Hi I have replaced new battery on Iphone5 . now it shows charging indicator but not charging and stay at 45%. double check with old battery and now causing same problem. close examine logic board two parts are missing near battery connector. could any body help me out parts no and from where I can get it Thanks see picture

I marked missing part with 1 and two thanks

That would be the C277 (1) and FL10 (2) which both are on the BATTERY_NTC line pretty sure from there comes your problem. Best way is to swap them from a donor board if you have.
