Tips to Extend Your Battery’s Lifespan

1. Keep it cool – heat is the biggest cause of battery wear, so avoid leaving your Lenovo laptop in direct sun, a hot car, or on soft surfaces that block the vents.
2. Avoid charging to 100% every time – many Lenovo laptops have a battery conservation mode in Lenovo Vantage that limits charging to around 80%, which can roughly double your battery’s usable lifespan.
3. Don’t let it run flat – regularly draining the battery to 0% wears it out much faster than topping up before it gets critically low.
4. Store at around 50% charge – if you won’t be using the laptop for a few weeks or more, store it half-charged in a cool, dry place rather than fully charged or fully empty.
5. Go easy on fast charging – rapid chargers generate extra heat, so standard charging (especially overnight or while idle) is gentler on the battery over time.
