Ondrej Holzman Many eyes missed this fact, but last week Apple presented a very important product for the large iPad Pro. At first glance, there is nothing special about the new USB-C/Lightning cable, but when you use it with a 29W USB-C adapter, you get much faster charging.
It is in the large iPad Pro, introduced last fall, that the possibility of fast charging is built in. But in the classic package, you will find insufficient equipment for an almost 13-inch tablet. The standard 12W adapter may be good for charging iPhones faster, but it's not enough for a giant iPad.
After all, many users complain about very slow charging when using the iPad Pro. Among them is Federico Viticci from Mac Stories, which uses a large iPad as its sole and primary computer. First introduced for the 12-inch MacBook, the above-mentioned more powerful adapter and cable was therefore purchased immediately after the last keynote and conducted a series of detailed tests to see how well the faster charging works.
He immediately felt the noticeably faster increase in percentages in the upper right corner, however, he wanted to get more accurate data, which was shown by a special application that cannot be found in the App Store due to restrictions. And the results were clear.
From zero to 80 percent the large iPad Pro with a 12W adapter charges in 3,5 hours. But if you connect it via USB-C to a 29W adapter, you will reach the same goal in 1 hour and 33 minutes.
Federico tested it in several modes (see chart) and the more powerful adapter, which comes with the extra cable, was always at least half as fast. In addition, unlike a weaker charger, the powerful iPad Pro was able to charge (and actually add percentages) while in use, not just idle.
The differences are therefore quite fundamental and the investment of 2 crowns (for 29W USB-C adapter a meter cable), or 2 crowns, if you want more cable a meter longer, it really makes sense here if you use the iPad Pro really actively and can't just rely on overnight charging.
Considering what changes using a stronger adapter brings, we can only hope that Apple starts to include this accessory as standard. Finally, we point out that only the larger iPad Pro really has faster charging. The newly introduced smaller version has not yet.
A complete analysis of the charging speed by Federico Viticci, who also describes why he measured charging from 0 to 80 percent, what application he used or how a stronger adapter is detected, can be found on MacStories.
So the battery will die that much sooner :-D
Otherwise it won't give me "They include Federico Viticci of MacStories, who uses a large iPad as his only and primary computer."
Fact? Am I the only one who finds this product placement of paid journalists beyond ridiculous after all these years? Apple will release a tablet with a bigger price tag and add "PRO", with the only change being that you can draw on it. And suddenly everyone's emphasizing how it's their _primary_ and _only_ computer. So the pen (and an additional one) was probably the only thing missing from the iPad to a full-fledged computer. And now for Little Red Riding Hood please.
Federico Viticci has been using an iPad as his primary computer for a few years now (sometime since the second and third generations, I'm guessing) because he was battling cancer and needed to work in a hospital. He couldn't have a MacBook with him at the time, so he reached for an iPad. I don't know anyone who uses an iPad like that. All his actions are automated, he uses dozens of applications for different scripts, task sequences, etc... It's definitely worth getting to know his story, what he did and that Apple only noticed him sometime last year :-) I recommend, for example, this https://www.macstories.net/stories/working-on-the-ipad-one-year-later-still-my-favorite-computer/
I have to admit, I didn't know the name of the gentleman, so thanks for the link. His case is probably very specific in many respects, as you yourself write.
However, my reaction is not aimed at him, but rather at the general flood of reviews that "coincidentally" exactly copy Apple's current marketing rhetoric. While a casual user has been able to use the iPad as a computer replacement for several years, the iPad Pro has changed practically nothing.
On the contrary, I think that it does not completely copy Apple's rhetoric. Apple says this is the "ultimate PC replacement," but so far, few people actually use it that way. The situation is changing quite quickly, but especially during the presentation of the large iPad Pro last fall, journalists were able to give a much better narrative in their texts about what kind of product it actually is and how to use it. A lot of people who tested it admitted that iOS can already do a lot, but they still can't imagine the iPad as a main computer. Those who actually use it like Federico are so far I think only a few. But more and more follow him.
The computer is always assumed to have a hw keyboard. The iPad is basically considered a device without an external keyboard. Unfortunately, without it, even an ordinary typewriter cannot replace it. Why? Because iOS doesn't allow it. Although he easily could.
To me, the funniest thing about this "replacing computers with tablets" is that in order to make it somewhat usable for work, it actually goes back to the laptop, which handles all of this a long time ago and better. What's the point of all the casting then? The wheel is being reinvented. All kinds of keyboards and strange flip cases with a few positions are dealt with, while I can firmly put the laptop at any angle and since time immemorial. It solves the strangely limited display of multiple applications next to each other on the mobile OS, while on the laptop I can already move the windows freely as I like. Etc. etc…
I don't think it should destroy the battery in any major way. Apple monitors these things and does not allow them if it is not beneficial ;-). By the way, both of my parents can easily exchange the iPad for their desktop computer, because they can read emails, surf the web, and play movies :-). On top of all that, it saves electricity and space as a bonus.
Faster charging of Li-Ion batteries will always have an impact on their lifespan. Every more complex device today has some electronics that take care of optimal charging, Apple is no exception. However, it is not a miracle that can bypass the irreversible degenerative chemical processes in the battery.
As for replacing a computer with an iPad, as I already wrote in the answer below, for light use, certainly yes, for many years. Although I don't know how old your parents are, my experience is rather that older years tend to have quite a problem with touchscreens, but so be it. Anyway, it's easy to use. However, if we are talking about a full-fledged replacement for a computer, then any common activity on a computer that one does not even think about is often tedious on a tablet, we can start by simply copying text. On a computer, a matter of seconds, on a tablet multiples of this time. And so it is with many things, in short, the touchscreen is a big delay and the mobile OS is an efficiency killer. That's why I'm amazed by the crowd of "professionals" (that is, not exactly the case of your parents) who suddenly threw away the computer and use the iPad. And it's strange that they didn't claim this years ago, because nothing has changed with the iPad Pro that would make one completely replace a computer if they haven't already. In the name of Apple's marketing, these professionals probably voluntarily extended their working day to double, or in short, they are simply talking :-)
Apple describes charging their Li-ion batteries well here: http://www.apple.com/cz/batteries/why-lithium-ion/
After all, Federico also refers to this in his article, which is why he only measures charging from 0 to 80%, because then the speed decreases, precisely in order to maintain a longer battery life.
OK, I'll take that into consideration when I measure it.
So you can easily add a keyboard to the iPad and they won't type much anymore. However, the price of those devices is worse than if I buy them a laptop, so it won't just happen anyway ;-).
I think that the professionals solve only one specific thing, maybe a few things, and they have a specialized application for that. So, in the case of Pro, it's an extension between drawing professionals, nothing more, nothing less. I certainly agree that there will be some neglected % of them. It's just marketing, it has to say something ;-). Earlier they said and they repeat it again that it is also for education and that is also only used in hundredths of % ;-).
But I'm not surprised that the professionals buy it. It is convenient to carry. And they don't mind the device for 25k, because it will earn them the money again ;-).
Years ago, I saw how they switch the charger between iPad and iPhone, and the measurement showed that when switching, the W decreases just like with the iPhone charger, so somehow Apple must have banned it (unless it was in the last 20%, as it was already written here, that I don't remember if they solved it there at all). But a lot of people write here that their iPhones charge faster, so I'll try to verify that, because I'm really interested.
Otherwise, yes, faster charging = usually higher temperature and that is not good for the batteries. However, the question is how much it will destroy the battery compared to a fully charged one. I would really be interested in that. You know, I have an iPad 1, and it's about 7 years old, and the batteries are in good condition, so at least the batteries haven't worn out that much ;-). If someone told me that the battery will last up to about 80% for 7 years and if I charge faster for 6 years, then I don't think so. It would then be exchanged for a new one if I still had the phone somewhere. If someone says it will last for 3,5 years, then it's a given (probably based on the price for replacing the battery ;-) ).
You described the situation accurately. I would sign it to the letter. If someone now needs an iPad Pro as their main computer, an Air 2 would certainly be enough for them. I also have days when I can get by with my Note 3. But even simple editing and filling in tables in Excel is 10x faster on a normal computer. And it doesn't matter if I'm editing the table on a Note 3 or on my friend's Air 2. It can't compete with a computer. I'm not even talking about writing in Word. Mark a piece of text with the mouse and edit it on the computer in a matter of seconds.
I would still dwell on the Apple trick that I get a charger for the device for almost 30 thousand, which is not capable of charging it in operation. Incredible. Jobs is turning in his grave. In the end, one has to buy a GREAT PRODUCT for 2200, and even the right Apple fans take it as a great option. It's pathetic.
Ondrej, be careful what you write. In my opinion, the sentence "The standard 12W adapter may be good for charging iPhones faster" is wrong. As I looked at the testing where the charging speed is measured, the iPad charger charges the iPhone just as fast! The reason is clear, Apple stopped it (probably the battery wouldn't have tightened it) :-).
My experience is that the iPad charger is always faster :) At least with my iPhone 6 Plus.
Charging is also faster with the 5S, about as fast as charging from USB3 ports on a PC. The classic small iPhone charger is incomparably slower
Challenge accepted :-). I'll try it ;-).
So resolved :-).
1 hour and 7 minutes from 11% to 76% – iPhone charger.
1 hour and 6 minutes from 11% to 76% – iPad (12W) charger.
So I was right, it's exactly the same. The minute difference is given by the inaccuracy of the measurement.
For more, see the last answer.
You will make me try it :-). I saw first hand a meter that automatically measured a different consumption when switching between an iPad and an iPhone ;-).
There is nothing easier than putting the iPhone in a 15W charger for 5 minutes and in a 15W charger for 12 minutes. You will know the difference right away.
Of course it's faster and I'd like to see the mark :)
I don't think so ;-). Today I will still charge the charger from the iPad, so I will also bring my own conclusions :-).

I was right.
By the way, I have a 6s, it must be a 6s Plus otherwise (but I would be surprised).
I measured mainly with the mobile phone turned off (the display was turned off - I was just checking percentages, back calls, playing games, etc.).

Here are the sophisticated measurements:
https://www.youtube.com/watch?v=Y_X821UlWYw
I just did a really quick comparison. I was charging my iPhone 6 Plus.
iPad charger:
14 minutes = 15%
iPhone charger:
14 minutes = 9%
Did you do anything to it during that time, or did it go dormant?
He lay motionless, only two notifications came to him.
Same as me. The biggest downfall is probably the display.
My roommate and I bought an iPhone 5s around the same time, and while I charge everything possible: 2.5 A (15 W) at home, 2.1 A in the car (10,5 W), 2 A at work (10 W), 1 A in the apartment (5 W), so I basically only charge my roommate with the supplied 5 W charger (1 A), and after some two years I have to say that my battery has actually grown much more, I need to get to 20% in the afternoon and he has 40%... on average, my mobile phone is emptier in the evening and I dare to say that we use it in the same way. So I really think that charging faster for the long-term battery is not quite the right thing to do. With an iPhone, it probably doesn't matter and it can be replaced quite cheaply, but with an iPad, which generally has a much longer moral and functional lifespan than a phone, I would probably reach for a faster adapter only in cases where it would be absolutely necessary.
According to what I measured today and yesterday:
1 hour and 7 minutes from 11% to 76% – iPhone charger.
1 hour and 6 minutes from 11% to 76% – iPad (12W) charger.
It doesn't matter which Apple charger you use ;-).
I would almost be worried about non-original accessories and getting the battery into big swings. Ideally charge between 20%-80% ;-). It also depends a lot on what things you have turned on on your mobile phone. Kamos lost 50% of his battery due to a bug in the GMAIL application. He switched to Apple MAIL and suddenly it drops by 20% ;-).
