You have only proved your own pi survived > 5V once, not that all pi would.
Very true - but as long as I have a lucky Pi for the project - I'm fine with that
I imagine a few others will give it a go now and hopefully report in
Today - the Pi is still going after 12 hours!
Its down to 3.9V but still sending out 30 mins MQTT messages on mosquitto.org topic pizero4aa
And still flashing a LED
And I can still VNC into it and launch LX Terminal
So either today's set of batteries (which came out of same pack as yesterdays are a lot better or the official RPI white dongle draw much lower power than yesterdays RaLink
