subsequent interim periods.
	The following table provides details of income taxes:

	Earnings before income taxes	$	128		$	89
	Income tax expense	40			4
	Effective tax rate	31		%	4		%
	The Company recorded $40 million of net income tax expense in the first quarter of 2015, resulting in an effective tax rate of 31%, compared to $4 million of net tax expense, resulting in an effective tax rate of 4% in the first quarter of 2014. The effective tax rate in 2015 was lower than the U.S. statutory tax rate of 35% primarily due to the U.S. domestic production tax deduction and rate differential for foreign affiliates. The effective tax rate in the first quarter of 2014 was lower than the U.S. statutory tax rate of 35% due to a $30 million net tax benefit associated with the net reduction in unrecognized tax benefits for facts that indicated the extent to which certain tax positions were more-likely-than-not of being sustained.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	The Company holds certain fixed income securities, equity securities and derivatives, which are recognized and disclosed at fair value in the financial statements on a recurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. Fair value is measured using the fair value hierarchy and related valuation methodologies as defined in the authoritative literature. This guidance specifies a hierarchy of valuation techniques based on whether the inputs to each measurement are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's assumptions about current market conditions.
	The fair value hierarchy and related valuation methodologies are as follows:
	Level 1—Quoted prices for identical instruments in active markets.
	Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets.
	Level 3—Valuations derived from valuation techniques, in which one or more significant inputs are unobservable.
	The fair values of the Company’s financial assets and liabilities by level in the fair value hierarchy as of April 4, 2015 and December 31, 2014 were as follows:
	April 4, 2015	Level 1		Level 2		Total

	The Company had no Level 3 holdings as of April 4, 2015 or December 31, 2014.
	At April 4, 2015 and December 31, 2014, the Company had $2.5 billion and $3.3 billion, respectively, of investments in money market mutual funds (Level 2) classified as Cash and cash equivalents in its condensed consolidated balance sheets. The money market funds had quoted market prices that are equivalent to par.
	Using quoted market prices and market interest rates, the Company determined that the fair value of long-term debt at April 4, 2015 was $3.6 billion (Level 2).
	All other financial instruments are carried at cost, which is not materially different from the instruments’ fair values.

Long-term Customer Financing and Sales of Receivables	Long-term Customer Financing and Sales of Receivables
	Long-term Customer Financing
	Long-term customer financing receivables consist of trade receivables with payment terms greater than twelve months, long-term loans and lease receivables under sales-type leases. Long-term customer financing receivables consist of the following:
		April 4,			December 31,
		2015			2014
	Long-term receivables	$	51		$	49
	Less current portion	(25		)	(18		)
	Non-current long-term receivables, net	$	26		$	31
	The current portion of long-term receivables is included in Accounts receivable, net and the non-current portion of long-term receivables is included in Other assets in the Company’s condensed consolidated balance sheets. The Company had outstanding commitments to provide long-term financing to third parties totaling $65 million at April 4, 2015, compared to $293 million at December 31, 2014. Outstanding commitments decreased during the first quarter of 2015 primarily as a result of two large customer contracts one of which was converted to an order without long-term financing and the other where the financing commitment was funded and sold.
	Sales of Receivables
	The following table summarizes the proceeds received from sales of accounts receivable and long-term receivables for the three months ended April 4, 2015 and March 29, 2014:

	At April 4, 2015, the Company had retained servicing obligations for $596 million of long-term receivables, compared to $496 million of long-term receivables at December 31, 2014. Servicing obligations are limited to collection activities related to the sales of accounts receivables and long-term receivables.
	Credit Quality of Customer Financing Receivables and Allowance for Credit Losses
	An aging analysis of financing receivables at April 4, 2015 and December 31, 2014 is as follows:

	Legal Matters
	The Company is a defendant in various suits, claims and investigations that arise in the normal course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Company’s condensed consolidated financial position, liquidity or results of operations. However, an unfavorable resolution could have a material adverse effect on the Company’s: (i) results of operations in the periods in which an adverse outcome becomes both probable and estimable or (ii) financial position or liquidity in the periods in which the matters are ultimately resolved.
	Other Indemnifications
	The Company is a party to a variety of agreements pursuant to which it is obligated to indemnify the other party with respect to certain matters. In indemnification cases, payment by the Company is conditioned on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party's claims. In some instances, the Company may have recourse against third parties for certain payments made by the Company.
	Some of these obligations arise as a result of divestitures of the Company's assets or businesses and require the Company to indemnify the other party against losses arising from breaches of representations and warranties and covenants and, in some cases, the settlement of pending obligations. The Company's obligations under divestiture agreements for indemnification based on breaches of representations and warranties are generally limited in terms of duration and to amounts not in excess of a percentage of the contract value. The Company had no accruals for any such obligations at April 4, 2015.
	In addition, the Company may provide indemnifications for losses that result from the breach of general warranties contained in certain commercial and intellectual property agreements. Historically, the Company has not made significant payments under these agreements.

Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers." This new standard will replace most existing revenue recognition guidance in U.S. GAAP. The core principle of the ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount it expects to receive for those goods and services. This ASU requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and estimates and changes in those estimates. This ASU will be effective for the Company beginning January 1, 2017; however, in April 2015, the FASB proposed a one year delay in the effective date of the standard. This ASU allows for both retrospective and modified-retrospective methods of adoption. The Company is in the process of determining the method of adoption it will elect and is currently assessing the impact of this ASU on its consolidated financial statements and footnote disclosures.
	In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis." ASU 2015-02 changes the consolidation analysis required for limited partnerships and other variable interest entities. This ASU will be effective for the Company beginning January 1, 2016, with early adoption permitted. This ASU allows for either retrospective or modified retrospective application.  The Company does not expect this ASU will have a material impact on its consolidated financial statements.
	In April 2015, the FASB issued ASU No. 2015-03, "Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” Under this guidance, debt issuance costs related to a recognized debt liability are required to be presented in the balance sheet as a direct reduction from the carrying amount of such debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this guidance. The Company will be required to apply a full retrospective approach to all periods presented. This guidance will be effective January 1, 2016 and, upon adoption, debt issuance costs capitalized in other assets in the consolidated balance sheet will be reclassified and presented as a reduction to long-term debt. As of April 4, 2015, debt issuance costs, net of accumulated amortization, recognized in the condensed consolidated balance sheet were $19 million.
	In April 2015, the FASB issued ASU No. 2015-05, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement." Under this guidance, if it is determined that a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses; however, if it is determined that a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. This ASU allows for the option of applying either a full retrospective approach to all periods presented or a prospective approach to all arrangements entered into or materially modified after the effective date of January 1, 2016. The Company is in the process of assessing the impact of this ASU on its consolidated financial statements and footnote disclosures.
