As laptops get older, their battery capacity tends to decrease. This is because the lithium-ion batteries inside laptops degrade over time. The degradation is caused by several factors, including heat, cold, humidity, and age.
Most laptop batteries will last for around 1,000 charge cycles before the capacity decreases. After that, you can expect the battery to hold less and less charge each time you use it. A few things can cause your laptop battery’s capacity to decrease prematurely.
One is simply age – as your battery gets older, it won’t be able to hold as much of a charge. Another possibility is temperature – if you use your laptop in very cold or sweltering conditions, that can also shorten the life of your battery. If you want to keep your laptop battery in good condition for as long as possible, avoid exposing it to extreme temperatures and try not to let it discharge entirely too often.
With proper care, you should be able to get several years of use out of it before needing to replace it.
What Should I Do If My Laptop Battery Does Lose Capacity?
If you find that your laptop battery is losing capacity, you can do a few things to try and improve the situation.
- First, ensure that you use the correct power settings for your needs. Second, try calibrating your battery.
- Second, try calibrating your battery. This can be done by discharging it entirely and then recharging it fully.
- Finally, you may need to replace your battery if all else fails.
What Are the Main Reasons for a Decrease in Laptop Battery Capacity?
As laptops increasingly become our primary computing devices, keeping them running smoothly is more important than ever. Unfortunately, one of laptop users’ most common issues is a battery capacity decrease over time. Most laptops on the market today have an average battery capacity between 40 and 60 watt-hours.
While there are several reasons this can happen, here are the most common:
Overcharging
This is perhaps the most common reason for a decreased battery capacity over time. You’re damaging the battery when you plug your laptop in and leave it charging overnight or for extended periods.
This is because lithium-ion batteries don’t like to be charged to 100% for long periods of time; they should stay around 80%. So if you’re regularly leaving your laptop plugged in for hours, you’re slowly decreasing its overall battery life.
Heat Damage
Another common cause of decreased battery life is heat damage. This can happen from external sources (like leaving your laptop in a hot car) and internal sources (like using demanding programs that generate a lot of heat). Either way, too much heat is bad for lithium-ion batteries and will decrease capacity over time.
How Can I Tell If My Laptop Battery is Losing Capacity?
Laptop batteries tend to lose capacity over time, and there are a few ways you can tell if yours is starting to degrade:
| Number one | One way is to track how long your battery lasts on a full charge. If you notice that it’s lasting noticeably less time than it used to, it could be a sign that the battery is losing capacity. |
| Number two | Another way to tell if your laptop battery is losing capacity is by paying attention to its performance when in use. |
| Number three | f your laptop seems to be running slower than usual, or the screen dims faster than it used to, those could also be signs that the battery isn’t holding as much of a charge as it once did. |
If you’re concerned that your laptop battery might be losing capacity, there are some things you can do to help prolong its life:
- First, make sure you’re only charging it up to 80% – letting it drain all the way down regularly can also shorten its lifespan.
- Secondly, avoid extreme temperatures – both too hot and too cold – as they can damage the battery.
- And finally, try not to leave your laptop plugged in for extended periods of time when you’re not using it; overcharging can also lead to reduced capacity over time.
How Can I Prevent My Laptop Battery from Losing Capacity?
Laptop batteries will naturally lose some capacity over time due to chemical degradation, even if they’re not used. However, there are several things you can do to help prolong the battery life and prevent it from losing too much capacity too quickly.
Here are a few tips:
| Number one | Avoid extreme temperatures Exposing your laptop battery to extreme cold or heat can accelerate the chemical degradation process and cause it to lose capacity faster. So try to keep your laptop in a moderate environment as much as possible. |
| Number two | Don’t let it discharge completely Allowing your laptop battery to discharge entirely regularly can also shorten its lifespan. It’s best to keep the charge level above 20% when possible. If you know you won’t be using your laptop for an extended period of time, it’s also a good idea to store it with a partial charge (around 50%). |
| Number three | Avoid the “memory effect” by regularly calibrating The “memory effect” is a myth with newer lithium-ion batteries, but if you have an older nickel-based battery, it can become an issue. |
The “memory effect” occurs when you only partially discharge the battery before recharging it again – over time, the battery forgets how to hold a full charge and loses Capacity. To avoid this issue, ensure you fully discharge and recharge your nickel-based battery at least once every 30 charge cycles. For lithium-ion batteries, calibration is still recommended but not as critical – discharging them down to 40% once every few months should suffice.

Sudden Battery Drain Laptop
If your laptop battery drains faster than usual, there could be a few different causes.
Here are some possible explanations for why your battery might be dying quicker than it used to:
| Number one | You’re using your laptop in a hotter environment than usual. If it’s summertime or you’re in a warm room, this can shorten the lifespan of your battery. |
| Number two | Your laptop is getting old, and the battery isn’t as efficient as it used to be. Over time, batteries will lose their capacity to hold a charge as they age. |
| Number three | Too many programs are running simultaneously, and your computer is working overtime. This can cause your battery to drain more quickly because your computer uses more power to run the programs. |
| Number four | One of the apps you regularly use is a power hog draining your battery more quickly than other programs. Identify which app this is and see if any updates could help improve its efficiency. |
| Number five | Your settings may be configured in a way that’s causing your battery to drain more quickly than necessary. For example, if the brightness turns up or has unnecessary background processes running, this can lead to shorter battery life. |
Try adjusting some of your settings and see if that helps improve things.
Laptop Battery Capacity Decreasing
Laptop Battery Capacity Decreasing The capacity of a laptop battery will decrease over time. This is due to the number of charges and discharge cycles that the battery undergoes as it is used.
As the capacity decreases, the time the laptop can be used on a single charge will also decrease. There are a few things that you can do to help prolong the life of your laptop battery and reduce the rate at which its capacity decreases.

- One way to help prolong your battery’s life is to avoid entirely discharging it before recharging. It’s best to keep your battery between 20% and 80% charged when not in use.
- Another way to help is to avoid extreme hot and cold temperatures. Keeping your laptop in a cool, dry place will help extend its battery life.
- Finally, try to use power-saving features whenever possible, such as dimming your screen or reducing processor speed when not needed for maximum performance.
Can We Increase the Battery Capacity of the Laptop?
The answer is yes, but it depends on the type of laptop you have. For example, the battery’s maximum capacity is 95 watt-hours if you have a MacBook Pro. But with some work, you can increase that to 99.5 watt-hours.
Here’s how:
Step One
First, make sure you have a compatible charger. You’ll need one that outputs 20V at 4.5A or 9V at 3A.
Step Two
Next, remove the back panel of your laptop (this will void your warranty). Once you’ve done that, locate the battery connector and disconnect it from the motherboard.
Third Step
Now, replace your old battery with a new one with a higher capacity (we recommend getting one rated at 100 watt hours or more).
Final Step
Be careful when doing this – don’t damage any delicate components inside your laptop! Finally, reconnect the battery connector to the motherboard and reassemble your laptop. That’s it – you’ve now increased your battery capacity!

Why Does Battery Capacity Decrease?
As we all know, batteries are not immortal. They have a lifespan and will eventually need to be replaced. But why does battery capacity decrease over time?
There are a few reasons for this:
1) First, as batteries age, the electrolyte breaks down and becomes less effective at conducting electricity. This reduces the overall capacity of the battery.
2) The batteries’ electrodes also break down with age and use. This further reduces capacity.
3) Finally, self-discharge also increases with age. This is when the battery slowly loses charge even when not in use. All these factors together mean that an older battery can’t hold as much charge as a new one.

You have to know that a new laptop battery should be charged before use. Most laptops come with a charger, but it is always best to check that the charger is working properly before using it to charge the battery.
Conclusion
Laptop batteries typically have a lifespan of two to five years. However, over time the battery’s capacity will decrease, meaning it won’t be able to hold a charge as long as it used to. Several factors can cause this deterioration, including heat, age, and charges.
Heat is one of the biggest enemies of laptop batteries. Overheating can damage the battery cells and shorten their lifespan. So it’s essential to keep your laptop in a relaxed environment and avoid using it on your lap for extended periods of time.
Age also determines how well your laptop battery holds a charge. As the cells age, they become less efficient at storing power. This is why it’s essential to calibrate your battery regularly (about once per month) to help prolong its life.
The number of charges your laptop battery goes through also affects its capacity. When you charge and discharge the battery, some of its capacity is lost permanently. So if you only use your laptop occasionally, you may not notice any decrease in capacity over time.
But the capacity will slowly decline if you use it frequently or leave it plugged in all the time.
