Smartphone innovation has always been a race between power and portability. That’s where the upcoming vivo T4 5G steps in—bringing with it a game-changing combination: India’s slimmest smartphone with a 7300 mAh battery¹. 

Yes, you read that right. With the biggest battery ever in a smartphone², vivo continues to demonstrate a deep understanding of what today’s users truly need.

A Battery That Keeps Up With You – Decoding the Tech Behind

At the heart of the T4 5G is its standout feature—a 7300 mAh battery, built for the go-getters, streamers, gamers, and hustlers. This phone is crafted to last, so you don’t have to live tethered to a charging cable.

What makes this battery truly special isn’t just the size—it’s the technology behind it. The T4 5G will use BlueVolt battery anode materials and industry-leading third-generation silicon, which will boost energy density by 15.7% compared to its predecessor. That means more power, packed more efficiently, into a sleeker device.

The T4 5G’s battery will not heat up like many of your devices. Thanks to the Direct Drive Power Supply, which will ensure efficient power delivery while reducing heat buildup. This system supplies power directly to the phone and includes trickle charging, minimizing thermal consumption. This results in a cooler device even when gaming while charging, maintaining battery stability. Additionally, it reduces charge-discharge cycles, extending battery lifespan.

And technologies like Carbon Nanotube conduction, Electrode Reshaping, and Nano Cage Structure work quietly in the background to ensure battery health over time, minimizing degradation and making sure your phone performs like new, even after heavy usage.

Fast Charging, Slim Design, Zero Compromise

Big batteries often mean bulky phones—but not this time. The T4 5G’s Emerald Blaze edition will come in at just 0.789 cm thickness, making it India’s slimmest smartphone in this category¹.  This thoughtful design will ensure you don’t have to compromise on style or comfort while getting a long-lasting battery.

And when it’s finally time to recharge, vivo’s 90W FlashCharge technology will make sure you’re back in action in no time. It’s all about getting you powered up fast—so you can get back to creating, connecting, and living without interruptions.

With the T4 5G, vivo continues to bring innovation that listens to user needs—blending lasting battery life, sleek design, and quick charging into one smart, practical device.

Stay tuned—because this is  just the beginning of something revolutionary.
