How to approach it
Charging speed is set by negotiation: besides VBUS, the connector carries the identification lines (ACC, or CC on USB-C) and the data lines. The charger IC limits the current if it misreads the battery temperature or identification. The most common cause is the connector itself: dirt, worn pins or a non-genuine cable.
