Requirements gathering on android and iphone smartphones



Requirements gathering is a vital process in any project. When timelines are thin, the scope is creeping, and budgets are economical, conducting a gathering process helps speed up efficiency. Disregarding this process means skipping a needed point of reference for balances and checks for the future. To collect requirements on iOS and Android phones, functional and non-functional features are analyzed; with the improvement of Android’s security in the recent releases, it’s prudent to pick a combination of both phones for a family.

Functional Requirements

Functional requirements define what smartphones should do.

  • Calling: Calling is an essential phone feature involving attempting or speaking to someone on the phone. Both iOS and Android phones would be able to do this.
  • Emailing: Entails sending of emails and using phone apps. Both two operating systems will be able to perform this.
  • Photography: Both iOS and Android phones would be able to do this. However, it depends on the quality of the specific phone’s camera lenses. Apple phones tend to have the edge over Android ones on this.
  • Voice activation: Both two operating systems have advanced this feature, and it works very accurately. The user can utter words that the phone picks and takes action eg uttering ‘Lock screen,’ making the phone lock. However, Android’s voice activation slightly edges out iPhone’s Siri.
  • Notifications: A user should get an alert on every activity going on in their phone. Both phones can perform optimum on this.

Non-functional Requirements

Functional requirements define how the smartphone should work. These requirements describe more to the user how they will perform in their environment.

  • Access to network: Every phone requires network access to operate; the strength they are built with dictates network access strength. Both phones can be good at this. A basic wireless plan is enough to use both phones.
  • Battery life and recharge duration: Apple phones are fast-charged compared to Android ones, with an average of one hour to recharge the phone while taking about 3 hours to recharge Android ones. On the opposite, Android phone’s batteries like Samsung can last longer with power than iPhones.
  • Speed: Generally, iOS phones perform better than Android ones. Apple phones perform optimization between software and hardware as opposed to androids on visible specifications without optimization.
  • Storage: iOS phones don’t come with an SD card slot while android phones do; therefore, upgrading storage to accommodate more files is only possible in androids if the initial space is used up.
  • Simplicity: With moderate or few applications, iPhone screens are straightforward to navigate usage more than the drawers of Android.


Android produces better phones based on functional and non-functional features such as storage, speed, battery life, and voice activation. However, several Android phones exist in the market with inferior functionalities and performances; therefore, to beat iPhone 12 Pro Max, it must be a superior Android like Samsung Galaxy S21 Ultra. Nonetheless, I would recommend a combination of both the phones distributed among the family members.


Both Android and iOS phones are in a stifling competition, and deciding to purchase one could be difficult. Various companies produce Android phones; therefore, there are many of them in the market, some inferior, others superior, while on the other hand, iOS solely makes iPhones’ stable operating system. Some features can be used to analyze the two categories like calling, emailing, voice activation, photography, notifications as functional ones and access to the network, battery life, speed, storage, and simplicity as features defining how the phones work.
