Redmi — Defective product Redmi K50i recently bnought.

Hello,
I purchased the recently launched Redmi K50i on 15th Aug. The defect I experienced through this is Slow charging, Overheating, Wifi (Hotspot ) connectivity breaks, Standby time is less, Loading time within file transfer within phone is quite high as its 8GB Ram and 256 Storage.As its mentioned it comes with 67W Turbo charger but not giving performance.

Detailed Description of defect.
1.Using the phone, I first charge from the charger came through box (i.e. 67 W) on 16th Aug.It took 1hr 5 mins to charge from 15%-100%.I have noted the timings as well.

Same happened on 17th Aug.I charged it from 5%-100% it took 1hr 20 Mins.Its really taking more time as mentioned in companies description.
2.It got discharged by giving a standby power of 17 hrs only, so discharging is quick.

Next day on 17th Aug as well the discharge was quick by giving standby power of 16.5 Hrs only.

3.While Charging the phone also overheats as it's mentioned it has cooling technology but I don't think its working properly as I can feel the heating too much.

4.When I am transferring the data from one folder to another in the Files it was not quick. (As I bought the 8GB/256 version).

5.The WIFI is aso not stable.In my last Mi phone I had this issue was not there and connectivity from phone to Laptop through Hotspot was amazing but in this it sometimes doesn't connect and if connect but couldn't give the right speed and it makes connectivity issues.

It's been like 3 days I am facing this problem.The store from which I bought this is not answering the calls, so I have to approach the service center.

I visited your service center today regarding this problem. They were saying yes there is a problem in the unit.

It's like 3 days since the issues are arising, I think the same will come after 1 or 2 months.

I need a replacement of this phone or a refund of my money.

I have been a MI user for the past 5 years as well as my whole family using MI phones but really disappointed this time.

Please replace this unit or refund my money back.
