So now that 11.2 is officially released, we can all get USB power meters like omegis83 did and let's start collecting some data!

Here is the one I ordered: https://www.amazon.com/gp/product/B01D9Y6ZFW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I purchased chargers from Pleson and Seneo that claim to support fast charging. I also briefly had the Mophie which I returned because it was too fickle in terms of placement and working with an Apple case.

I'm curious to determine the various charge outputs for these when using Apple 10W/12W adapters in addition to connecting directly to a MacBook. I'll post my results when I receive the meter.

You're only measuring the wattage coming out of the USB wall charger, not from the wireless coils charging the phone. Also, if Apple has restricted which wireless chargers it will accept 7.5W from, you still won't know anything for certain. Only by measuring how fast the phone charges, ideally from 0%, will you know if fast charging is occurring. Unlike Samsung, Apple has not provided an indicator on the phone itself, which would be most helpful.

I currently have this Qi charger that supports 7.5W output.

I have it plugged into the back of my LG monitor via a USB 3.0 port. Does anyone know if I'm getting the full 7.5W output or do I need some higher wattage wall adapter instead?

Think as long as it supports that watts then it should work fine. You able to test it out time wise when charging?

I'm going to see how much power (in watts) the phone is drawing so from this you can infer. I'm not measuring charge time. I want to know how much power is being drawn by the phone to determine if other chargers outside of the Apple approved chargers support 7.5w.

That would be great to know! I just don’t see how the meter you provided a link to will be able to do that. Also, remember that the power draw decreases as the battery gets closer to being full.

I’ve conceded that the only way to know for sure is to buy one of the endorsed chargers and compare it to the $21 model I got from Amazon. So this afternoon I picked up the Belkin from an Apple store and if I don’t see an appreciable difference, I’ll return it.

I'd like to know this too. I have one of those (the first one) and the LED is still blue when I put my X with 11.2 on it.

I don't have the unit yet so I can't confirm but here is a picture someone posted of the meter. It does exactly what i'm expecting. It shows power draw in watts from a connected phone. This is the info I'm after.

Oh, ok . Thanks so much for clarifying that. I didn’t realize it went between the power source and the phone. Unfortunately, my new concern is that Apple specifically states that if the lightning port of the phone is being used, then wireless charging won’t function. But it’s still worth a try. Lack of clarification from Apple has made us all detectives in trying to figure out what is exactly going on. Good luck.

 

[floridonet]

Right, so in the case of the wireless chargers that have USB (Type A) it would connect like this:
Power Adapter -> USB power meter -> Wireless Charger -> Phone

(effectively, the USB meter is sandwiched in between the power adapter and the wireless charger. lighting connector not used as in the picture above.)

You said you bought the Belkin which has a proprietary charger that may not be USB (Type A) so this meter would not work. However, for the Seneo/Pleson/RavPower/Anker and the likes which use standard USB to connect to their power supply, then the meter should read and give me volts/amps/watts.

We should start a master thread for this so we can keep an easy reference, up to date list of which chargers support faster charging speeds.

Couldn’t that meter go between the power source and the wireless charging pad?

Hey, you’re just a little confused on how it all works, this is common don’t worry. It’s just a Voltimeter/power meter that has a USB connection to make things nice and convenient instead of using terminal leads. It plugs directly into the charger, then the USB end of the charger plugs into the female port of the meter. You’re incorrect about the nature of how/what it’s measuring tbc. Until you plug a device into the charger it’s connected to, it reads zero, unlike voltage, whatever it is that’s being powered, a phone in this case, draws only as much amperage as it needs/can/never more. The simplest way to think of it is with a simpler device like a radio, lets say it calls for a 9 volt 500 milliampere power source with a positive polarity, if you use a power source with too much voltage it will fry the radio immediately. If you use a 9v 3,000ma power supply though, it will still only draw 500ma, and as with the phone, the amperage won’t be drawn until the device is connected/powered on.

TL;DR the power meters work, are accurate enough for our purposes, and there’s no issues with knowing whether or not what it’s reading is actually being used by the phone, it is. When buying one just make sure it supports a range of voltages and amperages and not just 5V, as unlike previous iPhones the new ones charge at a range of voltages between 5 and I think around 13v or so at 2-3amps, as defined by USD PD specs, I wish they’d have been more aggressive frankly as it could charge much faster via USB C PD if they wanted it to. Anyhow Most meters on the market should be suitable though.

You can access it by hard pressing on the brightness in the CC. this will give you a quick toggle to night shift

I HAD NO IDEA! THANK YOU SO MUCH! Yes, I used caps because I'm so happy! Thank yoU!

What's the point of wireless charging if it requires additional hardware, charges at half the speed of a conventional charger, and still requires you to place your phone in a specific location like a normal cable?

Someone sell me on this.

Yeah, the TV remote will never take off and benefit users.

I would like to but I simply can’t, my wife has a wireless charger and she is always putting my phone on it. To check something I have to pick it up or make sure it does not move. If I need to interact I have to stop charging and pick up the phone. Not good for battery life. On my cable I don’t have to worry about it. Maybe if it stuck to my phone like the Apple Watch, but it does not so I don’t see the purpose.

Perfect point my tv remote is on a wireless charger but I can’t use it and charge at the same time. Same with a phone. Like that stupid Samsung commercial showing the guy listening to music with the dongles while she has her phone on the wireless charger. At least he is using his phone while she is stuck waiting for the charge to finish. Wireless charging is like the electric car. Great until you need a charge now you are waiting until it is finished before you can use it for its intended purpose. Until wireless charging can be free from the wire or contact pad it’s a waste.

I was told once that microwave does destroy electronics! But I guess that is a myth.........
[doublepost=1510642021][/doublepost]

Can I ask, what is it with the racing to charge it as fast as possible? Don't most people charge their devices overnight?

For me, it's the solution to the problem of discovering 15 mins before going out, that my phone is at 2%. I've been very happy with my iPhone X battery life so far though, hasn't been a problem.

Do what I did

get this samsung one...can be used for standing up or flat

this is the best wireless charging pad to me..I want one that stands up when I go bed personally

Buying a USB Digital Tester ($17.99) has changed my opinions about charging. Not long after getting my iPad Pro 12.9", I invested in the Apple 29 watt USB-C charging block and an Apple USB-C to Lightning cable. It just doesn't get any better than that for the charging the iPad. Is an expensive cable better than a cheap one? Is name brand better than generic? There are a lot of variables.

In the below two pictures, I used my Anker 40 watt 5-port (inducing USB-C) ($39.80) to supply the power in both tests. Then using a Joto 3.1 USB-C to Lightning cable ($11.99) that I picked up on Amazon, I tested charging on my iPhone X. The results were 5.09 volts at 1.03 amps which comes to 5.24 watts. Then I tested generic Qi wireless charger ($10.50) that I also got on Amazon. It shows 5.08 volts at 1.43 amps which comes to 7.26 watts. This is a big difference in charging time. In this case, USB-C isn't always better than USB Contactless.

USB-C charging will be the same as USB-A unless you have a USB-C PD (Power Delivery) charger and a compatible cable.

I've tried 3 different USB-C Lightning generic cables to compare them with Apple cable. I was using a "generic" USB-C PD 40W charger (don't remember the brand).
all generic cables charged my phone from 20% to 70% at the same speed as my regular USB-A cable and 2.1w charger.
but with Apple's USB-C cable, it charged my phone significantly faster. I see also the same thing with my Aukly cheap car charger that has USB-C PD... it charges my phone faster with Apple's cable.

So what I’m gathering from this is any wireless charger that puts out 10w will charge at 7.5w AS LONG AS the wall charger has the correct output and QI 3.0 QC support. This means Apple just controls how much watts max the phone will accept to charge at and it’s not a proprietary thing only certain fast chargers are “certified” for or have built in. Is this correct?

Yes, the wall brick is important. If you plug a 7.5w wireless charger to the small 5w brick your iPhone came with, it won’t charge at 7.5w. I haven’t tried a 10 or 12w iPad brick to see how that does because my wireless charger came with the QI 3.0 outlet, so they may work properly..
