Damn. I had to look up the SI prefix scale to make sure i got this right. 100 microwatts would be 0.1 miliwatts. If they truly do end up releasing a 1 watt version of this battery, it would be fucking perfect for meshtastic nodes. Currently, the most common radios used in those nodes transmit at 22 dBm, which is about 150 milliwatts. In client mute mode, the radio by itself transmits one packet every six to eight minutes on average. A 1W battery should constantly run the node without ever having to charge it or, even if not, only have to charge it extremely rarely. I'm not sure how long it takes to actually transmit a packet, but assuming it takes a minute per packet, which I think would be incredibly unlikely, then it would transmit seven times per hour if it transmitted every five minutes and would use about 21.4 milliwatts. As efficient as the NRF-52 chip is, I suspect it is the thing that's taking up most of the power.
