They aim to perceive users\u2019 real-time context like his\/her location, actions, or even emotion, and to provide various customized services based on the inferred context. However, context-awareness in mobile environments has some challenging issues due to limitations of devices themselves. Limited power is regarded as the most critical problem in context-awareness on smartphones. Many studies have tried to develop low-power methods, but most of them have focused on the power consumption of H\/W modules of smartphones such as CPU and LCD. Only a few research papers have recently started to present some S\/W-based approaches to improve the power consumption. That is, previous works did not consider energy consumed by context-awareness of Apps. Therefore, in this paper, we focus on the power consumption of context-aware Apps. We analyze the characteristics of context-aware Apps in a perspective of the power consumption, and then define two main factors which significantly influence the power consumption: a sort of context that context-aware Apps require for their services and a type of ways that a user uses them. The experimental result shows the reasonability and the possibility to develop  low-power methods based on our analysis. That is, our analysis presented in this paper will be a foundation for energy-efficient context-aware services in mobile environments.<\/jats:p>","DOI":"10.3390\/info5040612","type":"journal-article","created":{"date-parts":[[2014,11,17]],"date-time":"2014-11-17T03:15:21Z","timestamp":1416194121000},"page":"612-621","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Analysis of Characteristics of Power Consumption for  Context-Aware Mobile Applications"],"prefix":"10.3390","volume":"5","author":[{"given":"Meeyeon","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, Ajou University, 206, World cup-ro,  Yeongtong-gu, Suwon-si, Gyeonggi-do 443-749, Korea"}]},{"given":"Deok-Ki","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Ajou University, 206, World cup-ro,  Yeongtong-gu, Suwon-si, Gyeonggi-do 443-749, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8922-063X","authenticated-orcid":false,"given":"Jung-Won","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Ajou University, 206, World cup-ro,  Yeongtong-gu, Suwon-si, Gyeonggi-do 443-749, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2014,11,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"333","DOI":"10.3745\/JIPS.2013.9.2.333","article-title":"Adaptive Cross-Device Gait Recognition Using a Mobile Accelerometer","volume":"9","author":"Hoang","year":"2013","journal-title":"J.
