DURATION BATTERY FREE METER 2

Good I just acquired the free freestyle meter 2 before I had the 1, and I have been able to verify that the battery lasts little, I only use it at night since for the day I carry the application in the mobile, the case is that at 3 daysI already have to load it if someone happens too, the meter 1 lasted almost more than 10 days, and as I have in guarantee I do not know what to do
thank you

It is because of the alarms and because although it is constantly off it is working so that they sound.The same happens to me.
