The Xiaomi MI9 SE has an ideal screen size and is comfortable on the hands, it has a great quality of image because its screen is amoled. Unlocking through the biometric reader under the screen despite being a new feature, it still has lower quality than traditional, as it is slower and needs some pressure with the finger on the screen to unlock. Another negative point is that it does not have an input jack for P2 (Audio Jack) headphones and has no Micro SD memory card slot. Its battery also does not have a good autonomy, in intense use does not reach 6 hours.
The Xiaomi Redmi Note 4 is a very good smartphone but left to be desired in the front camera being 5MP taking photos with poor quality, its battery although large of 4100mAh does not have a good autonomy and even discharges in less than a day with a use moderate. The operating system is the forte of the smartphone with MIUI 8.
