FP 6 - Qi2 (Wireless charging and Magnets)

I really would like to use my ordered FP6 with wireless charging and magsafe. The convenience of both in combination is just awesome.

We know, that the backpanel can be 3D printed and therefore edited to contain magnets.
Is there even a connectior inside, that the Fairphone company could provide a Qi2 module?

I would totally pay 50 bucks for this module with a colour fitting magnet backpanel.

FP intentionally doesn’t support these inefficient and therefore env unfriendly technologies.

Well, I guess it‘s not so simple.

Wireless is more ineffizient.

Magnet aligned qi2 is not as inefficient as the ‚classic‘ wireless chargers.

See ifixits analysis:

The upsides are user convenience and therefore a higher acceptance, less wear on usb (which leads to not having to replace the port during the overaverage lifetime of a Fairphone).

With an optional qi2 kit this would lead to the customer‘s choice: Convenience with less efficiency costs.

Maybe add up 20-30 Bucks to the kit to directly invest into a renewable energy power plant. This would enable to cover the energy loses of wireless charging with a measurable long term net plus.

Magnetic USB adapters achieving this are readily available.

Those magnetic USB C adaptors do not really solve the issue.

Without data transfer (or USB compliance in the first place) they are an annoyance when adding or removing files on my phone.

It‘s „well meant, but inferior designed“. And you would need to buy special cable for each aliexpress-vendor.

And its not at all a solution to „phone is held in place by magnets AND charged wirelessly“

There are magnetic USB C adaptors capable of data.

Data transfer is no problem as such.
USB-OTG would be, if needed.

Those adapters work as intended for a number of users here, while others are wearing out their ports :person_shrugging: .

No. You can just buy adapters to use with existing cables.

Yes. And I wish you success in getting this option.

According to iFixit’s testing, wireless charging requires 30-100% more energy. I wouldn’t consider this “more efficient” if you consider that you usually charge your phone daily. Also the batteries get much hotter, causing a lot of wear and tear on them.

Now that I think about it, if Qi2 use Magsafe anyway to snap the phone in place, why not use Pogo-pin-contacts or something? It might be not that clean or whatever but that would solve both problems. Probably will never happen but the idea is kinda cool I think :smiley:

Every device with pogo pins I had broke down exactly because of these pins. They’re the opposite of durable and reliable.

I wonder how we got here… my issue was “is it even possbile to retrofit qi2 by the Fairphone company”

results so far.

  • wireless bad.
  • I should do something different with highly proprietary non-USB-standard parts and waggly adaptors
  • no data isn’t my problem (yes it is), I’ll just need another adaptor for a task I didn’t ask for.

Sounds like late 00s classic internet forums. I just miss personal insults so far…

Regarding the waggly USB-C adaptors: There is already a standard for easy “place your phone and charge it”. Well established on the market and highly appreciated by the consumers. the USB-C magnet adaptors come in various different incompatible vaiants from dubious weekly changing vendors and solve basically just one issue (port wear) while implementing more than they solve: The Compatibility is quastionable at best, spare parts should be expexted to be available after more than half a year, most models don’t deliver data, those which do were evaluated pretty weak in this point, and it doesn’t hold the phone at all.

btw efficiency. I just ran the numbers based on the ifixit test. Over an estimated battery lifetime (~800 cycles) the net loss of a magnet centered wireless charging is about 4kWh (just over 1 kWh a year). Far from nothing, but way less than anyone of us could easly save otherwise. Just add one (!) additional day home office instead of commuting. Or compensate with a barely noteable increased price buying this piece of tech,

You should just ask them directly…

However, back to the first answer to your question

Btw: that can be considered an insult…

Fair point :smiley: still, there might be durable alternatives.

You named the thread in a misleading way. The topic seems to be about Qi2, not about charging-contacts inside the phone. You probably should call it “Are there charging contacts in FP6” or something like that.

Every device with pogo pins I had broke down exactly because of these pins.

There are much more robust spring-loaded contacts, as seen e.g. in wireless electric toothbrushes, rechargeable remote controls etc. – yes those contacts are bigger than Pogo pins, but you need only 2 of them, and there is plenty of space on a MagSafe holder or similar.

Another issue is the rotation and the contact surface on the phone side. One of the 2 contacts would need to be ring-shaped, and both contacts need to be rather clean and non-corroded. But the phone SW can easily detect a bad contact and ask the user to quickly wipe the phone backside, or just to rotate the phone a few times while attached to the holder.

All-in-all quite feasible and definitely worth requesting for FP7 !

my issue was “is it even possbile to retrofit qi2 by the Fairphone company”

There are several older threads about wireless charging, where the policy, the reasoning, and the technical aspects were discussed. Unfortunately, there is currently no such option, neither official nor through (meaningful) DIY.

The efficiency argument of FP is understandable, even though nowadays we often have ecologically “free” green solar power, but certainly that is not always available.

I’ve given up on magnetic cables because of practical issues, and because the “dongle” part that is permanently plugged into the phone is usually protruding, increasing the risk of mechanical damage when the phone falls or bumps. I try to get through the day without charging, and plugging in once per day is fine. I rarely use USB for data, which leaves only the situation every now and then when using the phone for navigation in the car. For this, a convenient apple-like solution would be nice, but it is certainly not essential to me.

I would like to add to the efficiency argument that I now encountered a weird edgecase where it actually would come in handy: We have a bluetti power station we dump excess solar power into that we generate. It would be very convenient to simply “sip up” that power by putting the phones on top of the station, which features an integrated wireless charger. Way better and easier than playing cable-jokey all the time. And since this is actual excess power, it simply would not get used much otherwise. I rather use it and waste 50% of it for inefficient charging than not using it. I could never stomach wireless charging for everyday charging needs given the crazy inefficiencies, but making green energy easy to use seems like a good unexpected use for wireless charging. Kind of a surprising niche I discovered for myself at least…
