Question

Is it bad to charge my cell phone while its turned on?
I almost always get phone calls in the middle of the night for like just random and emergencies and such but i always need to charge it at night. So i charge it while its on but i just got a new phone and i hear thats bad for it and dont wanna ruin it.

Answer

I dont think so, I always do the same and my cell phone still in good condition. However, this may shorten the battery life, so just buy another new battery then ... no big deal. After all its affected your cell phone battery but not your cell phone.
