According to the introduction, the battery replacement service involves replacing the battery with a new one of the same specifications, while the battery upgrade service involves replacing the existing battery with one of a larger capacity.
IT noticed that in addition to the Xiaomi 14 / 14 Pro, Xiaomi Civi 4, Pro, and REDMI K70 phones have also launched this service. The regular price is 189 yuan, but from October 1st to 7th, there is a 20% discount, making it 151.2 yuan after the discount.
Xiaomi Civi 4 Pro: 4700mAh → 4930mAh
REDMI K70: 5000mAh → 5220mAh
Extended reading shows that Xiaomi's battery upgrade service was first launched in 2026 for the Xiaomi 13 series, covering three models: Xiaomi 13, Xiaomi 13 Pro, and Xiaomi 13 Ultra. The regular price for the service is 189 yuan, which includes a battery upgrade fee of 149 yuan and a labor fee of 40 yuan. After the upgrade, the battery capacities of the three models are as follows: the Xiaomi 13's battery capacity increases from 4500mAh to 4850mAh, the Xiaomi 13 Pro's battery capacity increases from 4820mAh to 5361mAh, and the Xiaomi 13 Ultra's battery capacity increases from 5000mAh to 5500mAh.
According to the introduction, the battery used for the upgrade is a silicon anode high-energy density cell that shares the same origin as Xiaomi's Jinsha River battery, allowing for an increase in capacity while maintaining the same phone size. Since the new battery has a larger capacity, it will take slightly longer to fully charge once compared to the original battery when keeping the same charging power. In addition, due to differences in capacity specifications and charging management strategies between the old and new batteries, it is necessary to update the phone's system to a specified version before the upgrade to ensure compatibility and safety.
Among the two models mentioned in the text, Xiaomi Civi and Pro were released on March 21, 2024, and went on sale on March 26, 2024, featuring the first-generation Qualcomm Snapdragon 8s mobile platform; REDMI K70 was released on November 29, 2023, and is equipped with the second-generation Snapdragon 8 mobile platform.
This battery upgrade service is not currently available for the Xiaomi 14 Ultra. According to official information, the Xiaomi 14 Ultra is equipped with Xiaomi's first Jinsha River battery, and the corresponding upgrade service is expected to be launched in the second quarter of 2027.
