Xiaomi India — redmi note 3 battery problem and performance

Address:

175101

I bought redmi note 3 in october, 2016. My phone worked well completing one year but after that my phone started facing various battery issues. My phone showed wrong battery readings and when my phone was fully charged, even then my battery would get dead in an hour. Whereas my friend bought a new phone with me but his phone is working perfectly and his phone's battery works all day. But my redmi note 3 cannot work more than 2 hours even after charging it to 90% or 100%. Another major problem is that my phone switches off at 25% or sometimes 30%. I am facing major battery problem and xiaomi has disappointed me a lot. Please help me with this issue
