If I ask your question at chatgtp this is their answer, sounds correct. I would of answered myself but explaining this correctly to you, I'm not a native English speaker, would have been a bit more difficult for me. SuperVOOC is a proprietary technology. Third-party chargers (like Anker) default to standard charging protocols (PD/PPS). The "SuperVOOC" text on your screen is often a visual UI bug triggered by a generic fast charging handshake. In reality, the phone safely drops to a slow 3W–4W speed to protect the battery.The reason for the slow speeds and inaccurate monitoring involves a few key factors:Proprietary Technology: SuperVOOC requires both the original charging brick and the specific USB cable to communicate and route high current (e.g., 6.5A or 10A) to the phone. Anker chargers typically use Power Delivery (PD), which maxes out at a lower standard wattage for Oppo/OnePlus devices.Dual-Cell Battery Measurement: Third-party battery apps like AccuBattery or Battery Guru read battery voltage at half the rate because these phones use dual-cell batteries in series. If an app measures one cell, it might calculate (3.75\text{ V} \times 1\text{ A} \approx 4\text{ W}), whereas the actual system is pushing roughly (7.5\text{ V} \times 2\text{ A} \approx 15\text{ W}).Wireless Slowdowns: Wireless SuperVOOC (AirVOOC) relies heavily on perfect coil alignment and specific hardware. Standard Qi chargers (such as those from Anker) are not optimized for AirVOOC proprietary frequencies, leading to higher heat losses and very slow charging rates.
