How Long Should Laptop Battery Last?

Factors That Affect Laptop Battery Life:

Before we dive into how long a laptop battery should last, it’s essential to understand the factors that affect its lifespan. The following are some of the critical factors that impact battery life:

1. Battery Type:

The type of battery used in a laptop acts as one of the factors which impacts its lifespan. Most modern laptops come with lithium-ion and lithium-polymer batteries. Both of these batteries are pretty good and allow your laptop battery to last longer. The average lifespan of a laptop battery ranges from 3 to 5 years. However, older laptops that still operate on Nickel-Cadmium may have a shorter life. 

2. Usage:

Charging habits and usage patterns play a significant role in determining how long a battery lasts. Running multiple applications and processes simultaneously can put a strain on the battery, reducing its lifespan. Working with resource-intensive applications or keeping the screen brightness high all the time also impacts the overall battery life, shortening its time span.

3. Charging and Discharging:

The more frequently you charge your laptop battery, the faster it will degrade, leading to a shorter lifespan. However, it is essential to note that undercharging or overcharging the battery isn’t a favorable practice either. Thus, it is best to strike a balance and charge your laptop battery when it reaches around 20% to 30% capacity.

Also, given the fact that an average battery allows up to 1k charges, your battery will start to drain a lot more quicker, unable to maintain the juice after it reaches its limit. Meanwhile, if your laptop operates on batteries made of materials other than lithium, then it may approach its demise way earlier than lithium ion or lithium polymer batteries.

4. Environment:

The environment in which the laptop is used can also impact battery life. For example, high temperatures, extreme cold, and the humidity levels can affect the battery negatively, as heat, cold and moisture can damage the battery’s internal components. Also, remember that using a laptop under direct sunlight or near a heat source can cause the battery to overheat, leading to battery degradation. 

How Long Should a Laptop Battery Last?

As mentioned previously, the lifespan of a laptop battery depends on various factors such as usage, charging habits, type of battery, environment, etc.

Generally, a laptop battery should last between three to five years, depending on how you use it and maintain it. Therefore, nothing is set in stone.

Either your laptop battery can work perfectly fine for 5 to 6 years before its capacity to hold a charge starts to drop or it won’t even pass the 2.5 year span, given it’s supposed to complete 1k charging cycles maximum.

It takes going up from 0% to 100% for a battery to complete one full cycle. So, the longer it will take for your laptop battery to reach 1,000 charging cycles, the more years you can use it without a worry.

Usually, folks who do not deplete the battery completely or charge it fully can expand its lifespan by keeping the capacity between 30 percent to 90 percent, delaying the completion of a whole cycle.

How to Extend Laptop Battery Life?

If you want to increase the longevity of your laptop battery, here are some tips that you can follow:

• Adjust Screen Brightness: As your notebook invests quite some power into maintaining the screen brightness; therefore, lowering it can significantly increase the battery life.
• Close Unnecessary Applications: Closing resource-intensive applications, background programs, Bluetooth and WiFi can also help extend battery life. Deleting unused apps also boosts battery performance.
• Disconnect Unnecessary Peripherals: Disconnecting peripherals such as external hard drives or USB devices can help reduce battery drain.
• Use Power Saving Mode: Enabling the power-saving mode on your laptop can also help improve battery health and its overall lifespan.
• Avoid Extreme Temperatures: Avoid using your laptop in extreme temperatures as it can damage the battery. And keep it away from direct heat.
• Charge Properly: Follow the manufacturer’s instructions for charging the laptop battery. Overcharging or undercharging can reduce its lifespan. Also, make sure you charge it till 85-90% and do not let it drop below 30%. Maintaining such balance can be highly useful in elongating the battery’s lifespan.

• Put the laptop to sleep: Put the laptop to sleep when taking short breaks. It often happens that we start using our phones, neglecting the notebook. That’s why either manually put the laptop to sleep or set a timing in the settings.
• Store Properly: If you’re not using your laptop for an extended period, store it in a cool and dry place with a 50% charge.

FAQs

Is it okay to leave my laptop plugged in after the battery gets full?

It’s not okay to leave your laptop plugged in all the time, given that the overcharging harms the battery and cuts down its capacity to hold charges considerably. However, the good news for laptops with lithium batteries is that they do not get overcharged even if you leave them plugged in. These batteries are sophisticated enough to stop charging after the voltage reaches 100% and so, your laptop can rely on the AC power after it
