When the sonde was landed, it turned off. I was afraid a bit, because the last points was above the motorway, but i had a big luck. The sonde was turn left on the last few hundred meters, and landed on a fresh plowing.
The problem is the battery holder. When the sonde hit something with its side, the battery move to the side and bend the battery holder. As a result, the battery is disconnected.
The disconnected terminal:
I did some quick measurements:
The battery voltage is 3.006V after the flight, when the sonde is off.
If i turn on the sonde, the battery voltage is drops to 2.886V.
The off state current consumption is 1.25uA.
The average current consumption is 136.5mA with 3.085V supply voltage.
The current graph:
