Best Laptops With The Longest Battery Life Buying Guide

When it comes to finding the best laptop with a long-lasting battery, there are a number of factors that you need to take into consideration to ensure you get the best device for your individual needs. 

Below, I’ll take a look at some of these important areas to focus on when scouring the market for the ideal product. Giving a little extra thought to these will help steer you towards the perfect option, saving you both time and effort in the long run. 


Firstly, it’s important to consider exactly what you’re going to be using your laptop for. This will often dictate how many hours of use you’ll get out of it and how effectively you’ll be able to maximize the battery life.

For example, if you’re listening to music or watching movies all day, you’ll get significantly more unplugged time than someone who’s on business calls all day or editing images nonstop in Photoshop. 

Therefore, it’s important to take into account the nature of your specific needs when evaluating the different battery strengths of laptops on the market.

If you’re planning to perform lots of CPU-intensive or graphics-heavy work, it’s probably worth shaving a couple of hours off the advertised battery endurance. 

Ultimately, the best laptop for long-lasting battery life varies from person to person.

One laptop may be perfectly suited for an avid gamer, while a completely different laptop could be equally suitable for an aspiring artist. It all depends on the specific purpose of the device. 


The majority of people need a laptop that can be transported effortlessly without stress. Therefore, it ideally needs to be lightweight, as well as having a good enough battery life to survive long journeys.

The latter is an important factor to take into consideration when scouring the market for your perfect laptop. 

If for example, you rarely travel long distances and don’t have a lengthy commute to work or college each day, battery life may not be quite as essential.

If, on the other hand, you have daily commutes to and from work and often travel long-distance, a battery with plenty of juice is crucial.  

Specifications and Features

A laptop’s specifications will often determine how effective the battery is. For instance, recent improvements in technology have made CPUs and other vital components in laptops more power-efficient than ever. 

Many of the laptops I’ve mentioned in the list above are powered by Intel’s new Core processors which are highly-efficient at preserving power.

Importantly, this doesn’t affect the overall performance and speed of the devices. Other features such as adaptive brightness, video playback options, and battery-saver modes all contribute to conserving battery life. 

If you’re still really worried about your laptop’s battery life, you can always disable some of the features that put the highest demand on your system such as the graphical effects. 


The design of a laptop is often considered a good indicator of it’s battery capabilities.

For example, the majority of top-ranked laptops when it comes to long-lasting battery life are either traditional laptops or convertible designs with 360° display hinges. 

Detachable Windows tablets aren’t held in quite as high esteem due to the fact there’s simply no room for a sufficiently-sized battery in such a small enclosure. 

It’s worth noting that there are a couple of exceptions to the rule, most notably Microsoft’s Surface Book models which cleverly include two batteries - one in the tablet and one in base of the keyboard.

However, as a general rule, traditional and convertible-designed laptops are the best for battery life. 

Frequently Asked Questions

Is it bad to leave your laptop plugged in all the time? 

The majority of laptops use lithium-ion batteries which can’t be overcharged. This is because once your battery is charged to full capacity, it will simply stop charging - so it’s fine to leave it plugged in. 

If you’re running an intensive program it’s sometimes best to leave your laptop plugged in to reduce the number of discharge cycles on your battery. However, this isn’t recommended all the time, only on occasions where the battery is likely to drain quickly. 

For instance, it’s better to leave your battery at 40-50% capacity than it is to store it at 100% if you don’t intend on using it for a period of time. Degradation typically happens faster on fully charged, unattended batteries - especially at high temperatures. 

How long does the average laptop battery last? 

Most laptop batteries have a lifespan of between 2-4 years, providing around 1,000 charges. This lifespan is determined by a few different factors. 

Firstly, the material of the laptop battery. As mentioned above, the majority of laptops are equipped with lithium-ion batteries. A battery made from any other material is likely to have a significantly shorter lifespan. 

Needless to say, the amount you use the device will also determine how long the battery lasts for before giving in. Laptops that are used daily to run intensive programs and graphics-heavy software will last for a shorter period of time than laptops that are mainly used for watching movies and listening to music.   

While the battery lifespan varies from laptop to laptop, there will always be a point where your device’s battery completely stops holding a charge.

At this point, your laptop will need to be permanently plugged in to use effectively - functionally rendering it a desktop PC. 

How much does it cost to replace a laptop battery? 

The price of batteries depends on the type of laptop you own. Original batteries usually cost around double of a generic type, with laptop manufacturers viewing spare parts as a clear way of making extra money. 

The cost of these original batteries are hefty, so only consider replacing a laptop battery if it’s essential.
