Here is Why you Laptop Batteries Don’t Last Long

Laptop manufacturers promise their devices last as long as 15 hours but you will be in luck if your laptop lasts up to 10 hours on a single charge. Well, manufacturer’s estimates aren’t wrong and free from any mistakes as most of the brands choose the most unrealistic and highest-quality benchmarks.

All laptop manufacturers are bound to advertise their only optimistic numbers to grab the attention of users. If any laptop maker believes in reality and advertises 7-9 hours of battery life, others come up with up to 15 and hence, a realistic manufacturer will get overlooked easily. It doesn’t mean manufacturers lie. The unbelievable Battery life numbers come from a legitimate benchmark and are lying in the twinkling of words.

Twinkling of Words like “Up To”

When it comes to buying, you will see the words like “Up To” in manufacturers’ user manuals. Let us be more accurate, manufacturers don’t promise 16 hours of battery life but up to 16 hours. These kinds of twinkling of words are quite common in all sorts of advertising. For example, a retailer or store says, users, can save “Up To” 50% which isn’t lying whether you save 10% or 20%. Let’s put another example when an internet service provides says a user will get “up to 40Mbps” which is technically true even if you get 10Mbps only.

Impossible to Estimate Exact Battery Life

No one can estimate the right amount of life even while using it. Normally, Windows indicate that you are going to have 5 hours of juice but in actual, you get only 2 hours – depends on what you do. That obviously means performing demanding tasks increase power consumption. Typically, laptops don’t consume too much power when watching videos at the lowest possible brightness. But if you start a demanding task like editing videos or using Photoshop, it’ll draw more power in less time.

Try Finding Real Benchmarks

Manufacturers do share their benchmarks but don’t reveal a method of testing. We don’t know which type of Adapter they use to charge fully and how much the level of brightness they use to test. Therefore, it’s a bold move not to rely on their benchmarks and find independent reviews of a laptop. You are about to buy or you have. Reviewers use a wide range of scenarios to benchmark laptops to see how batteries of laptops go through a simulated web browsing test which is more applicable to typical day-to-day use. Putting an example here, Microsoft claims its Surface Book 2 devices to last up to 17 hours. But normally, according to reviewers, they last only 9-10 hours that still appeal many.

Benchmarks are Based on Video Playback

Continues video playback doesn’t fall in the list of regular use. Is there is anyone who will sit on a chair and watch videos on a laptop for 16 hours without other activities.? Perhaps no one! It doesn’t matter to manufacturers whether or not this reflects your experience. But most of the manufacturers use this method to produce the longest life of the batteries.

Laptops with the latest and coolest technology use hardware-acceleration to play videos. The laptops are equipped with special hardware in their GPU that effectively decodes. The video without using too much power and CPU. So, if you are watching videos even on a website, it’ll kick into gear and wouldn’t use power a lot. It sounds an interesting feature and doesn’t only consume low power but also keeps your laptops running cool.

Laptop manufacturers use to benchmark the life of their batteries by using Movies & TV app on Windows 10 which is always configured to use the hardware acceleration. This feature isn’t present on all video players and cannot be enabled by default if it’s available. For instance, if you like watching videos or movies in VLC video player. You might need to get enabled hardware acceleration.
