Work Performance – PCMark

We tested the Redmi Note 4’s performance using PCMark, which simulates work applications like web browing, playing video, writing text and editing photos.

Work Performance Score (Average)	5311	6405	5357	3884
Web Browsing	6038	8045	5643	3688
Video Playback	3873	3469	4487	3789
Writing	5862	7316	5944	4141
Photo Editing	5803	8246	5469	3933

It is important that the key advantage of the deca-core MediaTek helio X20 is not performance, but power efficiency. As the results show, it is about 17% slower than the octa-core Qualcomm Snapdragon 625 that powers the ASUS ZenFone 3, and roughly equivalent to the octa-core Kirin 650 in the honor 5C.

 

Battery Life – PCMark

We then tested the Redmi Note 4’s battery performance using PCMark. It basically ran the PCMark work tests until its battery capacity dropped to 20%.

The Redmi Note 4 (GearBest | Amazon | Lazada) has a large 4,100 mAh battery, but surprisingly, it only lasted just over 9 hours in this test. This is 2.5 hours less than the ASUS ZenFone 3, which only has a 3,000 mAh battery!

Battery Recharging Performance

The Xiaomi Redmi Note 4 comes with a 10 W fast charger. Take a look at how fast it recharges the large 4,100 mAh battery.

It took the Redmi Note 4 (GearBest | Amazon | Lazada) 133.5 minutes (2 hours 13.5 minutes) to recharge its battery from 8% to 100%. This is a battery life : recharging ratio of about 4.5 : 1 – a decidedly lacklustre performance.

The recharging profile shows that the fastest charging up to the 85% charge level, before it tapered off to a slower recharging speed.
