Like probably most people on this forum, I upgraded to an HTC EVO V 4G from the Motorola Triumph. All said and done, I don't regret the change one bit, even despite my charging woes... this phone is great!
But either way, I'm having some pretty slow charging. I'm not sure if it is just the way this phone is or if there's a specific issue with mine.
I did do some testing, too. Basically, I took a USB extension cable and cut it open, then hooked a multimeter up to the 5v wire and tested the amperage under various circumstances.
Basically what I was seeing was a steady 550ish mA from the charger regardless of the state of the phone (using apps, video, etc). I tested it with the stock charger, a Motorola charger (from the Triumph), and a Verizon charger. They all put out roughly the same numbers. I was using the included cable for all of this.
With the Triumph on the other hand, I would get about 650 mA, and then if I push the phone a little (get the CPU going, turn the flashlight on, etc) the mA would go even higher into the 800's. The EVO does not seem to do this at all, it just stays at 550mA which sometimes is pretty inadequate in my opinion.
Using a battery monitoring utility (Battery Monitor Widget) I am seeing the available amperage sometimes dip into the negative if the phone is being used while charging, meaning that it is actually discharging the battery even though it's plugged in. The Triumph just pulled charge like a mother****er, and would never do this!
So I'm a little disappointed with the charging, it's very slow. It takes about 3+ hours to charge from 0% to 100% if the phone is on and idle. I don't recall what the Triumph was capable of but I believe it was much better and probably half that.
Oh yeah, one more thing, I wasn't able to directly test the amperage with my Motorola car charger but I can say pretty confidently that it defies all of this and charges the phone fast as hell! Wtf? Why can't the wall charger do that? hah
Thoughts? Anybody having a different experience?
