We’re seeing a wave of extra-large battery phones. This next one is from vivo, the vivo T4.
The vivo T4 comes with a large 7,300mAh third-gen silicone-carbon battery with an 838Wh/L density. It managed to have this large battery while sporting an ultra-thin build that’s just 7.9mm thick and weighs 199g.

As per vivo, it lasts for up to 35 hours of YouTube streaming, 15 hours of gaming, and 17 hours of Instagram reels on a single charge.
It is paired with a 90W FlashCharge adapter, with a 1-50% charge only taking 33 minutes. Bypass Charging is also supported, sending power directly to the motherboard to minimize heat when gaming.

We have a Qualcomm Snapdragon 7s Gen 3 processor under the hood, paired with up to 12GB of RAM and 256GB of storage. A 6.77-inch AMOLED screen is on the front, with a 32-megapixel camera on top and a fingerprint scanner at the bottom.
A 50-megapixel main shooter is on the back, joined by a 2-megapixel depth sensor. It ships with Android 15-based FuntouchOS 15 operating system and will receive 2 Android upgrades and 3 years of security patches.

The vivo T4 is first available in India. The 8GB/128GB retails for INR21,999 (~Php14,600), 8GB/256GB for INR23,999 (~Php15,900), and 12GB/256GB for INR25,999 (~Php17,200).
