Battery quit pairing yet charges fine – DEWALT Tool Connect Review

My battery is just under two years old. I last had it on my older iPhone 5 and decided to connect it to my iPhone 6s Plus and it refuses to connect. I’ve searched and searched everywhere I cannot find any information on how to connect the battery to a new phone. Fair warning if you’re going to change phones you may have an issue
