I think my iPhone SE has a ~7 Wh battery. It needs about 80% extra charge each day, which means its consumption is roughly 5.5 Wh per day or about 2 kWh/year.

I think my iPhone SE has a ~7 Wh battery. It needs about 80% extra charge each day, which means its consumption is roughly 5.5 Wh per day or about 2 kWh/year. At the previous 112 TWh/year ETH was using before the merge, that would be the equivalent of 56 billion iPhone SE's. Think about that. The energy usage of ETH's POW used the equivalent power of 50B smartphones.
