Rest assured that Qi2 does require magnets, WPC clarifies

Summary

Qi2-certified phones all have magnets; no need to worry anymore about false rumors.

Neodymium magnets for Qi2 charging are small, taking up little space compared to induction coils.

Pressure applied to Android manufacturers can encourage magnetic compatibility with existing and future accessories.

Will I be able to charge a qi2 phone on an OG Qi charger?
- Yes, the opposite is also true. I know people who charge their Qi1 phones on Qi2 chargers, and you can even stick a metal ring on a phone case so that the Qi2 charger can attach.
What's the deal with magnets, are they supposed to replace the coil? Why are these reporters so excited about it?
- In addition to the other reply, it helps align the tx/rx coils for higher efficiency
  
  This makes sense with a higher power connection
- Because it means compatibility with magsafe accessories. So, you can attach magnetic powerbanks and other things to your phone.
  
  Oh so the magnet if for sticking the power bank to the phone. Okay. I have almost zero exposure to Apple devices so I thought Magsafe is just their name for wireless charging.
That's nice although there is still zero adoption:(
- Its not zero. HMD has launched a phone which is QI2 compatible and oneplus 13 also supports this standard
  
  Okay so not exactly zero, but until a heavy hitter like Samsung won't even consider, worldwide adoption is going to be low - their flagship just stuck with Qi 1, even though the standard existed for about two or three years at this point.
I had a wireless charger melt a few years back cause I had a chunk of metal in my phone case.

Does this new standard include safety checks for stuff like that?
- It was always supposed to. Unfortunately, not everyone does a great job of implementing standards.
