Battery reading while charging & power off #34

I have attached an on/off switch. I'm unable to get the battery reading when the device is turned off and charging. Here is the behavior:

  1. Not charging & turned on, IO4 reading is correct.
  2. Charging & turned on, IO4 reading is correct.
  3. Charging & turned OFF, IO4 reading shows full battery.

So it looks like IO4 gives me the charging voltage when turned off, not the battery voltage. I need to get the battery voltage so I can display the device charging.

How can I do this?

When charging, the charging voltage is obtained, and the battery voltage cannot be obtained.
