Tweaks to Enhance the Battery Life of a Laptop

Though the life expectancy will depend on several external and internal factors, there are a few simple and quick ways in which you can extend the battery life of your laptop.

First, you should adjust the screen brightness. A brighter screen will consume a copious amount of battery power.

If you do not need it, you should switch off wi-fi and Bluetooth because, when on, they will constantly look for nearby devices to set a connection and drain the battery.

You may also enable Airplane Mode to shut down background apps, wireless radios, and other programs and prevent battery drain when you single-task.

In addition to that, you can turn off or unplug peripherals so that the motherboard does not have to power them and drain battery power.

And, mute laptop speakers if you do not need them every time you receive any email, notifications or when Windows boots. Also, empty the disc drive, if any, before switching to battery power.

Also do not keep your device plugged in all the time especially if it does not come with smart charging mode.

Plug it in before the battery dies to prevent reducing its charging capacity and straining the battery.

Make sure that you use your laptop where it is not exposed to extreme temperatures because heat will cause it to work harder and damage the battery.

Finally, as your laptop grows old, make sure that the battery is calibrated.

Things to Look for Before Buying Best Laptops with Long Battery Life

The first, and probably the most important, thing that you should know while shopping for a laptop with long battery life is that, no matter whatever you do, the battery will lose its capacity and wear down over time. That is just the way the batteries work.

However, you can surely choose a good laptop with good specs. This will ensure that it dies slowly. Here are the specs to look for and the rule of thumb to follow.

The screen

Choose a laptop with a screen with lower resolution and brightness. Higher the resolution and brighter the screen is, the more power it will consume.

However, this should be determined according to your work needs. If your job involves basic computing, you should go with a lower HD resolution.

On the other hand, if it needs better graphics, go for a full HD display.

Go for a pricier and more battery hungry screen of 4K resolution and 500-nit brightness only in case of absolute necessity.

CPU

You should also choose the processor of the laptop very carefully if you want a long-lasting battery.

High-end processors, especially those with higher clock speed, will consume more battery power during operation.

You should ideally go with the Intel Core processors that belong to the Y series.

This will consume much less battery power in comparison to that belonging to the U series or H series, in that order.

Also, go for those CPUs that belong to the latest generation because these are specially designed and optimized to use less battery power as compared to the older ones.

A few more dollars now will provide more value in return in the long run.

Graphics card

When you choose a laptop with integrated graphics, the one which comes with the processor, you can expect the battery to last much, much more in comparison to a dedicated graphics card.

Therefore, if your job does not involve any graphics intensive tasks, go with a laptop with an integrated video card.

Form factor

The traditional laptops will have a much longer battery life than those that come with convertible or hybrid design.

Those laptops with displays that can turn 360 degrees or are detachable do not have the room to hold a large battery due to the small form factor.

There may be a few specific brands that come with two separate batteries in a small enclosure, one in the keyboard base and one in the tablet.

However, the battery life advertised for these models are in fact for the two batteries together rather than anyone taken separately.

Other things to consider

The other factors that will affect the battery life includes the backlit keyboard. Though small, it will surely have an impact on draining the life of your battery.

As for the memory, you should avoid the standard DDR or DDR4 SDRAM, if you do not really need it, and go for the LPDDR variant.

Here LP stands for ‘Low Power’ and therefore laptops with an LPDDR memory will have a much longer battery life.

Since the life of the battery will depend on the way you use your system, make sure you use it properly.

Binge watching, running the processor at its maximum speed, and more screen brightness will drain the battery fast.

Even the most expensive laptop will fail to stop faster battery drain under these conditions.

Therefore, make sure that you keep the settings of your laptop right.

FAQs:

Does CPU type affect the battery life of a laptop?

Yes. A high-power CPU will have a higher maximum clock rate which will draw more battery power and reduce its life. It will also generate more heat to damage the battery.

Will the battery life of my laptop drain fast if I play games?

Yes, but how fast will depend on the type of games you play, the specs of the machine, and size of the battery. You will get to play most of the modern and demanding games for a couple of hours on most of the laptops today.

Will the life expectancy of the battery be affected if I use my laptop plugged in all the time?

Not really, but it is good not to. Most new laptops come with lithium-polymer or lithium-ion batteries. These do not take more charge than required. However, repeated recharge and discharge will reduce its lifespan.

How do manufacturers test the battery life of a laptop?

They do so through general benchmark testing for continuous web surfing using wi-fi at lower settings and brightness. Since all these are done under controlled conditions, you should not take their claim on face value.

Should I believe what the manufacturers say and advertise for their laptop’s battery life?

No. Though these are not entirely wrong, these are actually pure estimates. They focus on the weasel words ‘Up To’ to set the highest benchmark number, which is not based on actual PC use.

How can I check the actual battery life of a laptop?

Five steps. Open command prompt by Run as Administrator, type ‘powercfg,’ go to the file location address and open it with the browser, scroll down to find the ‘Battery Information’ section, and calculate the percentage of Design Capacity and Last Full Charge value.
