iPad Pro 29W Fast charging tests and 3rd party adapters

Forget it's a piece of s**t. At 24% it stoped charging. It shows charging, after 2 seconds it stops charging, than again charging than stoped and so on. garbage.

I bought the same piece of junk.
It even managed to uncharge my iPad Pro.
I use the original USB-C cable from Apple.

I will return to sender...

By the way if you have a bank of america credit card they are having a reward where you get $50 for spending $15 or greater in two transactions at ATT. So i bought the 3m apple usb-c to Lightning cord twice. I hope it works, i will get them for free basically.

I wouldn't purchase both cords one after another because i think their system looks at both orders and puts them on hold, thinking it is an duplicate order.

Bought the same combo on amazon, how fast did it take you to charge your IPad 10.5 from dead to 100%? Mine took 2h 35 min in total.

I don’t know exactly, but it’s probably around the same as that. The wattage seems to drop linearly after 50%

Got quite a drop from 80/90% too. But that's normal so I've heard to protect the battery.

My other findings with airplane mode on are: 0-64% in 1 hour
0-80 in 84 mins. Roughly 1% per min.
So it seems to be on point with what other people are getting right?

I bit the bullet and got the 29W Offical Apple charger from John Lewis and the official 2m cable. A nice surprise when I got to the till, charger was the usual £49, but instead of £35 for the 2m cable, it was just £8.95. The chap said it was an ‘odment’ and they only stock the 1m now. So, I paid £58 instead of £84 for the pair which is a bit easier to swallow. It’s like night and day compared to the 12w included charger. Shame on you Apple for not including it in the first place!

Nice work :) and yes, I agree... should be in the box already!!

Can someone confirm for me that once the iPad Pro reaches 80% charged, both the 12w and 29w chargers would then charge at the same speed?

It took me approx 65 min to charge my iPad Pro 10.5 from 80-100% with the stock 12w charger. My Aukey 29w charger seems to charge slower than the 12w charger from the 80-90% mark for some reason
 
Darn, now I will have to sell off my Aukey powerbank and wall charger as they don't have USB C PD :( (Closest is a 5V 3A USB C port on the powerbank)

I will need QC 3.0 and normal 2.4A ports along with the USB C PD port though
 
On cable pricing...

Unless you value your time at $0 or you were handed an alternative choice, the time you spend researching a cheaper cable ends up costing you more than just buying the Apple one. You also save time on the backend should you ever need to take your product in for servicing as you can avoid the entire "I didn't use Apple products" line of questioning.

But hey, if your time really is worth $0 then I guess the search is valuable.

Hey, if people's time is worth more than $0 every second of the day people wouldn't be piddling around on MR or any other forum. I agree time is the most valuable commodity but it doesn't take hours to research peripherals and also can be done while waisting time somewhere else like in line at the store or waiting for a train/bus/plane, going to bed, etc.

Now the fact that you really need Apple's cable at this point does make doing a search pointless. But researching products in general is not a waste of time unless you spend all day looking for a $6 Lightning cable after you found a good $8 one.
 
Here's another option for those using the OEM/Apple 29w charger, and you need the longer USB-C to Lightning cord.... Because the 2m cord is $35, and impossible to find on sale, you can use the 1m cable, and get a ~$5-6 Apple OEM brick (duckhead) extension, which is at least 6ft. Now you have ~10ft, at a cheaper price than getting the 2m OEM/Apple USB-C to Lightning cord.

I have seen a few ex-Apple Genius employees claim that fast charging is not good for the device. One even made the claim that it causes charge cycles to be used up quicker than regular charging, decreasing the life of the battery. The latter statement is technically true in that fast charging will complete a charge cycle quicker than regular charging. That does not necessarily change how one uses their device though. For example, a user will likely go through the same number of charge cycles over the course of say a year whether that person is quick charging or charging normally. At least that is how I see it. Any input on this from anyone would be appreciated. Bottom line, is fast charging "bad" for our iPads? I think no, otherwise Apple would be unlikely to showcase this as a feature.

This is how I feel as well. Boils down to trust at the end of the day. Do you trust Apple engineering? I do. Conversely, we have Samsung.....

But jokes aside,
  • Apple releases features slowly usually because they want to get it right the first time
  • This was developed in conjunction with the USB-C PD standard. If the standard significantly affected battery life, why was it even developed in the first place? ref: practically all USB-C charging devices. Does that mean you should charge your USB-C MacBook Pro at 12W just to "extend battery life"? What about the Nintendo Switch
  • This isn't the first iteration of fast charging on the iPad Pro. I would think 2nd gen fast charging has probably ironed out whatever issues that may have been.

If said fast charging was not "smart", there might be some truth to the idea that it would be harming our iPPs. However, multiple tests discussed on these forums indicate that the charging voltage/amperage ("power") is greatly varied depending on what the current level of the battery is. It seems to me the most harmful situation would be trying to fast charge a full or nearly full battery at full power. It also seems to me that safeguards are in place to ensure that this never happens.

EDIT: According to standard battery theory - if I have understood what I've read here correctly - 29w fast charging of iPads Pro is not really "fast" charging, but closer to normal/standard* charging. The included 12w charger is actually "under" charging these batteries, which does no harm, but is slow.

EDIT 2: *commensurate with the battery's size/capacity

Does it matter that, for example, Ugreen CD127 USB-C charger has a rating 5v/3A instead of 5v/2.4A? Is it still safe?

Any comments on Ugreen as a power supply manufacturer?

I'm pretty sure the circuitry won't allow an illegal ampere rating to flow if it's not supported. It will just negotiate to charge at a slower speed instead. I've not heard of iPads going beyond 2.4A for any voltage, so it will probably just charge at 12W at the most.
 
Susurs said:
Aukey and Anker on the first page have 5v/3A as well.
Click to expand...

Yes but they support 15V/2A as well, so during electrical negotiation the higher power will eventually be used during the initial power adjustment, unless the iPad is already almost at max capacity, in which case 5V/some sub 1A electrical charging flow will be used instead.
[doublepost=1502920645][/doublepost]To better explain this - look carefully at the red line in @Nathan-K's post: https://forums.macrumors.com/thread...2-9-ipad-pro-29w.2015416/page-3#post-24364730 You can see the voltage slowly ramping up during the negotiation phase.
