| Fiscal Period, Policy | We operate and report using a 52-53 week fiscal year ending on the last Sunday in September. Each of the three months ended December 25, 2022 and December 26, 2021 included 13 weeks. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Use of Estimates, Policy | The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in our condensed consolidated financial statements and the accompanying notes. Actual results could differ from those estimates. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue Recognition | We disaggregate our revenues by segment (Note 7), by products and services (as presented on our condensed consolidated statement of operations), and for our QCT (Qualcomm CDMA Technologies) segment, by revenue stream, which is based on the industry and application in which our products are sold (as presented below). Beginning in the first quarter of fiscal 2023, QCT RFFE (radio frequency front-end) revenues, which were previously presented as a separate revenue stream, are now included within our Handset, Automotive and internet of things (IoT) revenue streams, as applicable, based on the industry and application in which the related RFFE products are sold. Prior period information has been recast to reflect this change. RFFE revenues include revenues from the sale of 4G, 5G sub 6 and 5G millimeter wave RFFE products (a substantial portion of which relate to mobile handsets) and exclude radio frequency transceiver components. This change aligns with changes made to our internal reporting of revenues. We believe this change provides a more meaningful presentation in understanding QCT revenues going forward, as we expect RFFE revenues to correspond with trends in Handsets, Automotive and IoT (as applicable) and is more consistent with how our revenue diversification is viewed externally. In certain cases, the determination of QCT revenues by industry and application requires the use of certain assumptions. Substantially all of QCT’s revenues consist of equipment revenues that are recognized at a point in time, and substantially all of QTL’s (Qualcomm Technology Licensing) revenues represent licensing revenues that are recognized over time and are principally from royalties generated through our licensees’ sales of mobile handsets. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Earnings Per Common Share, Policy |
Earnings Per Common Share. Basic earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding during the reporting period. Diluted earnings per share is computed by dividing net income by the combination of the weighted-average number of common shares outstanding and the weighted-average number of dilutive common share equivalents, comprised of shares issuable under our share-based compensation plans, during the reporting period. The following table provides information about the diluted earnings per share calculation (in millions):

| Segment Reporting Policy | We are organized on the basis of products and services and have three reportable segments. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Segment Reporting EBT Policy | Our CODM allocates resources to and evaluates the performance of our segments based on revenues and earnings (loss) before income taxes (EBT). Segment EBT includes the allocation of certain corporate expenses to the segments, including depreciation and amortization expense related to unallocated corporate assets. Certain income and charges are not allocated to segments in our management reports because they are not considered in evaluating the segments’ operating performance. Unallocated income and charges include certain interest expense, certain net investment income, certain share-based compensation, gains and losses on our deferred compensation plan liabilities and related assets and certain research and development expenses, certain selling, general and administrative expenses and other expenses or income that were deemed to be not directly related to the businesses of the segments. Additionally, unallocated charges include recognition of the step-up of inventories and property, plant and equipment to fair value, amortization of certain intangible assets and certain other acquisition-related charges, third-party acquisition and integration services costs and certain other items, which may include major restructuring and restructuring-related costs, asset impairment charges and awards, settlements and/or damages arising from legal or regulatory matters. Our CODM does not evaluate our operating segments using discrete asset information. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
