The latest 5G standard is not supported by the Pixel 7 line
Power saving features in 3GPP’s Release 16
For example, Qualcomm wrote, “In Release 16, several new power-saving features were introduced. For instance, a new wakeup signal (WUS) can let the device know if a transmission is pending or allowing it to stay in low-power mode, skipping the next low-power DRX (discontinuous reception) monitoring period. Others include optimized low-power settings, overhead reduction, and more efficient power control mechanisms.”
Googler reveals that the Pixel 7 series launched with Release 15
The Pixel 8 and Pixel 8 Pro will likely be powered by the Google Tensor 3 SoC, but both are expected to sport the same Exynos 5300 5G modem chip used on the 2022 Pixel models. Samsung’s website says that the Exynos 5300 is “3GPP Release 16-compliant.”
In case you were wondering, the iPhone 14 line, with the Snapdragon X65 5G modem, supports Release 16. The Galaxy S22 series also carries Release 16 support.
