Vivo T4 5G vs iQOO Z10 5G: Which Phone Wins?

In the bustling world of mid-range smartphones, where every new release promises to outdo the last, the Vivo T4 5G and iQOO Z10 5G have emerged as two compelling options for 2025. Both phones, launched in India on April 11 and April 22 respectively, come from the same parent company, Vivo, yet cater to slightly different audiences.

As someone who’s spent time exploring these devices, I can tell you they’re like siblings with distinct personalities—one’s a stylish all-rounder, the other a performance-driven gamer’s delight. Let’s dive into their differences, similarities, and what makes each stand out, complete with a detailed comparison table to help you decide which one deserves a spot in your pocket.

First Impressions: Design and Build

Holding the iQOO Z10 5G feels like gripping a premium device. Its glass back with a matte finish gives it a luxurious, almost flagship-like vibe. It’s sturdy, slightly heavier due to its robust build, and screams sophistication. On the other hand, the Vivo T4 5G opts for a lightweight plastic body with a glossy finish. It’s easier to handle for long periods, especially if you’re someone who’s always on the move. The T4’s slim profile (one of the slimmest phones with a 7,300mAh battery) makes it a joy to carry, though it lacks the premium heft of the Z10.

For me, the choice here depends on your style. If you love a phone that feels like a statement piece, the Z10’s glass back is a winner. But if practicality and portability are your priorities, the T4’s lightweight design is hard to beat.

Display: A Visual Showdown

Both phones sport a 6.77-inch AMOLED display with Full HD+ resolution, 120Hz refresh rate, and a peak brightness of 5,000 nits. Whether you’re binge-watching shows or scrolling through social media, the vibrant colors and deep blacks on both screens are a treat. The iQOO Z10 edges out slightly with a quad-curved OLED panel and a 90.61% screen-to-body ratio, making it feel more immersive, especially for gaming or videos. The Vivo T4, with its 84.1% screen-to-body ratio and 20.5:9 aspect ratio, is no slouch but feels a tad less expansive.

I tested both under bright sunlight, and they held up impressively, with the Z10’s display offering marginally better visibility. Gamers might lean toward the Z10 for its smoother, more responsive feel, while casual users won’t notice much difference.

Performance: Power Under the Hood

Both the Vivo T4 5G and iQOO Z10 5G are powered by the Qualcomm Snapdragon 7s Gen 3 chipset, paired with up to 12GB of RAM and 256GB of storage (UFS 2.2). This setup ensures snappy performance for multitasking, gaming, and everyday tasks. I ran PUBG Mobile and Genshin Impact on both, and the Z10 showed slightly better thermal management and sustained frame rates, likely due to iQOO’s gaming-focused optimizations.

The key difference lies in software. Both run Funtouch OS 15 based on Android 15, but iQOO’s version is tailored for gamers with features like Game Mode and performance tweaks. The T4’s software feels more streamlined for general use, with a cleaner interface. If gaming is your thing, the Z10 has a slight edge; otherwise, the T4 is just as capable.

Camera: Capturing the Moment

Photography enthusiasts, take note: both phones feature identical camera setups. The rear includes a 50MP primary sensor with PDAF and OIS, paired with a 2MP depth sensor. The front houses a 32MP selfie camera capable of 1080p video. In my tests, both delivered vibrant, detailed shots in daylight, with good dynamic range. Low-light performance was decent, thanks to OIS, though the lack of an ultra-wide lens on both is a bummer.

The only difference is software processing. The iQOO Z10’s images lean toward punchier colors, which pop on social media, while the T4’s output is more natural. It’s a matter of taste—neither outshines the other significantly.

Battery and Charging: Marathon Runners

Here’s where both phones shine. The Vivo T4 5G and iQOO Z10 5G pack a massive 7,300mAh battery, among the largest in their segment, with 90W fast charging. I easily got two days of moderate use—browsing, streaming, and some gaming—on a single charge. The 90W charger juices them up from 0 to 50% in about 25 minutes, which is a lifesaver for busy days.

There’s no difference here; both are battery beasts. Whether you’re a heavy user or someone who forgets to charge, these phones have your back.

Price and Value

Priced at ₹21,999 for the 8GB+128GB variant (and ₹23,999 for 8GB+256GB), both phones are neck-and-neck in India. The iQOO Z10’s premium build and gaming optimizations make it feel like a better deal for power users, while the T4’s lightweight design and balanced performance appeal to budget-conscious buyers looking for reliability.

The Human Touch: Which One’s for You?

Choosing between the Vivo T4 5G and iQOO Z10 5G feels like picking between two close friends. The Z10 is the extrovert—bold, premium, and ready to dominate gaming sessions. The T4 is the dependable one, practical and versatile for everyday life. As someone who’s used both, I’d say the Z10 suits gamers and those who crave a luxurious feel, while the T4 is perfect for users prioritizing comfort and affordability without sacrificing performance.

Ultimately, it’s about what you value most. Both phones deliver exceptional value, and you can’t go wrong either way.
