I finished reading the entire thread last night. I really loved your post. You have a great sense of humor, which I didn't know about before seeing that post. Calculating the real differential between water hose flow thru capacities at different diameters which are Cross Sectional was just what everyone following that thread needed. You brought it all back into perspective. I really was laughing as I read it.
But to stay within the context of the thread, there was a link posted to a YouTube video

where it was demonstrated by using a Kill a Watt meter that had the Apple 12 watt power source connected to its output side, That the wattage reading on the meter when the 12 watt power source was attached to the IPad 3 the meter showed 12 watts being drawn through it, and then by attaching the same power cable to an iPhone 5 the meter showed a drop in wattage consumption to exactly 5 watts. Just as you tried to explain to me so many times, because I can be such a stubborn "#%*+"

. I did try the same experiment, I have 2 of the same devices used in the video. Kill a watt.
I did get one normal reading on my IPad 2, it was using 10.1 watts so then I plugged the 10 watt source into each of my IPhones. Initially the two #4 phones were consuming 5.8 watts on the same meter with the same 10 watt source. The iPhone 4S I recently purchased was consuming 6.5 watts! They were all on while I tested them. Putting them to sleep reduced the power draw level by about .3-.5 watts. I then wrote this all down. Switched the source to one of my apple 5 watt cubes, woke up all the IPhones and I got the same exact readings using 5 watt power source that I got with the 10 watt source. Proof to you once again. The power sources wattage doesn't affect the IOS devices energy draw.
However a few minutes later on the same power cube of 5 watts the 4's headed down to 5 watts, but the 4.s it never went under 6.5 watts. Until it hit about 85-90% charge where it dropped down to under 5 watts and then less again, which looks a lot like a power regulater system going into the absorption phase after running at full flow for the first 80% of capacity. So draining it to under 80% was relatively easy and once again it registered 6.5 watts. In that video the iPhone 5 registered at a perfect 5 watts power draw.
So I posted this in that thread, but the reply I got back basically negated the measurement techniques of the one used in the video. I matched the method used precisely. I even got the same results from both of my Kill a Watt meters.
And I got the same results on 2 different 5 watt apple power sources and on one 10 watt source. So I am controlling for possible equipment defects.
I realize that I am not measuring how much of that 6.5 watts was actually going into my iPhone 4S, that was what was pointed out to me in the reply I received, but then again, neither was the gentleman in the video measuring the actual iPhone device power going to the device. He was just measuring the power sources watt usage plugged into the meter which was plugged into the 110 volt power strip. the same way I set it up. So I should have seen what the video showed which is 5 watts per phone.
I did see that regardless of the 10 watt or the 5 watt supply the phones were drawing the exact same amount of power 5-6.5 volts as they were on the 10 watt source. My hat is off to you. Again my sincere apologies. I have never done anything like I did before and I never would do that again. I am still horrified that I did. I don't know what came over me.
Since the reply itself basically negated the results obtained in the You Tube video link which a lot of people really agreed with strongly including Lawrence F and myself as well. I would have replied back but that thread had gone on for a very impressive amount of posts, and I calculated that perhaps asking you for some help and advise here, would be more productive.
Over there unless I could post directly to just one or two of the participants, perhaps to Lawrence F I am just asking for a whole other world of pain and arguments. What do you think is happening to my phones? It seems plausible perhaps that the iphone4s its power regulating circuits may possibly not be so great, or am I missing something once again??
Plus The iPhone 4"s initially were also drawing 5.8 watts each. Though the dropped to 5 before that 80-85% level was reached. Not quite like the video's precise and clean results? This was all a major surprise to me. I can't adjust it, nor would I try to without a third meter to verify the two I have. Now instead of finding solutions occasionally for fellow apple IOS device owners, I find that I have power issues that to me are inexplicable, ( but probably arent obscure to you) right after I finally really got the concept of Internally built chargers and internal sophisticated charging circuits!
If I didn't have 2 kill a watts I would think it was a malfunction in the meter itself. But I do have 2 of them, and they both read the IPad power draw exactly to specifications.
So what do you think about that... Ha!! Ironic isn't it?
