Hello, I have a problem with the Xiaomi Redmi Note 4x phone. The battery very quickly discharges, on the wifi when using the Internet or watching Youtube endure 1-1.5 h, and without using a phone and turned off the wifi around 12h. Another problem is switching off the phone with about 20% of the battery. I do not know what can be a problem and if the battery is still working, additionally the phone stops charging when it is not on something
Thank you in advance for your help.
