I usually charge when my battery is less than 5%. I charge for 3 hours sometimes 3 hours and 10mins. There were two occasions though that i fell asleep and charged for 4 hours, the other time about 4.5 hours. Will that have a bad effect on my batt? And also is it best to drain the battery once in a while, like once a week. I do that bec i was told it was good.
