The Xiaomi Mi Mix 3 comes with a 3,200mAh battery, which is not the biggest battery size for a phone with a massive, 6.4-inch AMOLED display.

Naturally, we were curious: can such a relatively small battery provide enough juice and power the phone through those longer days?

To understand that, we turned to our trusted battery life test. This is the same test that we have been running on phones for a few years now, so you can not only get a number, but you can see how battery life on a particular phone compares to its peers and even to phones released way earlier.

The Mi Mix 3 scored right in the middle of the charts, with a battery life just shy of 8 hours.


This battery score is right on par with last year's Mi Mix 2s and is a decent score by any means. The result is on par with the battery life of the Samsung Galaxy S9 series, but we should note that many phones in 2018 have actually stepped their game up and devices like OnePlus 6T, Huawei Mate 20 Pro, iPhone XR and others deliver a much better battery life.

Charging Time


The other aspect of the battery experience is the time it takes to charge up a phone from 0 to 100%. The Mi Mix 3 supports 18-watt fast charging and it comes with the fast charger in the box. Not just that, you also get a fast wireless charger included in the box for free as well! Awesome!


It took the Mi Mix 3 less than an hour and a half to reach a full charge. This is among the fastest charging phones around, practically on par with the charging speeds of champions like the OnePlus 6T.
