This application may be the culprit causing the rapid battery drain of iOS 15

On September 20, Apple officially released iOS 15 for compatible devices. As usual, users started to detect and report problems with the new operating system.

Besides the problem from Apple, some third-party applications that are not compatible with the new operating system will also cause trouble for users. Over the past week, music streaming service Spotify has received many complaints from iPhone users about their application consuming about 30% of battery every hour of music playback.

This issue was reported by users upgrading from iOS 14.8 to iOS 15, and Spotify said it is investigating.

"We have forwarded the complaint information to the relevant team and we can confirm that they are currently looking into it," Spotify said. "In addition to trying restarting and/or reinstalling the Spotify app from scratch, you can also disable Background App Refresh by going to Settings > General > App Refresh in the background (Settings > General > Background App Refresh)".

Besides draining the battery like drinking water, some users also report that Spotify makes their devices hot like coals. Most responded that the fixes that Spotify offered did not work.

Apple has not yet commented or resolved the issue.

Spotify is Apple Music's main competitor in the music streaming app market. Spotify's subscriber base is growing steadily and is expected to surpass Apple Music by the end of the year.
