About

How the watch is doing, on seven pages, as InfiniTime's SystemInfo screens show it: the system, the battery, memory, the bootloader, the hardware, the tasks and the licence. The battery page merges InfiniTime's BatteryInfo with PinetimeLite's charging and low battery screens.

Using it

• Swipe left for the next page and right to go back. The bar along the bottom shows which page is on show. A page too long for the screen scrolls up and down.
• The system page shows the firmware version and commit, the day it was built, its state, the uptime and why the watch last restarted.
• The state is Confirmed when the bootloader keeps the firmware, On trial after an update until something confirms it, and Rolled back when the last update never confirmed itself and the firmware before it came back. A phone writing the time or reading anything over Bluetooth confirms an update by itself, so the state is mostly Confirmed.
• While the firmware is on trial the page warns that any restart rolls back and offers two buttons, as InfiniTime's firmware validation screen does: Confirm keeps it, and Roll back restarts at once into the firmware before it.
• The battery page shows the charge, whether it is charging, full, discharging, low (15 % or less) or almost empty (5 % or less) in its own colour, and the voltage. Below 10 % off the charger it also says Charge now.
• While charging, the battery on the left fills up again and again.
• The watch opens it straight on the battery page when the charger is plugged in or out, or the charge goes low.
• The memory page shows the free storage, the free heap now and the least it has been since the watch started, how many allocations the heap refused, and how many times the stack overflowed into its guard, counted across restarts until the power goes.
• The bootloader page shows the bootloader's version and the day it was built. A bootloader older than the version record shows CRC and the start of its checksum instead, as the status page does, and one that cannot be read shows Unreadable.
• The hardware page shows the Bluetooth address, the external flash chip and its JEDEC ID, the touch panel's chip and firmware, and the accelerometer. A chip that never answered shows No answer.
• The tasks page lists the firmware's tasks: how many times each has run and its share of the time since the watch started (CPU).
• The licence page says BattleTime is free software under the GNU GPL, version 3 or later, with no warranty.
• The memory, hardware and tasks pages show the values as they were when the app opened.

Screens

The system page, where the app opens: the firmware version, build day, state, uptime and why the watch last restarted.

A firmware on trial, with the warning that any restart rolls back, and Confirm and Roll back.

The battery page, a swipe left, discharging at 87 %.

On the charger: the battery fills up from the charge again and again.

Fully charged, at 100 %.

Low at 9 %, with the warning to charge.

Critical, at 5 % or less, where it says Almost empty.

The memory page, the third: free storage and heap, the least free heap, refused allocations and stack overflows.

The bootloader page, with its version and build day.

The hardware page: the Bluetooth address, the flash chip, the touch panel and the accelerometer.

The tasks page: each task's runs and share of the time.

The licence page, the last.

With the companion app

The companion syncs the watch's battery log, the charge at the end of every six minutes and whether it was charging. The System plugin's page lists each of the last two weeks' days with its average, lowest and highest charge.
