For creating the Xiaomi Mi Note 3 Performance Review, we received the Android smartphone in a 64 GB ROM / 6 GB RAM version from gearbest.com. The device is officially unlocked and running MiUI globeROM, a custom firmware made by mi-globe.com.

For testing the CPU performance, we are connecting the device via USB/adb in developer mode and execute special commands on operating-system-level! In this test we are compressing 1 GB of data with gzip, which is used quite a lot in real conditions like browsing the web or extracting archives. This test is great for comparison with other Android smartphones or the Apple iPhone.
Using only 1 Core, it took 17.33 Seconds to compress 1GB of data. This is a rate of 59.1 MB/s !
Using all 8 Cores at the same time the device was able to compress the data a lot faster. 8x 125MB (1GB) data has been compressed in only 3.99 Seconds. This is a rate of 256,64 MB/s !
The Qualcomm SDM660 Snapdragon 660 features an Integrated 11ac Wi-Fi via Integrated 11ac Wi-Fi + WCN3990 companion chip with a Mu-MIMO Peak Speed of 867 Mbps !
In our Mi Note 3 performance Review, it was capable of connecting to 2.4 GHz and 5 GHz networks.
|2.4 GHz||Link Speed: 86 Mbit/s
Channel width: 22 Mhz
|5 GHz||Link Speed: 866 Mbit/s
Channel width: 80 Mhz
iPerf is a tool for active measurements of the maximum achievable bandwidth on IP networks and network interfaces.
On a 5GHz wifi connection under real conditions, we could reach a maximum transmissions speed of 214 Mbit/s ! That means that downloading a 1GB file from the internet is done in ~40 Seconds (26.75 MB/s).
Under a cloudy sky, the Xiaomi Mi Note 3 could lock the location in 3 seconds ! In comparison, it had the most stable signal strength while having a great accuracy!
Storage / SD-Card
Smartphones and other systems perform thousands of read and write actions every day. The performance of the Android internal storage is therefore a very important indicator for a smartphones general behaviour and a smooth control of the device.
We did not use any caching mechanisms for this test!
In our Mi Note 3 performance Review, we could reach write-speeds up to 297.0 MB/s. 1GB of data is written in 3.44 Seconds!
Reading the previously created 1GB file has happened in 2.65 Seconds. Thats a rate of 386.2 MB/s!
We did a long-time video test to see how long the battery can keep the device running. For this test, we put the phone in airplane mode and set the display to maximum brightness!
On this conditions, we were able to watch a 1080p h264 Video File for 8 hours and 34 minutes until the phone switched off!
