Sorry, @
Smittiegee19 and @
theesotericone both have valid points here. I looked at the screenie quickly on my phone and didn't notice there were only 2 minutes of "on" time.
If this issue is when using your Skyrocket, you might try installing the app in this thread:
http://xdaforums.com/showthread.php?p=29451951. You want version 0.3. It will pop up a notification telling you what type of charger was detected and the charging rate. If it detects a charging wakelock (such as with the Apple chargers), it will tell you in the notification it creates.
It's a good troubleshooting tool that I have used many times to sort out bad USB cords, chargers, etc.
I purchased two Griffin dual-USB car chargers that gave me nothing but wake locks (type 6). Griffin is or at least has been seriously in bed with Apple, since these were "Apple certified" LOL.
After determining the wake locks with the Skyrocket Charger Info app, I was able to crack open the cases and solder pins 2 and 3 together on each to convert them to type 2 chargers... There are some good articles out there if you are technically inclined enough to do this and your charger is worth it.
