Some chargers can cause “ghost touches” and erratic scrolling because of poor power quality. Electrical noise (ripple), weak isolation/filtering, unstable grounding, and voltage swings from low-quality cables can interfere with the touchscreen controller, especially as the phone warms up while charging. This article explains the real causes and gives quick tests to identify whether the charger, cable, or wall outlet is the culprit.

A 65W charger is not automatically faster for phones because wattage is only a maximum capability. Real speed depends on whether the charger supports the phone’s preferred fast-charging protocol (USB-C PD or PD PPS), the cable’s current rating, the battery’s charging stage, and thermal throttling when the phone or charger gets hot. This article explains why some lower-watt chargers can feel faster in real use and how to choose a charger that stays stable and cool.

A 20W charger can feel slower than 18W because wattage is only a maximum. Real fast-charging speed depends on protocol negotiation between the phone and charger, cable resistance, battery charge stage, and thermal throttling when the phone gets hot. This article explains the handshake logic and a quick test to identify the real bottleneck.

This article addresses common concerns regarding the impact of power banks on smartphone battery health, debunking the myth that all power banks are detrimental. It emphasizes that high-quality, certified power banks are safe, incorporating advanced safety features like overcharge, over-current, short-circuit protection, and temperature control. The true culprits behind battery degradation are identified as low-quality, uncertified chargers, as well as user habits and environmental factors. Key
