What is the 20/80 battery rule?

The 20-80 battery rule suggests keeping lithium-ion batteries in devices like phones and EVs between 20% and 80% charge to minimize stress, prevent deep discharge and overcharging, thereby extending the battery's overall lifespan and health. While charging to 100% and letting it dip to 0% occasionally is generally fine with modern tech, consistently staying within the 20-80% "sweet spot" reduces physical strain, especially avoiding extreme states for prolonged periods.

A 1000mAh battery's life in hours depends on the device's power draw: divide 1000 by the device's milliamp (mA) usage; e.g., 100mA draws 10 hours (1000/100), 10mA draws 100 hours (1000/10), but higher current drains faster and less efficiently, so it's an estimate.

What happens if I use a 90W charger instead of 65W?

Yes, you can generally use a 90W charger for a device that uses a 65W charger, as the device will only draw the power it needs, but the voltage (V) (e.g., 19V) and connector type must match, and the higher wattage adapter will often charge faster or handle heavy use better without overheating the adapter itself. Think of it like a bigger water pipe: your laptop only takes the water (power) it needs, but the bigger pipe won't get stressed as easily.
