Faster charger for iPhone XS

[MacUse-R]

So these included 5 Watt chargers is not charging the Xs particularly fast, so at how many watts maximum can the iPhone Xs charge (safely)?

And how many watts is even possible from a charger that uses a normal USB-A port, is it up to maximum 10 or 12 Watts, or how many watts can these chargers charge at?

I have understood that to be able to use higher watt chargers one needs to use a charger with a USB-C port and a USB-C to Lightning cable.

Also about wireless charging, how many watts can the iPhone Xs charge at, is it 7.5 Watts or 10 Watts?

Wireless 7.5w (confirmed)
Wired 18w I think (USB-C)
Wired 12w USB non type-C

Okay so 7.5 watts on the wireless, I think they should have made it 10 Watt at least.

I think I have read it somewhere that people are using like 48 watt chargers on the new iPhones, but maybe the iPhones cannot utilize more than 18 watts anyway?

That is correct. even if you use the 87 watt charger the iPhone will only use 18w.

That is correct. even if you use the 87 watt charger the iPhone will only use 18w.

Okay thanks, then I guess I have to buy a 18 Watt charger and a USB-C to Lightning cable?

Since I guess normal USB-A chargers is not available in 18 Watts?
I wonder whats the maximum wattage the normal USB chargers are available in?

If you want to charge your iPhone XS as fast as possible either buy the Apple 18W USB-C charger and an Apple USB-C to Lightning cable, or one of these (I use the following below) as the blades fold in and make it great for travel. Don't forget to buy a USB-C to Lightning cable also (1ft or 2ft).

Thanks I will check those out.

Read these before you decide (1, 2, 3) whether certain options are worth it.

The smaller batteries in iPhones don't see as much of a benefit from fast charging as the large ones in iPads.

Get an iPad charger if you don't have USB-C ports on your Mac. Charges almost as fast, it's a lot cheaper plus it's OEM.

Thanks for the info.
But i´m wondering how these USB-C chargers can charge the iPhone at 18 Watt (I think that was the maximum amperage with which the new iPhones can be charged, am I right?)
Since the USB-C specs says that it can charge at up to 3 Amps at 5V, thats not 18 Watts I guess? Or does the iPhone charge at 9 volts and 2 Amps when it uses the fast charge, or how does it work when they say it can charge at up to 18 Watts? Or am I thinking this thing the wrong way?

I'm using my 30w Anker brick with an Apple usb-c to lightning cable. I'll have to go through my box of "gauges" and pull out the meter to see how much power it's getting during the charge. I'll have to discharge the batter though, so I'll play some Rush Rally 3, while stream link to elgato. That'll get the battery down rather quick lol.

USB-C power delivery is not limited to 5V. If I remember correctly it does 9V at 2 amps. With the Anker PowerPort5+ USB-C or the Apple 61W MacBook Pro charger.
Connected to a MacBook Pro USB-C port it peaks at 12W.

So you mean that the iPhone Xs can charge at more than 5 Volt?

Since if the iPhone can only charge at 5 Volts and the USB-C can do maximum 3A at 5V then thats not more than 15 Watts, or maybe I have understood it wrong?

Yes also I wanted to measure the watt and amperage with my USB amp meter, but my meter has no Lightning ports and no USB-C ports, so that was not possible.
I guess I have to buy one of these USB-C amp meters

But what I have noticed from these standard USB power bricks that claims to be 2.1 Amps they still only charge at around 0.86 Amps, sometimes they can peak at around 1.12 Amps for a split second.

And the 1A power bricks charges at only around 0.45 Amps.

USB meter is great to monitor things.

That’s what I get from the SmartBattery Case for the XS with a X inside at 68%

That’s from the XS Max at 73%
Each one is picking its prefered voltage. Same USB-C Lightning cable and same Anker PowerPort 5+ USB-C.

Interesting, so the iPhones can charge at even 15 Volts. But I notice that its charging at around 9-10 Watts even though its a fast charger. Is it maybe because its up at 73 % and the charging slows down a bit at higher percentages, even though I thought that the slow down shouldn't happen until after it reaches 80 % ?

What meter are you using?

 

[lostOzone]

It’s a Jokitech bought on Amazon

14.751w with the SmartBattery case at 43%

Thanks for the info, I bought one myself a week ago from UK Amazon, if it only showed up.
I bought the red one with color display, but I noticed it only works in one direction as opposed to some other ones which can be connected both ways. I should have bought the yellow one UM34C which has both USB-C, USB-A and micro USB as well as Bluetooth.
If it shows up I will be doing some measurements myself, I´m interested to know with how many watts my original Apple USB-C to Lightning cable as well as my third party fast charger charges with?

 

[MacUse-R]

Hmm, strange, I measured the fast charge from my iPhone XS with my Apple USB-C to lightning cable and a third party 30W USB-C fast charger with PD 2.0 (Power delivery 2.0).

The phone battery was at 33% when I started charging, in the first minute or so the phone charged at between 17-19 Watts, so isn't the maximum possible charge 18 Watts on the iPhone XS, yet it charged with over 19 Watts?

Also after a minute or so of charging it went down and charged with only around 13-14 Watts.

So im a bit surprised of the way it was charging, don't know if it is the charger, even though the charger is rated at 30 Watts, or if it is the phone that decides with how many watts it is charging?

But wait a minute....did the person in the previous post got his iPhone to charge at 15 Volts, mine charged at 9.1 Volts, so how do I get my iPhone XS to charge at 15 Volts? My charger is surely able to charge at 15 Volts, yet it charged at 9 volts?
