Battery & Charger
The Mi 9 comes with a 3,300mAh battery. And before you say the word “only”, let me reintroduce a PSA we did years ago. Here’s why your 3,000mAh can last longer. And that article is still valid until today because the Snapdragon 855 has a smaller gate length, hence decreasing power consumption. With further optimization done to the architecture, the power efficiency is improved even further.
Hence, the Mi 9 is actually pretty high up in our battery life benchmark. Take a look at it.
Coming in at just shy of 13 hours, the Mi 9 can last you for a full day’s use quite easily – given that there is no gaming involved. Overall, a very powerful chip yet power efficient.
It’s funny how the Mi 9 is actually compatible with Qualcomm’s QuickCharge 4.0+ but Xiaomi only included a QuickCharge 3.0 charger. But that’s okay – since the QuickCharge 3.0 charger is till way faster than 5V 2A chargers.
For the bundled QuickCharge 3.0 charger, it took about 20 minutes to reach 50% battery and about 33 minutes to reach 75% battery.
As for standard 5V 2A charger, it took about 39 minutes to reach 50% battery and about 68 minutes to reach 75% battery.
