This is a laboratory value that was measured with a battery charge of 1 percent to 100 percent charge – the iQOO 10 Pro has a 4700 mAh battery. For the measurement of ten minutes, Vivo also switched off “all mobile phone services with the exception of calls”, according to the Chinese manufacturer.
To protect the battery, Vivo uses heat-conducting gel and a protective circuit, among other things. In addition, an algorithm should protect the battery condition in the long term. Even after 1600 charging cycles, the capacity of the battery should be over 80 percent, writes Vivo.
Fast charging race
The specified charging time of ten minutes with 4700 mAh corresponds roughly to what competitor Xiaomi has been promising for a long time: a smartphone with a typical 4000 mAh battery can be charged from zero to one hundred percent in just eight minutes with Xiaomi’s Hypercharge system. It should only take three minutes for the cell phone to be half full.
Xiaomi presented and demonstrated this system more than a year ago – but only with a specially built mobile phone prototype. There is still no Xiaomi cell phone on the market that can actually be charged with 200 watts. Vivo achieves the milestone as the first company. This is of little use to users in Europe: Previous models of the iQOO series were never sold outside of Asia.
It is mainly the Chinese manufacturers who are promoting fast charging technology for smartphones and using it for advertising. Manufacturers like Vivo, Oppo and Xiaomi are in a kind of race with each other. In practice, the advances in fast charging usually only play a real role after years, because smartphones usually have to be specially built for this and often take a long time to actually be launched on the market.
In addition, the quick charging technology of the manufacturers is mostly proprietary, so it only works with their own devices with special chargers. On the other hand, the charging standard USB-PD (Power Delivery), which is supported by all current smartphones and also supports various power supplies, is not proprietary. USB-PD can charge a smartphone with up to 100 watts.
