I have been using Redmi 4 for almost a year now. Even though it has lots of features at the price point of Rs 9000, yet I feel redmi could have done better in providing a better phone. Let me guide you through the pros and cons of this phone.
Pros
Look and design - It looks great, very similar to IPhone 6
Budget phone with finger print scanner, IR blaster and VOLTE enabled. ( You dont have to use Jio calling app to call)
The phone is user friendly and has MIUI 9 update.
Cons
Camera - The camera quality is not very good, you will get a yellowish tint when using flash. There is no built in establization so your pictures comes shaky or frames drop in video recording. Daul rare camera could have been better.
Battery - Even though it has ha 4000 mah battery which gives good backup initially, however as you use this phone you will realise that after few months the battery back up has reduced. It generally gives a back up of 5-6 hours if you are using 4G continuously.
Sound quality should have been better.
Screen ratio - It does not have 18: 9 screen aspect ratio like the phones we have for this price at this moment.
Final verdict - It is not value for money at this point of time when we are getting better feature loaded phone for the same price.
