Vivo T4

The Vivo T4 establishes an industry benchmark for marathon battery longevity, curved AMOLED ergonomics, and balanced 4nm performance in Bangladesh's competitive mid-range 5G category. Masterfully engineered with equal-depth quad-curved contours measuring an ultra-slender 163.4 x 76.4 x 7.9 mm and weighing 199 grams, the phone incorporates high-density BlueVolt silicon-carbon battery chemistry to pack a colossal 7300 mAh cell into an under-8mm chassis, finished in dynamic Emerald Blaze and Phantom Grey colors, fully protected by certified IP65 dust-tight and water jet resistance. Dominating the front is an expansive 6.77-inch Full HD+ (1080 x 2392 pixels) quad-curved AMOLED punch-hole display boasting an 88.8% screen-to-body ratio, a fluid 120Hz refresh rate, 388 ppi pixel density, eye-protective 3840Hz high-frequency PWM dimming, 10-bit color reproduction (1.07 billion colors), HDR10+ certification, and a market-leading 5000 nits local peak brightness, protected by Shield Glass with an integrated on-screen optical fingerprint scanner. Under the hood, it is powered by Qualcomm's efficient 4nm Snapdragon 7s Gen 3 5G octa-core processor (1x2.5 GHz Cortex-A720 + 3x2.4 GHz Cortex-A720 + 4x1.8 GHz Cortex-A520) alongside an Adreno 710 GPU and an integrated liquid cooling vapor chamber, coupled with 8GB of LPDDR4X RAM (supported by Extended RAM virtual memory adding up to +8GB/12GB) and up to 256GB of UFS 2.2 internal storage, expandable up to 1TB via microSD. Mobile photography is driven by an AI dual rear camera array headlined by a 50MP primary sensor (f/1.8) featuring hardware Optical Image Stabilization (OIS) and 4K Ultra HD video capture, accompanied by a 2MP depth sensor, complemented by a sharp 32MP front selfie camera. Powered by a class-leading 7300 mAh battery supported by 90W wired FlashCharge, 55W PPS, 44W UFCS, and 7.5W reverse wired charging over USB Type-C, dual stereo speakers, Wi-Fi 6, Bluetooth 5.2, an IR blaster, and Funtouch 15 based on Android 15 out of the box, the Vivo T4 stands as a premier stamina powerhouse and modern curved daily driver.
