Eggheads astatine Vrije Universiteit (VU) successful nan Netherlands urge that group pinch Android devices usage autochthonal apps alternatively than web apps erstwhile viewing celebrated sites for illustration ESPN, Pinterest, Spotify, and YouTube because autochthonal apps are much power efficient.
That whitethorn look evident to immoderate but you cognize what they say: nan quality betwixt subject and screwing astir is penning it down.
In a preprint paper titled, "Native vs Web Apps: Comparing nan Energy Consumption and Performance of Android Apps and their Web Counterparts," machine scientists Ruben Horn, Abdellah Lahnaoui, Edgardo Reinoso, Sicheng Peng, Vadim Isakov, Tanjina Islam, and Ivano Malavolta analyse nan power usage of 10 net contented platforms that connection entree done some autochthonal Android apps and nan web.
The researchers looked astatine ESPN, The Weather Channel, LinkedIn, Pinterest, Coupang, Shopee, SoundCloud, Spotify, Twitch, and YouTube. They compared nan autochthonal Android apps and web apps for each of these successful position of power consumption, web postulation volume, CPU load, representation load, and clip betwixt video framework loads.
And they recovered that autochthonal apps usage little energy, arsenic tin beryllium seen from these mean values:
- Energy (joules):
- Native: 371.1275
- Web: 567.4365
- Network postulation (bytes):
- Native: 39,422,545
- Web: 21,956,270
- CPU utilization (percentage):
- Native: 24.22059
- Web: 35.89417
- Memory load (kB):
- Native: 238,682.8
- Web: 1,756,048
- Frame clip (ns):
- Native: 12,205,412
- Web: 13,691,591
While web apps usage much power than autochthonal apps, they besides nonstop and person little web traffic. The researchers posit this whitethorn beryllium a consequence of web devs being incentivized to trim bandwidth usage because web apps often person to beryllium reloaded connected startup.
They besides statement nan important quality successful mean representation load, pinch web apps demanding conscionable complete 1.5 GB much representation than their autochthonal counterparts.
"A imaginable mentation for nan representation overhead could beryllium nan truth that Web apps tally connected apical of nan Google Chrome browser app," they observe. "Since nan representation footprint of nan browser contributes to nan measurements, it is plausible that nan measurements for nan Web apps are higher than those of nan autochthonal versions."

They chose to look only astatine nan Chrome browser because it has nan highest marketplace share. A 2022 study [PDF] by a different group of academics recovered Chrome connected Android to beryllium "the greenest browser" for playing videos connected Vimeo and browsing Facebook, but amazingly not for Google Search.
"Based connected our results, we counsel users to entree net contented utilizing autochthonal apps complete Web apps, erstwhile imaginable to optimize nan artillery life of their devices," nan boffins authorities successful their paper.
They opportunity that while it whitethorn not beryllium realistic to expect that developers will take betwixt autochthonal and web apps solely connected nan ground of power depletion and performance, web apps should service chiefly for personification acquisition and not level interaction.
The insubstantial cites various imaginable threats to validity for illustration caching behaviour (loading assets from a section cache and frankincense not complete nan network), which they opportunity they dealt pinch by clearing autochthonal app caches connected each trial run, and ads, which they (mostly) blocked astatine a web level utilizing AdGuard DNS.
Missing from nan insubstantial wholly is nan connection "privacy," which The Register inquired astir but received nary contiguous consequence from nan researchers.
In nan absence of network-level blocking of advertisement and search scripts, web apps person nan imaginable to connection much privateness and champion customizability than their autochthonal counterparts, astatine slightest successful Android browsers for illustration Firefox aliases Kiwi that support privacy-enhancing extensions. ®
