iPhone 5c charging only with iPad adapter

Hello. I have problem with iPhone 5c doesent detect normal iPhone charger or computer. It doesen't show bolt symbol when charging with iPhone adapter. I have tested charging current and it is only 0.11A and it charging so slowly it takes days to full charge. But with iPad adapter the amp current is about 0.80A and it charging with it. Now I have replaced Tristar three times but still not normal current with iPhone adapter, it still gives the same 0.11A and with iPad adabter it still works nice. Can somebody tell what there is going on and what I should chek next. Any help would be really appreciated.

@inspiraattori you did not tell us if you replaced the iPhone charger. If your phone pulls 0.11A from that charger but 0.8A from the iPad charger I'd be looking at the charger not the phone.

Thank you for your answer. Sorry I forgot to tell that I have tested it with many different iPhone chargers (working) and cables, and still the same 0.11A. And today I tested iPad adapter and it charging just fine with it.

...and with iPad adapter the bolt symbol appear as well in that iPhone 5c.

@inspiraattori only thing I try different at this time is a new battery.

@oldturkey03 I just replaced the battery with known good battery and still same situation, no bolt symbol and no charging :/

You should be pulling more than 0.8A, unless the battery is mostly charged. Have you tried replacing the Dock Flex? Also, Tristar (U2) isn't the charging IC.It serves to communicate with attached peripherals. So if you phone is charging and is recognized by iTunes, then Tristar is working properly.

Charging is handled by the PMIC (U7) so I would start probing that area to see if anything is wrong.
