I am ditching my "real" camera for an upcoming trip to Spain. I will be using my Pixel 3A smartphone exclusively for photos. With my old camera, I used to take 200 to 300 photos in a day, with one extra spare. I intend to buy a power pack, but I'm trying to figure out how much extra capacity (and weight) I need to carry.
I could just sit my living room and keep snapping and counting photos until my phone battery dies. However, that is not very realistic. There's a big difference between doing that and walking around using your phone in real life, taking photos, viewing them, using Google searches, reading about attractions, checking GPS and maps etc. on the go.
So how many photos can you take on your smartphone before your battery dies?
