If magnets are used to give the correct orientation, why not also have POGO pins or indentations next to the coil?
Case 1) the device only supports wireless charging (say because it's waterproof): business as usual
Case 2) the device also has conductive metal dots: the POGO pins can then charge the device much faster.
- user_7832 4y agoHonestly I am not sure why more devices don’t bother with pogo pins. It can provide close to the benefits of both wireless convenience, and wired efficiency together. My iPad and Amazfit watch are the only things I have that have pogo pins. (And yes they can get dirty etc but are also easy to clean. Not like USB ports don’t gunk up, or Qi doesn’t have issues either. Plus it’s very likely cheaper!)
- vlovich123 4y agoPOGO pins wouldn’t really impact waterproofing unless I’m missing something (similar to how you can have a USBC / lightning port on a waterproof phone). Is super the real reason is this would have limited value because: A) you have this already through cable charging B) it’s not clear it would meaningfully change the charging speed since you’d also need a communication standard (eg USB-PD) to negotiate the charge rate C) all of this is made moot by the fact that most people have a case on and don’t take their phone out of their case to put it on a Qi charger which negates the benefit. So basically cost and complexity for limited to no value. Of course maybe C is solvable by extending the pin through the case but I would think it would add cost to the case + maybe create some structural challenges negating the shock absorption.
