I'm having a battery draining in idle issue with my phone within one month after buying it, I went to Fade service center four (4) times four times I said them to change battery as after lots of changing software's the problem didn't solved, so I said them to change battery and I went today also. I said them to change the battery but they are saying they will not change the battery. Worst Xiaomi services, I would be afford for other phones worst Xiaomi. The China phones services are awesome, what the hell ***** 😣😣😣
