Also if you leave ur battery charged, how bad does that fu*k it up?
I did that on accident cause i fell asleep and now it seems like i'm burning through battery
Once it hits 100%, the phone shouldn't receive a "charge" anymore so no.
I've heard that phones had "chips" now to shut off any further charging (and thus damage to battery) once it's fully charged. Lies. The technology hasn't been implemented yet for a charger not to such power from the outlet if it's plugged in, and for any phone to "reject" the flow of power once fully charged. It will harm and deteriorate ur battery if u charge long beyond 100%.
Moral of the story is get ur S3 fully charged before bedtime (not hard, this ohone charges so fast and depletes so slowly)
