While discussing battery life recently, a sprint salesman told me it is a bad practice to use your phone while it is connected to the car charger.
For some reason, it diminishes the life expectancy of the cell phone battery.
The man sounded very confident about this fact, but did not explain how the damage occurs.

Well, since I had a full battery at 4:05 pm yesterday, I am now down one bar on the battery meter today, at 9:26 am. To go from a week of standby to 2 days max, over one charge cycle, there's something wrong.

Yep. Battery was dead by 6:00 pm.
So now I'm just killing it some more by turning it on as much as I can. I tried hooking the battery itself up to a 12 volt light bulb, but it didn't have enough juice. I'm sure current was going through it, but it wasn't lighting up.
Last time I had it on a voltmeter a couple hours ago, it was at 2.7, the wrapper says it's a 3.7. There's enough power in it to light up my screen for a half second every few minutes.
Spoke to my sister who has the exact same phone as me, she's had her phone longer than me, but she said her charger packed it in and she had to get a new one. If that's my problem, I'm gonna drain this sucker down as low as it'll go and charge it up at work tomorrow. I have a charger there too. One for home, one for work, one for truck.
Anyway, we'll see. I'll keep you all updated.

An update.
I charged my phone at work on Feb 11th, I got 7-1/2 days of standby, after completely killing my battery overnight. I keep a charger at work for the rare time I have a dead battery there. A work buddy also uses it.
I charged it again on the 18th, on my charger at home. I tolerated the low battery warning for about 6 hours, and finally plugged it in when it powered itself off. Still showing full charge today. Looking like I'll be able to go to Wednesday again, maybe even Thursday morning.
Again, no change in my regular usage. Normal calls, calls using the bluetooth headset, texting, everything appears to be back to normal.
But I have yet to plug it in to my car charger. We'll have to wait and see.

Something is wrong for sure. The wife has a samsung from verizon and you can leave it on the charger all night and then less than 12 hours later it alerts to a weak charge. I think to make more profit they use a cheap battery and of course will sell you another one for even more profit.
