> I am already on the "no SoMe and digital minimalism"-wave
I'm curious, what does "no SoMe" mean? I tried to search but not having luck figuring out what it means.
To respond to your question though, I've dealt with this in the past and the biggest thing that I try to focus on is, "What do I want to excel at working on?" In the past, I've had numerous activities (work, side projects, family/friends) going on at any given time and would rarely say "No" if people brought new opportunities to me. After operating like that for a while, I came to the realization that by having so many activities I was effectively putting minimal effort into most of them. Personally, I don't like giving something only partial attention due to decrease in quality, so when I realized that I was not really giving all these activities the attention I felt they deserved I decided to cut back. I went through all the activities I had going on and decided which ones I wanted to keep for some time.
Something else that might also help is a prioritized list of what you care about. I feel the exercise of going through and really thinking about what you care most about will help determine what you should focus on to avoid burnout
The last thing I can think of is taking things towards the bottom of the list (assuming they are small activities) and rotate them. As an example, I rotate my personal research, analyzing stocks/crypto, and playing video games. They are all things I enjoy but I can't do them all in the same day/week without feeling burnt out.
Wireless charging can't be used through the front glass of a phone because it needs to have a receiving (Rx) coil and not cause electrical interference with the parts between the receiving and transmitting coils by the magnetic flux produced by wireless charging.
If you look at the bottom of page 4 of this PDF document (numbered page 11 if it were printed), https://www.mouser.com/pdfDocs/TI-Designing-a-Qi-compliant-r..., you can see a picture (Figure 8) that shows the construction of wireless charging coils for phones. The Rx portion would be inside the phone. Notice that there is a part titled "Rx Shield". The Rx Shield is to protect components of the phone above it.
Figure 5 (on page 2 of the document) has a picture that shows the magnetic flux density graphed. The fields produced are in the low mT range, so parts need to be able to handle it without heating or interference and boards will need to have appropriate filtering, if you wanted to charge through the front glass.
