Why haven’t we managed to develop an easily-quantifiable unit for ‘how much energy something has left’ in rechargeable devices? For example “oh man, that phone call just cost me 5 Whatevers of phone battery”

I am sorry, may I introduce you to the mAh aka milli-Ampere.Hour?
Although there’s catch, it’s a unit of charge and not energy. You need to multiply it with the voltage to get the energy, but we do use mAh or Ah (which is essentially C – Coulomb) for determining battery usage.
What are you doing while buying phones and power banks without having knowledge of the mighty mAh?
