GadNest guides are educational simplifications of how consumer electronics generally work.

• GadNest is not a repair manual. No guide instructs how to open, disassemble, or repair a device or a battery.
• Implementation details vary by manufacturer and model; a guide's general explanation may not match every specific product exactly.
• Any safety-related guidance mentioned in a guide (for example, around charging habits) summarizes publicly available official guidance from the sources we cite and is not a substitute for a manufacturer's own instructions.
• GadNest makes no medical claims. Wearable-sensor guides describe consumer-grade estimates, not clinical measurements.
