Cannot upgrade 40W fast charge.
Because the hardware design of Don DMI does not support 40W fast charging, and fast charging requires hardware support to achieve.
Although the software can be changed, the hardware limitations cannot be changed, so the Don DMI cannot be upgraded to 40W fast charge. At present, there are many mobile phone brands on the market that support 40W and above fast charge technology, which is thanks to hardware upgrades and optimization. Therefore, when we consider buying a mobile phone, we should not only consider the performance of the software and hardware, but also pay attention to whether it supports fast charging technology to improve our charging efficiency and use experience.
