Yesterday afternoon I have left my Arduino running on a fresh Alkaline 9V battery (+ connected to Vin, - connected to GND). Today morning (16 hours later) the LCD display was no longer visible, and when I measured the volatage, I saw the battery was depleted to my surprise - its idle voltage was only 7 V.
My device is Arduino Uno with LCD 2x16 with LCD backlight and 2 DS18B20 sensors. Is it normal for such device to deplete 9V battery this quick?
I have read an answer to What are (or how do I use) the power saving options of the Arduino to extend battery life? question an answer to What are (or how do I use) the power saving options of the Arduino to extend battery life? question and I think what I see might be related to this, however I am not sure. If it is, is there some common schematics how to connect Arduino to be powered by a battery efficiently?
