The vivo T4R 5G and vivo Y400 5G make different trade-offs: the T4R lists a Dimensity 7400 processor and a larger display, while the Y400 lists a bigger battery and faster rated charging. In vivo India Store listings retrieved for this comparison, the T4R was also less expensive at the comparable 8GB+128GB and 8GB+256GB capacities. Those prices can change, and specifications alone do not prove which phone performs better in everyday use.

Which one is faster?
The T4R lists a MediaTek Dimensity 7400 5G processor; the Y400 lists a Snapdragon 4 Gen 2. On the stated hardware alone, the T4R is the more performance-oriented choice. That does not establish a measured difference in app speed, gaming performance, heat, or sustained workloads: no independent head-to-head test is available in the cited sources.

Battery capacity and charging: what the numbers say
The Y400 has the larger typical battery capacity at 6000 mAh, versus 5700 mAh for the T4R. It also lists 90 W rated charging, compared with 44 W for the T4R. These figures do not establish which phone lasts longer in real use or how long either takes to charge; actual results depend on usage and charging conditions, and the cited sources provide no comparable endurance or charging-time test.
Camera hardware and durability ratings
The T4R lists a 50 MP Sony OIS main rear camera alongside a 2 MP bokeh camera; the Y400 lists a 50 MP main camera and a 2 MP camera. Both list a 32 MP front camera. Megapixel counts and the T4R’s stated optical image stabilization do not establish which phone takes better photos or video. The manufacturer lists IP68 and IP69 ratings for both models; these ratings should not be read as a guarantee against all water damage.

- Consider the Y400 if its listed 6000 mAh typical battery and 90 W rated charging matter more to you than the T4R’s larger display or lower observed listing prices.
- Compare the exact variant before paying if you need a particular memory and storage combination. The T4R listing surfaced a 12GB+256GB configuration; the Y400 configurations surfaced here are 8GB+128GB and 8GB+256GB.
