I’ve been using the Xiaomi red mi note 4 for four months and I have to say that its the best phone i’ve ever had . Eithet talk about it’s battery backup or its performance it stand at top. M sure that you won’t get any smartphone with performance at this level on this range .Unfortunately it has got some camera issue as it gets some grain on low light conditions but yup it can be minimised if you use some manual controls.
