Each of those peaks correspond to the sending of an advertising BLE package over the three advertising channels:
The idle power consumption between peaks is ~4.6 μA, that is similar to declared 4 μA declared in the datasheet for sleep consumption with all SRAM retention.

• PCB is labeled as iTag13-RSH V3-20250417. It's a very recent design.
I wanted to know it's power consumption so I connected it to my Nordic Power Profiler Kit II. During normal operation the average power consumption is 21 μA.

I have disassembled one of them to make a quick analysis of its main components:
This is the PCB out of the two-part encloser with the battery still attached.

In the past, tag locators compatible with Google Find Hub (aka Find My Device) were only available from a bunch of manufacturers and were somehow expensive (~25€), but in the last months I've seen some cheap tags on Aliexpress by RSH (under 4€).

Well, kind of. It started charging and the system works, but I have damaged one of the spring contacts with the buttons, I have lost one of the buttons. I cannot use the watch! 😅

Si preguntas a DeepSeek por temas comprometidos (para el régimen chino) del estilo de Tiananmen o los Uyghurs, te empieza a dar una respuesta para, de repente, cambiarla por un mensaje de:

Let's talk about something else."
