The USB-C connector on the Venue Pro 8 (5855) can support data transfer or AC power but not both simultaneously. When it is connected to a USB port on a computer, it automatically switches to data transfer mode and will not charge the battery. To charge the device, always use the AC power adapter with the USB-to-USB-C cable supplied with the device. The USB-C connector is located on the bottom edge of the Dell Venue 8 Pro (5855) tablet (when held vertically with the webcam in the upper right-hand corner).
| LED status | What it means |
| Solid White | The battery is charging. |
| Solid Amber | The battery is at low level with the tablet on or in a connected standby state - the screen is off, but the tablet is still turned on. |
| Off | The battery is not charging, or the battery is fully charged. |
| Flashing Amber | The battery is at a critical level and does not have enough charge to power on. If the power button is pressed during this state, the LED will turn on for 3 seconds and then turn off. Continue charging the tablet. |
The battery normally requires about 4 hours to fully charge. The charge status can be checked from within the operating system.
