The first point: power consumption is a serious injury. Ever since I got it, I have been looking for solutions everywhere. Therefore, the system version was upgraded from 12.0.2 to 12.0.5 and finally to 12.0.7. Finally, the problem has not been completely solved. The main performance of K40' s power consumption is that it can lose 25% of the power within 7 hours at most. For a time, mobile phones were like hand warmers. Whenever you touch it, you will feel warm. If it is cold for several days in a row, it will be a weapon to warm hands, but now it is summer. So, Xiaomi engineers, solve it quickly. We can't ignore Redmi just because it is cheaper than Xiaomi's digital flagship. In the long run, it will be good for the pink people. Let's talk about the temporary solution to power consumption, turn off the sleep mode, restart the mobile phone, and clean up all the data managed by the mobile phone. Moreover, the mobile phone must be turned off and restarted every few days, preferably every day. This kind of power consumption is quite normal. If it is not restarted for a long time, it will enter the fast power-off state again;
The second point: the screen will be green; It seems that many netizens have encountered this problem. Unfortunately, I have encountered it, but this problem does not affect the use. Only in the dark environment, when switching from high light to dark light, it will flash for a while, and other places will not affect it basically, but it is still a defect. Many netizens have retired because of this. I don't know what the best straight screen Mr. Lu said. I can't see it anyway.
The third point: the phenomenon of screen flicker in dark environment; K40' s so-called best straight screen is not as good as Mr. Lu's. Those screens that are not the best have DC dimming, which can eliminate flicker on the screen in dark environment. Why doesn't your best screen support it? I believe I'm not the only one who has this idea!
