I seem to be having trouble charging my cel phione in my IS350. When plugged into the upper plug in the center console the charging seems to be on/off (I hear the phone beep every time the current is restored) but the battery level never increases. It just stays at whatever it was when I plugged it in.
Is that a Lexus 'feature"?

=================================
My karma just ran over your dogma
Current Hers: '24 Lexus ES350 Lux
Current Mine: '23 IS350 F Sport AWD

 

Bad cable?

 

Mine charges my phone all the way (if time allows for it). If I leave for a drive say an hour drive, even running GPS the whole time, usually by the time I get to my destination, my phone is fully charged.

 

I had a similar issue in my 23 IS350. I ended up getting a new cable (even though I was using the brand new Lexus provided charging cable) and the problem has resolved for now. As far as charging, I have a Pixel 8 and when I connect I get a "charging" notification vs "charging rapidly" when I use a wall charger. It can be frustrating but at least it functions properly now.
