The article contains the most important points on the methods of preserving the laptop battery level for users of all levels. What happens if I recharge my laptop battery? The answer is as short as possible: nothing. If you forget the laptop on charge after fully charged, nothing will happen to it.
Lithium ion batteries
Most modern computers run on lithium-ion batteries. They can be recharged hundreds of times without affecting the long-term battery life. Inside there is a cycle that stops the charging process when the battery is fully charged. Without this cycle, it would have warmed up during charging and could easily burn out. Such batteries should not heat up, if this happens, it means that you have a defective product.
Nickel cadmium
The older generation of laptops runs on nickel-cadmium batteries. They require more frequent repair and replacement than lithium-ion. Once a month, the battery should be fully charged and discharged, this helps to prolong its existence. As in lithium-ion batteries, if left on charge after fully charged, this will not affect their service life.
Batteries on MacBooks
Apple manufactures devices with built-in lithium-ion polymer batteries to preserve the space and compactness of the device. To check the battery status, click on the Option button and click on the battery level indicator in the quick access panel. After that, several messages may appear:
- “Replace soon” - the battery functions normally, but holds less charge than when it was new.
- “Replace urgently” - the part functions normally, but holds significantly less charge than when it was new. The computer will work, but the state of the battery can negatively affect the performance, so you need to take the computer to an authorized Apple service to change it.
- “Show service” - the battery is functioning normally. The MacBook can be used when it is connected to an electrical network.
Saving energy in Windows 10
In Windows 10, the power saving mode is automatically turned on when the laptop battery level reaches 20%. Depending on the settings, the screen brightness is lowered to preserve the charge level for longer. To check this, go to "System and Security" in the control panel, then in the power settings. All changes can be made manually. To save the battery, it is advisable to keep the bluetooth off at all times. If you do not use the Internet, you can temporarily put the laptop in the “Airplane Mode” state, which will significantly save the device’s charge level.
Extended Battery Life
To extend battery life, leave your laptop charged for 12 hours after use before you buy it. Lithium-ion can last longer if the battery level is constantly kept between 20-80%. Although constant charging does not greatly affect lithium-ion batteries, it is still advisable to remove it if the laptop is constantly connected to the network.
If you are not going to use the laptop for a month or longer, then remove the battery. If it is not removed, then the battery level should be left less than 50% before closing. If the battery is not charged for a long time, the battery may be damaged. High temperature extremes should also be avoided. Do not leave the computer in a closed car in hot summers in the sun or in too frosty winters.
Extended Battery Life
To extend the battery life between charges, you can:
- reduce screen brightness;
- set the time for sleep mode and the screen off timer for a short time;
- disable Wi-Fi and bluetooth;
- close unnecessary tasks in the "Manager";
- close unnecessary tabs in the browser;
- Do not block the air access to the cooler (the battery dies quickly when heated);
- remove unused USB cables and drives;
No battery has a lifetime warranty, so from time to time old batteries should be replaced with new ones. If the old one is still able to hold 15-20 minutes of charging, you can take it with you on long trips to replace it with another in case of emergency.
Follow the tips to save battery life, avoid using a laptop connected all the time to the network, then you will notice how amazingly long the battery lasts.
