Installed my first glucose sensor! Easy and painless, with no feeling that I'd been stabbed by a Pushpin of Health™ in the process.
I wonder if the variability of the #Dexcom #stelo sensor lifespan has to do with one's phone's proximity and power settings, and how quickly the sensor is paired after application.
The sensors are BTLE - they wake up and attempt to transmit data every 5 minutes. If the phone isn't nearby or paying attention, I wonder if it searches for longer?
Also, as soon as it's applied it connects to power, so I imagine it's in a fully online pairing mode until it connects to the app, that probably burns battery faster.
No idea if the actual sugar levels it measures might have some impact- if the reagent on the probe wears out the more sugar it reacts with? The "erratic readings followed by loss of connection" described in reviews suggests a low battery state though.
