I bought redmi 3s prime before some months for my mom.Intially I was using this phone.I bought this phone through flipkart by seeing the specs.Especially the battery in this phone is 4100Mah Li-Ion Polymer Battery.But after using this mobile I was totally pissed off.The battery is really bad.It gets drained very faster.I had to put it charge for more than 2 times per day.Not only this, there are many other issues in this mobile.This mobile has fingerprint scanner which doesnt works most of the time.Brightness is very much flickering in either mode that is auto-brightness enabled or in manual mode.Voice quality is really bad in this mobile.Also like many other phones this has heating issues.I would suggest to buy some other mobile instead of this.
