Performance 

Mi Mix2S at this moment is one of the fastest phones that were tested on Antutu where it scored a remarkable score of over 266.584. This is a great score and it definitely outsuns the Exynos 8895 based Galaxy S8, Snapdragon 821 and last years Snapdragon 835 based OnePlus 5T.  In the charts below, you can see how the Mi Mix 2S compares with the other phones. 

We saw a similar situation in the Geekbench single thread score. the Snapdragon 845 dominates the competition. In this particular test, the phone is 26 percent fastest from the fastest SoC in last year, the Snapdragon 835. It is even faster from Older Qualcomm SoC's and Exynos 8895. 



Again a great leap with the Xiaomi Mi 2S. this is the fastest Geekbench multi score we ever saw on the Android based phone. The new SoC is really doing a good job. 



Xiaomi Mi 2S is again the fastest SoC. if you compare the score with two years old Google Pixel phone you can see that the new SoC scores almost 40 percent better. This is what the people who are upgrading after two years should expect from the new phone. Xiami Mi 2S is much faster and it has the camera that gets close to the performance of the PIxel 2 device. 

During intensive use, the phone almost never gets hot not even warm, thanks to its ceramic shell which dissipates heat. 

Battery 

The Mi Mix 2S has 3400 mAh battery which might suggest that it’s not that much considering the size of the screen and the powerful internals, but Xiaomi managed to get a very respectable battery life out of this unit. With moderate use, the device can last 1.5 to 2 days on a single charge and in heavy usage scenarios it can last the full day which seems is a rarity these days with phones with big screens and powerful specs. 

In our recent trip to Shanghai we managed to shoot more than 200 still photos and few dozens of video files with usual browsing, checking social sites and syncing several email accounts, and it got us through the day. For comparison, my daily driver, a Google Pixel phone, would die in the middle of the day after all this use.
