Thanks, cheers from Mexico!!!

Hello and good day saitron. Thank you for reaching out and for the inquiry. I am sorry to say that we do not recommend charging the DJI Osmo Pocket using the Samsung S10+.  Actually, there is a  possibility that this process will work, however, since it's not yet optimized by DJI we cannot guaranteed the stability of the said process when in use. We highly suggest you use the compatible charging device to charge your DJI Osmo Pocket for compatibility and reliability proposes and to avoid any issues or problems. Thank you.

Unless your phone can OUTPUT power, then it won't work - most smartphones do not output power to other devices.
It would be easier, and safer, to use a portable battery pack.
I personally use this one, works perfect:
