As you can see on the attachement, I've got a battery voltage icon on the top bar, an vechicle info app and a electric meter connected directly to the battery.

The top bar icon shows 11.8V
The vechicle info app shows 12.25V (it's not updating automatically, it updates on app startup)
Electric meter show 12.29V

Why there are different values? Why the top bar icon show a much lover value?

Hi,

The voltage displayed on the top of the car screen is the voltage detected from the chip inside the car stereo. The voltage displayed by the vechicle info app is from the car driving computer data. Both voltages are correct.

Best Regards,
