Cotton is known to shrink when exposed to heat, while polyester is more resistant to shrinking. Therefore, a fabric blend of 80% cotton and 20% polyester is likely to shrink, especially if exposed to high heat during washing or drying. To minimize shrinkage, it is recommended to wash the fabric in cold water and air dry or use a low heat setting in the dryer. **

It is generally recommended to charge the battery from 20% to 80% to prolong its lifespan. Charging the battery from 40% to 80% can still be beneficial, but it may not provide as much of a lifespan extension as the 20% to 80% range. Additionally, charging from 20% to 80% can help reduce the stress on the battery and minimize the risk of overcharging. Overall, it is best to follow the manufacturer's recommendations for charging to ensure the longevity of the battery. **
