Hello
This is oppo A57 phone is also good dor to buying option for middle range budget.
Its a nice phone even after 5 to 6 months of usage. It doesnt slow down unlike redmi note 4 which slows down after few months of usage. Oppo A57 is worth spending more money.
its battery backup is good and is better than honor 6x which has higher capacity than oppo a57. Also it just takes 3hrs to charge fully since it doesnt support any fast charging.
So,
FINAL ADVISE = Pick .Go For It if u have budget arround 15000 INR
