Samsung Galaxy S24 (SM-S921B) / Google Pixel 9 Pro XL

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

LTPO lets the panel drop as low as 1 Hz with static content to save battery and rise to 120 Hz when scrolling; Google notes 120 Hz is not available in every app. The 2000-nit HDR figure is measured with the whole screen lit, the 3000-nit peak with 5% of the screen lit.

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

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

Storage is chosen at purchase and cannot be expanded; 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.

Google lists 0.5x, 1x, 2x, 5x and 10x as optical-quality zoom; the range up to 30x is software-assisted digital zoom. The wide and telephoto cameras have optical + electronic stabilisation, and there is a multi-zone laser autofocus sensor.

Video Boost processes footage on Google’s cloud servers to improve night and 8K recordings, so the processed result is not instant and needs an internet connection.

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

No charger is included; the box has a USB 2.0 USB-C cable. Google notes Battery Share noticeably reduces the phone’s own 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.

Wi-Fi 7 gives higher speed and lower latency on the 6 GHz band with a compatible router; the Indian version supports only Wi-Fi 6 (2.4/5 GHz). The USB-C port runs at USB 3.2 speed, but the bundled cable is USB 2.0.

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

IP68 is the dust and water resistance class under IEC 60529; Google notes the protection is not permanent and can weaken with wear, repair or damage.

Titan M2 is a security chip that handles sensitive operations such as passcode and lock-screen verification separately from the main processor.

Dual-band satellite positioning helps reduce errors from signals reflected between tall buildings.

Satellite SOS is offered only in the US and is free for the first two years; Car Crash Detection is not available in every country or language.
