Vivo is preparing to bring the Y31d Pro to Indonesia on April 13, 2026, and the device is already drawing attention for one clear reason: a 7,000mAh battery paired with 90W FlashCharge. The phone is positioned for users who spend long hours on their devices and need a model that can last through work, communication, entertainment, and travel without frequent charging.
The launch also signals Vivo’s push to strengthen its midrange lineup with a device that focuses on endurance and practical daily use. Beyond the battery system, the Y31d Pro adds durability claims, emergency power functions, and a 50MP AI camera, creating a package that targets active smartphone users in Indonesia.
A large battery for all-day use
The main highlight of the Vivo Y31d Pro is its 7,000mAh battery, one of the biggest capacities expected in its class. Such a large cell is meant to answer a common need among users who often move outside their homes and do not always have access to power outlets.
Vivo Indonesia says the phone is built for “non-stop” activities, a message that fits how modern users rely on smartphones for online meetings, navigation, digital payments, and video streaming. In that context, battery size is not just a spec, but a core selling point for daily reliability.
90W FlashCharge aims to reduce waiting time
A large battery means little if charging takes too long, and Vivo appears aware of that concern. The Y31d Pro uses 90W FlashCharge, which the company says can refill the battery from near empty to full in about 58 minutes.
That figure makes the device especially relevant for users who need quick top-ups between meetings, commutes, or field work. A fast-rising charging speed can matter as much as battery life itself, especially in the competitive midrange segment where convenience now influences buying decisions.
Emergency power features add practical value
The Y31d Pro also includes Battery Extender, a feature designed for low-power emergencies. Vivo says the phone can still handle basic calling when the battery drops below 1%, while around 10% battery can still support limited navigation or content viewing.
This kind of reserve mode can be useful for users who are often away from home for long periods. It gives the device an extra layer of dependability when power runs out at the worst possible moment.
Reverse charging expands everyday use
Another useful feature is reverse charging, which allows the Y31d Pro to act as a power source for other devices. That can include TWS earbuds or, in some situations, another phone that needs a small emergency boost.
For travelers, field workers, and students, reverse charging can make one smartphone more functional without carrying extra accessories. It turns the phone into a backup battery for smaller devices when needed.
Durability is part of the pitch
Vivo is also placing strong emphasis on durability, with IP68, IP69, and IP69+ ratings. These certifications suggest a higher level of protection against water and tougher environmental conditions than what is usually found in standard midrange phones.
The company says the device can survive immersion up to 1.5 meters for 30 minutes and continue working in temperatures as low as -10 degrees Celsius. Vivo also says the body uses Guardian Glass and has passed drop tests to improve resistance in daily use.

Camera support keeps it balanced
On the imaging side, the Y31d Pro comes with a 50MP AI main camera. The use of artificial intelligence should help improve photo results in different lighting conditions and simplify everyday photography for users who want a dependable camera without needing a premium device.
This makes the Y31d Pro more than just a battery-focused phone. It tries to combine endurance, speed, and basic imaging strength in one package, which is often the formula that works well in Indonesia’s highly competitive smartphone market.
The pre-order period is scheduled to begin on April 13, 2026, alongside the official launch in Indonesia. Vivo has not announced pricing or full availability details yet, but those updates are expected to follow through the company’s official channels as the release date gets closer.
