If you use Chrome on your iPhone or iPad, and you’re not running the latest version, you may want to update it. Google has started inviting selected users to enable the data-compression feature it first launched on Android back in March.
Or, in less technical terms, Chrome strips out everything not needed to display webpages properly, so you get the same experience but with up to 50% less data usage. For those who do a lot of browsing on 3G/4G, that can make a big difference to your monthly data bill.
So far, only a relatively small number of users appear to have been invited to participate, but that number is likely to grow over the next few weeks.
