Hello there, jimmy.
It seems you are wanting to know what's the best practice for charging the battery on your iPhone 6s. The following Knowledge Base article offers up some great information in regard to maximizing the performance of your iPhone's battery:

You can recharge the batteries any time you like, it does not hurt the battery (unless you let it drain 100%). With the old NiCads or NiMh batteries it did make a difference as they had a memory but with the Lithium Ion batteries in iPhones, there is no memory effect. This User Tip may help:
