Why doesnt the battery - HTC Rezound

why doesn't the battery charge while it is plugged in while I'm watching a movie or talking to somebody online it's ridiculous amber light never turned green only when it sitting idle

Most likely because what you're doing, especially the movies is drawing more power than what's actually being pumped into the battery. Get battery monitor widget by "3c" in the market. Very very detailed info about your battery. Ish you never even thought about/existed. Haha. Its very helpful.

How is it being charged? USB or AC... The answer is important, as USB only charges half as fast as AC.
Regardless, the reason is that if you are using the phone heavily, you are using a lot of power. If you are using a lot of power, you may be using all or almost all of the power coming from the charger just to operate the phone.
I have seen power use rates when using the phone heavily that are around 700mA, that is more than the 500mA that you get when charging via USB, and almost as much as the 1000mA that AC provides.
Heck, I have seen power use rates that are up to 1100mA a few times. That is higher than even the AC input.

Here is a screen shot of my charging over the last 12 days. I have NEVER gotten 1k+ (results may vary. As to why, stated in the following) you can see on the bottom screen the max mA peeked at 972. USB doesn't charge at "half" the mA as wall chargers. I thought that too, but did some tests (while VERY bored at work. Haha) and have seen 600 to around 800 mA. It varies on a number of things.
Ie: the USB cord itself. As some are designed for data only or faster transfer rates rather that charging taking priority. (charging light may be on, but thats just because it knows somethings plugged in. Or you could just have a Bonk one. They're are MANY different USB cables today.
The phones kernel, because you'll notice when the phone is damn near dead, USB or wall, will charge at a higher mA and fluctuate at different battery percentages.
A good/stock kernel will charge super fast when battery is very low to get you somewhat charged quickly. Then in the upper percentages it should slow way down especially in the high 90%'s to effectively complete/finish out the charge rather than just throwing rediculous power into the battery across the whole process. Also what other stuff you may have turned on, on the phone like "enable always on mobile data" may be detrimental. Hope this helps man.

It was only a few times I noticed the power use that high.
USB can vary, but general rule is 500mA can be counted on as that is the max that the standard provides.
All charge rates will vary. The main problem is the fact that we usually charge a device that is powered on. The varied power use will cause fluctuations in charge rate.
I need to research more into how Li-Ion charges when the device is still in use. I do know how they charge when not in use, and all the little details of it. The biggest problem is that powered on really messes with how a Li-Ion battery can charge.
I need to get out my stand alone computerized Li-Ion battery charger and do some testing. I have been wondering exactly how much these batteries hold if actually charged properly. Too bad that the Stock OEM batteries are 3.8v nominal, they charge to a higher overall voltage and my charger is not set up to handle the new voltage so I couldn't charge the stock to a real 100%.

if u charge by AC with a 1000 mA you should be fine

Are you watching the movie on your phone or do you have it connected to a TV? The screen being on will draw a lot of power I believe.

Always always wall charged; only used USB to adb stuff never let it charge via usb

If you're charging by USB, forget it.
