Question

Is there any use of favicon.ico for mobile websites? will it be shown in browser address bar and tabs in mobile websites

We use apple icons <link rel="apple-touch-icon" href="/apple-touch-icon.png"/> in mobile websites. what about Android, Blackberry and Windows 7 phone? Is favicon.ico useful for other mobile phones other then iOS mobiles

Answer 1

Here is my study about icons:

Considering the tag: <link rel="apple-touch-icon" href="IMAGE-NAME" />

Considering the sizes:

57x57px default size

72x72px iPad size

114x114px Retina / Opera

Images:

'apple-touch-icon.png' - at iOS, in this image will applied the 'Gloss' effect. On other OS'es, nothing happens.

'apple-touch-icon-precomposed.png' - This image will not receive any effect

Here is the following tests on OS':

BlackBerry v6.0 or higher - Only works 'apple-touch-icon'

BlackBerry v5.9 or lower - Not supported

Android 2.2 or higher - Works both versions

Android 2.1 or lower - Only works 'apple-touch-icon-precomposed'

iOS 4.1 or lower - Works both versions

iOS 4.2 or higher - Works both versions and accept size attributes (and so, sizes different from 57x57px)

Nokia's (probably S60 5th FP1 and higher, not fully confirmed) - Some accept 'apple-touch-icon'

OperaMini (SpeedDial Shortcut) - Works both versions BUT must have at LEAST 114x114px (speed dial normally is 200x200px if i'm not mistaken.
