As Chazmo and Stefan have mentioned it is 'not usual' for smartphones to be charged from our ebikes' batteries. Here is one of the rare exceptions…

Bosch Kiox computer/display connecting smartphone to ebike's batteries:
- Charging symbol (lightning bolt at top right of iPhone).
- Mobile phone's charge level (alongside ebike's battery levels) on Bosch Kiox computer/display unit.
- Different leads connecting Kiox (ancient deprecated USB port) and iPhone (USB-C). Jumble of wires conveniently out of view!
After taking this photo I rode for about an hour and, as usual, recorded the event with the Ride with GPS app (map display on). Despite the obvious drain from running a GPS app, the iPhone's charge level rose from 61% to 85%.
Don't expect similar phone-charging from too many other ebike computer/displays (including Bosch).
Thanks for reading.
