12 hours would be good.
About 4 hours.
you have to charge it first time for 12-16 hours so if you get it early then charge it and do everythign you have to do then go back to it and it shall be done charging. also when your on the internet on the phone, don't let it get too hot because it will overheat and the battery will die hope i could help
After making sure the battery was completely dead (on a Samsung Intensity). It took almost 8 hours to finish charging
3-4 hours if fully dead if not try the math
The Samsung charge includes features such as a touch screen. Also, another feature is that it has excellent battery power. I have read that while in usage its battery power is 660 minutes, while on standby the battery can last up to 280 hours
1) Make sure that the brightness of ur screen isn't too bright as this sometimes can drain the battery 2) The Ace only takes around 3 hours to charge so don't charge this phone over night as thiss can damage the phone. 3) Try charging it when it has no battery left.

You should charge it for at least 12 hours before using it, but after that, it takes about 3-6 hours so you can charge it over night.
