June 29th 2007 the first iPhone came out; fast-forward to 21st of March 2016 apples iPhones have come a long way in a period of 9 years and today we take a look at the Evolution of iPhones.
The original iPhone
The original iPhone was launched on 29th June 2007 and was touted as the “Jesus phone” the iPhone however back then housed a 3.5 inch touch screen with a measly screen resolution of 320×480 pixel screen resolution. It ran a single core 412 MHz processor and had 128 MB of RAM. There was no front camera and a mere 2 MP rear camera which back then was a huge deal. It was priced at $499 for the 4 GB model and $599 for the 8 GB version. The original iPhone ran on the same Unix core used on Mac OS but the operating system was later renamed to iOS 1.
The iPhone 3G/3Gs
The 2nd generation iPhone dubbed as the iPhone 3G improved upon the shortcomings of the original iPhone and the iPhone 3gs took it to a whole new level. The iPhone 3G had almost the same hardware as the original iPhone but the iPhone 3Gs doubled the power as well as the memory and pretty much everything of the iPhone 3G. Assisted GPS was introduced along with faster connection speeds with 3G bands.
The iPhone 4/4s
The 4th generation of the iPhone bought with it a new all glass design which was soothing to look at, it also increased the power of the CPU from 600 MHz on the iPhone 3Gs to 1 GHz on the iPhone 4 while it doubled the number of cores on the iPhone 4s. It also doubled the RAM from 256 MB to 512 MB, also for the first time on an iPhone Apple introduced a front facing camera on the iPhone 4 which was mainly used for video chats. The display too was bumped up to 640 X 960 “Retina display” Steve Jobs said “Once you use a Retina Display, you can’t go back,”
The iPhone 5/5s/5c/SE
The iPhone 5 had a bigger screen, a better camera, a faster processor and more memory as anyone would expect but the iPhone 5s was the first phone at the time to come with a biometric fingerprint sensor which could be used to protect the device. The 5c on the other hand features a polycarbonate body and was aimed at the younger users. The iPhone SE which is the most recent entrant to the iPhone line up gives users the experience of the latest iPhone 6s in a smaller form factor.
The iPhone 6/6 Plus
In the wake of the phablet revolution Apple launched the iPhone 6 and iPhone 6 plus which featured a 4.7 inch display and a 5.5 inch display respectively. The retina display remained on the iPhone 6 while the 6 plus got a full HD display resolution. Both the phones still run dual core CPUs but with an improved and optimized architecture. The cameras too remained the same 8 MP ones albeit with larger pixel capture.
The iPhone 6s/6s Plus
The iPhone 6s/6s plus are the latest of the iPhones one can buy apart from the iPhone SE, the 6s and the 6s plus both house a new technology called the 3D touch which is a pressure sensitive touch technology along with better and improved 12 MP rear cameras along with 5 MP front ones.
The hardware on the phones have evolved so much from the first iPhones in 2007 to the current iPhone and yet it manages to keep things at minimal, the processors only gone up to a dual core while the RAM is at 2 GB if we compare this with the developments in Android we would see a massive difference between them because Android has reached to 8 and 10 cores and it’s still not enough while iPhone manage to outperform a lot of Android phones single handedly but why is it so? Optimization is the answer the software that Apple uses is optimized to such an extent that it doesn’t need that amount of hardware to perform humongous tasks.
Apple has really come a long way from a 412 MHz single core processor on the original iPhone to a dual core 1.84 GHz processor on the 6s and 6s+, with the new iPhones just around the corner we’ll have to wait to see what’s in store for us this year.
