To my own experience, you'd better to get one or two spare battery fully charged and put it in your bag.
Extended battery is too bulky for me to put it into my pocket, and make my phone look weird.
You may just buy a external power bank or just buy one or two spare battery. That works great for me. Hope it helps.
