Samsung Galaxy S24 (SM-S921B) / Google Pixel 8 Pro

The adaptive refresh rate drops to 1 Hz on static content to save power; Vision Booster adjusts tone and contrast in bright light.

An LTPO panel can drop the refresh rate as low as 1 Hz for static content, saving power with the always-on display and while reading, and rises to 120 Hz for motion. Google notes it is not available for all apps or content. Because the corners are rounded, the actual viewable area is less than 6.7 inches.

Samsung notes that the processor varies by market; the US SM-S921U does not use the same chip as this global model.

Tensor G3 includes a TPU that accelerates on-device AI models. Titan M2 is a separate security chip that protects the lock screen and encryption keys.

The series also has 256 and 512 GB and 12 GB RAM configurations; there is no microSD slot.

Storage options vary by region and channel; there is no memory card slot.

3x optical zoom uses the separate telephoto lens; the 2x option crops the main sensor at optical quality, and digital zoom reaches 30x.

Optical and electronic stabilisation work together on the wide and telephoto cameras. Zoom beyond 5x is digital. Pro controls allow manual shutter, ISO and focus and high-resolution (50 MP) shots. A multi-zone laser autofocus sensor helps focus in low light.

Video Boost uploads video to Google’s servers to reprocess colour, lighting and stabilisation; it needs the Google Photos app and the result is not instant. Night Sight Video uses this processing in low light.

The standard Pixel 8 has a fixed-focus front camera; the autofocus on the 8 Pro keeps close selfies sharp.

Wireless PowerShare lets the back of the phone wirelessly charge small devices such as a watch or earbud case. No adapter is included.

Google quotes beyond 24-hour battery life and up to 72 hours in Extreme Battery Saver (many features including 5G off). Figures use the separately sold Google 30 W USB-C charger (USB-PD 3.0 PPS). Battery Share significantly reduces the phone’s battery life.

The 2000-cycle figure comes from the EU label, which targets the battery keeping a set share of its capacity over that span.

The 6 GHz band needs a Wi-Fi 6E router.

Samsung’s UK page lists security updates for this model until 31 January 2031; timing can vary by market.

Resistance can diminish over time; liquid damage voids the warranty.

Colour availability varies by region.

Google measures the HDR figure at a 100% on-pixel ratio and the peak figure at a 5% on-pixel ratio; 2,400 nits is a ceiling for small bright areas.

The matte back shows fewer fingerprints; the standard Pixel 8 has a polished back and a matte frame.

Google says the sensor can measure the temperature of an object, such as a pan or milk in a baby’s bottle. Google said it applied to the FDA for body-temperature use; that use depends on the country.

Wi-Fi 6E is listed in Japan and Wi-Fi 6 in Taiwan, Singapore and India. Ultra-Wideband measures direction and distance to compatible devices.

eSIM support depends on the operator.

The bundled cable runs at USB 2.0 speed. There is no headphone jack. A Quick Switch adapter is in the box.

The period counts from when the device first became available on the US Google Store (12 October 2023).
