Yeah, battery life was never a problem. The Dexcom G4 battery lasted like seven months. I've heard of some people claim they can keep a sensor going a few month

Yeah, battery life was never a problem. The Dexcom G4 battery lasted like seven months. I've heard of some people claim they can keep a sensor going a few months, by restarting the transmitter, but they're definitely outliers. For most people biofilm builds up and the sensor data gets really noisy. Massaging the flesh around the sensor can help extend it. I typically go ~20 days per sensor.
