Mobile is good. But battery performance is too worst.
It will take 8 hours tofully charge. But discharge within 8 hours if you use internet and 12 hours if its standby. More in words service centers are very worst and they only for paid service and not for warranty customers.
I gave my k4 note mobile for service in Chennai annasalai branch. They not even give response. I called to them but they not even pick my call. Totally worst mobile company I ever seen. Don’t buy any lenovo mobiles.
