Xiaomi's upcoming smartphone, the high-end Mi 10 Ultra, will reportedly be sporting "the first mass-produced 120W graphene battery".
Xiaomi claims the 4,500mAh graphene-based lithium-ion battery packs 1,000 times greater conductivity than traditional carbon black batteries. The brand was also quoted as saying that the battery remained at over 90% capacity after 800 charge and discharge cycles.
It was also said that Xiaomi implemented three cooling solutions - a graphene-copper sandwich for the chipset, RAM, storage, and modem; additional graphene sheet, combined with a copper cooling chamber with vapor underneath the front panel; and an additional highly-conductive film, sitting right between the optical fingerprint scanner and the OLED, helping to dissolve the heat across the 110 sq.cm display.
The use of graphene-based thermal management systems was also seen in markets like computers and gaming gear and in several of Huawei's smartphones and MatePad Pro 5G tablet.
