Ampere is working great on my Nexus five. I've done a lot of messing around with power chargers and cables. The maximum output in amps is almost always listed on the wall charger. The current carrying capabilities of the USB cable seems to be directly proportional to the gauge of the wire inside. most of the micro USB cables you will find for a few dollars at the drugstore are 28/28 AWG and that will let less than 1 amp through. With nexus 5 screen on and running Ampere I was showing around +50ma. I would have to turn my screen off for me to actually notice an increase in battery. I believe the USB cables that are shipped with your phone are generally 24/28 AWG. I'm not sure what the maximum current of these cables are because I'm sure my Nexus five tops out before the cable does. It seems as though my Nexus five can handle around 1.5 Amps. With the screen on and Ampere running it shows +700 to +1000 mA. The only difference is the cable. Here is a cable that had been working well for me...

Ron Richards, my boss would like your Google voice number.

They want you to explain why I've spent the last few hours trying all of my adapters, cords and devices in difference configurations. :)

I'm now seriously thinking of doing it all over again, dropping the results into a spreadsheet and calculating the % loss for different cords and labeling them.  I've actually tossed a few that were just crap.

Dam you man, dam you.

If you don't win this week I'll be shocked, one of the best apps to hit the arena in recent times.

I  have been finding solutions to technological hardware and software 'situations' for decades as an electronics tech, electrical engineer and industrial electrician. Imnsho, the Ampere app in nice and clever but not really very effective when troubleshooting. There is a piece of hardware, (that I now consider an INDISPENSABLE TEST INSTRUMENT), about $10US, available from Amazon, that will reliably display true USB amps and volts in vivid red and blue LEDs. It even has two throughputs. I discovered this device a few months ago and it has become more useful than you might be able to imagine. With it: I KNOW ELECTRICAL REALITY. Simple multiplication yields watts (P=IxE). This BESTOPE Digital LED USB Amperemeter Voltmeter has been invaluable in troubleshooting cable, connector, device and power supply problems. I have had one operating perpetually and even with no outputs connected it displays the available output voltage and looks good while doing it. Jump over to the following link and give it a purchase consideration:

Ron Richards? I had to laugh when you said "you can never quantify if a charger is faster than another".

 

Look on the side of the charger, there will be a part that says "5VDC - 1.5A" or say "5VDC - 2A". All USB chargers produce 5V, so just compare the output current. A 2A charger will always charge faster than a 1.5A charger.

Ned Jeffery If you have a poor quality cable this can affect the rate however. If you have a 2A charger, but your phone has all its apps open, it may charge at 1A. If you use a 1.5A charger with no apps open, it may charge at 1.1A. The output stated on the charger is just what it outputs, not always what it receives.

Stephen Syputa  What do you mean by "not really very effective". Have you compared the results obtained with Ampere with those measured using dedicated hardware like the BESTOPE? If so we would love to hear more, I think. On the other hand most people don't care about the accuracy of the milliamp reading that much and just need a way to decide which cable will charge their device faster.
