to pay for stuff, route finding, apps to call a taxi etc...
Do you always carry a spare battery pack with you, or would you always be close to a car anyway with a charger cable in it? Or your phone battery always lasts 24 hours+ no matter how intensively used the phone is.
Just wondering how people make sure the phone will always have enough charge in it, if you're super reliant on your phone. And if you carry a battery pack, how do you make sure that always has enough charge in it (and do you carry more than one spare cable in case cable goes faulty)
