华为公布了鸿蒙 HarmonyOS 7 花粉 Beta 版的直连供电功能适配机型名单[1]。该功能在设备充电至生效电量时启动，通过直接向设备供电的方式降低发热，单次充电后自动关闭[1]。
目前，直连供电功能已适配 HUAWEI Pura 90 系列、HUAWEI Pura X Max 标准版以及 nova 16 系列等机型，其他机型正在推送中[1]。其中，nova 16 系列需要将游戏助手升级至 16.2.2.300 版本才能使用该功能[1]。直连供电是 HarmonyOS 7.0 版本新增的特性[1]。
HarmonyOS 7 花粉 Beta 版的报名于 7 月 28 日启动，随后开启推送[1]。系统包大小约为 10GB，部分机型超过 20GB[1]。
Huawei has revealed which devices will support the direct power supply feature in HarmonyOS 7 Flower Fan Beta version [1]. This new functionality, introduced in HarmonyOS 7.0, activates when the device reaches a specified charge level and delivers power directly to the device, thereby reducing heat generation during charging [1]. The feature automatically deactivates after each charging session [1].
The compatible devices include the Pura 90 series, Pura X Max (standard edition), and nova 16 series [1]. For the nova 16 series specifically, users must upgrade their Game Assistant to version 16.2.2.300 [1]. Huawei indicated that additional device models are currently receiving rollout support [1]. The HarmonyOS 7 Flower Fan Beta registration began on July 28, with system updates following shortly thereafter [1], with installation packages ranging from approximately 10GB to over 20GB on certain devices [1].
