JAKARTA - Vivo is reportedly testing a smartphone with a giant single-cell battery that can typically reach 12,000mAh. This leak comes from Weibo tipster, Digital Chat Station, who says the device is currently still in the internal testing phase.
According to information circulating, this device uses a 4.53V single-cell silicon battery with a capacity of 10,000mAh. However, the typical capacity is said to be in the range of 11,000mAh to 12,000mAh, with a small tolerance.
If true, this will be a significant leap even amid the trend of large batteries that have started to "normal" in the Chinese market.
In recent years, smartphone battery capacity has increased consistently, especially from Chinese manufacturers. If 5,000mAh was considered large, now the figure is practically the minimum standard. Devices with 7,000mAh to 8,000mAh batteries are increasingly common, and a number of brands such as Honor and Realme have released phones with 10,000mAh batteries.
Vivo's move, if true, would put it at the forefront of the endurance race.
The discussion also widened to competitors. When asked about Xiaomi's plans for a large-capacity phone, the same tipster said that such a device was still in the planning stage and would bring "all the necessary features." That is, Xiaomi is said to be considering a similar move, although there has been no final decision.
Meanwhile, for Vivo's main flagship line this year, the 9,000mAh capacity is said to be unlikely to be achieved. However, the sub-brand iQOO has the potential to present a device with a 9,000mAh battery.
Technically, the use of a silicon anode battery in a single-cell configuration is the key behind this capacity surge. Silicon technology allows for higher energy density than conventional graphite, so that capacity can be increased without making the device body too thick. The challenge is stability, charging cycles, and heat management - areas that are usually the focus of long testing before the product is actually released.
However, it's worth noting that this is still a rumor. The device with a typical capacity of 11,000-12,000mAh is still in the testing phase, so the launch schedule is not yet certain. Even if the testing goes smoothly, it will take time before this device actually enters the market.
But the direction of the industry is clear. When chipset performance starts to reach the point of "fast enough for everyone", differentiation now shifts to durability and efficiency. If 12,000mAh becomes a reality in a body that is still comfortable to hold, the new standard for smartphones could change again.
And if this trend continues, maybe the question "do you bring a charger?" will one day feel like a nostalgia of the small battery era.
