Such batteries will consist of two cells. Both parts will have to be charged at the same time, at least that should be the meaning of the word “parallel”.
Earlier this year, Xiaomi introduced the Mi 11 Pro smartphone with a 5000mAh battery that supports 67W charging. In the future, the company may offer support for up to 120 watts. This is, of course, not a new technology, but not yet widespread.
Xiaomi could improve this technology and increase the number of smartphones in which it is used. Unfortunately, this is unconfirmed information, so it should be treated with a grain of salt.
