Does syncing Phone Link over mobile data consume a lot of battery?
Yes, keeping a constant connection over cellular data requires more power than Wi-Fi. Your phone may drain faster because it must maintain a steady signal to the cellular tower while syncing data to your PC. We recommend keeping a charger nearby if you plan to sync for long periods.
Why is my Phone Link not syncing photos over cellular data?
This is usually caused by background data restrictions. Check your phoneās app settings to ensure āAllow background data usageā is enabled for the Link to Windows app. Also, verify that your mobile data plan is active and not currently in a low-data state or restricted by your carrier.
