Seems a little silly to me.
1 amp = 1 amp. 1 volt = 1 volt The source is irrelevant.
Everything you ever wanted to know about USB . Universal Serial Bus - Wikipedia, the free encyclopedia
I guess if it works for you keep doing it.

Mine is kinda strange, about every 3rd or 4th time I connect to the charger it seems to get a full charge and hangs on Full Charge longer before it descends much slower than other times. Sometimes as soon as I remove from charge (USB or wall) its down to 97% in a min or so, I can plug in instantly, and then remove again and it may discharge the same way. Plug it in, wait till green light, and then unplug and it may last an hour or more depending on use, till it begins descending.
Ok, this is a very old thread, and unfortunately, not one that ever got updated to the right info.
Here's the square deal - once the phone is at 100% charge, it runs off of the battery until it gets down to about 92 or 93% then starts charging again. While that's going on, the light is green, as if fully charged, and when you take it off the charger, it says 100% - but it's not.
By the time it updates the status, you've used it enough to wake up all of the services and use an app or something, so it appears to drop quickly to 90 to 92% right away.
That's luck of the draw for when you take it off the charger - if you take it off the instant it hits 100%, you won't notice that drop.
There's no such thing as trickle-charging here - none whatsoever. Trickle-charging this type of battery would cause it to catch fire. The charging circuit does not take it to 100% and trickle charge to maintain parity (aka equilibrium) - it shuts off and on and off and on while the battery goes 100% ->92% -> 100% -> 92%...
Neither is the apparent longer life due to the lower-power charging.
It's due to the fact that the phone eventually figures out it's not doing much overnight, putting processes to sleep and slowing that power dissipation to about 92%.
And what you're seeing is luck of the draw because some morning, you're going to wake up and it's going to seem to be at 90% and if you didn't read this, you'd be confused again.
So - that just means that for thing to work top-notch, you want that charging circuit to be calibrated with the battery (people try to condition batteries but that's not it - this is) - here's how:
Now - you want good advice on good battery practices, and I recommend this - http://androidforums.com/evo-4g-tips-tricks/150799-battery-tweaks-htc-evo-4g.html
USB puts out 5V, the wall charger is no different. It puts out 1 A (1000 mA). USB ports put out 500 mA (std) or less - keyboard and front-USB ports on many PCs put out less - that's all ok, but the lower, the longer to charge. I use a 500 mA USB PC port all the time - only because it's convenient to my lifestyle. I use the wall charger when I can.
Hope this helps, gang!

- with your phone on, charge while observing.
- when it hits green, immediately remove from charger and power off.
- plug back into charger. if not immediately green - your charging circuit is not calibrated. in such a case, charge until green, immediately remove from charger when green and power on.
- plug back into charger. if not immediately green - repeat this process until regardless if off or on, if indicating full charge in one state, it immediately registers full charge in the other state.

So would you recommend doing this as soon as someone gets their new EVO?

It still works!!
I especially registered on this forum to put this post.
I tried USB charging yesterday after reading this and it worked wonderfully!
I just think the wall charger doesn't charge the battery to its full capacity.
its been almost 24 hours since i last charged it via USB and it still has 60% of the juice!!
The use was normal: couple of hours of music, video streaming for an hour, voice calls for 15 minutes.

I think I might get that...it would help with my tangle of wires!
