Vivo X500 Pro Max could carry 8,000mAh or above battery, Xiaomi 18’s battery capacity also tipped
Chinese smartphone makers Vivo and Xiaomi are gearing up to raise battery capacities of their upcoming flagship smartphones, according to fresh leaks that surfaced over the weekend. As leaked earlier, Chinese tipster Smart Pikachu has reaffirmed that the Vivo X500 lineup will consist of four smartphones, while Digital Chat Station has revealed that the highest model in the series could come with an 8,000mAh-class battery. On the other hand, the Xiaomi 18 is expected to gain a major capacity boost over the Xiaomi 17.

Vivo X500 series expected to include four models
Over the last few days, a leak has been circulating on Weibo stating that the Vivo X500 series will comprise at least four models at launch, namely the Vivo X500e, X500, X500 Pro, and X500 Pro Max, courtesy of Smart Pikachu. Furthermore, just a few days earlier, DCS revealed the key specifications of the Vivo X500 Pro Max.
These include a 6.85-inch 2K LTPO display with 144Hz refresh rate, LPDDR6 RAM, and a high-end camera setup headlined by a 200MP periscope telephoto. It is said that the display will be sourced from BOE and feature large corners and symmetrical thin bezels. This is not the first time BOE will supply panels to Vivo, as the X300 series flaunted the BOE Q10+ displays. Coming back to Smart Pikachu’s information, the 8,000mAh on the X500 Pro Max will act as a significant upgrade over X300 Pro’s 6,510mAh battery, potentially resulting in far superior endurance.

In a reply to a comment, DCS mentioned that the 200MP periscope camera will utilise a 1/1.4-inch sensor, the same size as the one found in the Vivo X300 Pro, but further polished and refined. With the sensor already large enough, it makes sense for Vivo to continue optimising its imaging capabilities without altering the hardware much.
Xiaomi 18 to sport a 7,200mAh battery
When the Vivo X500 series’ model and battery information surfaced, DCS has revealed that the upcoming Xiaomi 18 could rock a 7,200mAh battery. If this information holds, the Xiaomi flagship will have 200mAh more battery than the Chinese variant of Xiaomi 17, and 870mAh more than the global variant.
Just like its predecessors, the Xiaomi 18 is likely to feature a compact 6.3-inch display; therefore, it’ll be a huge feat if the company manages to fit in such a large capacity in a small form factor. Apart from that, the device is said to pack a powerful Snapdragon 8 Elite Gen 6 chipset, a dual 200MP camera system (including a 3x periscope telephoto), and advanced features like ultrasonic fingerprint sensing and full IP-rated waterproofing.
Both leaks reflect a growing trend among Chinese brands: packing larger batteries into compact flagships while supporting high-refresh-rate displays and advanced cameras. Though still early leaks, the promise of multi-day battery life is exciting for power users. Those needing a phone soon may want to consider current models, as the new flagships are expected to command premium prices. Both the Vivo X500 series and Xiaomi 18 series are anticipated to launch around September 2026.
