Not only can you take advantage of Nordic's advanced power states, but you can also put the device into a low power standby state. Laboratory measurements are putting that mode at about 2µA of current. 2µA! It also features a 3.3V Buck-Boost which helps get every mWh from your batteries as possible.
No batteries? No problem! Power your nRF9160 Thing Plus externally with a USB-C cable. Keep it on at all times for high availability scenarios.
Want to persist data? The nRF9160 Thing Plus has a 4MB external flash for storing data while offline. Using external flash with a filesystem like LitteFS and you'll have a project to recon with!
