iCloud Photos synchronizes image and movies across all your linked Apple devices that have the feature enabled . It can sometimes be recalcitrant , requiring a real kickto resume syncing . But exposure should upload and download waiting line exposure via iCloud almost any time it ’s plug into to a internet , and there ’s enough powerfulness remaining in your iPhone , iPad , or Mac laptop computer .

There ’s an elision , though that ’s hard to spot : when you ’re using cellular data from your iPhone or iPad to your Mac via USB . It ’s seemingly not a democratic choice , as most people rely on the Personal Hotspot feature film that countenance you tie via Wi - Fi to your iPhone or iPad : no cable television require . However , I ’m a fan of plug in a USB - light speed to Lightning cable to level my iPhone while using a cellular web connection . I line up it more reliable , and I do n’t pass out of juice during the sometimes heavy power draw required to relay cellular datum .

In testing during a contrive electrical outage at my house to upgrade service , I chance on that iCloud Photos refused to synchronize while link via USB . The solution was simple : click the Control Center menu icon , click the justly - repoint arrow next to the Wi - Fi section , and select your iPhone or iPad ’s Personal Hotspot . Once connected , sync starts immediately .
