Immersive 6.88-Inch High Refresh Rate Display
A cornerstone of the Redmi A5 is its expansive 6.88-inch display, designed for an immersive experience where users can lose themselves in films, books, and documents. With a resolution of 1640×720 and 260 ppi, the screen provides clear visuals backed by a 1500:1 contrast ratio, 8-bit color depth, and 70% NTSC gamut coverage at 450 nits typical brightness. The 90% screen-to-body ratio (AA/CG) maximizes viewing space within the slim frame. Performance is smooth thanks to an adaptive refresh rate of up to 120Hz for supported apps, fulfilling the promise of a smoother and more immersive experience, accompanied by a 240Hz touch sampling rate for responsive input. Wet touch technology maintains precise touch control even with wet hands. Eye comfort is central, boasting full DC dimming, low blue light, no visible flicker, and TÜV Rheinland certifications for Low Blue Light (Software Solution), Flicker Free, and Circadian Friendly (via OTA update). This delivers a book-like reading experience safe for long sessions without damaging your eyes.

Coupled with 3GB of RAM and 64GB of internal storage (expandable via microSD through the dual SIM tray), it handles daily communication and media tasks competently. The device runs Android 15 (Go Edition), a streamlined operating system designed for efficient operation on modest hardware. Xiaomi supports this with 3 years of security patch updates, ensuring the device remains protected and functional over an extended lifespan. This combination of a power-efficient processor and optimized software makes the phone ideal for essential smartphone activities.
