Linux笔记本运行Android Studio时内置USB设备功耗异常升高求助
Android Studio运行时内置USB设备(摄像头、指纹识别器)功耗异常
我是Linux新手,最近遇到一个问题:运行Android Studio(AS)时笔记本电池消耗明显加快。我知道AS本身会占用较多处理器和内存,但没想到内置USB设备的功耗也会上升——我根本没在AS里用摄像头和指纹识别器,但用powertop看到它们的功耗情况如下:
The battery reports a discharge rate of 9.48 W The energy consumed was 201 J The estimated remaining time is 4 hours, 15 minutes Summary: 2656.5 wakeups/second, 0.0 GPU ops/seconds, 0.0 VFS ops/sec and 49.1% CPU use Power est. Usage Events/s Category Description 6.18 W 25.5 pkts/s Device Network interface: wlp2s0 (ath11k_pci) 2.81 W 94.9% Device Display backlight 1.44 W 100.0% Device USB device: Integrated Camera (Generic) 138 mW 100.0% Device USB device: Goodix USB2.0 MISC (Goodix Technology Co., Ltd.)
我没有连接手机,也没使用模拟器,关闭AS后,powertop里就不再显示最后这两个USB设备的功耗条目。
想请教这是什么情况,为什么这些设备在AS运行时会出现功耗异常?我的Android Studio信息如下:
