It's happened to me, as well, I have tested/measured many types of adapters with different smartphones. I observed that the current flow and adapter are not well-optimized for most smartphones. Thus to adopt it, either you have less Amperage-cable or correct voltage rate level (5V/6V/9V/11V/20V) from the Adapter.
Unfortunately, CN phones with High-Wattage Power or PD & auto-discharge features, like Huawei/Xiaomi/OP, must have their brand charger in order to achieve full support of super/fast charge whatever they called it. Each brand has its own technology & instruction definition for charging.
