BATTERY AND POWER
You can operate the XDV with or without the battery installed while the camera is attached to an AC or DC adapter or USB power bank. It also worked as a webcam with or without the battery.
The following are recording times with a fully charged battery. I only tested 4K and 2.7K because the other resolutions are so bad.
- 4K, display off, WiFi on: 74 minutes
- 2.7K, display on, WiFi off: 90 minutes
- Charging time, 2.0A AC adapter: 79 minutes
The charging time is very good, the best I’ve tested. The recording times are okay for 4K and 2.7K. The thing is, these are the only two usable resolutions. What if you want to record for a longer time at 1080p or even 720p? You could but the quality of those lower resolutions is essentially unusable so your maximum recording time is effectively limited to an hour-and-a-half at 2.7K (somewhat more if the display is off).
Like most other action cams, when I removed and replaced the camera’s battery the date and time reset to default. You can set them to current using the camera menu or by connecting to your mobile device then selecting date/time sync from the app menu.
