Plug a phone into a modern charger and the first 10 minutes are impressive. The next 20 are not.
This is not a defect. It’s the connected device protecting itself. As temperature rises during charging, a smartphone’s battery management system reduces the current it will accept, because heat accelerates the chemical degradation that permanently reduces battery capacity. The charger may be capable of delivering more, but the device simply stops taking it.
For anyone building products in the portable power category, this creates an uncomfortable gap between specification and experience. A device rated at 25 watts is accurate in the sense that it can deliver 25 watts. Whether it delivers 25 watts for the duration of a charge is a different question, and one the specification does not answer.
The specification gap
The gap matters commercially because it is invisible at the point

Scientists found that a tiny atomic structure that forms on nickel oxide during methane conversion is more effective than the metallic nickel long believed to drive the reaction. The discovery allowed a low-nickel catalyst to rival one containing 10 times more metal, potentially opening the door to cheaper and more efficient industrial catalysts.
