Battery Drain for Connect IQ App??

Just curious. I rode with my new custom data field yesterday. It worked great! Thanks for the tips here. It changes the field's background based on power level thresholds over a 45 sec rolling avg, and in the label field includes instant power levels and the percent time not moving.

But the battery drained to 28% in about 6 hours! So I charged it back to 100% with an external power source, and then it drained to 82% in a little over 1.5 hours. Meaning I would only get about 9-10 hours out of it.

The backlight is off. I generally get 15+ hours on a full charge.

Does the use of a color data field, or just the extra computation for the custom metrics, cause a much faster battery drain?

Thanks! I included a screen shot.
  • I don't think it's due to data field etc. Because CPU frequency, calculation amount etc. is probably fixed to a level that won't let the CPU calculate without power constraints.
    I think there should be another reason. Is BT on but phone BT off? Continuous BT searching takes a lot of battery power. Or try restarting and check it again...
