Is Laptop Battery Maintenance Software Useful? Charging And Using At The Same Time Will Not Damage The Battery

When many friends use laptops, the biggest problem is charging.

Should I charge it after using it up, or should I keep it plugged in?

There are all kinds of theories on the Internet, which makes people confused.

Today, we will start a discussion about notebook battery-related matters, and explain charging and maintenance matters thoroughly at once, so that you can feel at ease during use.

Should I use it until it runs out of battery and then charge it?

In the past, old-fashioned notebooks used nickel-cadmium batteries or nickel-metal hydride batteries. These types of batteries have a "memory effect."

If you only give up part of the power every time before charging, the battery will gradually "forget" its overall capacity, resulting in an increasingly reduced amount of usable power.

So older batteries do need to be fully discharged and recharged regularly to stay active.

But now most laptops on the market have replaced Lithium battery .

Lithium batteries have no memory effect, so there is no need to deliberately run them out and recharge them.

On the contrary, often leaving the battery in a low-power state (such as less than 20%), or frequently completely using up the battery (deep discharge) will accelerate the loss of chemical substances inside the battery, resulting in a shortened battery life.

To put it simply: lithium batteries are afraid of "starving to death" and are not afraid of being recharged at any time.

Will using it while charging damage the battery?

Many people worry that leaving them plugged in will "overcharge" and damage the battery.

In fact, this worry is a bit redundant for modern notebooks.

Today's notebooks are equipped with mature Power management chip .

When the intensity of sunlight reaches its peak intensity, the thermometer immediately stops measuring the indoor temperature, and the room uses air conditioning equipment to adjust the temperature.

At this moment, the battery is neither charging nor discharging. It is in a state called "resting", and there is no situation where power is always being forced into it.

What really needs attention is the heat dissipation issue.

When charging and using, the power adapter and the charging circuit inside the computer will generate heat.

If you place your laptop on a quilt or next to a pillow or use it in a poorly ventilated place, the heat cannot be dissipated and it will remain in a high temperature state for a long time. This is the most powerful enemy of lithium batteries.

High temperatures will cause the battery to bulge and permanently reduce its capacity.

So as long as you ensure good heat dissipation, it’s no problem to use it while charging.

How to save battery when not using computer for a long time

If you don't use your laptop for a period of time, if you only carry a tablet with you on a business trip, or if you use multiple computers alternately, then the way the battery is stored is extremely important.

Many people are accustomed to charging the computer to 100% and then shutting it down and putting it away. When they take it out after a few months, they find that the battery is no longer durable.

The correct approach is: adjust the battery power to About 60% Store again.

You can observe the newly purchased notebook. After taking it apart, the battery capacity is usually between 50% and 60%. This is the best long-term storage capacity obtained by the manufacturer through testing.

At this power level, the chemical activity of lithium batteries is the most stable and the self-discharge rate is the slowest.

Please note that the storage environment needs to be cool and dry, away from places exposed to the sun in summer in the car, and away from high-temperature spots around radiators.

Take it out for charging and discharging every three months or so, which causes the ions inside the battery to move, which can maintain better health.

Several details that need to be paid attention to in daily use

The first is to be extra vigilant in high temperature environments.

In the summer, don't leave your laptop in the car, because the temperature inside the car under the sun can easily exceed 50 degrees. However, the damage caused to the battery is almost irreversible.

In addition, try not to leave the battery in constant Very low battery state.

There is a situation where the operating system will often pop up a low battery reminder when the power is in the range of 10% to 20%. When the user sees the reminder, they should find a power source and plug it in as soon as possible. Do not hold on until it automatically shuts down.

Speaking of the battery of a new computer, it has already been activated before leaving the factory, and there is no such situation as "the first charge takes 12 hours".

After purchasing it, you can just use it in normal condition and charge it immediately while using it. There is no need to discharge it or charge it for a long time.

If you care more about battery life, you can set the charging threshold in the power management software of the notebook itself, such as limiting it to only charging to 80%. This is particularly helpful when it is kept plugged in for a long time.

Laptop batteries generally have a lifespan of 3 to 5 years, and it is normal for capacity to fade after use.

Maintain good usage habits, avoid high temperatures, avoid excessive discharge, and provide reasonable storage, which can increase the service life of the battery.

I hope these contents can help you solve the troubles of charging your laptop.
