Tracy, do you where a Dexcom? If you do, don’t take it out after it “dies.” Just tell it you put a new sensor in, even if you didn’t, and it will start over again. I usually get another week’s worth out of it.
I use the minimed and can rarley get more than 8 days . after the first 3 days I do just tell it new sensor but then after the next 3 days it needs charged .
