Qualcomm Snapdragon rotten means that the recent generations of Snapdragon chip power consumption is relatively high, large heat.
To rot is to say that things have not been able to develop in a good direction, so they simply no longer take measures to control them and let them continue to develop in a bad direction. To say that Qualcomm Snapdragon is rotten is mainly to say that Snapdragon 870\/888 and mobile 8 platform power consumption control is not good, chip temperature is too high. And every upgrade performance improvement is like squeezing toothpaste, because the Android Qualcomm Snapdragon is a monopoly and does not compete with Wall-E.
