The only thing I can suggest is run the phone from its battery. If you need to charge up a power pack or battery from the dynamo then recharge the phone from that. For a lithium battery try to keep it charged more than 70%. Running it until its is fully discharged reduces the number of times you can charge and discharge your phone.
Floating around on the shelf I have a USB device that takes two AA batteries, they can be rechargeable ones, and it will recharge a phone or tablet. I one I have is by Everready but I'm not sure if they still make them. Why are you using a dynamo to run the phone by the way?
