iOS 8 Downloads Cause Spike in Web Traffic as Adoption Rate Climbs Slowly

Apple yesterday released iOS 8 to the public, opening the doors for iPhone, iPad and iPod touch owners to download and install Apple's latest version of iOS on their devices. According to The Guardian, this release caused internet traffic to surge in the UK by as much as 60 percent compared to the same time the previous day as millions of iOS users rushed to update their devices.

iOS 8 adoption from Mixpanel

iOS 8 may have caused web traffic to briefly increase, but the first-day adoption rate of the mobile operating system is relatively low when compared to previous iOS rollouts. According to analytics firm Mixpanel, only 14 percent of the iOS devices that it tracks are currently running iOS 8. Data from mobile marketing company Fiksu shows a similar slow uptake in iOS 8 with the adoption of Apple's latest iOS version trailing the last that of the last several iOS launches.

The slower update rate may be due to a record number of iPhone owners purchasing new devices. Apple sold more than four million iPhone 6 and iPhone 6 Plus units in the first 24 hours that pre-orders were available last week. Customers who are receiving a new phone in the coming weeks may delay upgrading their current device, opting instead to prepare the handset for sale.

Another factor may be the large storage size required for the over-the-air updates. Though the iOS 8 update was just over 1 GB in size, it required 4.6 GB of free storage space on an iPhone and almost 7 GB of free storage on an iPad for installation. That's almost half the free space available on a 16 GB device, forcing many owners to decide whether to delete content from their devices or install the update.

The requirement of needing 5+ GB free on the device for a download that was less than 2 GB is the dumbest thing.

You do realize the update needs to be extracted, right? It's like downloading a zipped file on your computer and you need zip file space + extracted space on your computer to be able to extract it correctly.

No, it's because iOS 8 runs like crap on anything lower than an iPhone 5. iOS 8 is amazing on big screens, 3.5"...nah.

And millions of people still have a 4S.

Sounds far fetched to me. I think the share of iPhones that is not eligible for the iOS 8 update is much larger than the share of devices not eligible for the iOS 7 update was last year. The iPhone 4 was much more popular than the 3GS.
