  • I mean I already wrote this out in reply to another comment but by their own numbers on the site announcing this they say that all phones combined yearly consume ~ 5.2 TWh, that’s 0.2% of the EU’s total anual consumption of 2.7PWh. They expect to reduce the power consumption by 20% (which I find questionable but ok) by 2030, reducing the consumption by 1.1TWh, thats just 0.04% of the total consumption. It really doesn’t matter that much. And as for your comment, laptops are already also extremely efficient, so it’s not like their power consumption is that significant either.

    For context, a day’s charge of a phone is equal to running a typical 2kW heater for 1 minute, a years worth of charge is equal to running it for 6 hours. I like the label and don’t think it’s a bad addition, I just feel that that information could have been replaced with more useful stuff (like how ethically sourced it was or how long it will be supported for), the energy efficiency feels more like doing it just so it looks the same as the other ratings without much purpose for it.


  • I was about to comment how this number doesn’t make sense, but reading the article they mention the power savings for phones specifically is actually 2.2TWh per year, which might be realistic. The rest of the 14 TWh comes from landline phones (2.2TWh) and energy used to produce phones that would be saved (8.1 TWh) from the lifetime extension measures, that aren’t even related to the power efficiency of phones and won’t take place in the EU.

    However, even these numbers are overinflated when you take into account they’re using a PEF factor of 1.9, meaning they multiply the actual power usage by 1.9 to adjust for stuff like power transfer losses (only 5-10%) and the inefficiency of generating power from e.g. fossil fuels (because e.g. petroleum might only convert 40% of its potential energy to electricity), but when people typically talk about power usage they’re talking about the actual amount of electricity that needs to be generated, not this abstract representation of it, meaning that e.g. phone electricity savings are actually only 1.1TWh-1.2TWh.





  • I mean, there are some who will be willing to do that, but the vast majority of average people won’t pay for something if a free version exists (like WhatsApp)

    Edit: Ok I just Googled it and apparently their operational costs are less than 1$ per user per year which is far less than I expected. That’s way more sustainable in that case, possibly even through just donations.


  • I see a lot of people saying it’s time to switch to Signal, and I mean I agree in principle, it’s my main messaging app, but I don’t see how it can scale. It runs off of donations and the only reason it’s still functioning is because the users that are there are above averagely passionate about it and willing to donate. If it became the defacto messaging app I fear that there is no way they would be capable of financing that level of traffic.
