If your cellphone is an iPhone and the Life Proof case is the appropriate case for your phone, the hinged opening on the case and charging port on the phone will match.
I do not have an iPhone, but have an iPad and Macbook so am familiar with current Apple products that utilize lightning ports and cables. I have a Samsung cellphone with a Life Proof case. Case charger opening and phone port match exactly. Older iPhones may have utilized a different/larger connector like earlier iPads did. If that's the situation with your iPhone, I don't know if the Life Proof case matches.
