🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Restore the reliable battery performance of your Ulefone 3289 with this 3289 6000mAh replacement battery. The Ulefone 3289 is a daily-use phone designed for calls, social apps, photos, and mobile work.

Using an incorrect battery model may cause improper fit, charging issues, or incorrect battery reporting.
Battery Care Tips: Use a compatible charger, avoid extreme heat or cold, and try not to drain the battery to 0% often. For daily use, keep the battery level between 20% and 80% when possible. If you store the phone for a long time, keep the battery at around 50%. After replacing the battery, check that the back cover is closed correctly. If your Ulefone 3289 is a water-resistant model, water resistance depends on the back cover seal. Make sure the rubber gasket is clean and intact, or install a new seal, and close the cover properly. If you are not confident, ask a professional technician to do the replacement.
