A study involving over 1,500 Android phones, specifically Samsung Galaxy S3 and S4 models, utilized an app called eStar Energy Saver to monitor energy consumption. The research revealed that approximately 45% of battery drain occurs while the screen is inactive. A substantial portion of this energy is consumed by apps updating in the background, such as downloading headlines and weather information, and by the constant cellular paging process. Cellular paging, which involves the phone receiving pings from a cell tower every 1.28 seconds to check for incoming calls or messages, accounts for about 12% of the battery drain. The study also highlighted that different versions of the same app can have varying energy demands, with some versions of the Facebook app being twice as energy-intensive as others, suggesting that app version selection could influence battery life. The findings emphasize that actively managing background app activity and acknowledging the inherent energy cost of staying connected are crucial for optimizing smartphone battery performance.",{"@graph":69,"@context":105},[70,84],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/smartphone-battery-drains-a-lot-even-with-dark-screen/24724/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/smartphone-battery-drains-a-lot-even-with-dark-screen/24724.png","ImageObject",300,407,{"name":92,"@type":93},"Anda","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-09-19","2026-05-07",true,{"@type":102,"interactionType":103,"userInteractionCount":8},"InteractionCounter",{"@type":104},"ViewAction","https://schema.org",{"og:url":107,"og:type":108,"og:title":65,"og:site_name":95,"og:description":67},"https://docshare.wps.com/document/smartphone-battery-drains-a-lot-even-with-dark-screen/24724","article",{"robots":110,"canonical":107},"index,follow",{"doc_id":112,"site_id":62},24724,1778189647,{"code":4,"msg":5,"data":115},{"doc_id":112,"user_id":116,"nickname":92,"user_avatar":117,"doc_module":4,"category_id":29,"category_name":30,"doc_title":65,"doc_description":67,"doc_content":66,"file_id":118,"file_url":119,"file_type":120,"file_size":121,"view_count":8,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":8,"language":122,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":66,"faqs":66,"seo_title":123,"seo_description":67,"update_tm":113,"read_time":81},962075006959,"https://ap-avatar.wpscdn.com/avatar/e0002397efbe92a78e?_k=1776741047341049297","cbCaigMLjicRjyYV","https://ap.wps.com/l/cbCaigMLjicRjyYV","pdf",328313,"English","Smartphone Battery Drains a Lot Even with Dark Screen | PDF"]
