Anyway, I'll get hold of a genuine Apple iPad charger and I also look forward to the results of your tests with iOS 7
I just tried a 3GS (6.1.6), a 4S (7.0.6) and a 5S (7.0.6), all under 30% battery. The all took between 0.94 and 1.01 amps from an iPad 12 watt adapter. My iPad with 70% battery draws 1.66 amps from the same adapter. From my earlier measurements all devices start to decrease charging current around 65%.

Mar 10, 2014 7:49 PM in response to Serenity12by gaberdine mac,An Apology
<Deep breath>
I was wrong. I retract my claims and apologise for the fuss I caused.
I was wrong to jump to the conclusions I did; I was wrong to jump in and post those half-baked conclusions in Apple Discussions; I was wrong in the claims that I made and I was wrong in the way that I made them.
No two ways about it, I was completely wrong in my claims and I acted foolishly. I am deeply embarrassed.
Look, there's no excuse for it but, by way of explanation, I can only offer that I was suffering a high fever on Saturday. I must have been completely raving as a result - though at the time I believed I was quite lucid - and it's quite a shock to realise this.
I genuinely don't recognise the person, who two days, ago was convinced that 2+2+z+y = 42 and, now that I'm emerging from it, I am disturbed that my judgement could have been quite so baldy impaired. In truth I should not have been allowed out of bed, let alone writing gibberish on a computer.
It's taken me several days to recover enough strength to come back and face up to my mess but I'm not going to shy away from it. I'll post a simple retraction on every thread where I posted my unjustified claims.
Finally, in case I was rude or offensive towards anybody (I can't bring myself to read every post), I apologies unreservedly to the individuals concerned.

Mar 10, 2014 7:55 PM in response to gaberdine macby gaberdine mac,A Footnote (in case anybody thinks I might have had a point):
More than likely my USB meter is defective - probably over reporting the current. On any sane day I would have simply calibrated it with a test load before considering any conclusions. I'll do that tomorrow FWIW.
As for the supposition that using a new adapter suddenly reduced my battery life, I must repeat what I would normally tell anybody else: that correlation does not equal causation and post hoc does not imply propter hoc. And as for the lower charging current from the Apple adaptor: it turns out that wasn't made by Apple at all but was a low-powered fake that somebody had swapped with mine. Far from that one being my "known, good unit", it was the test subject and the non-Apple one was actually giving the baseline value.
As we know, the device sets the maximum charging current for a USB charger, not the power adapter, and there are no grounds for suspecting that Apple's devices are anything other than perfectly tuned in this regard.
But the minutiae really don't matter. The fact is, I accept that I drew unjustified conclusions from limited and potentially worthless data and then went ahead and published without corroboration or peer review - an academic mortal sin. It's quite out of character - but I quite literally wasn't myself when I did it.

That takes an enormous amount of maturity. I am extremely impressed that, not only do you have the strength of your opinions, you have the courage and integrity to acknowledge your mistakes. If you deal this way with the big issues in life, as well as little ones like this, you're doing very well.
Best of luck.

Mar 11, 2014 6:49 AM in response to Meg St._Clairby gaberdine mac,You are very gracious, Meg. Thank you.
I believe that nobody should take credit for their successes without also embracing responsibility for their failures. If I didn't apply that to myself - irrespective of how things came about - I couldn't hope to expect it of others.

Mar 11, 2014 7:20 AM in response to gaberdine macby Lawrence Finch,A very mature approach. Thank you for your contributions. You inspired me to repeat work I had done months ago, because it is certainly possible that a change in software could have made a difference.

I hope to see you around the forums. I've no doubt you'll have a lot to contribute.

Jun 15, 2016 12:17 PM in response to Meg St._Clairby tally.bookman,I waned to say something similar; most people involved were fairly level-headed (on the Internet!), and your taking the time to undo what damage you perceived to have caused is admirable. I know I, as I imagine most, would be tempted to "make it right" by just never posting on the topic again, but that is not good enough lol. Actually, a pet peeve of mine is how much society seems to value "Being Right" and "consistent". Like it considered a failure if a scientists has a hypothesis that fails under testing. They don't want to submit that paper, but it is at least as valuable as being "right". Never being wrong, taken to the extreme, means one also never learns anything. I think what people are using "being right" as a proxy for is "everything was done competently and in good faith and therefore any result was worth the investment of resources (potentially the time of many valuable people; tax or other $$; time on scarce equipment; etc.)". It seems to me that is the goal; it would still be embarrassing, I imagine, to have to retract something you've claimed precisely because the work was not done competently (whatever awful bug you had that gave you a fever was quite clearly NOT very good at electronics ;-). But you DID retract and apologize for any unprofessional behavior. All in all a healthy exchange; and again, on the _internet_ even; who would have guessed? :-)
