I have really leaned into using the built-in Tesla software for everything. I honestly don’t have to pay much attention to my phone battery since it last so long (IPhone 13 Pro Max… I regularly do overnight trips without even getting my charger out). That said, if I recall, on even most of my shorter road trips I have always arrived with 100% phone battery.
Of note, my wife’s IPhone 12 Mini only charges if she places it on the pad upside down. Still, between the small phone battery and her constant use (social media is a big part of her business’s success), she effectively goes through its battery 2+ Times a day. Thus, the charging pad is NOT a good fit for her in the passenger seat.
