You shouldn’t need to do that anymore, batteries are much larger and chipsets are more efficient than when removable batteries were the norm. But even if you do need to charge, that’s why fast charging exists.
How do you charge the 2nd battery? Do you charge it slowly when home and keep it as spare while you use your main battery and wait for it to charge to full.
Remember when you too some spare AA batteries with you for your Gameboy/Walkman/Discman so that you didn’t run out of juice in the back seat of your parents suburban on the way to grandma’s?
There used to be external chargers. I’m not speaking Nokia times, I had a Xiaomi phablet with Android 5 or 6 with one of these. Just a frame for the battery with an USB input.
I have a Fairphone with swappable battery, I keep one charged at 80% in case I need a quick reload of my phone. And after I used it, I recharge it in the phone and swap back to the empty one to also recharge it.
Carrying a spare battery is much more compact than a power bank and charging cable though. Or even a wall adapter and charging cable, which also requires an outlet.

In which you’d need a power bank and cable that youre carrying if you don’t want to be tethered to an outlet (which may or may not be available.)
Seems a second battery is just a better option.
