How to properly charge your laptop to make the battery last longer
Several practical habits that significantly affect the longevity of a lithium-ion battery.
The main principle: avoid extremes
Lithium-ion batteries perform best in the range of approximately 20-80% charge — constant discharge to 0% or keeping at 100% under constant power accelerates wear more than moderate use in the middle range.
Is it harmful to work from the mains constantly?
Modern laptops have overcharge protection, so short-term operation from the mains at 100% is not critical. But constant operation "always connected, always 100%" for years — accelerates wear compared to periodic use on battery.
Temperature matters
Charging in a hot environment (direct sun, closed bag with poor ventilation) accelerates chemical wear of the battery more than the fact of charging itself.
Do I need to fully discharge before each charge?
No, this is an outdated myth from the era of nickel-cadmium batteries. For modern lithium-ion batteries, frequent partial recharges do not harm, unlike regular full discharge to zero.
How is this related to the warranty?
Lapto.de guarantees the residual capacity of the battery at the time of sale (more details in a separate article), and adhering to these habits helps maintain this condition longer after purchase.
