This issue may come from various reasons:
1. You are using Pause Mode feature in Performance Mode:
a. With a fully charged holder, you can have the 3rd consecutive usage in Performance Mode (FlexBattery feature) if you do not use the Pause Mode for the first two usages.
b. If you use the Pause Mode, the device will only deliver 2 consecutive uses.
2. Holder is not fully charged:
a. Charge your holder by placing it in a charged pocket charger.
b. Note that the Touch Screen will not show 3rd available usage even if the holder is fully charged and the usage is available.
3. Device is outside the optimal temperature range:
a. If the holder is used outside the optimal temperature range (0°C - 40°C), the device may need to use more energy per use. This may discharge the battery more rapidly.
b. Bring the device to the optimal temperature range.
4. Humid sticks:
c. If the SMARTCORE STICKS™ are humid, the device may need to use more energy per use. This may discharge the battery more rapidly.
d. To store your SMARTCORE STICKS™ in the optimal conditions, keep them in a closed pack and do not expose to humidity or humid weather conditions.
5. Battery degradation:
a. The battery degradation may happen over time as for any other electronic device.
b. In this case, the replacement is not covered by the warranty.
