Hi! I have two XT, very close one to each other, at more or less the same distance from wifi and black box. They produce roughly the same amount of alarm recordings and I watch them live for roughly the same amount of time. I did put on both new lithium batteries from the same package at the same time. I had a low battery indication on one of them after maybe 2 months of use, and it got offline after a few days. The other one is ok. Now the only difference is that the one which stopped is quite near to a fm radio which I leave on all the time and it “listened” to music and talk 24/365. Can this justify the battery drain?
