To ensure user satisfaction and success of mobile applications, it is important to provide highly performant applications. This is particularly important for resource-constrained systems such as mobile devices. Thereby, non-functional performance characteristics, such as energy and memory consumption, play an important role for user satisfaction. This paper provides a comprehensive survey of non-functional performance optimization for Android applications. We collected 156 unique publications, published between 2008 and 2020, that focus on the optimization of performance of mobile applications. We target our search at four performance characteristics: responsiveness, launch time, memory and energy consumption. For each performance characteristic, we categorize optimization approaches based on the method used in the corresponding publications. Furthermore, we identify research gaps in the literature for future work.

“…Some studies have attempted to eliminate unnecessary frame rendering for unchanged content. Lee [7] found that frames are unnecessarily rendered even if there is no change of content. His method compares the display lists needed to render the current frame with those used to render the previous frame.…”

“…The frame rate indicates the frequency of frame rendering operations per second (fps). However, the higher the frame rate, the larger the CPU and GPU usages of the graphics pipeline, which consequently increases power consumption [7,8].…”

“…There have been studies on saving power consumption from the perspective of the content changes in the Android graphics pipeline. Lee [7] displays a previously rendered frame instead of rendering a new frame if there was a high similarity among frames rendered in the recent past. However, that study cannot reduce power consumption in use patterns that cause a change in content, such as scrolling.…”

Scrolling-Aware Rendering to Reduce Frame Rates on Smartphones

et al. 2021

One of the major sources of power drain in smartphones is a frame rendering and display process called graphics pipeline, in which power consumption depends largely on frame rendering operations per second (fps), known as the frame rate, and the quantity of UI content to be rendered. We discovered a major problem causing power consumption upon a scrolling operation: The Android graphics pipeline renders all or a large portion of the content displayed most recently at a frame rate of nearly 60 fps. This paper proposes a scrolling-aware rendering (SCAR) scheme to reduce the frame rate caused by a scrolling. When rendering a frame for UI content to be displayed, SCAR pre-renders UI content that is likely to be displayed soon in any subsequent scrolling operation. This frame is extended to place the pre-rendered UI content contiguously with the UI content to be displayed. Upon a subsequent scrolling, SCAR repositions the extended frame on screen by a scrolling distance instead of rendering a new frame. Our experiments on a smartphone show that SCAR reduced frame rates to below one fps in scrolling, thus saving power by up to 30%.

This study looks into how force-intelligent wearable devices can be used to quantitatively manage daily physical activity levels. The study intends to investigate the effectiveness of these devices in measuring various physical activity metrics such as step count, distance walked, calories burned, and exercise intensity. A thorough methodology is used, which includes device selection, participant recruiting, data collecting, and analysis methods. Participants wear the selected wearable devices continuously for a set amount of time, enabling longitudinal tracking of daily physical activity patterns. The acquired data is evaluated using statistical analysis approaches such as descriptive statistics, correlation analysis, and cross-demographic group comparisons. The findings provide insights into participants' activity levels, device accuracy, user engagement, and relationships between various physical activity measures. The study's findings help to better understand the usefulness of force-intelligent wearable devices in promoting physical activity and improving health outcomes. Further research in this area could help to inform programs aimed at increasing physical activity and general well-being.
