On your phone swipe the status bar down and open the Moto Mods Manager notification at the bottom of your notification list.
Or, press the button on the TurboPower Pack and look at the status light:

| Lights on | Meaning |
|---|---|
| 1 | 0-24% charged (light blinks if 1-5% charged) |
| 2 | 25-49% charged |
| 3 | 50-74% charged |
| 4 | 75-100% charged |
If the TurboPower Pack is charging, a solid light turns on for each completed charge level and a light blinks for the current charge level.
To see if the attached TurboPower Pack is charging your phone, look at the battery icon in the status bar at the top of your home screen:
| Attached battery charging phone. | |
| Connected charger charging phone. | |
| Attached battery not charging phone’s battery, which is fully charged. |
