Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The condensed consolidated financial statements as of September 27, 2025 and for the three and nine months ended September 27, 2025 and September 28, 2024 include, in the opinion of management, all adjustments (consisting of normal recurring adjustments and reclassifications) necessary to state fairly the Condensed Consolidated Balance Sheets, Statements of Operations, Statements of Comprehensive Income, Statements of Stockholders' Equity, and Statements of Cash Flows of Motorola Solutions, Inc. (“Motorola Solutions” or the “Company”) for all periods presented. The Company operates on a 52-week fiscal year, with each fiscal year ending on December 31. With respect to each fiscal quarter, the Company operates on a 13-week fiscal quarter, with all fiscal quarters ending on a Saturday. Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States 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, 2024 (the "Form 10-K"). The results of operations for the three and nine months ended September 27, 2025 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 And Recently Adopted Accounting Pronouncements	Recent Accounting Pronouncements In September 2025, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2025-06, "Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software" to modernize the accounting for internal-use software costs. The ASU is effective for fiscal years beginning after December 15, 2027 and interim periods with annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is still evaluating the complete impact of the adoption of this ASU on its financial statements and disclosures. In July 2025, the FASB issued ASU No. 2025-05, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets" to introduce a practical expedient in the estimation of expected credit losses for current accounts receivable and current contract assets. The ASU is effective for fiscal years beginning after December 15, 2025 and interim periods with annual reporting periods beginning after December 15, 2025, with early adoption permitted. The Company is still evaluating the complete impact of the adoption of this ASU on its financial statements and disclosures. In November 2024, the FASB issued ASU No. 2024-03, "Disaggregation of Income Statement Expenses" (DISE), to enhance disclosures relating to key income statement expense topics. This was subsequently amended by ASU No. 2025-01, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date," which clarified the effective dates. The ASU is effective for fiscal years beginning after December 15, 2026 and interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is still evaluating the complete impact of the adoption of this ASU on its disclosures. In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which expands disclosures in an entity's income tax rate reconciliation table and disclosures regarding cash taxes paid both in the U.S. and foreign jurisdictions. This ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company anticipates that it will have additional disclosures regarding cash taxes and the income tax rate reconciliation once it adopts this ASU. Recently Adopted Accounting Pronouncements In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” to update reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses and information used to assess segment performance.
