YU Yureka Plus is almost same as Yureka, there are differences in screen and the camera only.
However, if you ask my experience, it’s great! I am not facing major issues in it, the max temperature I face in my phone is like 55C which I think is little more than usual but still, usually it’s so cool.
Also, talking about battery- it won’t be best for you if you loves great battery life. I get around 5-6hours of screen-on-time and usually, one or two days of battery backup.( never tried to keep it on stand-by for long period) .It have good quality screen and camera is great, yet in low light you won’t be able to capture great photos.
The best part of its camera is that it can capture 120-fps video recording, slow motion! And we’re soon going to get 120-fps full HD high speed as well as slow motion video recording with Cyanogen OS 12.1 update, as confirmed by YU Forum!
