The article contains the most important points on methods of maintaining the battery level of a laptop for users of all levels. What happens if you recharge your laptop battery? The short answer is: nothing. If you forget your laptop while charging after it is fully charged, nothing will happen to it.
Li-ion batteries
Most modern computers run on lithium-ion batteries. They can be recharged hundreds of times without affecting battery life. Inside there is a cycle that stops the charging process when the battery is fully charged. Without this cycle, it would heat up during charging and could easily burn out. Such batteries should not heat up, if this happens, then you have a defective product.
Nickel Cadmium
Older generation laptops run 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 extend its life. As with lithium-ion batteries, if left oncharging after fully charged, it will not affect their life in any way.
Batteries on Macbooks
Apple makes devices with built-in lithium-ion polymer batteries to save space and keep the device compact. To check the battery status, you need to press the Option button and click on the battery level indicator in the quick access toolbar. Several messages may appear after:
- "Replace soon" - the battery is functioning 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 condition of the battery can negatively affect performance, so you need to take the computer to an Apple Authorized Service to have it replaced.
- "Show service" - the battery is functioning normally. Macbook can be used when plugged in.
Saving energy in Windows 10
In Windows 10, the power saving mode automatically turns on when the laptop battery level reaches 20%. Depending on the settings, the screen brightness is lowered to keep the battery level longer. To check this, go to "System and Security" in Control Panel, then to Power Options. All changes can be made manually. To save the battery,It is advised to keep bluetooth turned off at all times. If you are not using the Internet, you can temporarily put your laptop into Airplane Mode, which will significantly save your device's battery level.
Extend battery life
To prolong battery life, after purchase, leave the laptop on charge for 12 hours before use. Lithium-ion batteries can last longer if the battery level is constantly kept between 20-80%. Although continuous charging does not greatly affect lithium-ion batteries, it is still advised 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 more, remove the battery. If it is not removed, then the battery level should be left less than 50% before closing. If not charged for a long time, the battery may be damaged. High temperature fluctuations should also be avoided. Do not leave your computer in a closed car in hot summers under the sun or extremely cold winters.
Extend battery life
To extend battery life between recharges, you can:
- reduce screen brightness;
- set sleep time and screen off timer for a short time;
- turn off Wi-Fi and bluetooth;
- close unnecessary tasks in the "Dispatcher";
- close unnecessary browser tabs;
- do not block the air supply to the cooler (the battery runs out quickly when heated);
- extract unusedUSB cables and drives;
No battery has a lifetime warranty, so old batteries should be replaced with new ones from time to time. If the old one is still capable of holding a 15-20 minute charge, you can take it with you on long-term trips to replace it with another one in case of emergency.
Follow the tips to save battery life, avoid using your laptop plugged in all the time, then you will notice how amazingly long the battery lasts.
