Beneath a shared foundation of 5G, dual SIM, NFC, USB-C, and Wi-Fi 5, the Y300t pulls ahead in several connectivity areas. Its Bluetooth 5.4 is a substantial generational leap over the Y300i's Bluetooth 4.2, translating to better range, more stable connections, lower power consumption, and improved support for modern wireless accessories. The Y300t also adds a microSD card slot — absent on the Y300i — which is a meaningful practical advantage, allowing users to expand beyond the built-in 512GB or swap storage between devices.
The cellular speed gap is equally notable. Both support 5G, but the Y300t's upload speed reaches 3270 Mbits/s versus the Y300i's 900 Mbits/s — more than three times faster. For users who frequently upload large files, stream live video, or use cloud backup heavily, that difference is tangible. Download speeds also favor the Y300t at 3270 Mbits/s compared to 2500 Mbits/s. On sensors, the Y300t gains a gyroscope — useful for gaming, augmented reality, and accurate motion-based navigation — while the Y300i counters with an infrared sensor, handy for using the phone as a universal remote for TVs and appliances.
The Vivo Y300t holds a clear overall advantage in this category. The Bluetooth upgrade, expandable storage, and faster upload speeds are broadly useful improvements. The Y300i's infrared blaster is a niche but convenient feature that the Y300t lacks, but it does not offset the Y300t's wider connectivity gains for most users.
