An iPhone holds 7.45 Watt hours, so if you fully charge it every day it's ~2.8kWh / year. 20% power loss is 560 Wh/year. US electricity use is ~13 MWh per capita per year (let alone total energy use). I know it sounds wasteful, but it's very important to triage ways to conserve energy, otherwise you end up with things like the awful "unplug your phone chargers" campaign. |
