Hi,
Xiaomi Redmi Y1 is the worst phone I ever know.
The speakers are of low quality. When ever I play a high bass music it starts to make unclear tearing sounds. You wouldn't enjoy playing a high bass music on this phone.
I charge my Redmi Y1 for 4 hours to get a 100% full charge and it would go down to 0% in less then a hour of use. It features to have 3080mAH battery life, well I don't believe it after using it.
Its not at all meant for multitasking. When ever I down games and play on it the device stops responding. I could get a battery phone then Xiaomi Redmond Y1 in this price range.
