I have just been out mapping, and suddenly realized that both of my Xiaomi Yi had shut off. They had been running for about 30 minutes using the ash script that takes a photo, sleeps for 1 sec and starts over. I started them and they worked fine. Then they shut off a little later. I started them and they worked fine, then one shut off later. There was plenty of battery.
Has anyone experienced this?
Last Sunday I drove for about 3 hours without any issue. They got extra power from a power bank with 3 outlets.
