== Battery tests ==
The amount of time the device will work from internal battery depends on the battery health, how often the device saves/sends information to the server, external peripherals connected to the device and the results may also differ depending on firmware used.
For general comparison purpose, and to see what results can be achieved, you can refer to the following internal test results in different modes and sending frequencies:
