Google Photos will introduce an "Overnight backup" feature to improve media backup on Android devices, addressing issues caused by background restrictions like Doze mode. Users must keep the app open, connect their device to a charger, and keep the phone unlocked while the screen dims to black during uploads. The feature aims to provide a reliable backup solution for large volumes of media. Users will receive guidance through the process, including reminders to stay on the app and keep the device charged. They can choose to use Wi-Fi or mobile data for backups, with Wi-Fi as the default. The app will alert users if their device overheats during the process and will notify free-tier users nearing storage limits. The feature is not yet available but reflects Google’s commitment to enhancing user experience.
