The other is by signaling which is done via D+/- lines 2015-06-22 17:33 the latter is the more commonly used method 2015-06-22 17:34 actually there are two or three different variants of it 2015-06-22 17:34 ~#neo900 bd 2015-06-22 17:34 i guess #neo900 bd is http://neo900.org/stuff/block-diagrams/neo900/neo900.html the very fine and detailled Block Diagram, or http://talk.maemo.org/showthread.php?p=1445200#post1445200 2015-06-22 17:34 this usb-in-the-middle thing might affect the D+/- lines though 2015-06-22 17:34 check the charger chip datasheet 2015-06-22 17:34 o.O that would be bad 2015-06-22 17:35 (datasheet) it has a nice sum up of how the signaling works 2015-06-22 17:37 ha, it's up to tests then :) 2015-06-22 17:37 the voltage drop method basically works like do increase-current until delta-voltage>0.4V; decrease current by one step 2015-06-22 17:39 this method is _not_ safe. some chagers have no voltage drop and still they overheat 2015-06-22 17:40 rare but possible 2015-06-22 17:41 some notebooks are like this, they don't have voltage drop on USB port but simply break on overcurrent 2015-06-22 17:41 it doesn't seem to use this method, the current and voltage are pretty stable 2015-06-22 17:42 yeah, it's not a commonly used method, as I said above 2015-06-22 17:42 it heats up, but doesn't burn hand 2015-06-22 17:42 most common method is D+/- resistor network. Closely followed by D+/- short 2015-06-22 17:42 i guess when it burns hands, it's too late :P 2015-06-22 17:44 it's quite possible that your 1A charger has a voltage drop to 4V or even 3.5V on >1A current, and that automatically reduces the current the phone _can_ draw 2015-06-22 17:44 can you test the voltage? 2015-06-22 17:45 the usb device shows 5.1- 5.2 V 2015-06-22 17:45 it *should* be 5V +/- a few 2015-06-22 17:45 that's great then 2015-06-22 17:46 so voltage drop is basically a protection from overcurrent? 2015-06-22 17:46 rather a natural physical consequence of overcurrent 2015-06-22 17:46 ah yeah, makes sense 2015-06-22 17:47 not always though. See blowfuse 2015-06-22 17:48 it blows when you connect too many heaters to your mains outlets, without voltage drop from 230V to 150V or whatever 2015-06-22 17:48 blowfuses drop the voltage, too ... :) 2015-06-22 17:48 laptops work in a similar way 2015-06-22 17:48 some at least 2015-06-22 17:53 http://portablesolarpanels.co/product/abovetek-usb-power-meter-voltage-tester-current-monitor-usb-2-0-3-0-volt-amp-reader-multimeter-led-screen-portable-durable-mv-ma-measurement-solar-panel-voltmeter-battery-power-bank-ampmeter/ is a great gadget 2015-06-22 17:53 i'm now getting all the phones i have at home and measuring their charge current :) 2015-06-22 17:58 older nokia phone, charged it in the morning, now it wouldn't even start charging, "battery full".
