About
Mobile phone performance ratings were gathered from various evaluation aspects. The data focuses on assessing mobile devices across five key performance areas: the primary camera system, front-facing (selfie) capabilities, audio quality, display performance, and battery efficiency. This data product serves as an important resource for exploring the objective technical performance of specific phone models over time.
Columns
- model: The designation of the specific phone model, with 223 unique entries recorded.
- price: The associated price of the device, stated in US Dollars. Highly common prices include $799 and $699.
- launch: The date the mobile phone was introduced to the market, with records spanning from September 2013 up to January 2022.
- camera: The assigned rating for the primary camera system, with scores ranging from 56 to 144. This column is valid for 83% of records.
- selfie: The rating for the front camera performance. Scores range from 22 to 106, though data is available for only 32% of records.
- audio: The rating pertaining to the device's audio output and recording quality, with scores between 41 and 81. This metric is available for 42% of the models.
- display: The rating for the visual display quality, where scores range from 43 to 99. This column has a significant amount of missing data, being valid for only 29% of the records.
- battery: The rating reflecting the battery's longevity and performance, with scores between 49 and 96. This metric is the most sparsely populated, valid for only 24% of the records.
Distribution
The data is structured as a tabular file containing 8 columns and a total of 223 records. All identifying columns (model, price, launch) are 100% valid. However, the performance rating columns exhibit high rates of missing data; for instance, 76% of records lack a battery rating, and 71% lack a display rating.
Usage
The data is suitable for analysing how mobile phone performance metrics have evolved over time, tracking trends between September 2013 and January 2022. It can be used for building clustering models to group phones based on specific performance strengths (e.g., identifying devices that score highly in audio quality versus those that prioritise battery life). It is also useful for general benchmarking studies of mobile device technology.
Coverage
The data includes 223 unique phone models launched across a time frame beginning September 1, 2013, and concluding January 1, 2022. This temporal scope permits analyses of long-term technology development. Coverage is inconsistent across the performance metrics; many key ratings, particularly for battery and display, are unavailable for the majority of the phone models listed.
