Chosen Solution

My phone has always had a problem with battery, it will take over half an hour for it to go on 5% and drains easily! Recently I dropped my IPHONE6S (whilst dead) and its a blank screen? when I plug it on charge the logo doesn’t show, and no response… I’m wondering if its my battery broke…My IC charging or my LCD???

First of all, were you aware that Apple has a “recall” in place for the iPhone 6S for what it calls unexpected shutdowns. That’s a euphemism for bad batteries. Check out this website and see if you phone is eligible for a free replacement. Now your more recent problem, a dead phone, could be caused by the drop damaging the logic board or the battery. I would try to see what Apple can do for free, you may get lucky. Otherwise, you can either try to troubleshoot the phone yourself, which will require a replacement screen and battery or have it done by a reputable shop.
