I face almost the same situ now, running it for 5 mins in offline mode, results in 87% in c0 13% c4, no much of c2 or c3. this is after a complete reflash (rootfs+emmc), only conky was installed but not running. No abnormal cpu usage.

Is it normal that power to says that it ran for 30 mins when no time is defined, but if we define a time it'll add it to 30mins. eg 30 + 300 secs.

Any thoughts vi_?
