Running GPS, 4G/5G data, and maximum screen brightness consumes circa 12W of power. Standard 10W chargers result in a net negative power draw (battery drain).
To keep a positive net charge during intensive navigation, use a USB-C PD source of at least ~20W — typically a PD car charger in the vehicle, or a ≥20W PD wall charger when parked/at home. Legacy USB-A ~10W adapters usually cannot outpace Maps + GPS + bright screen draw.
Input power is below instantaneous load. The UI shows a charge path is connected; it does not guarantee net-positive watts.
Usually yes for phones. Extreme heat, wireless charging, hotspot, and max brightness can still push load higher — then use a higher-watt PD source or reduce screen load.
In the vehicle use a PD car charger. At home/parked, a ≥20W PD wall charger is fine. Match the cable to the port.
