Its performance is good and the battery lasts as long as three days of my use. Never hangs or gets lagged.I have brought this phone two weeks earlier. I thought if it does not work I would return it back. But it do. More than my old MIUI prime2. I play the most. So it goes longer. It does not get heated so fast. But the perfect maintanance would bring the phone to work more than 4 years.
