NEW DELHI: vivo Y31t 5G supports a maximum of 44W charging through its supplied standard charger, rather than a constant 44W throughout a charging session. vivo identifies that adapter as 11V/4A and says the phone adjusts charging power dynamically. The same official instructions require a fully dry USB port before charging or connecting another device.

Price as of 1 November 2026, 00:34 IST. The price above is the named version displayed in vivo's India phone catalogue. It is included to identify the configuration, rather than present a complete range of Y31t prices or a bank-linked offer.
What the supplied adapter actually establishes
The product page gives the adapter's electrical rating and calls 44W the maximum supported charging power. The parameter page separately lists the charger and cable among the box contents. Taken together, those details establish that a standard charging setup is included, without requiring an assumption about a separately purchased adapter.
They do not establish that every Type-C charger provides the same result. The connector shape identifies the physical connection; the published charging ceiling belongs to the supported system. An untested replacement adapter cannot be assigned the standard adapter's performance merely because its cable fits.
vivo's wording also leaves no basis for converting the wattage into a fixed full-charge time. Its parameter footnote says actual power is adjusted according to electrical output, external factors and use. A charging session can therefore involve changing power, and the top figure is not a minute-by-minute promise.
The dry-port instruction still applies to an IP-rated phone
The Y31t's protection ratings sit alongside a clear charging condition. Its parameter footnote says the USB port must be fully dry before charging or connecting devices. It also says not to use a heat source such as a hair dryer to dry the phone. These are the manufacturer's specific handling instructions for this model.
This is particularly relevant because the same phone advertises wet-hand touch, water and dust ejection, and an underwater photography mode. Those features can make the device sound ready for immediate use after exposure to water. The charging instruction creates a separate boundary: an available camera mode or a responsive touchscreen does not confirm that the port is ready for a cable.
The official documentation also says resistance can decline through normal wear and that damage from liquid immersion is outside warranty cover. The protection label should therefore be read with the handling conditions printed below it, rather than used as permission to ignore them.
Runtime claims describe different tasks
The product page publishes separate playback and navigation figures. Its laboratory notes distinguish screen-off music listening over Bluetooth from navigation with the screen and sound in use. The useful point is the test arrangement: the published numbers describe particular tasks, not a combined day of travel, calls, camera use and messaging.
The phone's hardware reinforces that need for a specific reading. It uses a Snapdragon 4 Gen 2 processor and a 6.75-inch LCD with a 1608 x 720 resolution and up to 120Hz refresh rate. Those details describe this Y31t, rather than every vivo phone carrying a similarly large battery.
For a commuter switching between navigation and calls, the practical question is how those activities overlap. Adding a laboratory navigation duration to a separate playback duration would not create a valid estimate. Our vivo T5e vs T5x 5G: Rs 13,999 and Rs 27,999 compared provides the separate background on capacity labels.
Readers comparing other endurance-focused models can consult our Typical vs rated battery capacity: what the mAh on your phone page really means. For a different charging feature, our vivo phone price list India: Rs 13,999 to Rs 2,19,999 for T5e to X Fold6 covers separate hardware. Neither report supplies a charging time for the Y31t.
