My CIRQA lasted more than 10 days on a single charge
I think I finally figured out what was killing my CIRQA's battery life.
The biggest change was disabling automatic activity detection and completely turning off Pulse Ox (SpO2).
When I had Pulse Ox enabled, my CIRQA was barely getting 6–7 days of battery life. After disabling it completely, along with automatic activity detection, I got almost 15 days on a single charge.
One thing to keep in mind: I only recorded activities 5 times during those 15 days. It was an unusually inactive couple of weeks because of my work schedule and other commitments, so I barely had time to exercise.
I'm curious to see how much of a difference the activity tracking itself makes.
Starting this week, I'm going to try doing one activity every day and see how long the battery lasts with Pulse Ox and automatic activity detection still disabled.
I'll update this post once I have some results.
