Acer Acerone Liquid S272E4

The Acer Acerone Liquid S272E4 has a conventional, non-folding form factor with a height of 171 mm and a width of 78.6 mm, giving it a tall footprint typical of modern large-screen phones. At 8.9 mm thick and weighing 200 g, the device sits on the moderately substantial side in terms of heft. It carries no rugged certification and offers no water resistance, so it is not designed to withstand harsh environmental conditions.

The Acer Acerone Liquid S272E4 features a 6.75″ IPS LCD touchscreen with a resolution of 720 x 1600 px and a pixel density of 260 ppi, delivering a reasonably sized viewing area suited to everyday media consumption. Typical brightness is rated at 350 nits, and the panel is protected by Gorilla Glass 4, offering a degree of scratch and impact resistance. The display does not support HDR10, HDR10+, or Dolby Vision, and there is no Always-On Display mode or secondary screen.

The Acer Acerone Liquid S272E4 is powered by the MediaTek Helio P35, an octa-core chipset built on a 12 nm process that uses big.LITTLE technology with four cores running at 2.3 GHz and four at 1.8 GHz, supported by 8 threads and a turbo clock of 2.3 GHz. It is paired with 4 GB of DDR4 RAM running at 1600 MHz, a maximum supported memory ceiling of 6 GB, and 64 GB of eMMC 5.1 internal storage. Graphics are handled by the integrated PowerVR GE8320 GPU clocked at 650 MHz with a turbo of 680 MHz, supporting DirectX 10, OpenGL 3.2, OpenGL ES 3.2, and OpenCL 1.2, while maximum memory bandwidth reaches 14.9 GB/s. The chipset scores 164 in Geekbench 6 single-core and 744 in multi-core, operates within a 5W TDP envelope, and includes integrated LTE, NX bit, TrustZone, and HMP for security and efficient task scheduling.

The Acer Acerone Liquid S272E4 features a dual-lens rear camera system with a 20 MP main sensor and a 0.3 MP secondary lens, both using a CMOS sensor without back-side illumination. Video recording tops out at 1080p at 30 fps, with support for slow-motion recording, though HDR10 and Dolby Vision recording are not available. Autofocus options include phase-detection and touch autofocus as well as continuous autofocus during video, while laser autofocus is absent. Manual controls cover exposure, ISO, focus, and white balance, though manual shutter speed is not included, and the camera also supports burst mode, HDR stills, and in-camera panoramas but cannot shoot in RAW format or capture 360-degree panoramas. A single LED flash is present on the rear, while the front camera offers 5 MP with no accompanying flash, no secondary lens, and is positioned conventionally rather than under the display.

The Acer Acerone Liquid S272E4 runs Android 14, an open-source platform that supports multiple user accounts, offline voice recognition, voice commands, and on-device machine learning. On the privacy side, it includes clipboard warnings, location privacy options, camera and microphone access controls, and the ability to block app tracking, though cross-site tracking blocking and Mail Privacy Protection are not present. Customization options are broad, covering dynamic theming, theme customization, dark mode, an extra dim mode, customizable notifications, and home screen widgets. Productivity features include split-screen multitasking, picture-in-picture mode, full-page screenshots, a media picker, sharing intents, Live Text, and the ability to play games while they are still downloading. A battery health check and device tracking are also available, while focus modes, app offloading, Wi-Fi password sharing, Quick Start, and the ability to function as a PC are not supported. Direct OS updates from the vendor are not provided.

The Acer Acerone Liquid S272E4 is equipped with a 5000 mAh rechargeable battery that includes a battery level indicator for monitoring charge status. The cell is non-removable, and the device does not support wireless charging or fast charging, meaning it relies solely on standard wired charging to replenish power.

The Acer Acerone Liquid S272E4 includes a 3.5 mm headphone jack for wired audio output and a built-in radio for FM listening. Speaker output is mono, as stereo speakers are not present. On the wireless audio side, the device does not support aptX, aptX HD, aptX Adaptive, aptX Lossless, or LDAC, meaning higher-quality Bluetooth audio codecs are unavailable.

The Acer Acerone Liquid S272E4 supports dual-SIM operation with a cellular module, Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac), and Bluetooth 5, while 5G is not available. Wired connectivity is handled via a USB Type-C port running USB 2.0, and there is no HDMI output. Download speeds reach up to 300 Mbit/s and upload up to 150 Mbit/s. Location capabilities include GPS and Galileo support, backed by an accelerometer, though there is no gyroscope, compass, or barometer on board. The device has a fingerprint scanner for biometric authentication but does not offer 3D facial recognition or an iris scanner. An external memory slot is available for storage expansion, while NFC, ANT+, infrared sensor, DLNA certification, heart rate monitor, crash detection, satellite SOS, motion tracking, optical tracking, and a built-in projector are all absent.

The Acer Acerone Liquid S272E4 includes a video light to assist with illumination during video recording. The display is flat rather than curved and uses neither sapphire glass nor an e-paper panel.
