Vacuum runs for only a few minutes on a full charge before shutting off.

Safety first: Use only genuine Samsung replacement batteries.

• Confirm charge: Fully charge the battery until the indicator shows 100% or all bars lit.
• Test on lower power: Run the vacuum on low or medium mode. If runtime improves significantly compared to max mode, the battery is weak but still partially usable.
• Check battery age: If the battery is more than 2–3 years old or heavily used, reduced runtime is expected.
• Replace battery: Purchase a compatible Samsung battery pack for your model and replace the old one. Dispose of the old battery at an appropriate recycling facility.
