OEM iPhone 13 battery from Nehru Place — is it worth it at ₹1100?

Got my iPhone 13 second-hand ~1.5 years ago. Battery health dropped from 80% to 65% and the phone stopped charging completely. Original Apple battery costs ₹8k–9k which is out of budget. A Nehru Place shop quoted me ₹1100 for an OEM battery with 1-year warranty.

Has anyone in Delhi gotten an OEM iPhone battery installed from Nehru Place? How was the performance and longevity? Any trusted shops to recommend or avoid?
