My kids transmitters get flaky after about 3 weeks, and I didn’t think you could reset an expired sensor on the G6 the way you could with the G5?
Should be possible with xDrip. Using the G5 still, so no real life experience.
Some sensors get noisy sooner than the others. I noticed they work longer during the winter when its cooler. Last one worked for 4 weeks quite good, but in the summer they stopped working in less than two weeks.
I realized I wrote weeks - the transmitter is good for 3 months and gets flaky in the last couple weeks.
I found some pictures of someone replacing the battery on the transmitter of a G6. This is.... not really practical. [1]
What would be interesting is if you could pull out the internals and 3D print a new enclosure that had an actual user serviceable battery.

The transmitter has a counter inside and will stop working after a certain day count. xDrip has a feature where one can reset the counter back to zero and I've been using them at least six months with no trouble.
Without changing the battery? Are you using G5 or G6?
I can understand why the sensor will expire, but why does the transmitter expire? Shouldn’t it just require changing a battery?
The problem with Dexcom is the price. A sensor should be replaced every week and costs 80€, the transmitter turns off after three months and costs between 300-400€. If you understand what you're doing, you can easily extend the sensor lifetime to 3-5 weeks and transmitter to 6-8 months.
My take to this is, every T1 deserves a Dexcom system from the insurance. It easily saves your life and makes the control much easier.
