Redmi General Manager brags about the supposedly top-notch battery life of the Xiaomi Redmi K40

Redmi General Manager has taken to Weibo to tease the battery life of the upcoming Redmi K40. The company's next flagship smartphone is expected to feature a MediaTek Dimensity 1200 SoC, which would give it a leg up on the Dimensity 1000+ in the now-discontinued Redmi K30 Ultra. The Redmi K40 will supposedly adopt a 120 Hz OLED screen, too.

While high refresh rate displays typically eat through battery life, Weibing has teased that that may not be the case with the Redmi K40. While we do not know under what conditions the Redmi K40 achieved the battery life result shown below, Digital Chat Station claims that the device was running at 1080p, or 2,400 x 1,080 pixels to be precise.

Weibing revealed that the Redmi K40 had 64% battery life remaining after 10:30 hours of use, which MIUI projected would last the device a further 25 hours. Perhaps crucially, Weibing did not show the screen-on time that the device had achieved while being switched on for 10:30 hours. The quick and sharp declines on the battery graph suggest that the device had been used at short intervals though, with long periods of being left in standby.

Xiaomi has teased that the Redmi K40 series will start at CNY 2,999 (~US$462), but it is unknown in what form the series will arrive globally. We doubt that the Redmi K40 and Redmi K40 Pro will arrive as such in Europe, though. Xiaomi will, undoubtedly, release a Redmi K40 outside of China, but it will probably release the regular Redmi K40 and Redmi K40 Pro under its POCO or Mi brands in most markets, instead.
