Boot Logs

引導日誌記錄設備的開機和停機。

Boot Logs logs your device's boots (and shutdowns), a.k.a. when was your device powered on and off.

Using Boot Logs, you can:

* Review the logs

* Sort by boot date or downtime (ascending or descending)

* Filter logs by date: display only logs from last year, last month, last week, last 3 days, last 2 days and today (there is also an option to display all)

* View your device's current uptime (time since last boot)

Boot Logs is useful when:

* You want statistics of how much time it takes your device to reboot (a.k.a. "downtime")

* You turn your phone off for a meeting or a conference, and after you turn it on you want to know how long you were unavailable

* Device is suspected to be out-of-order (unexpected shutdowns, which sometimes cannot be tracked by the app, while normal shutdowns can)

* You run out of battery and want to know how long you were unavailable

* You like reviewing logs and statistics in general

Note: Boot Logs cannot retroactively show logs, but only starts logging upon installation.
