Refer to LG V10 user manual https://support.t-mobile.com/docs/DOC-24222, There is Qi wireless charging function was integrated with your V10. After review LG official wireless compatibility tab to see complete compatibility information, you need an extra LG wireless charging case to replace the original back case.
It works by using inductive charging technology to allow your V10 to charge without connecting a charger. No longer will you have to search for your charger and orient it the correct way just to plug in your phone
You need to get a new back with the wireless charging antenna on it, or an antenna sticker for wireless charging. I got one from Amazon and have been using the Samsung charging pad and a LG brick. This is an example of a back with the charging sticker https://www.amazon.com/gp/aw/d/B017...ag=hawk-future-20&ascsubtag=UUacUvbUpU5670843. There are many others available.
