[Resolved]  Samsung India — permanent battery backup issue

Address:

78/20, chithra illam, pachaiyappa nagar 2nd street,, 641606

Am ramprasath, note 8 user. Bought on march 9 2019. I have battery issue from the date of purchase. I went to service center 4 times in this 2 months. Every time my mobile get flashed and software updated. Recieved comments from service centre like your device is ok. But really am getting 5 hours of battery back up (Power saving mode on, night mode on, sync off, all apps put in sleep mode).
This time on 9th of this month i went to service center for same issue they asked to me take backup to update software and handed over my mobile for observation, now mobile is like newer one without any datas. Service centre people told that after played 2 hours of video drained only 20%.
I challenge him if i use with datas it will drain from 100 to 0 in maximum of 5 hours, he told that its possible. Today on 11th i collect my mobile and used inside the service center 50% of drained in 2 hours. Then he told its normal one. Really i won't accept this. I need solution for this. Kindly take action on this problem.

Kindly find attached files for your reference.
