BEFORE USING
Calibrate the battery
To make sure the battery percentage reading is correct, make sure to calibrate the battery within the first seven days of receiving the product.
It’s easy to do. Follow these steps:
- Fully discharge Omnicharge until the screen turns off. Press the Power Button and you should see an empty battery icon on the screen.

- Fully charge your Omnicharge to 100% to finish the calibration.

Note: The Omnicharge battery needs to be recharged at least every 6 months to avoid over depletion. Failure to do so can cause the battery to malfunction and is not covered by warranty.
Note: For optimal wireless charging, place the phone horizontally towards the back of the Omnicharge.
