Xioami Redmi Note 4 should you upgrade from Redmi Note 3 lets see.
Xioami Redmi Note 4 comes with Qualcomm Snapdragon 625 which is downgrade from Note 3 which is power by 650 chip but 625 chip is power efficent and did not heat up but the performance will not be the same as Note 3 it will downgrade but it is ok for day to day usage you will not face any problem.
It comes with three option of 2/16GB , 3/32 GB and 4/64GB and for normal usage 3/32GB is ok for me if you are heavy user than you should go 4GB option that will done the job.
Camera vice is has 13MP Rear and 5MP front Camer which is downgrade from Note 3 because Note 3 has 16MP Rear and 5MP front Camera but the Note 4 has better camera still not the best in segment. And it low lighting condition it disapointed me because Camera are good in other phone like Moto G5 and Honor 6X. If you need camera phone that do not look for Note 4.
Battery wise it has 4000mAh battery backup that is better that Note 3 because it is power by 625 chip that is power efficent and I am getting one and half day of battery backup with normal usage and 8 hrs of screen on time that is good.
Overall if you need Camera phone than it is not good buy but if you need overall good phone than it is good option. Other option are Honor 6X and Moto G5 Plus.
