Odd phone battery issue Answered

So I just threw together 3 AA batteries and wired it to a female USB connector. I then plugged my phone in for charging. To my amazement, the battery meter tells me that the charger is DRAINING the battery. It's at 60%, but when I plug the charger in, it drops down to 20 within minutes. It then stays at 20, untill I restart the phone, where it goes up to 60%. The charging light turns on, and the status in the battery page is "Charging", but the battery is going down. I plug it back in, it goes down. It has 4.5 volts now, but before I did that, I had 4 aa batteries with a 5v regulator running, and it did the same thing. Don't blame that though, because it does the SAME thing when plugged into my laptop. This happened before, but I didn't know it. One of my friends had an Energizer portable charger that did the same thing, and I got pissed since i thought he drained my battery. This is a HTC mogul with an OEM battery and OEM cable. I don't know what's going on here, but I think I might just call sprint up and see what they say.

. You may have to set one of the phone pins high for the phone to know it's hooked up to a charger. Just a guess. See if you can find any technical info on your phone. Googling the model number with " +pinout" appended, eg, "M38S +pinout", works well for me in a lot of cases.

Or a simple polarity problem, I've seen that be the cause, your's is the more likely, sometimes it's as simple as a direct bridge between the two data cables...

Yeah, but it's doing this on my computer too. And my computer has a real, open data connection. It can't be the phone not knowing it's being charged. Plus, the charging light, and the "charging" text on the battery page.

Very odd indeed, not really sure whats up with it, the polarity thing is the only thing I can think of but something would probably warn you of that...
