It appears there are roughly five power consumption modes for the GTM. It’d be useful to know what the nominal power draw is for each.
- “off, but connected to USB external power” (described as a speical low-power mode in the SDK docs)
- “on, relay mode” (supposedly lower than paired mode)
- “paired mode with partner device in range”
- “on, not in relay, no paired partner in range”
I’ve seen both #2 and #3 described as being sustained by the internal battery for 24 hours, implying 24.5mA. #2 is supposed to be notably lower. Surely someone (at GoTenna, if nowhere else) has actually measured these? #4 has been anecdotally described as being 2x #3, and that seems plausible. But I am trying to calculate power-budget tradeoffs, and having actual numbers for 2, 3 and 4 would make that a lot less wonky.
