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?

[–] [email protected] 6 points 16 hours ago

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?

[–] [email protected] 4 points 9 hours ago (1 children)

In addition to the other reply, it helps align the tx/rx coils for higher efficiency

[–] [email protected] 1 points 8 hours ago

This makes sense with a higher power connection

[–] [email protected] 6 points 16 hours ago (1 children)

Because it means compatibility with magsafe accessories. So, you can attach magnetic powerbanks and other things to your phone.

[–] [email protected] 3 points 11 hours ago (1 children)

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.

[–] [email protected] 5 points 11 hours ago

Apple helped developed the QI2 wireless charging and magsafe is also a wireless charging standard.

That's nice although there is still zero adoption:(

[–] [email protected] 2 points 1 day ago (1 children)

Its not zero. HMD has launched a phone which is QI2 compatible and oneplus 13 also supports this standard

[–] [email protected] 3 points 20 hours ago (1 children)

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.

Samsung doesn't bring hardware upgrades until 2-3years later. They have stagnated and become more like apple.

[–] [email protected] 1 points 11 hours ago

Its not easy to make changes quickly when you have to then produce hundreds of millions of them.

[–] [email protected] 1 points 1 day ago (1 children)

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?

[–] [email protected] 9 points 1 day ago

It was always supposed to. Unfortunately, not everyone does a great job of implementing standards.
