Apple Still Working to Perfect Wireless Charging Technology for 'iPhone 8'

- Start date
- Sort by reaction score
So far there is not a single wireless charging solution that is really satisfying, for a start devices become next to unusable when sitting on their charger (a wired charging phone I can hold and use). And I don't think there is any hope for the return of the 3.5 headphone jack, or even a floppy disk drive.

You hold your phone all night and don't sleep? You're the exception since most find the convenience refreshing like not having to deal with wires in and out of the car.

I would be very angry if the only benefit to a proprietary system would be it would charge 2X as fast. You do know there are things like Cota Ossia who are working at wireless charging from 30 feet away.
And of course I would be mad at such an incremental benefit. Qi I came out 4 years ago? Best thing they could do in 4 years is twice as fast (in the hypothetical scenario)? That's horrid!
Cars are already coming with Qi, and so many other products such as furniture. Wouldn't they want to work with the standards and get it better? The only scenario Apple should go it alone if they have developed something that leap aheads the competition and the standard.
I would say if they did what you said in your scenario, they really did miss the opportunity to make life better through technology as Tim claims he wants to do. Instead he is holding back tech and breakthrough technologies so Apple can add more dollars to there coffers while giving their customers sub-par products. Maybe that's why IOs is losing so much market share to Android, and entry level wearables are taking over the smart wearables market, and the chinese market is drifting away.
I'm not saying they should adopt Qi, but if they have a tech that is only slightly better, then their R&D has failed. Better to go use Cota Ossia and really a transformative product.
When I sleep I put it on the dock, that takes me less than a second. And what you call wireless requires a wire, so what is your point? ........... Yep there is no point

Wireless charging is always easier and quicker especially at night when it's darker. Don't bother arguing when you're wrong.

How is it quicker? You are wrong yet again. It is interesting that your concept suggests that wireless (which in itself is not wireless) is faster charging when it is dark. Don't bother replying when you are wrong!

are you buys actually battling if wireless charging such as Qi faster? It is, but it's just convenient but only an incrementally. It's still better than not having it.
My friend made me an amazing wood stand for the kitchen that has a Qi charging pad. It's so nice to drop my partners samsung on there while cooking. Shame Apple doesn't have that.
I do agree with apple that charging pads are only limited in functionality, and hopefully they have something in the works similar to Cota Ossia. i have lost so much faith in Apple though that they can pull anything off. So maybe Samsung will give us the next leap in wireless charging

Perfecting? It's an inductive charger. Apple isn't perfecting anything, they just realize that a segment of their user base will upgrade every iteration, so they're starting to dole out significant tech upgrades in smaller and smaller increments.

After thinking about it for a while, I think that having to rest the iPhone on a charging pad is negligibly different than having to plug it in. It's still stuck in that spot if you want it to charge.
I hope they are able to figure out a way to do it like WiTricity. You can have the power transmitter nearby, and as soon as the phone is in range, it begins to charge. I'd imagine the closer it is to the source, the faster it'll charge.
That would be the reason to implement wireless charging. Otherwise it's basically pointless. You can then just have a bunch of transmitters around your house and walk around while it charges.

sure they are - you could even run an AM radio just by the power it receives from the antenna. see: https://en.m.wikipedia.org/wiki/Foxhole_radio
the differences are in the wavelength (and power).

Wireless charging is more convenient than a cable.
However, it will never be quicker.
There is a built in inefficiency of using coils to send and receive energy by wireless means.
The cable is the fasted way to charge a rechargeable battery.
Previous devices, e.g. RFID badges and Pet Chip IDs, did not use a battery or require operation for any extended lengths of time. They only needed a minimum power up time and operate for a few seconds to be useful.
However, wireless charging is convenient at the expense of efficiency.
I would bet these Apple wireless chargers would be better used with the Apple watch that has a smaller battery and less power hungry devices.

From the Review:
The Cota "base station requires between 300 and 500 watts, it distributes as little as one watt of that stored energy over the course of a day."

This quote shows how inefficient wireless charging really is at a distance.
The efficiency is a function of the inverse square of the separation distance.
To get any sort of efficiency, the base and receiver need to be adjacent each other.
Otherwise, a cable is the most efficient and quickest way to charge a rechargeable battery.

A more modern example is the RFID badges people use for entry to secured buildings.
The badges have no battery but a coil to receive the RF energy and signal. They are powered up by electromagnetic waves (RF energy and signal) transmitted by a coil at the entry site of the building.
You missed one thing the iPhone can't do like the note 7, keep you warm at night.

I have some different stats on Cota. See below:
But that's not the point. The point is 4 years later and unless Apple's wireless charging is significantly better than QI, than it really shows it's not a leader in technology under Tim Cook. Anyways, it's all hypothetical at this point. I am excited for Wattup, Cota, Ubeam (if it actually works) or any other wireless charging standard. I agreed with Apple's critique that the benefits of Qi are minimal, but it's still better than nothing. And if they turn around and offer something similar to Qi, than I would be very disgusted with Apple for another flipflop.
Anyways, here is some more info on cota. I would like to see some independent testing though. Companies always exaggerate or pull can pull a VW. And hopefully it will be safe to use around kids.
http://spectrum.ieee.org/energywise...promises-to-enable-the-internet-of-everything
Cota's transmitter uses about 8 watts to deliver 1 watt of power to a device. This is not end-to-end efficiency; Ossia says that including all the necessary conversions and computing and LEDs and stuff, a Cota transmitter will probably use a total of 60-70 watts to charge 4-5 devices remotely at 1 watt each. That 8:1 ratio is the significant one, though, because that's the measure of the efficiency of the wireless power delivery technique itself... Ossia points out that if you use its system to charge something like a AA battery, it would be orders of magnitude more efficient and cost effective than buying even a single disposable A

I was responding to only the poster talking about Qi. I did mention real wireless charging similar to Cota in a previous post. I am really hoping that Apple goes this route of charging a device just by simply being in the room and not having to place it down on a surface.

I've said the same thing. They could probably have left the headphone jack in this model, but why surround next years full redesign with the controversy if it can be preempted in this way?
Apple have been very smart with this year's iPhone.
People are quick to jump and shout "Apple's doomed! No innovation, the phone looks like last years again!"
When really it's Apple deciding to take all the heat this year, on a phone that they're maybe not expecting to sell in the normal volume. Hopefully so that next years phone won't receive any of the same criticisms.

I'm really tired of fiddling with cables when I go to sleep. I also use Lifeproof, so if I wouldn't need to open the lid every day, it would be much more trustworthy. Also, most of the connectors are too big for Lifeproof. I also usually forget to reconnect the device, when I need to use it in the middle of charging.

Yay, probably even slimmer iPhone with no ports at all. You either transfer data through iCloud or you don't transfer it at all and you'll end up buying those pucks for home, car, office, summer cottage and whatever else (and probably keeping a few in your bag just in case) but luckily they're only $150 each. I'm so looking forward to what they "innovate" next. Possibly a dongle that hooks up to a dongle that hooks up to a dongle! I'm disappointed if the puck doesn't have any dongles you can attach to it.
