Caught: Xiaomi makes false promises with top smartphone

Last updated on March 9, 2021

Xiaomi has done a lot right lately. The Chinese company is conquering Europe and recently even overtook Apple. But now it is known that Xiaomi is promising something with the top smartphone that is not being kept.

Xiaomi Mi 10 Ultra does not charge with 120 watts at all

It was a milestone for the smartphone industry. With the Mi 10 Ultra, Xiaomi has for the first time brought a mobile phone onto the market that can charge extremely quickly with 120 watts. Now it has been tested how fast the mobile phone really charges – and that is significantly slower. Android Authority measured the power of the power supply unit that the Mi 10 Ultra has. Instead of the promised 120 watts, it's just 80 watts. A third less than the Chinese company says.

Two values were measured from the power supply of the Xiaomi Mi 10 Ultra. First the power that the power pack draws from the socket and then the power that actually reaches the cell phone. Instead of the promised 120 watts, the power supply unit only draws 86.4 watts from the socket and then only delivers 80.1 watts to the smartphone. Of course, this is still an incredibly good value, but far from what Xiaomi states for this mobile phone. The 120 watts that Xiaomi promises here are therefore not possible and therefore actually no longer a record that the Chinese company claims to have set with this mobile phone. After this discovery, you will of course keep checking how fast the power supply units actually charge.

Xiaomi is supposed to charge mobile phones wirelessly with 80 watts:

Not only Xiaomi gives too high values

Android Authority has not only tested the Xiaomi power supply. In order to have comparable values, other manufacturers were put to the test:

  • Huawei 40 watts: 28.6 watts from the socket – 23.1 watts on the mobile phone
  • Poco 27 watts: 31.6 watts from the socket – 26 watts on the mobile phone
  • Samsung 25 watts: 23.8 watts from the socket – 20.2 watts on the mobile phone
  • Google 18 watts: 17.1 watts from the socket – 14.3 watts on the mobile phone

What power adapters pull from the socket hardly reaches the cell phone. Poco's power supply even draws more watts from the socket to just about reach the value that is stated. Otherwise, all power supplies consistently deliver too little power and the loss of energy is relatively high. Xiaomi is still the best with 7.3 percent power loss – even if the 120 watts are not reached at all.
