I just bought one today (it's so cute) and I noticed that the battery is running down pretty quick on mine also. I've had it on the charger at least twice today so that it wouldn't die. I actually had to make a stop at Wal-Mart to buy a car charger just so it wouldn't die. You're not crazy and it's not just your phone.

I got the gravity recently and had the same problem. I'd charge it fully and then it would die in a few hours with little or no usage. Thinking I had a bad battery, the t-mobile store gave me a new battery. Same problem again, so they gave me a whole new phone and battery. I'm having the same problem with this phone now. I'll be taking this phone back and getting a Nokia. I should have known better than to get a samsung phone.

the gravity has a pretty small battery and that might be the reason why your phone keeps running out of battery.

it definitely isn't just your phone.

its suppose to be able to have standby time of around 300 hours.
