We’ve just deployed some firmware changes to how devices behave when they are on battery.
In a nutshell, the devices only connect every 10 minutes now, which gives a massive boost to battery life since WiFi is the biggest consumer of battery. They still log data every minute , so you’ll still get the same amount of data, just don’t be spooked if you see “8 minutes ago” in the app for your latest data if your device is on battery. Rest assured that you’ll get 10 minutes worth of data the next time it connects.
If you have questions, suggestions, or comments, let me know here.
