iOS 4 Adoption on iPhones Hits 50%


The research arm of mobile advertising and analytics firm Chitika yesterday announced that according to data pulled from the broad range of iPhone devices accessing its network, 50% of the ad impressions on the iPhone are now coming from devices running iOS 4.

Apple's latest mobile operating system, iOS 4, is already accounting for one-half of all iPhone web traffic, according to online advertising network Chitika. In looking at over 9 million iPhone impressions across its advertising network, Chitika found that iOS 4 edged iOS 3 by eight-tenths of a percent to be the dominant OS only one month after being officially released.

Only 5% of users, however, have updated to Apple's latest iOS 4.0.1, which was released on June 15th. But that statistic may be slightly misleading, as Chitika's Dan Ruby tells us that the data was collected from June 13th through 19th, meaning that iOS 4.0.1 was not even available for a portion of the survey period.

It is also important to note that not all iPhones are even capable of running iOS 4, with the original iPhone being completely unsupported and the iPhone 3G missing support for a number of key features such as multitasking, which reduces the incentive for those owners to update.

I think you meant 4.0.1 was released on July 15...

Except, not really:

The actual report, though, shows that 50% of iPhones with installed apps using one particular ad company's banners are using iOS 4


What the report does do is give a snapshot of how a certain subset of users - ones who regularly download and install apps - are keeping current with iOS updates.

Yeah because Chitika is know to produce reliable information. Eg, their Ipad tracking that indicated like double the real shipments several times and they just refused to believe that their method was dead wrong :D

The article should read July 13th through July 19th - not June.

I know, I know - time is flying by this summer.

I never bothered to update my iPhone 3G to iOS4. I thought it would slow it down. Yesterday, I picked up my iPhone 4 from the Apple Store. iOS4 is great on the iPhone 4. But my iPhone 3G still hasn't been upgraded and I don't think I'll ever update it to iOS4. I'm afraid it will slow it down.

I installed iOS4 on my 3G right away and it was great. Definitely not slower in any way, and I still got to use all of the new features besides multitasking and orientation lock. I did get an iPhone 4, but my sister is using the 3G with iOS4 every day and neither of us have noticed any problems.

Contacts, calendar and safari take much longer to load on my touch. The wikipedia search is cool but it takes about 5 seconds for anything I type to come up on the screen

So definite slowdowns and almost no new goodies here.

Can't confirm it - but it certainly seems like iOS4 on my 3G has reduced battery life.
