Learn practical tips to maximize battery life on your refurbished Shokz OpenFit earbuds, including charging habits, storage, and maintenance steps.
Quick answer
To extend battery life on your refurbished OpenFit, avoid deep discharges, store them at moderate temperatures, and use partial charging cycles.
Why refurbished earbuds need extra battery care
Refurbished earbuds may have a slightly different battery history than new ones, so gentle charging habits help preserve long-term capacity. The OpenFit's open-ear design is ultra-lightweight, but its battery benefits from the same care as any lithium-ion device.
A common misconception is that you should always drain the battery to zero before charging. For modern lithium-ion batteries, partial charges are actually healthier.
Steps to extend battery life on refurbished OpenFit
- Charge between 20% and 80%: Plug in your OpenFit when the battery drops to around 20%, and unplug once it reaches 80%. This avoids the stress of full charge or deep discharge cycles. Partial charges are better than full 0-100% cycles for lithium-ion longevity.
- Avoid extreme temperatures: Do not leave your OpenFit in direct sunlight, a hot car, or freezing conditions. Store them at room temperature (60-75°F / 15-24°C) when not in use. Heat accelerates battery degradation; cold can temporarily reduce capacity.
- Use the charging case correctly: Always place the earbuds securely in the case with the charging contacts aligned. The case itself should be charged with the included cable, not a fast charger unless specified. Misaligned contacts can cause intermittent charging and reduce effective battery life.
- Store at 50% charge for long periods: If you won't use your OpenFit for a week or more, store them in the case at about 50% charge. This minimizes stress on the battery cells. Storing fully charged or fully drained for weeks can permanently reduce capacity.
- Keep firmware updated: Connect your OpenFit to the Shokz app and check for firmware updates. Updates sometimes include power management optimizations. An outdated firmware may miss battery efficiency improvements.
