New York, Dec 28: For most apple users it may come as a surprise that their phones being run on iOS 10 have the capacity to automatically search and tag people and objects in a locally automated search rather than using I cloud. 
 
"Both Google and Apple's services use 'computer vision' to detect what's in photos. But on the iPhone it's incredibly easy to pick a subject, let's say 'cats' and search your photo library for images that feature a cat," Fortune reported on Wednesday. 
 
To save you on battery, iOS only does this when the phone is charging. Whenever you capture a new image, Apple's Image Signal Processor is able to detect objects and people, and will then look them up against its inbuilt database. 
 
To try this hidden feature, open the Photos app and tap on the search magnifying glass.  Users can tell Apple Photos who appears in your images and it should then be able to look and identify those people again.

With Apple making the experience of every new phone it launches unique the users are already the tricks around the newly launched iPhone 7 to understand the various tricks of the device to save time and effort.
