Just some FYI because I seen someone ask before. I timed it. From 5% battery life left on my storm and tour to fully charge and charging icon goes away was roughly 2 hour 20 minutes.
The charger used also make a huge difference in how long it takes to charge. Most of your car chargers that you would buy from Verizon would be considered rapid chargers and can charge your phone from dead to full in about an hour. Most of your travel chargers(typically the ones that come with the phone) are 2-3 hour chargers.
