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 phone worked fairly well for 2 years after which it started having problems. It recently became extremely laggy and it would sometimes hang when the camera app was open. I fixed this using a memory-cleaning app. After this, it now just shuts down randomly and gets stuck in a boot loop (won't restart on its own). The only way to let it start up is to connect the adapter and charge. A google search showed that several other models of Redmi Note have reported this issue. These phones don't seem to have a long lifespan beyond 1 year or even 18 months. My first and last Redmi/Xiaomi phone.
