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”
In: Technology
Well we do. The problem lies in the fact that different batteries have different capacities, different devices use different amounts for different tasks. This could be represented with regular units of electrical measurements, but for the average user this would mean little. The usage of percentages is a more readily understood concept by the general public hence it use in mainstream electronics.
