MediaTek Helio A25

Ultra-efficient octa-core with advanced connectivity and location services for ‘everybody’ 4G smartphones

The MediaTek Helio A25 brings octa-core CPU performance, advanced connectivity and global location services to everyone. Its powerful octa-core ARM Cortex-A53 CPU operates up to 1.8GHz and combined with the IMG PowerVR GE8320-class graphics processor it’s perfect for everyday apps and a splash of gaming. Brands can build enticing tall and slim, 20:9 ratio HD+ (1600 x 720) resolution smartphones that offer a great balance between sharpness and power-efficiency, and with its flexible LPDDR3/LPDDR4x memory controller, device manufacturers can easily choose to meet their design needs.

MediaTek CorePilot technology provides power aware scheduling, thermal management and UX monitoring, assigning the right workload to the right resources to perfectly match the required performance with best power efficiency. This results in a sustained high-performance and consistently reliable user-experience.

MediaTek Heilo A25 brings the ultra-efficient TSMC 12nm FinFET production process to the entry 4G smartphone segment, boosting battery life in smartphones. Compared to direct competitors the A25 is over up to 38% more power efficient, while also boosting CPU performance by up to 9% and GPU up to 12%.

Impressive image quality enhancements and light-AI support

The MediaTek Helio A25 supports up to 13+5MP dual camera system and single cameras up to 16MP with AI-bokeh for portrait pictures.

MediaTek’s Electronic Image Stabilization (EIS) has been upgraded with a new Rolling Shutter Compensation (RSC) engine, which now combined, cleverly mitigates warped (‘jello effect’) video when capturing fast action or panning.

In-line with the existing MediaTek Helio P series, the new A25 has incredible low-light performance, multi-frame noise reduction and a clear-image zoom technology. Further, the Imagiq capture suite includes enhancements that automatically minimize aliasing, grain, and provides defect/distortion correction techniques. 3A includes MediaTek’s Instant Auto Exposure (AE): anti-over exposure hardware with accurate point focusing. The Instant AE is powered by a hardware Camera Control Unit (CCU) that delivers considerably faster focusing exposure adjustment when environmental lighting conditions change suddenly.

Light AI-enhancements such as facial recognition security bring convenience to entry and mainstream 4G smartphones. With MediaTek NeuroPilot support, developers and device makers have the best possible ecosystem that supports many common AI frameworks, and full compliance with Android Neural Networks API (Android NNAPI).

Dual 4G SIM support, Global GNSS and Bluetooth 5

The A25 brings focuses on a highly power-efficient design with dual 4G SIM support and VoLTE/ViLTE service capability and WorldWide IMS support (161 carriers) providing the fastest time to global markets. MediaTek TAS 2.0 smart antenna technology uses the best antenna combination to provide optimal signal quality at lowest power use, further enhancing performance and user experience.

Global multi-GNSS options (GPS, Glonass, Beidou, Galileo) with core-enhancements providing 57% improvement in Hot TTFF and 2.7X lower deviation than competitors.

In sync with latest range of smart home devices and routers, integrated Bluetooth 5 provides up to 2X speeds and 4X range and 8X broadcast capacity over the previous generation, plus BT and Wi-Fi (now 802.11ac) simultaneous co-existence can provide up to 5X Wi-Fi throughput boost over the previous generation.
