To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The battery life is amazing. I'm an average user, I don't play games but I use my phone the whole day and the battery lasted for 2 days continuously. So yes the battery is amazing and the phone is very light weight. In hand feel is also very good. The camera quality could've been improved but it's a satisfactory phone.
