Portable devices, such as laptops and smartphones, use rechargeable batteries as their primary power source. Charging and maintaining these batteries properly is important to ensure optimal performance and longevity. Here are some tips on when to recharge, whether you can leave your laptop with AC connected all the time, and what charging process can wreck batteries:
- When should you recharge?
It is generally recommended to recharge your laptop or smartphone battery when it reaches 20-30% charge remaining. This is because Lithium-ion batteries, which are commonly used in these devices, have a limited number of charge cycles before they begin to degrade. A charge cycle refers to the process of charging a battery from 0% to 100%. By recharging the battery before it completely drains, you can extend the overall life of the battery.
- Can you leave your laptop with AC connected all the time?
While it is safe to leave your laptop connected to AC power, it is generally recommended to unplug the charger once the battery is fully charged. This is because constantly charging a battery to 100% can put unnecessary stress on the battery and cause it to degrade faster. Additionally, leaving a laptop connected to AC power for extended periods of time can cause the battery to overheat, which can also damage the battery.
- What charging process can wreck batteries?
There are a few charging processes that can damage or shorten the lifespan of a battery. These include:
- Overcharging: Charging a battery past its maximum capacity can cause it to overheat, which can damage the battery and reduce its lifespan.
- Fast charging: Some devices offer fast charging capabilities, which can charge the battery at a higher rate than normal. While this can be convenient, it can also put additional stress on the battery and cause it to degrade faster.
- Extreme temperatures: Charging a battery in extremely hot or cold temperatures can cause it to degrade faster. It is best to charge batteries at room temperature.
- Partial charging: Charging a battery only partially, or not allowing it to fully charge, can cause it to lose capacity over time. It is best to charge batteries to their maximum capacity whenever possible.
So, to maintain your portable device's battery life, it's best to recharge it before it fully drains, unplug the charger once the battery is fully charged, and avoid overcharging, fast charging, extreme temperatures, and partial charging.
