|Work Performance Score
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.
