If you just bought or are planning to buy a new laptop, one of the most important questions you may ask yourself is how long this new machine should last. In other words, just how many years of service can you expect from this new and expensive convertible?
Well, if you wonder how long should a laptop last in terms of its overall lifetime, read on and find out. We also have tried to find out how long an average laptop battery should last on a single charge. Today we’ll also answer the question of how many years of service can you expect out of a typical notebook battery.
Let’s kickstart this guide by determining just how long should your laptop battery last. Modern laptop batteries use Li-ion technology. This translates into a pretty long lifetime of more than five years. If you treat the battery well, of course. As for the single change life, it mostly depends on the work you use the notebook for.
Average single change battery life in modern laptops
Modern laptops can last a very long time on a single charge if not used for demanding work. For instance, let’s look at the latest Asus ZenBook 14. Average battery life on a single charge when using the device for WiFi browsing is set at almost 550 minutes. This translates into nearly ten hours of uptime, which is pretty good.
On the other hand, the average battery life under heavy load is only about 60 minutes. Similarly, if you look at the 2022 Lenovo IdeaPad Gaming 3i you’ll see that gaming laptops aren’t exactly champions of durability.
The best ones offer just more than ten hours of uptime when watching YouTube videos. The average battery life for a gaming laptop is around 300 minutes or six hours of undemanding work. When gaming, you’re looking at an average lifetime of fewer than two hours.
As for MacBooks, the 16-inch Pro model equipped with the M1 Max chipset can last 17 hours during the movie playback test. Further, it lasts 15 hours when browsing the web via WiFi. However, even the latest and greatest MacBook can’t last more than just a hair over one hour when put under maximum strain.
As you can see, a new and relatively modern notebook can last about ten hours when used for light work. As for an average gaming laptop, these devices can last for about six hours when used for light work. When playing games, their average life drops to less than an hour and a half.
So, if you own a new multimedia/general-purpose laptop, you should expect it to last about six to more than ten hours when used for browsing or watching YouTube.
Note that reviews usually perform these tests with the screen brightness set to 50 percent. In other words, expect shorter battery life if you crank the brightness to the max. When doing demanding work that sweats all components at once, you shouldn’t expect battery life noticeably higher than an hour-hour and a half.
When it comes to gaming laptops, curb your expectations. Your average gaming laptop should offer about six hours of battery life when browsing or watching videos. If you try to play a game on your typical gaming laptop, you shouldn’t expect more than an hour to two hours of uptime.
How to improve single charge laptop battery life
You can improve your laptop battery life on a single charge by doing the following:
Drop the screen brightness – Aside from the processor and the GPU (in gaming laptops), the screen is the most egregious battery hog in almost every notebook. By dropping the brightness to 50 percent or less, you should squeeze some extra uptime of your laptop battery.
Avoid using the laptop for resource-heavy work while not plugged in – using your convertible for 4K video editing or gaming without hooking it to a charger is a prime recipe for draining the device out of juice in record time. If you want your battery to last longer on a single charge, avoid doing anything remotely intensive before hooking the machine to a charger.
Use Windows Power Manager – Windows Power Manager tool can noticeably increase your average battery life if you often use your laptop on battery. You can, for instance, underclock your CPU, power limit your GPU, turn off the display after a minute of inactivity, and use other ways to increase the battery life.
Use Your Laptop’s Power Utility App – Besides Windows Power Manager, users can also tweak settings in their laptop’s power utility app to conserve battery. You should have a command center or a power utility app preinstalled on every new device. These apps always offer different power plans, each including different power limits for the CPU and GPU. If you want to increase battery life while away from the charger, pick the silent, low-power, quiet, or any other power mode that looks like it’s the low-power mode.
Disable wireless services – Another way to increase the battery uptime is to disable WiFi & Bluetooth when unplugged. Use them only when needed. This will give you a slight battery life boost.
Fully switch to SSDs – if you have an older laptop replacing its HDD with an SSD will not only drastically improve its performance, it’ll also improve battery life. An SSD also uses much less power than a hard drive, making your laptop last longer on a single charge.
Get a device with Nvidia Optimus or AMD Switchable Graphics – Switchable graphics feature allows a device to switch from a dedicated GPU to an integrated GPU for graphically light work to save power. Many gaming laptops come with Nvidia Optimus and AMD switchable graphics. They use the iGPU for all tasks that don’t need much GPU power. And when you want to game or edit a video, the device will automatically switch to the dedicated GPU.
Get a power bank – Finally, if you want to increase your laptop’s average battery life, get a chunky power bank. While power banks are usually used with phones, larger models work great with notebooks. A massive power bank can immensely increase your laptop’s battery life.
What’s the lifespan of a typical laptop battery?
Batteries in every single battery-powered device, including laptops, degrade over time. As they go through more and more charging cycles, their capacity slowly degrades. After a couple of years, your battery capacity might drop noticeably.
A Li-ion battery can last through 300-500 charge cycles without noticeably dropping in capacity. One charge cycle includes a full charge followed by a complete drain. This means that topping a battery to 100 percent and then using it to 50 percent before charging it again doesn’t represent a full charging cycle. Instead, this accounts for one-half of a charging cycle.
In other words, if you don’t use your laptop on battery often or if you don’t wait for the battery to die fully before recharging it, your battery can last much longer than 2-3 years. Technically, Li-ion batteries can last upwards of 10-15 years. However, if you use the laptop regularly and the battery goes through regular charging cycles, it will show wear-and-tear signs before the five-year mark.
So, if we’re only interested in whether a battery is working or not, a laptop battery can last longer than a decade. On the other hand, if you expect a certain amount of uptime for the battery, the time for replacement will come much sooner. Probably around year 3-5.
When’s the time to replace the battery?
Obviously, you should replace the battery if it can’t keep the charge for longer than an hour or two, even during light work. Next, if your laptop randomly shuts down even when the battery shows a certain charge level, and you know the battery’s the issue, you should replace it.
Next, if you experience a case of a swollen battery, take that thing out and replace it immediately. A bloated or swollen battery is a serious safety issue. It can damage your laptop, even hurt you, if not immediately removed.
Finally, replace the battery if you need like half a day to charge it. If it can last longer than a couple of hours but needs half a day to charge, something isn’t right.
Overall, if your device shows any sign of battery malfunction or severe battery degradation, feel free to replace it.
How to extend the lifespan of your laptop battery
While you cannot prevent your laptop battery from degrading and, ultimately, becoming unusable, you can extend its life by doing the following:
Don’t wait for the battery to die and never fully charge your laptop – Remember, a full charge cycle includes the battery charging to 100 percent and then being fully discharged. Instead of doing this, you can hook the laptop to a charger as soon as the battery level drops to around 30 percent.
Use the smart change feature, if your laptop comes with it – you shouldn’t charge your laptop to 100 percent. Instead, unhook it once the battery level reaches 80-85 percent. Many modern laptops even come with a feature that limits the charge percent to something like 80-90 percent. Try finding that feature (usually called smart charging or something like that) on your laptop.
Don’t use the quick charge feature – If your laptop has a quick charge feature, don’t use it. Only use it when you really need the battery topped out quickly. Quick charge means increasing the charge current. This results in a higher temperature of the battery while charging. And since lithium-based batteries hate higher temperatures, you will decrease the battery’s lifespan if you always use quick charge to top it up.
Higher temperatures will degrade the battery faster – If your battery is always running hot, it will degrade faster. So, make sure to keep your laptop as cool as possible when not using it for intensive work or gaming. Get a cooling pad, undervolt the CPU & GPU, and use battery-saving power options.
If you have an older laptop, don’t leave it plugged in all the time – Many modern laptops support direct power delivery that bypasses the battery if the battery is fully charged and the device is plugged in. Older laptops, however, won’t bypass the battery once it’s charged, which means you’ll reach the max charge cycle limit faster. Also, the battery heats up while being charged, and high temperatures will also degrade the battery more quickly.
How long should a laptop last?
Now that we’ve talked extensively about battery life let’s talk about how long your typical laptop should last. While we didn’t find any in-depth studies trying to answer this question, a recent Office Depot study has shown that Americans upgrade their laptops every 4.8 years on average.
Further, a study by Intel has shown that business laptops older than four years have to be repaired more often. They also cause much longer downtime for workers than two or three-year-old devices, on average. Finally, they’re also more prone to data loss. In other words, your typical laptop will show increased signs of degradation after four years.
Of course, these results aren’t be-all-end-all for all laptops. For instance, if you’re fine with your device being somewhat slow but still able to play YouTube videos or keep dozens of Chrome tabs open, and you only use your laptop for YouTube and browsing, you can keep using that notebook until it drops dead.
That can happen after five years or more than a decade. But as long the device performs snappy enough for your needs, it’s perfectly usable. Next, if you have a work laptop and you use & abuse it for hours on end every day, that device will probably have a shorter lifespan than an average laptop. And that’s completely fine.
Cheap vs. expensive laptops
Pricier notebooks tend to last longer than more affordable models. High-end devices usually feature excellent build quality. Not only that, but since they come with faster hardware that hardware will keep its pace with software for longer.
On the flipside, higher build quality is often followed with not that great repairability. Replacing a keyboard or swapping a battery on a flagship laptop with a magnesium unibody is way harder than on a cheap device made of plastic with easy-to-remove bottom panel.
Windows laptops vs. MacBooks
Regarding the Windows vs. MacBook life expectancy, MacBooks are expected to last longer since they are expensive, high-end machines.
MacBooks almost always have superb build quality and they usually pack latest and greatest hardware, allowing them to stay relevant for quite a while.
Even today, Amazon and eBay are filled with listings selling used & refurbished MacBooks from almost a decade ago.
However, that doesn’t have to be the case. For instance, lots of MacBooks equipped with Butterfly keyboards have experienced keyboard issues. Many devices even had their keyboards dead or broken way before you’d expect a MacBook’s lifecycle to end.
Next, with each new MacBook lineup Apple is making them harder and harder to repair. These days, even a battery replacement on a newer version of MacBook can be a DIY nightmare. This can lead to a shorter average lifespan for newer MacBook models.
Finally, don’t forget Apple and their closed ecosystem. The company tends to offer OS updates for its laptops for longer than five years. However, once your device’s software becomes outdated, it may become incompatible with your iPhone or iPad. You can also miss on cool new features only available on newer Mac OS versions.
So, your typical laptop is usually rated to last three to five years. If you’re using your laptop for light work, you take good care of it, and you’re fine with it performing slower after a while, that device can last for a decade without the need for a replacement.
But even if your laptop works fine, the time will come to replace it one day. But when’s the right time to replace your current laptop?
When should you replace your current laptop
Our advice is that you should replace your current laptop once it can no longer work according to your needs.
For instance, if you have a gaming laptop and your gaming performance expectations include running the latest AAA games with medium details and 40-60 frames per second, once the device fails to output such a level of performance, it’s time to replace it.
On the flip side, if your average usage only includes YouTube, Word, Chrome, and maybe VLC for watching movies and TV shows, as long as your notebook’s capable of offering usable performance you shouldn’t replace it.
Finally, suppose you’re a video editor living off the work you perform on your laptop. If you see a new model offering like 30 percent faster video editing performance, you should get it if the added performance is worth the price in your specific case.
We’re trying to tell you that as long as your laptop offers a serviceable amount of performance and all features you need, keep it. Replace it if it dies or fails to provide a usable experience according to your standards.
How to keep your laptop in good shape
You can extend the life of your device by taking good care of it. Here’re some tips on how to keep your laptop in good shape:
Always carry it in a bag or laptop backpack.
Use laptop skin decals to keep the laptop body in good shape for longer.
Never charge the battery to 100 percent.
Replace the battery once it noticeably degrades instead of replacing the whole laptop.
Check whether adding more RAM or a faster storage drive can improve the laptop’s performance before opting for an upgrade.
Use USB-C instead of the classic barrel charging port if possible since barrel charging ports are known for their fragility.
Make sure to repaste the CPU and GPU every couple of years, if possible.
Avoid using third-party antivirus software on Windows devices. The preinstalled Windows Defender is all you need in 2022.
Keep your OS clean, don’t install random apps, and keep the OS updated to the latest version.
If the device becomes too slow and unusable, make sure to reinstall the OS and check for hardware issues before replacing it with a newer machine.
As you can see, your everyday laptop should last between three and five years. However, if the machine fulfills all your needs and works fast enough, its lifespan can be much longer. A decade or more for a quality laptop used for light work and media consumption is not that unusual to see.
The most important thing to remember is that you shouldn’t replace your laptop as long as it offers fast enough performance relative to your specific needs and requirements.
As for the battery, your typical Li-ion battery will start to degrade after 300-500 charge cycles. While this sounds like the battery can seriously degrade after less than two years – if we assume one charger per day – that number can be much higher if you avoid topping up the battery to 100 percent and plugging it in only after it goes below 20 or 10 percent.
As for the average battery life on a single charge, it depends on the laptop itself and the type of workload. Your average notebook should allow you to browse the web or watch YouTube for at least six hours with 50 percent screen brightness.
That same device will hardly give you more than an hour or hour-and-a-half of charge if you use it for video editing, code compilation, or gaming.
To summarize: a laptop battery should offer at least five to six hours of usage for light work and an hour or two hours for heavy work and gaming.
