Wondering when it doesn’t need to be charged I still leave it on the iphone charger at night or even overnight. will it cause any issue to my apple iphone if i leave it to charge for such a long time? i am not sure does the iphone has a auto feature to disable the iphone charger to stop charging the iphone itself. i assume most devices would have such chips or software to do so correct? some information it for me that would be great. since i am not too tech savvy but the iphone has really changed my life since i got it..
