The data cable plays a vital role in the charging process. It is not only responsible for transmitting power, but also for data transmission. Once the data cable is damaged, such as scratches, bends or breaks, it will directly affect the efficiency of power transmission, which will lead to slower charging speed. Therefore, we need to check the status of the data cable frequently to ensure that it is tightly connected and undamaged.

Data cable shady: poor material = turtle speed + short life
Wire core: copper > aluminum > iron
High-quality wires use tinned copper/oxygen-free copper, which conducts electricity quickly; cheap wires use aluminum or iron, which charge slowly and break easily.
Wire diameter: thick > thin
The thicker the wire (the smaller the AWG value), the greater the current, and the thin wire is easy to break.
Interface: gold plating > nickel plating
Gold-plated interface does not oxidize, nickel plating turns black after long-term use, poor contact and slow speed.
Hidden bug that slows down charging
✅ Length trap: 2-meter wire is 30% slower than 1-meter wire, and 1-1.5 meters is best for daily use.
✅ Temperature assassin: Charging slows down below 0℃, and the system limits the current when the phone gets hot.
✅ Protocol incompatibility: Fast charging head + slow charging cable = useless! The head + cable protocol must match.
3 tips to choose the right lifeline
Look at the logo: choose the PD/QC fast charging protocol and the cable with a small AWG value.
Pinch hardness: moderate elasticity + braided layer protection, don't buy if it's too soft or too hard.
Recognize the brand: Apple chooses MFi certification, Android chooses official authorization, safe and compatible.
Tips for speeding up charging
✔️ Change the cable but not the head: If you have a fast charging head, match the protocol cable.
✔️ Shorten the length: 1 meter cable is more efficient.
✔️ Temperature-controlled charging: The room temperature is around 20℃.
✔️ Flight mode: Play while charging? Turn on flight mode to double the speed!
