Lenovo Vantage is the first place to check for charging limits and battery-related settings. It can explain why your battery stops at 80% and can provide health clues depending on your model.
What to check inside Lenovo Vantage
- Charging threshold / conservation mode: may cap charge at 60–80% to reduce wear.
- Battery status: look for warnings or abnormal charging behavior.
- Usage context: heavy heat/workloads can accelerate battery wear.

Compare Design Capacity vs Full Charge Capacity. A large gap + real symptoms usually means replacement is worthwhile.
If you need replacements
- Battery: match FRU/Part Number, V/Wh, connector.
- Charger: match connector type and wattage (USB-C PD vs Slim Tip vs round).
