Remove Battery When Plugged in? Not Really. Temperatures don’t just mean the ambient temperature, but the temperature of the battery which might also be affected if your laptop is kept somewhere where heat is being trapped - such as a pillow or at a not very well ventilated spot. Operating your laptop at high temperatures while plugged in at 100% battery charge isn’t recommended as well. The study concluded that the optimal charge voltage for Lithium batteries is 3.92v/cell which is roughly equivalent to 60% of battery charge. But this will also mean that battery won’t last as long on a single charge. Similarly, an even lower charge at 70-75% (4v charge/cell) will quadruple the discharge cycles. Improve the Battery Discharge CycleĪccording to a study by the Battery University, you can prolong your battery’s discharge cycle by not charging it to 100% (4.2v charge/cell).īased on the table below, charging your battery to 85-90% will double its discharge cycle from 300-500 to 600-1000.

High voltage levels while charging can shorten a battery’s life and temperatures over 30° celsius can severely damage the battery too. Lithium batteries are known for their unstable properties and there are a number of factors like voltage level, temperature and the number of times they have been recharged which contribute to their deteriorating quality over a period of time. However, the answer to keeping your laptop plugged in isn’t as straightforward because it depends on a number of factors. Keeping your battery in a discharged state for long periods can damage its potential to fully charge again or charge at all. While overcharging isn’t a possibility, keeping your laptop battery discharged is an issue. Two types of batteries - Lithium-ion and Lithium-polymer - are prominently used to power all new laptops worldwide and although they are built using different tech, they function in similar ways.īut does it hurt the battery life if you charge it while using it?Ī lithium-based battery can not be overcharged even if you leave it plugged in at all times because as soon as it is fully charged (100%), the internal circuit prevents further charging until there is a drop in the voltage. While there are a number of things you can do to improve your battery life, it’s unclear whether you should be using your laptop while it’s plugged in or on battery power.Įvery battery can only sustain a finite number of charge and discharge cycles, after which it starts wearing off quickly.

This is a question which has been debated for long without any definitive answer.

Using laptop without battery
