On the road, switch off WiFi
Switch off the WiFi when on the road. Saves a lot of cellphone juice. Recipe is simple. Works in conjunction with you Automatic OBD2 device connected to your car. The moment you fire up your car engine WiFi on your device shuts off. Saves a lot of battery power when on long drives. Use it in conjunction with the other recipe of mine where the WiFi is turned on when the engine is shut down.
