The difference between iphone5 and iphone5s

Reference:
http://www.everymac.com/systems/apple/iphone/iphone-faq/differences-between-iphone-5c-iphone-5s-iphone-5.html

Internal Differences

The iPhone 5 and iPhone 5c are both powered by a dual core 1.3 GHz Apple A6 processor and have 1 GB of RAM.
Apple notes that the iPhone 5s has a 64-bit "Apple A7" processor and an "M7 motion coprocessor." Apple does not provide additional technical details, but the always excellent AnandTech was first to determine that the Apple A7 processor is a ARMv8 derivative of Apple's "Swift" dual core architecture called "Cyclone" and it runs at 1.3 GHz. It also is 28 nm, has a 64k/64k level 1 (instruction/data) cache and a 1 MB level 2 cache. AnandTech reported that the iPhone 5s models have 1 GB of RAM, too.
The iPhone 5 and iPhone 5s have 16 GB, 32 GB, or 64 GB of flash storage whereas the iPhone 5c have 8 GB, 16 GB, or 32 GB.
Originally, the iPhone 5c models shipped with 16 GB or 32 GB of storage, but on March 18, 2014, Apple added an 8 GB option, only in the UK, France, Germany, Australia, and China. On April 16, 2014, as first spotted by 9to5Mac, Apple quietly added the 8 GB iPhone 5c model in Austria, Belgium, the Czech Republic, Denmark, Finland, Hungary, Italy, Ireland, Luxembourg, the Netherlands, Norway, Poland, Portugal, Spain, Sweden, and Switzerland.
On September 9, 2014, Apple rolled out the 8 GB configuration of the iPhone 5c worldwide and discontinued the 16 GB and 32 GB options. Apple also discontinued the 64 GB configurations of the iPhone 5s. On September 9, 2015, Apple discontinued the iPhone 5c altogether.
Consequently, the currently shipping iPhone 5s models only have 16 GB or 32 GB of storage. Of course, on the used market, all other capacities are available, too.

iOS Support Differences

The iPhone 5 models fully support iOS 6, iOS 7, iOS 8, and iOS 9 but the iPhone 5c and iPhone 5s models only support iOS 7, iOS 8, and iOS 9, without any support for earlier versions of the iOS. However, note that if any of these iPhone models have been updated to a later version of the iOS it is not simple to "downgrade" to an earlier version without resorting to "jailbreaks" or other hacks.

3.1 Static techniques and the test process

Terms

Dynamic testing, static testing

During static testing, software products are examined manually, or with a set of tools, but not executed.

Background

Any software work product can be reviewed, including requirements specifications, design specifications, code, test plans, test specifications, test cases, test scripts, user guides or web pages.

Advantages:

- Start static testing early in the life cycle, early feedback on quality issues can be established. Ex an early validation of user requirements.
- By detecting defects at an early stage, rework costs are most often relatively low and thus a relatively cheap improvement of the quality of software products can be achieved.
- Since rework effort is substantially reduced, development productivity figures are likely to increase.
- There is an exchange of information between the participants.
Static test contribute to an increased awareness of quality issues.

In conclusion, the quality improvement is not achieved once but has more structural character. The feedback from the static testing process to the development process allows for process improvement, which supports the avoidance of similar errors being made in the future.
