The Mi 10 Ultra by Xiaomi is one of few phones that supports 120W fast charging. It is also one of the few phones that support Quick Charge 5 which brings 100W+ fast charging.
Xiaomi ships the Mi 10 Ultra with a 120W GaN charger in the box, unlike some manufacturers that include a slower charger than the device supports or no charger at all. This means that if you purchase the Mi 10 Ultra, you can experience this ultra-fast charging technology right away.
A battery charging test to see how fast the phone charges has revealed that the Mi 10 Ultra charges at a slower rate, actually a much slower rate but one that is still faster than most of the devices on the market.
The battery charging test was carried out by the folks at Android Authority and they discovered that the M1 10 Ultra actually charges at just 80W compared to the 120W advertised by Xiaomi.
The test revealed that the charger begins drawing 92.3W of power when first plugged in but then falls to 86.4W for the most part of the charging duration. The power received at the handset itself is 80.1W which, of course, is really fast, taking just 21 minutes to fully charge from empty. The phone was also charged with an 18W adapter and that took 68 minutes to fully charge.
For those concerned about battery temperature, the peak temperature at 80W is 43.8°C which is higher than the ideal temperature of 40°C. This peak temperature will be much higher if the phone actually charged closer to 120W. The phone was also charged at 50W which took 29 minutes from empty to full and at a peak temperature of 39.1°C. That sure is a small difference in charging time seeing as there is a 30W difference between the power ratings.
It is important to state that the Mi 10 Ultra doesn’t maintain a high temperature all through the charging duration when charging at 80W. The temperature falls when the battery level gets to 70%.
At 80W, the Mi 10 Ultra does charge pretty fast, much faster than most phones. However, we are sure folks will be pretty disappointed at the fact that it doesn’t actually charge at 120W, which, to be honest, is probably better for the phone’s battery health.
