Hi. I bought a Samsung Galaxy Ace last Saturday. When charging a new phone for the first time, I know that you have to drain the battery before charging it 'til the battery's full. I did not know that you have to turn the phone off during the initial charge and you have to charge it for 8 hours. So when I first charged my Galaxy Ace, I did not switch it off and instead downloaded apps from the Market. Now, my phone's battery easily drains. Like if I use Facebook for just an hour or two, the battery icon shows a great depletion. Was this possibly caused by not initially charging the phone properly? What could I do to fix my battery? How many hours should I charge my phone? What is the average life span of your Galaxy Ace's battery? Please help me.
