Battery built to last: How the vivo T4 can be your all-day companion

A closer look at the smartphone designed to power your daily life without interruptions.

With a 7,300 mAh battery, the vivo T4 is equipped to offer extended, uninterrupted service for long periods.

How many times do you pick up your phone each day? To call a friend, check an email, track your fitness, or binge your favorite show? Our smartphones are central to nearly everything we do. But as our dependence grows, so does the one constant anxiety — low battery. It's no surprise that battery life has become a top priority when choosing a new smartphone.

With the vivo T4, vivo addresses this need. According to vivo, this device is India's slimmest smartphone with a 7300 mAh battery—largest capacity available.

Recognising the consumers' need for a powerful and sustainable smartphone, vivo has introduced the T4 as the latest in its T series lineup, featuring India's highest-capacity battery to date, according to the company. The smartphone is designed to offer extended usage, enabling up to 15 hours of intensive gaming or 35.5 hours of continuous video playback.

Powerful battery in a lightweight design

With each successive iteration, vivo has been bringing new innovations in mobile battery technology, and delivering smartphones with larger power cells without sacrificing the sleek aesthetic appeal and robust performance that the brand is known for. The vivo T4 too keeps up with the aesthetic appeal of the phone and a bigger battery does not mean a heavier or bulkier smartphone. Despite the large battery, the phone maintains a slim profile (7.89 mm) and light weight (199 grams), which contributes to its portability and comfort during long usage.

To achieve this battery performance without making the phone bulky, vivo uses a combination of technologies. One of the key innovations is the use of Third-Generation Silicon-Carbon Anode Technology. Unlike traditional graphite, these materials allow for higher energy density in a compact space. Carbon Nanotubes — tiny tubular structures arranged in a honeycomb pattern — are also used to enhance the battery's energy storage and improve its long-term durability.

Additional technologies such as Electrode Reshaping Technology and the Nano Cage Structure further contribute to battery efficiency and lifespan. The reshaping process helps stabilise internal components, while the Nano Cage prevents material degradation, a common issue in high-capacity batteries. Together, these features are designed to offer consistent performance even after many charge cycles.

Non-stop performance across the day

The culmination of these advanced technologies gives you a smartphone with a worry-free battery life cased in a sleek and slim body frame, with an overall thickness of just 7.89 mm and weight of just 199 grams, ensuring a comfort of use, an ergonomic grip and effortless portability. This large battery of the vivo T4 comes in handy in various scenarios — imagine a world where your smartphone effortlessly keeps pace with your most demanding activities:
