2. Best practices for charging laptops
1.Avoid overcharging: Modern laptops are usually equipped with intelligent charging management functions, but it is recommended to unplug the power supply after it is fully charged to avoid being fully charged for a long time.
2.Keep the battery between 20%-80%: Lithium batteries last longest in a medium state of charge, so avoid completely draining the battery or leaving it fully charged for an extended period of time.
3.Use fast charging moderately: Although fast charging is convenient, it will generate more heat and may affect battery life. It is recommended to use the standard charging mode in non-emergency situations.
4.Pay attention to the charging environment temperature: High temperature will accelerate the aging of the battery. Avoid direct sunlight or high temperature environment when charging. The ideal charging temperature is 10℃-35℃.
3. Charging characteristics of laptop computers of different brands
| brand | Charging characteristics | Battery care recommendations |
|---|---|---|
| Apple | Support USB-C fast charging and optimize battery charging function | Turn on the "Optimize Battery Charging" feature |
| Dell | ExpressCharge fast charging technology | Charging threshold can be set in BIOS |
| HP | Supports fast charging, and some models have battery health managers | Avoid long-term storage with full power |
| Lenovo | Rapid Charge technology, Vantage software manages charging | Set charging threshold (e.g. 80%) |
| ASUS | Supports fast charging, and some models have battery health charging options | Optimize charging with MyASUS software |
4. Misunderstandings about charging laptops
1.First use requires full charge and discharge three times: This is a concept from the nickel-metal hydride battery era, and modern lithium batteries do not need to do this.
2.Must be used up before recharging: Deep discharge will damage the lithium battery. It is recommended to charge when the remaining power is about 20%.
3.If not used for a long time, it should be fully charged and stored.: The correct approach is to store the battery at about 50% and charge and discharge it every 3 months.
4.Non-original chargers cannot be used at all: As long as the voltage and power match, reliable third-party chargers can also be used, but they may lack some fast charging protocols.
5. Laptop battery maintenance tips
1. Complete charge and discharge once a month (from 100% to less than 20%, then fully charged) will help calibrate the battery power display.
2. If it is connected to the power supply for a long time, it is recommended to charge the battery to 80% and then unplug the power supply, and then use the battery to provide power to about 50% before plugging in the power.
3. Try to avoid charging in high temperature environments and wait until the device cools down before charging.
4. Use officially recommended chargers and charging cables to ensure charging safety and efficiency.
5. Check the battery health status regularly. Most operating systems provide battery health reporting functions.
Through the above scientific and reasonable charging methods, the service life of the laptop battery can be effectively extended and the best performance can be maintained. Remember, the battery is a consumable item. It is normal for the capacity to decrease after 2-3 years of normal use. There is no need to be overly anxious.
