Redmi note 3 is hands down THE BEST SMART PHONE you can buy under 12k.
It is available in two variants.
16 GB storage with 2 GB RAM and
31GB storage with 3GB RAM.
If you are a heavy user then I will suggest you to go with the 32GB model since it handles heavy task with ease and three is very good ram management in this device and there fore its snappy , fast and very fluid.
The battery life is so craazyy Good here.you can get upto 2 days of battery life easily with this device.
Screen on time is nearly close to 8 hours approximately.
The camera is very good for the pRice you are paying for.don’t expect much from this camera.its just a good camera and gets the job done with your selfies , portraits etc .
One thing to note here is that this device comes with a hybrid sim slot.that means you can’t usE 2 sims and memory card at same time.
You can use either two sims.or one sim and a memory card.
The out put via the head phone jack is also good and there is nothing Much to complain about.
As far as performed goes.this phone is just blazing fast.you can heavy gaMes like asphalt 8, nova 3 etc with no lag what so ever.and that big 5.5 inch display doubles enjoyment.
The speaker output is writ weak.If u keep it on table.The sound gets muffled.
Overall all this device is highly recommended if you have a price budget of rs 12k .
Just go for it and I am sure that you will like that device and will be happy with it.
