The short answer: not in a form you can use
Android has no built-in screen that lists your earlier restarts.
Some phones can show how long they have been running since the last start, but that number resets with every restart and the earlier ones are gone. Technical logs exist for developers, but they are short-lived and not meant for everyday use.
That makes it hard to answer simple questions: When did this phone last restart? How often does it restart? Did that restart I asked for actually happen?
Troubleshooting
Confirm whether a restart really happened, and when.
Patterns
Spot a phone that restarts unexpectedly, or one that never does.
Shared devices
See at a glance when a shared or kiosk device was last restarted.
How to keep a reboot history on Android
RebootMonitor was built to fill exactly this gap.
- It detects every restart automatically and records the date and time.
- The history is kept for up to 12 months, with a monthly heatmap you can tap day by day.
- Everything stays on your device. There is no account, no cloud storage, no analytics and no tracking.
The history builds up from the moment RebootMonitor is installed. It cannot list restarts that happened before that.
