The Echo Meter Touch module requires a data connection with a smartphone or tablet in order to work. Some devices support wireless charging, and we have generally had success using both wireless charging the Echo Meter Touch at the same time. We cannot guarantee this will work with every device that supports wireless charging.

There are several ways to reduce the amount of power your device uses:

• Before using the Echo Meter app, close all other apps that are running in the background.
  • On iOS, double-press the home button and swipe each app panel upwards to close it.
  • On Android, press the Recent Apps button and swipe each app panel away to close it.
• Lower the device's screen brightness.
• Once you start recording, press the sleep/wake button to turn off the device's screen while continuing to record.
• Rather than using the device's built-in GPS receiver, use an external GPS module paired via bluetooth.
