best browser to save battery life

Browser power consumption is crucial for both mobile devices and PCs. No matter whether your device is older or newer, prolonging battery life is essential, not just by using certain Windows features, but also by using the right apps.

That said, developers have woken up to the idea of developing software applications that are less demanding in terms of battery power.

Needless to say, the same applies to web browsers given that these are some of the most used applications too.

Which browser uses the least battery?

Yes, browser tabs do drain the battery of your device, as they put a strain on both your CPU and RAM. Even though not all browsers require the same amount of resources, having your battery drained after opening too many tabs is a common occurrence.

To fully understand the level of battery that each of the most common browsers uses, our team of experts has tested them rigorously, ensuring the same testing conditions across the board.

To observe how each browser has performed in the battery tests, our team of experts has used an ASUS TUF Gaming F17 laptop with the brightness adjusted to 200 nits.

Each tested browser went through rigorous processes, including web workload variations. Then, the same tests were repeated for each browser until the battery ran out and the laptop turned off.

The tests were measured in minutes of operation performing the benchmarks, meaning the higher value is better.

Here are the results:

BrowserTest score in minutes
Microsoft Edge529
Opera One521
UR Browser496
Brave Browser485
Firefox471
Chrome452

As you can see from the table presented above, at the top of the list, we have Microsoft Edge with a score of 529, followed closely by Opera One, which scored 521.

We were surprised to see how good the new Microsoft Edge browser is regarding battery consumption. Even if there is a difference of only 8 minutes between the two, Opera One balances everything out with the number of features and other features.

UR Browser is not that far away from Opera One either, with a score of 495, and then close behind we have Brave Browser, which scored 485, thus making the difference almost unnoticeable in normal conditions. However, if you’re worried about extreme situations in which 10 minutes will make a difference, then going with Opera One is the safest choice.

Firefox has gotten the 5th place after our test results, and right after we have Chrome, which was able to run the test for 452 minutes, making the difference between this browser and Microsoft Edge a whopping 77 minutes.

Considering all this data, Chrome is the last browser you want to use if you’re trying to save battery.

In today’s guide, we will be discussing some of the most battery-efficient browsers on the market, which, in turn, also shows the browser that uses less CPU and RAM for everyday usage.

Does Firefox use less battery than Chrome?

To answer this question with confidence, our team of testers has taken both of these browsers through rigorous benchmark tests and will present the results to you.

Their tests were performed in the same exact OS conditions, on a separate system, with a fresh installation of the respective browser being used.

Each browser was tested with 10 identical tabs open, and here are the results:

BrowsersCPURAM
Chrome5 – 13 %1783MB
Firefox3.1 – 4%847MB

As you can see, Firefox uses 3.1 to 4% of the CPU, and 847MB of RAM, thus clearly taking the lead when it comes to resource consumption.

Chrome uses 5 to 13% of the CPU in the test and a whopping 1783MB of RAM, making it too resource-intensive if your goal is to save battery.

So, if you’ve been looking for the most power-efficient browser, give it a shot with one of these.

Which browser is best for battery life?

Opera One – The most battery-efficient browser

Developed by Opera Software AS, the Opera One browser is known for its integrated ad-blocking feature and VPN.

That adds to its speed and performance while still being secure and private.

Not to mention, none of the above-mentioned features take up more resources of your device, since the browser has minimal impact on battery power.

Whether it’s streaming games or video, the browser can keep you going for a really long time.

It enforces security by protecting it from fraudulent sites, malware, and phishing attacks. The built-in ad blocker limits the ads which, in turn, leads to a really fast browsing experience.

UR Browser – Optimized for privacy and low impact on resources

UR browser is among the safest and most secure browsers out there though it’s also one that sips little battery juice, making it one of the best browsers for laptop battery life.

This is applicable even if you have multiple tabs open or when doing things that can be taxing on the CPU, such as watching a video or listening to music.

UR browser comes with a simple user interface that is easily customizable as well. You’ll get used to the UR browser easily given that it’s based on Chromium, the Google open-source platform that we already know.

Among other features, UR Browser has an integrated download tool that automatically identifies multimedia files on a webpage and can download those for offline viewing.

Microsoft Edge – Fastest browser with a low amount of features

The default browser from Microsoft for the Windows 10 platform also happens to be one of the best when it comes to battery life. Even though it is not the most energy-efficient browser, Edge is better than its predecessor.

Fortunately, that does not come at the cost of performance as the Edge is also one of the fastest browsers you can have in a Windows environment.

It is safe and secure too, having enough protection and privacy features onboard for you to carry on sensitive tasks such as banking operations with complete peace of mind.

It can ward off phishing or malware attacks and has the least likelihood of being hacked.

Edge is also constantly being upgraded to offer its users a smart experience. Developers too will find it easy to test their websites and online apps, besides allowing for a consistent experience across the board.

Brave Browser – Stable browser that doesn’t affect your CPU that much

Brave is a free web browser with ad-blocking being its biggest USP, something that naturally translates to better browsing speeds.

No wonder the company claims to have up to 8-times the speed advantage over contemporary browsers such as Chrome. That said, the browser is also known to provide an extended battery experience as well.

Whether playing online games or streaming video, the Brave browser is one that won’t let you down in terms of battery life.

Another key feature of Brave is the secured environment it provides for you to carry on with your browsing. Apart from ads, Brave also blocks the tens of trackers that are often present on even the most popular of sites.

The company takes pride in the ad-blocking and data optimization abilities of the browser which it claims can help save a lot of data and hence money in the process.

Mozilla Firefox – Expanded customization with a large number of addons

Firefox, developed by Mozilla Foundation and Mozilla Corp., is among the most popular browsers today.

Much of that has to do with its ability to perform with very little battery power while still being extremely secure and fast.

The browser also supports a host of plugins that further adds to the browser’s appeal.

It is also less intensive on the PC’s resources, with the company claiming it to be 30% lighter on the RAM than Chrome.

The company has also launched the Firefox Quantum, which claims to be the epitome of security, privacy, and speed while also being incredibly light on the battery.

It also offers several themes that allow you to personalize your browsing experience, while the thousands of extensions it supports only adds to the browser’s appeal.
