Lora rak button only lasts 2 days the battery

My button I charge and everything works for about 2 days. The specifications of the button says that the battery is for two years, is someone else having something similar happening? Thank you.

Hello @marcel
What settings you use? Please give us more information. Join mode , sleep, print screen from uplink and downlink data, etc.

Sorry for my English that is not very good. Use for join mode OTAA. I want him to sleep until one of the buttons is pressed. Simply send the information that was priced. So far it is like that, it only sends when I press, but the battery lasts only 2 days.

Thank you
