DUT Specifics 1.1. Device under Test The device under test is a wireless device, incorporating the technologies listed in Part 1 RF Exposure report. This device uses the Qualcomm® Gen2 Smart Transmit feature to control and manage transmitting at all times for WWAN/WLAN/BT operations. Additionally, this device support NFC/WPC/UWB technologies, but the output power of these modes are not controlled by the Smart Transmit algorithm. RF Exposure Part 1 report in this report refers to report SN: 2026.006.01 1.2. Time-Averaging Algorithm for RF Exposure Compliance This device is enabled with the Qualcomm® Smart Transmit Gen2 feature. This feature implements a time- averaging algorithm in real time to control and manage transmitting power and ensure the time-averaged RF exposure is in compliance with FCC requirements all the time. This Part 0 report shows SAR characterization of Smart Transmit enabled radios. Characterization is achieved by determining P Limit for those radios that corresponds to the exposure design targets after accounting for all device design related uncertainty. The SAR characterization is denoted as SAR Char in this report. 1.3. Nomenclature Technology Term Description Sub6 WWAN/WLAN/BT P limit Power level that corresponds to the exposure design target (SAR_design_target) after accounting for all device design related uncertainties P max Maximum tune-up output power SAR_design_target Target SAR level < FCC SAR limit after accounting for all device design related uncertainties SAR Char Table containing P limit for all technologies and bands Next Generation Test Laboratory Inc.

SAR Characterization 2.1. DSI and SAR Determination This device uses different Device State Index (DSI) to configure different time averaged power levels based on certain exposure scenarios. Depending on the detection scheme implemented in the smartphone, the worst-case SAR was determined by measurements for the relevant exposure conditions for that DSI. Detailed descriptions of the detection mechanisms are included in the operational description. When 1g SAR and 10g SAR exposure comparison is needed, the worst-case was determined from SAR normalized to 1g or 10g SAR limit. The device state index (DSI) conditions used in Table 3-1 represent different exposure scenarios. Table 2-1 2.2. SAR design Target SAR_design_target is determined by ensuring that it is less than FCC SAR limit after accounting for total device designed related uncertainties specified by the manufacturer.

FCC ID: A3LSMF976B SAR-002: SAR Test Report RevA Test Report SN: 2026.006.01 Page G1 of G4 Appendix G: Power Reduction Verification G.1. Procedures According to May 2017 TCBC Workshop notes, demonstration of proper functioning of the power reduction mechanisms is required to support the corresponding SAR configurations. The verification process includes evaluation of device state index (DSI) for individual or multiple triggering mechanisms. This device supports manufacturer’s proprietary mechanism which configure the DSI with different time averaged power levels based on certain exposure scenarios. Details of this mechanism can be found in the Operational Description. The power verification was performed using a base station simulator to establish a conducted RF connection for relevant modes and frequency bands. The DSI as displayed on the DUT was recorded before and after the mechanism was triggered. G.2.

Measured SAR does not deviate from the calibrated SAR value by more than 10%. 2. Return loss does not deviate by more than 20% from the previous measurement (i.e. value in dB x 0.2) and meet the required minimum return-loss. 3. Real and imaginary part of the impedance do not deviate by more than 5 Ω from the previous measurement.
