Common questions users of laptops often ask is how to extend its battery life or at least reduce its recurrence.
Although all batteries deteriorate over time, many laptop users question whether the way we use them can make a difference in their performance. Be usable.
If so, how do we use batteries? Should we keep them 100% charged at all times or plug and remove them according to their charging level?
Battery life
Batteries for mobile phones and laptop computers are mostly made of lithium.
Ashley Rolf, chief technology officer for technology company Lenovo in Ireland and the United Kingdom, says: Ten years ago, the performance of laptop batteries began to decline after being charged a few hundred times.
"But now laptop batteries typically last three to five years, during which they can be charged five hundred to a thousand times."
"You want the battery to give you as much energy as you can charge and work for three to five years," Kent Griffith, a researcher in energy technology at Northwestern University, told BBC World.
How to achieve this balance?
Rolf of technology company Lenovo says that it is very safe and normal to keep your laptop connected to electricity at all times and keep the battery 100 percent charged at all times.
Laptop computers manufactured by Lenovo or other companies use sensors and control logic to ensure that the laptop's battery is not overcharged or overheated, he explained.
"However, keeping the battery on charge in the least times and keeping it at one hundred pc reduces its life," he added.
Lenovo's director of strategic technology and principal engineer agrees, saying: 'S performance decreases faster than usual and their battery life is shorter.
Explaining this, T. Griffith says, "This is because when a battery is 100 percent charged, it has the highest conditioning because the higher the energy, the higher the voltage."
Computer technology company HP thinks so. The company told the current International "HP does not recommend fitting the laptop with an electrical plug at all times."
HP says that most batteries today have the technology to prevent overcharging when they are 100 percent charged, but this technology cannot control the high voltage that puts extra pressure on the battery. And affects its performance ahead of schedule.
Similarly, Kent Griffith says, "So if you take the battery out of your laptop or any other device before it's 100 percent charged, your battery will definitely last longer."
These experts recommend limiting the laptop to fully charging or charging up to 80 percent of the battery whenever you plug it in, instead of charging the battery to 100 percent. ۔
"Technically, batteries are more 'happy' at 50 percent charge than zero or 100 percent charge, so technicians say it's best to keep them between 20 and 80 percent charged," says Rolf.
Similarly, technology expert Jacques says that "there are many benefits to limiting the pressure on batteries at 80% charge."
Microsoft has also warned on its website that the batteries used in its Surface laptops (not for other brands) will "lose their performance faster if they are overcharged."
"You can prevent your Surface laptop batteries from deteriorating too fast by not charging them too long," says Microsoft. If you need to charge the battery continuously, we suggest you use the battery charging limit mode.
Many brands such as Microsoft, Lenovo, and HP offer the option to limit the maximum amount of load on its battery in their laptop features.
For instance, HP gives you the option of charging up to a maximum of 80% in 'battery health' mode.
"In general, if you want to make your battery last longer, use it up to 80 percent instead of 100 percent, which will increase its charging cycle," says Griffith.
That is to say, in order to make your battery usable for a longer period of time, you need to strike a balance between how long your battery lasts and how many times you charge it.
How will you use your laptop?
But these expert recommendations do not mean that every time your laptop is 100 percent charged, you should immediately remove it from charging.
"All laptops have a control circuit to prevent the battery from overcharging, but you can increase the usable life of your battery by up to 80% by charging," said Rolph of Innovo.
But at the same time, he says, "batteries last longer these days, which may not be a problem for many consumers."
"Today's batteries are so good that they usually last longer than laptops," he said.
Rolf's final recommendation is how you test the laptop, ie, whether you have permanent access to the plug or if you haven't been connected to electricity for a long time. Otherwise, it would be better for you to fully charge it.
"Set the load limit on the battery if you're on your desk most of the time, but if you're out most of the time, leave it at 100% charge, and don't worry about it!"
