Modern smartphones typically use resolutions between 1080×2340 and 1440×3120 pixels. For OLED/AMOLED displays (common on Samsung Galaxy and newer iPhones), consider choosing dark or black wallpapers to save battery life - true black pixels are turned off on OLED screens, reducing power consumption by up to 40%.
On iPhone (iOS 17+), long-press the Lock Screen → Customize → tap the wallpaper area → Photo → select your downloaded image. On Android, long-press the home screen → Wallpapers → My Photos → select the image. You can usually set separate wallpapers for the lock screen and home screen.
