witch chip should I change, if my iPhone 5s died, while charging?
Hi,
Before answearing my title question I would like to inform you that 1month ago my phone was water damaged (half of it was submerged into water -from top of a screen). When I opened, I saw corrosion on lcd and digitizer socket. I fixed it quite easily. From then it worked fine. Sometimes on rare ocassions my iphone crashed, restarted itself- it looked to me as usual procedure, because it used to crash before water damage. BUT that's not all.. Recently I got a gift: a mobile charging station - a big capacity rechargeable battery with 3rd party lightning cable. I tried couple of times to charge my phone using this gift. But whenever i was trying to charge, an iphone display sometimes ( 1 out of 3 times) showed me a message, that it wont support or accept this cable. And a night before my phone DIED, i used my original cable combined with my sister's LG charger. I remember that my battery was halfway charged. But when I woke phone was dead. NOTHING revived it. I tried rebooting, dfu mode, itunes, charging again, changed battery to new one. So eventually I ended up by investigating logic board. So far ( thanks to your website) I tend to think that it might that one of the chip is broken/bad. BUT WITCH ONE? I WOULD LIKE TO KNOW FUNCTIONS OF CHIPS, WITCH ARE RESPONSIBLE FOR POWER SUPPLY. AND WHAT MIGHT BE THE SYMPTOMS IF THIS CHIP IS NOT WORKING?

I am looking forward to hear from you as soon as possible
Sincerely,
Laimis
