Battery replacement scheme was available India. But, due to absence of Apple store, users have to go to Apple authorized service vendors where services take days. It took me 5 days to replace the battery in Dec 2018 because battery had to be specially ordered.(I live in major Indian city.) Cheap Android phones from Xiaomi etc are flooding the Indian market. If Apple doesn't ramp up the quality of experience in areas other than Hardware and OS, it's gonna lose whatever market share it has in India.
