Ok, I'm not sure if this is am AMP issue or not. The travel charger w/ USB cord that comes with the Skyrocket is part# ETA0U80JBE. It has a 1.0 AMP charging capacity. Most other chargers only have a 0.7 AMP capacity. It seems odd that both the AT&T store and Samsung's own website lists the extra / replacement charger for this phone as one that only handles 0.7 AMPs? Most other places also list 0.7 AMP units as being compatible units. However, if you search by exact part #, there are a few places online including Amazon.com and Ebay that sell the ETA0U80JBE 1 AMP units. They are made by Samsung (they have the Samsung name on them) and they look and have the same specs as the one that comes with the SkyRocket. It seems many (if not most) people that are having the 100% battery issue are using chargers that only deliver up to 0.7 AMPs but the people that use the chargers that came with the phone (1.0 AMP) do not have the problem. The 0.7 AMP chargers work, but I can't help but wonder if they are what is causing the issue. I thought it might be a problem related to the overcharge protection and it still might be. Or it could be a combination of the lower AMPs and the overcharge technology. However, if the overcharge detection ciruit is located in the phone itself, it shouldn't make a diference. If the overcharge circuit is in the charger itself, it might be part of the problem with the lower AMP chargers or chargers that do not have overcharge protection. I am ordiering one of the ETA0U80JBE 1 AMP chargers from Amazon.com just to have a spare. It will be interesting to find out if anyone can identify (without a doubt) what exactly is causing this issue and how to fix it. The lastest OS uprade for the phone did not seem to address it.
