Earlier today, Chinese Weibo tech blogger, @DCS reveals some parameters of a new Xiaomi flagship smartphone. According to him, the Xiaomi flagship will come with a decent 4900 mAh battery and will support 120W super fast charging. He further reveals that like the Xiaomi 12 Pro, this new Xiaomi flagship also uses a single-cell solution. However, the latter has a larger battery capacity and theoretically longer battery life. Recall that the Xiaomi 12 Pro comes with a 4600 mAh battery capacity. Since there is no other Xiaomi flagship in development, this upcoming device is most likely the Xiaomi 12 Ultra.
From the report, one of the most important aspects of the Xiaomi 12 Ultra is the 4900 mAh battery with a built-in single cell. As we all know, on the Xiaomi 12 Pro, Xiaomi equipped it with the Surge P1 charging chip. With the support of the Surge P1 chip, Xiaomi 12 Pro has achieved a 120W fast charge. This is a high-power fast charge that was completely impossible for single-cell batteries in the past.
Not only that, the most significant advantage of single-cell compared to dual-cell is that it can save more space. It also has a larger capacity under the same volume and has more advantages for fuselage control. Now Xiaomi’s new flagship also adopts a single-cell solution. This means that the flagship may also use Xiaomi’s self-developed Surge P1 chip. According to speculations, this flagship may be the upcoming Xiaomi 12 Ultra
